【老年患者用药】接受本品治疗的825 例胃肠间质瘤（GIST）和晚期/转移性肾细胞癌（MRCC）患者中有277 例（34%）年龄在65岁或65岁以上。未发现年轻患者与老年患者在安全性或有效性方面存在差异。

【孕妇及哺乳期妇女用药】 妊娠分类D 由于血管形成是胚胎和胎儿发育的关键，舒尼替尼抑制血管形成，可能对妊娠产生不良作用。未在孕妇中对本品进行充分的、严格对照的研究。如果患者妊娠期间使用本品或接受本品治疗期间妊娠，应告知患者药物对胎儿的潜在危害。育龄妇女接受本品治疗时应避孕。 在妊娠大鼠（0.3， 1.5， 3.0， 5.0 mg/kg/日剂量）和妊娠家兔（0.5， 1， 5， 20 mg/kg/日剂量）中评价了舒尼替尼对胚胎的影响。5mg/kg/日剂量时（约为人推荐日剂量[RDD]AUC 的5.5 倍），观察到大鼠的胚胎死亡和发育异常的发生率明显增加。家兔实验中，5mg/kg/日剂量时发现胚胎死亡发生率明显增加，当剂量≥1 mg/kg/日时（约为人推荐日剂量50mg/日时AUC 的0.3 倍）发现发育异常。对发育的影响包括大鼠胎仔的肋骨和椎骨的骨骼畸形发生率增加。家兔实验中，1 mg/kg/日剂量观察到唇裂，5mg/kg/日（约为人推荐日剂量AUC 的2.7 倍）剂量观察到唇裂和腭裂。大鼠实验中，当剂量≤3 mg/kg/日时（约为人推荐日剂量的2.3 倍）未见胎仔流产或畸形。 哺乳妇女

【药物相互作用】CYP3A4 抑制剂：CYP3A4 强抑制剂，如酮康唑，可增加舒尼替尼的血浆浓度。建议选择对此类酶没有或只有最小抑制作用的合并用药。如果必须与CYP3A4 强抑制剂同时应用时，需要考虑降低本品剂量。健康志愿者服用单剂量苹果酸舒尼替尼，同时给予CYP3A4 强抑制剂（酮康唑），可导致总体（舒尼替尼及其主要活性代谢产物）的Cmax 和AUC0-∞分别增加49% 和51% 。舒尼替尼与CYP3A4 酶系强抑制剂（例如：酮康唑、伊曲康唑、克拉霉素、atazanavir 、印地那韦、萘法唑酮、那非那韦、利托那韦、沙奎那韦、泰利霉素、伏立康唑）同时应用时，可增加舒尼替尼浓度，葡萄柚也可增加舒尼替尼的血药浓度。如果必须与CYP3A4 强抑制剂同时应用时，需要考虑降低本品剂量。 CYP3A4 诱导剂：CYP3A4 诱导剂，如利福平，可降低舒尼替尼的血浆浓度。建议选择对此类酶没有或只有最小诱导作用的合并用药。健康志愿者服用单剂舒尼替尼，同时给予CYP3A4 强诱导剂（利福平），可导致总体（舒尼替尼及其主要活性代谢产物）的Cmax 和AUC0-∞分别降低23% 和46% 。舒尼替

【药物过量】处理本品药物过量的方法包括一般的支持性措施。无治疗本品过量的特效解毒剂。如果有临床指征时，应采用催吐或洗胃清除未吸收的药物。已完成的临床研究中未有本品药物过量的报告。非临床研究中在500mg/kg（3000mg/m2）/日，最少给药5 天即观察到大鼠死亡。在此剂量水平，毒性反应征象包括肌肉协调障碍、摇头、活动减退、眼睛分泌物、竖毛和胃肠道不适。在更低剂量水平但更长治疗持续时间时也观察到死亡及相似的毒性反应征象。

【药理毒理】 药理作用 苹果酸舒尼替尼是一种能抑制多个受体酪氨酸激酶（RTK）的小分子，其中某些受体酪氨酸激酶参与肿瘤生长、病理性血管形成和肿瘤转移的过程。通过对舒尼替尼抑制各种激酶（80多种激酶）的活性进行评价，证明舒尼替尼可抑制血小板衍生生长因子受体(PDGFR α和 PDGFRβ)、血管内皮生长因子受体（VEGFR1、VEGFR2 和VEGFR3）、干细胞因子受体（KIT）、Fms 样酪氨酸激酶-3（FLT3）、1型集落刺激因子受体（CSF-1R）和神经胶质细胞系衍生的神经营养因子受体（RET）。生化和细胞测定证实舒尼替尼能抑制这些受体酪氨酸激酶（RTK）的活性，并在细胞增殖测定中证明了舒尼替尼的抑制作用。生化和细胞测定表明主要代谢物与舒尼替尼活性相似。 在表达受体酪氨酸激酶靶点的肿瘤模型的体内试验中，舒尼替尼能抑制多个受体酪氨酸激酶（PDGFR β、VEGFR2 、KIT） 的磷酸化进程；在某些动物肿瘤模型中显示出抑制肿瘤生长或导致肿瘤消退，和/或抑制肿瘤转移的作用。体外实验结果表明苹果酸舒尼替尼能抑制靶向受体酪氨酸激酶（PDGFR、RET 或KIT）表达失调的肿瘤细胞生长，体内试验结果表明其能抑制PDGFRβ-和VEGFR2-依赖的肿瘤血管形成。 毒理研究 重复给药毒性：一项3个月的猴重复给药试验（2，6，12mg/kg/日剂量）研究了药物对雌性生殖系统的影响，12 mg/kg/日剂量（约为推荐人用日剂量[RDD]的AUC 的5.1 倍）观察到卵巢变化（卵泡发育下降）；在≥2 mg/kg/日剂量（约为推荐人用日剂量[RDD] 的AUC 的0.4 倍）观察到子宫变化（子宫内膜萎缩）。在一项9个月的猴重复给药研究中，6mg/kg/日剂量时除阴道萎缩外，还对子宫和卵巢有影响（每日给药0.3， 1.5 和6 mg/kg/日剂量，连续给药28天，停药14天，6 mg/kg/日剂量产生的平均AUC 约为推荐人用日剂量[RDD] AUC 的0.8 倍）。3个月的研究中未明确无毒性效应水平；9个月的研究中无毒性效应剂量水平为1.5mg/kg/日。 生殖毒性：虽然舒尼替尼不影响大鼠的生育能力，但可能损害人的生育能力。雌性大鼠每天给药≤5.0 mg/kg/日剂量未发现生殖毒性(0.5，1.5，5.0 mg/kg/日剂量，给

