Clinical Trials contribute to the advancement of medicine

Our clinical trials are designed to be ethical, inclusive and scientifically robust, in line with UK regulations. Decisions about taking part in a clinical trial are always made by patients together with their healthcare professionals. By studying medicines in diverse populations, we aim to generate evidence that is relevant to real‑world clinical practice.

Every condition is untreatable until it isn’t.

For 150+ years, we’ve rewritten
significant chapters in medical history. We
continually work to overcome some of the
toughest healthcare challenges around
the world.

OUR HISTORY

Advancing science for health for
six generations

Founder Colonel Eli Lilly combined scientific rigour, passion for discovery, and caring for the community. From the first company to print ingredients on the label to the first company to make medicine accessible regardless of insurance status, Lilly continues to put people at the centre of the medicine we make.
