    Abstract: 9550 Background: Acral and mucosal melanoma were rarely seen in Caucasians but common in Asians. Previous studies revealed that acral and mucosal melanoma are more aggressive than cutaneous melanoma with a high unmet need for effective treatments. Camrelizumab plus anti-angiogenic agents have shown promising antitumor activity in previously untreated melanoma. Famitinib, a selective multiple-target tyrosine kinase inhibitor that exhibits both anti-angiogenesis and antiproliferative effects via targeting VEGFR-2, PDGFR, c-kit, FGFR and so on, combined with camrelizumab had been proven effective in multiple cancers. This study aimed to assess the antitumor activity and safety of camrelizumab plus famitinib in both immunotherapy naïve and experienced advanced mucosal or acral melanoma. Methods: This single-center, open-label phase II study recruited patients (pts) with advanced acral and mucosal melanoma. Pts who were immune checkpoint inhibitors (ICI) treatment naïve were in cohort 1, while pts experienced ICI in cohort 2. In both cohorts, pts received camrelizumab (200 mg i.v. q3w) and famitinib (20 mg po qd) until disease progression or intolerable toxicity. The primary endpoint was objective response rate (ORR) per RECIST1.1. Secondary endpoints included progression free survival (PFS), disease control rate (DCR), overall survival (OS), and safety. This analysis focused on cohort 2. Results: As of January 12, 2023, 18 pts (9 mucosal and 9 acral histology subtypes) were enrolled in cohort 2. The median age of all pts was 58 yrs (ranged 38-71 yrs); 9 pts (50.0%) were female; prevalence of mutations: BRAF (11.1%), C-KIT or NRAS (16.7% each); 38.9% received ≥2 prior treatments. All pts progressed after anti-PD-1/L1 monotherapy (27.8%) or combinational therapy (66.7%), except one progressed after 4-1BB mAb monotherapy. The combination drugs included anti-LAG-3/CTLA-4 antibodies (38.9%), oncolytic viruses (11.1%), c-kit inhibitors, chemotherapy and anti-angiogenic agents (5.6% each). The median follow-up was 7.3 months (ranged 4.6-14.7 months). At the data cutoff, 5 pts remained on treatment. 17 pts were evaluable. The ORR and DCR were 17.6% and 64.7%, including two pts with confirmed PR, and one with unconfirmed PR, all of which were acral subtype. The median PFS was 6.0 months. The median OS was not reached. Of 18 pts, the incidence of treatment-related adverse events (TRAEs) was 88.9%. The most common grade 3 TRAEs was neutrophil count decreased (11.1%). No grade 4 TRAEs and no treatment-related deaths occurred. Conclusions: Camrelizumab plus famitinib showed promising antitumor activity in ICI-experienced advanced acral and mucosal melanoma pts, and was generally well tolerated. Clinical trial information: NCT05051865 .

    Abstract: 9530 Background: CD137 plays the roles as a potent co-stimulator of both adaptive and innate immune cells, being an attractive target for cancer immunotherapy. TWP-101 is a fully humanized agonistic anti-CD137 monoclonal IgG4 antibody, targeting a novel epitope of CD137 with a unique mechanism of actions as a CD137 agonist but not CD137 ligand antagonist. The phase I study of TWP-101 in patient (pt)s with advanced melanoma and urothelial carcinoma was initiated (NCT04871334). Methods: Enrolled pts were advanced melanoma refractory to standard therapy. Dose-escalation includes accelerated titration (0.01 and 0.03mg/kg) and conventional Fibonacci 3+3 dose levels (0.1, 0.3, 1.0 and 3.0 mg/kg). TWP-101 was administered intravenously every Q2W until confirmed progressive disease, unacceptable toxicity or withdrawal of consent. The primary objectives were to define the safety profile, to determine the maximum tolerated dose and RP2D of TWP-101. Secondary objectives were to evaluate pharmacokinetics (PK), immunogenicity and preliminary clinical efficacy. Exploratory objectives were to determine pharmacodynamics (PD) biomarkers. Results: From Feb 2021 to Mar 2022,13 melanoma pts (median age 54 years, range 39-73; 6 men, 7 women; median 2 prior lines of therapy, range 1-6; 12 with prior immunotherapy) were treated. The following five dose levels had been evaluated from 0.01 to 1.0 mg/kg. 3mg/kg dose escalation is ongoing, no MTD has been reached. The median treatment time was 16 wks. (range 2-59). On cutoff date of October 31, 2022, 13 pts discontinued treatment due to progression disease (n = 12) and protocol deviation (n = 1). No DLTs were observed. 