Glioblastoma clinical trials, in English

Glioblastoma (GBM) studies may enroll at first diagnosis, at recurrence, or around radiation. MGMT, IDH, and steroid dose often appear in eligibility. A rewrite on this page never replaces the neurosurgery or oncology team who must confirm whether a site is open. Sourced from ClinicalTrials.gov. Not a recommendation to join any study.

Collection of Blood and Urine Samples in Patients Receiving Radiation Therapy for Glioblastoma Multiforme

This study will collect blood and urine samples from patients undergoing radiation therapy for glioblastoma multiforme (a type of brain tumor) to investigate the effects of this treatment on blood cells and certain proteins. The information from this study may help scientists develop new tests to measure radiation exposure and find new ways to treat cancer with radiation, and help determine which kinds of patients or tumors respond better to radiation therapy.

Phase 2: testing Pembrolizumab (Keytruda) for Metastatic Colorectal Cancer

Background: The NCI Surgery Branch has developed an experimental therapy that involves taking white blood cells from patients' tumors, growing them in the laboratory in large numbers, and then giving the cells back to the patient. These cells are called Tumor Infiltrating Lymphocytes, or TIL and we have given this type of treatment to over 200 patients with melanoma.

Phase 1: testing Indoximod for Ependymoma

Recent lab-based discoveries suggest that IDO (indoleamine 2,3-dioxygenase) and BTK (Bruton's tyrosine Kinase) form a closely linked metabolic checkpoint in tumor-associated antigen-presenting cells. The central clinical hypothesis for the GCC2020 study is that combining ibrutinib (BTK-inhibitor) with indoximod (IDO-inhibitor) during chemotherapy will synergistically enhance anti-tumor immune responses, leading to improvement in clinical response with manageable overlapping toxicity.

FAQ: Glioblastoma trials

How do I find recruiting Glioblastoma clinical trials?

This hub lists 34 recruiting Glioblastoma studies from a ClinicalTrials.gov snapshot, rewritten in plain English. Each card links to its NCT record. You can also search the official registry for “glioblastoma” at https://clinicaltrials.gov/search?cond=glioblastoma.

What does a Glioblastoma trial page on PlainTrials include?

A phase explainer, a plain-English summary grounded in the brief summary, inclusion/exclusion extracted from the public eligibility block, sponsor name, and any central contact the sponsor published. It is not a match to a trial.

Where are Glioblastoma studies located in this snapshot?

Sites that appear on these records include New York, New York; Los Angeles, California; Boston, Massachusetts; Houston, Texas; San Francisco, California. A city on a record is not a guarantee that the site is taking new patients this week — call the NCT contact.

Can PlainTrials tell me if I qualify for a Glioblastoma study?

No. Eligibility is decided by the study team using the protocol, labs, and consent. Our “who it is for” list is a readable extract of public inclusion text only.
