Study Summary

This trial is investigating if the drug Temozolomide can be an effective treatment for SDH-Mutant/Deficient Gastrointestinal Stromal Tumor, which currently doesn't have any known effective treatments.

Who is the study for?
This trial is for male and female patients with a specific type of cancer called SDH-Mutant/Deficient Gastrointestinal Stromal Tumor (GIST) that cannot be removed by surgery or has spread. Participants must have recovered from previous treatments, not have severe diseases like uncontrolled heart conditions, and agree to use contraception. Pregnant or breastfeeding women and those unable to take oral medication are excluded.Check my eligibility
What is being tested?
The study is testing the effectiveness of Temozolomide (TMZ), an FDA-approved drug for certain brain cancers but considered experimental for GIST. The goal is to see if TMZ can improve outcomes in patients with this particular subtype of GIST where other therapies are ineffective.See study design
What are the potential side effects?
Temozolomide may cause side effects such as fatigue, nausea, vomiting, constipation, loss of appetite, headache, seizures or convulsions due to its impact on the brain and nervous system; it might also lower blood cell counts increasing infection risk.

Experimental Treatment
Group I: TMZ 85 mg/m2 mg orallyExperimental Treatment1 Intervention
TMZ 85 mg/m2 mg orally once for 21 days followed by 7 days without treatment in 28 day cycles. Treatment will continue for 6 months (with option to continue if benefiting treatment) or until disease progression or unacceptable toxicity (whichever occurs first). All patients will have regular evaluations for assessment of safety parameters. Temozolomide dose may be held and/or modified for the management of adverse treatment effects according to pre-specified criteria. Patients will have radiographic imaging (CT or MRI) every 8 weeks to assess tumor resection. An end of treatment visit for clinical evaluations and safety assessments will be performed approximately 28 days after the last dose of study drug. Patients discontinuing study treatment will be followed every 3-6 months for disease recurrence and survival.
