OPDIVO INTRAVENOUS INFUSION APPROVED IN JAPAN FOR TREATMENT OF UNRESECTABLE OR METASTATIC RCC

Ono Pharmaceutical and Bristol-Myers Squibb (BMS) announced that on August 26, 2016, Ono Pharmaceutical received approval for a partial change in approved items of the manufacturing and marketing authorization of Opdivo(R) (nivolumab) intravenous infusion (20 and 100 mg) for the treatment of unresectable or metastatic renal cell carcinoma (RCC) in Japan. Opdivo is a human anti-human programmed cell death protein 1 (PD-1) monoclonal antibody. This immune checkpoint inhibitor, which blocks the interaction of the PD-1 receptor with its ligands, is the first to demonstrate the extension of overall survival (OS) in patients with unresectable or metastatic RCC who have received prior antiangiogenic therapy. In the interim analysis of the open-label, randomized, phase III CheckMate-025 clinical trial (ClinicalTrials.gov Identifier NCT01668784), Opdivo demonstrated a median OS of 25 months versus 19.6 months for the active comparator everolimus, which offered a significant OS extension. In July 2014, Opdivo received manufacturing and marketing approval for treatment of unresectable melanoma in Japan, making it the first human anti-human PD-1 monoclonal antibody to be approved for this indication anywhere in the world. Opdivo also received additional approval for the indication of unresectable, advanced or recurrent non-small cell lung cancer in December 2015, and supplemental applications have been submitted for the indications of relapsed or refractory Hodgkin's lymphoma and recurrent or metastatic head and neck cancer. Outside of Japan, Opdivo has regulatory approval in 54 countries as part of the Ono and BMS collaboration. In Japan, Ono and BMS have formed a strategic partnership that includes codevelopment, co-commercialization and copromotion of multiple immunotherapies for patients with cancer in Japan. Ono hopes to gather further clinical data in order to ensure that Opdivo can be used more properly and effectively. In accordance with the conditional approval, Ono is committed to taking actions necessary for the proper use of Opdivo by implementing a postmarketing use-results survey (all-case surveillance) and collecting clinical data on the safety and efficacy of Opdivo (Ono Pharmaceutical News Release).

GUB09-145 EXERTS MARKED EFFECTS ON HBA1C, BODY WEIGHT AND GLUCOSE HOMESTASIS IN MICE

Investigators from Gubra ApS presented the results of a preclinical study on GUB09-145, a dual analogue of the insulinotropic hormone glucose-like peptide-1 (GLP-1) and the intestinotropic hormone GLP-2, to determine its potential as a Roux-en-Y gastric bypass (RYGB) mimetic to reduce body weight and improve glucose homeostasis. Results demonstrated a significant effect on food intake (24 h) in C57/BI6 mice after 1 week of q.d. or b.i.d. dosing GUB09-145 (t1/2 of 2.7 h), a result similar to that with liraglutide (t1/2 of 4.4 h). Additionally, administration of GUB09-145 (10 nmol s.c. b.i.d.; 50 nmol s.c. q.d.; and 50 nmol s.c. b.i.d.) for 1 week showed a marked effect on small intestine weight. In db/db mice, the co-agonist had a meaningful effect on body weight and body weight change compared to vehicle, from day 3 after the treatment, and at 50 nmol s.c. b.i.d., both GUB09-145 and liraglutide reduced food and water intake. In terms of glucose homeostasis, the candidate showed marked effects on fed blood glucose at days 10 and 20, with levels at < 10 nmol/L compared to > 10 and > 15 nmol/L for liraglutide and vehicle, respectively. HbA1c was also significantly reduced to approximately 5%. Both GUB09-145 and liraglutide reduced basal and glucose excursions during a terminal oral glucose tolerance test (OGTT), and neither of them caused any sustained effect on gastric emptying in db/db mice. The effects exerted by the long-acting co-agonist in these studies suggest the combination of insulinotrophic and intestinotrophic actions can be a promising strategy to treat obesity and diabetes (Jelsing, J. et al. 52nd Annu Meet Eur Assoc Study Diabetes (EASD) (Sept 12-16, Munich) 2016, Abst 787).

