On November 24, 2025 Kelonia Therapeutics, Inc., a clinical-stage biotechnology company pioneering in vivo gene delivery, reported that its first results from the ongoing inMMyCAR study, a Phase 1 clinical trial evaluating KLN-1010, a novel in vivo gene therapy that generates anti-BCMA CAR-T cells in patients with relapsed and refractory multiple myeloma, will be presented in a late-breaking oral presentation at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2025 Annual Meeting in Orlando, Florida.

The late-breaking abstract features results from the first three patients treated with KLN-1010. All patients achieved minimal residual disease (MRD) negativity at month 1 that persisted through three months in the patient with the longest follow up. CAR-T cell expansion and persistence of memory CAR-T cells occurred without the use of lymphodepleting chemotherapy, apheresis, or ex vivo cell manufacturing.
"KLN-1010 is beginning to show the extraordinary clinical outcomes that may be possible with in vivo CAR-T therapy — early, deep responses from a single infusion without the barriers that limit access to traditional CAR-T treatments," said Kevin Friedman, Ph.D., Chief Executive Officer and Founder of Kelonia. "These initial data point to a potentially powerful medicine while also providing clear clinical validation of our iGPS platform; enabling a growing number of partnered programs as well as our wholly owned pipeline that includes KLN-1010. We are encouraged by these first-in-human results and looking forward to sharing additional details from the study with the scientific and medical communities at the ASH (Free ASH Whitepaper) Annual Meeting."
"In these early patients, we are seeing both rapid MRD-negative responses and persistent memory-phenotype CAR-T cells, a combination that has been strongly prognostic for durable clinical benefit with existing CAR-T approaches," said Simon Harrison, MBBS, MRCP(UK), FRCPath(UK), FRACP, Ph.D., Director of the Centre of Excellence in Cellular Immunotherapy at the Peter MacCallum Cancer Centre and lead author of the late-breaking abstract. "Achieving these outcomes without lymphodepleting chemotherapy or CAR-T cell manufacturing underscores the potential of this in vivo approach to fundamentally expand access to CAR-T therapy for patients with relapsed and refractory multiple myeloma."

About inMMyCAR
inMMyCAR is a Phase 1, open-label, dose-escalation clinical trial designed to assess the safety, tolerability, pharmacology and preliminary efficacy of a single dose of KLN-1010 in up to 40 patients. The primary endpoints are incidence and severity of treatment-emergent adverse events (TEAEs), including dose limiting toxicities (DLTs), and to establish the recommended Phase 2 dose of KLN-1010. KLN-1010 has been granted Human Research Ethics Committee (HREC) approval and Clinical Trial Notification (CTN) clearance by the Australian Therapeutic Goods Administration (TGA). This Phase 1 clinical trial marks the first time KLN‑1010 will be evaluated in humans. Additional information and study site information may be found on clinicaltrials.gov (NCT07075185).
About Relapsed and Refractory Multiple Myeloma
Multiple myeloma is a hematologic malignancy characterized by the proliferation of plasma cells in the bone marrow, leading to bone destruction, anemia, renal dysfunction, and immunosuppression. It is driven by complex genetic and epigenetic alterations that promote malignant cell survival and resistance to apoptosis. Relapsed and refractory multiple myeloma is characterized by clonal evolution, drug resistance, and increased disease heterogeneity, heightening the need for accessible, personalized therapeutic strategies.
About KLN-1010
KLN‑1010 is an investigational in vivo gene therapy that generates anti-BCMA CAR-T cells, targeting a protein expressed on the surface of multiple myeloma cells. Unlike traditional CAR‑T treatments, KLN‑1010 is administered to patients via direct transfusion and is designed to generate durable CAR‑T cells inside the body after a single dose, potentially eliminating the need for long wait times to receive treatment. This may overcome several limitations faced by current CAR-T approaches, including limited access to treatment and preconditioning chemotherapy.
