    Abstract: e21582 Background: Both chemotherapy and high-dose IFN-α2b (HDI) are effective treatment options in adjuvant setting for patients with resectable mucosal melanoma (MM). However, it is still unknown whether Ki67 level affects the selection of chemotherapy and HDI. Methods: Data from resected MM patients diagnosed as MM in Peking Cancer Hospital, were retrospectively collected and analyzed. Key inclusion criteria were: (1) diagnosed as resectable MM, with the date between Jan. 1, 2010, and Dec. 31, 2018; (2) Ki67 was identified by immunohistochemical staining; (3) received TMZ-based adjuvant chemotherapy or HDI. All patients were divided into two subgroups according to the Ki67 level proposed by previous publications: low ( 〈 30%), high ( 〉 = 30%). Relapse-free survival (RFS) and melanoma-specific survival (MSS) were compared across different subgroups by log-rank tests. Multivariate Cox proportional hazards models were used to calculate hazard ratios (HRs), controlling for age, sex, primary site, lymphatic metastasis, LDH level, and gene mutational status (BRAF, c-KIT and NRAS). Results: In total, 1106 MM patients were screened and 175 met the inclusion criteria for analysis. 100 and 75 patients received temozolomide (TMZ)-based adjuvant chemotherapy and HDI therapy, respectively. Patients who received adjuvant chemotherapy had a superior RFS (21.0 vs. 9.6 months, HR = 0.47, P = 0.002) as compared to those with HDI, but no significant difference for MSS (45.9 vs. 37.6 months, HR = 0.63, P = 0.396). Longer RFS and MSS were observed in the ki67-low subgroup (HRs were 0.51, 95%CI 0.34-0.76 and 0.41, 95%CI 0.24-0.68 for RFS and MSS, respectively). For patients with low Ki67 ( 〈 30%), two regimens showed no statistically different RFS (33.9 vs. 22.7 months, HR = 0.76, P = 0.329) and MSS (114.5 vs. 61.4 months, HR = 1.23, P = 0.967). However, for those with high Ki67, TMZ-based chemotherapy achieved an extended RFS compared with HDI (18.0 vs. 6.7 months, HR = 0.36, P 〈 0.001) and a trend toward improvement for MSS (41.4 vs. 25.1 months, HR = 0.47, P = 0.067). Conclusions: Ki67 level is an independent negative prognostic factor and impacts the selection of adjuvant treatment options for MM patients. Chemotherapy should be considered as the preference for patients with Ki67 〉 = 30%.

    Abstract: Metastatic mucosal melanoma responds poorly to anti–programmed cell death-1 (PD-1) monotherapy. Vascular endothelial growth factor (VEGF) has been shown to play an important immunosuppressive role in the tumor microenvironment. The combination of VEGF inhibition and PD-1 blockade provides therapeutic opportunities for patients refractory to either therapy alone. PATIENTS AND METHODS We conducted a single-center, phase IB trial evaluating the safety and preliminary efficacy of toripalimab, a humanized immunoglobulin G 4 monoclonal antibody against PD-1 in combination with the VEGF receptor inhibitor axitinib in patients with advanced melanoma, including patients with chemotherapy-naïve mucosal melanomas (88%). Patients received toripalimab at 1 or 3 mg/kg via intravenous infusion every 2 weeks, in combination with axitinib 5 mg orally twice a day, in a dose-escalation and cohort-expansion study until confirmed disease progression, unacceptable toxicity, or voluntary withdrawal. The primary objective was safety. Secondary objectives included efficacy, pharmacokinetics, pharmacodynamics, immunogenicity, and tumor tissue biomarkers. RESULTS Thirty-three patients were enrolled. No dose-limiting toxicities were observed. Ninety-seven percent of patients experienced treatment-related adverse events (TRAEs). The most common TRAEs were mild (grade 1 or 2) and included diarrhea, proteinuria, hand and foot syndrome, fatigue, AST or ALT elevation, hypertension, hypo- or hyperthyroidism, and rash. Grade 3 or greater TRAEs occurred in 39.4% of patients. By the cutoff date, among 29 patients with chemotherapy-naïve mucosal melanoma, 14 patients (48.3%; 95% CI, 29.4% to 67.5%) achieved objective response, and the median progression-free survival time was 7.5 months (95% CI, 3.7 months to not reached) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CONCLUSION The combination of toripalimab plus axitinib was tolerable and showed promising antitumor activity in patients with treatment-naïve metastatic mucosal melanoma. Patients enrolled in this study were all Asian, and this combination therapy must be validated in a randomized phase III trial that includes a non-Asian population before it can become a standard of care.

