Evorpacept · 6 trials · 12 indications
Evaluate the ORR of evorpacept in combination with trastuzumab and single-agent chemotherapy in the sub-population of participants with metastatic HER2-positive breast cancer who express CD47 (CD47+). ORR is defined as a best overall response (BOR) of confirmed complete response (CR) or partial response (PR) using RECIST v1.1 based on BICR assessment.

Evorpacept is an investigational oncology drug being studied for metastatic cancer, breast cancer, gastric cancer, bladder cancer, and head and neck cancer. It is in clinical development for advanced solid tumors and lymphomas, and is being evaluated in combination with other therapies for specific cancer types.
Evorpacept targets CD47, a protein that cancer cells use to evade the immune system. It is a CD47 inhibitor, designed to block the "don't eat me" signal that CD47 sends to macrophages, potentially enabling the immune system to attack and destroy cancer cells.
Evorpacept is being developed by ALX Oncology Holdings Inc., a biopharmaceutical company traded on NASDAQ under the ticker symbol ALXO. The company is conducting clinical trials to evaluate the drug's safety and efficacy in various cancer indications.
Evorpacept is in Phase 1 and Phase 2 clinical trials. It is an investigational drug, not yet approved by the FDA. Ongoing trials include a Phase 2 study in head and neck cancer and a Phase 2 study in HER2+ gastric cancer, with earlier-stage trials completed.
Evorpacept is being studied in several clinical trials, including NCT03013218 (completed, advanced solid tumors and lymphoma), NCT04675333 (active, head and neck cancer), NCT05002127 (active, gastric cancer), and NCT05524545 (completed, bladder cancer). These trials are part of the ASPEN program.
Yes, Evorpacept is also known as ALX148. Both names refer to the same investigational drug being developed by ALX Oncology. Clinical trial registrations and scientific publications may use either name to describe the compound.
