【孕妇及哺乳期妇女用药】
风险总结
根据其作用机制和动物中发现当给予妊娠妇女Lynparza可能致胎儿危害。在暴露低于接受推荐人剂量400 mg每天2次患者奥拉帕尼致畸胎性和在大鼠中致胚胎-胎儿毒性。如在妊娠期间使用药物,或如用药物时患者成为妊娠,忠告患者对胎儿潜在危害和对丢失妊娠潜在风险。
动物数据
在雌性大鼠一项生育力和早期胚胎发育研究中,在交配前至妊娠第6天口服给予奥拉帕尼,在剂量水平15 mg/kg/day(有母体全身暴露推荐剂量时人暴露(AUC0-24h)约11%时)导致植入后丢失增加。
在一项胚胎-胎儿发育研究,妊娠大鼠在器官形成期时接受口服剂量0.05和0.5 mg/kg/day奥拉帕尼。一个剂量0.5 mg/kg/day(有母体全身暴露推荐剂量人暴露(AUC0-24h)的约0.3%)致胚胎-胎儿毒性包括植入后丢失增加和眼重大畸形(无眼,小眼球),脊椎/肋骨(额外肋骨或骨化中心;融合或缺乏神经弓,肋骨,和胸骨),颅骨(融合的外枕)和横隔(疝)。另外异常或变异体包括不完全或缺乏骨化(脊椎/胸骨,肋骨,肢体)和在脊椎/胸骨,骨盆带,肺,胸腺,肝,输尿管和脐带动脉中其他发现。在剂量0.05 mg/kg/day 奥拉帕尼观察到低发生率的眼,肋骨和输尿管中上述某些发现。
哺乳母亲
不知道奥拉帕尼是否排泄在人乳汁中。因为许多药物被排泄在人乳汁和因为哺乳婴儿对严重不良反应来自奥拉帕尼潜能,应做出决定是否终止哺乳或终止药物,考虑药物对母亲的重要性。
【儿童用药】
尚未在儿童患者中确定Lynparza 的安全性和疗效。
【老年人用药】
在Lynparza的临床研究纳入735例有晚期实体肿瘤患者[其中多数(69%)有卵巢癌]接受Lynparza 400 mg每天2次作为单药治疗,148例(20%)患者是年龄 ≥65岁。不管除了CTCAE ≥3的不良反应被报道年龄≥65岁患者(53.4%)比<65 岁患者(43.4%)更频,没有个别不良事件或全身器官类型解释观察到差别,安全性图形相似。
【生殖潜能的女性 】
当给予至一例妊娠妇女Lynparza可致胎儿危害。忠告有生殖潜能女性患者当用Lynparza避免妊娠。如正在考虑避孕方法,用Lynparza治疗期间和对Lynparza末次剂量后至少1个月使用高效避孕避孕。指导患者如她们成为妊娠,或如用Lynparza时如怀疑妊娠 联系其卫生保健提供者。
【肝受损 】
尚未研究肝受损对暴露于Lynparza的影响。Lynparza临床试验排除有胆红素 >1.5 × ULN和AST/ALT ≥2.5 × ULN(肝转移的存在中≥5 × ULN)患者。没有有基线肝受损(血清胆红素 >1.5 × ULN) 患者数据[见临床药理学(12.3)]。
【肾受损】
根据初步数据,有轻度肾受损患者(CLcr = 50-80 mL/min)与有正常肾功能患者(CLcr >80 mL/min)比较观察到均数暴露(AUC) 增加1.5倍。有CLcr 50至80 mL/min患者对开始剂量无需剂量调整,但患者应被密切监视毒性。没有有中度或严重肾受损(CLcr <50 mL/min)患者或用透析患者的数据[见临床药理学(12.3)]。
【药理作用】
Lynparza是一种聚(ADP-核糖)聚合酶(PARP)酶抑制剂,包括 PARP1,PARP2,和PARP3。 PARP酶是涉及正常细胞动态平衡,例如DNA转录,细胞周期调节,和DNA修复。奥拉帕尼 在体外曾被显示抑制选择肿瘤细胞株生长和在人类的小鼠异种移植人癌模型减低肿瘤生长作为单药治疗或基于铂化疗后两方面。注意到用奥拉帕尼治疗后在细胞株中和有BRCA 缺陷的小鼠肿瘤模型增加细胞毒性和抗-肿瘤活性。体外研究已显示奥拉帕尼-诱导细胞毒性可能涉及PARP酶活性的抑制作用和PARP-DNA复合物形成增加,导致细胞动态平衡破坏和细胞死亡。
【药代动力学 】
吸收
奥拉帕尼通过胶囊制剂的口服给予后,迅速被吸收有峰血浆浓度典型地在给药后1至3小时间实现。用多次给药无明显积蓄(积蓄比值1.4 – 1.5对每天2次给药),3至4天内实现稳态暴露。
有限数据提示在跨越剂量范围100至400 mg,奥拉帕尼的全身暴露(AUC)的增加低于正比例但跨越试验PK数据是变异的。
与一种高脂肪餐共同给药显示吸收速率(Tmax延迟2小时),但不显著改变奥拉帕尼吸收的程度(均数AUC 增加约20%)。
分布
单次400 mg剂量奥拉帕尼后奥拉帕尼在稳态时有一个均数(±标准差)表观分布容积167 ± 196 L。在血浆浓度实现在400 mg每天2次给药后奥拉帕尼的体外蛋白结合是约82%。
代谢
在体外,CYP3A4被显示是主要负责奥拉帕尼代谢的酶。
口服给予14C-奥拉帕尼至女性患者后,未变化奥拉帕尼占血浆中循环放射性的多数(70%)。它被广泛地代谢在尿和粪中未变化药物放射性分别占15%和6%。代谢多数归咎于氧化反应与产生一些组分进行随后葡萄糖醛酸或硫酸结合。
排泄
单次400 mg剂量奥拉帕尼后观察到一个均数(±标准差)末端血浆半衰期11.9 ± 4.8小时和表观血浆清除率8.6 ± 7.1L/h。
单次剂量14C-奥拉帕尼后,在7天收集期间86%给予的放射性被回收,44%通过尿和42%通过粪。物料的多数作为代谢物被排泄。
根据来自专门致力肾受损试验初步数据,当奥拉帕尼被给予有轻度肾受损患者(CLcr = 50-80 mL/min; N=14)与有正常肾功能患者比较(CLcr >80 mL/min; N=8) 奥拉帕尼的均数AUC和Cmax分别增加1.5和1.2-倍。在有CLcr < 50 mL/min患者或在用透析患者没有数据。
【药物相互作用 】
在体外,奥拉帕尼是CYP3A4的一个抑制剂和在临床上实现的更高浓度是CYP2B6一种诱导剂。奥拉帕尼对其他CYP同工酶产生很小无抑制作用。体外研究曾显示奥拉帕尼是CYP3A4的底物。
根据来自一项药物-相互作用试验数据(N=57),当奥拉帕尼是与伊曲康唑,一种强CYP3A抑制剂联合给予时,奥拉帕尼的AUC和Cmax分别增加2.7-和1.4-倍。用基于生理学药代动力学 (PBPK)模型模拟提示一个中度CYP3A抑制剂(氟康唑)可增加奥拉帕尼的AUC和Cmax分别2-和1.1-倍。