    Frequent Genetic Aberrations in the CDK4 Pathway in Acral Melanoma Indicate the Potential for CDK4/6 Inhibitors in Targeted Therapy
    American Association for Cancer Research (AACR) ; 2017

    Abstract: Purpose: Effective therapies for the majority of metastatic acral melanoma patients have not been established. Thus, we investigated genetic aberrations of CDK4 pathway in acral melanoma and evaluated the efficacy of CDK4/6 inhibitors in targeted therapy of acral melanoma. Experimental Design: A total of 514 primary acral melanoma samples were examined for the copy number variations (CNV) of CDK4 pathway-related genes, including Cdk4, Ccnd1, and P16INK4a, by QuantiGenePlex DNA Assay. The sensitivity of established acral melanoma cell lines and patient-derived xenograft (PDX) containing typical CDK4 aberrations to CDK4/6 inhibitors was evaluated. Results: Among the 514 samples, 203 cases, 137 cases, and 310 cases, respectively, showed Cdk4 gain (39.5%), Ccnd1 gain (26.7%), and P16INK4a loss (60.3%). The overall frequency of acral melanomas that contain at least one aberration in Cdk4, Ccnd1, and P16INK4a was 82.7%. The median overall survival time for acral melanoma patients with concurrent Cdk4 gain with P16INK4a loss was significantly shorter than that for patients without such aberrations (P = 0.005). The pan-CDK inhibitor AT7519 and selective CDK4/6 inhibitor PD0332991 could inhibit the cell viability of acral melanoma cells and the tumor growth of PDX with Cdk4 gain plus Ccnd1 gain, Cdk4 gain plus P16INK4a loss, and Ccnd1 gain plus P16INK4a loss. Conclusions: Genetic aberration of CDK4 pathway is a frequent event in acral melanoma. Acral melanoma cell lines and PDX containing CDK4 pathway aberrations are sensitive to CDK4/6 inhibitors. Our study provides evidence for the testing of CDK4/6 inhibitors in acral melanoma patients. Clin Cancer Res; 23(22); 6946–57. ©2017 AACR.

    Abstract: 9521 Background: Mucosal melanoma is rare and associated with extremely poor prognosis. There was no standard treatment for advanced mucosal melanoma patients. BEAM study had demonstrated the effectivity and safety of bevacizumab combined with carboplatin plus paclitaxel in patients with previously untreated metastatic melanoma. This study was to evaluate the activity of bevacizumab combined with carboplatin plus paclitaxel in Patients with Previously Untreated Advanced Mucosal Melanoma. Methods: This study is an open-label, multicenter, randomized phase II trial. Eligible patients had metastatic, recurrent, or unresectable mucosal melanoma and no received any systemic therapy before enrollment. Patients were randomly allocated in a 2:1 ratio to receive bevacizumab (CPB arm, 5mg/kg every two weeks) or placebo (CP arm) with carboplatin (area under the curve, 5) plus paclitaxel (175 mg/m 2 ). Treatment was continued for both groups until disease progression, unacceptable toxicity, death, or withdrawal of consent. The primary study endpoint is progress-free survival (PFS). Overall survival, disease control rate, and safety will also be assessed. Results: The first patient visit was December 1st, 2013, and the final data cutoff was August 30th, 2018. At that time, 114 patients were randomly assigned to receive CP or CPB therapy. Median PFS was 3.2 months for the CP arm and 4.7 months for the CPB arm (HR, 0.50; 95% CI, 0.33-0.72; P = 0.001). Median OS was 9.0 months in the CP arm versus 12.9 months in the CPB arm (HR, 0.61; 95% CI, 0.40-0.92; P = 0.02). The PFS was longer in the CPB arm in the subgroups of patients with neutrophil-to-lymphocyte ratio (NLR) more than 4 and patients with abnormal lactate dehydrogenase concentration (1.2 v 3.0 months, HR, 0.38; 2.0 v 4.7 months, HR, 0.39, respectively). Multivariate analysis using the Cox model showed that combination with bevacizumab was the predictor for better disease control and survival (PFS: HR 0.400, 95% CI 0.251-0.636, P 〈 0.001; OS: HR 0.505, 95% CI 0.313-0.814, P = 0.005). No new safety signals were observed. Conclusions: To our knowledge this is the largest study about advanced mucosal melanoma. This study demonstrated that bevacizumab in combination with carboplatin plus paclitaxel is active and safe regimen as first line treatment in patients with in advanced mucosal melanoma. A phase III study will be necessary to confirm the benefit, especially in some special setting such as elevated NLR and elevated LDH subgroups. Clinical trial information: NCT02023710.