【药代动力学】 尚缺乏中国人群的药代动力学研究数据，以下均为来自国外的人体药代动力学研究数据。 已在135 例健康志愿者和266 例实体瘤患者中评价了舒尼替尼和苹果酸舒尼替尼的药代动力学。 吸收、分布、代谢和排泄 一般在口服给药后6-1 2小时（Tmax）舒尼替尼达到最大血浆浓度（Cmax）。进食对舒尼替尼生物利用度无影响。与食物同服或不同服均可。 体外实验表明舒尼替尼及其主要活性代谢物的人血浆蛋白结合率分别为95% 和90% ，在100-4000ng/mL 范围内无浓度依赖。舒尼替尼的表观分布容积 (Vd/F)为 2230L. 在25-100mg 的剂量范围内， 血浆药时曲线下面积 (AUC)和最大血浆浓度（Cmax）随剂量成比例增加。 舒尼替尼主要由细胞色素P450 CYP3A4 代谢，产生的主要活性代谢物被CYP3A4 进一步代谢。其主要活性代谢物占总暴露量的23-37%。主要通过粪便排泄。在一项[14C] 标记的舒尼替尼质量平衡的人体试验中，剂量的61% 是通过粪便排出，而肾脏排泄的药物和代谢物约占剂量的16% 。舒尼替尼和主要活性代谢物在血浆、尿和粪便中发现的主要药物相关成分，分别代表了合并标本中的91.5% 、86.4 % 和73.8% 的放射活性。尿和粪便中能检测到次要代谢物，但在血浆中一般未能发现。总口服清除率（CL/F）为34-62 升/小时，患者间的变异系数为40% 。 健康志愿者口服单剂量舒尼替尼后，舒尼替尼和主要活性代谢物的终末半衰期分别为40-60 小时和80-110 小时。每日重复给药后，舒尼替尼蓄积3-4 倍，而其主要代谢物蓄积7-10 倍，在10-14 天内舒尼替尼和主要活性代谢物达稳态浓度。第14 天血浆舒尼替尼和主要活性代谢物的总浓度为62.9-101 ng/mL。每日重复给药或按治疗方案重复周期给药，未发现舒尼替尼和主要活性代谢物的药代动力学有明显的变化。 受试的健康志愿者和实体瘤患者的药代动力学相似，包括胃肠道间质瘤（GIST）和晚期/转移性肾细胞癌（MRCC）患者。 特殊群体 群体药代动力学分析的人口学数据表明年龄、体重、肌酐清除率、人种、性别或ECOG 体力状态评分对舒尼替尼或其活性代谢物的药代动力学没有临床相关性影响 。

Sutent is indicated for the adjuvant treatment of adult patients at high risk of recurrent RCC following nephrectomy.

Advanced Pancreatic Neuroendocrine Tumors (pNET)

Sutent is indicated for the treatment of progressive, well-differentiated pancreatic neuroendocrine tumors in patients with unresectable locally advanced or metastatic disease.

 

 

 

Sutent Dosage and Administration

Recommended Dose for GIST and Advanced RCC

The recommended dose of Sutent for gastrointestinal stromal tumor (GIST) and advanced renal cell carcinoma (RCC) is one 50 mg oral dose taken once daily, on a schedule of 4 weeks on treatment followed by 2 weeks off (Schedule 4/2). Sutent may be taken with or without food.

Recommended Dose for Adjuvant Treatment of RCC

The recommended dose of Sutent for the adjuvant treatment of RCC is 50 mg taken orally once daily, on a schedule of 4 weeks on treatment followed by 2 weeks off (Schedule 4/2), for nine 6-week cycles. Sutent may be taken with or without food.

Recommended Dose for pNET

The recommended dose of Sutent for pancreatic neuroendocrine tumors (pNET) is 37.5 mg taken orally once daily continuously without a scheduled off-treatment period. Sutent may be taken with or without food.

Dose Modification

Dose interruption and/or dose modification in 12.5 mg increments or decrements is recommended based on individual safety and tolerability. The maximum dose administered in the pNET study was 50 mg daily. In the adjuvant RCC study, the minimum dose administered was 37.5 mg.

Strong CYP3A4 inhibitors such as ketoconazole may increase sunitinib plasma concentrations. Selection of an alternate concomitant medication with no or minimal enzyme inhibition potential is recommended. A dose reduction for Sutent to a minimum of 37.5 mg (GIST and RCC) or 25 mg (pNET) daily should be considered if Sutent must be coadministered with a strong CYP3A4 inhibitor [see Drug Interactions (7.1)and Clinical Pharmacology (12.3)].

CYP3A4 inducers such as rifampin may decrease sunitinib plasma concentrations. Selection of an alternate concomitant medication with no or minimal enzyme induction potential is recommended. A dose increase for Sutent to a maximum of 87.5 mg (GIST and RCC) or 62.5 mg (pNET) daily should be considered if Sutent must be coadministered with a CYP3A4 inducer. If dose is increased, the patient should be monitored carefully for toxicity [see Drug Interactions (7.2) and Clinical Pharmacology (12.3)].

Warnings and Precautions

Hepatotoxicity

Sutent can cause severe hepatotoxicity, resulting in liver failure or death. Liver failure occurred at an incidence of <1% in clinical trials. Liver failure signs include jaundice, elevated transaminases and/or hyperbilirubinemia in conjunction with encephalopathy, coagulopathy, and/or renal failure. Monitor liver function tests (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and bilirubin) before initiation of treatment, during each cycle of treatment, and as clinically indicated. Interrupt Sutent for Grade 3 or 4 drug-related hepatic adverse reactions and discontinue if there is no resolution. Do not restart Sutent if patients subsequently experience severe changes in liver function tests or have other signs and symptoms of liver failure.

Safety in patients with ALT or AST >2.5 × upper limit of normal (ULN) or, if due to liver metastases, >5.0 × ULN has not been established.

Cardiovascular Events

Discontinue Sutent in the presence of clinical manifestations of congestive heart failure (CHF). Interrupt Sutent and/or reduce the dose in patients without clinical evidence of CHF who have an ejection fraction of >20% but <50% below baseline or below the lower limit of normal if baseline ejection fraction is not obtained.

In patients without cardiac risk factors a baseline evaluation of ejection fraction should be considered. Carefully monitor patients for clinical signs and symptoms of CHF while receiving Sutent. Baseline and periodic evaluations of left ventricular ejection fraction (LVEF) should also be considered while these patients are receiving Sutent.

Cardiovascular events, including heart failure, cardiomyopathy, myocardial ischemia, and myocardial infarction, some of which were fatal, have been reported.

In patients treated with Sutent (N=7527) for GIST, advanced RCC, adjuvant treatment of RCC and pNET, 3% of patients experienced heart failure; 71% of the patients with heart failure were reported as recovered. Fatal cardiac failure was reported in <1% of patients.

In the adjuvant treatment of RCC study, 11 patients in each arm experienced a decreased ejection fraction meeting Grade 2 CTCAE criteria (LVEF 40–50% and a 10–19% decrease from baseline). No patients had a Grade 3–4 decrease in ejection fraction. The ejection fractions of three patients in the Sutent arm and 2 patients in the placebo arm did not return to ≥50% or baseline by the time of last measurement. No patients who received Sutent were diagnosed with CHF.

Patients who presented with cardiac events within 12 months prior to Sutent administration, such as myocardial infarction (including severe/unstable angina), coronary/peripheral artery bypass graft, symptomatic CHF, cerebrovascular accident or transient ischemic attack, or pulmonary embolism were excluded from Sutent clinical studies. It is unknown whether patients with these concomitant conditions may be at a higher risk of developing drug-related left ventricular dysfunction.

QT Interval Prolongation and Torsade de Pointes

Sutent can cause QT interval prolongation in a dose-dependent manner, which may lead to an increased risk for ventricular arrhythmias including Torsade de Pointes. Torsade de Pointes has been observed in <0.1% of Sutent-exposed patients.

Monitor patients with a history of QT interval prolongation, patients who are taking antiarrhythmics, or patients with relevant pre-existing cardiac disease, bradycardia, or electrolyte disturbances. When using Sutent, periodic monitoring with on-treatment electrocardiograms and electrolytes (magnesium, potassium) should be considered. Concomitant treatment with strong CYP3A4 inhibitors may increase sunitinib plasma concentrations and dose reduction of Sutent should be considered [see Dosage and Administration (2.4)].

Hypertension

Monitor patients for hypertension and treat as needed with standard antihypertensive therapy. In cases of severe hypertension, temporary suspension of Sutent is recommended until hypertension is controlled.

