Trial Information
Leptomeningeal Metastases (LM) is sometimes referred to as leptomeningeal cancer, leptomeningeal disease, neoplastic meningitis, or meningeal carcinomatosis. This rare but serious condition happens when cancer cells spread to the membranes surrounding the brain and spinal cord. Leptomeningeal Metastases is most commonly found in patients with melanoma, breast, lung, or gastrointestinal cancer. Unfortunately, there are no FDA approved treatments specifically for Leptomeningeal Metastases.
Plus Therapeutics is developing a new targeted radiation therapy, Rhenium (186Re) Obisbemeda, for central nervous system cancers such as Leptomeningeal Metastases. In the U.S. ReSPECT-LM clinical trial, doctors will give Leptomeningeal Metastases 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: December 21, 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: June 30, 2026 (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.
