尿苷三乙酸口服颗粒剂
简介:2015年,美国食品药品监督管理局批准Xuriden上市。Xuriden是第一款由FDA准许的用于治疗遗传性乳清酸尿症的药物。遗传性乳清酸尿症是一种罕见的代谢紊乱疾病。

美国食品药品监督管理局批准Xuriden上市。Xuriden是第一款由FDA准许的用于治疗遗传性乳清酸尿症的药物。遗传性乳清酸尿症是一种罕见的代谢紊乱疾病,据报道全世界仅有20例左右的遗传性乳清酸尿症的患者。
遗传性乳清酸尿症经由人类隐性基因获得。该病主要是因为机体代谢中存在有错误或有缺陷的酶(乳清酸磷酸核糖转移酶和乳清酸核苷酸脱羧酶),从而导致机体不能够合成正常的尿苷(嘧啶类核苷酸),而尿苷是核糖核酸的重要组成部分。乳清酸不能转变为尿苷酸,就会导致血液和尿液中大量出现乳清酸。遗传性乳清酸尿症的主要标志和病症包括血液异常(贫血、白细胞数量减少、嗜中性粒细胞数量减少)、因乳清酸结晶形成物堵塞尿道引发的尿道堵塞、发育停滞和生长迟缓。在Xuriden被批准用药之前,治疗遗传性乳清酸尿症常用的方案是每天给予1到1.5g的尿嘧啶核苷。
FDA药物评估和研究中心的药物三期评估办公室负责人助理 Amy G. Egan说:“此次批准Xuriden的上市和罕见儿科疾病的优先审查制度均凸显了FDA保证罕见病患者能够获得有效治疗措施的决心。而在Xuriden被批准之前,患有罕见代谢紊乱疾病的病人并没有通过政府认可的可行治疗方案。”
FDA之所以批准Xuriden孤儿药的研发上市主要归因于其能够治疗罕见病。在美国,孤儿药的设计研发将会得到财政方面的激励,像临床试验税收抵免、使用者费用减免以及保证市场独占性资格等,这些措施无疑推动了孤儿药研发的进程。同样地,作为孤儿药的Xuriden 经批准也得到了优先审批。FDA的药物优先审批机制为某类严重疾病或特殊情况的治疗药物的加速审批提供了获得重大突破的便利之门。由于政府鼓励防治罕见儿童疾病治疗的新药和生物制品的研发,Xuriden的研发企业获得了罕见儿科病优先审批的“特权”。
Xuriden是一种旨在代替脲苷的口服类产品。Xuriden作为口服颗粒剂,可与食物、牛奶、婴儿配方奶粉等混合服用,每天口服一次即可。
为了评估Xuriden的安全性和有效性,相关专家对患有4名从3岁到19岁不等的遗传性乳清酸尿症患者进行了无对照的为期六周的开放性标记试验,并根据需要将试验周期延长到六个月之久。此次研究评估了患者在试验期间的各项血液学参数的变化情况。不管是六周还是六个月的评估,四位采用Xuriden进行治疗的遗传性乳清酸尿症患者的各项血液学参数均表现稳定。此项脲苷替代治疗方案已从发表公开的文献资料中得到了进一步的印证和支持。在长达九个月的试验中,服用Xuriden治疗的患者并未出现任何副作用。
批准日期:2015年9月4日 公司:Wellstat生物制药公司上市。

Warnings and PrecautionsNone.
Adverse ReactionsClinical Trials ExperienceBecause clinical trials are conducted under widely varying conditions and using a wide range of doses, 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 safety of Vistogard was assessed in 135 patients (median age 59 years, 56% male) treated in 2 single-arm, open-label, multi-center trials. Vistogard was administered at 10 grams orally every 6 hours for 20 doses or at a body surface area adjusted dosage of 6.2 grams/m2/dose for 20 doses in four patients between 1 and 7 years of age. The median duration of exposure was 4.8 days, with a median of 20 doses (range 1 to 23). Vistogard was discontinued for adverse reactions in two (1.4%) patients. Serious adverse reactions and Grade ≥3 adverse reactions were seen in one patient receiving Vistogard (Grade 3 nausea and vomiting). Table 2 summarizes the adverse reactions that occurred in greater than 2% of patients in Studies 1 and 2 combined.

Risk Summary
Limited case reports of uridine triacetate use during pregnancy are insufficient to inform a drug-associated risk of birth defects and miscarriage. When administered orally to pregnant rats during the period of organogenesis, uridine triacetate at doses of one-half the maximum recommended human dose (MRHD) of 40 grams per day was not teratogenic and did not produce adverse effects on embryo-fetal development [see Data].