201695日,中国医学科学院发现新的FBPASE 1抑制剂

NEW CLASS OF FBPASE 1 INHIBITORS IDENTIFIED AT CHINESE ACADEMY OF MEDICAL SCIENCES

Scientists from the Chinese Academy of Medical Sciences have described their efforts in targeting fructose-1,6-bisphosphatase (FBPase 1) as a means of treating diabetes. To intervene in the gluconeogenesis pathway, novel indole derivate FBPase 1 inhibitors were synthesized, with a promising candidate identified:BJB-2936 (IC50 = 6.2 x 10[-8] M). Significant glucose lowering and HbA1c reduction was observed with BJB-2936 in diabetic mouse models (KKAgamma mice and db/db mice). Liver FBPase activity was reduced 40% and 98% by BJB-2936 doses of 50 and 200 mg/kg, respectively, in KKAgamma mice. Oral dosing of 200 mg/kg in rats was associated with a mean t1/2 of 3.26 h, mean tmax of 2.00 h, mean AUC0-t of 386.13 h*mcg/mL and a mean Cmax of 34.92 mcg/mL (Bie, J. et al. 24th Int Symp Med Chem (Aug 28-Sept 1, Manchester) 2016, Abst P448).

201696日,施贵宝发布有望成为抗凝血药物的新PAR-4抑制剂

近期在罗马结束的ESC会议和在曼彻斯特举行的第24EFMC 药物化学国际会议 (EFMC-ISMC 2016)上,施贵宝的研究者报告了新蛋白酶活化受体 4PAR-4)拮抗剂作为抗血小板治疗候选化合物的体外和体内数据。应用全血流式细胞分析对530例已知遗传背景的健康受试者进行检测,测量中等浓度PAR-4激动肽情况下的血小板活性。获得了个体间血小板对PAR-4激动肽的反应,个体PAR-4激动肽引起的血小板激活随着时间的推移保持一致。受试者开始试验后一年开始出现反应(高,中和低),在体外测量增加新PAR-4拮抗剂,UDM-002555的浓度对于抑制血小板激活的效果。结果显示UDM-002555PAR-4介导的血小板激活的抑制具有剂量依赖性,未发现无反应者。UDM-002555IC50值与不同反应者的血小板激活程度呈正相关,虽然程度中等。在高,中和低反应者中纤维蛋白原的IC50值分别为0.94, 0.67, 0.59 nMP-选择素为1.46, 1.211.06 nM 。总体来说,该研究结果未显示UDM-002555的效价和效力有显著的变化 (Downes, K. et al. ESC Congr (Aug 27-31, Rome) 2016, Abst P5000)
在电诱导颈动脉血栓形成(ECAT)模型和猴子中评估单剂量UDM-002555 (0.02, 0.1, 0.25, 0.5, 2.5 mg/kg) UDM-002555 (0.25 mg/kg)联合静脉阿司匹林(4 mg/kg/h)对抗凝血和出血时间(BT)的作用。体外研究中,UDM-002555在人和猴子中均可以抑制PAR-4激动肽诱导的血小板聚集,IC50值相近,分别为2.3 and 1 nM,这一发现支持在猴子中开展体内实验。2.5 mg/kg UDM-002555不能抑制PAR-1激动肽, ADP和胶原诱导的血小板聚集,不影响体外凝血时间,提示对PAR-4的选择性。在ECAT模型中,0.02, 0.1, 0.25, 0.5 2.5 mg/kgUDM-002555分别减少的血栓重量 (TW) 20, 25, 47, 48 51%。该候选化合物对稳态的影响有限,0.022.5 mg/kg剂量下对比空白对照仅分别提高1.6倍肾脏BT (KBT) 1.3倍肠系膜动脉BT (MBT)。最大抗血小板剂量的阿司匹林轻度减少9%TW,但是KBTMBT分别显著增加2.7倍和2.4倍。联合应用阿司匹林和UDM-002555减少64%TW且对比阿司匹林,不引起KBT MBT的额外增加(2.52.3) 。在同期的猴子研究中,标准抗血小板药物氯吡格雷 (0.3 mg/kg/day)减少49%TW ,但是分别增加KBTMBT7.48.1倍。这些结果显示在猴子中单用或联合阿司匹林,与标准抗血小板药物氯吡格雷和阿司匹林相比,UDM-002555的抗血栓作用有效,对稳态影响有限 数据提示PAR-4拮抗有望成为一种有潜力的新型抗血小板治疗选择。(Wong, P. et al.

