, one of the most effective and proven approaches to this is radiation therapy (RT). We are developing a pipeline of products designed to address the limitations of the current standard of cancer therapies. We believe that our product candidates will enable us to deliver cancer treatments that are safer, more reliable and at a greater scale than that of the current standard of care.

Operations to date have focused on continuing our research and development efforts to advance Ropidoxuridine clinical testing and improved drug formulation, to advance HDAC6 inhibitor (SP-2-225) preclinical development and explore new Small Business Innovation Research (SBIR) contract work on predictive biomarkers of radiation response, as well as prostate cell lines for health disparities research. We received SBIR contract funding from the National Institutes of Health (NIH), for the aforementioned projects. The clinical development of Ropidoxuridine has shown drug bioavailability and a maximum tolerated dose has been established for use in Phase II clinical trials. TCG GreenChem, Inc. (“TCG GreenChem”), with whom we have contracted for process research, development and cGMP compliant manufacture of IPdR, has successfully completed the manufacturing campaign for the active pharmaceutical ingredient (API) of Ropidoxuridine for use in the Company’s upcoming Phase II clinical trial in brain cancer patients undergoing radiation therapy. Shuttle also worked with University of Iowa Pharmaceuticals to develop the formulation, produce the capsules, and which have been shipped to Contract Research Organization (CRO) Theradex Oncology for distribution to clinical trial sites. Both activities have now been completed. In addition, Shuttle received approval from the U.S. Food and Drug Administration (FDA) to begin the clinical trial. The FDA made recommendations to expand the clinical trial and the Company agreed with the recommendation. With this change incorporated into the revised protocol, the Company commenced its Phase II clinical study with finalized agreements with all six of the planned site enrollment locations to administer the Phase II clinical trial of Ropidoxuridine and has enrolled the first three patients in October 2024. The radiation biomarker project and the health disparities project have been completed and the Company is following up with plans for clinical validation and potential commercialization. Changes in operational, administrative, legal and professional expenses related to our operations are set forth in more detail in the discussion below.
