Doxepin hydrochloride

5 月 27 日，卫材药业宣布，「莱博雷生片」（商品名：达卫眠）在中国获批上市，用于治疗成人失眠。值得一提的是，莱博雷生是国内首款获批上市的双重食欲素受体拮抗剂，其获批意味着国内失眠患者迎来了全新机制的新疗法。截图来源：企业官微莱博雷生由卫材药业研发，通过竞争性结合两种食欲素受体亚型（OX1R 和 OX2R），抑制食欲素神经传递，调节睡眠-觉醒节律。莱博雷生对 OX2R 具有更强的抑制作用，可抑制快速眼动睡眠（REM）和非 REM 睡眠驱动，实现更快的睡眠开始和更好的睡眠维持。据 Insight 数据库显示，该药最早于 2019 年 12 月在美国获批上市，商品名为 Dayvigo。目前，已经在超过 15 个国家和地区获批上市，包括日本、加拿大、澳大利亚等。在中国，2021 年度莱博雷生率先在中国香港和中国台湾上市，中国内地的首项上市申请则在 2024 年 1 月正式获 CDE 受理。但在本次获批之前，得益于「港澳药械通」政策，莱博雷生片得以新增进第四批粤港澳大湾区内地临床急需进口港澳药品医疗器械目录，从而可在指定医疗机构开具处方。在本次获批之后，更大范围的中国患者将受惠于此款新疗法。项目开发关键节点截图来自：Insight 数据库网页版，下同目前，莱博雷生在中国内地和中国台湾开展的 III 期临床试验（NCT04549168/CTR20190248）尚未公布结果，不过两项 III 期全球临床 SUNRISE 1（NCT02783729）和 SUNRISE 2（NCT02952820）都已有结果发布。SUNRISE 2 是一项为期 12 个月的随机、双盲、平行全球多中心 III 期研究，包括 6 个月的安慰剂对照期和随后 6 个月的积极治疗期。试验共纳入 949 名成人失眠患者，随机接受安慰剂或莱博雷生（5mg 或 10mg）。结果显示，与安慰剂相比，莱博雷生组患者报告的入睡潜伏期和入睡后主观觉醒时间均从基线减少，而主观睡眠效率从基线增加。具体而言，5mg 莱博雷生使患者主观睡眠开始潜伏期（sSOL）减少了 26.8 分钟，10mg 组患者减少了 32.1 分钟，而安慰剂组仅减少 17.5 分钟。在次要终点主观总睡眠时间（sTST）上，5mg、10mg 莱博雷生分别为 81.2 分钟、93.2 分钟，而安慰剂组仅为 74.8 分钟。SUNRISE 2 研究结果国内失眠人群庞大，中国睡眠数据报告统计，2025 年，中国有超过 5 亿人存在睡眠困扰。然而，目前的治疗药物主要以苯二氮卓类镇静催眠药（地西泮、艾司唑仑等）、非苯二氮卓类镇静催眠药（唑吡坦、扎来普隆等）、褪黑素受体激动剂（如雷美替胺、阿戈美拉汀）和具有催眠效应的抗抑郁药物（如多塞平、氟伏沙明）。然而这些药物多为老药，且存在耐药性、药物依赖性、反弹性失眠等问题。食欲素受体拮抗剂作为一种全新机制，有望突破这些困难，为患者带来新治疗方案。Insight 数据库显示，在莱博雷生之后，爱可隆制药/先声药业的「达利雷生」、扬子江药业的「法赞雷生」也分别在去年 7 月、今年 1 月陆续提交了上市申请。识别微信二维码，可添加药时空小编请注明：姓名+研究方向！