BRISTOL-MYERS SQUIBB PRESENTS NOVEL PAR-4 ANTAGONISTS AS PROMISING ANTITHROMBOTIC AGENTS

At the recently concluded ESC Congress in Rome and the XXIV EFMC International Symposium on Medicinal Chemistry (EFMC-ISMC 2016) in Manchester, researchers from Bristol-Myers Squibb presented in vitro and in vivo data for novel proteinase-activated receptor 4 (PAR-4) antagonists being developed as antiplatelet therapy candidates.
Whole blood flow cytometric assays were used to measure platelet activity in response to a mid-range concentration of a PAR-4 agonist peptide in 530 healthy individuals whose genetic background is available. Inter-individual platelet responsiveness to the PAR-4 agonist peptide was established, and it was observed that platelet activation via PAR-4 agonist peptide within an individual was consistent over time. Subjects exhibiting a range of responses (hyper-, median- or hypo-responsive) were recalled approximately 1 year after initial testing, and the effectiveness of increasing concentrations of the novel PAR-4 antagonist, UDM-002555, to inhibit platelet activation in vitro was measured. The results revealed that UDM-002555 dose-dependently inhibited PAR-4-mediated platelet activation, with no nonresponders being identified. The UDM-002555 IC50 values demonstrated a positive, although modest, association with the extent of platelet activation between variable responders. The IC50 values in the hyper-, median- and hypo-responders were 0.94, 0.67, 0.59 nM for fibrinogen and 1.46, 1.21 and 1.06 nM for P-selectin, respectively. Overall, the results of the study do not indicate a significant shift in potency or efficacy of UDM-002555 (Downes, K. et al. ESC Congr (Aug 27-31, Rome) 2016, Abst P5000).
The antithrombotic and bleeding time (BT) effects of single oral dose of UDM-002555 (0.02, 0.1, 0.25, 0.5, 2.5 mg/kg) or UDM-002555 (0.25 mg/kg) in combination with intravenous aspirin (4 mg/kg/h) were evaluated in models of electrically mediated carotid artery thrombosis (ECAT) and in monkeys. In vitro, UDM-002555 inhibited platelet aggregation induced by PAR-4 agonist peptide in human and monkey blood with similar IC50 values of 2.3 and 1 nM, respectively, a finding that supported the use of monkeys for in vivo studies. UDM-002555 at 2.5 mg/kg did not inhibit platelet aggregation induced by PAR-1 agonist peptide, ADP and collagen, or affect ex vivo clotting times, which suggests PAR-4 selectivity. In the ECAT model, UDM-002555 at 0.02, 0.1, 0.25, 0.5 and 2.5 mg/kg reduced thrombus weight (TW) by 20, 25, 47, 48 and 51%, respectively. The drug candidate demonstrated a limited impact on hemostasis, with doses of 0.02 to 2.5 mg/kg leading to increases in BT in kidney (KBT) and mesenteric artery (MBT) by up to only 1.6-fold and 1.3-fold compared to vehicle, respectively. A maximum antiplatelet dose of aspirin slightly reduced TW by 9% but increased KBT and MBT significantly by 2.7- and 2.4-fold, respectively. Coadministration of aspirin and UDM-002555 reduced TW by 64% and did not cause additional increases in KBT and MBT (2.5- and 2.3-fold, respectively) over aspirin alone. In companion monkey studies, the standard of care antiplatelet agent clopidogrel (0.3 mg/kg/day) reduced TW by 49%, but increased KBT and MBT by 7.4- and 8.1-fold, respectively. These results demonstrated that UDM-002555 alone, or in combination with aspirin, provides effective antithrombotic activity with limited impact on homeostasis as compared to the standard antiplatelet agents, clopidogrel and aspirin, in monkeys. This data suggest that PAR-4 antagonism provides a potential, novel and promising antiplatelet therapeutic option (Wong, P. et al. ESC Congr (Aug 27-31, Rome) 2016, Abst P5001).
UDM-002555 has been described in the patent literature (WO 2013163279).
The discovery of the potent, selective and reversible small-molecule PAR-4 antagonist BMS-986120 was described at EFMC-ISMC 2016. BMS-986120 showed selectivity against PAR-4 (IC50 = 0.56), with no activity seen when evaluated against a panel of coagulation proteases and a broad panel of receptors, enzymes and ion channels. In vivo, the drug candidate demonstrated acceptable pharmacokinetic profile across species, with a half-life of 7.5, 27 and 27 hours, clearance of 2.6, 4.1 and 19 mL/min/kg, and oral bioavailability of 98, 19 and 29%, in rat, dog and cynomolgus monkey, respectively. In cynomolgus monkey thrombosis model, BMS-986120 showed strong dose-dependent antithrombotic efficacy as measured by blood flow and thrombus weight. Additionally, at the efficacious doses, BMS-986120 showed much lower bleeding liability than standard of care antiplatelet clopidogrel. BMS-986120 has recently advanced into human clinical studies (ClinicalTrials.gov Identifier NCT02208882; ClinicalTrials.gov Identifier NCT02439190) (Priestley, E.S. et al. 24th Int Symp Med Chem (Aug 28-Sept 1, Manchester) 2016, Abst LE033).

