Shuttle Pharma Expands Clinical Trial Site Enrollment for Phase 2 of Ropidoxuridine for Treatment of Patients with Glioblastoma
Rhea-AI Summary
Shuttle Pharmaceuticals Holdings, Inc. (Nasdaq: SHPH) has expanded its Phase 2 clinical trial for Ropidoxuridine, a radiation sensitizer for treating glioblastoma patients. The company has added two more site locations, bringing the total to four out of six planned sites ready to enroll patients. These include UVA Cancer Center, John Theurer Cancer Center, Allegheny Health Network Cancer Institute, and Miami Cancer Institute.
The trial targets IDH wild-type, methylation negative glioblastoma patients, aiming to improve outcomes for this aggressive brain cancer. Ropidoxuridine has received Orphan Drug Designation from the FDA. The study will initially enroll 40 patients, testing two dosage levels, with an additional 14 patients added later to achieve statistical significance. Shuttle Pharma expects the trial to be completed in 18 to 24 months.
Positive
- Expansion of Phase 2 clinical trial sites to four out of six planned locations
- Orphan Drug Designation received from FDA for Ropidoxuridine
- Potential market of 400,000 patients treated for curative purposes, expected to grow by 22% in five years
- Trial design allows for determination of optimal dosage and statistical significance
Negative
- Long trial duration of 18 to 24 months
- patient pool with specific glioblastoma type (IDH wild-type, methylation negative)
- Current survival rate for target patient group is less than 12 months after diagnosis
Insights
The expansion of clinical trial sites for Shuttle Pharma's Phase 2 study of Ropidoxuridine in glioblastoma treatment is a significant development. With four out of six planned sites now ready to enroll patients, including prestigious cancer centers, this could accelerate patient recruitment and data collection. The focus on IDH wild-type, methylation negative glioblastoma patients is crucial, as this subgroup has treatment options and poor prognosis.
The two-dose randomization (1,200 mg/day vs. 960 mg/day) followed by an expansion cohort is a smart trial design. It allows for dose optimization and potentially achieving statistical significance in survival outcomes. However, the 18-24 month timeline for trial completion seems optimistic given the typically slow progression of glioblastoma trials. Investors should monitor enrollment rates and any interim analyses carefully.
Shuttle Pharma's approach with Ropidoxuridine as a radiation sensitizer for glioblastoma is intriguing. The Orphan Drug Designation provides potential market exclusivity, which is valuable in this niche. Targeting IDH wild-type, methylation negative glioblastoma is strategic, as these patients have the worst prognosis and options beyond radiation therapy.
The survival endpoint comparison to historical controls is appropriate but challenging. Glioblastoma treatment has seen incremental improvements, so ensuring the historical data is recent and matched will be important for meaningful results. The potential to improve outcomes in a disease with less than 12-month median survival is significant. However, safety will be paramount, as increasing radiation sensitivity could potentially exacerbate side effects in healthy brain tissue.
Shuttle Pharma's focus on radiation sensitizers targets a substantial market. With 400,000 patients treated annually for curative purposes and projected 22% growth over five years, the potential is significant. However, competition and market penetration will be key challenges.
The company's strategy to improve radiation therapy outcomes could position it well in the oncology market. The Orphan Drug Designation provides both market protection and potential for expedited review. Investors should note that while the glioblastoma market is relatively small, success here could pave the way for broader applications in other cancers treated with radiation. The company's pipeline and ability to expand indications will be important for long-term growth potential.
GAITHERSBURG, Md., Sept. 16, 2024 (GLOBE NEWSWIRE) -- Shuttle Pharmaceuticals Holdings, Inc. (Nasdaq: SHPH) (“Shuttle Pharma”), a discovery and development stage specialty pharmaceutical company focused on improving outcomes for cancer patients treated with radiation therapy (RT), announced today it has entered into agreements with two additional site locations to administer the Phase 2 clinical trial of Ropidoxuridine for the treatment of patients with glioblastoma. Four of the planned six trial sites are now prepared to enroll patients in the clinical trial, including the UVA Cancer Center, John Theurer Cancer Center at Hackensack University Medical Center, Allegheny Health Network (AHN) Cancer Institute, and Miami Cancer Institute, part of Baptist Health South Florida.
“I am pleased to report yet another key milestone in the advancement of our Phase 2 clinical trial for the treatment of patients with glioblastoma, having successfully onboarded two additional nationally recognized cancer centers,” commented Shuttle Pharma's Chairman and CEO, Anatoly Dritschilo, M.D. “Each of the four initial locations have completed site initiation visits and are fully ready to begin treating patients, with the final two sites set to come on board in the coming weeks. The six universities and hospitals we have selected to participate in this important clinical trial are those we deem to be most likely to treat IDH wild-type, methylation negative glioblastoma patients, the target of the clinical trial, which should allow for more rapid enrollment of the Phase 2 trial.”
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
