[{"type":"text","content":"--Interim report completed by ALX for a standard ongoing non-clinical safety study --Based on the safety study results, the FDA has lifted a previously set partial clinical hold and cap on patient enrollment in ASPEN-03 and ASPEN-04 --The first of two distinct randomized Phase 2 head and neck cancer studies in collaboration with Merck has been initiated; enrollment in ASPEN-03 is ongoing BURLINGAME, Calif., June 14, 2021 (GLOBE NEWSWIRE) -- ALX Oncology Holdings Inc., (“ALX Oncology”) (Nasdaq: ALXO), a clinical-stage immuno-oncology company developing therapies that block the CD47 checkpoint pathway, today announced updates on its ALX148 Phase 2 studies in patients with advanced head and neck squamous cell carcinoma (“HNSCC”). The U.S. Food and Drug Administration (“FDA”) informed ALX Oncology that it reviewed its standard non-clinical safety study and has lifted the previously set partial clinical hold and cap on patient enrollment. The two randomized Phase 2 studies, ASPEN-03 and ASPEN-04, are potentially registrational with patient enrollment unimpacted in either study. ASPEN-03 has initiated with enrollment ongoing.

Both studies are being conducted in collaboration with Merck. The first study, ASPEN-03, is evaluating the efficacy of ALX148 in combination with pembrolizumab for the first-line (“1L”) treatment of patients with PD-L1 expressing metastatic or unresectable, recurrent HNSCC with a Combined Positive Score (“CPS”) ≥ 1. The second study, ASPEN-04, is evaluating ALX148 in combination with pembrolizumab and standard chemotherapy for the 1L treatment of patients with metastatic or unresectable, recurrent HNSCC (any CPS value).