In patients treated with Sutent (N=7527) in GIST, advanced RCC, adjuvant treatment of RCC and pNET, 29% of patients experienced hypertension. Grade 3 hypertension was reported in 7% of patients, and Grade 4 hypertension was reported in 0.2% of patients.

Hemorrhagic Events and Viscus Perforation

Hemorrhagic events reported through postmarketing experience, some of which were fatal, have included GI, respiratory, tumor, urinary tract, and brain hemorrhages. In patients treated with Sutent (N=7527) for GIST, advanced RCC, adjuvant treatment of RCC and pNET, 30% of patients experienced hemorrhagic events, and 4.2% of patients experienced a Grade 3 or 4 event. Epistaxis was the most common hemorrhagic adverse reaction and gastrointestinal hemorrhage was the most common Grade ≥3 event.

Tumor-related hemorrhage has been observed in patients treated with Sutent. These events may occur suddenly, and in the case of pulmonary tumors, may present as severe and life-threatening hemoptysis or pulmonary hemorrhage. Cases of pulmonary hemorrhage, some with a fatal outcome, have been observed in clinical trials and have been reported in postmarketing experience in patients treated with Sutent for metastatic RCC, GIST, and metastatic lung cancer. Sutent is not approved for use in patients with lung cancer. Clinical assessment of hemorrhagic events should include serial complete blood counts (CBCs) and physical examinations.

Serious, sometimes fatal, gastrointestinal complications including gastrointestinal perforation, have been reported in patients with intra-abdominal malignancies treated with Sutent.

Tumor Lysis Syndrome (TLS)

Cases of TLS, some fatal, occurred in clinical trials and have been reported in postmarketing experience, primarily in patients with RCC or GIST treated with Sutent. Patients generally at risk of TLS are those with high tumor burden prior to treatment. Monitor these patients closely and treat as clinically indicated.

Thrombotic Microangiopathy

Thrombotic microangiopathy (TMA), including thrombotic thrombocytopenic purpura and hemolytic uremic syndrome, sometimes leading to renal failure or a fatal outcome, occurred in clinical trials and in postmarketing experience of Sutent as monotherapy and administered in combination with bevacizumab. Discontinue Sutent in patients developing TMA. Reversal of the effects of TMA has been observed after treatment was discontinued.

Proteinuria

Proteinuria and nephrotic syndrome have been reported. Some of these cases have resulted in renal failure and fatal outcomes. Monitor patients for the development or worsening of proteinuria. Perform baseline and periodic urinalyses during treatment, with follow up measurement of 24-hour urine protein as clinically indicated. Interrupt Sutent and dose reduce for 24-hour urine protein ≥3 grams. Discontinue Sutent for patients with nephrotic syndrome or repeat episodes of urine protein ≥3 grams despite dose reductions. The safety of continued Sutent treatment in patients with moderate to severe proteinuria has not been systematically evaluated.

Dermatologic Toxicities

Severe cutaneous reactions have been reported, including cases of erythema multiforme (EM), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), some of which were fatal. If signs or symptoms of EM, SJS, or TEN (e.g., progressive skin rash often with blisters or mucosal lesions) are present, discontinue Sutent treatment. If a diagnosis of SJS or TEN is suspected, Sutent treatment must not be re-started.

Necrotizing fasciitis, including fatal cases, has been reported in patients treated with Sutent, including of the perineum and secondary to fistula formation. Discontinue Sutent in patients who develop necrotizing fasciitis.

Thyroid Dysfunction

Baseline laboratory measurement of thyroid function is recommended and patients with hypothyroidism or hyperthyroidism should be treated as per standard medical practice prior to the start of Sutent treatment. All patients should be observed closely for signs and symptoms of thyroid dysfunction, including hypothyroidism, hyperthyroidism, and thyroiditis, while on Sutent treatment. Patients with signs and/or symptoms suggestive of thyroid dysfunction should have laboratory monitoring of thyroid function performed and be treated as per standard medical practice.

Cases of hyperthyroidism, some followed by hypothyroidism, have been reported in clinical trials and through postmarketing experience.

Hypoglycemia

Sutent can result in symptomatic hypoglycemia, which may lead to loss of consciousness, or require hospitalization. Hypoglycemia has occurred in clinical trials in 2% of the patients treated with Sutent for advanced RCC and GIST and in approximately 10% of the patients treated with Sutent for pNET. In the adjuvant treatment of RCC study, no patients on Sutent experienced hypoglycemia. For patients being treated with Sutent for pNET, pre-existing abnormalities in glucose homeostasis were not present in all patients who experienced hypoglycemia. Reductions in blood glucose levels may be worse in diabetic patients. Check blood glucose levels regularly during and after discontinuation of treatment with Sutent. Assess if antidiabetic drug dosage needs to be adjusted to minimize the risk of hypoglycemia.

Osteonecrosis of the Jaw (ONJ)

ONJ has been observed in clinical trials and has been reported in postmarketing experience in patients treated with Sutent. Concomitant exposure to other risk factors, such as bisphosphonates or dental disease, may increase the risk of osteonecrosis of the jaw. Consider preventive dentistry prior to treatment with Sutent. If possible, avoid invasive dental procedures while on Sutent treatment, particularly in patients receiving intravenous bisphosphonate therapy.

Wound Healing

Cases of impaired wound healing have been reported during Sutent therapy. Temporary interruption of Sutent therapy is recommended for precautionary reasons in patients undergoing major surgical procedures. There is limited clinical experience regarding the timing of reinitiation of therapy following major surgical intervention. Therefore, the decision to resume Sutent therapy following a major surgical intervention should be based upon clinical judgment of recovery from surgery.

Embryo-Fetal Toxicity

Based on findings from animal studies and its mechanism of action, Sutent can cause fetal harm when administered to pregnant woman. Administration of sunitinib to pregnant rats and rabbits during the period of organogenesis resulted in teratogenicity at approximately 5.5 and 0.3 times the clinical systemic exposure (AUC) at the recommended daily doses (RDD) of 50 mg/day, respectively.

Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with Sutent and for 4 weeks following the final dose [see Clinical Pharmacology (12.1) and Use in Specific Populations (8.1, 8.3)].

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described in the Warnings and Precautions reflect exposure to Sutent (N = 7527) in GIST, advanced RCC, adjuvant treatment of RCC, and pNET [see Warnings and Precautions (5.1, 5.13)]. In this database, the most common adverse reactions (≥25%) are fatigue/asthenia, diarrhea, mucositis/stomatitis, nausea, decreased appetite/anorexia, vomiting, abdominal pain, hand-foot syndrome, hypertension, bleeding events, dysgeusia/altered taste, dyspepsia, and thrombocytopenia.

The data below reflect exposure to Sutent in 966 patients who participated in the treatment phase of randomized trials of GIST (n=202), advanced RCC (n=375), adjuvant treatment of RCC (n=306), and pNET (n=83) [see Clinical Studies (14.1, 14.2, 14.3)].

Gastrointestinal Stromal Tumor (GIST)

The safety of Sutent was evaluated in Study 1, a randomized, double-blind, placebo-controlled trial in which previously treated patients with GIST received Sutent 50 mg daily on Schedule 4/2 (n=202) or placebo (n=102).

Median duration of blinded study treatment was 2 cycles for patients on Sutent (mean: 3.0; range: 1–9) and 1 cycle (mean; 1.8; range: 1–6) for patients on placebo at the time of the interim analysis. Dose reductions occurred in 23 patients (11%) on Sutent and none on placebo. Dose interruptions occurred in 59 patients (29%) on Sutent and 31 patients (30%) on placebo. The rates of treatment-emergent, nonfatal adverse reactions resulting in permanent discontinuation were 7% and 6% in the Sutent and placebo groups, respectively.