    Abstract: e21008 Background: Mucosal melanomas (MM) have a significantly worse survival outcome than cutaneous melanoma. The current staging rules for cutaneous melanoma do not apply to mucosal melanoma. Our previous studies have demonstrated mucosal melanomas arising from different anatomic sites can be staged and treated as a single disease entity. We are recommending a new evidence-based staging system for mucosal melanoma. Methods: The mucosal melanoma staging recommendations were made on the basis of a multivariate analysis of 543 patients with stages I, II, and III melanoma and 547 patients with stage IV melanoma to clarify TNM classifications and stage grouping criteria. Results: New staging definitions include the following: (1) in patients with localized melanoma, the depth of tumor invasion of the primary melanomas is the most dominant prognostic factor: T1 for tumor invading mucosa or submucosa; T2 for tumor invading the muscularis propria; T3 for tumor invading adventitia; T4 for tumor invading adjacent structures; (2) The dominant prognostic factor for regional nodal metastases is the number of metastatic nodes: N1 for 1 regional metastatic node; N2 for 2 or more regional metastatic nodes; (3) On the basis of a multivariate analysis of patients with distant metastases, the dominant component in defining the M category is the site of distant metastases (M1:lung only vs. M2:liver only vs. M3:brain only vs. M4:all other visceral metastatic sites). An elevated serum lactate dehydrogenase level would be designated in parenthesis. The staging grouping of mucosal melanoma can be defined as follow: (1) stage I: T1N0M0; (2) Stage II:T2-4N0M0; (3) Stage IIIA: T1-4N1M0, Stage IIIB: T1-4N2M0; (4) Stage IV: anyTanyNM1-4. Conclusions: Using an evidence-based approach, the proposed staging system of mucosal melanoma is the first to be established that reflects our improved understanding of this disease.

    Abstract: e21545 Background: Melanoma pts with liver metastasis has poor prognosis and reduced response to systemic immunotherapy. Oncolytic herpes simplex virus 2 (OH2) is an oncolytic virus derived from herpes simplex virus type 2. PD-1 antibody combined with intrahepatic oncolytic virus intralesional injection had shown preliminary efficacy in previous clinical trial. The radiation of liver metastasis might exert action on its tumor microenvironment and get benefit from immunotherapy combination. So we perform this phase I study to assess the safety and efficacy of OH2 and pucotenlimab (a humanized immunoglobulin G4 monoclonal antibody) combine with liver metastasis radiation in melanoma pts. Methods: Eligible pts included those over 18 with injectable liver metastasis confirmed by biopsy with or without extra-hepatic metastasis; the ocular melanoma and brain metastasis were excluded. Pts received intravenous Pucotenlimab Q3W combined with ultrasound guided intrahepatic injection (metatstasis lesion) of OH2 Q2W (10 7 CCID50/mL, 8ml per injection) after stereotactic body radiotherapy (24-30Gy/3Fx) of liver metastasis. Liver biopsy performed at baseline and first tumor evaluation (8-12weeks). The primary endpoint was ORR; secondary:toxicity, DCR, PFS and OS. Results: From Dec 2021 to Jan 2023, 10 pts were eligible and enrolled. Baseline characteristics: 70% got previous treatment; LDH＞ULN 50.0%; 90% got extra-hepatic metastasis; median size of ed lesions: 36mm(19-120mm); median number of liver metastasis: 5.5. Among these pts, 5 pts could be evaluated for efficacy (follow-up 10.0 m). The global ORR by investigator was 40.0% (2/5), DCR 80% (4/5). Biopsies of 4 pts for injected lesions at 8 to 12 weeks after first injection were examined to determine the situation of tumor regression and TIL infiltration. Among them, 2 pts ( 1 PR and 1 SD) had no tumor cells residual by immunohistochemistry in biopsies with impressive TIL infiltration, both of them showed PFS more than12.0 months. Most adverse events (AE) were grade 1-2. Only one pts had grade 3-4 thrombocytopenia, with treatment modified. No treatment-related deaths occurred. The median PFS was not reached and now in follow up. Conclusions: Systemic anti-PD-1 plus intralesional injection of Oncolytic virus combined with radiotherapy has shown remarkable ORR and pathological response in melanoma pts with liver metastases with manageable toxicity. Clinical trial information: NCT05068453 . [Table: see text]

