"Our data continue to illustrate the importance of clonal neoantigens as targets and show some clinical activity, however our studies in lung cancer and melanoma have not met our goals for commercial viability. We are grateful for the support and commitment of our patients, investigators, employees and shareholders throughout this journey," said Dr Iraj Ali, Chief Executive Officer of Achilles Therapeutics. "We are actively exploring new opportunities to leverage our substantial assets and cutting-edge technology platforms. Our goal remains to drive the development of effective treatments for patients and create long-term value for our shareholders."

In connection with the strategic update, the Company is implementing an employee consultation process in line with UK legislation proposing a workforce reduction and undertaking other cost-cutting measures. The Company recognizes the significant contributions of its talented team and is committed to supporting all employees throughout this transition period. Achilles intends to retain all employees essential for supporting value-realization as part of its strategic review.

As of June 30, 2024, the Company had $95.1 million in cash and cash equivalents.

The full clinical data generated from the Phase I/IIa CHIRON trial in patients with advanced non-small cell lung cancer (NSCLC) and the Phase I/IIa THETIS trial in patients with recurrent or metastatic melanoma will be presented in an upcoming forum.

The process of exploring strategic alternatives may include, but is not limited to, an acquisition, merger, reverse merger, business combination, asset sale, licensing, or other transactions. There can be no assurance that the exploration of strategic alternatives will result in any agreements or transactions, or as to the timing of any such agreements or transactions. Achilles Therapeutics does not intend to discuss or disclose further developments regarding the exploration of strategic alternatives unless and until its Board of Directors has approved a definitive action or otherwise determined that further disclosure is appropriate or required by law.
