Immutep, a leading Australian biotechnology company, announced that it has entered into a clinical trial collaboration and supply agreement with MSD (Merck) to evaluate the combination of Immutep’s lead immunotherapy product candidate eftilagimod alpha (“efti” or “IMP321”) with MSD’s anti-PD-1 therapy KEYTRUDA (pembrolizumab) in a new clinical trial that will evaluate the combination in several different solid tumours.
The planned Phase II clinical trial, referred to as TACTI-002 (Two ACTive Immunotherapies), will evaluate the safety and efficacy of this novel immunotherapy combination in patients with non-small cell lung cancer (“NSCLC”), head and neck cancer, or ovarian cancer. The TACTI-002 clinical trial will be a Phase II, Simon two-stage, non-comparative, open-label, single-arm, multicentre clinical study. Up to 120 patients across the three indications are planned to be treated in medical centres in Europe and the United States with the trial expected to commence in the second half of 2018.
The trial combines two immuno-oncology treatments with complementary mechanisms of action, analogous to releasing the brakes and pushing the accelerator of the body’s immune system at two different positions in the cancer immunity cycle. Immutep’s efti is a first-in-class antigen presenting cell (“APC”) activator which stimulates cancer-fighting T cells, while KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells.
