BOSTON, Aug. 10, 2023 (GLOBE NEWSWIRE) — Ikena Oncology, Inc. (Nasdaq: IKNA, “Ikena,” “Company”), a targeted oncology company forging new territory in patient-directed cancer treatment, today announced financial results for the quarter ended June 30, 2023. The Company also provided pipeline and corporate updates from the quarter and recent months.

“It has been a busy time at Ikena, with new high-quality investors and peers sharing our confidence in our targeted oncology pipeline translating to important corporate milestones. We are in a strong financial position and remain on track to deliver on our development milestones for both IK-930 and IK-595 this year, and to fund additional and potentially broader data events as we go deeper into the programs,” said Mark Manfredi, PhD, Chief Executive Officer of Ikena. “The important progress we made in the second quarter has continued to set the programs and company up for success, especially the presentation of our differentiated, selective design of IK-930 and the clinical target validation of the Hippo pathway. We are looking forward to sharing more later this year, including the initial clinical data from IK-930, and updates on the IND submission and clinical plan for IK-595, all of which we see as further solidifying Ikena as a leader in the targeted oncology space and driving value for patients and shareholders.”

Summary of Recent Pipeline Progress and Corporate Update

IK-930: TEAD1-Selective Hippo Pathway Inhibitor

• IK-930’s differentiation was showcased at the American Association for Cancer Research (AACR) Annual Meeting in April 2023
  • The therapeutic index advantages of IK-930’s TEAD1 selectivity was highlighted, including preclinical datasets comparing IK-930 to panTEAD inhibition,
  • The combination of IK-930 with targeted agents (EGFR, KRAS G12C, MEK inhibitors) reduced drug-resistant persister cells, potentially broadening the benefits of targeted therapies
• The ongoing Phase 1 study is progressing as planned and has advanced through multiple dose escalation cohorts, which will be included in the initial clinical data update planned for the fourth quarter of 2023

IK-595: MEK-RAF Complex Inhibitor

• IND application submission for IK-595 planned by year end 2023
• Additional preclinical updates and indication selection data for IK-595 will be presented in 2023 at the 5^th Annual RAS-Targeted Drug Discovery Development Conference in September and AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in October

IK-175: AHR Inhibitor in Collaboration with Bristol Myers Squibb

• The Phase 1 clinical trial in urothelial carcinoma has completed enrollment and the program is eligible for opt-in from Bristol Myers Squibb through early 2024

Corporate Update

• Completion of underwritten registered offering in May 2023 for gross proceeds of approximately $40 million
• Acquisition of Pionyr Immunotherapeutics Inc. in August 2023 resulted in approximately $43 million in net cash added to the Ikena balance sheet
• Together with its existing cash, cash equivalents, and investments, the Company believes that cash at hand will be sufficient to meet its operating requirements into 2026 and will fund additional data events for both IK-930 and IK-595 beyond the initial read outs

Financial Results for the Quarter Ended June 30, 2023

As of June 30, 2023, Ikena had $157.3 million in cash, cash equivalents and marketable securities, which does not include proceeds from the recent acquisition of Pionyr Immunotherapeutics Inc., which resulted in approximately $43 million in net cash added to the balance sheet subsequent to the quarter end June 30, 2023. Net cash used in operating activities was $18.1 million for the three months ended June 30, 2023, as compared to $19.5 million of cash used in operating activities for the same period in 2022.

Collaboration revenue was $2.0 million and $0.4 million for the three months ended June 30, 2023 and 2022, respectively. The increase in revenue was primarily due to a change in estimate made during the period ended June 30, 2022 of the development services expected to be performed during the term of the Bristol-Myers Squibb Collaboration Agreement related to IK-175.

Research and development expenses were $15.2 million and $15.5 million for the three months ended June 30, 2023 and 2022, respectively. The decrease in research and development expenses of $0.3 million was primarily due to decreases in clinical trial costs related to IK-175 and decreases in other discovery stage programs as a result of the Company prioritizing its focus on advancing its clinical stage programs, partially offset by an increase in IK-930 clinical trial costs and consulting fees.

General and administrative expenses were $5.3 million and $5.8 million for the three months ended June 30, 2023 and 2022, respectively. The decrease in general and administrative expenses was primarily attributable to a decrease in legal, consulting, and insurance expenses.
