近日,麦科医药(2335.HK)核心产品MT1013的III期临床研究所有入组试验参与者(435名)均已完成研究治疗及试验方案规定的全部随访程序,正式出组。研究由此从“数据产生”阶段全面转入数据清理、数据库锁定、揭盲与统计分析阶段,计划2027年初完成全部研究工作,为后续NDA(上市许可申请)申报奠定数据基础。
一款“双靶点”创新药: 瞄准CKD-SHPT临床空白的“标本兼治”
MT1013是一种双靶点多肽创新药,可同时激活钙敏感受体(CaSR)并模拟成骨生长肽(OGP)机制。其作用聚焦于慢性肾脏病继发性甲状旁腺功能亢进症(CKD-SHPT)的两个关键致病环节:一方面作用于甲状旁腺的CaSR受体,降低甲状旁腺激素(PTH)水平;另一方面作用于疾病相关的成骨生长肽(OGP),促进骨骼生成。两种作用协同,有望实现矿物质与骨代谢的综合改善。
不同于传统单靶点拟钙剂仅调控 iPTH、缺乏直接促成骨作用,MT1013同时拥有拟钙剂活性与OGP 介导的骨合成效应。该在研新药当前开发定位为 CKD-SHPT治疗,后续计划拓展至CKD-MBD伴骨质疏松、非透析CKD-SHPT等适应症。
CKD-SHPT:透析患者常见且致命的并发症
CKD-SHPT 是慢性肾脏病患者(尤其是接受透析的终末期肾病患者)常见且严重的并发症,为 CKD 矿物质和骨异常(CKD-MBD)的核心表现之一。CKD-SHPT 可诱发肾性骨病、血管及软组织钙化等病变,临床可出现骨痛、骨脆性升高、病理性骨折、血管硬化与心血管负荷上升,显著升高患者心血管不良事件与死亡风险。
据弗若斯特沙利文资料,中国CKD-SHPT患病人数由2020年的1300万人增至2025年的1400万人,预计到2030年将达到1500万人,到2035年将达到1590万人。
研究设计与安全性监测
MT1013的III期临床试验为一项多中心、随机、双盲双模拟研究,旨在接受维持性血液透析的CKD-SHPT患者中比较MT1013与目前临床常用拟钙剂西那卡塞的疗效及安全性。主要终点为于疗效评估期间(EAP)各组血清iPTH水平较基线分别下降超过50%及超过30%的患者比例。该研究总共入组435名患者。
截至目前,根据III期临床研究现有安全性监测数据,尚未发现新的重大安全性风险信号。试验参与者整体脱落情况与试验设计阶段的预期基本一致。试验目前尚未揭盲,相关数据仍有待完成核查及最终统计分析。
向产品上市更进一步
本次里程碑的达成,标志着MT1013 向 NDA 申报与商业化落地迈出了关键一步,也为公司后续产品管线的推进积累了重要的注册临床经验。
麦科奥特将秉持以临床价值为导向的研发理念,稳步推进 MT1013 的注册申报工作,力争早日为 CKD-SHPT 患者提供新的治疗选择。

MT1013为麦科医药自主研发的全球首创(First-in-Class)CaSR/OGP双靶点多肽创新药,首发适应症为慢性肾脏病继发性甲状旁腺功能亢进症(CKD-SHPT)。其创新性融合钙敏感受体(CaSR)激动与成骨生长肽(OGP)模拟双重作用机制,在抑制甲状旁腺激素(PTH)分泌、调节钙磷代谢的同时,主动促进骨形成,有望实现从矿物质代谢控制到骨骼健康改善的综合管理。
Ⅱ期临床研究中,MT1013与已上市拟钙剂依特卡肽开展头对头比较,在iPTH、血钙及血磷三项综合达标率方面展现出明确优势,并在降低血管钙化关键风险指标物方面显示出积极信号,相关研究成果入选2025年美国肾脏病学会(ASN)肾脏周Late-Breaking Research。

All 435 participants enrolled in the Phase III trial of Micot Pharma(2335.HK)'s core product MT1013 have now completed study treatment and all protocol-specified follow-up procedures, formally concluding their participation. The study has fully transitioned from data generation to data cleaning, database lock, unblinding, and statistical analysis, with all study activities planned for completion in early 2027 to support the subsequent New Drug Application (NDA) submission.
