A Phase I/II Study of Zotiraciclib for Recurrent Malignant Gliomas With Isocitrate Dehydrogenase 1 or 2 (IDH1 or IDH2) Mutations
Purpose
Background: Diffuse gliomas are tumors that affect the brain and spinal cord. Gliomas that develop in people with certain gene mutations (IDH1 or IDH2) are especially aggressive. Better treatments are needed. Objective: To see if a study drug (zotiraciclib) is effective in people with recurrent diffuse gliomas who have IDH1 or IDH2 mutations. Eligibility: People aged 15 years and older with diffuse gliomas that returned after treatment. They must also have mutations in the IDH1 or IDH2 genes. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of their heart function. They will have an MRI of their brain. A new biopsy may be needed if previous results are not available. Zotiraciclib is a capsule taken by mouth with a glass of water. Participants will take the drug at home on days 1, 4, 8, 11, 15, and 18 of a 28-day cycle. They may also be given medications to prevent side effects of the study drug. The schedule for taking the study drug may vary for participants who will undergo surgery. Participants will be given a medication diary for each cycle. They will write down the date and time of each dose of the study drug. Participants will visit the clinic about once a month. They will have a physical exam, blood tests, and tests to evaluate their heart function. An MRI of the brain will be repeated every 8 weeks. Participants may remain in the study for up to 18 cycles (1.5 years). ...

Exclusion Criteria
- More than one prior disease relapse (WHO grade 3-4) or more than two prior disease relapses (WHO grade 2) for Phase II only. For Phase I enrollment, there are no limits on the number of prior recurrences. - Prior therapy with: - any investigational agent (including IDH mutant inhibitor) and/or standard of care cytotoxic therapy within 28 days prior to treatment initiation - vincristine within 14 days prior to treatment initiation - nitrosoureas within 42 days prior to treatment initiation - procarbazine within 21 days prior to treatment initiation - non-cytotoxic agents, e.g., interferon, tamoxifen, thalidomide, cis-retinoic acid, within 7 days prior to treatment initiation - surgery within 14 days prior to treatment initiation - radiation therapy within 30 days prior to treatment initiation - bevacizumab for tumor treatment. Note: participants who received bevacizumab for symptom management, including but not limited to cerebral edema, or pseudo progression can be enrolled - Prolonged QTc >470ms as calculated by correction formula on screening electrocardiogram (ECG) (QTCf can be used; QTCb can be used for participants with sinus bradycardia) ) - Prior invasive malignancies within the past 3 years prior to study treatment initiation (with the exception of non-melanoma skin cancers, carcinoma in situ of the cervix, melanoma in situ, or any localized cancer for whom the systemic standard of care therapy is not required) - History of allergic reactions attributed to compounds of similar chemical composition to zotiraciclib, such as flavopiridol - Pregnancy (confirmed with beta-HCG serum or urine pregnancy test performed at screening) - Uncontrolled intercurrent illness or social situations that would limit compliance with study requirements - Uncontrolled primary diabetes mellitus

Detailed Description
Background: - Zotiraciclib is a multi-kinase inhibitor that has been shown to have anti-glioma effects through transcriptional suppression, mitochondrial dysfunction, and adenosine 5'-triphosphate (ATP) reduction in glioblastoma in our preclinical studies - Zotiraciclib is orally administered and likely penetrates the blood brain barrier (BBB). There has been a clinical experience in using zotiraciclib as a single agent and in combination with other chemotherapy agents in cancers, including malignant gliomas - Our phase I study of zotiraciclib and temozolomide (TMZ) in recurrent high-grade astrocytomas determined the maximum tolerated dose (MTD) of zotiraciclib in combination with TMZ and demonstrated the safety of the treatment in recurrent high-grade glioma patients - Preliminary efficacy analysis of Phase I demonstrated an improved response to zotiraciclib in combination with TMZ in IDH-mutant gliomas compared to the IDH-wildtype counterpart - A selective vulnerability to zotiraciclib as a single agent was demonstrated in the preclinical models of IDH-mutant gliomas Objectives: - Phase I: To estimate recommended phase II dose (RP2D) of zotiraciclib - Phase II: To determine 12-months progression free survival (PFS) in participants with recurrent glioma, IDH1/2-mutant, World Health Organization (WHO) grade 3 treated with zotiraciclib in comparison with the established brain tumor database matched for tumor molecular characteristics and clinical prognostic factors Eligibility: - Age >=15; Karnofsky performance status (KPS) >=70% - Histological confirmation of diffuse glioma, WHO grades 2-4 with IDH1/2 mutation status confirmed by DNA sequencing - Have recurrent disease - Have prior treatment of radiation and/or conventional chemotherapies - No prior use of bevacizumab as a treatment for a brain tumor Design: - This is a phase I/II study to evaluate the safety and efficacy of zotiraciclib as a single agent in recurrent IDH-mutant gliomas. - Initially, 9-24 participants (Cohort 1) will be assigned to Phase I to estimate recommended phase 2 dose (RP2D) of zotiraciclib. - Once RP2D is estimated, we will start enrollment into cohorts for Phase II, non-surgical participants (Cohorts 2-4), and surgical (Cohort 5). This trial plans to enroll up 64 evaluable participants. - Drug will be administered on days 1, 4, 8, 11, 15, 18 in cycles of 28 days for a maximum of 18 cycles. Starting dose is 200 mg. In the case that 200 mg is not tolerable, a lower dose 150 mg, will be evaluated. If 200 mg is tolerated well, a higher dose level will be evaluated at 250 mg. - Participants in the surgical cohort will get an additional single pre-treatment with one dose of study drug at the RP2D on Day 1 of Cycle 0, followed by brain tumor biopsy or surgical resection within 24 hours on Day 2 of Cycle 0. Approximately 2-4 weeks after surgery or biopsy participants in this Cohort will continue treatment with the study drug and start Day 1 of Cycle 1.
