New cancer treatment destroys bone marrow cancer cells with 73% success rate in trials

Even in individuals whose malignancy was resistant to every licenced treatment for multiple myeloma, the efficacy of the over-the-counter immunotherapy known as talquetamab was observed. Unlike other authorised treatments, it targets a receptor called GPRC5D that is expressed on the surface of cancer cells.

Accordingly, over a third of these patients can anticipate a new beginning, according to Ajai Chari, MD, Director of Clinical Research in the Multiple Myeloma Program at The Tisch Cancer Institute and lead author of both studies.

Between January 2018 and November 2021, 232 participants from various cancer centres around the world were enrolled in this Phase 1 clinical research. Future trials will concentrate on doses only supplied under the skin either weekly or every other week, given that patients received a variety of doses of the medication either intravenously or injected under their skin.

The medication binds to both T cells and multiple myeloma cells and gives the T cells instructions to kill multiple myeloma cells. T cells are white blood cells that can be utilised to fight against diseases.

When given standard therapy, almost all myeloma patients relapse frequently. There is an immediate need for additional therapeutics for patients who relapse or develop resistance to all authorised multiple myeloma drugs because of their poor prognosis. Even though it’s an early-stage experiment meant to gauge acceptability and establish a safe dosage, this study represents an essential step in fulfilling that requirement.

The phase 2 trial presented at ASH corroborated the effectiveness and safety findings in the phase 1 investigation. In the phase 2 experiment, 145 individuals received a higher biweekly dose whereas 143 patients received a weekly dose.

According to Dr. Chari, the combined response rate for these two groups was almost 73%. Except for patients with a rare form of multiple myeloma that also affects organs and soft tissues, the response rate was maintained across all categories investigated. Nearly 60% of patients in both groups had a “very good partial response” or better, and more than 30% had a complete response or better.
