Uveal melanoma is a common intraocular malignant tumor that is uniformly fatal once metastatic. No effective adjuvant therapy currently exists to reduce the risk of distant metastasis after definitive treatment of the primary lesion. Immunotherapy has been used effectively in the adjuvant setting in locally advanced cutaneous melanoma. We performed a Phase I/II clinical trial of adjuvant ipilimumab in high-risk primary uveal melanoma with distant metastasis-free survival (DMFS) as the primary ob ...[more]

Project description:IntroductionApproximately 40% of patients with uveal melanoma (UM) will develop metastatic disease. Tumors measuring at least 12mm in basal diameter with a class 2 signature, as defined by a widely used gene expression-profiling test, are associated with significantly higher risk of metastasis, with a median time to recurrence of 32 months. No therapy has been shown to reduce this risk.Materials and methodsThis was a single-arm, multicenter study in patients with high-risk UM who received definitive treatment of primary disease and had no evidence of metastasis. Patients were consecutively enrolled to receive 12 four-week cycles of adjuvant crizotinib at a starting dose of 250mg twice daily and were subsequently monitored for 36 months. The primary outcome of this study was to assess recurrence-free survival (RFS) of patients with high-risk UM who received adjuvant crizotinib.Results34 patients enrolled and received at least one dose of crizotinib. Two patients were unevaluable due to early withdrawal and loss to follow-up, leaving 32 patients evaluable for efficacy. Eight patients (25%) did not complete the planned 48-week course of treatment due to disease recurrence (n=5) or toxicity (n=3). All patients experienced at least one adverse event (AE), with 11/34 (32%) experiencing a Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4 AE. After a median duration of follow up of 47.1 months, 21 patients developed distant recurrent disease. The median RFS was 34.9 months (95% CI (Confidence Interval), 23-55 months), with a 32-month recurrence rate of 50% (95% CI, 33-67%). Analysis of protein contents from peripheral blood extracellular vesicles in a subset of patient samples from baseline, on-treatment, and off-treatment, revealed a change in protein content associated with crizotinib exposure, however without a clear association with disease outcome.ConclusionsThe use of adjuvant crizotinib in patients with high-risk UM did not result in improved RFS when compared to historical controls. Analysis of blood extracellular vesicles revealed changes in protein content associated with treatment, raising the possibility of future use as a biomarker. Further investigation of adjuvant treatment options are necessary for this challenging disease.

Project description:We conducted a randomized phase III trial to evaluate whether adjuvant pembrolizumab for one year (647 patients) improved recurrence-free survival (RFS) or overall survival (OS) in comparison with high-dose IFNα-2b for one year or ipilimumab for up to three years (654 patients), the approved standard-of-care adjuvant immunotherapies at the time of enrollment for patients with high-risk resected melanoma. At a median follow-up of 47.5 months, pembrolizumab was associated with significantly longer RFS than prior standard-of-care adjuvant immunotherapies [HR, 0.77; 99.62% confidence interval (CI), 0.59-0.99; P = 0.002]. There was no statistically significant association with OS among all patients (HR, 0.82; 96.3% CI, 0.61-1.09; P = 0.15). Proportions of treatment-related adverse events of grades 3 to 5 were 19.5% with pembrolizumab, 71.2% with IFNα-2b, and 49.2% with ipilimumab. Therefore, adjuvant pembrolizumab significantly improved RFS but not OS compared with the prior standard-of-care immunotherapies for patients with high-risk resected melanoma.SignificanceAdjuvant PD-1 blockade therapy decreases the rates of recurrence, but not survival, in patients with surgically resectable melanoma, substituting the prior standard-of-care immunotherapies for this cancer.

Project description:Background: Adjuvant therapy for high-risk resected melanoma with PD-1 blockade results in median relapse-free survival (RFS) of 5 years. The addition of low dose ipilimumab (IPI) to a regimen of nivolumab (NIVO) in Checkmate-915, did not result in increased RFS. A pilot phase II adjuvant study of either standard or low dose IPI with NIVO was conducted at two centers to evaluate RFS with correlative studies. Methods: Patients (pts) with resected stages IIIB/IIIC/IV melanoma received either IPI 3mg/kg and NIVO 1mg/kg (cohort 4) or IPI 1mg/kg and NIVO 3mg/kg (cohorts 5 and 6) induction therapy every three weeks for 12 weeks, followed by maintenance NIVO. Peripheral blood samples at baseline and on-treatment were assessed by flow cytometry for potential biomarkers. Peripheral CD8+ T-cells were assessed by RNA-Seq. Results: High rates of grade 3-4 adverse events precluded completion of induction therapy in 50%, 35% and 7% of patients in cohorts 4, 5 and 6 respectively. At a median of 63.9 months of follow up, 16/56 pts (29%) relapsed. For all patients, at five-years, RFS was 71% (95% CI: 60, 84), and overall survival was 94% (95% CI: 88, 100). Expansion of CD3+CD4+CD38+CD127-GARP- T-cells, an on-treatment increase in CD39 expression in CD8+ T-cells, and T-cell expression of phosphorylated STAT2 and STAT5 were associated with relapse. Conclusions: Adjuvant IPI/NIVO at the induction doses used resulted in excellent relapse-free survival, albeit with a high rate of grade 3-4 adverse events. Biomarker analyses highlight an association of ectoenzyme-expressing T-cells and STAT signaling pathways with relapse.