Most treatment-emergent adverse reactions in both study arms were Grade 1 or 2 in severity. Grade 3 or 4 treatment-emergent adverse reactions were reported in 56% versus 51% of patients on Sutent versus placebo, respectively, in the double-blind treatment phase of the trial. Table 1 compares the incidence of common (≥10%) treatment-emergent adverse reactions for patients receiving Sutent and reported more commonly in patients receiving Sutent than in patients receiving placebo.

After an interim analysis, the study was unblinded and patients on the placebo arm were given the opportunity to receive open-label Sutent treatment [see Clinical Studies (14.1)]. For 241 patients randomized to the Sutent arm, including 139 who received Sutent in both the double-blind and open-label treatment phases, the median duration of Sutent treatment was 6 cycles (mean: 8.5; range: 1–44). For the 255 patients who ultimately received open-label Sutent treatment, median duration of study treatment was 6 cycles (mean: 7.8; range: 1–37) from the time of the unblinding. A total of 118 patients (46%) required dosing interruptions, and a total of 72 patients (28%) required dose reductions. The incidence of treatment-emergent adverse reactions resulting in permanent discontinuation was 20%. The most common Grade 3 or 4 treatment-related adverse reactions experienced by patients receiving Sutent in the open-label treatment phase were fatigue (10%), hypertension (8%), asthenia (5%), diarrhea (5%), hand-foot syndrome (5%), nausea (4%), abdominal pain (3%), anorexia (3%), mucositis (2%), vomiting (2%), and hypothyroidism (2%).

Advanced Renal Cell Carcinoma (RCC)

The safety of Sutent was evaluated in Study 3, a double-blind, active-controlled trial in which previously untreated patients with locally advanced or metastatic RCC received Sutent 50 mg daily on Schedule 4/2 (n=375) or IFN-α 9 million International Units (MIU) (n=360). The median duration of treatment was 11.1 months (range: 0.4–46.1) for Sutent treatment and 4.1 months (range: 0.1–45.6) for IFN-α treatment. Dose interruptions occurred in 202 patients (54%) on Sutent and 141 patients (39%) on IFN-α. Dose reductions occurred in 194 patients (52%) on Sutent and 98 patients (27%) on IFN-α. Discontinuation rates due to adverse reactions were 20% for Sutent and 24% for IFN-α. Most treatment-emergent adverse reactions in both study arms were Grade 1 or 2 in severity. Grade 3 or 4 treatment-emergent adverse reactions were reported in 77% versus 55% of patients on Sutent versus IFN-α, respectively.

Table 3 compares the incidence of common (≥10%) treatment-emergent adverse reactions for patients receiving Sutent versus IFN-α.

Long-Term Safety in RCC

The long-term safety of Sutent in patients with metastatic RCC was analyzed across 9 completed clinical studies conducted in the first-line, bevacizumab-refractory, and cytokine-refractory treatment settings. The analysis included 5739 patients, of whom 807 (14%) were treated for at least 2 years and 365 (6%) for at least 3 years. Prolonged treatment with Sutent did not appear to be associated with new types of adverse reactions. There appeared to be no increase in the yearly incidence of adverse reactions at later time points. Hypothyroidism increased during the second year of treatment with new cases reported up to year 4.

Adjuvant Treatment of RCC

The safety of Sutent was evaluated in S-TRAC, a randomized, double-blind, placebo-controlled trial in which patients who had undergone nephrectomy for RCC received Sutent 50 mg daily (n=306) on Schedule 4/2 or placebo (n=304). The median duration of treatment was 12.4 months (range: 0.13–14.9) for Sutent and 12.4 months (range: 0.03–13.7) for placebo. Permanent discontinuation due to an adverse reaction occurred in 28% of patients on Sutent and 6% on placebo. Adverse reactions leading to permanent discontinuation in >2% of patients include hand-foot syndrome and fatigue/asthenia. Dosing interruptions or delays occurred in 166 (54%) and 84 (28%) patients on Sutent and placebo, respectively. One hundred forty patients (45.8%) out of 306 patients in the Sutent arm and 15 patients (5%) out of 304 patients in the placebo arm had dose reductions.

Table 5 compares the incidence of common (≥10%) treatment-emergent adverse reactions for patients receiving Sutent versus placebo.

Grade 4 adverse reactions in patients on Sutent included hand-foot syndrome (1%), fatigue (<1%), abdominal pain (< 1%), stomatitis (<1%), and pyrexia (< 1%). Grade 4 adverse reactions in patients on placebo included asthenia (<1%) and hypertension (<1%).

Grade 3–4 laboratory abnormalities that occurred in ≥2% of patients receiving Sutent include neutropenia (13%), thrombocytopenia (5%), leukopenia (3%), lymphopenia (3%), elevated alanine aminotransferase (2%), elevated aspartate aminotransferase (2%), hyperglycemia (2%), and hyperkalemia (2%).

Advanced Pancreatic Neuroendocrine Tumors (pNET)

The safety of Sutent was evaluated in Study 6, a randomized, double-blind, placebo-controlled trial in which patients with progressive pNET received Sutent 37.5 mg daily continuous dosing (n=83) or placebo (n=82). The median number of days on treatment was 139 days (range: 13–532 days) for patients on Sutent and 113 days (range: 1–614 days) for patients on placebo. Nineteen patients (23%) on Sutent and 4 patients (5%) on placebo were on study for >1 year. Dose interruptions occurred in 25 patients (30%) on Sutent and 10 patients (12%) on placebo. Dose reductions occurred in 26 patients (31%) on Sutent and 9 patients (11%) on placebo. Discontinuation rates due to adverse reactions were 22% for Sutent and 17% for placebo.

Most treatment-emergent adverse reactions in both study arms were Grade 1 or 2 in severity. Grade 3 or 4 treatment-emergent adverse reactions were reported in 54% versus 50% of patients on Sutent versus placebo, respectively. Table 6 compares the incidence of common (≥10%) treatment-emergent adverse reactions for patients receiving Sutent and reported more commonly in patients receiving Sutent than in patients receiving placebo.

Venous Thromboembolic Events

In patients treated with Sutent (N=7527) for GIST, advanced RCC, adjuvant treatment of RCC and pNET, 3.5% of patients experienced a venous thromboembolic event; 2.2% Grade 3–4.

Reversible Posterior Leukoencephalopathy Syndrome

There have been reports (<1%), some fatal, of patients presenting with seizures and radiological evidence of reversible posterior leukoencephalopathy syndrome (RPLS). Patients with seizures and signs/symptoms consistent with RPLS, such as hypertension, headache, decreased alertness, altered mental functioning, and visual loss, including cortical blindness, should be controlled with medical management including control of hypertension. Temporary suspension of Sutent is recommended; following resolution, treatment may be resumed at the discretion of the treating healthcare provider.

Pancreatic Function

Pancreatitis was observed in 5 patients (1%) receiving Sutent for treatment-naïve RCC compared to 1 patient (<1%) receiving IFN-α. In a trial of patients receiving adjuvant treatment for RCC, 1 patient (<1%) on Sutent and none on placebo experienced pancreatitis. Pancreatitis was observed in 1 patient (1%) receiving Sutent for pNET and 1 patient (1%) receiving placebo.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of Sutent. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

 

Blood and lymphatic system disorders: hemorrhage associated with thrombocytopenia1. Suspension of Sutent is recommended; following resolution, treatment may be resumed at the discretion of the treating healthcare provider.

 

Gastrointestinal disorders: esophagitis.

 

Hepatobiliary disorders: cholecystitis, particularly acalculous cholecystitis.

 

Immune system disorders: hypersensitivity reactions, including angioedema.

