Immunome Completes Acquisition of AL102, a Phase 3 Asset for the Treatment of Desmoid Tumors, From Ayala

Immunome, Inc. (Nasdaq: IMNM), a biotechnology company focused on developing first-in-class and best-in-class targeted cancer therapies, today announced the successful completion of its purchase of AL102 and related drug candidate AL101 from Ayala Pharmaceuticals, Inc.

“AL102 is a high-quality asset that complements our existing pipeline of targeted cancer therapies,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer of Immunome. “We believe that AL102 can establish a new standard of care for the treatment of desmoid tumors. In parallel, we are excited to advance our preclinical programs towards Phase 1 trials.”

AL102 is an investigational small molecule gamma secretase inhibitor currently being evaluated in the randomized Phase 3 RINGSIDE international trial for the treatment of desmoid tumors – a debilitating soft tissue malignancy. AL102 is a potential once-daily oral treatment for desmoid tumors. Data from clinical trials have shown AL102 may be more effective in treating desmoid tumors than OGSIVEO™ (nirogacestat), which recently became the first treatment approved for desmoid tumors by the U.S. Food and Drug Administration in November 2023.
