Apexigen Announces Positive Interim Results from Phase 2 Trial Evaluating its CD40 Antibody, Sotigalimab, in Combination with Doxorubicin in Patients with Liposarcoma
SAN CARLOS, Calif., Nov. 14, 2022 (GLOBE NEWSWIRE) -- Apexigen, Inc. (NASDAQ: APGN) a clinical-stage company focused on developing innovative antibody-based therapeutics for the treatment of cancer with a focus on immuno-oncology, today announced topline data from an ongoing Phase 2 investigator sponsored trial in collaboration with Columbia University, evaluating sotigalimab, Apexigen’s agonist antibody targeting CD40, in combination with standard of care doxorubicin (dox), in patients with advanced soft tissue sarcoma (STS). In the subgroup of patients with liposarcoma (LPS), the second most common STS, treatment with sotigalimab combined with dox resulted in a median progression-free survival (mPFS) of 12.45 months relative to the historically observed mPFS of less than 5 months in patients treated with dox monotherapy.
- In contrast, results from the ongoing Phase 2 trial showed the subgroup of patients with LPS treated with sotigalimab in combination with dox achieved a mPFS more than double than historically seen with dox alone.
- This impressive increase in PFS is an improvement of clinical benefit that builds on the standard of care treatment of this disease.
- Further, these results could inform a potential Phase 3 registration-enabling study for patients with LPS in the first-line setting.
- Results support the initiation of an expansion cohort with an additional 10 patients to inform a potential phase 3 registration-enabling trial in first-line LPS patients.