 

Infections and infestations: serious infection (with or without neutropenia)1. The infections most commonly observed with Sutent treatment include respiratory, urinary tract, skin infections, and sepsis/septic shock.

 

Musculoskeletal and connective tissue disorders: fistula formation, sometimes associated with tumor necrosis and/or regression1; myopathy and/or rhabdomyolysis with or without acute renal failure1. Patients with signs or symptoms of muscle toxicity should be managed as per standard medical practice.

 

Renal and urinary disorders: renal impairment and/or failure1.

 

Respiratory disorders: pulmonary embolism1.

 

Skin and subcutaneous tissue disorders: pyoderma gangrenosum, including positive dechallenges.

 

Vascular disorders: arterial thromboembolic events1. The most frequent events included cerebrovascular accident, transient ischemic attack, and cerebral infarction.

including some fatalities.

Drug Interactions

CYP3A4 Inhibitors

Strong CYP3A4 inhibitors such as ketoconazole may increase sunitinib plasma concentrations. Selection of an alternate concomitant medication with no or minimal enzyme inhibition potential is recommended. Concurrent administration of Sutent with the strong CYP3A4 inhibitor, ketoconazole, resulted in 49% and 51% increases in the combined (sunitinib + primary active metabolite) Cmax and AUC0–∞ values, respectively, after a single dose of Sutent in healthy volunteers. Coadministration of Sutent with strong inhibitors of the CYP3A4 family (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole) may increase sunitinib concentrations. Grapefruit may also increase plasma concentrations of sunitinib. A dose reduction for Sutent should be considered when it must be coadministered with strong CYP3A4 inhibitors [see Dosage and Administration (2.4)].

CYP3A4 Inducers

CYP3A4 inducers such as rifampin may decrease sunitinib plasma concentrations. Selection of an alternate concomitant medication with no or minimal enzyme induction potential is recommended. Concurrent administration of Sutent with the strong CYP3A4 inducer, rifampin, resulted in a 23% and 46% reduction in the combined (sunitinib + primary active metabolite) Cmax and AUC0–∞ values, respectively, after a single dose of Sutent in healthy volunteers. Coadministration of Sutent with inducers of the CYP3A4 family (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, St. John's Wort) may decrease sunitinib concentrations. St. John's Wort may decrease sunitinib plasma concentrations unpredictably. Patients receiving Sutent should not take St. John's Wort concomitantly. A dose increase for Sutent should be considered when it must be coadministered with CYP3A4 inducers [see Dosage and Administration (2.4)].

In Vitro Studies of CYP Inhibition and Induction

In vitro studies indicated that sunitinib does not induce or inhibit major CYP enzymes. The in vitro studies in human liver microsomes and hepatocytes of the activity of CYP isoforms CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4/5, and CYP4A9/11 indicated that sunitinib and its primary active metabolite are unlikely to have any clinically relevant drug-drug interactions with drugs that may be metabolized by these enzymes.

USE IN SPECIFIC POPULATIONS

Pregnancy

Risk Summary

Based on animal reproduction studies and its mechanism of action, Sutent can cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data in pregnant women to inform a drug-associated risk. In animal developmental and reproductive toxicology studies, oral administration of sunitinib to pregnant rats and rabbits throughout organogenesis resulted in teratogenicity (embryolethality, craniofacial and skeletal malformations) at 5.5 and 0.3 times the AUC in patients administered the recommended daily doses (RDD), respectively (see Data). Advise pregnant women or females of reproductive potential of the potential hazard to a fetus.

The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the estimated background risk in the United States (U.S.) general population of major birth defects is 2%–4% and of miscarriage is 15%–20% of clinically recognized pregnancies.

Data

Animal Data

In a female fertility and early embryonic development study, female rats were administered oral sunitinib (0.5, 1.5, 5 mg/kg/day) for 21 days prior to mating and for 7 days after mating. Embryolethality was observed at 5 mg/kg/day (approximately 5 times the AUC in patients administered the RDD of 50 mg/day).

In embryo-fetal developmental toxicity studies, oral sunitinib was administered to pregnant rats (0.3, 1.5, 3, 5 mg/kg/day) and rabbits (0.5, 1, 5, 20 mg/kg/day) during the period of organogenesis. In rats, embryolethality and skeletal malformations of the ribs and vertebrae were observed at the dose of 5 mg/kg/day (approximately 5.5 times the systemic exposure [combined AUC of sunitinib + primary active metabolite] in patients administered the RDD). No adverse fetal effects were observed in rats at doses ≤3 mg/kg/day (approximately 2 times the AUC in patients administered the RDD). In rabbits, embryolethality was observed at 5 mg/kg/day (approximately 3 times the AUC in patients administered the RDD), and craniofacial malformations (cleft lip and cleft palate) were observed at ≥1 mg/kg/day (approximately 0.3 times the AUC in patients administered the RDD of 50 mg/day).

Sunitinib (0.3, 1, 3 mg/kg/day) was evaluated in a pre- and postnatal development study in pregnant rats. Maternal body weight gains were reduced during gestation and lactation at doses ≥1 mg/kg/day (approximately 0.5 times the AUC in patients administered the RDD). At 3 mg/kg/day (approximately 2 times the AUC in patients administered the RDD), reduced neonate body weights were observed at birth and persisted in the offspring of both sexes during the preweaning period and in males during postweaning period. No adverse developmental effects were observed at doses ≤1 mg/kg/day.

Lactation

There is no information regarding the presence of sunitinib and its metabolites in human milk. Sunitinib and its metabolites were excreted in rat milk at concentrations up to 12-fold higher than in plasma (see Data). Because of the potential for serious adverse reactions in breastfed infants from Sutent, advise a lactating woman not to breastfeed during treatment with Sutent and for at least 4 weeks after the last dose.

Data

Animal Data

In lactating female rats administered 15 mg/kg, sunitinib and its metabolites were excreted in milk at concentrations up to 12-fold higher than in plasma.

Females and Males of Reproductive Potential

Based on animal reproduction studies and its mechanism of action, Sutent can cause fetal harm when administered to a pregnant woman [see Pregnancy (8.1) and Clinical Pharmacology (12.1)].

Pregnancy Testing

Females of reproductive potential should have a pregnancy test before treatment with Sutent is started.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with Sutent and for at least 4 weeks after the last dose.

Males

Based on findings in animal reproduction studies, advise male patients with female partners of reproductive potential to use effective contraception during treatment with Sutent and for 7 weeks after the last dose.

Infertility

Based on findings in animals, male and female fertility may be compromised by treatment with Sutent [see Nonclinical Toxicology (13.1)].

Pediatric Use

The safety and efficacy of Sutent in pediatric patients have not been established.

Physeal dysplasia was observed in cynomolgus monkeys with open growth plates treated for ≥3 months (3 month dosing 2, 6, 12 mg/kg/day; 8 cycles of dosing 0.3, 1.5, 6.0 mg/kg/day) with sunitinib at doses that were >0.4 times the RDD based on systemic exposure (AUC). In developing rats treated continuously for 3 months (1.5, 5.0, and 15.0 mg/kg) or 5 cycles (0.3, 1.5, and 6.0 mg/kg/day), bone abnormalities consisted of thickening of the epiphyseal cartilage of the femur and an increase of fracture of the tibia at doses ≥5 mg/kg (approximately 10 times the RDD based on AUC). Additionally, caries of the teeth were observed in rats at >5 mg/kg. The incidence and severity of physeal dysplasia were dose related and were reversible upon cessation of treatment; however, findings in the teeth were not. A no-effect level was not observed in monkeys treated continuously for 3 months, but was 1.5 mg/kg/day when treated intermittently for 8 cycles. In rats the no-effect level in bones was ≤2 mg/kg/day.

