TARGETING RADICAL ADVANCEMENT IN NEXT GENERATION CANCER RADIATION

Shuttle Pharmaceuticals’ Ropidoxuridine Aims to Make Cancer Radiation Therapy Work Better: Much Better!
-
Radiation therapy is commonly used to treat cancer. The Radiotherapy Market size was valued at around USD 7 billion in 2023
-
Radiation dosage and efficacy is limited by tolerance to radiation of healthy cells that are adjacent to cancer cells.
-
There is strong supporting evidence that Ropidoxuridine makes cancer cells more sensitive to radiation therapy. See charts below.
-
By making cancer cells more sensitive to radiation, Shuttle’s Ropidoxuridine has thus far been shown to make radiation work better with fewer side effects. Shuttle plans to demonstrate further proof in the upcoming P2 trial for Glioblastoma patients.
-
There is a large and urgent need for a drug like Ropidoxuridine that can make cancer cells more sensitive to radiation treatment. If Shuttle’s clinical trials are successful, Ropidoxuridine could be become a new hope for cancer patients and a new standard of treatment for several cancers.

On October 1, 2024, Shuttle Pharmaceutical Holdings, Inc. shares closed at $1.21 with a market capitalization of about $3 million.

Ropidoxuridine Makes Radiation Therapy More Effective
Although radiation therapy is commonly used to treat cancer, its dosage is limited by healthy cells that are adjacent to the cancer cells.
The following slide supports the efforts of Shuttle Pharmaceuticals to develop and bring Ropidoxuridine to market. The slides address the Mechanism of Action for Ropidoxuridine, and demonstrate a significant increase in the median survival in grade 3 and 4 Anaplastic astrocytomas and Glioblastoma Multiforme patients.

Management
A review of Shuttle Pharmaceuticals management demonstrates deep experience in the business of cancer treatments and a caliber of excellence that is sure to gain attention from investors and potential partners even in a crowded field of competitors that are all vying for attention to their various efforts.


Shuttle Pharmaceuticals is Advancing Ropidoxuridine to Phase 2 Clinical Trial
Shuttle Pharmaceuticals recently announced Shuttle Pharma Expands Clinical Trial Site Enrollment for Phase 2 of Ropidoxuridine for Treatment of Patients with Glioblastoma. Ropidoxuridine (IPdR) is Shuttle Pharma's lead candidate radiation sensitizer for use in combination with RT to treat brain tumors (glioblastoma), a deadly malignancy of the brain with no known cure. Shuttle has received Orphan Drug Designation from the FDA, providing potential marketing exclusivity upon first FDA approval for the disease.
The Phase 2 clinical trial will enroll patients with the most aggressive brain tumors out there – IDH wild-type, methylation negative glioblastoma. Presently, radiation is the only approved standard of care for this particular group of patients, with more than half of the patients surviving for less than 12 months after diagnosis. Shuttle Pharma’s Phase 2 clinical trial will consist initially of 40 patients randomized into two different doses (20 @ 1,200 mg/day and 20 @ 960 mg/day) to determine an optimal dose. Once the Company determines the optimal dose, it will then add an additional 14 patients on the optimal dosage allowing for the achievement of statistical significance with the end point being that of survival as compared to historical controls. The Company expects the trial to be completed over a period of 18 to 24 months.
An estimated 800,000 patients in the US are treated with radiation therapy for their cancers yearly. According to the American Cancer Society and the American Society of Radiation Oncologists, about 50% are treated for curative purposes and the balance for therapeutic care. The market opportunity for radiation sensitizers lies with the 400,000 patients treated for curative purposes, with this number expected to grow by more than 22% over the next five years.
In addition to Ropidoxuridine, Shuttle is developing other very promising treatment and diagnostics and is seeking the following pathways:

Conclusion
Shuttle Pharmaceuticals represents a compelling investment opportunity within the oncology sector. The innovative potential of Ropidoxuridine to enhance chemotherapy effectiveness, combined with a favorable market landscape and strategic positioning, sets the stage for substantial upside. While the associated risks cannot be overlooked, the combination of promising clinical data, an increasing demand for novel cancer therapies, and a supportive regulatory environment positions Shuttle as a strong candidate for success.
As investors seek opportunities in biotech, Shuttle Pharmaceuticals offers a distinctive value proposition in a rapidly evolving market. The potential rewards could outweigh the risks, making this an intriguing consideration for long-term growth.
