Participate in a Leptomeningeal Metastases Clinical Trial

Now Recruiting Patients with LM

Trial Information

Leptomeningeal Metastases (LM), sometimes referred to as leptomeningeal disease, neoplastic meningitis, or meningeal carcinomatosis, is a rare but serious condition that happens when cancer cells spread to the membranes surrounding the brain and spinal cord. LM is most commonly found in patients with melanoma, breast, lung, or gastrointestinal cancer. Unfortunately, there are no FDA approved treatments specifically for LM.

Plus Therapeutics is developing a new targeted radiation therapy, Rhenium (186Re) Obisbemeda, for central nervous system cancers such as LM. In the U.S. ReSPECT-LM clinical trial, doctors will give LM patients a single dose of Rhenium (186Re) Obisbemeda through a small catheter placed under the patient’s scalp. This drug will be administered in less than 5 minutes in a hospital setting and the patient will go home the same day.

The ReSPECT-LM clinical trial is funded, in part, by a $17.6 million grant from the Cancer Prevention & Research Institute of Texas, the second largest public funding source for cancer research in the world.

NATIONAL TRIAL REFERENCE NUMBER

NCT05034497

When speaking with your physician, please have the national trial reference number available.

Patients Treated to Date

Single Group

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.

Phase 1

A Phase 1 study is the first step in testing a new treatment in humans. A phase I clinical trial tests the safety, side effects, best dose, and timing of a new treatment. It may also test how the treatment affects the body. The dose is usually increased a little at a time in order to find the highest dose that does not cause harmful side effects. Phase I clinical trials usually include only a small number of patients who have not been helped by other treatments.

Progress

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).

Plus Therapeutics is evaluating rhenium (186Re) obisbemeda, a novel radiotherapy for patients with Leptomeningeal Metastases in a Phase 1 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.