Geriatric Use

Of 825 patients with GIST or metastatic RCC who received Sutent on clinical studies, 277 (34%) were 65 and over. In the pNET study, 22 patients (27%) who received Sutent were 65 and over. No overall differences in safety or effectiveness were observed between younger and older patients. Among the 158 patients at least age 65 receiving adjuvant Sutent/placebo for RCC, the hazard ratio for disease-free survival was 0.59 (95% CI: 0.36, 0.95). Among patients 65 years and older receiving adjuvant Sutent/placebo for RCC, 50 patients (16%) in the Sutent arm experienced a Grade 3–4 adverse reaction, compared to 15 patients (5%) in the placebo arm.

Hepatic Impairment

No dose adjustment to the starting dose is required when administering Sutent to patients with Child-Pugh Class A or B hepatic impairment. Sunitinib and its primary metabolite are primarily metabolized by the liver. Systemic exposures after a single dose of Sutent were similar in patients with mild or moderate (Child-Pugh Class A and B) hepatic impairment compared to patients with normal hepatic function. Sutent was not studied in patients with severe (Child-Pugh Class C) hepatic impairment. Studies in cancer patients have excluded patients with ALT or AST >2.5 × ULN or, if due to liver metastases, >5.0 × ULN.

Renal Impairment

No adjustment to the starting dose is required when administering Sutent to patients with mild (CLcr 50–80 mL/min), moderate (CLcr 30–<50 mL/min), or severe (CLcr <30 mL/min) renal impairment who are not on dialysis. In patients with end-stage renal disease (ESRD) on hemodialysis, no adjustment to the starting dose is required. However, compared to patients with normal renal function, the sunitinib exposure is 47% lower in patients with ESRD on hemodialysis. Therefore, the subsequent doses may be increased gradually up to 2-fold based on safety and tolerability.

Overdosage

Treatment of overdose with Sutent should consist of general supportive measures. There is no specific antidote for overdosage with Sutent. If indicated, elimination of unabsorbed drug should be achieved by emesis or gastric lavage. Cases of accidental overdose have been reported; these cases were associated with adverse reactions consistent with the known safety profile of Sutent, or without adverse reactions. A case of intentional overdose involving the ingestion of 1500 mg of Sutent in an attempted suicide was reported without adverse reaction. In nonclinical studies, mortality was observed following as few as 5 daily doses of 500 mg/kg (3000 mg/m2) in rats. At this dose, signs of toxicity included impaired muscle coordination, head shakes, hypoactivity, ocular discharge, piloerection, and gastrointestinal distress. Mortality and similar signs of toxicity were observed at lower doses when administered for longer durations.

Sutent Description

Sutent, an oral multi-kinase inhibitor, is the malate salt of sunitinib. Sunitinib malate is described chemically as Butanedioic acid, hydroxy-, (2S)-, compound with N-[2-(diethylamino)ethyl]-5-[(Z)-(5-fluoro-1,2-dihydro-2-oxo-3H-indol-3-ylidine)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxamide (1:1). The molecular formula is C22H27FN4O2 ∙ C4H6O5 and the molecular weight is 532.6 Daltons.

The chemical structure of sunitinib malate is:

 

Sunitinib malate is a yellow to orange powder with a pKa of 8.95. The solubility of sunitinib malate in aqueous media over the range pH 1.2 to pH 6.8 is in excess of 25 mg/mL. The log of the distribution coefficient (octanol/water) at pH 7 is 5.2.

Sutent (sunitinib malate) capsules are supplied as printed hard shell capsules containing sunitinib malate equivalent to 12.5 mg, 25 mg, 37.5 mg or 50 mg of sunitinib together with mannitol, croscarmellose sodium, povidone (K-25) and magnesium stearate as inactive ingredients.

The orange gelatin capsule shells contain titanium dioxide and red iron oxide. The caramel gelatin capsule shells contain titanium dioxide, red iron oxide, yellow iron oxide, and black iron oxide. The yellow gelatin capsule shells contain titanium dioxide and yellow iron oxide. The white printing ink contains shellac, propylene glycol, sodium hydroxide, povidone, and titanium dioxide. The black printing ink contains shellac, propylene glycol, potassium hydroxide, and black iron oxide.

Sutent - Clinical Pharmacology

Mechanism of Action

Sunitinib is a small molecule that inhibits multiple receptor tyrosine kinases (RTKs), some of which are implicated in tumor growth, pathologic angiogenesis, and metastatic progression of cancer. Sunitinib was evaluated for its inhibitory activity against a variety of kinases (>80 kinases) and was identified as an inhibitor of platelet-derived growth factor receptors (PDGFRα and PDGFRβ), vascular endothelial growth factor receptors (VEGFR1, VEGFR2, and VEGFR3), stem cell factor receptor (KIT), Fms-like tyrosine kinase-3 (FLT3), colony stimulating factor receptor Type 1 (CSF-1R), and the glial cell-line derived neurotrophic factor receptor (RET). Sunitinib inhibition of the activity of these RTKs has been demonstrated in biochemical and cellular assays, and inhibition of function has been demonstrated in cell proliferation assays. The primary metabolite exhibits similar potency compared to sunitinib in biochemical and cellular assays.

Sunitinib inhibited the phosphorylation of multiple RTKs (PDGFRβ, VEGFR2, KIT) in tumor xenografts expressing RTK targets in vivo and demonstrated inhibition of tumor growth or tumor regression and/or inhibited metastases in some experimental models of cancer. Sunitinib demonstrated the ability to inhibit growth of tumor cells expressing dysregulated target RTKs (PDGFR, RET, or KIT) in vitro and to inhibit PDGFRβ- and VEGFR2-dependent tumor angiogenesis in vivo.

Pharmacokinetics

The pharmacokinetics of sunitinib and sunitinib malate have been evaluated in 135 healthy volunteers and in 266 patients with solid tumors.

Maximum plasma concentrations (Cmax) of sunitinib are generally observed between 6 and 12 hours (time to maximum plasma concentration [Tmax]) following oral administration. Food has no effect on the bioavailability of sunitinib. Sutent may be taken with or without food.

Binding of sunitinib and its primary active metabolite to human plasma protein in vitro was 95% and 90%, respectively, with no concentration dependence in the range of 100–4000 ng/mL. The apparent volume of distribution (Vd/F) for sunitinib was 2230 L. In the dosing range of 25–100 mg, the AUC and Cmax increase proportionately with dose.

Sunitinib is metabolized primarily by the cytochrome P450 enzyme, CYP3A4, to produce its primary active metabolite, which is further metabolized by CYP3A4. The primary active metabolite comprises 23% to 37% of the total exposure. Elimination is primarily via feces. In a human mass balance study of [14C]sunitinib, 61% of the dose was eliminated in feces, with renal elimination accounting for 16% of the administered dose. Sunitinib and its primary active metabolite were the major drug-related compounds identified in plasma, urine, and feces, representing 91.5%, 86.4%, and 73.8% of radioactivity in pooled samples, respectively. Minor metabolites were identified in urine and feces but generally not found in plasma. Total oral clearance (CL/F) ranged from 34 to 62 L/h with an interpatient variability of 40%.

Following administration of a single oral dose in healthy volunteers, the terminal half-lives of sunitinib and its primary active metabolite are approximately 40 to 60 hours and 80 to 110 hours, respectively. With repeated daily administration, sunitinib accumulates 3- to 4-fold while the primary metabolite accumulates 7- to 10-fold. Steady-state concentrations of sunitinib and its primary active metabolite are achieved within 10 to 14 days. By Day 14, combined plasma concentrations of sunitinib and its active metabolite ranged from 62.9–101 ng/mL. No significant changes in the pharmacokinetics of sunitinib or the primary active metabolite were observed with repeated daily administration or with repeated cycles in the dosing regimens tested.

