All patients are receiving the therapeutic combination of Immutep’s lead product candidate eftilagimod alpha (“efti” or “IMP321”) with KEYTRUDA® (or pembrolizumab, ananti-PD-1 therapy) at clinical trial sites across the U.S., Europe and Australia.
Immutep CSO and CMO, Dr Frederic Triebel said: “We are pleased with the recruitment of patients in theTACTI-002 clinical trial to date. After dosing the first patient in March this year, we already have 32 patients on study. In addition, we are encouraged by the early signals of efficacy seen in the more advanced part A of the study that appear to be consistent with the synergistic efficacy seen in combining efti with pembrolizumab in the TACTI-mel clinical trial. We very much look forward to presenting more detailed and more mature data at the 34th Annual Meeting of SITC in November.”
