Background Chimeric antigen receptor T cell (CAR-T) therapy has emerged as a transformative treatment modality for selected subtypes of non-Hodgkin lymphoma (NHL). While multiple CAR-T products have demonstrated remarkable clinical activity, the overall clinical development landscape remains heterogeneous, with substantial variation in trial design, target selection, geographic distribution, and endpoint prioritization. A comprehensive analysis of the global clinical trial landscape is essential to contextualize current progress and identify unmet needs in this rapidly evolving field. Methods We conducted a systematic landscape analysis of CAR-T–related clinical trials for NHL using the Trialtrove database. Interventional trials registered up to December 18, 2025, were retrieved using predefined search criteria. Eligible studies were screened according to standardized inclusion and exclusion criteria. Key trial characteristics, including trial status, phase, geographic location, sponsor type, molecular targets, and reported clinical endpoints, were extracted and analyzed descriptively. Results A total of 360 eligible clinical trials were included in the final analysis. The global CAR-T clinical trial landscape in NHL is characterized by rapid expansion and a predominant focus on early-phase development. Trial activity is highly concentrated in a limited number of countries, with academic institutions serving as the primary drivers of clinical investigation. CD19-directed CAR-T therapies dominate the current landscape, although emerging diversification toward alternative targets is evident. Reported study endpoints largely emphasize safety and short-term efficacy, whereas durable clinical outcomes remain less frequently assessed, reflecting the exploratory nature of most trials. Conclusion CAR-T therapy development in NHL continues to advance rapidly, driven by academic innovation and expanding preclinical insights. However, persistent challenges related to antigen escape, treatment durability, and trial design remain. Future progress will require the integration of next-generation CAR engineering strategies, broader incorporation of long-term clinical endpoints, and alignment with evolving regulatory and policy frameworks to support sustainable clinical translation.
