Patient Recruitment for Melanoma Immunotherapy Trial

An innovative biotech company that specializes in developing DNA-based intratumoral immunotherapies needed help in recruiting patients unresponsive to anti-PD-1 therapy into a stage III/IV melanoma trial.

Phesi worked with the CEO and Chief Clinical and Regulatory Officer over a 4-week period to conduct a competitive analysis, reviewing enrollment rates in top recruiting centers across 39 recent, relevant trials:

Phesi recommended extending the current number of trial centres (7) by an additional 10 sites from either Germany or the US, and identified a list of 45 investigators. Phesi also assessed sites in Australia, the US and Canada (nominated by the client and partner CRO). Phesi forecasted the enrollment duration to be 19 months to recruit 63 patients.