9 pts (69.2%) experienced treatment-related adverse events (TRAE). The most common TRAEs (≥10%) were neutropenia (23.1%), leukopenia (15.4%), hypertriglyceridemia (15.4%), anemia (15.4%), hyponatremia (15.4%). 1 pt experienced grade 3-4 TRAEs: hyponatremia, Asthenia and reduced appetite. In all TRAEs, one grade 1 decreased free triiodothyronine and one grade 2 pyrexia were possibly related, and all other TRAEs, including 2 treatment-related SAEs (1 grade 4 hyponatremia and 1 grade 2 subarachnoid hemorrhage), were identified as possibly unrelated. Deaths were due to progression disease (n = 3). Preliminary PK analysis showed dose-proportional kinetics. For 12 evaluable pts, 2 pts achieved PR (16.7%), 5 pts was SD. DCR was 58.3%. Median PFS was 16 wks. (range 16-60), PFS of 2 PR pts was 24 and 60 wks. Conclusions: TWP-101 demonstrated a good safety profile without hepatotoxicity frequently observed with other studied CD137 antibodies. Both favorable tolerability and preliminary antitumor activity warrant further evaluation in pts with advanced melanoma and urothelial carcinoma. Clinical trial information: NCT04871334 .

    Abstract: 9512 Background: A phase IB trial had showen promising antitumor activity with toripalimab (T, a PD-1 antibody) plus axitinib (A, a VEGF receptor inhibitor) in treatment-naive unresectable or metastatic mucosal melanoma. Now we conducted a phase II trial to compare the combined treatment with monotherapy. Methods: In this randomized, controlled, phase II trial, patients with pathologically confirmed treatment-naive unresectable or metastatic mucosal melanoma were stratified by PD-L1 expression and randomized 1:1:1 into three groups to receive treatment of T+A (toripalimab 240 mg i.v. every 3 weeks, axitinib 5 mg orally twice a day), T (toripalimab 240 mg i.v. every 3 weeks) or A (axitinib 5 mg orally twice a day). Subjects in T or A who meet the criteria after disease progression may cross over to receive T+A. The primary endpoint was progression-free survival (PFS). Secondary endpoints included Objective response rate (ORR), Duration of response (DOR), overall survival (OS), and safety. The protocol was registered at ClinicalTrials.gov (NCT03941795). This is the interim analysis for efficacy and safety. Results: Between Nov 2019 and Jan 2022, 51 patients were randomized (18 to T+A, 20 to T, and 13 to A due to preliminary efficacy analysis). Anatomic site of head and neck, gastrointestinal, gynecological were 49.0%, 29.4%, 21.6%, respectively. Stage II or III unresectable, M1a, M1b, M1c were 3.9%, 23.5%, 17.6%, 51.0%, respectively. PD-L1 positivity was defined as ≥1% of tumor cells and/or infiltrating immune cells and were identified in 55.6%, 45.0%, 53.8% patients in T+A, T, A group, respectively. 17, 17 and 12 patients could be evaluated in T+A, T and A group, respectively. 24 patients from T or A crossover to T+A group. At a median follow-up of 6.60 months, patients receiving T+A had a higher median PFS (5.83 vs 2.80 vs 1.40 months; HR = 0.538; 95% CI, 0.237 to 1.221; HR = 0.444; 95% CI, 0.182 to 1.081; P = 0.170), ORR (35.3% (29.7% if including crossover patients ) vs 17.6% vs 8.3%), DOR (82.4% (70.3% if including crossover patients) vs 52.9% vs 58.3%) versus T or A group. The median OS was not reached. 80.4% 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, elevated transaminase, elevated bilirubin, hypertension, hypo- or hyperthyroidism, and rash. Grade 3 or greater TRAEs occurred in 33.3%, 30.0%, 30.8% of patients in T+A, T, A groups. Conclusions: Toripalimab plus axitinib showed promising antitumor activity versus toripalimab or axitinib alone in patients with treatment-naive unresectable or metastatic mucosal melanoma. Clinical trial information: NCT03941795.

