INT2104 is a novel in vivo chimeric antigen receptor (CAR) gene therapy designed to generate CAR-T and CAR-NK cells in the patient’s body to target CD20-expressing malignant B cells

Interim safety and proof-of-concept data to be presented at a scientific meeting in 1H 2025

Interius BioTherapeutics, a clinical-stage company engineering targeted, programmable vectors for the precision delivery of genetic medicines, today announced that the first study participant has been dosed in INVISE, its first-in-human Phase 1 clinical trial of INT2104, a first-in-class gene therapy that delivers a CAR transgene to generate effector CAR-T and CAR-NK cells in vivo for the targeting of CD20-positive B cells for the treatment of B-cell malignancies.

“Interius was founded with a sense of urgency to provide patients with a new therapeutic option that does not require preconditioning or long manufacturing and wait times. Interius’s breakthrough technology allows precise targeting of gene therapies to specific cells via intravenous administration," said Interius President and CEO, Phil Johnson, M.D. "This milestone marks the first time that a durable in vivo CAR therapy has been used in the clinic. INT2104 has the potential to overcome ex vivo CAR therapy challenges with a single-dose, off-the-shelf, widely accessible therapy for the treatment of B cell malignancies enabled by Interius’s programmable platform. In our preclinical studies, we achieved successful B cell depletion in small and large animal models without chemotherapy and observed no signs of cytokine release syndrome (CRS) or neurotoxicity. We look forward to sharing interim clinical safety and proof-of-concept data at a scientific meeting next year.”

Dr. Michael Dickinson, MBBS, FRACP, Lead of the Aggressive Lymphoma Disease Group at Peter MacCallum Cancer Centre and Royal Melbourne Hospital and INVISE Principal Investigator, added, “The need for new, accessible treatment options for patients with cancer is critical. Innovative approaches, like in vivo CAR gene therapies, have the potential to transform how we treat cancer, offering faster, single-dose solutions that are less burdensome on patients and treatment centres.”