根据来自一项药物-相互作用试验数据(N=22),当奥拉帕尼与利福平,一种强CYP3A 诱导剂联用给予时奥拉帕尼的AUC和Cmax减低分别87%和71%。用PBPK模型模拟提示一种中度CYP3A 诱导剂(依非韦伦)可能减低奥拉帕尼的AUC和Cmax分别50 - 60%和20 - 30%。
体外研究曾显示奥拉帕尼是P-gp的底物和BCRP,OATP1B1,OCT1,OCT2,OAT3,MATE1和MATE2K的抑制剂,不知道这些发现的临床相关。
奥拉帕尼是主要地被CYP3A代谢。
CYP3A抑制剂:避免同时使用强和中度CYP3A抑制剂。如不能避免抑制剂,减低剂量。(2.3,7.2)
CYP3A诱导剂:避免同时使用强和中度 CYP3A诱导剂。如中度CYP3A 诱导剂不能避免,被认识到减低疗效潜能。(7.3)
抗癌药
Lynparza临床研究与其他骨髓抑制抗癌药联用,包括DNA损伤药,表明加强和延长骨髓抑制毒性。
药物可能增加奥拉帕尼血浆浓度
在患者(N=57),伊曲康唑[itraconazole],一种强CYP3A抑制剂的共同给药,增加奥拉帕尼的AUC 2.7-倍。一种中度CYP3A抑制剂,氟康唑[fluconazole],预计增加奥拉帕尼的AUC 2-倍。
避免同时使用强CYP3A抑制剂(如,伊曲康唑,泰利霉素[telithromycin],克拉霉素[clarithromycin],酮康唑[ketoconazole],伏立康唑[voriconazole],奈法唑酮[nefazodone],泊沙康唑[posaconazole],利托那韦[ritinovir],洛匹那韦[lopinavir]/利托那韦,茚地那韦[indinavir],沙奎那韦[saquinavir],奈非那韦[nelfinavir],波普瑞韦[boceprevir],特拉匹韦[telaprevir])和中度CYP3A抑制剂(如,安普那韦[amprenavir],阿瑞吡坦[aprepitant],阿扎那韦[atazanavir],环丙沙星[ciprofloxacin],克唑替尼[crizotinib],达芦那韦[darunavir]/利托那韦,地尔硫卓[diltiazem],红霉素[erythromycin],氟康唑,福沙那韦[fosamprenavir],伊马替尼[imatinib],维拉帕米[verapamil])。如强或中度CYP3A抑制剂必须共同给药,减低Lynparza剂量[见剂量和给药方法(2.4)]。
Lynparza治疗期间避免避免柚子和塞维利亚橙子[见剂量和给药方法(2.4)和临床药理学(12.3)]。
可能减低奥拉帕尼血浆浓度药物
在患者(N=22)中,的共同给药利福平[rifampicin],一种强CYP3A诱导剂,减低奥拉帕尼AUC 87%。一种中度CYP3A诱导剂,依非韦伦[efavirenz],预计减低奥拉帕尼AUC 50-60%。
避免同时使用强CYP3A诱导剂(如,苯妥英钠[phenytoin],利福平,卡马西平[carbamazepine],圣约翰草)和中度CYP3A4诱导剂(如,波生坦[bosentan],依非韦伦,依曲韦林[etravirine],莫达非尼[modafinil],萘夫西林[nafcillin])。如避免一个中度CYP3A诱导剂,认识减低Lynparza疗效潜能[见临床药理学(12.3)]。
【非临床毒理学 】
未曾用奥拉帕尼进行致癌性研究。
奥拉帕尼在一项体外染色体试验在哺乳动物CHO细胞和在一项体内大鼠骨髓 微核试验是致染色体断裂。这个致染色体断裂性与这个致染色体断裂性与奥拉帕尼的主要药理学结果基因组不稳定性一致和表明对人中遗传毒性潜能。奥拉帕尼在细菌逆向突变(Ames)试验没有致突变性。
在一项生育力研究中,雌性大鼠接受口服奥拉帕尼在剂量0.05,0.5,和15 mg/kg/day共至少14天从交配前至妊娠的第一周,在剂量直至15 mg/kg/day(母体全身暴露在推荐剂量人暴露(AUC0-24h)约11%)对交配和生育力无不良影响。
在一项雄性生育力研究中,奥拉帕尼在大鼠口服剂量直至40 mg/kg/day(有全身暴露在推荐剂量人暴露(AUC0-24h)的约7%)至少70天奥拉帕尼治疗后对交配和生育力没有影响。
【贮藏】
贮存在25ºC,外出允许至15-30ºC。不应被暴露至温度大于40ºC。

FULL PRESCRIBING INFORMATION
1 INDICATIONS AND USAGE
1.1 Maintenance Treatment of Recurrent Ovarian Cancer Lynparza is indicated for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube or primary peritoneal cancer, who are in a complete or partial response to platinum-based chemotherapy.
1.2 Advanced gBRCA-mutated Ovarian Cancer After 3 or More Lines of Chemotherapy Lynparza is indicated for the treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm) advanced ovarian cancer who have been treated with three or more prior lines of chemotherapy. Select patients for therapy based on an FDA-approved companion diagnostic for Lynparza.
2 DOSAGE AND ADMINISTRATION
2.1 Important Administration Instructions Lynparza is also available as a 50 mg capsule. DO NOT substitute Lynparza tablets (100 mg and 150 mg) with Lynparza capsules (50 mg) on a milligram-to-milligram basis due to differences in the dosing and bioavailability of each formulation [see Clinical Pharmacology (12.3)]. Refer to the full prescribing information for Lynparza capsules for specific capsule dosing.
2.2 Recommended Dosing The recommended dose of Lynparza is 300 mg (two 150 mg tablets) taken orally twice daily, with or without food, for a total daily dose of 600 mg. The 100 mg tablet is available for dose reduction. Continue treatment until disease progression or unacceptable toxicity. If a patient misses a dose of Lynparza, instruct patient to take their next dose at its scheduled time. Swallow tablets whole. Do not chew, crush, dissolve, or divide tablet [see How Supplied/Storage and Handling (16.2)].
2.3 Patient Selection for gBRCA-mutated Advanced Ovarian Cancer Select patients for the treatment of advanced ovarian cancer with Lynparza based on the presence of deleterious or suspected deleterious BRCA-mutations [see Indications and Usage (1.2) and Clinical Studies (14.2)]. Information on FDA-approved tests for the detection of BRCA-mutations is available at http://www.fda.gov/companiondiagnostics.
2.4 Dose Adjustments for Adverse Reactions
To manage adverse reactions, consider interruption of treatment or dose reduction. 2 Reference ID: 4140621 The recommended dose reduction is to 250 mg (one 150 mg tablet and one 100 mg tablet) taken twice daily, for a total daily dose of 500 mg. If a further dose reduction is required, then reduce to 200 mg (two 100 mg tablets) taken twice daily, for a total daily dose of 400 mg.
2.5 Dose Modifications for Use with CYP3A Inhibitors Avoid concomitant use of strong or moderate CYP3A inhibitors and consider alternative agents with less CYP3A inhibition. If a strong CYP3A inhibitor must be co-administered, reduce the Lynparza dose to 100 mg (one 100 mg tablet) taken twice daily (equivalent to a total daily dose of 200 mg). If a moderate CYP3A inhibitor must be co-administered, reduce the Lynparza dose to 150 mg (one 150 mg tablet) taken twice daily (equivalent to a total daily dose of 300 mg) [see Drug Interactions (7.2) and Clinical Pharmacology (12.3)].
2.6 Dose Modifications for Patients with Renal Impairment Patients with mild renal impairment (CLcr 51-80 mL/min as estimated by Cockcroft-Gault equation) do not require an adjustment in Lynparza dosing. In patients with moderate renal impairment (CLcr 31-50 ml/min) the recommended dose reduction is to 200 mg (two 100 mg tablets) twice daily, for a total daily dose of 400 mg. The pharmacokinetics of Lynparza have not been evaluated in patients with severe renal impairment or end-stage renal disease (CLcr ≤30 mL/min) [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3)].