    Abstract: 9508 Background: PD-1 monotherapy as the first line stand treatment for advanced melanoma yields an objective response rate (ORR) of 〈 20% in AM. Although multiple clinical trials are ongoing testing TMZ/APA, TMZ/PD-1 and APA/PD-1 combo therapies in AM, the reported ORR (range 17-23.8%) are far from satisfactory. We therefore conducted a phase II study of CAM/APA/TMZ combo in this subtype aiming for improved efficacy. Methods: We performed a single center, single arm phase II study (NCT04397770) testing the efficacy and safety of CAM/APA/TMZ combo as first-line therapy in pts with advanced AM. The primary endpoint was ORR per RECIST1.1, secondary endpoints included progression free survival (PFS), disease control rate (DCR), overall survival (OS), and safety. All pts received iv CAM (200mg q2w), iv TMZ (200mg/m2 d1-5, q4w) and po APA (250mg qd) until disease progression or intolerable toxicity. Results: By Jan 2022, fifty pts were enrolled (48 evaluable), the median follow-up was 12.1 mo (IQR 8.4-14.5). Thirty-one pts achieved CR/PR as the best response (including 1 CR and 30 PR), the ORR was 64.6% (95% CI 49.4-77.4%). The DCR was 95.8% (95%CI, 84.6-99.3%). Both the median PFS and OS was not reached (NR); 6-mo and 12-mo PFS rate was 81.7% (95%CI 71.6-93.3%) and 62.9% (95%CI 48.4-81.7%), respectively; 12-mo OS rate was 82.3% (95%CI 68.2-99.2%). The incidence of treatment-related adverse events (TRAEs) was 94% (47/50). Of 50 patients, the most common grade ≥3 TRAEs included γ-glutamyl transferase elevation (24.0%), direct bilirubin elevation (22.0%), aspartase transaminase elevation (20.0%), alanine transaminase elevation (16.0%), and hypertriglyceridemia (14.0%). No treatment-related deaths occurred. Conclusions: The CAM/APA/TMZ combination demonstrated promising efficacy as the first-line treatment for pts with advanced AM, and was generally well tolerated. Phase III randomized control trial is warranted. Clinical trial information: NCT04397770.

    Abstract: 4566 Background: Disitamab vedotin has shown promising data across a spectrum of HER2 expression in patients with locally advanced or metastatic urothelial carcinoma (la/mUC) who progressed on chemotherapy. This study was conducted to evaluate the safety and efficacy of disitamab vedotin plus anti-PD-1 antibody in advanced urothelial carcinoma. Methods: This is an open-label, multicenter, phase 1b/2 trial to evaluate the safety and activity of RC48-ADC combined with toripalimab, a humanized immunoglobin G 4 monoclonal antibody against PD-1 in mUC. Patients received RC48-ADC at 1.5 or 2 mg/kg, in combination with 3mg/kg toripalimab every two weeks in a dose-escalation and expansion cohort until confirmed disease progression assessed by the investigators, unacceptable toxicity, or voluntary withdrawal. The primary endpoint was safety; secondary endpoints included efficacy and tumor tissue biomarkers. Results: Forty-one la/mUC patients were enrolled (22 males; median age 66 y [42-76]; 61% treatment-naïve). 54% of patients had visceral metastases (mets), including 24% with liver mets. The primary site was in upper tract UC in 54%. HER2 expression IHC 2+ or 3+ was in 59% patients, and PD-L1 positive in 32%. No dose-limiting toxicity was observed and the recommended dose was RC48-ADC 2mg/kg plus toripalimab 3mg/kg every two weeks. By the cutoff date of 18 November 2022, the confirmed ORR was 73.2% (95%CI: 57.1, 85.8), including 9.8% CR. The ORR was 76.0% for treatment-naïve patients. In HER2 IHC 3+/2+, IHC 1+, and IHC 0 subgroups, the ORR was 83.3%, 64.3%, and 33.3%, respectively. The ORR was 61.5% and 78.6% in PD-L1 positive and negative subgroups. DCR was 90.2% (95% CI, 76.9–97.3), with a median progression-free survival (PFS) of 9.2 months (95%CI: 5.7-10.3) and 2-year overall survival (OS) rate of 63.2%. All patients experienced treatment-related adverse events (TRAEs). The most common TRAEs were AST/ALT increase (68.3%), peripheral sensory neuropathy (61.0%), asthenia (61.0%), γ-glutamyl transferase increase (56.1%), hypertriglyceridemia (53.7%), and appetite decrease (51.2%). Grade 3 or greater TRAEs occurred in 43.9% of patients. Twenty-three patients (56.1%) had immune-related AEs (14.6% ≥ G3), including immune-related skin reactions, hyperglycemia, pneumonitis, hepatitis, and myositis. Conclusions: RC48-ADC in combination with toripalimab demonstrated promising efficacy in patients with la/mUC and a manageable safety profile. A phase 3 study is currently ongoing to compare the safety and efficacy of this regimen with standard of care. Clinical trial information: NCT04264936 .