The background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data
Animal Data
In an embryo-fetal development study, uridine triacetate was administered orally to pregnant rats during the period of organogenesis at doses up to 2000 mg/kg per day (about one-half the maximum recommended human dose (MRHD) of 40 grams per day on a body surface area basis). There was no evidence of teratogenicity or harm to the fetus and no effect on maternal body weight and overall health.
LactationRisk Summary
There are no data on the presence of uridine triacetate in human milk, the effect on the breastfed infant or the effect on milk production. The development and health benefits of breastfeeding should be considered along with the mother's clinical need for Vistogard and any potential adverse effects on the breastfed infant from Vistogard or from the underlying maternal condition.
Pediatric UseThe safety and effectiveness of Vistogard have been established in pediatric patients. Use of Vistogard in pediatric patients is supported by an open-label clinical study of adults (Study 1) and a second open-label clinical study which included 6 pediatric patients ranging in age from 1 to 16 years (Study 2). Four of these pediatric patients were between 1 to 7 years of age and received a body-surface area adjusted dosage of 6.2 grams/m2/dose for 20 doses. The clinical response and safety in adult and pediatric patients treated with Vistogard were similar; however, clinical data are limited [see Clinical Studies (14)].
Geriatric UseOf the 135 patients in clinical studies with Vistogard, 30% were 65 and over, including 11% that were 75 and over. Clinical studies of Vistogard did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
Vistogard DescriptionVistogard oral granules contain the active ingredient uridine triacetate which is a pyrimidine analog. The chemical name for uridine triacetate is (2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)-2,4(1H,3H)-pyrimidinedione. The molecular weight is 370.3 grams/mole and it has an empirical formula of C15H18N2O9. The structural formula is:
Each single-dose 10 gram packet of Vistogard orange-flavored oral granules (95% w/w) contains 10 grams of uridine triacetate and the following inactive ingredients: ethylcellulose (0.309 grams), Opadry® Clear [proprietary dispersion of hydroxypropylmethylcellulose and Macrogol] (0.077 grams), and natural orange juice flavor (0.131 grams).
Vistogard - Clinical PharmacologyMechanism of ActionUridine triacetate is an acetylated pro-drug of uridine. Following oral administration, uridine triacetate is deacetylated by nonspecific esterases present throughout the body, yielding uridine in the circulation. Uridine competitively inhibits cell damage and cell death caused by fluorouracil.
Fluorouracil is a cytotoxic antimetabolite that interferes with nucleic acid metabolism in normal and cancer cells. Cells anabolize fluorouracil to the cytotoxic intermediates 5-fluoro-2'-deoxyuridine-5'-monophosphate (FdUMP) and 5-fluorouridine triphosphate (FUTP). FdUMP inhibits thymidylate synthase, blocking thymidine synthesis. Thymidine is required for DNA replication and repair. Uridine is not found in DNA.
The second source of fluorouracil cytotoxicity is the incorporation of its metabolite, FUTP, into RNA. This incorporation of FUTP into RNA is proportional to systemic fluorouracil exposure. Excess circulating uridine derived from Vistogard is converted into uridine triphosphate (UTP), which competes with FUTP for incorporation into RNA.
PharmacokineticsAbsorption
Vistogard delivers 4- to 6-fold more uridine into the systemic circulation compared to equimolar doses of uridine itself. Maximum concentrations of uridine in plasma following oral Vistogard are generally achieved within 2 to 3 hours, and the half-life ranges from approximately 2 to 2.5 hours.
Studies 1 and 2 included an assessment of plasma uridine in a subgroup of patients who were overdosed with fluorouracil or experiencing early-onset of serious fluorouracil toxicities. Samples were obtained prior to Vistogard treatment and at 1 to 4 hours following the first and final doses of Vistogard given at 10 g (adults) or 6.2 grams/m2 (pediatric) every 6 hours for up to 20 doses. Plasma uridine concentrations are summarized in Table 3.

Food Effect on Uridine PK: A study in healthy adult subjects receiving a slightly different formulation of uridine triacetate granules (6 gram dose) under fed and fasted conditions showed no difference in the overall rate and extent of uridine exposure.
Distribution
Circulating uridine is taken up into mammalian cells via specific nucleoside transporters, and also crosses the blood brain barrier.
Excretion
Uridine can be excreted via the kidneys, but is also metabolized by normal pyrimidine catabolic pathways present in most tissues.
Drug Interaction Studies
In vitro enzyme inhibition data did not reveal meaningful inhibitory effects of uridine triacetate or uridine on CYP3A4, CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP2E1. In vitro enzyme induction data did not reveal an inducing effect of uridine triacetate or uridine on CYP1A2, CYP2B6, or CYP3A4.
