Latest News: Positive Data from Ongoing ReSPECT-LM Clinical Trial Presented at Society for Neuro-Oncology Annual Meeting
U.S. Phase 1 Clinical Trial
U.S. Phase 1 Clinical Trial
Leptomeningeal metastases (LM) are a rare but typically fatal complication of advanced cancer in which cancer cells (typically from the breast or lung) spread to the central nervous system (CNS) and are found in either the leptomeninges (membrane surrounding the brain and spinal cord) or cerebrospinal fluid (CSF) (circulates nutrients and chemicals to the brain and spinal cord). Despite affecting over 110,000 people annually in the U.S., highly effective, approved treatments for LM are not available.
Plus Therapeutics is developing Rhenium (186Re) Obisbemeda, an innovative, targeted radiotherapeutic for rare and difficult-to-treat cancers. In the U.S. multi-center ReSPECT-LM Phase 1 clinical trial, Rhenium (186Re) Obisbemeda will be administered through an intraventricular catheter (Ommaya reservoir) in patients with LM. The treatment consists of a single administered dose of Rhenium (186Re) Obisbemeda per patient on an outpatient basis by the clinical trial physician.
NATIONAL TRIAL REFERENCE NUMBER
When speaking with your physician, please have the national trial reference number available.
Patients Treated to Date
- All patients who enroll in the trial will receive medication while on the study.
- All patients will receive a single dose of Rhenium (186Re) Obisbemeda.
- 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.
- Actual Study Start: December 6, 2021
- Estimated Primary Completion: July 30, 2023 (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: December 30, 2023 (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).
Only a qualified healthcare professional can determine whether or not you are eligible to participate in a clinical trial. However, this information may be beneficial in initiating a conversation with your physician. Patient reimbursement of up to $599 for time and travel is available.

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.
