Active Biotech and its partner NeoTX announce the successful completion of the first stage of a Simon 2 stage phase IIa clinical trial of naptumomab estafenatox (NAP, naptumomab), in combination with docetaxel in patients with advanced or metastatic non-small cell lung cancer (NSCLC) who have been previously treated with chemotherapy and checkpoint inhibitors (CPIs). In the study, the patients are treated with NAP for 4 consecutive days and with docetaxel at a standard dose on day 5 in 21-day treatment cycles. The first stage of this trial required a minimum of two responses out of ten patients to move to the second stage of the trial, which is now enrolling.
