Fresh Versus Cryopreserved LV20.19 CAR T-Cell Therapy for Relapsed, Refractory DLBCL and Follicular Lymphoma (TCT-ASTCT-CIBMTR 2024)
Cryopreservation of LV20.19 CAR T-cell therapy had no meaningful impact on ORR, DOR, toxicity profile, time to CRS, or in-vivo expansion. Although fresh products facilitate shorter time from apheresis to infusion, cryopreservation may allow for rapid advancement of products to multicenter trials and licensure.

Phase 1 Trial of LV20.19 CAR T-Cells for Relapsed, Refractory CLL and Richter's Transformation (TCT-ASTCT-CIBMTR 2024)
12 pts (86%) had disease progression on covalent BTKi and venetoclax...In terms of safety, 100% (n=14) developed CRS and 93% (n=13) required tocilizumab...Six (66%) IEC-HS pts required anakinra for management... While LV20.19 CAR T cells were efficacious in CLL and RT it was limited by high rates of IEC-HS especially among CLL pts, a phenomena not commonly seen with other histologies. With two DLTs in the CLL cohort, the dose for future CLL pts was reduced to 1x10e6 cells/kg. Additional studies are needed to understand how CLL biology drives CAR IEC-HS.

Adaptive Manufacturing of LV20.19 CAR T-Cells for Relapsed, Refractory Mantle Cell Lymphoma (ASH 2023)
Fludarabine/cyclophosphamide lymphodepletion was started during MF to facilitate fresh infusion in eligible pts...Both received only a single dose of intrathecal hydrocortisone (no systemic steroids) with resolution of neurotoxicity within 24 hours of administration... Bispecific LV20.19 CAR T-cells with adaptive MF process is feasible, safe, and efficacious for R/R MCL with ORR 100%, no Grade 3+ CRS and low rates of Grade 3+ ICANS (12%). Adaptive MF enriched the final product with higher percentages of T-SCM/T-CM CAR cells and allowed most pts to receive CAR-T cells within 8 days of apheresis. Dual targeting of CD20 and CD19 with CAR-T cells may improve outcomes in pts with relapsed, refractory MCL.

RESULTS FROM A PHASE 1/2 STUDY OF TANDEM, BISPECIFIC ANTI-CD20/ANTI-CD19 (LV20.19) CAR T-CELLS FOR MANTLE CELL LYMPHOMA (EHA 2023)
After safety run-in, we opened a 14-patient single stage Phase II MCL arm with flexible 8/12-day manufacturing (MF) and goal of fresh infusion with a target complete response (CR) rate of 50% to exceed the historical CR rate of Ibrutinib in R/R MCL of 20%...Eleven of 14 pts (79%) progressed on a Bruton's Tyrosine Kinase inhibitor (BTKi) and 5 (36%) of these pts also progressed on a non-covalent BTKi (pirtobrutinib) administered on a clinical trial...Bispecific LV20.19 CAR T-cells expanded with IL7/IL15 and manufactured onsite are safe and efficacious for R/R MCL with a day 90 ORR of 100%, and only one relapse to date with a median follow-up of nearly 2-years. Toxicity profile was encouraging with no Grade 3+ CRS and low rates of Grade 3+ ICANS. Dual targeting of CD19 and CD20 with CAR-T cells may improve outcomes in pts with R/R MCL.

Bispecific Anti-CD20/Anti-CD19 (LV20.19) CAR T-Cells for Richter’s Transformation (TCT-ASTCT-CIBMTR 2023)
At time of RT diagnosis, all patients received R-CHOP chemotherapy as frontline management. Bispecific LV20.19 CAR T-cell therapy resulted in robust early and durable responses in patients with heavily pre-treated CLL and RT. To date, there is limited data on outcomes for RT with CAR T-cell therapy. Given historical outcomes, bispecific LV20.19 CAR T cells offer a promising strategy for R/R RT.

