About AIPAC (Active Immunotherapy PAClitaxel)
AIPAC is the acronym for Prima’s multicentre, Phase IIb, randomised, double-blind, placebo-controlled study in hormone receptor-positive metastatic breast carcinoma patients receiving IMP321 (LAG-3Ig fusion protein) or placebo as adjunctive to a standard chemotherapy treatment regimen of paclitaxel. The primary purpose of the AIPAC trial is to determine the clinical benefit of IMP321 in terms of Progression-Free Survival as the primary clinical endpoint in this patient population. The study consists of two parts: a safety run-in phase (15 patients) and a randomized and controlled phase (226 patients). Details of the AIPC study are posted on www.clinicaltrials.gov (clinicaltrials.gov identifier NCT 02614833).
