About the AIPAC trial
Active Immunotherapy PAClitaxel (AIPAC) is a Phase IIb clinical trial in HER2-negative/ HR positive metastatic breast cancer. Based on Immutep's LAG-3 technology, the study evaluates the combination of the Company's lead product candidate, eftilagimod alpha (efti, LAG-3Ig or IMP321), and a taxane chemotherapy, called paclitaxel. This combination is aimed at boosting the immune response against tumour cells compared to chemotherapy alone.

In the AIPAC trial, 227 hormone receptor positive metastatic breast cancer patients were randomised 1:1 to treatment A (paclitaxel chemotherapy plus placebo) or treatment B (paclitaxel chemotherapy plus efti) for six months. Patients received weekly paclitaxel at Days 1, 8 and 15 with either efti or placebo injected subcutaneously, on Days 2 and 16 of each 4-week cycle, repeated for 6 cycles. Thereafter, patients passed over to the maintenance phase with efti alone.
