Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this pre-approval access program is to give talquetamab monotherapy (treatment with single drug) to participants with relapsed or refractory multiple myeloma (a type of cancer that begins in plasma cells \[white blood cells that produce antibodies\] which has returned or difficult to treat) who have relapsed on or are refractory to all locally available and clinically appropriate treatment and who are not eligible for a clinical trial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Talquetamab (JNJ-64407564) is a humanized immunoglobulin G4 proline, alanine, alanine (IgG4PAA) bispecific antibody designed to target G-Protein Coupled Receptor (5DGPRC5D) and cluster of differentiation 3 (CD3). Redirecting T-cells to a tumor surface antigen using bispecific antibody approaches may be an effective means to harness the immune system to destroy cancer cells expressing GPRC5D and create meaningful and long-lasting clinical responses. Talquetamab is supplied as single-dose Investigational Product (IP) vials for subcutaneous administration. Safety assessments will include adverse events, serious adverse events, adverse drug reactions, and special situations which will be reported during the duration of the pre-approval access program.
