“We look forward ⁠to the presentation of clinical proof-of-concept data ‌later in 2026, ‌rapidly advancing AJ1-11095 into registrational clinical trials, and using our expertise in blood ⁠cancer to hopefully deliver another ⁠important new medicine to patients ⁠and hematologists,” said Jacob Van Naarden, president of Lilly Oncology.