    Abstract: 9564 Background: Advanced melanoma with liver metastasis has a lower response rate and survival even in immunotherapy era which might because of its immunosuppressive tumor microenvironment. CPI combined with TVEC had showed a remarkable in cutaneous melanoma. The initial results of the phase 1b trial, systemic toripalimab (anti-programmed cell death-1 antibody) combined with Intratumoral injection of liver with OrienX010 - a HSV-1-derived oncolytic virotherapy with expression of GM-CSF in liver metastasis patients without extra-hepatic injectable lesions had shown its efficacy. Here we present the PFS and overall survival (OS) outcomes. 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 toripalimab Q2W combined with ultrasound guided intratumoral injection of OrienX010 Q2W (8×10 7 pfu/ml, 10ml per injection) until intolerance or disease progression per iRECIST criteria. Liver biopsy would be performed at baseline and first tumor evaluation (8-12weeks). The primary endpoint was toxicity; secondary endpoints included ORR, disease control rate (DCR), PFS and OS. NCT04206358. Results: From Jul 2019 to Feb 2023, 30 pts enrolled. 60.0% pts primary from mucosal,; 73.3% got extra-hepatic metastasis; median size of injected lesions: 24mm(10-94mm); median number of liver metastasis: 7(1-10); median number of injection: 10 (3-36). Among these pts, 29 pts could be evaluated for efficacy. The median PFS was 7.0months (95%CI: 4.7-9.3 months) and the median OS was not reached. The 3-year OS rates 51.5%. The global ORR by investigator was 20.7% (6/29), DCR 48.3% (14/29); the response rate was 31.0%(9/29) for injected lesions, 30.0%(6/20) for non-injected lesions in liver, and 27.8% (5/18) for extra-hepatic metastases. For pts（21.7%( 2 PR and 3 SD)）with no melanoma cells residual by immunohistochemistry in biopsies the median PFS was 14.0 months (95%CI: 3.7-24.4 months), and it was much longer than that of other pts which was 4.1 months (95%CI: 1.4-6.8 months). The median OS of the pts with no melanoma cells was 19.7 months (95%CI: 7.5-31.9 months). Most adverse events (AE) were grade 1-2 and manageable. The grade 3-4 treatment-related AE included elevated transaminase (3 [10.0%]), nausea (1 [3.3%] ), pulmonary embolism (1 [3.3%]) and vomiting (1 [3.3%] ). No treatment-related deaths occurred. Conclusions: Systemic toripalimab combined with intrahepatic OrienX010 injection has shown remarkable long PFS, OS and ORR in melanoma pts with liver metastases with manageable toxicity.

