Review, Journal, CAR T-Cell Therapy: Sequencing bispecific antibodies and CAR T cells for FL. (Pubmed Central) - Dec 7, 2024 We generally prioritize CAR T before BsAbs for patients with proven or suspected HT given the curative-potential of this approach based on trial data from R/R diffuse large B-cell lymphoma; it is unknown whether BsAbs offer the same long-term benefit in transformed FL. Overall, with the ability to personalize the sequencing of BsAbs and CAR T, the recently expanding portfolio of highly effective immunotherapies for R/R FL is poised to offer considerable benefit to this patient population.

Impact of Absolute Lymphocyte Count on Efficacy and Toxicity of T-Cell Engagers in Non-Hodgkin's Lymphoma () - Dec 7, 2024 - Abstract #ASH2024ASH_9768; This differs from the information currently known about ALC and CAR-T therapy and should be confirmed with a larger patient population. If confirmed in larger, multi-institution or in head-to-head studies, this could shift the treatment paradigm in favor of TCEs over CAR-T in patients with low ALC.
- |||||||||| Estimation of Eligibility and Response to Bispecific Antibody Therapy in US Patients with Lymphoma and Multiple Myeloma () - Dec 7, 2024 - Abstract #ASH2024ASH_9653;
Excluding blinatumomab, all have gained accelerated approval through phase II trials to treat relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL); primarily diffuse large B-cell lymphoma (DLBCL and follicular lymphoma (FL), and R/R multiple myeloma (MM)...The calculated number of people eligible was multiplied by the overall response rate (ORR) reported in the trial that led to the bsAb approval for each year a therapy had an approval, using the highest calculated response, to estimate the population who would potentially benefit of these therapies.ResultsSix bsAbs were approved in the US since 2022 to treat NLH and MM : epcoritamab and glofitamab in 2023 to treat R/R DLBCL and other mature B-cell neoplasms, mosunetuzumab in 2022 and epcoritamab in 2024 to treat R/R grade 1-3A FL, and for MM, teclistamab in 2022, and elranatamab and talquetamab in 2023...Based on best available response rates from registration trials, we estimated that 9.6% and 10.5% newly diagnosed NHL and MM patients, respectively, would potentially benefit from bsAbs.ConclusionsEven though CR and ORR of bsAbs are high for highly pretreated patients, we found the percentage of newly diagnosed NHL and MM patients who would become potentially eligible and would respond to these therapies to be quite low (approximately only 1 out of 10). Even though these conclusions are driven by best-case scenario assumptions and have a risk of bias, they provide insights of the actual impact and reach of these newer therapies.

Efficacy and Safety Outcomes of CAR T-Cell Therapies in Patients with Relapsed/Refractory B-Cell Non-Hodgkin Lymphoma Who Received Prior Treatment with Mosunetuzumab () - Dec 7, 2024 - Abstract #ASH2024ASH_8598; P1/2 Two (18.2%) patients received bendamustine within 12 months prior to administration of CAR T-cell therapy...The CAR T-cell therapies received were an investigational CD19-targeted CAR T-cell therapy (n=4), axicabtagene ciloleucel (n=3), brexucabtagene autoleucel (n=2), and tisagenlecleucel (n=2).As of July 12, 2024, in patients with indolent B-NHL, the BOR rate with CAR T-cell therapy was 100% (6/6), with 3 (50.0%) patients achieving a CR; duration of response (DOR) ranged from 3.4 to 59.3 months, with 4 responses ongoing...These results suggest that CAR T-cell therapy is a good treatment option post mosunetuzumab for patients with R/R B-NHL; however, larger studies are needed to fully characterize the efficacy and safety of CAR T-cell therapy after mosunetuzumab. Additional patient data, including from other institutions, will be presented.
- |||||||||| Cytokine Release Syndrome: Trends with T Cell Engaging Bispecifics from a Systematic Review of Licensing Applications () - Dec 7, 2024 - Abstract #ASH2024ASH_7878;
Mosunetuzumab and elranatamab had the lowest CRS risk among TCEs for non-hodgkin's lymphoma (NHL) (range 39-70%) and multiple myeloma (MM) (range 58-79%), respectively...All TCEs employed a 2 step priming approach, except blinatumomab (1 step; continuous infusion) and talquetamab bi-weekly (3 step), and were successful at mitigating CRS beyond the first full dose...Covariates associated with CRS included baseline factors (disease status, treatment history, target level, effector cell status, age) and on-treatment factors (tocilizumab use, prior Cmax)...Thus, further characterizing CRS and establishing a link between drug levels, biomarkers, and clinical events will not only aid TCE development but also benefit patients by reducing the need for intensive clinical interventions and hospitalization. Quantitative clinical pharmacology methods including mechanism- and empirical-based approaches will continue to be instrumental in TCE development, especially as regimens become more complex with combination and pretreatment integration.

These features of EVOLVE205 appear to offer efficacy and safety advantages compared to clinically available CD20-targeted TCE therapies and BCDTs for the treatment of B cell lymphomas and for B cell-mediated autoimmune diseases.
