Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or “the Company”), a clinical-stage biotechnology company developing novel LAG-3 immunotherapies for cancer and autoimmune disease, today announces that positive feedback has been received from the US Food and Drug Administration (“FDA”) regarding the planned TACTI-004 Phase III trial of eftilagimod alfa (“efti”) in combination with KEYTRUDA® (pembrolizumab), MSD’s anti-PD-1 therapy, and histology-based platinum doublet chemotherapy for the treatment of first-line metastatic non-small cell lung cancer (1L NSCLC), regardless of PD-L1 expression.
The FDA feedback from this Type C meeting, along with feedback previously received from the Paul-Ehrlich-Institut (“PEI”) and the Spanish Agency for Medicines and Health Products (“AEMPS”), concludes the preparatory regulatory interactions for the design of this registrational trial. This marks a significant step forward to develop an effective treatment for non-squamous and squamous 1L NSCLC patients who have high, low, or no PD-L1 expression and are eligible for anti-PD-1 therapy.\
The TACTI-004 Phase III trial, which will enrol ~750 patients, is based on the positive efficacy and safety data in 1L NSCLC generated from the TACTI-002 Phase II and INSIGHT-003 trials.
“We are pleased with the FDA’s feedback as this allows us to successfully conclude our regulatory preparation for the TACTI-004 registrational trial. This represents a key milestone in our late-stage development process for efti centred on potentially driving a new standard of care globally in the treatment of non-small cell lung cancer. We hope to achieve this through efti in combination with KEYTRUDA, which has led to strong efficacy data with a favourable safety profile in 1L NSCLC patients regardless of PD-L1 expression,” stated Christian Mueller, Immutep’s SVP, Regulatory and Strategy.
