Immutep Completes Recruitment of Initial Cohort in 1st Line NSCLC Patients for TACTI-002 Trial

  • Recruitment for 2nd line (PD-1 refractory) NSCLC and 2nd line HNSCC cohorts of the TACTI-002 trial, conducted in collaboration with MSD, are ongoing
  • Initial data from the TACTI-002 study expected mid-2019

/EIN News/ -- SYDNEY, Australia, June 13, 2019 (GLOBE NEWSWIRE) -- Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep” or “the Company”), a biotechnology company developing novel immunotherapy treatments for cancer and autoimmune diseases, announces that 17 patients have been enrolled into the first cohort of the first line non-small cell lung cancer (NSCLC) arm (Part A) of the Phase II TACTI-002 clinical trial. This completes patient recruitment of the initial cohort of the study Part A.  TACTI-002 is being conducted in collaboration with Merck & Co., Inc., Kenilworth, NJ, USA (known as “MSD” outside the United States and Canada).

Patient enrollment for TACTI-002 commenced in early 2019, with the first patient being dosed in March 2019.

Under the Simon’s two-stage design, the initial cohort of first line NSCLC patients may be enlarged by a further 19 patients, if a pre-defined number of responses are observed.  Ten study centers are now recruiting patients into the trial across the U.S., Europe and Australia, with three additional sites expected to commence recruitment in the coming months.

Dr. Frederic Triebel, Immutep CSO and CMO, commented, “Efti has a unique mode of action. As an antigen presenting cell activator, it is successful in activating dendritic cells that process and present antigens for recognition by the T cell receptor on T lymphocytes. Efti is the only antigen presenting cell activator targeting MHC class II molecules currently in clinical development, setting it apart from other immuno-oncology therapies in the landscape.

"It is very encouraging that we are achieving such positive traction with recruitment for our TACTI-002 study of efti, which commenced dosing patients just over three months ago. We expect to report the first data from this trial in mid-2019.”

Recruitment is ongoing for the initial cohorts of the 2nd line NSCLC and 2nd line HNSCC of the Phase II TACTI-002 clinical trial. These cohorts may also be enlarged if a pre-defined number of responses are observed.
