Immutep Announced it Will Evaluate Efti in Triple Combination Therapy Phase I Study with Chemotherapy and an anti-PD-1 Therapy

Immutep Limited (NASDAQ:IMMP) announces it has signed an agreement to commence a new Phase I trial, called INSIGHT-003, to evaluate the combination of lead product candidate eftilagimod alpha ("efti" or "IMP321") in conjunction with an existing approved standard of care therapy consisting of a chemotherapy agent and ananti-PD-1therapy.

INSIGHT-003 will be an investigator-initiated trial conducted bythe Institute of Clinical Cancer Research IKF at Krankenhaus Nordwest in Frankfurt. The trial will be run as an amendment to the protocol of the ongoing INSIGHT trial as the third arm (Stratum C) with Prof. Dr. Salah-EddinAl-Batran as lead investigator.

Up to 20 patients with various solid tumours will be recruited to participate in the trial.Patients will receive 30 mg doses of efti every two weeks for 24 weeks in conjunction with standard of care chemotherapy plus anti-PD-1 therapy.Thereafter, patients will enter a maintenance phase and receive either efti alone or in double or continued triple combination withanti-PD-1therapy. The trial will assess the safety, tolerability and initial efficacy of the combination.

All regulatory and ethical approvals have been received, enabling recruitment to commence. The first patient is expected to be enrolled in Q3 of calendar year 2021, with first interim results expected in 2022.

Commenting on the new trial, Immutep CEO Marc Voigt said: "Testing efti as part of a triple combination therapy is an important and exciting expansion of our development program. Efti activates the immune system and could bring a significant benefit to multiple approved standard of care therapies and experimental therapies. Together with our other trials, we are building a very robust pool of data to understand how efti can ultimately improve outcomes for cancer patients."

Prof. Salah-EddinAl-Batran, Lead Investigator of the INSIGHT trial said: "There is a solid scientific rationale for adding efti to certain existingstandard-of-carechemotherapy plusanti-PD-1regimen in a triple combination approach and we are excited about the possibility of generating the first safety and efficacy data for theefti-add-ontriple combination in our INSIGHT trial platform."
