Nivolumab Plus Ipilimumab for Treatment-Naïve Metastatic Uveal Melanoma: An Open-Label, Multicenter, Phase II Trial by the Spanish Multidisciplinary Melanoma Group (GEM-1402).

PURPOSE: This study aimed to assess the efficacy of the combination of nivolumab (nivo) plus ipilimumab (ipi) as a first-line therapy with respect to the 12-month overall survival (OS) in patients with metastatic uveal melanoma (MUM) who are not eligible for liver resection. METHODS: This was a single-arm, phase II trial led by the Spanish Multidisciplinary Melanoma Group (GEM) on nivo plus ipi for systemic treatment-naïve patients of age > 18 years, with histologically confirmed MUM, Eastern Cooperative Oncology Group-PS 0/1, and confirmed progressive metastatic disease (M1). Nivo (1 mg/kg once every 3 weeks) and ipi (3 mg/kg once every 3 weeks) were administered during four inductions, followed by nivo (3 mg/kg once every 2 weeks) until progressive disease, toxicity, or withdrawal. The primary end point was 12-month OS. OS, progression-free survival (PFS), and overall response rate were evaluated every 6 weeks using RECIST (v1.1). Safety was also evaluated. Logistic regression and Cox proportional hazard models comprising relevant clinical factors were used to evaluate the potential association with response to treatment and survival. Cytokines were quantified in serum samples for their putative role in immune modulation/angiogenesis and/or earlier evidence of involvement in immunotherapy. RESULTS: A total of 52 patients with a median age of 59 years (range, 26-84 years) were enrolled. Overall, 78.8%, 56%, and 32% of patients had liver M1, extra-liver M1, and elevated lactate dehydrogenase. Stable disease was the most common outcome (51.9%). The primary end point was 12-month OS, which was 51.9% (95% CI, 38.3 to 65.5). The median OS and PFS were 12.7 months and 3.0 months, respectively. PFS was influenced by higher LDH values. CONCLUSIONS: Nivo plus ipi in the first-line setting for MUM showed a modest improvement in OS over historical benchmarks of chemotherapy, with a manageable toxicity profile.

Late toxicity after radical treatment for locally advanced head and neck cancer.

BACKGROUND: Multimodal treatment for locally advanced head and neck carcinomas (LAHNC) has been reported to improve survival. However, it is less clear to what extent this survival gain is given at the expense of an impact on the quality of life of our patients. Our aim is to analyze the ongoing late toxic effects among long survivors, to determine how much these impairments affect their QoL, and if there is any factor that clearly impacts on this toxicity. METHODS: 152 Patients diagnosed with LAHNC were treated radically in our clinical practice, either with concomitant chemoradiotherapy or bioradiotherapy, with or without induction chemotherapy. We prospectively assessed these patients' treatment-related late toxicities according to the Radiation Therapy Oncology Group scoring system, and patients answered a QoL question to subjectively evaluate the degree of impact caused by these sequelae in their daily life. Multivariate logistic regressions were performed to detect factors that could influence in toxicity. RESULTS: 21.9% Patients experienced grade 3-4 toxicity. Concomitant chemoradiation with cisplatin was found to be a risk factor of moderate and severe late toxicity compared to concomitant cetuximab in the adjusted analysis by RT fractionation. OR for moderate toxicity 0.292 (CI: 0.125-0.680, p=0.004); OR for severe toxicity: 0.299 (CI: 0.0909-0.999, p=0.05). Induction chemotherapy was found to be a protective factor for moderate late toxicity compared to concomitant treatment alone. CONCLUSION: Patients treated with concomitant chemoradiation with cisplatin have significantly more late toxicity compared to bioradiotherapy, whereas induction chemotherapy prevents from developing moderate late toxicity.
