Superselective Intra-arterial Cerebral Infusion of Temsirolimus in HGG

May 11, 2026 updated by: Nader Sanai

A Phase 0, Single-center, Open-label, Dose-escalating Trial Using Super-selective Intra-arterial Infusion of a Single Dose of Temsirolimus for the Treatment of Recurrent High-grade Glioma

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Histologically diagnosed high-grade glioma (Grade 3 or 4 per 2021 WHO criteria) in the frontal lobe.

  • For females of reproductive potential: use of highly effective contraception and agreement to use such a method during study participation until the end of treatment administration and for 3 months after the last dose of study drug.
  • For males of reproductive potential: use of condoms or other methods to ensure effective contraception with partner until the end of treatment administration and for 3 months after the last dose of study drug.
  • Agreement to adhere to Lifestyle Considerations throughout study duration

Exclusion Criteria:

  • Past medical history of interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease.
  • Pregnancy or lactation.
  • Known hypersensitivity to temsirolimus or its metabolites, polysorbate 80, or to any other component of temsirolimus.
  • 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]
  • Received a live vaccination or is in close contact with someone who received a live vaccination within 28 days of the start of study treatment
  • Treatment with another investigational drug or other intervention within 30 days prior to the planned treatment Day 1.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Tumor pharmacokinetics (PK) of temsirolimus
Time Frame: Day 1 (Intraoperative)
Total and unbound temsirolimus concentration in tumor tissue.
Day 1 (Intraoperative)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame
Pharmacodynamic effects of temsirolimus
