• Ikena receives approximately $43 million in net cash at closing
• New capital will further accelerate and expand development of Ikena’s targeted oncology pipeline

BOSTON and SOUTH SAN FRANCISCO, Calif., Aug. 07, 2023 (GLOBE NEWSWIRE) -- Ikena Oncology, Inc. (Nasdaq: IKNA, “Ikena”), a targeted oncology company forging new territory in patient-directed cancer treatment, and Pionyr Immunotherapeutics, Inc. (Pionyr), a privately-held, clinical-stage biotechnology company, today announced the closing of Ikena’s acquisition of Pionyr in an all-stock transaction. Ikena acquired all of Pionyr’s assets, including approximately $43 million in net cash, in exchange for shares of IKNA stock, in a combination of common stock and non-voting convertible preferred stock priced at $7.15 per share.

“Ikena has made incredible strides this year, and we are glad to welcome the Pionyr shareholders to the Ikena team as we head into a pivotal time for our targeted oncology programs,” said Mark Manfredi, Ph.D., Chief Executive Officer of Ikena. “The capital from this acquisition allows us to accelerate and expand our clinical efforts in IK-930 and further support our comprehensive clinical plan for IK-595 as we continue to build value through both depth and breadth in our pipeline. We are looking forward to sharing more updates from across our business and pipeline, including initial clinical data from IK-930 later this year.”

The transaction further strengthens Ikena’s financial position as the Company advances development of its targeted oncology programs. The new capital will enable Ikena to expand and accelerate its targeted oncology programs, including both IK-930, Ikena’s clinical program targeting the Hippo pathway with initial clinical data expected this year, and IK-595, a MEK-RAF complexing inhibitor expected to have an IND submitted this year. The new Ikena shareholders include New Enterprise Associates, SV Health Investors, Sofinnova Investments, Vida Ventures, and Gilead Sciences. Gilead Sciences acquired an equity stake in Pionyr through their 2020 option-to-acquire agreement.

“We have been highly rigorous and selective in our search for a buyer. Our attraction to Ikena was driven by not only the potential of their targeted oncology programs, but by their company culture and the way their team has managed capital and developed their pipeline,” commented Steven P. James, Pionyr’s Chief Executive Officer. “On behalf of our investors, board of directors, and the Pionyr executive team, I want to thank and congratulate the entire Pionyr team for their efforts.”

About Pionyr Immunotherapeutics

Pionyr’s programs exploit novel target discovery and antibody generation platform technologies to create the next generation of immuno-oncology therapeutics after checkpoint inhibitors. Their initial approach, termed “Myeloid Tuning™,” is designed to enhance the immune system’s anti-tumor response by specifically altering the cellular infiltrate of the tumor microenvironment. Pionyr’s clinical programs, PY314 and PY159, targeting TREM2 and TREM1 respectively, are designed to selectively deplete and in some cases reprogram certain tumor-associated macrophages responsible for immunosuppression. PY314 and PY159 have demonstrated safety alone and in combination with pembrolizumab in Phase 1a/b trials. Pionyr’s third program, PY265 (anti-MARCO) is IND-ready. In July 2020, Pionyr entered into an alliance with Gilead Sciences whereby Gilead acquired a minority interest in the company. The alliance and exclusive option to acquire Pionyr was terminated in 2023. In addition to Gilead, Pionyr’s investors include New Enterprise Associates, OrbiMed, SV Health Investors, Sofinnova Investments, and Vida Ventures.
