SWOG S1826, a randomized study of nivolumab(N)-AVD versus brentuximab vedotin(BV)-AVD in advanced stage (AS) classic Hodgkin lymphoma (HL).
Notice bibliographique
Résumé
LBA4 Background: The addition of BV to initial chemotherapy improves overall survival (OS) in adults and PFS in pediatric patients (pts) with AS HL. However, frontline BV adds toxicity, most pediatric pts receive radiation therapy (RT), and 7-20% of pts still develop relapsed/refractory (RR) HL. The PD-1 pathway is central to the pathogenesis of HL and PD-1 blockade is effective in RR HL. The adult and pediatric cooperative groups of the National Clinical Trials Network (NCTN) conducted the randomized, phase 3 S1826 trial to evaluate N-AVD vs BV-AVD in pts with newly diagnosed AS HL. Methods: Eligible pts were ≥12 years (y) with stage 3-4 HL. Pts were randomized 1:1 to either 6 cycles of N-AVD or BV-AVD. Recipients of BV-AVD were required to receive G-CSF neutropenia prophylaxis vs optional with N-AVD. Pre-specified pts could receive RT to residually metabolically active lesions on end of treatment PET. Pts were stratified by age, international prognostic score (IPS), and intent to use RT. Response and disease progression were assessed by investigators using 2014 Lugano Classification. The primary endpoint was PFS; secondary endpoints included OS, event-free survival, patient-reported outcomes (PROs), and safety. Results: 994 pts were enrolled from 7/9/19 to 10/5/22; 976 were eligible and randomized to N-AVD (n=489) or BV-AVD (n=487). Median age was 27y (range, 12-83y), 56% of pts were male, 76% were white, 12% were black, and 13% were Hispanic. 24% of pts were < 18y, 10% were > 60y, and 32% had IPS 4-7. So far, < 1% of pts received RT. At the planned 2nd interim analysis (50% of total PFS events) the SWOG Data and Safety Monitoring Committee recommended to report the primary results because the primary PFS endpoint crossed the protocol-specified conservative statistical boundary. 30 PFS events occurred after N-AVD vs 58 events after BV-AVD. With a median follow-up of 12.1 months, PFS was superior in the N-AVD arm [HR 0.48, 99% CI 0.27-0.87, one-sided p=0.0005); 1y PFS: N-AVD, 94%, BV-AVD, 86%. 11 deaths (7 due to adverse events, AE) were observed after BV-AVD compared to 4 after N-AVD (3 due to AE). The rate of grade (gr) ≥ 3 hematologic AE was 48.4% (45.1% gr ≥ 3 neutropenia) after N-AVD compared to 30.5% (23.9% gr ≥ 3 neutropenia) after BV-AVD. Rates (any gr) of febrile neutropenia (5.6% N vs 6.4% BV), pneumonitis (2.0% N vs 3.2% BV), ALT elevation (30.7% N vs 39.8% BV), and colitis (1% N vs 1.3% BV) were similar. Hypo/hyperthyroidism was more frequent after N-AVD (7%/3% N vs <1% BV) while peripheral neuropathy (any gr) was more common after BV-AVD (sensory: 28.1% N vs 54.2% BV; motor: 4% N vs 6.8% BV). Conclusions: N-AVD improved PFS vs BV-AVD in pts with AS HL. Few immune AEs were observed and < 1% of pts received RT. Longer follow-up is needed to assess OS and PROs. S1826, the largest HL study in NCTN history, is a key step towards harmonizing the pediatric and adult treatment of AS HL.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
