Immutep Announces Publication of TACTI-002 Abstract at ESMO’s European Lung Cancer Congress 2022

  • New interim data from TACTI-002 (Part B) evaluating the combination of efti and pembrolizumab in 2nd line, confirmed PD-1/PD-L1 refractory, non-small cell lung cancer (NSCLC) patients
  • Combination continues to be safe and well tolerated, and shows encouraging signs of antitumour activity in this difficult to treat patient population with limited treatment options
  • Overall Response Rate (ORR) of 6% (2/36) and Disease Control Rate (DCR) of 36% (13/36) in the intent to treat population; both partial responses are confirmed and durable
  • Important additional data on safety and efficacy including 6 months Overall Survival (OS), Tumour Growth Kinetics, and details of the confirmed partial responses will be presented in the poster at ELCC

About the TACTI-002 Trial
TACTI-002 (Two ACTive Immunotherapies) is being conducted in collaboration with Merck & Co., Inc., Kenilworth, NJ, USA (known as “MSD” outside the United States and Canada). The study is evaluating the combination of eftilagimod alpha (efti) with MSD’s KEYTRUDA® (pembrolizumab) in patients with second line head and neck squamous cell carcinoma or non-small cell lung cancer in first and second line.

The trial is a Phase II, Simon’s two-stage, non-comparative, open-label, single-arm, multicentre clinical study that is taking place in study centres across Australia, Europe, and the US.

Patients participate in one of the following:

  •  Part A - first line Non-Small Cell Lung Cancer (NSCLC), PD-X naïve - given the promising results of the first two stages of Part A, an expansion stage with additional patients was commenced in November 2020 to assist with trial design in subsequent late-stage settings
  • Part B - second line NSCLC, PD-X refractory
  • Part C - second line Head and Neck Squamous Cell Carcinoma (HNSCC), PD-X naïve

TACTI-002 is an all-comer study in terms of PD-L1 status, a well-known predictive marker for response to pembrolizumab monotherapy especially in NSCLC and HNSCC.

More information about the trial can be found on Immutep’s website or on ClinicalTrials.gov (Identifier:
NCT03625323).
