Positive Interim Data of Dose Escalation Phase of ALG.APV-527 Ph 1 Study in Solid Tumor Cancers Expressing Tumor Antigen 5T4 announced

“I am pleased to share that we are now dosing cohort four, heading into higher dose ranges where we believe there is potential for increased signs of clinical activity based on preclinical models. We have treated patients with multiple tumor types including breast, pancreatic, non-small cell lung cancer and colorectal cancer. It is our belief that continued analysis of this cross section of tumor types will offer important insights about ALG.APV-527 that can be used to increase our success in later stage development,” said Dirk Huebner, MD, Chief Medical Officer at Aptevo. “Additionally, as the trial has progressed, we have seen growing enthusiasm among our clinical sites, evidenced by a long and growing waiting list of patients who would like to participate in the study. We look forward to announcing additional data later in the year.”
