Glepaglutide

近期，全球多肽和寡核苷酸（TIDES）领域迎来系列进展。Zealand Pharma公司宣布向欧洲药品管理局（EMA）递交其多肽疗法glepaglutide的上市申请，用于治疗短肠综合征（SBS）成人患者。用于治疗真性红细胞增多症（PV）的多肽疗法rusfertide达3期临床试验终点，需放血治疗的患者比例显著降低。治疗胶质母细胞瘤（GBM）的C/EBPβ拮抗剂lucicebtide（ST101）获积极2期临床试验结果。Glepaglutide：向EMA提交上市申请Zealand Pharma公司宣布向EMA递交其长效胰高血糖素样肽-2（GLP-2）类似物glepaglutide的上市许可申请（MAA），用于治疗SBS成人患者。Glepaglutide是一种装于自动注射器中的液体产品，设计用于每周两次的皮下给药，旨在减少或消除SBS患者对肠外营养支持（PS）的需求。美国FDA已授予该疗法治疗SBS的孤儿药资格。该递交主要是基于随机双盲关键3期试验EASE-1的结果，并得到两项正在进行的长期扩展试验EASE-2和EASE-3的中期结果和机制试验EASE-4的结果支持。EASE-1研究中，与安慰剂相比，每周两次glepaglutide给药在第24周显著降低患者每周PS所需总液体体积（P=0.0039）。第24周时，每周两次接受glepaglutide治疗患者的PS液体体积较基线平均降低5.13公升/周。安慰剂治疗仅导致所需PS液体体积降低2.85公升/周。对于接受每周两次glepaglutide治疗的患者，14%的患者（n=5）实现不再需要PS辅助治疗，而安慰剂治疗患者均不能停用PS。Rusfertide：公布3期临床试验的新数据Protagonist Therapeutics公司与武田（Takeda）公布了3期研究VERIFY的积极新结果。该试验主要评估每周一次的rusfertide自我给药皮下注射，在那些标准治疗下仍血容量控制不佳且依赖放血疗法的真性红细胞增多症患者中的疗效与安全性。Rusfertide是一种潜在“first-in-class”的在研天然激素铁调素的多肽模拟物，已获得美国FDA的孤儿药资格和快速通道资格。此次公布的分析结果显示，该研究达到了其主要终点，rusfertide联合当前标准治疗在高危和低危PV患者中使临床缓解率较安慰剂联合当前标准治疗组患者翻倍（76.9%对比32.9%），显著降低需放血治疗的患者比例。所有关键次要终点也均达到统计学显著差异，包括rusfertide联合治疗组需放血治疗的患者比例显著下降（27%对比78%），保持血细胞比容水平低于45%的患者比例显著提升（62.6%对比14.4%），患者报告的结局也有所改善。此外，未报告任何与rusfertide相关的严重不良事件。EO4010：公布1/2期联合治疗试验数据Enterome公司公布了其在研免疫疗法EO4010的1/2期临床试验AUDREY的积极数据。该研究旨在评估EO4010联合纳武利尤单抗（nivolumab）±贝伐珠单抗（bevacizumab）治疗微卫星稳定（MSS）/错配修复功能正常（pMMR）转移性结直肠癌（mCRC）的效果。EO4010是一种由五种微生物衍生肽组成的疫苗，这些肽模拟了五种常见于结直肠癌患者的肿瘤相关抗原（TAA）——BIRC5、FOXM1、UBE2C、CDC20和KIF2C，旨在激活患者的肿瘤特异性CD8阳性T细胞，引导其识别并杀死表达这些抗原的癌细胞。此次公布的结果显示，EO4010显示出良好的安全性和耐受性。