Nine of 11 pts had progressed on a Bruton’s Tyrosine Kinase inhibitor (BTKi) and 4 of these pts had also progressed on a non-covalent BTKi (pirtobrutinib) administered on a clinical trial (Table 1). Bispecific LV20.19 CAR T-cells expanded with IL7/IL15 are safe and efficacious for R/R MCL with an ORR of 100%, no relapses with a median follow-up of >1.5 years, no Grade 3+ CRS, and low rates of Grade 3+ ICANS (9%). All pts on the Phase II arm had CAR T-cells manufactured on-site in 8 days with fresh CAR T-cell infusion and lymphodepletion starting during MF. Dual targeting of CD19 and CD20 with CAR-T cells may improve outcomes in pts with R/R MCL.

Single Cell Cytokine Analyses of Bispecific, Tandem, Anti-CD20, Anti-CD19 CAR T-Cells from Patients with Relapsed, Refractory B-Cell Malignancies (ASH 2022)
There were 15 patients in the IL-2 trial and 22 patients in the IL-7+15 trial with adequate LV20.19 CAR T-cells for analysis. For cells expanded in IL-7+15 vs IL-2, the global PFA was 53.14% vs 40.12%, p=0.01, CD8 PFA was 51.15% vs 41.24% p=0.01, while the CD4 PFA was 55.05% vs 46.23%, p=0.08, (Figure 1A). Similarly, the global PSI was 1508 vs 956 p=0.0003, CD8 PSI was 1333 vs 865 p=0.0009, and CD4 PSI was 1580 vs 865, p<0.0001.

Long-term outcomes and predictors of early response, late relapse and survival for patients treated with bispecific LV20.19 CAR T-cells. (PubMed, Am J Hematol)
Bridging therapy and higher absolute lymphocyte count on day of CAR-T infusion were associated with inferior survival outcomes. In conclusion, this initial trial of LV20.19 CAR-T demonstrates a signal for favorable long-term outcomes for patients with R/R B-cell malignancies.

8-Day Versus 12-Day Manufactured LV20.19 CAR T-Cells for B-Cell Non-Hodgkin Lymphoma (ASH 2022)
Bispecific LV20.19 CAR T-cells are safe and efficacious for pts with R/R B-cell NHL. Shorter MF produced a more naïve CAR T-cell product with no difference in toxicity profile. Higher percentage of CM T-cells and lower EMRA T-cells were observed earlier in the MF process both between the two cohorts and intra-patient.

MRD Status By Clonoseq ® Is a Poor Predictor of Long-Term Outcomes after Bispecific LV20.19 CAR T-Cell Therapy for Relapsed, Refractory B-Cell NHL (ASH 2022)
Relapse after CAR T-cell therapy remains a significant clinical challenge. New predictors are indicated to determine which responding patients after CAR-T cell therapy are more likely to relapse. Utilizing the commercially available Adaptive clonoSEQ® assay, early MRD assessment was not predictive of long-term clinical outcomes in DLBCL and FL.

Associations between Socioeconomic Status and Bispecific LV20.19 CAR T-Cell Therapy Outcomes (ASH 2021)
Earlier CRS onset and increased pain were also seen in low SES patients, with qualitatively higher incidences of CRS, neurotoxicity, and poor sleep. Future work will focus on acquiring a larger sample to further delineate the impact of SES on cancer outcome disparities among CAR T-cell recipients, including but not limited to PROs, neurotoxicity, and survival.

Manufacturing Bispecific LV20.19 CAR T-Cells with IL-7 & IL-15 for a Shorter Duration Improves CAR T-Cell Immunophenotype While Maintaining Target Cell Dose (ASH 2021)
Given the composition of CAR-T products has been shown to impact anti-tumor efficacy, this suggests that manufacturing bispecific CAR T-cells in IL7+15 for a shorter duration could lead to greater clinical efficacy without negatively impacting attainment of cell dose. Clinical outcomes of 8- vs 12-day manufactured IL-7+15 expanded LV20.19 CAR T-cells will be reported separately.

Bispecific LV20.19 CAR T-Cells Expanded in IL-7 and IL-15 Have Greater Polyfunctionality and Polyfunctional Strength Than CAR T-Cells Expanded in IL-2 (ASH 2021)
Expansion of LV20.19 CAR T-cells in IL7+15 may generate a more robust CAR-T product than expansion in IL-2, which could improve persistence, cytotoxicity, and ultimately patient outcomes. An ongoing prospective trial (NCT04186520) is evaluating clinical outcomes with IL-7+15 expanded LV20.19 CAR T-cells and is reported separately.
