Text saying "trial me is built by women who've lived the problem & experts determined to fix it."

Our why

TrialMe was created out of lived experiences of being dismissed, overmedicated, and ultimately left without real options within the healthcare system.

The idea was shaped - and validated - at an AstraZeneca hackathon, where it won for addressing a critical gap in medical research

Women make up only up to 34% of Phase I trial participants and experience twice as many adverse drug reactions as men.

TrialMe was built to close this gap by making clinical trial participation accessible, understandable, and compatible with real life.