    Abstract: e21543 Background: Acral melanoma, the most common subtype of cutaneous malignant melanoma in Asians, is often diagnosed at an advanced stage but responds poorly to current PD-1/PD-L1 inhibitors. Here, we report an open-label, multicenter, single-arm, phase Ib study, aiming to evaluate the safety and efficacy of the combination therapy of TQB2450, a humanized monoclonal antibody against PD-L1 and anlotinib, an anti-angiogenic oral multi-target tyrosine kinase inhibitor in patients with advanced acral melanoma. Methods: Eligible patients were adults (ECOG PS of 0 or 1) with pathologically confirmed metastatic acral melanoma. In this dose-escalation and cohort-expansion study, patients received TQB2450 1200mg every 3 weeks in combination with anlotinib 10mg or 12mg once daily, 2-week on/1-week off until conformed disease progression, unacceptable toxicity, or voluntary withdrawal. The primary end points were dose-limiting toxicity (DLT), maximum tolerated dose (MTD) and objective response rate (ORR). The secondary end points included adverse events, disease control rate (DCR), progression-free survival (PFS), overall survival (OS). Results: By December 8, 2021, 19 patients has been enrolled. The majority of patients (16 of 19 patients) were naive to systemic therapy. No DLT was observed. Eighteen (95%) of 19 patients experienced treatment-related adverse events (TRAEs), but most were grade 1 or 2. The most common TRAEs were hypothyroidism, hypertension, blood triglyceride elevation, hyperglycemia, blood cholesterol elevation, neutropenia, blood uric acid elevation, bilirubin elevation. Grade 3 or greater TRAEs occurred in 6 patients (31.6%). Among all patients with advanced acral melanoma assessed by investigator according to RECIST version 1.1, two patients achieved confirmed complete response and two patients achieved confirmed partial response. The ORR were 21.1% (95% CI, 6.1% to 45.6%). The DCR was 73.7% (95% CI, 48.8% to 90.9%). The median PFS time was 5.5 months (95% CI, 2.8 months to not reached) per RECIST version 1.1. The median OS was 20.3 months (95% CI, 10.2 months to not reached). Conclusions: The combination of TQB2450 plus anlotinib showed promising benefit and was tolerable in patients with advanced acral melanoma, which needed further investigation of the combination therapy in advanced acral melanoma. Clinical trial information: NCT03991975.

    Abstract: 9514 Background: Combination therapy of anti-PD1 agent with VEGFR inhibitor is a promising therapeutic approach in unresectable or metastatic mucosal melanoma. We conducted this study evaluating neoadjuvant lenvatinib and pembrolizumab in pts with resectable mucosal melanoma. Methods: This was a single-arm, open-label, single-center, ongoing phase 2 study conducted from Sep 2021. Eligible pts were adults (18-75 yr) with histologically confirmed, resectable mucosal melanoma. Pts received lenvatinib 20mg qd and pembrolizumab 200mg q3w for 2 cycles, followed by surgery. Pembrolizumab (200mg q3w) continued post operatively for further 15 cycles. The primary endpoint was complete pathologic response (pCR). Secondary endpoints were Event free survival (EFS), Overall survival (OS) and safety. Results: As of Dec 2022, 19 pts were enrolled with a median follow-up of 49 wks (95%CI, 38 -60). Median age was 57 yrs, 14 were female. Primary sites included: 8 female genital, 6 ano-rectal, 4 head & neck (1 nasal, 3 oral),1 esophageal. 12 pts were localized disease,7(37%) were regional lymphatic disease. KIT or NRAS mutations were presented in 2 and 3 pts, respectively. 15 pts underwent surgery, 2 pts had a pCR (13.3 %), 1 MPR, 3 pPR, with a pathologic response rate of 40%(6/15,95%CI 16-67%). 4 pts did not proceed with planned surgery for pts preference. Median EFS has not been reached. IHC data of the resected tumor showed higher CD8+ T cells density in responders (R=pCR+ MPR + pPR) than non-responders (NR=pNR) (p = 0.04). In 6 pts(one pPR and 5pNR) with paired pre and post treatment samples, CD3+ and CD8+ T cells were significantly increased following treatment (p =0.03). Most common AEs were proteinuria (6, 32%), hypothyroidism (6, 32%), dysphonia (5, 26%). One pt(5%, 1/19) had grade 3 ALT elevation. No grade 4-5 toxicities were observed. Conclusions: The combination of pembrolizumab plus lenvatinib as neoadjuvant therapy in resectable MM is safe. The preliminary data has shown promising pathologic response with increased CD8+ T cell infiltration, supporting further investigation of neoadjuvant treatment in MM.

