• Updated corporate slide presentation to highlight the opportunity for both Shuttle Pharma's radiation sensitizer portfolio as well as the diagnostic subsidiary.

"We achieved a significant milestone in January 2024 with the receipt of the 'Safe to Proceed' letter from the U.S. Food and Drug Administration (FDA) to commence Ropidoxuridine's Phase 2 clinical trial," stated Shuttle Pharma's Chairman and CEO, Anatoly Dritschilo, M.D. "We are currently finalizing site enrollment with 'first patient, first dose' expected in the second quarter of 2024. The results of this Phase 2 clinical trial will be important as we look to leverage radiation sensitizers to increase cancer cure rates, prolong patient survival, and improve the quality of life for patients suffering from glioblastoma.

"Beyond our focus on radiation sensitizers through both our Ropidoxuridine and HDAC6 development, we also announced the formation of Shuttle Diagnostics, which is focused on developing pretreatment predictive blood tests for prostate cancer patients. These tests will allow for the assessment of risk for cancer treatment success or failure, while informing therapeutic decision making and follow-up management. In 2019, the estimated global prostate cancer diagnostic market was $2.83 billion, however, none of the currently available tests are predictive of success of a specific treatment. We aim to meet this key unmet need for a minimally invasive diagnostic test that provides the clinician and patient with a measurement of the potential success of RT for their cancer treatment.

"We expect the coming few months will be filled with key developments and milestones, including the commencement of our Phase 2 clinical trial for Ropidoxuridine for treatment of patients with glioblastoma and the advancement of our opportunity within diagnostics. Our team is laser-focused on execution of the key deliverables that we believe will drive value for both patients and shareholders," Dr. Dritschilo concluded.
