Leadership Team
Step Pharma is led by a highly motivated management team and an exceptional syndicate of international investors, all driven to bring about a step change in cancer treatment for patients.
We are a group of like-minded, experienced executives, biotechnology entrepreneurs and drug developers who have come together to bring dencatistat to the clinic as fast as possible, drawing on our prior experience of developing and commercialising life-saving treatments.
Our vision is to redefine how cancer is treated and bring our targeted therapy to patients as soon as possible.
Step Pharma’s management team has more than 50 years of collective experience in successfully developing and commercialising breakthrough cancer treatments. We bring together a range of drug discovery and development, regulatory, clinical and operational expertise in biotech and pharma.
Founding Scientist
Prof. Alain Fischer
Alain Fischer is an internationally recognized expert in the genetics of immunological disorders, primarily immunodeficiency diseases, and the development of the lymphoid system.
In 2000 he was the first to obtain clinical success with gene therapy for the treatment of children affected by SCID disease (“bubble babies”) for which he was awarded the Louis Jeantet Prize for Medicine (2001), the INSERM “Grand Prix” (2008) and the Japan Prize in 2015. He is the author of more than 600 publications and until 2016 was the Head of the Imagine Institute where he still contributes actively to fundamental and clinical research.