BRENTWOOD, Tenn., March 11, 2025 /PRNewswire/ -- Currax Pharmaceuticals LLC ("Currax"), a specialty pharmaceutical company and manufacturer of the #1 branded oral weight loss medication CONTRAVE® (naltrexone HCl/bupropion HCl), today announced the publication of its Cardiovascular Health Outcomes Analysis (HOA) for CONTRAVE®/MYSIMBA® in Obesity Pillars, the official journal of the Obesity Medicine Association. This peer-reviewed study, based on electronic health record data from more than 24,600 patients followed for over 4.7 years, found no evidence of excess cardiovascular risk and no statistically significant difference in major adverse cardiovascular events (MACE) between CONTRAVE/MYSIMBA and the comparator drug. The study's publication provides important real-world evidence that further substantiates the cardiovascular safety profile of CONTRAVE/MYSIMBA building on findings from prior clinical trials, a systemic literature review, two published FDA Adverse Event Reporting System (FAERS) database studies, and over ten years of post-marketing safety surveillance. These results provide valuable insights to support regulatory and clinical decision-making in the treatment of obesity. "The publication of this analysis in Obesity Pillars underscores the utility of evaluating long-term cardiovascular outcomes in routine clinical practice," said Michael Kyle, M.D., SVP, Chief Medical Officer of Currax Pharmaceuticals. "The findings further substantiate the cardiovascular safety profile of CONTRAVE/MYSIMBA, aligning with previous clinical and observational studies." CONTRAVE, approved in the U.S. and marketed in Europe as MYSIMBA, has been studied extensively in both randomized clinical trials and observational settings. The latest analysis builds upon prior research, including the LIGHT trial, and complements the ongoing INFORMUS trial, a large-scale cardiovascular outcomes study, which now has enrolled more than 3,000 patients and is designed to meet regulatory post-marketing requirements to further characterize long-term cardiovascular safety. "Obesity is a serious chronic disease, and it's critical that healthcare professionals have access to rigorous, data-driven evidence when considering treatment options," said George Hampton, President and CEO of Currax Pharmaceuticals. "Currax continues to invest in clinical trials designed to increase the utility of Contrave for physicians treating obesity." The full study is available in Obesity Pillars: About Currax Pharmaceuticals LLC Currax Pharmaceuticals LLC is a specialty pharmaceutical business focused on tackling the #1 and #2 causes of preventable death in the United States, smoking and obesity.

Along with diet and exercise, CONTRAVE is a prescription weight-loss medicine that may help some adults with a BMI > 30 kg/m2 (obese) or with a BMI of > 27 kg/m2 (overweight) with at least one weight-related medical problem such as high blood pressure, high cholesterol, or type 2 diabetes, lose weight and keep the weight off. It is not known if CONTRAVE changes your risk of heart problems or stroke or of death due to heart problems or stroke. It is not known if CONTRAVE is safe and effective when taken with other prescription, over-the-counter, or herbal weight-loss products. CONTRAVE is not approved to treat depression or other mental illnesses, or to help people quit smoking (smoking cessation). IMPORTANT SAFETY INFORMATION CONTRAVE can cause serious side effects including: Suicidal thoughts or actions: One of the ingredients in CONTRAVE is bupropion. Bupropion has caused some people to have suicidal thoughts or actions or unusual changes in behavior, whether or not they are taking medicines used to treat depression. Bupropion may increase the risk of suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment. If you already have depression or other mental illnesses, taking bupropion may cause it to get worse, especially within the first few months of treatment. While taking CONTRAVE, you or your family members should pay close attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. This is very important when you start taking CONTRAVE or when your dose changes. Stop taking CONTRAVE and call a healthcare provider right away if you or your family members notice any of the following symptoms, especially if they are new, worse, or worry you: thoughts about suicide or dying; attempts to commit suicide; depression; anxiety; feeling agitated or restless; panic attacks; irritability; aggression, anger, or violence; acting on dangerous impulses; an extreme increase in activity and talking; other unusual changes in behavior or mood; trouble sleeping. CONTRAVE is not approved for use in children under the age of 18.

The risk of seizure is higher in people who take higher doses of CONTRAVE, have certain medical conditions, or take CONTRAVE with certain other medicines. Do not take any other medicines while you are taking CONTRAVE unless your healthcare provider has said it is okay to take them. If you have a seizure while taking CONTRAVE, stop taking CONTRAVE and call your healthcare provider right away. Risk of opioid overdose. Do not take large amounts of opioids, including opioid-containing medicines, such as heroin or prescription pain pills, to try to overcome the opioid-blocking effects of naltrexone. This can lead to serious injury, coma, or death.

Using opioids in the 7 to 10 days before you start taking CONTRAVE may cause you to suddenly have symptoms of opioid withdrawal when you take it. Sudden opioid withdrawal can be severe, and you may need to go to the hospital. Tell your healthcare provider you are taking CONTRAVE before a medical procedure or surgery. Severe allergic reactions. Stop taking CONTRAVE and call your healthcare provider or go to the nearest hospital emergency room right away if you have any of the following signs and symptoms of an allergic reaction: rash, itching, hives, fever, swollen lymph glands, painful sores in your mouth or around your eyes, swelling of your lips or tongue, chest pain, or trouble breathing.

Stop taking CONTRAVE and tell your healthcare provider if you have any of the following symptoms of liver problems: stomach area pain lasting more than a few days, dark urine, yellowing of the whites of your eyes, or tiredness. Your healthcare provider may need to stop treating you with CONTRAVE if you get signs or symptoms of a serious liver problem. Manic episodes. Bupropion can cause some people who were manic or depressed in the past to become manic or depressed again. Visual problems (angle-closure glaucoma). Signs and symptoms may include: eye pain, changes in vision, swelling or redness in or around the eye. Talk with your healthcare provider to find out if you are at risk for angle-closure glaucoma and to get treatment to prevent it if you are at risk.