The pharmacokinetics were similar in healthy volunteers and in the solid tumor patient populations tested, including patients with GIST and RCC.

Pharmacokinetics in Special Populations

Population pharmacokinetic analyses of demographic data indicate that there are no clinically relevant effects of age, body weight, creatinine clearance, race, gender, or Eastern Cooperative Oncology Group (ECOG) score on the pharmacokinetics of Sutent or the primary active metabolite.

Pediatric Use: The pharmacokinetics of Sutent have not been evaluated in pediatric patients.

Renal Insufficiency: Sunitinib systemic exposure after a single dose of Sutent was similar in patients with severe renal impairment (CLcr <30 mL/min) compared to patients with normal renal function (CLcr >80 mL/min). Although sunitinib was not eliminated through hemodialysis, the sunitinib systemic exposure was 47% lower in patients with ESRD on hemodialysis compared to patients with normal renal function.

Hepatic Insufficiency: Systemic exposures after a single dose of Sutent were similar in patients with mild exocrine (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment compared to patients with normal hepatic function.

Cardiac Electrophysiology

Sutent can cause QT interval prolongation in a dose-dependent manner, which may lead to an increased risk for ventricular arrhythmias including Torsade de Pointes [see Warnings and Precautions (5.3)].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of sunitinib has been evaluated in 2 species: rasH2 transgenic mice and Sprague-Dawley rats. There were similar positive findings in both species. In rasH2 transgenic mice, gastroduodenal carcinomas and/or gastric mucosal hyperplasia, as well as an increased incidence of background hemangiosarcomas were observed at doses ≥25 mg/kg/day following daily dose administration of sunitinib in studies of 1 or 6 months duration. No proliferative changes were observed in rasH2 transgenic mice at 8 mg/kg/day. Similarly, in a 2-year rat carcinogenicity study, administration of sunitinib in 28-day cycles followed by 7-day dose-free periods resulted in findings of duodenal carcinoma at doses as low as 1 mg/kg/day (approximately 0.9 times the AUC in patients given the RDD of 50 mg/day). At the high dose of 3 mg/kg/day (approximately 8 times the AUC in patients at the RDD of 50 mg/day), the incidence of duodenal tumors was increased and was accompanied by findings of gastric mucous cell hyperplasia and by an increased incidence of pheochromocytoma and hyperplasia of the adrenal gland.

Sunitinib did not cause genetic damage when tested in in vitro assays (bacterial mutation [Ames test], human lymphocyte chromosome aberration) and an in vivo rat bone marrow micronucleus test.

In a female fertility and early embryonic development study, female rats were administered oral sunitinib (0.5, 1.5, 5 mg/kg/day) for 21 days prior to mating and for 7 days after mating. Preimplantation loss was observed in females administered 5 mg/kg/day (approximately 5 times the AUC in patients administered the RDD of 50 mg/day). No adverse effects on fertility were observed at doses ≤1.5 mg/kg/day (approximately 1 time the clinical AUC at the RDD of 50 mg/day). In addition, effects on the female reproductive system were identified in a 3-month oral repeat-dose monkey study (2, 6, 12 mg/kg/day). Ovarian changes (decreased follicular development) were noted at 12 mg/kg/day (approximately 5 times the AUC in patients administered the RDD), while uterine changes (endometrial atrophy) were noted at ≥2 mg/kg/day (approximately 0.4 times the AUC in patients administered the RDD). With the addition of vaginal atrophy, the uterine and ovarian effects were reproduced at 6 mg/kg/day (approximately 0.8 times the AUC in patients administered the RDD) in a 9-month monkey study (0.3, 1.5, and 6 mg/kg/day administered daily for 28 days followed by a 14 day respite).

In a male fertility study, no reproductive effects were observed in male rats dosed with 1, 3, or 10 mg/kg/day oral sunitinib for 58 days prior to mating with untreated females. Fertility, copulation, conception indices, and sperm evaluation (morphology, concentration, and motility) were unaffected by sunitinib at doses ≤10 mg/kg/day approximately ≥26 times the AUC in patients administered the RDD).

Clinical Studies

Gastrointestinal Stromal Tumor

Study 1

Study 1 (NCT#00075218) was a 2-arm, international, randomized, double-blind, placebo-controlled trial of Sutent in patients with GIST who had disease progression during prior imatinib mesylate (imatinib) treatment or who were intolerant of imatinib. The objective was to compare time-to-tumor progression (TTP) in patients receiving Sutent plus best supportive care versus patients receiving placebo plus best supportive care. Other objectives included progression-free survival (PFS), objective response rate (ORR), and overall survival (OS). Patients were randomized (2:1) to receive either 50 mg Sutent or placebo orally, once daily, on Schedule 4/2 until disease progression or withdrawal from the study for another reason. Treatment was unblinded at the time of disease progression. Patients randomized to placebo were then offered crossover to open-label Sutent and patients randomized to Sutent were permitted to continue treatment per investigator judgment.

At the time of a prespecified interim analysis, the intent-to-treat (ITT) population included 312 patients. Two hundred seven (207) patients were randomized to the Sutent arm and 105 patients were randomized to the placebo arm. Demographics were comparable between the Sutent and placebo groups with regard to age (69% versus 72% <65 years for Sutent versus placebo, respectively), gender (male: 64% versus 61%), race (White: 88% both arms, Asian: 5% both arms, Black: 4% both arms, remainder not reported), and performance status (ECOG 0: 44% versus 46%, ECOG 1: 55% versus 52%, and ECOG 2: 1% versus 2%). Prior treatment included surgery (94% versus 93%) and radiotherapy (8% versus 15%). Outcome of prior imatinib treatment was also comparable between arms with intolerance (4% versus 4%), progression within 6 months of starting treatment (17% versus 16%), or progression beyond 6 months (78% versus 80%) balanced.

The planned interim efficacy and safety analysis was performed after 149 TTP events had occurred. There was a statistically significant advantage for Sutent over placebo in TTP, meeting the primary endpoint. Efficacy results are summarized in Table 8 and the Kaplan-Meier curve for TTP is shown in Figure 1.

The final ITT population enrolled in the double-blind treatment phase of the study included 243 patients randomized to the Sutent arm and 118 patients randomized to the placebo arm. After the primary endpoint was met at the interim analysis, the study was unblinded, and patients on the placebo arm were offered open-label Sutent treatment. Ninety-nine (99) of the patients initially randomized to placebo crossed over to receive Sutent in the open-label treatment phase. At the protocol specified final analysis of OS, the median OS was 72.7 weeks for the Sutent arm and 64.9 weeks for the placebo arm [hazard ratio (HR)=0.876, 95% confidence interval (CI) (0.679, 1.129)].

Study 2

Study 2 was an open-label, multi-center, single-arm, dose-escalation study conducted in patients with GIST following progression on, or intolerance to imatinib. Following identification of the recommended regimen (50 mg once daily on Schedule 4/2), 55 patients in this study received the 50 mg dose of Sutent on treatment Schedule 4/2. Partial responses (PR) were observed in 5 of 55 patients (9.1% PR rate; 95% CI: 3.0%, 20.0%).

Renal Cell Carcinoma

Treatment-Naïve RCC

Study 3 (NCT#00083889) was a multi-center, international, randomized study comparing single-agent Sutent with IFN-α was conducted in patients with treatment-naïve RCC. The objective was to compare PFS in patients receiving Sutent versus patients receiving IFN-α. Other endpoints included ORR, OS, and safety. Seven hundred fifty (750) patients were randomized (1:1) to receive either 50 mg Sutent once daily on Schedule 4/2 or to receive IFN-α administered subcutaneously at 9 million international units (MIU) 3 times a week. Patients were treated until disease progression or withdrawal from the study.

