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
When speaking with your physician, please have the national trial reference number available.
Phase 1 Patients Treated to Date
Phase 2 Patients Treated to Date
- 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: 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.
- 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.

Andrew Brenner, M.D., Ph.D.
UT Health San Antonio
Mays Cancer Center
SPECIALTIES: MEDICAL ONCOLOGY, INTERNAL MEDICINE
A specialist in both breast cancer and malignancies of the brain and spinal cord, Andrew Brenner, M.D., Ph.D., not only focuses on clinical management, but also on the development of novel therapies to treat breast cancers and central nervous system tumors.
A graduate of Texas A&M University, he earned his bachelor’s degree in biochemistry and went on to earn his doctorate in biological science and tumor biology at The University of Texas M.D. Anderson Cancer Center – Science Park. His doctoral thesis focused on the role of the cyclin dependent kinase inhibitor p16INK4a in mammary tumorigenesis and immortilization. Dr. Brenner’s current interests have transitioned from cell cycle to the effect of hypoxia on chemokines and escape from antiangiogenics and the role of obesity in promoting breast tumorigenesis.
Dr. Brenner received his medical degree from the Texas Tech University Health Science Center and completed a residency in internal medicine at Scott and White Hospital in Lubbock. He completed his fellowship in hematology and medical oncology at the UT Health San Antonio.
