Official title

A Phase I Study of Anti-CD3 x Anti-Her2/Neu (Her2Bi) Armed Activated T Cells (ATC) in Patients With Breast Cancer Leptomeningeal Metastases

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study uses bi-specific antibody (HER2Bi) armed activated T-cells (HER2 BATs) to target breast cancer cells that have metastasized to the membranes surrounding the brain and spinal cord. This is known as leptomeningeal metastases. Two doses will be evaluated in order to determine a safe dose. Study treatment includes a test dose of HER2 BATs followed by 8 weekly infusions of HER2 BATs at the assigned dose level. Before, during and after study treatment, participants will be monitored objectively by brain MRIs and clinically through physical and neurological exams, and blood and cerebrospinal fluid will be collected to evaluate immune responses.