5 WARNINGS AND PRECAUTIONS
5.1 Myelodysplastic Syndrome/Acute Myeloid Leukemia Overall, the incidence of Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML) in patients treated with Lynparza monotherapy in clinical trials, including long-term follow up, was <1.5% (21/ 1680) and the majority of events had a fatal outcome. Of these, 19/21 patients had a documented BRCA mutation, 1 patient had gBRCA wildtype and in 1 patient the BRCA mutation status was unknown. Additional cases of MDS/AML have been documented in patients treated with Lynparza in combination studies. The duration of therapy with Lynparza in patients who developed secondary MDS/cancer-therapy related AML varied from < 6 months to > 2 years. All of these patients had received previous 3 Reference ID: 4140621 chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Some of these patients also had a history of previous cancer or bone marrow dysplasia. Do not start Lynparza until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt Lynparza and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Lynparza.
5.2 Pneumonitis Pneumonitis, including fatal cases, occurred in < 1% of patients treated with Lynparza. If patients present with new or worsening respiratory symptoms such as dyspnea, cough and fever, or a radiological abnormality occurs, interrupt Lynparza treatment and promptly assess the source of the symptoms. If pneumonitis is confirmed, discontinue Lynparza treatment and treat the patient appropriately.
5.3 Embryo-Fetal Toxicity
Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. In an animal reproduction study, administration of olaparib to pregnant rats during the period of organogenesis caused teratogenicity and embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 300 mg twice daily. Apprise pregnant women of the potential hazard to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of Lynparza [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].
6 ADVERSE REACTIONS
The following adverse reactions are discussed elsewhere in the labeling: •
Myelodysplastic Syndrome/Acute Myeloid Leukemia [see Warnings and Precautions (5.1)] • Pneumonitis [see Warnings and Precautions (5.2)]
6.1 Clinical Trial 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. Adverse reactions presented below were reported from clinical trials in 782 patients with ovarian cancer (555 received Lynparza, 227 received placebo). 4 Reference ID: 4140621
Maintenance Treatment of Recurrent Ovarian Cancer SOLO-2
The safety of Lynparza for the maintenance treatment of patients with platinum sensitive gBRCAm ovarian cancer was investigated in SOLO-2. This study was a placebo-controlled, double-blind study in which 294 patients received either Lynparza 300 mg (2 x 150 mg tablets) twice daily (n=195) or placebo tablets twice daily (n=99) until disease progression or unacceptable toxicity.
The median duration of study treatment was 19.4 months for patients who received Lynparza and 5.6 months for patients who received placebo. Dose interruptions due to an adverse reaction of any grade occurred in 45% of patients receiving Lynparza and 18% of those receiving placebo; dose reductions due to an adverse reaction occurred in 27% of Lynparza patients and 3% of placebo patients.
The most frequent adverse reactions leading to dose interruption or reduction of Lynparza were anemia (22%), neutropenia (9%), and fatigue/asthenia (8%). Discontinuation occurred in 11% of Lynparza patients and 2% in placebo patients. Table 1 summarizes the adverse reactions that occurred in at least 20% of patients who received Lynparza in SOLO-2.
Table 2 presents the laboratory abnormalities that occurred in at least 25 % of patients who received Lynparza in SOLO-2. 5 Reference ID: 4140621 Table 1 Adverse Reactionsa in SOLO-2 (≥20% of Patients who Received Lynparza) Adverse Reactions Lynparza tablets n=195 Placebo n=99 Grades 1-4 % Grades 3-4 % Grades 1-4 % Grades 3-4 % Blood and lymphatic disorders Anemiab 44 20 9 2 Gastrointestinal disorders Nausea 76 3 33 0 Vomiting 37 3 19 1 Diarrhea 33 2 22 0 Stomatitisc 20 1 16 0 Infections and Infestations Nasopharyngitis/ URI/ sinusitis/ rhinitis/ influenza 36 0 29 0 General disorders and administration site conditions Fatigue including asthenia 66 4 39 2 Metabolism and nutrition disorders Decreased appetite 22 0 11 0 Musculoskeletal and connective tissue disorder Arthralgia/myalgia 30 0 28 0 Nervous system disorders Dysgeusia 27 0 7 0 Headache 26 1 14 0 a Graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE ), version 4.0. b Represents grouped term consisting of anemia, hematocrit decreased, hemoglobin decreased, iron deficiency, mean cell volume increased and red blood cell count decreased. c Represents grouped term consisting of abscess oral, aphthous ulcer, gingival abscess, gingival disorder, gingival pain, gingivitis, mouth ulceration, mucosal infection, mucosal inflammation, oral candidiasis, oral discomfort, oral herpes, oral infection, oral mucosal erythema, oral pain, oropharyngeal discomfort, and oropharyngeal pain.

Study 19
The safety of Lynparza capsules as maintenance monotherapy was also evaluated in patients with platinum sensitive ovarian cancer who had received 2 or more previous platinum containing regimens in Study 19, a randomized, placebo-controlled, double-blind, multi-center study in which 264 patients received Lynparza 400 mg twice daily (n=136) or placebo (n=128). At the time of final analysis, the median duration of exposure was 8.7 months in patients who received Lynparza and 4.6 months in patients who received placebo. Adverse reactions led to dose interruptions in 35% of those receiving Lynparza and 10% of those receiving placebo; dose reductions in 26% of Lynparza and 4% of placebo; and discontinuation in 6% of Lynparza and 2% in placebo. Table 3 summarizes the adverse reactions that occurred in at least 20% of patients who received Lynparza in Study 19. Table 4 presents the laboratory abnormalities that occurred in at least 25% of patients from Study 19. 7 Reference ID: 4140621

Treatment of Advanced gBRCAm Ovarian Cancer After 3 or More Lines of Chemotherapy Pooled data Treatment with Lynparza (capsule formulation) as monotherapy was studied in 223 patients (pooled from 6 studies) with gBRCAm advanced ovarian cancer who had received 3 or more prior lines of 8 Reference ID: 4140621 chemotherapy.
