A groundbreaking study presented at the 2024 ASH Annual Meeting has unveiled significant advancements in the treatment of relapsed/refractory non-Hodgkin lymphoma (NHL). The trial, which evaluated UF-Kure19, a rapidly manufactured CAR T-cell therapy, demonstrated remarkable efficacy and minimal toxicity. Of the ten patients treated, eight achieved complete responses (CR), while the remaining two experienced stable disease (SD). This innovative approach utilizes an ultra-fast manufacturing process that significantly reduces production time compared to traditional methods. The findings suggest that this novel therapy could revolutionize the treatment landscape for NHL patients by enhancing response rates and safety profiles.

The research was led by Dr. David Wald, a professor at Case Western Reserve University's School of Medicine. He highlighted that naive/early memory CAR T-cell–enriched products may enhance in vivo proliferation and improve the durability of responses. Among the participants, only 20% experienced cytokine release syndrome (CRS), and 10% encountered neurotoxicity, both of which resolved within a day. These results underscore the potential of UF-Kure19 to offer better safety outcomes.

The UF-Kure19 therapy leverages a streamlined manufacturing process that can produce CAR T-cells in less than one day. Traditional methods typically require 7 to 14 days, involving multiple steps such as apheresis, T-cell isolation, activation, gene transfer, and expansion. In contrast, UF-Kure19 bypasses the need for T-cell isolation and expansion, resulting in a highly efficient and cost-effective production method. Preclinical data revealed that UF-Kure19 cells exhibited over a 100-fold increase in proliferation compared to those produced using conventional workflows, demonstrating superior in vivo performance.

The phase 1 trial enrolled patients with various subtypes of NHL, including mantle cell lymphoma, follicular lymphoma, diffuse large B-cell lymphoma, and plasmablastic lymphoma. Participants underwent lymphodepleting chemotherapy before receiving the CAR T-cell infusion. The primary objective was to evaluate the safety and tolerability of UF-Kure19, while secondary objectives included assessing overall response rate, CR rate, and duration of response. Dr. Wald emphasized the need for further clinical testing to validate and expand upon these promising initial results.

This pioneering therapy holds great promise for improving treatment outcomes and patient safety in relapsed/refractory NHL. The rapid manufacturing process not only addresses key limitations of current CAR T-cell therapies but also paves the way for broader applications across hematologic and solid malignancies. The success of UF-Kure19 marks a significant step forward in the field of immune oncology, offering hope to many who face challenging diagnoses.
