• Ikena to discontinue development of IK-930
  
• IK-595 dose escalation continues in RAS and RAF mutant cancers; Encouraging PK and PD profile shown to date
• Ended first quarter with $157.3 million; Exploring strategic options to maximize shareholder value

BOSTON, May 28, 2024 (GLOBE NEWSWIRE) -- Ikena Oncology, Inc. (Nasdaq: IKNA, “Ikena,” “Company”) today announced discontinuation of the clinical IK-930 program, the Company’s TEAD1- selective Hippo pathway inhibitor and continued clinical development of IK-595, a novel MEK-RAF molecular glue. Concurrently, Ikena is evaluating strategic options for both the Company and its development pipeline.

“Ikena is dedicated to thoughtfully putting our capital to work towards impactful treatments for patients, and in doing so building value for our shareholders. Together with our board of directors, we made the difficult decision to wind down the IK-930 program. Going forward, we believe that IK-930’s profile may enable combination opportunities with other targeted agents through partnerships,” commented Mark Manfredi, Ph.D., Chief Executive Officer of Ikena. “Our MEK-RAF molecular glue, IK-595, continues to progress rapidly in the clinic with encouraging early PK and PD data which supports a potentially differentiated therapeutic index. This is key to treating the broad population of patients suffering from RAS and RAF mutant cancers where other MEK inhibitors have failed.”
