BOSTON, Feb. 21, 2023 (GLOBE NEWSWIRE) -- Aileron Therapeutics (Nasdaq: ALRN) today announced that a review of initial data from its Phase 1b chemoprotection trial of ALRN-6924 in patients with p53-mutated breast cancer showed that patients in the trial experienced severe neutropenia (Grade 4) and alopecia. The primary endpoint of the Phase 1b open-label trial, which was evaluating ALRN-6924 in patients with breast cancer receiving neoadjuvant or adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide, or “TAC” chemotherapy, was duration and incidence of severe neutropenia in cycle 1. Incidence of chemotherapy-induced alopecia (hair loss) was a secondary endpoint. Based on these findings, Aileron has decided to terminate the Phase 1b breast cancer trial and further development of ALRN-6924.
