Treatment Guidelines for PTCL: SFll CHOP Based
NCCN. Clinical practice guidelines in oncology: non-Hodgkin’s lymphoma. v.1.2013.
First-‐line Therapy
Clinical trial (preferred) ALCL, ALK+ histology • CHOP-‐21 • CHOEP-‐21
Other histologies (ALCL, ALK-‐; PTCL-‐NOS; AITL; EATL), regimens that can be used include: • CHOEP • CHOP-‐14 • CHOP-‐21 • CHOP followed by ICE • CHOP followed by IVE, alternaNng with intermediate-‐dose methotrexate (Newcastle regimen)
• Dose-‐adjusted EPOCH • HyperCVAD, alternaNng with high-‐dose methotrexate and cytarabine
First-‐line ConsolidaNon
All paNents except low risk (aaIPI) should be considered for high-‐dose therapy and stem cell rescue; ALCL, ALK+ is a subtype with good prognosis and does not need consolidaNve transplant if in remission

German High-‐Grade Lymphoma Study Group: T-‐Cell Lymphoma Cohort Analysis
• 320 paNents with mature nodal or extranodal T-‐cell or NK-‐cell lymphoma treated on 7 phase II or III studies (1993-‐2007)
• ALK posiNve: 78 paNents (24.4%) • ALK negaNve: 113 paNents (35.3%) • Treated with CHOP ± etoposide: 100%

PTCL (≥ 1% CD30 expression in malignant cells) • Two strategies for incorporaNng BV into treatment were examined:
• SequenUal treatment, in which sALCL paNents received 2 cycles of 1.8 mg/kg BV followed by 6 cycles standard-‐dose CHOP
• CombinaUon treatment, in which paNents with PTCL, including those with sALCL, received 6 cycles of BV in combinaNon with CHP (VincrisNn was omiled to eliminate the potenNal for addiNonal neurotoxicity).

Conclusions • There is a clear unmet clinical need for PTCL paNents
• Disease biology and classificaNon have to be improved • Long-‐term survival is poor (20 -‐25% with anthracyclin-‐based treatment)
• Current treatment guidelines are sNll CHOP-‐based
• Up-‐front autologous transplantaNon has improved PFS in responding paNents
• Ongoing studies invesNgate combinaNons with romidepsin and CHOP/CHOEP, or BV or Pralatrexate
![Page 21: Novel treatment strategies in peripheral T-cell lymphomas · Novel treatment strategies in peripheral T-cell lymphomas Prof. Paolo Corradini Dept. of Hematology and Bone Marrow Transplantation](https://reader034.fdocuments.in/reader034/viewer/2022042310/5ed760d52d26a13e8d6e988c/html5/thumbnails/21.jpg)
New agents in relapsed/refractory PTCL
• The historical outcomes for paNents with relapsed disease have been especially dismal
• In a recent retrospecNve study on 153 paNents with relapsed or refractory PTCLs who did not undergo transplant , the reported median OS was only 5.5 months and the PFS 3.1 months (1)
• These data do not capture possible gains from novel agents, since paNents included in the study had been diagnosed prior to 2010, before the approval of the new drugs.

Results From a Pivotal, Open-‐Label, Phase II Study of Romidepsin in Relapsed or Refractory Peripheral T-‐Cell Lymphoma Aner Prior Systemic Therapy
• 130 paNents with histologically confirmed R/R PTCL received ROMIDEPSIN at 14 mg/m2 as IV infusion on days 1, 8, and 15 every 28 days, for up to 6 cycles
• ORR 25% • CR/CRu 15% • Median DoR 17 months • The most common grade 3 adverse events were thrombocytopenia (24%), neutropenia (20%), and infecNons (all types, 19%). Coiffier B et al, J Clin Oncol 2012 Feb 20;30(6):631-‐6.

The BENTLY Trial • 60 paNents with histologically confirmed peripheral T-‐cell lymphoma or cutaneous T-‐cell lymphoma ,who progressed amer one or more lines of prior chemotherapy, received BENDAMUSTINE at 120 mg/m2 per day on days 1 -‐ 2 every 3 weeks for six cycles.
• In the intent-‐to-‐treat populaNon: • ORR 50% • CR 28% • DoR 3.5 months • PFS 3.6 months; OS 6.2 months
• The most frequent grade 3 to 4 adverse events were neutropenia (30%), thrombocytopenia (24%), and infecNons (20%).

ObjecUve responses in relapsed T-‐cell lymphomas with single-‐agent brentuximab
This phase 2, open-‐label, mulNcenter study was iniNated to evaluate the efficacy and safety of single-‐agent BV in R/R T cell lymphomas • Brentuximab vedoNn 1.8 mg/kg was administered every 3 weeks unNl progression or unacceptable toxicity.
Inclusion criteria: • Histologically confirmed mature T-‐cell lymphoma with any detectable CD30 expression per insNtuNonal laboratory using IHC
• PaNents who have had at least one prior systemic therapy

• 64% of ORR in the 14 paNents with ≤ 15% CD30 expression by central review.
