‘Practice-changing’ results
“This is the first randomized controlled trial to be positive for overall survival in uveal melanoma. These are seminal and practice-changing results,” said AACR discussant Caroline Robert, MD, PhD, of Gustave Roussy and Paris-Saclay University in France.
She observed that the biology of uveal melanoma is distinct from that of cutaneous melanoma, and future research will have to address why tebentafusp doesn’t work as well in cutaneous melanoma. Tebentafusp will be evaluated in combination with immune checkpoint inhibitors as well, she added.
The major limitation of tebentafusp, Dr. Hassel observed, is that it can be used only in HLA-A*02:01-positive patients. “There still remains an unmet need for patients who do not have this particular surface protein,” she said.
The study was sponsored by Immunocore. Dr. Hassel disclosed relationships with Immunocore and other companies. Dr. Robert disclosed relationships with Bristol Myers Squibb, Pierre Fabre, Novartis, and other companies.
