Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are on another investigational drug, you must stop it at least 30 days before starting the trial treatment.

What data supports the effectiveness of the drug Temsirolimus for brain tumors?

Temsirolimus, an mTOR inhibitor, has shown promise in treating various cancers, including breast cancer and renal cell carcinoma, with response rates of 10-20% in some studies. It is also being evaluated for melanoma and has shown effectiveness in mantle-cell lymphoma with a 40% response rate.12345

Is temsirolimus safe for humans?

Temsirolimus has been studied in various clinical trials, showing some side effects like rash, mouth sores, and fatigue. In combination with other drugs, it can cause low platelet counts, which are cells that help blood clot. The maximum tolerated dose varies depending on the formulation and combination with other treatments.12467

How is the drug Temsirolimus unique for treating brain tumors?

Temsirolimus is unique because it is an mTOR inhibitor, which means it blocks a specific protein that helps cancer cells grow. It is given through an infusion (a slow injection into a vein) and is being studied for its potential to treat brain tumors, which is different from many standard treatments that might not target this specific pathway.12589

What is the purpose of this trial?

This is a single-center, open-label, dose-escalating Phase 0 trial that will enroll participants with a confirmed diagnosed recurrent high-grade glioma (grade 3 or 4 per WHO criteria) targeting the mTOR pathway. Eligible participants will be administered a single infusion of temsirolimus through super-selective intra-arterial infusion or intravenous infusion. Participants will receive the study drug administration on the same day as the planned surgical resection of the tumor.

Exclusion Criteria

Participant has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, active infection, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment [e.g. estimated creatinine clearance]
Pregnancy or lactation
Known hypersensitivity to temsirolimus or its metabolites, polysorbate 80, or to any other component of temsirolimus

Treatment Details

Interventions

  • Temsirolimus
Trial Overview This trial tests Temsirolimus delivered directly into the artery feeding the tumor or through an IV on the same day as surgery to remove the tumor. It's for those whose tumors show certain changes in their mTOR pathway and is designed to find out how different doses affect patients.

Findings from Research

In a study involving 63 patients with advanced cancer, temsirolimus was found to be generally well tolerated, with a maximum tolerated dose established at 15 mg/m²/day for heavily pretreated patients and 19 mg/m²/day for minimally pretreated patients.
The treatment showed promising preliminary antitumor activity, with one patient achieving a confirmed partial response lasting 12.7 months, and several others showing stable disease for over 24 weeks.
A phase I and pharmacokinetic study of temsirolimus (CCI-779) administered intravenously daily for 5 days every 2 weeks to patients with advanced cancer.Hidalgo, M., Buckner, JC., Erlichman, C., et al.[2014]
In a Phase 1 study involving 10 Japanese patients with advanced solid tumors, the maximum-tolerated dose of temsirolimus was determined to be 15 mg/m², with significant toxicities observed at higher doses, including Grade 3 stomatitis and diarrhea.
Temsirolimus demonstrated dose-dependent pharmacokinetics, with peak blood concentrations of both temsirolimus and its active metabolite sirolimus increasing with higher doses, indicating a need for careful dose management in future studies.

Temsirolimus, an intravenous drug that targets the mTOR kinase, shows immunosuppressive and antiproliferative effects, particularly in cancers like breast cancer, glioblastoma, and renal cell carcinoma, with response rates between 10% to 20%.
In mantle-cell lymphoma, temsirolimus has a higher response rate of 40%, indicating its potential effectiveness, especially when used in combination with chemotherapy.
