Successful completion of the first stage of the phase IIa clinical trial of naptumomab in combination with docetaxel and the study is now enrolling into the second stage

Lund, June 1, 2022 - Active Biotech (NASDAQ STOCKHOLM: ACTI) and its partner NeoTX announce today 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.

We are pleased by these early encouraging observations and are excited to follow the progress of the trial, which is now enrolling in its second stage, says Erik Vahtola, Chief Medical Officer at Active Biotech. Patients with advanced NSCLC who have progressed on CPI and standard chemotherapy currently have limited treatment options and new treatment alternatives are needed.
