Anti-apoptotic BCL2 was upregulated in all tumor cells from nonresponsive lesions, especially in CD30- subsets. We further confirmed a potent synergy between BV and BCL2 inhibitors in tumor cell lines, indicating a promising strategy to overcome resistance in CTCL.

In vivo, CD25-ApDC achieved complete tumor remission in xenograft and disseminated models with optimized dosing, showing efficacy and tolerability comparable to Brentuximab vedotin. Increasing drug-to-aptamer ratios further enhanced outcomes, supporting flexible dosing strategies. These findings highlight CD25-ApDC as a promising therapeutic modality for hematologic malignancies, offering advantages in specificity, tissue penetration, and manufacturability over conventional antibody-based therapies.

Nonetheless, some patients experienced high-grade AEs or symptom recurrence and stopped BV/PV therapy. Future studies may provide clarification and guide clinical practice.

The CD30 antibody-drug conjugate, brentuximab vedotin, and PD-1 inhibitors, nivolumab and pembrolizumab have transformed the care of patients with Hodgkin lymphoma and have been incorporated into earlier lines of therapy. Novel immunotherapies for patients with relapsed/refractory Hodgkin lymphoma include CAR-T products, EBV-specific T cells, bispecific antibodies, and checkpoint inhibitor combinations. We review the rationale for each and summarize safety, efficacy, and progress in clinical development.

The 36-month PFS (from first scan) was 73.0% (54.5, 85.0) for BV/Ipi/Nivo compared to 45.8% (26.3, 63.4) for BV/Nivo (HR=0.45, CI 0.19-1.08, one-sided p=0.03). The study did not meet its primary endpoint of superior CR rate for the triplet, but it supports the use of checkpoint-ADC induction prior to auto SCT, and there is an intriguing signal of disease control for patients wishing to defer or avoid SCT for the triplet of BV/Ipi/Nivo.

CHOP or CHOP-like regimens have long been the standard frontline therapy; however, the addition of brentuximab vedotin has improved overall survival and established a new standard of care for CD30-positive PTCL...Epigenetic modulators, including histone deacetylase inhibitors and an EZH1/2 inhibitor, have demonstrated particularly high activity in TFH-derived subtypes, supporting the integration of biomarker-driven patient selection as a path toward precision medicine in PTCL. This review summarizes current insights into the genetic landscape, recent clinical advances in novel agents, and future perspectives on therapeutic stratification, highlighting the need to translate molecular insights into durable clinical benefits for patients with PTCL.
