Ikena Oncology Reports Third Quarter 2022 Financial Results and Provides a Corporate Update

Initial clinical data of AHR antagonist, IK-175, shows treatment is well-tolerated and demonstrates anti-tumor activity both as a monotherapy and in combination with nivolumab

Progressing lead targeted oncology program in TEAD inhibition with IK-930; advanced through multiple dose escalation cohorts

Recent preclinical data presented potential of IK-930 in preventing therapeutic resistance to other targeted therapies; first combination cohort with osimertinib announced through collaboration with AstraZeneca

Next development candidate in RAS pathway to be announced by year end 2022

BOSTON, Nov. 07, 2022 (GLOBE NEWSWIRE) -- Ikena Oncology, Inc. (Nasdaq: IKNA, “Ikena”), a targeted oncology company forging new territory in patient-directed cancer treatment, today announced financial results for the third quarter ended September 30, 2022. The Company also shared updates across its pipeline, including highlighting the data from the Society for Immunotherapy of Cancer Conference (SITC) abstract released this morning from the IK-175 clinical program in urothelial carcinoma.

“I am thrilled we are able to share an update on IK-175 later this week at SITC, and that we are seeing a benefit for some patients in such a heavily pre-treated population. We believe IK-175 has the potential to expand the number of cancer patients who can benefit from immune therapy and are looking forward to continuing our efforts with our collaborator, Bristol Myers Squibb,” commented Mark Manfredi, PhD, Chief Executive Officer at Ikena. “It has been an extremely productive time for us in our targeted oncology efforts as well, with our RAS pathway development candidate coming shortly, and advancing our TEAD program. IK-930’s progress in the clinic, and the data demonstrating IK-930’s potential in preventing and reversing resistance to targeted agents, bring us several key steps closer towards our goal of getting this unique and novel therapy to patients.”

Society for Immunotherapy of Cancer conference abstracts released this morning; IK-175 AHR inhibition program partnered with Bristol Myers Squibb (BMS)

Third Quarter 2022 Financial Results

As of September 30, 2022, Ikena had $174.4 million in cash, cash equivalents, and marketable securities, and believes this will be sufficient to meet its operating requirements through mid-2024. Net cash used in operating activities was $17.2 million for the three months ended September 30, 2022, as compared to $18.0 million of cash used in operating activities for the same period in 2021.

Research and development revenue under collaboration agreement of $6.4 million and $3.7 million for the three months ended September 30, 2022 and 2021, respectively, is related to the BMS Collaboration Agreement for the IK-175 and IK-412 programs which was executed in January 2019. The increase in revenue during the three months ended September 30, 2022, as compared to the same period in the prior year, was primarily due to an increase in manufacturing activities as a result of the substantial completion of manufacturing efforts related to the IK-412 program.

Research and development expenses were $18.9 million and $13.4 million for the three months ended September 30, 2022 and 2021, respectively. The increase was primarily related to personnel and overhead costs due to an increase in headcount, expenses incurred for discovery stage programs, and an increase in manufacturing activities as a result of the substantial completion of manufacturing efforts related to the IK-412 program.

General and administrative expenses were $5.4 million and $4.9 million for the three months ended September 30, 2022 and 2021, respectively. The increase was primarily attributable to an increase in compensation expense due to an increase in headcount and in insurance expense, as well as general increases in legal expenses to support our operations as a public company.

About Ikena Oncology
Ikena Oncology™ is focused on developing novel therapies targeting key signaling pathways that drive the formation and spread of cancer. The Company’s lead targeted oncology program, IK-930, is a paralog-selective TEAD inhibitor addressing the Hippo signaling pathway, a known tumor suppressor pathway that also drives resistance to multiple targeted therapies. The Company’s ongoing discovery research spans other targets in the Hippo pathway as well as the RAS signaling pathway. Additional programs targeting the tumor microenvironment and immune signaling are in the clinic, including IK-175, an AHR antagonist, which is being developed in collaboration with Bristol Myers Squibb. Ikena’s pipeline is built on addressing genetically defined or biomarker-driven cancers and developing therapies that can serve specific patient populations in need of new therapeutic options.
