Nedisertib and Radiation Therapy, Followed by Temozolomide for the Treatment of Patients With Newly Diagnosed MGMT Unmethylated Glioblastoma or Gliosarcoma

• Status: Recruiting
• Trial end date: 2023-10-30
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial investigates the side effects and best dose of nedisertib, and to see how well it works in combination with radiation therapy in treating patients with newly diagnosed MGMT unmethylated glioblastoma or gliosarcoma. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Nedisertib may further stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nedisertib with radiation therapy may work better than radiation therapy alone in treating patients with glioblastoma or gliosarcoma.

• Male subjects should agree to use an adequate method of contraception during the course of the study

• STAGE I: In the case stage I patients need resection as determined by the treating physicians during or after completion of radiation therapy (RT) and that pathology of resected lesion is not consistent with recurrent GBM, the patient can continue on the study (complete 6 weeks of RT + M3814) if deemed appropriate by the treating physicians. The tissue obtained in such circumstances will be analyzed as in Stage II subjects. However, these cases will not count towards the 5 patients who will be enrolled during Stage II. These patients will contribute to the correlative endpoints detailed above and ORR, OS, and PFS as Stage II patients

• STAGE II: Patients meet above criteria, would benefit from further non-urgent surgical resection of at least one enhancing lesion per the treating physician, and would provide consent to undergo surgery after treatment with RT and M3814

Exclusion Criteria:

• Has received prior interstitial brachytherapy, implanted chemotherapy, or therapeutics delivered by local injection or convection enhanced delivery. Prior treatment with Gliadel wafers and laser interstitial thermal therapy (LITT) will be excluded. Active treatment with the tumor treating filed devices such as Optune will be excluded

• Currently participating or previously participated in any other newly diagnosed GBM therapeutic trials

• History of MGMT methylated status performed at any CLIA certified laboratory

• Any serious medical condition that interferes with adherence to study procedures

• Malignancies other than the disease under study within 5 years prior to day 1 of the study, with the exception of those with a negligible risk of metastasis or death and with expected curative outcome (such as adequately treated carcinoma in situ of the cervix, basal or squamous cell skin cancer, localized prostate cancer treated surgically with curative intent, or ductal carcinoma in situ treated surgically with curative intent) or undergoing active surveillance per standard-of-care management (e.g., chronic lymphocytic leukemia Rai stage 0, prostate cancer with Gleason score =< 6, and prostate-specific antigen [PSA] =< 10 mg/mL, etc)

• Subjects at increased risk for radiation toxicities, such as known active collagen vascular disease (example; scleroderma, Sjogren's disease, etc) or other inherited radiation hypersensitivity syndromes (example; Gorlin syndrome, Fanconi anemia, ataxia-telangiectasia, etc.)

• Active difficulty swallowing, malabsorption or other chronic gastrointestinal disease or conditions (including pancreas deficiency requiring Creon therapy) that may hamper compliance and/or absorption of M3814
