On track to commence Phase II clinical study in the fourth quarter of 2023 for Ropidoxuridine, Shuttle Pharma's lead clinical sensitizer drug candidate.
Successfully completed the initial manufacturing campaign for the active pharmaceutical ingredient (API) of Ropidoxuridine for use in the Shuttle Pharma's upcoming Phase II clinical trial.
Received approval for a Type B pre-IND meeting with the FDA for guidance on the proposed Phase II clinical trial with a goal of receiving written responses from the FDA by September 18, 2023.
Moved into new laboratory and office space to assist in furthering the development Shuttle Pharma's lead drug candidates and accelerate broader diagnostic capabilities on predictive biomarkers.

"We are making significant progress in the advancement of Ropidoxuridine, our lead clinical sensitizer drug candidate, for treatment in brain cancer patients undergoing radiation therapy. During the last few months, we successfully completed the initial manufacturing campaign for the API to be used in the upcoming Phase II clinical trial and received approval from the FDA for a Type B pre-IND meeting to receive guidance on the trial design," commented Shuttle Pharma's Chairman and CEO, Anatoly Dritschilo, M.D. "We expect to receive comments from the FDA by mid-September which would put us in position to initiate the clinical trial in the fourth quarter of this year — a significant inflection point in the development of Ropidoxuridine."

"The move into our new laboratory will accommodate not only our Ropidoxuridine research efforts, but also enhance our ability to establish a CLIA laboratory to advance our diagnostic intellectual property that has been developed with funding from NIH small business innovative (SBIR) research contracts over the past several years, particularly for our predictive biomarker capabilities for prostate cancer patients. We are eligible for NIH SBIR 'bridge' support to assist in funding the advancements of these efforts. Our recently published work in premier cancer journals provides insight into the immune response taking place in patients after radiation therapy for cancer and informs therapeutic strategies for sequencing radiation and immune therapy modalities for cancer treatment," Dr. Dritschilo concluded.