中位随访时间为15.4个月时，20名MSS/pMMR mCRC患者的12个月生存率为40%，中位生存时间为11.3个月。目前，患者的生存曲线已趋于平稳，34%（7/20）的患者仍存活。此外，80%接受EO4010联合纳武利尤单抗治疗的患者体内检测到针对肿瘤相关抗原的特异性免疫反应。这些积极结果支持进一步开发EO4010治疗结直肠癌的潜力。Lucicebtide：公布2期临床试验结果Sapience Therapeutics公司公布了其潜在“first-in-class”的C/EBPβ拮抗剂lucicebtide治疗胶质母细胞瘤的2期临床试验数据。Lucicebtide已获得美国FDA授予用于治疗复发性GBM的快速通道资格，以及美国FDA和欧盟委员会授予的孤儿药资格，用以治疗神经胶质瘤。此次公布的结果显示，lucicebtide作为单一疗法和与标准护理（SoC）联合使用具有良好的耐受性。截至2025年5月6日的数据，新确诊的GBM队列中，9名患者中有5名尚未出现疾病进展（10-24+个月），6名患者在数据截止时仍然存活；复发性GBM队列中，9名患者中有4名获得疾病控制，其中2名为部分缓解（PR），3名患者在数据截止时仍然存活。[212Pb]VMT-α-NET：公布1/2a期临床试验的中期数据Perspective Therapeutics公司公布了其候选多肽偶联核素疗法[212Pb]VMT-α-NET的1/2a期临床试验的最新中期数据。该研究旨在评估[212Pb]VMT-α-NET在表达SSTR2的不可切除/转移性神经内分泌瘤（NET）患者中的疗效和安全性，这些患者既往未接受过放射性药物治疗（RPT），并且放射学证据显示其肿瘤在入组前12个月内已发生疾病进展。截至2025年4月30日的数据，该疗法安全性良好，在接受至少一种治疗的总共42名患者中，没有观察到剂量限制性毒性，也没有因不良事件而停药。在队列2的7名患者中，有4名达到了研究者评估的客观缓解，其中3名缓解已确认并持续维持，1名需进一步确认；而在队列1和2的共计9名患者中，有7名在超过一年的随访期内保持无疾病进展。ARO-ALK7：启动1/2a期临床试验Arrowhead Pharmaceuticals公司宣布，其用于治疗肥胖的在研小干扰RNA（siRNA）疗法ARO-ALK7的1/2a期临床试验已为第一批受试者给药。ARO-ALK7旨在沉默脂肪细胞中ACVR1C基因的表达，以减少激活素受体样激酶7（ALK7）的产生，ALK7在调节脂肪组织能量稳态的通路中充当受体。在临床前研究中，ARO-ALK7抑制了脂肪组织中ALK7的表达，从而能在保留瘦肌肉的同时减少体重和脂肪质量。新闻稿指出，ARO-ALK7是首个进入临床研究、靶向脂肪组织中表达基因的RNA干扰（RNAi）治疗药物。SC-102：IND申请获得FDA许可星联肽生物宣布，其EphA2靶向多肽偶联药物（PDC）SC-102的IND申请获得了美国FDA许可，可开展临床试验评估SC-102治疗表达EphA2的晚期或转移性实体瘤患者的安全性和有效性。SC-102通过特异性结合表达EphA2的肿瘤细胞，释放毒性载荷，从而抑制肿瘤生长。EphA2在多种肿瘤细胞表面高表达，SC-102有望治疗包括卵巢癌、乳腺癌、胰腺癌在内的多种实体瘤。此前，SC-102已在中国获批开展临床试验，目前正处于剂量递增研究阶段。已有临床数据显示，SC-102初步展现出良好的疗效和安全性。参考资料：[1] Arrowhead Pharmaceuticals Initiates Phase 1/2a Study of ARO-ALK7 for the Treatment of Obesity.

