SYDNEY, Australia, May 17, 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, today announces more mature data relating to Part B of its ongoing phase I TACTI-mel clinical study of the Company’s lead product candidate, eftilagimod alpha (“efti” or “IMP321”) in patients with melanoma. The data was presented at the World Advanced Therapies & Regenerative Medicine Congress & Expo 2019 in London on May 17, 2019 by Dr Frédéric Triebel, Chief Scientific Officer and Chief Medical Officer of Immutep.
The ongoing TACTI-mel trial evaluates the combination of efti with anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in 24 patients with unresectable or metastatic melanoma. It is a multi-center, open label clinical trial that involves four cohorts of six patients, each cohort testing different dosages of efti, including 1 milligram (mg), 6 mg and 30 mg, in combination with pembrolizumab. Part B of the study includes a cohort of 6 patients at 30 mg of efti in combination with pembrolizumab, starting at cycle 1, day 1 and with a treatment duration of 12 months.
Consistent with previous data reported at 6 months of combination treatment (March 2019), patients in Part B continue to report positive results in terms of tumour reductions after 9 months of treatment. Four patients are continuing to receive treatment. No new safety data or data from Part A of the study have been reported. The key findings from Part B are:
|Part B (starting cycle 1, day 1 of pembro therapy)
|Overall Response Rate (ORR)||50%|
|Disease Control Rate (DCR)||66%|