The ITT population included 750 patients, 375 randomized to Sutent and 375 randomized to IFN-α. Demographics were comparable between the Sutent and IFN-α groups with regard to age (59% versus 67% <65 years for Sutent versus IFN-α, respectively), gender (male: 71% versus 72%), race (White: 94% versus 91%, Asian: 2% versus 3%, Black: 1% versus 2%, remainder not reported), and performance status (ECOG 0: 62% versus 61%, ECOG 1: 38% each arm, ECOG 2: 0 versus 1%). Prior treatment included nephrectomy (91% versus 89%) and radiotherapy (14% each arm). The most common site of metastases present at screening was the lung (78% versus 80%, respectively), followed by the lymph nodes (58% versus 53%, respectively) and bone (30% each arm); the majority of the patients had multiple (2 or more) metastatic sites at baseline (80% versus 77%, respectively).

There was a statistically significant advantage for Sutent over IFN-α in the endpoint of PFS (see Table 9and Figure 2). In the prespecified stratification factors of lactate dehydrogenase (LDH) (>1.5 ULN versus ≤1.5 ULN), ECOG performance status (0 versus 1), and prior nephrectomy (yes versus no), the hazard ratio favored Sutent over IFN-α. The ORR was higher in the Sutent arm (see Table 9).

At the protocol-specified final analysis of OS, the median OS was 114.6 weeks for the Sutent arm and 94.9 weeks for the IFN-α arm (HR=0.821; 95% CI: 0.673, 1.001). The median OS for the IFN-α arm includes 25 patients who discontinued IFN-α treatment because of disease progression and crossed over to treatment with Sutent as well as 121 patients (32%) on the IFN-α arm who received post-study cancer treatment with Sutent.

Cytokine-Refractory RCC

The use of single-agent Sutent in the treatment of cytokine-refractory RCC was investigated in 2 single-arm, multi-center studies. All patients enrolled into these studies experienced failure of prior cytokine-based therapy. In Study 4 (NCT#00077974), failure of prior cytokine therapy was based on radiographic evidence of disease progression defined by response evaluation criteria in solid tumors (RECIST) or World Health Organization (WHO) criteria during or within 9 months of completion of 1 cytokine therapy treatment (IFN-α, interleukin-2, or IFN-α plus interleukin-2; patients who were treated with IFN-α alone must have received treatment for at least 28 days). In Study 5 (NCT#00054886), failure of prior cytokine therapy was defined as disease progression or unacceptable treatment-related toxicity. The endpoint for both studies was ORR. Duration of response (DR) was also evaluated.

One hundred and six patients (106) were enrolled into Study 4 and 63 patients were enrolled into Study 5. Patients received 50 mg Sutent on Schedule 4/2. Therapy was continued until the patients met withdrawal criteria or had progressive disease. The baseline age, gender, race, and ECOG performance statuses of the patients were comparable between Studies 4 and 5. Approximately 86%–94% of patients in the 2 studies were White. Men comprised 65% of the pooled population. The median age was 57 years and ranged from 24 to 87 years in the studies. All patients had an ECOG performance status <2 at the screening visit.

The baseline malignancy and prior treatment history of the patients were comparable between Studies 4 and 5. Across the 2 studies, 95% of the pooled population of patients had at least some component of clear-cell histology. All patients in Study 4 were required to have a histological clear-cell component. Most patients enrolled in the studies (97% of the pooled population) had undergone nephrectomy; prior nephrectomy was required for patients enrolled in Study 4. All patients had received 1 previous cytokine regimen. Metastatic disease present at the time of study entry included lung metastases in 81% of patients. Liver metastases were more common in Study 4 (27% versus 16% in Study 5) and bone metastases were more common in Study 5 (51% versus 25% in Study 4); 52% of patients in the pooled population had at least 3 metastatic sites. Patients with known brain metastases or leptomeningeal disease were excluded from both studies.

The ORR and DR data from Studies 4 and 5 are provided in Table 10. There were 36 PRs in Study 4 as assessed by a core radiology laboratory for an ORR of 34.0% (95% CI: 25.0%, 43.8%). There were 23 PRs in Study 5 as assessed by the investigators for an ORR of 36.5% (95% CI: 24.7%, 49.6%). The majority (>90%) of objective disease responses were observed during the first 4 cycles; the latest reported response was observed in Cycle 10. DR data from Study 4 is premature as only 9 of 36 patients (25%) responding to treatment had experienced disease progression or died at the time of the data cutoff.

Adjuvant Treatment of RCC

In the adjuvant treatment setting, Sutent was investigated in S-TRAC (NCT#00375674), a multi-center, international, randomized, double-blind, placebo-controlled, trial in patients with high risk of recurrent RCC following nephrectomy. Patients were required to have clear cell histology and high risk of recurrence defined as ≥T3 and/or N+ tumors. Six hundred fifteen (615) patients were randomized 1:1 to receive either 50 mg Sutent once daily on Schedule 4/2 or placebo. Patients were treated for 9 cycles (approximately 1 year), or until disease recurrence, unacceptable toxicity, or withdrawal of consent.

Demographics were generally comparable between the Sutent and placebo arms with regard to age (median age 58 years), gender (73% male), and race (84% White, 12% Asian and 4% Other). At randomization, most patients had an ECOG performance status of 0 (74% Sutent and 72% placebo). The remainder of the patients had an ECOG performance status of 1; 1 patient on Sutent had a performance status of 2.

The major efficacy outcome measure was disease-free survival (DFS) in patients receiving Sutent versus placebo as assessed by blinded independent central review (BICR). Overall survival was an additional endpoint. There was a statistically significant improvement in DFS in patients who were treated with Sutent compared to placebo (Table 11 and Figure 3). Prespecified subgroup analyses are presented in Table 12. At the time of the DFS analysis, overall survival data were not mature, with 141/615 (23%) patient deaths.

Pancreatic Neuroendocrine Tumors

Study 6 (NCT#00428597) was a multi-center, international, randomized, double-blind, placebo-controlled study of single-agent Sutent conducted in patients with unresectable pNET. Patients were required to have documented RECIST-defined disease progression within the prior 12 months and were randomized (1:1) to receive either 37.5 mg Sutent (N=86) or placebo (N=85) once daily without a scheduled off-treatment period. The primary objective was to compare PFS in patients receiving Sutent versus patients receiving placebo. Other endpoints included OS, ORR, and safety. Use of somatostatin analogs was allowed in the study.

Demographics were comparable between the Sutent and placebo groups. Additionally, 49% of Sutent patients had nonfunctioning tumors vs 52% of placebo patients, and 92% patients in both arms had liver metastases. A total of 66% of Sutent patients received prior systemic therapy compared with 72% of placebo patients and 35% of Sutent patients had received somatostatin analogs compared with 38% of placebo patients. Patients were treated until disease progression or withdrawal from the study. Upon disease progression or study closure, patients were offered access to Sutent in a separate extension study.

As recommended by the Independent Data Monitoring Committee, the study was terminated prematurely prior to the prespecified interim analysis. This may have led to an overestimate of the magnitude of PFS effect. A clinically significant improvement for Sutent over placebo in PFS was seen by both investigator and independent assessment. A hazard ratio favoring Sutent was observed in all subgroups of baseline characteristics evaluated. OS data were not mature at the time of the analysis. There were 9 deaths in the Sutent arm and 21 deaths in the placebo arm. A statistically significant difference in ORR favoring Sutent over placebo was observed. Efficacy results are summarized in Table 13 and the Kaplan-Meier curve for PFS is in Figure 4.