    Abstract: 341 Background: Xp11.2 translocation renal cell carcinoma (RCC) is a unique RCC subtype with high malignant potential and poor prognosis, its natural course and response to systemic therapy are not fully understood. We analyzed the clinic features of this distinct entity and the benefit of systemic therapy in these patients. Methods: Between May 2006 and December 2019, 1113 consecutive patients diagnosed with RCC from Peking university cancer hospital (Beijing, China) were reviewed, data of the clinical characteristics and outcome of patients with metastatic Xp11.2 RCC were retrospectively collected. Tumor response to systemic therapy was evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) criteria. The Kaplan-Meier method was used to estimate progression-free survival (PFS) and overall survival (OS) distributions. Results: Metastatic Xp11.2 tRCC was found in 45 patients. The median PFS and median OS was 7.4 months (4.5 - 8.8) and 17.9 months (12.4 - 24.4), respectively. First-line treatment mainly included sunitinib (n = 14), sorafenib (n = 15), axitinib (n = 6), and pazopanib (n = 5), and the median PFS of these regimens were 7.4 months, 5.4 months, 9.4 months, 8.9 months, respectively. Two patients who received Vascular endothelial growth factor receptor - tyrosine kinase inhibitor (VEGFR-TKI) plus immune checkpoint inhibitor (ICI) as first line therapy had a PFS of more than 16.6 months and more than 25.6 months, respectively. Twenty-four patients received subsequent therapies, which included VEGFR-TKI/ICI, axitinib and mTOR inhibitor, the median PFS for these regimens was 8.5, 7.2 and 2.0 months, respectively. Patients with serous cavity effusion or IMDC poor risk groups had significantly shorter median PFS and median OS. Conclusions: Metastatic Xp11.2 tRCC is an aggressive disease. VEGFR-TKI agents appeared to demonstrate some efficacy, VEGFR-TKI/ICI combination might be a useful tool for the treatment of metastatic Xp11.2 tRCC.

    Abstract: 10040 Background: Vorolanib (CM082) is a multi-target tyrosine kinase inhibitor including VEGF, PDGF, c-kit, and Flt-3. Toripalimab (JS001) is a humanized IgG4 mAb against programmed death-1 (PD-1) with clinical activity in metastasis melanoma but not in its mucosal subtype. In this phase II study (NCT03602547), we investigated the safety and efficacy of CM082 in combination with JS001 in patients (pts) with advanced mucosal melanoma. Methods: The study enrolled pts from 18 to 75 years-old with histologically confirmed metastatic mucosal melanoma, ECOG PS 0-1, no prior systemic anti-cancer treatment. Eligible pts were treated with CM082 tablet (150 or 200 mg once daily) combined with JS001 (240mg every 2 weeks, IV, Q2W) until confirmed disease progression or unacceptable toxicity. Clinical response was evaluated every 8 week. The primary endpoint was overall response rate (ORR) using RECIST v1.1. Secondary endpoints included progression-free survival (PFS), overall survival (OS), disease control rate (DCR), duration of remission (DOR), and time to first remission (TTR) according to RECIST v1.1 and iRECIST. The safety was also assessed. Results: Between July 2018 and April 12, 2019, 40 pts (19 pts in 150mg group; 21 pts in 200mg group) were enrolled and 38 pts were evaluable for tumor response (150mg n = 18, 200mg n = 20), with 4 (22.2%) confirmed partial response (PR), 6 (33.3%) stable disease (SD) and 8 (44.4%) progression disease (PD) in the 150mg CM082 group; 3 (15%) PRs (including 2 unconfirmed), 10 (50%) SD, and 7 (35%) PD were reported in the 200mg CM082 group. Tumors shrank in 10 pts (56%) in the 150mg group and 10 pts (50%) in the 200mg group. At data cut-off (November 28, 2019), 29 pts had PFS events (150mg n = 12; 200mg n = 17). The median PFS was 5.7 (95% CI 2.0, NE) months and 5.6 (1.9, 7.7) months in the two groups, respectively. The most common treatment-related adverse events (AEs) were grade 1 or 2, including leukopenia, elevated LDH, increased ALT, neutropenia, increased AST, and elevated GGT. Common grade 3 or higher adverse events ( 〉 10%) were increased ALT (12 pts, 30%), increased AST (11 pts, 27.5%), neutropenia (6 pts, 15%) and elevated GGT (6 pts, 15%). Eight pts had 9 serious AEs (SAEs). The study is still ongoing and more data will be presented in the future. Conclusions: PFS benefit was observed in both 150mg and 200mg subgroups. This study demonstrated potentially improved efficacy with predictable toxicities of CM082 in combination with JS001 therapy, which may be an effective treatment option for pts with advanced mucosal melanoma.
