Trial Information
The purpose of the ReSPECT-GBM Clinical Trial is to assess the safety, tolerability, and distribution of a new medication, rhenium (186Re) obisbemeda, in adults with recurrent glioblastoma after standard surgical, radiation, and/or chemotherapy treatment. ReSPECT-GBM is supported by the U.S. National Institutes of Health / National Cancer Institute.
NATIONAL TRIAL REFERENCE NUMBER
NCT01906385
When speaking with your physician, please have the national trial reference number available.
Phase 1 Patients Treated to Date
29
Phase 2 Patients Treated to Date
19
Single Group
- All patients who enroll in the trial will receive medication while on the study.
- All patients will receive a single treatment of rhenium (186Re) obisbemeda.
Phase 1/2
- Phase 1: A Phase 1 study of a new medication is usually the first that involves human volunteers who have the disease or condition the investigational medicine is designed to treat. The primary objective of Phase 1 studies is to identify the highest dose of the new medication that can be safely given without serious side effects.
- Phase 2: If a new medication is found to be reasonably safe in a Phase 1 study, it can then be evaluated in a Phase 2 study to determine if it works. Doctors will assess whether the new medication provides a specific benefit or response, such as tumor shrinkage, improved quality of life, or longer patient survival.
Progress
- Actual Study Start: June 3, 2015
- Estimated Primary Completion: January 2025 (the date that the last participant in a clinical study was examined or received an intervention and that data for the primary outcome measure were collected)
- Estimated Study Completion: January 2025 (the date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events, that is, the last participant’s last visit).
Plus Therapeutics is evaluating rhenium (186Re) obisbemeda, a novel radiotherapy for brain cancer patients, in the U.S. NIH-supported ReSPECT-GBM Phase 2 clinical trial.

- Median overall survival (mOS) in 15 patients with recurrent glioblastoma (rGBM) from the Phase 2 study is 13 months, which is 63% better than current standard of care (bevacizumab monotherapy) of 8 months; 9 of the 15 patients remain alive
- Median progression free survival (mPFS) is 11 months, compared to SOC at 4 months
- Rhenium (186Re) Obisbemeda continues to demonstrate a favorable safety profile, despite delivering up to 20x the dose of radiation (up to 740 Gy) typically delivered by external beam radiation therapy (EBRT) for rGBM patients (up to 35 Gy)
- Imaging data presented by Andrew Brenner, MD, PhD is consistent with the efficacy signal of Rhenium (186Re) Obisbemeda in rGBM