Adverse reactions led to dose interruption in 40% of patients, dose reduction in 4% of patients, and discontinuation in 7% of patients. There were 8 (4%) patients with adverse reactions leading to death, two were attributed to acute leukemia, and one each was attributed to COPD, cerebrovascular accident, intestinal perforation, pulmonary embolism, sepsis, and suture rupture. The median exposure to Lynparza capsules in these patients was 5.2 months. Table 5 presents adverse reactions reported in ≥20% of patients and Table 6 presents laboratory abnormalities that occurred in at least 25% of patients from the pooled studies.

Immune System Disorders: Hypersensitivity (rash/dermatitis).
7 DRUG INTERACTIONS
7.1 Anticancer Agents
Clinical studies of Lynparza in combination with other myelosuppressive anticancer agents, including DNA damaging agents, indicate a potentiation and prolongation of myelosuppressive toxicity.
7.2 Drugs That May Increase Olaparib Plasma Concentrations
Olaparib is primarily metabolized by CYP3A. In patients (N=57), co-administration of itraconazole, a strong CYP3A inhibitor, increased AUC of olaparib by 170%. A moderate CYP3A inhibitor, fluconazole, is predicted to increase the AUC of olaparib by 121%. Avoid concomitant use of strong CYP3A inhibitors such as itraconazole, telithromycin, clarithromycin, ketoconazole, voriconazole, nefazodone, posaconazole, ritonavir, lopinavir/ritonavir, indinavir, saquinavir, nelfinavir, boceprevir, and telaprevir. Avoid use of moderate CYPA inhibitors such as amprenavir, aprepitant, atazanavir, ciprofloxacin, crizotinib, darunavir/ritonavir, diltiazem, erythromycin, fluconazole, fosamprenavir, imatinib, and verapamil. If the strong or moderate CYP3A inhibitors must be co-administered, reduce the dose of Lynparza [see Dosage and Administration (2.5)]. 10 Reference ID: 4140621 Avoid grapefruit, grapefruit juice, Seville oranges, and Seville orange juice during Lynparza treatment since they are CYP3A inhibitors [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3)].
7.3 Drugs That May Decrease Olaparib Plasma Concentrations
In patients (N=22), co-administration of rifampicin, a strong CYP3A inducer, decreased AUC of olaparib by 87%. A moderate CYP3A inducer, efavirenz, is predicted to decrease the AUC of olaparib by approximately 60%. Avoid concomitant use of strong CYP3A inducers such as phenytoin, rifampicin, carbamazepine, and St. John’s Wort. Avoid concomitant use of moderate CYP3A4 inducers such as bosentan, efavirenz, etravirine, modafinil, and nafcillin. If a moderate CYP3A inducer cannot be avoided, there is a potential for decreased efficacy of Lynparza [see Clinical Pharmacology (12.3)].
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action [see Clinical Pharmacology (12.1)], Lynparza can cause fetal harm when administered to a pregnant woman. There are no available data on Lynparza use in pregnant women to inform the drug associated risk. In an animal reproduction study, the administration of olaparib to pregnant rats during the period of organogenesis caused teratogenicity and embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 300 mg twice daily [see Data]. Apprise pregnant women of the potential hazard to the fetus and the potential risk for loss of the pregnancy. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. The estimated background risk in the U.S. general population of major birth defects is 2-4%; and the risk for spontaneous abortion is approximately 15-20% in clinically-recognized pregnancies. Data Animal Data In a fertility and early embryonic development study in female rats, olaparib was administered orally for 14 days before mating through to day 6 of pregnancy, which resulted in increased post-implantation loss at a dose level of 15 mg/kg/day (with maternal systemic exposures approximately 7% of the human exposure (AUC0-24h) at the recommended dose). In an embryo-fetal development study, pregnant rats received oral doses of 0.05 and 0.5 mg/kg/day olaparib during the period of organogenesis. A dose of 0.5 mg/kg/day (with maternal systemic exposures approximately 0.18% of human exposure (AUC0-24h) at the recommended dose) caused embryo-fetal toxicities including increased post-implantation loss and major malformations of the eyes (anophthalmia, microphthalmia), vertebrae/ribs (extra rib or ossification center; fused or absent neural arches, ribs, and sternebrae), skull (fused exoccipital) and diaphragm (hernia). Additional abnormalities or variants 11 Reference ID: 4140621 included incomplete or absent ossification (vertebrae/sternebrae, ribs, limbs) and other findings in the vertebrae/sternebrae, pelvic girdle, lung, thymus, liver, ureter and umbilical artery. Some findings noted above in the eyes, ribs and ureter were observed at a dose of 0.05 mg/kg/day olaparib at lower incidence.