UNIVERSITY OF DUNDEE, GLAXOSMITHKLINE DEVELOP NOVEL COMPOUND FOR LEISHMANIASIS

The University of Dundee has collaborated with GlaxoSmithKline on the development of compounds for the potential treatment of visceral leishmaniasis. This disease is endemic in 88 countries with 350 million people at risk; there are 50,000 deaths a year and current treatments are inadequate. There is a need for low cost, oral, short course and safe medicine. Structure-activity-relationship work led to a compound showing an acceptable oral pharmacokinetic profile in mice with an > 95% parasite reduction seen at 50 mg/kg b.i.d. over 10 days. Due to a low solubility further compounds were sought, leading to DDD-85365, which was chosen for further development due to better linearity in pharmacokinetics and an acceptable therapeutic index. The compound showed in vivo efficacy of 6.0, with > 95% reduction in parasitemia at 25 mg/kg b.i.d. at 10 days. Its hERG IC50 value was > 30, with a CYP3A4 pIC50 value of <4.4. In rats there were no significant cardiovascular effects noted up to 1000 mg/kg. The compound is a kinase inhibitor, and work is ongoing to identify which kinases it targets (Thomas, M.G. et al. 24th Int Symp Med Chem (Aug 28-Sept 1, Manchester) 2016, Abst LE038)
DDD-85365 has been described in the patent literature (WO 2016116563).

FDA APPROVES ADALIMUMAB BIOSIMILAR AMJEVITA

The FDA has approved Amgen's Amjevita(TM) (adalimumab-atto) across all eligible indications of the reference product, Humira(R) (adalimumab). Amjevita is the first adalimumab biosimilar approved by the FDA and has been approved for the treatment of seven inflammatory diseases, including moderate to severe rheumatoid arthritis, moderate to severe polyarticular juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, moderate to severe chronic plaque psoriasis, adult moderate to severe Crohn's disease and moderate to severe ulcerative colitis. Approval was based on a comprehensive data package supporting biosimilarity to adalimumab based on analytical, nonclinical, pharmacokinetic and clinical data, including results from two phase III studies conducted in moderate to severe plaque psoriasis and moderate to severe rheumatoid arthritis. The phase III studies each met their primary endpoint showing clinical equivalence to adalimumab. Safety and immunogenicity of Amjevita were also comparable to adalimumab. Like Humira, the labeling for Amjevita contains a Boxed Warning regarding an increased risk of serious infections leading to hospitalization or death. The Boxed Warning also notes that lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers, including adalimumab products. Amgen's biosimilar adalimumab is also under review by the EMA, following its submission in December last year (Amgen News Release; FDA News Release).

FDA GRANTS ACCELERATED APPROVAL TO EXONDYS 51 FOR DUCHENNE MUSCULAR DYSTROPHY

The FDA has granted accelerated approval to Sarepta Therapeutics' Exondys 51(TM) (eteplirsen) as a once-weekly intravenous infusion of 30 mg/kg for the treatment of Duchenne muscular dystrophy (DMD) in patients who have a confirmed mutation in the DMD gene that is amenable to exon 51 skipping. A commercial launch will begin immediately. This indication is based on an increase in dystrophin in skeletal muscles observed in some patients treated with eteplirsen. A clinical benefit of eteplirsen has not been established. Continued approval for this indication may be contingent upon verification of a clinical benefit in confirmatory trials. The most common adverse reactions compared to a placebo group were vomiting (38%) and balance disorder (38%), with contusion, excoriation, arthralgia, rash, catheter site pain and upper respiratory tract infection also reported more frequently than placebo (10% or greater) (Sarepta Therapeutics News Release).

