KLN-1010 gene therapy for relapsed or refractory multiple myeloma

A Phase 1 Study to Evaluate the Safety of KLN-1010, a Novel, In Vivo Gene Therapy to Generate Anti-B Cell Maturation Antigen (Anti-BCMA) Chimeric Antigen Receptor-T Cells (CAR-T) in Patients With Relapsed and Refractory Multiple Myeloma

Phase 1 Interventional Kelonia Therapeutics, Inc. · NCT07075185

This Phase 1 trial will try KLN-1010, an in vivo CAR‑T gene therapy, to see if it is safe and can be given at a tolerable dose for people with relapsed or refractory multiple myeloma who have had at least three prior therapies.

What this trial studies

KLN-1010 is an in vivo CAR‑T gene therapy administered in a Phase 1 dose‑finding design to identify a recommended Phase 2 dose and to monitor safety and tolerability. The trial enrolls adults with measurable relapsed or refractory multiple myeloma who have received at least three prior lines of therapy, including a proteasome inhibitor, an IMiD, and a CD38‑directed antibody, and who have ECOG performance status 0–1 and acceptable laboratory values. Escalating doses of KLN-1010 will be given at academic sites to define dose‑limiting toxicities and dosing parameters. Secondary data on anti-myeloma activity and duration of response will be collected to inform further development.

Who should consider this trial

Good fit: Adults with relapsed or refractory multiple myeloma with measurable disease who have had at least three prior lines of therapy including a proteasome inhibitor, an IMiD, and an anti‑CD38 antibody, with ECOG 0–1 and acceptable laboratory tests, and no CNS involvement or active systemic infection.

Not a fit: Patients with plasma cell leukemia, Waldenström's macroglobulinemia, POEMS syndrome, primary light chain amyloidosis, known CNS myeloma, ongoing acute systemic infection, or those requiring systemic steroids are not eligible and therefore would not benefit from this trial.

Why it matters

Potential benefit: If successful, KLN-1010 could provide a new CAR‑T–style option that may control disease in heavily pretreated myeloma patients without the need for individualized cell collection.

How similar studies have performed: Autologous BCMA‑directed CAR‑T therapies have shown high response rates in relapsed myeloma, but in vivo gene‑delivery CAR‑T approaches like KLN-1010 are novel and have limited human data to date.
