Kelonia Therapeutics to Present Preclinical Data Highlighting Therapeutic Potential of in vivo CAR-T Cell Therapy in Multiple Myeloma

Preclinical data supports potential for iGPS® particles to provide off-the-shelf in vivo CAR-T Cell therapies without need for lymphodepleting chemotherapy –

BOSTON, Mass., April 2, 2024Kelonia Therapeutics, a biotech company revolutionizing in vivo gene delivery, today announced new preclinical data from its lead program KLN-1010, which will be presented at the American Association for Cancer Research (AACR) Annual Meeting 2024 in San Diego, California. KLN-1010, a novel, in vivo CAR-T cell therapy candidate for the treatment of multiple myeloma, which leverages the company’s in vivo Gene Placement System (iGPS®) technology, demonstrated that it is safe and effective in preclinical animal models.

“These data reinforce the best-in-class potential of our in vivo CAR-T cell therapies,” said Kevin Friedman, Ph.D., Chief Executive Officer and Founder of Kelonia. “By eliminating the need for ex vivo manufacturing and toxic lymphodepleting chemotherapy, we belive our iGPS technology will remove barriers that currently prevent patients from accessing transformative genetic medicines. We are excited by the preclinical profile of KLN-1010, and are looking forward to advancing this program towards the clinic in the near future.”

Diverse T cell lineages, including memory and effector CD4 and CD8 T cells were modified in vivo by KLN-1010 to express a fully human anti-BCMA CAR, without detectable transduction of multiple myeloma tumor cells. A single intravenous injection of KLN-1010 displayed potent anti-tumor efficacy and caused complete tumor regression at multiple dose levels in several preclinical animal models. In other studies, treatment of non-human primates with an iGPS particle expressing an anti-CD20 CAR resulted in potent CAR-T cell activity lasting several months without the need for additional treatments or conditioning chemotherapy.

Details for the poster presentation are as follows:
