FRACTION-RCC: Innovative, high-throughput assessment of nivolumab + ipilimumab for treatment-refractory advanced renal cell carcinoma (aRCC).
Notice bibliographique
Résumé
5007 Background: The immuno-oncology (I-O) combination nivolumab + ipilimumab (NIVO+IPI) is approved for first-line (1L) and NIVO is approved for second-line treatment post TKI therapy in aRCC. The open-label, randomized, phase 2 Fast Real-Time Assessment of Combination Therapies in Immuno-Oncology (FRACTION-RCC; NCT02996110) platform study has an adaptive design allowing rapid evaluation of I-O therapies, including NIVO+IPI or other investigational combinations. This FRACTION analysis reports preliminary outcomes with NIVO+IPI in aRCC pts after progression on checkpoint inhibitor therapy. Methods: All pts, except 1, had previously received and progressed on checkpoint inhibitor treatment. Pts received NIVO+IPI (NIVO 3 mg/kg + IPI 1 mg/kg Q3W ×4, then after 6 weeks, NIVO 480 mg Q4W), up to 2 years or until progression, toxicity, or protocol-specified discontinuation. Primary endpoints were confirmed objective response rate (ORR; per investigator using RECIST v1.1), duration of response (DOR), and progression-free survival probability at week 24. Safety outcomes were reported. Results: 46 pts were randomized to NIVO+IPI. Pts had 0 (n = 1), 1 (n = 10), 2 (n = 12), 3 (n = 10), or ≥4 (n = 13) prior lines of therapy. All pretreated pts had prior anti-PD-(L)1-, none had prior anti-CTLA-4- therapy, and 37 had prior TKI-based therapy; 45 pts progressed on anti-PD-(L)1 as the most recent therapy. Most pts had clear cell aRCC (n = 44). After a median study follow-up of 8.9 months, ORR was 15.2%; no pts achieved complete response and 7 achieved partial response. DOR ranged from 2–19+ months (n = 7); 5 pts had ongoing response. Six of 7 responders had received ≥2 prior lines of therapy. Any-grade treatment-related adverse events (AEs) were reported in 36 pts (78.3%; fatigue, rash [both 19.6%], and diarrhea [17.4%] were most common). Grade 3–4 treatment-related AEs were reported in 13 pts (28.3%; diarrhea [8.7%], ↑amylase and ↑lipase [both 6.5%] were most common). Treatment-related immune-mediated AEs of any grade were reported in 22 pts (47.8%; rash [19.6%], diarrhea [17.4%], and ↑alanine aminotransferase [8.7%]). No treatment-related deaths were reported. Updated and expanded results with an additional 3 months of follow-up will be presented. Conclusions: These results suggest that NIVO+IPI may provide durable partial response in some pts with prior progression on checkpoint inhibitors, including some heavily pretreated pts. The safety profile of NIVO+IPI in FRACTION pts was similar to historic data in aRCC with this combination. Clinical trial information: NCT02996110 .

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.
