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

Advancement across Company’s pipeline towards regulatory and data milestones

BOSTON, Aug. 11, 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 second quarter ended June 30, 2022. The Company also shared updates across its pipeline, including its clinical stage programs, with the continued advancement of IK-930, an oral transcriptional enhanced associate domain (TEAD) inhibitor product candidate targeting the Hippo signaling pathway, and IK-175, an oral aryl hydrocarbon receptor (AHR) antagonist.

“We are excited about the progress Ikena has made in the first half of 2022, especially on our IK-930 and IK-175 programs. The entire team and I are looking forward to continuing the momentum in both trials and sharing initial clinical data from both programs in the coming months and next year,” said Mark Manfredi, Ph.D., Chief Executive Officer of Ikena. “These programs exemplify the foundation on which we have built and continue to build our pipeline — therapies that have the potential to benefit patient populations with significant unmet medical needs. As always, I am grateful to our team for their excellent work across our programs so that we can continue working towards a world where every cancer patient has a cure.”

Summary of Recent Pipeline Progress and Corporate Update

• IK-930: TEAD Inhibitor in the Hippo Signaling Pathway
  • In May 2022, the FDA granted Fast Track designation for IK-930 in the treatment of NF2-deficient mesothelioma, following the Orphan Drug designation granted for mesothelioma earlier in the year
  • Continued recruitment in the dose escalation phase of the first-in-human Phase 1 study of IK-930 (NCT05228015) designed to evaluate safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity
• IK-175: AHR Inhibition Program Partnered with Bristol Myers Squibb (BMS)
  • The Phase 1a/1b trial of IK-175 (NCT04200963) in metastatic urothelial carcinoma continues to recruit patients who have progressed on prior lines of therapy, including checkpoint inhibitors, in the second stage of both the monotherapy and combination expansion cohorts
  • Ikena plans to present initial clinical data from this trial in the second half of 2022
  • The FDA cleared the IND for the Phase 1b trial of IK-175 in head & neck cancer (NCT05472506) and Ikena is expected to dose a first patient before the end of the year

• Research and Corporate Development
  • The Ikena early pipeline continues to progress and mature towards our next development candidates in the Hippo and RAS pathways

Second Quarter 2022 Financial Results

Ikena had $192.8 million in cash, cash equivalents, marketable securities as of June 30, 2022, as compared to $232.2 million as of December 31, 2021. Ikena believes its available cash, cash equivalents, and marketable securities will be sufficient to meet its operating requirements through mid-2024. Net cash used in operating activities was $19.5 million for the three months ended June 30, 2022, as compared to $15.7 million of cash used in operating activities for the same period in 2021.

Research and development revenue under collaboration agreement of $0.4 million and $3.5 million for the three months ended June 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 decrease in revenue during the three months ended June 30, 2022, as compared to the same period in the prior year, was primarily due to a change in estimate of the development services expected to be performed during the term of the collaboration agreement related to IK-175 and the strategic decision made in December 2021 to pause the development of IK-412, outside of the committed manufacturing efforts, for the remainder of the BMS contract term.

Research and development expenses were $15.5 million for the three months ended June 30, 2022, compared to $11.4 million for three months ended June 30, 2021. The increase was primarily related to personnel and overhead costs due to an increase in headcount and expenses incurred for discovery stage programs.

General and administrative expenses were $5.8 million for the three months ended June 30, 2022, as compared to $4.9 million for the three months ended June 30, 2021. 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.