8.2 Lactation Risk Summary
No data are available regarding the presence of olaparib in human milk, or on its effects on the breastfed infant or on milk production. Because of the potential for serious adverse reactions in the breastfed infants from Lynparza, advise a lactating woman not to breastfeed during treatment with Lynparza and for one month after receiving the last dose.
8.3 Females and Males of Reproductive Potential
Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential prior to initiating treatment with Lynparza. Contraception Females Lynparza can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with Lynparza and for at least 6 months following the last dose.
8.4 Pediatric Use
The safety and efficacy of Lynparza have not been established in pediatric patients.
8.5 Geriatric Use
In clinical studies of Lynparza enrolling 482 patients with advanced solid tumors who received Lynparza tablets 300 mg twice daily as monotherapy, 135 (28%) patients were aged ≥65 years. There appeared to be no major difference in the safety profile of patients treated with olaparib aged <65 years versus ≥65 years, nor within the age categories of 65 to 74 years, 75 to 84 years. No patients were aged ≥85 years.
8.6 Hepatic Impairment
No adjustment to the starting dose is required in patients with mild hepatic impairment. A 15% increase in mean exposure (AUC) was observed in patients with mild hepatic impairment (based on Child-Pugh classification A) compared to patients with normal hepatic function. There are no data in patients with moderate or severe hepatic impairment [see Clinical Pharmacology (12.3)].
8.7 Renal Impairment
No adjustment to the starting dose is required in patients with mild renal impairment, but patients should be monitored closely for toxicity. A 24% increase in mean exposure (AUC) was observed in patients with mild renal impairment (CLcr = 51-80 mL/min) compared to patients with normal renal function (CLcr 12 Reference ID: 4140621 >80 mL/min). A 44% increase in AUC was observed in patients with moderate renal impairment (CLcr 31-50 mL/min) compared to patients with normal renal function (CLcr >80 mL/min). For patients with moderate renal impairment, reduce the dose of Lynparza to 200 mg twice daily [see Dosage and Administration (2.6)]. There are no data in patients with severe renal impairment or end-stage disease (CLcr ≤30 mL/min) [see Clinical Pharmacology (12.3)].
10 OVERDOSAGE
There is no specific treatment in the event of Lynparza overdose, and symptoms of overdose are not established. In the event of an overdose, physicians should follow general supportive measures and should treat the patient symptomatically.
11 DESCRIPTION
Olaparib is an inhibitor of the mammalian polyadenosine 5’-diphosphoribose polymerase (PARP) enzyme. The chemical name is 4-[(3-{[4-(cyclopropylcarbonyl)piperazin-1-yl]carbonyl}-4 fluorophenyl)methyl]phthalazin-1(2H)-one and it has the following chemical structure: The empirical molecular formula for Lynparza is C24H23FN4O3 and the relative molecular mass is 434.46. Olaparib is a crystalline solid, is non-chiral and shows pH-independent low solubility across the physiological pH range.
Lynparza tablets for oral administration contain 100 mg or 150 mg of olaparib.
Inactive ingredients in the tablet core are copovidone, mannitol, colloidal silicon dioxide and sodium stearyl fumarate. The tablet coating consists of hypromellose, polyethylene glycol 400, titanium dioxide, ferric oxide yellow and ferrosoferric oxide (150 mg tablet only). 13 Reference ID: 4140621
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Lynparza is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP1, PARP2, and PARP3. PARP enzymes are involved in normal cellular functions, such as DNA transcription and DNA repair.
Olaparib has been shown to inhibit growth of select tumor cell lines in vitro and decrease tumor growth in mouse xenograft models of human cancer, both as monotherapy or following platinumbased chemotherapy. Increased cytotoxicity and anti-tumor activity following treatment with olaparib were noted in cell lines and mouse tumor models with deficiencies in BRCA and non-BRCA proteins involved in the homologous recombination repair (HRR) of DNA damage and correlated with platinum response.
In vitro studies have shown that olaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage and cancer cell death.
12.2 Pharmacodynamics
Cardiac Electrophysiology
The effect of olaparib on cardiac repolarization was assessed in 119 patients following a single dose of 300 mg and in 109 patients following multiple dosing of 300 mg twice daily. No clinically relevant effect of olaparib on QT interval was observed.
12.3 Pharmacokinetics
Lynparza is available as a tablet and capsule formulation.
The oral bioavailability of the tablet formulation is higher than the capsule formulation. Population pharmacokinetic analyses have shown that the steady state exposure (AUC) following 300 mg tablet twice daily was 77% higher compared to that following 400 mg capsule twice daily. The olaparib geometric mean AUC and Cmax following a single 300 mg tablet dose were 42.0 μg*h/mL (n=204) and 5.8 μg/mL (n=204), respectively, and the steady state geometric mean AUC and Cmax following 300 mg tablet twice daily were 49.0 μg*h/mL (n=227) and 7.7 μg/mL (n=227), respectively. Olaparib showed time-dependent PK that the steady state clearance decreased by 15% after multiple dosing. Absorption Following oral administration of olaparib, absorption is rapid with median peak plasma concentrations typically achieved 1.5 hours after dosing. An AUC mean accumulation ratio of 1.8 is observed at steady state following multiple dosing of 300 mg tablets twice daily. Systemic exposure (single dose AUC) to olaparib increases approximately proportionally with doses over the dose range of 25 mg to 450 mg, Cmax increased slightly less than proportionally for the same dose range. Co-administration of a high fat meal with olaparib slowed the rate (tmax delayed by 2.5 hours) of absorption, but did not significantly alter the extent of olaparib absorption (mean AUC increased by approximately 8%).
