Key Announcement
Adagene Inc. (Nasdaq: ADAG), a company dedicated to innovative antibody-based therapies, has announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to its investigational therapy, muzastotug. This designation applies to muzastotug, in conjunction with Merck's anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), for treating adult patients with microsatellite stable metastatic colorectal cancer (MSS mCRC) who do not have active liver metastases.
Understanding Muzastotug
Muzastotug is a next-generation masked anti-CTLA-4 SAFEbody® designed to enhance safety and efficacy. This therapy aims to overcome regulatory T cell (Treg) resistance in tumors, presenting a therapeutic index that surpasses current CTLA-4 therapies. The Fast Track designation supports the urgency of development and underscores the potential efficacy of muzastotug based on emerging clinical data.
- Fast Track Designation: Facilitates expedited review for therapies addressing serious conditions with unmet medical needs.
- Emerging Clinical Evidence: Initial trials indicate encouraging efficacy, durability of responses, and a favorable safety profile.
Implications for Patients
Dr. Peter Luo, Chief Executive Officer and President of R&D at Adagene, stated, “Receiving Fast Track designation marks an important milestone for Adagene and further validates the promise of our SAFEbody® technology…” He expressed confidence that muzastotug could reshape treatment paradigms, potentially offering patients enhanced survival rates and improved quality of life.
Phase 2 and Future Trials
Adagene plans to launch a phased development approach for muzastotug, with a randomized Phase 2 trial expected to begin in 2027. Key trial design aspects confirmed by the FDA include:
- Patient Population: Late-line patients with MSS CRC without liver metastases, including peritoneal metastasis.
- Dosing Strategy: Patients will be randomized to receive either 10 mg/kg or 20 mg/kg of muzastotug alongside pembrolizumab.
- Phase 2 Trial Design: Enrollment of up to 30 patients per treatment arm.
- Endpoints: The primary endpoint for Phase 2 will be the overall response rate (ORR). Secondary endpoints will focus on duration of response (DOR), progression-free survival (PFS), and overall survival (OS).