Project description:BackgroundAdjuvant ipilimumab was found to improve the overall survival and reduce toxicity compared to high-dose interferon (HDI) in patients with resected, high-risk melanoma. However, the cost of ipilimumab is substantially higher than HDI. This study evaluates the cost-effectiveness of ipilimumab as an adjuvant treatment in melanoma from a healthcare perspective.MethodsWe designed a Markov model simulating resected, high-risk melanoma patients receiving either ipilimumab or HDI. Transition probabilities, including risks of survival, disease progression, and toxicity, were ascertained from clinical trial data. Costs and quality of life measurements (health utilities) were extracted from the literature. Incremental cost-effectiveness ratios (ICERs), defined as incremental costs divided by incremental quality-adjusted life-years (QALYs), assessed cost-effectiveness. ICERs <$100,000/QALY were deemed cost-effective. We measured model uncertainty with one-way and probabilistic sensitivity analyses.ResultsIn our base case model, ipilimumab increased costs by $107,100 and increased effectiveness by 0.43 QALY, yielding an ICER of $392,600/QALY. Our model was moderately sensitive to the costs of ipilimumab, though the cost of ipilimumab would need to decrease by 44% for ipilimumab to become cost-effective compared to HDI. The model was not sensitive to survival, toxicity, or other costs. Probabilistic sensitivity analysis showed that HDI would remain the cost-effective treatment option 96.2% of the time at a willingness-to-pay threshold of $100,000/QALY.ConclusionsAdjuvant ipilimumab increases the survival and decreases the toxicity compared to HDI in resected, high-risk melanoma patients, though this would not be considered cost-effective due to the high price of ipilimumab.

Project description:The survival of patients with uveal melanoma remains poor because of the development of metastatic disease. Adjuvant therapy after treatment of the primary tumor has been tested but has not been shown to prevent the development of metastasis. Several new approaches are being developed. Cytotoxic and immunotherapeutic regimens are being more rationally applied using tumor genetic criteria to better identify patients at risk. Trials in the adjuvant setting of novel immunotherapeutic and targeted agents active in the metastatic setting are being developed, as are approaches to promote cellular differentiation and dormancy. The rarity and biology of uveal melanoma present challenges. Participation in well-designed, scientifically sound clinical trials is critical.

Project description:BackgroundOn the basis of data from a phase 2 trial that compared the checkpoint inhibitor ipilimumab at doses of 0.3 mg, 3 mg, and 10 mg per kilogram of body weight in patients with advanced melanoma, this phase 3 trial evaluated ipilimumab at a dose of 10 mg per kilogram in patients who had undergone complete resection of stage III melanoma.MethodsAfter patients had undergone complete resection of stage III cutaneous melanoma, we randomly assigned them to receive ipilimumab at a dose of 10 mg per kilogram (475 patients) or placebo (476) every 3 weeks for four doses, then every 3 months for up to 3 years or until disease recurrence or an unacceptable level of toxic effects occurred. Recurrence-free survival was the primary end point. Secondary end points included overall survival, distant metastasis-free survival, and safety.ResultsAt a median follow-up of 5.3 years, the 5-year rate of recurrence-free survival was 40.8% in the ipilimumab group, as compared with 30.3% in the placebo group (hazard ratio for recurrence or death, 0.76; 95% confidence interval [CI], 0.64 to 0.89; P<0.001). The rate of overall survival at 5 years was 65.4% in the ipilimumab group, as compared with 54.4% in the placebo group (hazard ratio for death, 0.72; 95.1% CI, 0.58 to 0.88; P=0.001). The rate of distant metastasis-free survival at 5 years was 48.3% in the ipilimumab group, as compared with 38.9% in the placebo group (hazard ratio for death or distant metastasis, 0.76; 95.8% CI, 0.64 to 0.92; P=0.002). Adverse events of grade 3 or 4 occurred in 54.1% of the patients in the ipilimumab group and in 26.2% of those in the placebo group. Immune-related adverse events of grade 3 or 4 occurred in 41.6% of the patients in the ipilimumab group and in 2.7% of those in the placebo group. In the ipilimumab group, 5 patients (1.1%) died owing to immune-related adverse events.ConclusionsAs adjuvant therapy for high-risk stage III melanoma, ipilimumab at a dose of 10 mg per kilogram resulted in significantly higher rates of recurrence-free survival, overall survival, and distant metastasis-free survival than placebo. There were more immune-related adverse events with ipilimumab than with placebo. (Funded by Bristol-Myers Squibb; ClinicalTrials.gov number, NCT00636168 , and EudraCT number, 2007-001974-10 .).