14 Reference ID: 4140621
Distribution Olaparib had a mean (± standard deviation) apparent volume of distribution of 158 ± 136 L after a single 300 mg dose of olaparib. The in vitro protein binding of olaparib is approximately 82%. Metabolism In vitro, CYP3A4/5 were shown to be the enzymes primarily responsible for the metabolism of olaparib. Following oral dosing of 14C-olaparib to female patients, unchanged olaparib accounted for the majority of the circulating radioactivity in plasma (70%). It was extensively metabolized with unchanged drug accounting for 15% and 6% of radioactivity in urine and feces, respectively. The majority of the metabolism is attributable to oxidation reactions with a number of the components produced undergoing subsequent glucuronide or sulfate conjugation. Excretion A mean (± standard deviation) terminal plasma half-life of 14.9 ± 8.2 hours and apparent plasma clearance of 7.4 ± 3.9 L/h were observed after a single 300 mg dose of olaparib. Following a single dose of 14C-olaparib, 86% of the dosed radioactivity was recovered within a 7-day collection period, 44% via the urine and 42% via the feces. The majority of the material was excreted as metabolites. Drug Interactions Based on the data from a drug-interaction trial (N=57), the AUC and Cmax of olaparib increased by 170% and 42%, respectively, when olaparib was administered in combination with itraconazole, a strong CYP3A inhibitor.
Simulations suggested that a moderate CYP3A inhibitor (fluconazole) may increase the AUC and Cmax of olaparib by 121% and 14%, respectively. Based on the data from a drug-interaction trial (N=22), the AUC and Cmax of olaparib decreased by 87% and 71%, respectively, when olaparib was administered in combination with rifampicin, a strong CYP3A inducer. Simulations suggested that a moderate CYP3A inducer (efavirenz) may decrease the AUC and Cmax of olaparib by approximately 60% and 31%, respectively. In vitro studies have shown that olaparib is both an inhibitor and inducer of CYP3A and an inducer of CYP2B6. Olaprib is predicted to be a weak CYP3A inhibitor in humans. In vitro studies also indicated that olaparib is an inhibitor of UGT1A1, BCRP, OATP1B1, OCT1, OCT2, OAT3, MATE1 and MATE2K.
The clinical relevance of these findings is unknown. In vitro, olaparib is a substrate of, and inhibits, the efflux transporter P-gp. The potential for olaparib to induce P-gp has not been evaluated. Pharmacokinetics in Specific Populations Hepatic Impairment In a hepatic impairment trial, the mean AUC increased by 15% and the mean Cmax by 13% when olaparib was dosed in patients with mild hepatic impairment (Child-Pugh classification A; N=9) compared with 15 Reference ID: 4140621 patients with normal hepatic function (N=13).
Mild hepatic impairment had no effect on the protein binding of olaparib and therefore total plasma exposure was representative of free drug. There are no data in patients with moderate or severe hepatic impairment. Renal Impairment In a renal impairment trial, the mean AUC increased by 24% and Cmax by 15%, when olaparib was dosed in patients with mild renal impairment (CLcr = 51-80 mL/min defined by the Cockcroft-Gault equation; N=13) and by 44% and 26%, respectively, when olaparib was dosed in patients with moderate renal impairment (CLcr = 31-50 mL/min; N=13), compared to those with normal renal function (CLcr ≥81 mL/min; N=12). There was no evidence of a relationship between the extent of plasma protein binding of olaparib and creatinine clearance.
There are no data in patients with severe renal impairment or end-stage renal disease (CLcr ≤ 30 mL/min).
13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Carcinogenicity studies have not been conducted with olaparib. Olaparib was clastogenic in an in vitro chromosomal aberration assay in mammalian Chinese hamster ovary (CHO) cells and in an in vivo rat bone marrow micronucleus assay. This clastogenicity is consistent with genomic instability resulting from the primary pharmacology of olaparib and indicates potential for genotoxicity in humans.
Olaparib was not mutagenic in a bacterial reverse mutation (Ames) test.
In a fertility study, female rats received oral olaparib at doses of 0.05, 0.5, and 15 mg/kg/day for at least 14 days before mating through the first week of pregnancy. There were no adverse effects on mating and fertility rates at doses up to 15 mg/kg/day (maternal systemic exposures approximately 7% of the human exposure (AUC0-24h) at the recommended dose).
In a male fertility study, olaparib had no effect on mating and fertility in rats at oral doses up to 40 mg/kg/day following at least 70 days of olaparib treatment (with systemic exposures of approximately 5% of the human exposure (AUC0-24h) at the recommended dose).
14 CLINICAL STUDIES
14.1 Maintenance Treatment of Recurrent Ovarian Cancer The efficacy of Lynparza was investigated in two randomized, placebo-controlled, double-blind, multicenter studies in patients with recurrent ovarian cancers who were in response to platinum-based therapy.