2016926日,FDA批准REXULTI关于精神分裂维持治疗的说明书更新

FDA批准了Rexulti(R) (brexpiprazole)的说明书更新,增加了精神分裂维持治疗的临床数据。批准基于一项在18-65岁成人精神分裂患者中进行的长期,随机,退出试验(ClinicalTrials.gov Identifier NCT01668797)的数据。Brexpiprazole治疗交叉滴定后,经过一个12-36brexpiprazole单盲稳定期,在稳定期内经brexpiprazole治疗连续12周症状稳定的患者随机分配进入双盲阶段,接受brexpiprazolen=97)或安慰剂(n=105)治疗。如果病人满足以下预先设定的标准,则认定在双盲阶段复发:根据PANSS CGI-I评分改变定义的症状加重,由于精神症状加重而住院,自杀行为或暴力/攻击性行为。在达到预设复发数后开展一次中期分析(为了减少持续安慰剂的治疗),结果显示与安慰剂相比,brexpiprazole组患者的到复发时间更长,具有统计学意义。该研究由于维持治疗的效果显现而提前终止。最终分析显示brexpiprazole组患者(1-4毫克/日)与安慰剂组患者相比,显著延长到复发时间。而且对于满足复发标准患者的比例这一主要次要终点, brexpiprazole治疗组也显著低于安慰剂组。Rexulti由大冢和Lundbeck共同开发,于去年7月在美国批准,作为抗抑郁药的辅助治疗用于成人重度抑郁症和成人精神分裂的治疗。公司期望向EMA递交MAA用于治疗成人精神分裂 (大冢制药新闻发布)

FDA APPROVES REXULTI LABELING UPDATE FOR MAINTENANCE TREATMENT OF SCHIZOPHRENIA

The FDA has approved a labeling update for Rexulti(R) (brexpiprazole) to include clinical data for maintenance treatment of schizophrenia. The approval was based on results from a long-term, randomized, withdrawal trial in adults with schizophrenia aged 18-65 years (ClinicalTrials.gov Identifier NCT01668797). After cross-titration from a prior antipsychotic to brexpiprazole, and a 12-36 week, single-blind brexpiprazole stabilization phase, patients who had been symptomatically stable on brexpiprazole for 12 consecutive weeks in the stabilization phase were randomized in a double-blind treatment phase to either brexpiprazole (n = 97) or placebo (n = 105). Impending relapse during the double-blind phase was determined if patients met any of the following pre-specified criteria: worsening symptoms defined by changes in PANSS or CGI-I scores, hospitalization for worsening psychotic symptoms, suicidal behavior, or violent/aggressive behavior. An interim analysis conducted after a pre-specified number of impending relapses (in order to minimize continued exposure to placebo) demonstrated a statistically significant longer time to relapse in patients randomized to brexpiprazole compared to placebo. The trial was subsequently terminated early because maintenance of efficacy had been demonstrated. The final analysis demonstrated a statistically significant longer time to relapse in patients randomized to brexpiprazole (1-4 mg/day) compared to placebo. The key secondary endpoint, the proportion of subjects who met the criteria for impending relapse, was statistically significantly lower in brexpiprazole-treated patients compared with placebo group. Rexulti, codeveloped by Otsuka and Lundbeck, was approved in the U.S. in July last year as an adjunctive therapy to antidepressants in adults with major depressive disorder and as a treatment in adults with schizophrenia. The companies anticipate submitting an MAA to the EMA for the use of brexpiprazole in the treatment of adult patients with schizophrenia (Otsuka Pharmaceutical News Release).

FDA APPROVES ORKAMBI FOR YOUNGER CYSTIC FIBROSIS POPULATION

The FDA has approved Vertex Pharmaceuticals' Orkambi(R) (lumacaftor/ivacaftor) for use in children with cystic fibrosis aged 6-11 years who have two copies of the F508del mutation. Orkambi is the first and only medicine to treat the underlying cause of cystic fibrosis for people with this mutation. It was previously approved by the FDA for use in people age 12 years and older with two copies of the F508del mutation. Orkambi will become available for children aged 6-11 years as soon as possible. Approval was based on data from an open-label phase III safety study. In the E.U., Vertex plans to submit an MAA variation in the first half of next year for children aged 6-11 years who have two copies of the F508del mutation. This application will be based on data from a phase III efficacy study with a primary endpoint of absolute change in lung clearance index (LCI). These data are expected before year-end (Vertex Pharmaceuticals News Release).