Project description:Uveal melanoma (UM) is the most common intraocular malignancy in adults. In contrast to cutaneous melanoma (CM), there is no standard therapy, and the efficacy and safety of dual checkpoint blockade with nivolumab and ipilimumab is not well defined. We conducted a retrospective analysis of patients with metastatic UM (mUM) who received treatment with ipilimumab plus nivolumab across 14 academic medical centers. Toxicity was graded using National Cancer Institute Common Terminology Criteria for Adverse Events V.5.0. Progression-free survival (PFS) and overall survival (OS) were calculated using Kaplan-Meier methodology. 89 eligible patients were identified. 45% had received prior therapy, which included liver directed therapy (29%), immunotherapy (21%), targeted therapy (10%) and radiation (16%). Patients received a median 3 cycles of ipilimumab plus nivolumab. The median follow-up time was 9.2 months. Overall response rate was 11.6%. One patient achieved complete response (1%), 9 patients had partial response (10%), 21 patients had stable disease (24%) and 55 patients had progressive disease (62%). Median OS from treatment initiation was 15 months and median PFS was 2.7 months. Overall, 82 (92%) of patients discontinued treatment, 34 due to toxicity and 27 due to progressive disease. Common immune-related adverse events were colitis/diarrhea (32%), fatigue (23%), rash (21%) and transaminitis (21%). Dual checkpoint inhibition yielded higher response rates than previous reports of single-agent immunotherapy in patients with mUM, but the efficacy is lower than in metastatic CM. The median OS of 15 months suggests that the rate of clinical benefit may be larger than the modest response rate.

Project description:Uveal melanoma (UM) is a rare ocular malignancy which originates in the uveal tract, and often gives rise to metastases. Potential targets for immune checkpoint inhibition are lymphocyte-activation gene 3 (LAG3) and its ligands. We set out to analyse the distribution of these molecules in UM. The expression of mRNA was determined using an Illumina array in 64 primary UM from Leiden. The T lymphocyte fraction was determined by digital droplet PCR. In a second cohort of 15 cases from Leiden, mRNA expression was studied by Fluidigm qPCR, while a third cohort consisted of 80 UM from TCGA. In the first Leiden cohort, LAG3 expression was associated with the presence of epithelioid cells (p = 0.002), monosomy of chromosome 3 (p = 0.004), and loss of BAP1 staining (p = 0.001). In this Leiden cohort as well as in the TCGA cohort, LAG3 expression correlated positively with the expression of its ligands: LSECtin, Galectin-3, and the HLA class II molecules HLA-DR, HLA-DQ, and HLA-DP (all p < 0.001). Furthermore, ligands Galectin-3 and HLA class II were increased in monosomy 3 tumours and the expression of LAG3 correlated with the presence of an inflammatory phenotype (T cell fraction, macrophages, HLA-A and HLA-B expression: all p < 0.001). High expression levels of LAG3 (p = 0.01), Galectin-3 (p = 0.001), HLA-DRA1 (p = 0.002), HLA-DQA1 (p = 0.04), HLA-DQB2 (p = 0.03), and HLA-DPA1 (p = 0.007) were associated with bad survival. We conclude that expression of the LAG ligands Galectin-3 and HLA class II strongly correlates with LAG3 expression and all are increased in UM with Monosomy 3/BAP1 loss. The distribution suggests a potential benefit of monoclonal antibodies against LAG3 or Galectin-3 as adjuvant treatment in patients with high-risk UM.

Project description:Metastatic uveal melanoma (UM) remains challenging to treat, with objective response rates to immune checkpoint blockade (ICB) being much lower than in primary cutaneous melanoma (CM). Besides a lower mutational burden, the overall immune-excluded tumor microenvironment of UM might contribute to the poor response rate. We therefore aimed at targeting deficiency in argininosuccinate synthase 1, which is a key metabolic feature of UM. This study aims at investigating the safety and tolerability of a triple combination consisting of ipilimumab and nivolumab immunotherapy and the metabolic therapy, ADI-PEG 20. Nine patients were enrolled in this pilot study. The combination therapy was safe and tolerable with an absence of immune-related adverse events (irAE) of special interest, but with four of nine patients experiencing a CTCAE grade 3 AE. No objective responses were observed. All except one patient developed anti-drug antibodies (ADA) within a month of the treatment initiation and therefore did not maintain arginine depletion. Further, an IFNg-dependent inflammatory signature was observed in metastatic lesions in patients pre-treated with ICB compared with patients with no pretreatment. Multiplex immunohistochemistry demonstrated variable presence of tumor infiltrating CD8 lymphocytes and PD-L1 expression at the baseline in metastases.
