The company discontinued CLN-619 and CLN-617 and said partner Taiho will begin a rolling NDA for zipalertinib by year‑end, with pivotal enrollment completing in 1H 2026.

Cullinan Therapeutics (Nasdaq: CGEM) reported Phase 1 CLN-049 data in relapsed/refractory AML and MDS showing anti-leukemic activity and a manageable safety profile as of a June 2025 cutoff.

Key data: across target doses ≥6 μg/kg (n=23 AML) CRc 30% and ORR 57%; at 12 μg/kg (n=13) CRc 31% and ORR 69%. Responses occurred regardless of FLT3 mutational status, including 4 responses in 5 TP53‑mutated AML patients.

Preclinical results showed rapid, dose-dependent B cell depletion in human PBMCs from RA, Sjögren's, and SLE patients and in nonhuman primates after subcutaneous dosing, with sustained depletion in blood, bone marrow, and lymph nodes. In an SLE mouse model, CLN-978 reduced circulating B cells, anti-dsDNA IgG, and kidney IgG deposition. The company is advancing OUTRACE clinical programs in RA (NCT06994143), SjD (NCT07041099), and SLE (NCT06613360).