COPENHAGEN, Denmark I June 2, 2025 I Zealand Pharma A/S (Nasdaq: ZEAL) (“Zealand”) (CVR-no. 20045078), a biotechnology company focused on the discovery and development of innovative peptide-based medicines, today announced the submission of a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for glepaglutide, a long-acting GLP-2 analog, for the treatment of adult patients with short bowel syndrome (SBS). The submission of the MAA to the EMA for glepaglutide administered twice weekly for the treatment of SBS is based on results from a pivotal Phase 3 trial (EASE-1), supported by interim results from two ongoing long-term extension trials (EASE-2 and EASE-3) and results from a mechanistic trial (EASE-4). “We are pleased to bring our potential best-in-class GLP-2 analog, glepaglutide, one step closer to patients in Europe living with short bowel syndrome with intestinal failure, who urgently need more effective and more convenient treatment options,” said David Kendall, MD, Chief Medical Officer of Zealand Pharma. “We believe that glepaglutide, administered twice weekly, offers meaningful potential to reduce both the burden of parenteral support and the inconvenience of daily dosing required with the only currently available GLP-2 therapy. Looking ahead, we expect to initiate the EASE-5 Phase 3 trial in the second half of the year to obtain further confirmatory safety and efficacy data on the twice weekly dosing regimen, supporting regulatory submission in the U.S.” About glepaglutide Glepaglutide is a long-acting GLP-2 analog in development as a potential treatment option for short bowel syndrome (SBS). Glepaglutide is developed as a liquid product in an autoinjector designed for subcutaneous administration by twice weekly dosing, aimed to reduce, or eliminate, the need for parenteral support in people living with SBS. The U.S. Food and Drug Administration (FDA) has granted orphan drug designation for glepaglutide for the treatment of SBS. About the EASE Clinical Trial Program The Phase 3 program, named EASE, is designed to evaluate the potential for glepaglutide to reduce or eliminate the need for parenteral support in SBS patients with intestinal failure. EASE-1 (NCT03690206) was a randomized, double-blind Phase 3 trial that enrolled a total of 106 SBS patients with intestinal failure who were dependent on parenteral support for at least three days per week. Patients were evenly randomized to receive treatment with 10 mg glepaglutide administered either once or twice weekly, or placebo. The primary endpoint in the trial was the absolute change in weekly parenteral support volume from baseline at 24 weeks. At 24 weeks, glepaglutide administered twice weekly significantly reduced the total weekly volume of PS by 5.13 liters/week, compared to a reduction of 2.85 liters/week in the placebo group (p=0.0039). When administered once weekly, glepaglutide treatment resulted in a reduction in weekly PS of 3.13 liters/week, however this did not achieve statistical significance. A total of 9 patients treated with glepaglutide were completely weaned off PS (achieving enteral autonomy), while no placebo-treated patients were able to discontinue PS. For patients treated with glepaglutide twice weekly, 14% of patients (n=5) achieved enteral autonomy. In total, 102 of 106 participating patients completed EASE-1, of which 96 continued into the ongoing two-year, long-term safety and efficacy extension trial, EASE-2. EASE-2 (NCT03905707) is a randomized, double-blind trial in which SBS patients continued their randomly assigned treatment from EASE-1 with glepaglutide 10 mg once- or twice-weekly. Patients who received placebo in EASE-1 were re-randomized to treatment with either glepaglutide 10 mg once- or twice-weekly. In an interim analysis conducted after at least six months of treatment, clinical response to glepaglutide across the key efficacy endpoints was generally maintained or showed continued improvement, including additional patients on both doses weaning off PS. Patients who complete EASE-2 are eligible to participate in EASE-3 (NCT04881825), evaluating glepaglutide administered once weekly using an autoinjector. An interim analysis of EASE-3, conducted with the first 57 patients rolled over from EASE 2, showed that the reduction in prescribed PS was generally maintained. EASE-4 (NCT04991311) was a Phase 3b trial to assess mechanistic effects of glepaglutide on intestinal fluid and energy uptake. The trial provides evidence of the pharmacodynamic effects of glepaglutide in improving intestinal absorption. In the second half of 2025, Zealand Pharma expects to initiate EASE-5, a single Phase 3 clinical trial that is anticipated to provide further confirmatory evidence for a regulatory submission in the U.S. About Zealand Pharma A/S Zealand Pharma A/S (Nasdaq: ZEAL) (“Zealand”) is a biotechnology company focused on the discovery and development of peptide-based medicines.
