Study Summary

This trialtests adding a drug to standard treatment for a type of brain cancer to reduce side effects, like hearing loss.

Who is the study for?
This trial is for children and young adults aged 3 to 21 with newly diagnosed medulloblastoma, a brain cancer. They must have normal kidney and liver function, no prior tumor-directed therapy except surgery/corticosteroids, and not be pregnant or breastfeeding. Participants need confirmed negative spinal fluid tests for metastasis, controlled seizures if present, and normal hearing in at least one ear.Check my eligibility
What is being tested?
The study examines whether sodium thiosulfate can reduce cisplatin-induced hearing loss in patients with average-risk medulloblastoma during standard treatment including surgery, chemotherapy (cisplatin), and radiation. It also explores less intense therapy's effectiveness for low-risk patients to minimize side effects.See study design
What are the potential side effects?
Possible side effects include hearing loss from cisplatin; nausea, hair loss from chemotherapy; skin irritation from radiation; allergic reactions to sodium thiosulfate or other drugs used like mesna.

Experimental Treatment
Group I: Treatment (chemoradiotherapy, maintenance)Experimental Treatment9 Interventions
CHEMORADIOTHERAPY: Patients undergo radiation therapy on weeks 1-7 and receive vincristine 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 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 1 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 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.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Does this experiment accept participants of legal age?

"Patients that fall between the ages of 3 to 21 years old are eligible for this trial."

Answered by AI

What qualifications are needed to participate in this medical experiment?

"In order to be considered for this trial, the patient must have suffered auditory impairment due to a pharmaceutical drug and fall between 3-21 years of age. A total of 225 participants are required before completion."

Answered by AI

Has the FDA sanctioned chemoradiotherapy and maintenance as viable treatments?

"Treatment (chemoradiotherapy, maintenance) received a score of 3 on our safety scale because the Phase 3 trial has gathered evidence in its favour and multiple rounds of data have indicated that the intervention is safe."

Answered by AI

What is the maximum quota for enrollees of this trial?

"Affirmative, information available on clinicaltrials.gov affirms that recruitment is ongoing for this medical investigation. It was first announced on December 9th 2022 and most recently updated January 18th 2023. The trial requires the participation of 225 patients from a single location."

Answered by AI

Is the opportunity to participate in this trial still available?

"Yes, the details on clinicaltrials.gov demonstrate that this medical trial is currently enrolling individuals. It was first introduced to the public on December 9th 2022 and has been updated as recently as January 18th 2023. The study aims to recruit 225 subjects from a single site."

Answered by AI

What is the primary goal of this experimental research endeavor?

"The primary outcome of this trial, which will be evaluated over the course of four weeks after first dose of CDDP is Event-free Survival (EFS). Secondary objectives encompass gauging the incidence rate of cisplatin-related nephrotoxicity in both average and low risk cohorts, quantifying median summary statistics including median and range by cohort group, identifying full scale intelligence neurocognitive outcomes as well as longitudinal trajectories for patients with average-risk medulloblastoma compared to a control cohort from ACNS0331 using Wechsler Intelligence Scale Vocabulary and Block Design subtest. Lastly, estimated EFS distributions for"