A Dual-Target Innovative Drug Addressing Unmet Needs in CKD-SHPT Through a Two-Pronged Approach
MT1013 is a dual-target peptide that activates the calcium-sensing receptor (CaSR) and mimics osteogenic growth peptide (OGP) activity. It targets two key pathogenic processes in CKD-associated secondary hyperparathyroidism (CKD-SHPT): activating parathyroid CaSR to reduce parathyroid hormone (PTH) levels, while mimicking OGP activity to promote bone formation. Together, these mechanisms may improve mineral and bone metabolism.
Unlike conventional single-target calcimimetics, which regulate intact PTH (iPTH) without directly promoting bone formation, MT1013 combines calcimimetic activity with OGP-mediated anabolic effects on bone. The investigational drug is currently being developed for CKD-SHPT, with planned expansion into indications including CKD-mineral and bone disorder (CKD-MBD) with osteoporosis and non-dialysis CKD-SHPT.
CKD-SHPT: A Common, Potentially Fatal Complication in Dialysis Patients
CKD-SHPT is a common, serious complication of chronic kidney disease (CKD), particularly in dialysis patients with end-stage kidney disease, and a major manifestation of CKD-MBD. It can cause renal osteodystrophy and vascular and soft tissue calcification, with manifestations including bone pain, increased bone fragility, pathological fractures, vascular stiffness, and greater cardiovascular burden, significantly increasing the risks of adverse cardiovascular events and mortality.
According to Frost & Sullivan, China's CKD-SHPT population grew from 13 million in 2020 to 14 million in 2025 and is projected to reach 15 million by 2030 and 15.9 million by 2035.
Study Design and Safety Monitoring
The Phase III trial of MT1013 is a multicenter, randomized, double-blind, double-dummy study comparing its efficacy and safety with cinacalcet, a commonly used calcimimetic, in CKD-SHPT patients on maintenance hemodialysis. The primary endpoints are the respective proportions of patients in each group achieving serum iPTH reductions of >50% and >30% from baseline during the Efficacy Assessment Period (EAP). The study enrolled 435 patients.
To date, available Phase III safety monitoring data have identified no new significant safety risk signals. Overall participant dropout has been broadly consistent with study design expectations. The trial remains blinded, with data verification and final statistical analysis pending.
A Step Closer to Market Approval
This milestone marks a key step toward MT1013's NDA submission and commercialization, while providing valuable regulatory clinical trial experience for advancing the Company's pipeline.
Micot Pharma will maintain its clinical value-driven R&D approach, steadily advance MT1013's regulatory submission, and strive to offer CKD-SHPT patients a new treatment option as soon as possible.
About MT1013:
MT1013 is Micot Pharma's independently developed, global first-in-class CaSR/OGP dual-target innovative peptide drug, with CKD-associated secondary hyperparathyroidism (CKD-SHPT) as its lead indication. It combines CaSR agonism and OGP mimetic activity to suppress PTH secretion, regulate calcium and phosphorus metabolism, and actively promote bone formation, potentially enabling comprehensive management from mineral metabolism control to improved bone health.
In a Phase II head-to-head trial against the approved calcimimetic etelcalcetide, MT1013 demonstrated a clear advantage in the composite target achievement rate for iPTH, serum calcium, and serum phosphorus, alongside encouraging clinical signals for reducing vascular calcification key risk biomarker. The findings were selected for Late-Breaking Research at the American Society of Nephrology (ASN) Kidney Week 2025.
MT1013's confirmatory Phase III trial in China has completed the last participant's final study visit, with NDA submission expected in early 2027. In February 2026, Micot Pharma entered an exclusive commercialization partnership with Everest Medicines covering Greater China and Asia-Pacific excluding Japan, receiving an upfront payment of RMB 200 million, with a total potential deal value of up to RMB 1.24 billion.
