Median progression free survival (PFS) close to double the reported median PFS in other clinical studies

(Oxford, UK and Conshohocken, US, 5 June 2017) Immunocore Limited, the world’s leading TCR company developing biological drugs to treat cancer, infectious diseases and autoimmune diseases today announces compelling single agent clinical data from the intra-patient dose escalation Phase I clinical trial of its lead programme, IMCgp100, which was presented in a poster session at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago on June 3 2017.

Immunocore’s intra-patient dose escalation Phase I IMCgp100 study recruited 19 metastatic uveal melanoma patients and demonstrated a median progression free survival (PFS) by RECIST v1.1 of 5.6 months, which compares favourably with reported median PFS ranging from 2.6-2.8 months. The 24 weeks (6 months) PFS rate is 57%, which again compares favourably with 19-27% previously reported in other clinical studies.
Based on the promising data presented here with IMCgp100 in patients with metastatic uveal melanoma, Immunocore is initiating a pivotal trial in the first-line setting to advance IMCgp100 towards commercialization.

Dr Christina Coughlin, Chief Medical Officer at Immunocore, commented: “We are excited to share these data in advanced uveal melanoma at ASCO. To our knowledge, no other drug treatments, including checkpoint inhibitors, have demonstrated such positive results in metastatic uveal melanoma before. We hope these data, combined with our orphan drug designation in the US, will help us to rapidly advance IMCgp100 through clinical development in order to make IMCgp100 available to patients as soon as possible.”

Dr Takami Sato, MD, PhD, Department of Medical Oncology, Kimmel Cancer Center, Thomas Jefferson University, commented: “This new data presented here at ASCO are compelling and we believe there is an opportunity to have an effective new treatment option for patients with metastatic uveal melanoma where the unmet need is very high.”