In vitro data showed that uridine triacetate was a weak substrate for P-glycoprotein. Uridine triacetate inhibited the transport of a known P-glycoprotein substrate, digoxin, with an IC50 of 344 µM. Due to the potential for high local (gut) concentrations of the drug after dosing, the interaction of Vistogard with orally administered P-gp substrate drugs cannot be ruled out.
In vivo data in humans are not available.
Specific Populations
Sex
Pharmacokinetics analyses showed that sex did not have a significant effect on uridine pharmacokinetics.
Age
Pharmacokinetic analysis showed that within the age range evaluated (20 to 83 years), age did not have a significant effect on uridine pharmacokinetics.
Body Size
Pharmacokinetic analyses showed no clinically meaningful effect of body surface area on uridine PK in adults.
Nonclinical ToxicologyCarcinogenesis, Mutagenesis, Impairment of FertilityLong-term studies in animals have not been performed to evaluate the carcinogenic potential of uridine triacetate.
Uridine triacetate was not genotoxic in the Ames test, the mouse lymphoma assay and the mouse micronucleus test.
Orally administered uridine triacetate did not affect fertility or general reproductive performance in male and female rats at doses up to 2000 mg/kg per day (about one-half the maximum recommend human dose (MRHD) of 40 grams per day on a body surface area basis).
Animal Toxicology and/or PharmacologyIn mice given a sub-lethal dose of fluorouracil, the administration of oral uridine triacetate diminished hematological toxicity as a function of increasing dose, but did not completely prevent hematological toxicity. In mice given a lethal dose of fluorouracil, administration of oral uridine triacetate increased survival to 90% when given within 24 hours. Survival diminished with increasing interval between the fluorouracil dose and uridine triacetate treatment demonstrating that earlier administration of uridine triacetate is more beneficial. In similar experiments in mice, uridine triacetate treatment diminished damage to the intestinal mucosa caused by fluorouracil treatment.
Clinical StudiesThe efficacy of Vistogard was assessed in 135 patients who were treated in two open-label trials, Study 1 (n=60) and Study 2 (n=75). The patients in both studies had either received an overdose of fluorouracil or capecitabine, or presented with severe or life-threatening toxicities within 96 hours following the end of fluorouracil or capecitabine administration. Overdose was defined as administration of fluorouracil at a dose, or infusion rate, greater than the intended dose or maximum tolerated dose for the patient's intended regimen of fluorouracil. Vistogard was administered at 10 grams orally every 6 hours for 20 doses or at a body surface area adjusted dosage of 6.2 grams/m2/dose for 20 doses for four patients between 1 and 7 years of age. The major efficacy outcome was survival at 30 days or until the resumption of chemotherapy if prior to 30 days.
In Study 1 and Study 2 combined, the median age of the patients was 59 years (range: 1 to 83), 56% were male, 72% were white, 9% were Black/African American, 6% were Hispanic, 4% were Asian, and 95% had a cancer diagnosis. Of the 135 patients, 117 were treated with Vistogard following an overdose of fluorouracil (n=112) or capecitabine (n=5), and 18 were treated after exhibiting severe or life-threatening fluorouracil toxicities within 96 hours following the end of fluorouracil administration. The severe or life-threatening toxicities involved the central nervous system (such as encephalopathy, acute mental status change), cardiovascular system, gastrointestinal system (such as mucositis), and bone marrow. A total of six pediatric patients were administered Vistogard. Four patients initiated Vistogard more than 96 hours following the end of fluorouracil or capecitabine administration. Of the 112 patients overdosed with fluorouracil, 105 (94%) were overdosed by infusion rate only (range 1.3 to 720 times the planned infusion rate), four (4%) were overdosed by dose only, and three (3%) were overdosed by both dose and rate.
The survival results are shown in Table 4. Of the 135 patients who were treated with Vistogard in Studies 1 and 2 there were five deaths due to fluorouracil or capecitabine toxicity (4%). Of the five patients who died, two were treated after 96 hours following the end of fluorouracil administration. In the patients treated with Vistogard for an overdose of fluorouracil or capecitabine in Studies 1 and 2 combined (n=117), survival at 30 days was 97% (n=114). In the patients receiving Vistogard for early-onset severe or life-threatening toxicity in Studies 1 and 2 combined (n=18), the survival at 30 days was 89% (n=16). In these studies 33% of patients (n=45) resumed chemotherapy in less than 30 days. Based on retrospective historical case reports of 25 patients who were overdosed with fluorouracil and received supportive care only, all were overdosed by rate with a range 1.9 to 64 times the planned infusion rate, and 84% died.
