Aggressive lymphomas - New agents
POSTER

Conclusion: In the ongoing TRANSCEND NHL 001 study, liso-cel continues to demonstrate the ability to be safely delivered to patients with R/R B-cell NHL, including those with secondary CNS lymphoma, a population of patients with a highly unmet medical need. No excess NE was noted in this population. This cohort continues to be evaluated.

Conclusion: Among all pts with r/r DLBCL only 24% presented clinical and disease characteristics suitable for CARTs treatment. Moreover, some eligible pts run the risk to become ineligible because of poor disease control. The 4 week period to obtain CART-cells is a major obstacle to successful treatment. CART-cell treatment needs to be planned earlier in the disease course to optimize the outcome. The feasibility in Italy over the last 6 months of CART cells treatment has been largely unsatisfactory and primarily limited by the lack of commercial products. Our observational study is ongoing.

Conclusion: Step-fractionation has enabled continued dose escalation of mosunetuzumab with no apparent increases in toxicity, exhibiting a promising risk-benefit profile.

Conclusion: The combination of acalabrutinib plus pembrolizumab was well tolerated, with meaningful activity and some exceptional responders (>24 months) in these patients with relapsed/refractory diffuse large B-cell lymphoma. Randomized trials of the combination versus single agent are needed.

Conclusion: 5F9+rituximab is a novel immunotherapy blocking a key macrophage/cancer checkpoint. It is well tolerated with rapid and durable responses observed in both heavily pre-treated DLBCL and indolent lymphoma patients. Ph2 enrollment is ongoing (NCT02953509). Funded by Forty Seven and the Leukemia and Lymphoma Society.

Conclusion: REGN1979 was well tolerated in pts with R/R B-NHL. No DLTs and no significant neurological toxicity were observed. Treatment with REGN1979 showed impressive efficacy with a 100% ORR in R/R FL starting at doses above 5mg. With increasing doses, more resistant tumors such as R/R DLBCL are showing benefit, approaching the ORR seen with R/R FL at 80 mg. Based on these efficacy findings, a phase 2 study testing a selected dose in R/R FL Gr 1-3a, R/R DLBCL, and other R/R B-NHL subtypes is planned.

Conclusion: Preliminary activity of tipifarnib was observed in PTCL pts, particularly in those with tumors of AITL histology and high CXCL12 expression and enrollment in the CXCL12+ cohort continues.

Conclusion: Sintilimab is effective and well tolerated in r/r ENKTL and could be a promising treatment option for these patients. Early disease progression observed by PET scan in this study could be pseudo-progression as it did not correlate with poor outcome, which warrants further investigation. NCT03228836
