Bispecifics, CAR-T cell therapy and the future of hematologic oncology
The American Society of Hematology (ASH) Annual Meeting has long served as a benchmark for advancements in blood cancer research and treatment, and this year was no exception. Taking place in Orlando, Florida, from December 6 through 9, ASH 2025 delivered groundbreaking data and lively discussions that reinforced the momentum we’re experiencing in hematologic oncology. Every conversation seemed to point to a new era in patient-centric research, treatment and care.
Three themes dominated the dialogue: bispecific antibodies, the evolution of CAR T-cell therapies, and fixed-duration treatment strategies. Each area represents a shift in how we approach effectiveness, access, and quality of life for people living with blood cancer. Key highlights include:
Bispecific antibodies: The next frontier in immuno-oncology
Bispecific antibodies have been steadily gaining traction, but ASH 2025 marked a turning point. These therapies, designed to engage two different targets simultaneously (often a tumor antigen and a T-cell receptor) are demonstrating value in real-world and clinical trial settings.
Bispecifics are remarkably versatile and no longer confined to just late-line therapy. Data presented at ASH showcased their potential in earlier lines of treatment for multiple myeloma and certain types of lymphoma. This shift could dramatically impact the treatment pathway and improve long-term outcomes.
Several presentations highlighted “off-the-shelf” bispecifics that eliminate the logistical challenges associated with personalized therapies. Unlike CAR T-cell products, which require complex manufacturing and time, bispecifics can be administered more quickly, making them a promising and practical option for patients with aggressive disease.
The safety profile continues to improve as well. Innovations in dosing strategies and step-up regimens are reducing cytokine release syndrome risk, making these therapies more tolerable. For clinicians and patients alike, this means fewer trade-offs between efficacy and safety which is a win for everyone.
CAR-T-cell therapy’s next chapter
CAR T-cell therapy continues to be a major focus at ASH, and this year’s data showed its growing role in hematology oncology care.
One key development centered on advancements in “off-the-shelf” CAR-T cell therapies—allogeneic therapies designed to overcome the time and cost challenges of autologous manufacturing. Advances in gene editing and immune evasion strategies are bringing us closer to a future where patients don’t have to wait weeks for their cells to be engineered.
Another important trend was earlier-line use. Several trials explored CAR T- therapy as a second-line option for aggressive lymphomas and relapsed myeloma, reporting strong response rates and durability. This could reshape treatment guidelines and offer new hope for patients with limited options.
Despite progress, challenges remain, particularly in manufacturing scalability, cost efficiency, and ensuring long-term safety. The future trajectory is clear: CAR T-cell therapy is evolving from a boutique intervention to a cornerstone of hematologic oncology.
Fixed-duration therapy: redefining treatment philosophy
Perhaps the most patient-centric trend at ASH 2025 was the growing embrace of fixed-duration therapy. Historically, many hematologic oncology treatments have been indefinite, requiring patients to remain on therapy until progression or intolerance. While effective, this approach often comes with cumulative toxicity, financial strain, and significant impact on quality of life.
Enter time-limited regimens. Data from pivotal trials like CLL17 and FLAIR demonstrated that fixed-duration combinations, such as venetoclax paired with BTK inhibitors and anti-CD20 antibodies, can deliver deep, durable remissions without continuous therapy.
This shift delivers real benefits across the board. Patients can achieve treatment-free intervals, improving quality of life and reducing long-term costs. Clinicians gain flexibility in treatment pathways while payers benefit from a more sustainable model for high-value care.
Adding to this trend is the growing use of MRD-guided strategies which personalizes treatment length based on measurable residual disease status. This precision approach ensures patients receive just the right amount of therapy; a perfect example of how scientific breakthroughs can truly improve lives.
Why these breakthroughs matter
For me, ASH 2025 was a clear reminder of why our work matters.
From the versatility of bispecific antibodies to the evolution of CAR T-cell therapies and the patient-first approach of fixed-duration treatment, the progress we are witnessing is nothing short of inspiring. These innovations aren’t just changing protocols; they’re changing lives by improving outcomes, access, and quality of care. And with MRD-guided strategies adding even more precision, the future looks brighter than ever. It’s exciting to be part of a field where science and compassion truly go hand in hand.
