A Study of Treatment for Medulloblastoma Using Sodium Thiosulfate to Reduce Hearing Loss
Study Details
Study Description
Brief Summary
This phase III trial tests the addition of sodium thiosulfate to standard of care chemotherapy and radiation therapy in treating patients with low or average risk medulloblastoma (a type of cancer in the brain). Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs 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. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effective at treating the cancer, there are still concerns about the side effects of such treatment. Side effects are unintended problems that arise due to treatment such as learning difficulties, lower amounts of hormones, hearing problems, or other problems in performing daily activities. Patients with medulloblastoma often receive treatment with chemotherapy drugs including cisplatin. Cisplatin may cause hearing loss as a side effect. Previous studies with sodium thiosulfate have shown that it may help reduce or prevent hearing loss caused by cisplatin. This study looks at adding sodium thiosulfate to standard treatment for medulloblastoma (radiation therapy and chemotherapy, including cisplatin) to find out if it reduces hearing loss.

Detailed Description
PRIMARY OBJECTIVES:
-
To evaluate the efficacy of sodium thiosulfate (STS) infusion administered during cisplatin-containing chemotherapy cycles (compared to a historical cohort selected from ACNS0331 which received chemotherapy without STS) in reducing hearing loss in children with newly-diagnosed average-risk medulloblastoma.
-
To estimate and monitor event-free survival (EFS) in this study against a carefully selected cohort from ACNS0331 to guard against loss of efficacy due to STS.
SECONDARY OBJECTIVES:
-
To estimate and monitor overall survival (OS) in this study against a carefully selected control cohort from ACNS0331.
-
To estimate the incidence of ototoxicity-related cisplatin dose modifications in the average-risk cohort.
-
To estimate the incidence of cisplatin-related nephrotoxicity in both the average-risk and low-risk cohorts.
-
To evaluate full scale intelligence neurocognitive outcomes and trajectories of patients with average-risk medulloblastoma treated with STS compared to the control cohort from ACNS0331.
-
To evaluate quality of life and psychosocial outcomes and trajectories of patients with average-risk medulloblastoma treated with STS compared to published norms.
-
To estimate and monitor EFS and OS in patients with low-risk features treated using a reduced craniospinal radiation approach.
-
To evaluate the trajectory of hearing loss in medulloblastoma patients treated with STS.
-
To evaluate household material hardship as a social determinant of neurocognitive, quality of life, and psychosocial outcomes in patients with average-risk and low risk medulloblastoma.
EXPLORATORY OBJECTIVES:
-
To obtain paired blood and tumor tissue to be banked for future biology studies involving comprehensive molecular analysis, including but not limited to whole exome sequencing, ribonucleic acid (RNA) sequencing, and methylation.

OUTLINE:
CHEMORADIOTHERAPY: Patients undergo radiation therapy on weeks 1-7 and receive vincristine intravenously (IV) once weekly on weeks 2-7 in the absence of disease progression or unacceptable toxicity.
MAINTENANCE: Beginning 4 weeks after chemoradiotherapy, patients receive lomustine orally (PO) on day 1 of cycles 1, 2, 4, 5, 7, and 8, cisplatin IV over 6 hours on day 1 of cycles 1, 2, 4, 5, 7, and 8, sodium thiosulfate IV over 15 minutes on day of cycles 1, 2, 4, 5, 7, and 8, cyclophosphamide IV over 30-60 minutes on days 1 and 2 of cycles 3, 6, and 9, and mesna IV over 15-30 minutes three times daily (TID) on days 1 and 2 of cycles 3, 6, and 9. Patients also receive vincristine IV on days 1, 8, and 15 of cycles 1, 2, 4, 5, 7, and 8, and on days 1 and 8 of cycles 3, 6, and 9. Treatment repeats every 6 weeks (cycles 1, 2, 4, 5, 7 and 8) or every 4 weeks (cycles 3, 6, and 9) for up to 9 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for years 1-2, every 6 months for years 3-4, and then annually for years 5-10.

Primary Outcome Measures
- Percentage of patients with >= grade 2 hearing loss [At 4 weeks after the last dose of cisplatin]
Will report the percentage of patients with >= grade 2 hearing loss in the better ear at 4 weeks after the last dose of cisplatin in ACNS2031 and will compare it with the rate from ACNS0331 historical cohort using Fisher's exact test.
- Event-free survival (EFS) [From initiation of the protocol treatment to the occurrence of disease progression, disease recurrence, death from any cause, or occurrence of a second malignant neoplasm, assessed up to 10 years]
Will estimate the EFS distribution using Kaplan-Meier method.
Secondary Outcome Measures
- Overall survival (OS) [Up to 10 years]
Will calculate the OS distribution using Kaplan Meier method.
- Incidence of ototoxicity-related cisplatin dose modifications in the average-risk cohort [Up to 10 years]
Will be calculated by dividing the total number of ototoxicity-related cisplatin dose modifications by the cumulative dose of cisplatin. Summary statistics including mean, standard deviation (SD), median and range will be used to summarize the data by cohorts.
