Cyclosporine

LAVAL, Quebec, January 17, 2025 – Bausch Health Companies Inc. (NYSE:BHC)(TSX:BHC) and its gastroenterology (GI) business, Salix Pharmaceuticals, today acknowledged that the Centers for Medicare and Medicaid Services (CMS) has selected XIFAXAN® (rifaximin) 550 mg tablets as one of the medicines for the second round of negotiation as part of the Inflation Reduction Act with an initial price applicability in 2027 of the Drug Price Negotiation program. We look forward to engaging in open and transparent conversations with CMS, where we will share information on the value that XIFAXAN® delivers for the healthcare system in addition to sharing recommendations from The American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL) who gave XIFAXAN® the highest possible recommendation (Grade I, A,1) via their practice guidelines. We will continue to be driven by our commitment to patients in advocating for a healthcare environment that supports patient access to critical medications as well as encouraging future innovation. About XIFAXAN INDICATION XIFAXAN® (rifaximin) 550 mg tablets are indicated for the reduction in risk of overt hepatic encephalopathy (HE) recurrence in adults and for the treatment of irritable bowel syndrome with diarrhea (IBS-D) in adults. IMPORTANT SAFETY INFORMATION XIFAXAN is contraindicated in patients with a hypersensitivity to rifaximin, rifamycin antimicrobial agents, or any of the components in XIFAXAN. Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis. Clostridium difficile-associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including XIFAXAN, and may range in severity from mild diarrhea to fatal colitis. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. There is an increased systemic exposure in patients with severe (Child-Pugh Class C) hepatic impairment. Caution should be exercised when administering XIFAXAN to these patients. Caution should be exercised when concomitant use of XIFAXAN and P-glycoprotein (P-gp) and/or OATPs inhibitors is needed. Concomitant administration of cyclosporine, an inhibitor of P-gp and OATPs, significantly increased the systemic exposure of rifaximin. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P-gp inhibitors may further increase the systemic exposure to rifaximin. In clinical studies, the most common adverse reactions for XIFAXAN (alone or in combination with lactulose) were: HE (≥10%): Peripheral edema (17%), constipation (16%), nausea (15%), fatigue (14%), insomnia (14%), ascites (13%), dizziness (13%), urinary tract infection (12%), anemia (10%), and pruritus (10% IBS-D (≥2%): Nausea (3%), ALT increased (2%) INR changes have been reported in patients receiving rifaximin and warfarin concomitantly. Monitor INR and prothrombin time. Dose adjustment of warfarin may be required. XIFAXAN may cause fetal harm. Advise pregnant women of the potential risk to a fetus. HE (≥10%): Peripheral edema (17%), constipation (16%), nausea (15%), fatigue (14%), insomnia (14%), ascites (13%), dizziness (13%), urinary tract infection (12%), anemia (10%), and pruritus (10% IBS-D (≥2%): Nausea (3%), ALT increased (2%) To report SUSPECTED ADVERSE REACTIONS, contact Salix Pharmaceuticals at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

▎Armstrong 2025年1月10日，天广实生物宣布将APRIL抗体MIL116的相关专利和技术，以及大中华区外全球权益授权给Climb Bio，后者支付最高不超过8.93亿美元的首付款、开发和销售里程碑款，以及一定比例的销售分成。其中，预付款为900万美元，开发里程碑5175万美元，销售里程碑8.32亿美元。 2024年10月，大冢制药宣布APRIL抗体Sebeprenlimab治疗IgA肾病的三期临床VISIONARY达到预设主要终点，标志着APRIL靶点在IgA肾病完成临床概念验证。MIL116为天广实生物自主研发的APRIL抗体，目前处于临床前阶段。MIL116基于独特的分子设计和抗体工厂改造，可以更有效地促进APRIL的阻断与降解，有望实现更迅速、更深度、更持久的抑制APRIL信号传导，此外，MIL116经过长效化抗体工程改造，显著延长半衰期，有望进一步降低给药频率，改善患者依从性。 值得注意的是，同一天天广实生物还宣布了新型第三代CD20抗体MIL62治疗原发性膜性肾病的三期临床在其中分析获得阳性结果。154例患者按1:1随机分组接受MIL62或环孢素治疗，第52周MIL62治疗组完全缓解率显著优于环孢素对照组。 总结 IgA肾病和原发性膜性肾病属于最主要的免疫性肾病适应症，存在严重的未满足临床需求，天广实生物CD20抗体在原发性膜性肾病的三期临床中期分析取得成功，具有IgA肾病治疗潜力的APRIL抗体也完成授权出海，有望加速海外临床开发节奏。这两项进展进一步奠定了天广实生物在免疫性肾病领域的优势地位。 Armstrong技术全梳理系列 GPRC5D靶点全梳理； CD40靶点全梳理； CD47靶点全梳理； 补体靶向药物技术全梳理； 补体药物：眼科治疗的重要方向； Claudin 6靶点全梳理； Claudin 18.2靶点全梳理； 靶点冷暖，行业自知； 中国大分子新药研发格局； 被炮轰的“me too”； 佐剂百年史； 胰岛素百年传奇； CUSBEA：风雨四十载； 中国新药研发的焦虑； 中国生物医药企业的研发竞争； 中国双抗竞争格局； 中国ADC竞争格局； 中国双抗技术全梳理； 中国ADC技术全梳理； Ambrx技术全梳理； Vir Biotech技术全梳理； Immune-Onc技术全梳理； 亘喜生物技术全梳理； 康哲药业技术全梳理； 科济药业技术全梳理； 恺佧生物技术全梳理； 同宜医药技术全梳理； 百奥赛图技术全梳理； 腾盛博药技术全梳理； 创胜集团技术全梳理； 永泰生物技术全梳理； 中国抗体技术全梳理； 德琪医药技术全梳理； 德琪医药技术全梳理2.0； 和铂医药技术全梳理； 荣昌生物技术全梳理； 再鼎医药技术全梳理； 药明生物技术全梳理； 恒瑞医药技术全梳理； 豪森药业技术全梳理； 正大天晴技术全梳理； 吉凯基因技术全梳理； 基石药业技术全梳理； 百济神州技术全梳理； 百济神州技术全梳理第2版； 信达生物技术全梳理； 信达生物技术全梳理第2版； 中山康方技术全梳理； 复宏汉霖技术全梳理； 先声药业技术全梳理； 君实生物技术全梳理； 嘉和生物技术全梳理； 志道生物技术全梳理； 道尔生物技术全梳理； 尚健生物技术全梳理； 康宁杰瑞技术全梳理； 科望医药技术全梳理； 科望医药技术全梳理2.0； 岸迈生物技术全梳理； 礼进生物技术全梳理； 康桥资本技术全梳理； 余国良的抗体药布局； 荃信生物技术全梳理； 安源医药技术全梳理； 三生国健技术全梳理； 仁会生物技术全梳理； 乐普生物技术全梳理； 同润生物技术全梳理； 宜明昂科技术全梳理； 派格生物技术全梳理； 迈威生物技术全梳理； Momenta技术全梳理； NGM技术全梳理； 普米斯生物技术全梳理； 普米斯生物技术全梳理2.0； 三叶草生物技术全梳理； 贝达药业抗体药全梳理； 泽璟制药抗体药全梳理； 恒瑞医药抗体药全梳理； 齐鲁制药抗体药全梳理； 石药集团抗体药全梳理； 豪森药业抗体药全梳理； 华海药业抗体药全梳理； 科伦药业抗体药全梳理； 百奥泰技术全梳理； 凡恩世技术全梳理。