    Abstract: 4519 Background: RC48-ADC is a novel humanized anti-HER2 antibody-drug conjugate (ADC). A phase II clinical study showed that RC48-ADC has a good effect on locally advanced or metastatic urothelial carcinoma with HER2-positive expression that failed standard chemotherapy. In the study, some patients with HER2-postive immunohistochemistry (IHC 2+) but negative FISH test still benefited from the treatment of RC48-ADC.This study was to evaluate the activity and safety of RC48-ADC in HER2-negative patients with locally advanced or metastatic urothelial carcinoma. Methods: This study is an open-label, single-center, single-arm, phase II trial. Eligibility criteria include: histologically confirmed urothelial carcinoma, HER2-negasitive (IHC 0 or 1+), ECOG PS 0-1,and treated with ≥1 prior systemic treatment. Patients received RC48-ADC 2mg/kg q2w until disease progression, unacceptable toxicity, withdrawal of consent, or study termination. The primary objectives were activity (ORR) and safety. Second objectives included progress-free survival, disease control rate and overall survival. Results: As of February 2022(date cutoff),19 patients were enrolled. The median age was 64 years old(range:36-77). At baseline, there were 6 patients with HER2(IHC 0), and 13 patients with HER2(IHC 1+).Most patients (13/19) had visceral metastasis. 15(79%) patients had received≥2 lines treatment.At date cutoff, 19 patients were assessable for response. The objective response rate was 26.3% (95% CI:9.1%,51.2%) and the DCR was 94.7% (18/19). The mPFS was 5.5months (95% CI:3.9,6.8) and mOS was 16.4months (95% CI:7.1,21.7).All of the 6 patients with HER2(0) were SD in the study. The ORRs were 38% (5/13) in patients with HER2(IHC 1+),31% (4/13) in visceral metastasis,17% (1/6) in liver metastasis patients,27% (4/15) in patients post to ≥ 2 lines of treatment. Common treatment-related AEs were leukopenia (52.6%), hypoesthesia (47.4%),alopecia (47.4%), AST increase (42.1%), ALT increase (42.1%), and neutropenia (42.1%), fatigue (42.1%),nausea (26.3%), vomiting (15.8%).Most of these AEs were Grade 1 or 2. The AE of Grade 3 was neutropenia (10.5%). The SAE was CPK increased (5.3%). Conclusions: This study showed that RC48-ADC was safe and the ORR was 26.3% in HER-negative patients with locally advanced or metastatic urothelial carcinoma. The enrollment was completed and data will be updated later. Clinical trial information: NCT04073602.

    Abstract: 9508 Background: Chemotherapy (temozolomide plus cisplatin) has been demonstrated to be a better adjuvant regimen compared to high-dose interferon alpha-2b in resected Mucosal Melanoma (MuM) in the pre-immunotherapy era. Yet in the present immunotherapy era, PD-1 inhibitor was recommended as a standard adjuvant therapy for resected Melanoma. No adjuvant trial comparing chemotherapy with PD-1 inhibitor in resected MuM had been reported. we conducted this study to determine the efficacies of adjuvant chemotherapy versus PD-1 inhibitor in resected MuM. Methods: All patients (pts) with resected MuM received chemotherapy (temozolomide 200 mg/m 2 /day orally on days 1 to 5 plus cisplatin 75 mg/m 2 i.v. on days 1-3, repeated every 3 weeks for six cycles) or Toripalimab (anti-PD-1, 3 mg/kg every 2 weeks via intravenous infusion) as adjuvant therapy from 2013 to 2019 were included retrospectively. Demographic and clinical characteristics between the two groups were matched with 1:1 by propensity score matching (PSM) to reduce the bias. After PSM, the efficacies of the two groups were compared, and subgroup analysis was performed according to the baseline characteristics. The endpoints were relapse-free survival (RFS), distant metastasis-free survival (DMFS), and overall survival (OS). Kaplan-Meier methods and Cox regressions were used to estimate median RFS, DMFS, OS and HR. Results: A total of 247 pts were included, of which 78 were in the Toripalimab group and 169 were in the Chemo group. PSM matched 65 pts from each of the two groups. The baseline characteristics were similar. At a median follow-up of 52.6 months (95%CI, 44.6-60.6 months), patients receiving chemo had a longer median RFS (28.2 vs. 12.0 months; HR=0.64, 95% CI, 0.42 to 0.98; P=0.04), DMFS (42.0 vs. 19.0 months; HR=0.58, 95% CI, 0.36 to 0.92; P=0.02) and OS (93.4 vs. 39.3 months; HR=0.56, 95% CI, 0.33 to 0.94; P=0.03) versus the toripalimab group (Table). Conclusions: Adjuvant chemotherapy (temozolomide plus cisplatin) shows remarkable longer RFS, DMFS, and OS than Toripalimab (anti-PD-1). It suggested that adjuvant chemotherapy may be a better option for patients with resected mucosal melanoma even in the present immunotherapy era. [Table: see text]
