Hodgkin Lymphoma and T/NK Cell Lymphoma—Clinical Studies: Immunotherapy and Targeted Strategies

679  A Phase I Study with an Expansion Cohort of the Combinations of Ipilimumab, Nivolumab and Brentuximab Vedotin in Patients with Relapsed/Refractory Hodgkin Lymphoma: A Trial of the ECOG-ACRIN Research Group (E4412: Arms G-I)

Catherine Diefenbach, et al.

The Abstract concludes: In this study of the triplet combination of BV, Ipi and Nivo for R/R HL, therapy was generally well tolerated, although more grade 3 AEs were seen than in the doublets. In a heavily pretreated patient population, with 9 patients post SCT, the ORR of 95% and CR rate of 79% in evaluable patients is extremely promising. Data will be updated to include longer term PFS and OS by the time of the meeting. Optimization of this strategy is ongoing in E4412, now a randomized phase 2 study comparing the doublet of BV-Nivo to the triplet of BV-Ipi-Nivo.


680  CD30-Chimeric Antigen Receptor (CAR) T Cells for Therapy of Hodgkin Lymphoma (HL)

Carlos A. Ramos, et al.

The Abstract concludes: Our data indicate that infusion of T cells carrying a CD30.CAR containing a CD28 endodomain after lymphodepleting chemotherapy is safe, with limited toxicities at the dose levels tested. CD30.CAR expansion is improved with inclusion of pre-infusion standard lymphodepleting chemotherapy and appears to be associated with improved efficacy in relapsed patients (6/8 CR versus 1/6 CR, P= 0.03).


681  Clinical Responses to CAR.CD30-T Cells in Patients with CD30+ Lymphomas Relapsed after Multiple Treatments Including Brentuximab Vedotin

Natalie S Grover, et al.

The Abstract concludes: We show that CD30.CAR-Ts combined with lymphodepletion with benda/ flu are safe and at 2 x 108 CAR T cells/m2 demonstrate excellent antitumor activity for pts with r/r CD30+ lymphomas. We also find that the addition of flu is critical for enhancing cytokines important for T cell growth and persistence. Finally, we demonstrate a significant PFS advantage in pts with r/r CD30+ lymphoma who received the highest dose level combined with benda and flu.


682  Tislelizumab (BGB-A317) for Relapsed/Refractory Classical Hodgkin Lymphoma: Preliminary Efficacy and Safety Results from a Phase 2 Study

Yuqin Song, et al.

The Abstract concludes: In this study, tislelizumab therapy was shown to be highly active resulting in a high CR rate in patients with R/R cHL who had failed or were ineligible for ASCT. Tislelizumab was generally well-tolerated in Chinese patients with R/R cHL. The safety profile was generally consistent with that of other PD-1 inhibitors for the treatment of cHL.


683  The Combination of Duvelisib, a PI3K-δ,γInhibitor, and Romidepsin Is Highly Active in Relapsed/Refractory Peripheral T-Cell Lymphoma with Low Rates of Transaminitis: Results of Parallel Multicenter, Phase 1 Combination Studies with Expansion Cohorts

Steven M. Horwitz, et al.

The Abstract concludes: Duvelisib in combination with romidepsin is highly active in pts with PTCL with tolerable side effects. Duvelisib can be safely combined with romidepsin at a 3-fold higher dose than with bortezomib (75 mg BID vs 25 mg BID) with much lower rate of Gr 3-4 transaminitis than single-agent duvelisib at the same dose. The high response rates and safety of Arm A (Duvelisib + Romidepsin) in PTCL appears to be a potential therapeutic advance and warrants further evaluation in a larger study.


684  IPH4102; An Anti-KIR3DL2 Monoclonal Antibody in Refractory Sezary Syndrome: Results from a Multicenter Phase 1 Trial

Martine Bagot, et al.

The Abstract concludes: IPH4102 is highly effective in patients with refractory SS. It induces meaningful clinical activity and improves quality of life placing it as an encouraging treatment option for these patients. Further development in SS and other T-cell malignancies is underway.