SOLO-2 SOLO-2 (NCT01874353) was a double-blind, placebo-controlled trial in which patients (N=295) with germline BRCA-mutated (gBRCAm) ovarian, fallopian tube, or primary peritoneal cancer were randomized (2:1) to receive Lynparza tablets 300 mg orally twice daily or placebo until unacceptable toxicity or progressive disease. Randomization was stratified by response to last platinum chemotherapy (complete versus partial) and time to disease progression in the penultimate platinum-based chemotherapy 16 Reference ID: 4140621 prior to enrollment (6-12 months versus > 12 months).
All patients had received at least two prior platinum-containing regimens and were in response (complete or partial) to their most recent platinumbased regimen. All patients had a deleterious or suspected deleterious germline BRCA-mutation as detected either by a local test (n= 236) or central Myriad CLIA test (n=59), subsequently confirmed by BRAC Analysis CDx (n= 286).
The major efficacy outcome was investigator-assessed progression-free survival (PFS) evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1. Additional endpoints included overall survival (OS). The median age of patients treated with Lynparza was 56 years (range: 28 to 83) and 56 years (range: 39 to 78) among patients treated with placebo. ECOG performance score was 0 in 83% of patients receiving Lynparza and 78% of patients receiving placebo. Of all patients, 89% were White, 17% were enrolled in the U.S. or Canada, 47% were in complete response to their most recent platinum-based regimen, and 40% had a progression-free interval of 6-12 months since their penultimate platinum regimen. Prior bevacizumab therapy was reported for 17% of those treated with Lynparza and 20% of those receiving placebo.
Approximately 44% of patients on the Lynparza arm and 37% on placebo had received three or more lines of platinum-based treatment. SOLO-2 demonstrated a statistically significant improvement in investigator-assessed PFS in patients randomized to Lynparza as compared with placebo (Table 7 and Figure 1). Results from a blinded independent review were consistent.
At the time of the analysis of PFS, overall survival (OS) data were not mature with 24% of events.

Randomization was stratified by response to last platinum chemotherapy (CR versus PR), time to disease progression in the penultimate platinum-based chemotherapy (6-12 months versus > 12 months), and descent (Jewish versus non-Jewish). The major efficacy outcome measure of the study was investigator-assessed PFS evaluated according to RECIST, version 1.0. The median age of patients treated with Lynparza (n=136) was 58 years (range: 21 to 89) and 59 years (range 33 to 84) among patients treated with placebo (n=129).
ECOG performance status was 0 in 81% of patients receiving Lynparza and 74% of patients receiving placebo. Of all patients, 97% were White, 19% were enrolled in the US or Canada, 45% were in complete response following their most recent platinum chemotherapy regimen, and 40% had a progression-free interval of 6-12 months since their penultimate platinum.
Prior bevacizumab therapy was reported for 13% of patients receiving Lynparza and 16% of patients receiving placebo. A retrospective analysis for germline BRCA mutation status, some performed 18 Reference ID: 4140621 using the Myriad test, indicated that 36% (n=96) of patients from the ITT population had deleterious gBRCA mutation, including 39% (n=53) of patients on Lynparza and 33% (n=43) of patients on placebo. Study 19 demonstrated a statistically significant improvement in investigator-assessed PFS in patients treated with Lynparza versus placebo (Table 8 and Figure 2).

Study 19 14.2 Advanced gBRCA-mutated Ovarian Cancer Treated with 3 or More Prior Lines of Chemotherapy The efficacy of Lynparza was also investigated in a single-arm study of patients with deleterious or suspected deleterious gBRCAm advanced cancers. A total of 137 patients with measurable, advanced gBRCAm ovarian cancer treated with three or more prior lines of chemotherapy were enrolled. All patients received Lynparza capsules at a dose of 400 mg twice daily as monotherapy until disease progression or intolerable toxicity. Objective response rate (ORR) and duration of response (DOR) were assessed by the investigator according to RECIST, version 1.0. The median age of the patients was 58 years, the majority were White (94%) and 93% had an ECOG PS of 0 or 1. Deleterious or suspected deleterious gBRCAm status was verified retrospectively in 97% (59/61) of the patients for whom blood samples were available by the BRAC Analysis CDxTM. Efficacy results are summarized in Table 9. 20 Reference ID: 4140621

Lynparza may cause serious side effects, including: Bone marrow problems called Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML). Some people who have ovarian cancer and who have received previous treatment with chemotherapy, radiotherapy or certain other medicines for their cancer have developed MDS or AML during treatment with Lynparza. MDS or AML may lead to death. If you develop MDS or AML, your healthcare provider will stop treatment with Lynparza. Symptoms of low blood cell counts are common during treatment with Lynparza, but can be a sign of serious bone marrow problems, including MDS or AML.
Symptoms may include: • weakness • weight loss • fever • frequent infections • blood in urine or stool • shortness of breath • feeling very tired • bruising or bleeding more easily Your healthcare provider will do blood tests to check your blood cell counts: • before treatment with Lynparza • every month during treatment with Lynparza • weekly if you have low blood cell counts that last a long time. Your healthcare provider may stop treatment with Lynparza until your blood cell counts improve. Lung problems (pneumonitis).
Tell your healthcare provider if you have any new or worsening symptoms of lung problems, including shortness of breath, fever, cough, or wheezing. Your healthcare provider may do a chest x-ray if you have any of these symptoms. Your healthcare provider may temporarily stop treatment or completely stop treatment if you develop pneumonitis. Pneumonitis may lead to death.
