    Abstract: e21013 Background: The liver is one of the most common metastases in melanoma pts and associated with extremely poor prognosis. However, effective treatment has not been found. The safety and efficacy of OrienX010, a herpes simplex virus type 1-derived oncolytic immunotherapy with expression of gene encoding human GM-CSF, was tested in phaseⅠc trial of intralesional injection in liver metastases among patients with stage IV melanoma after standard treatment. Methods: We studied safety and efficacy of OrienX010 (8×10 7 pfu/ml, 10ml per injection) q2w by ultrasound guided puncture. Efficacy was evaluated q8w by CT scan. The primary endpoint was toxicity. Secondary endpoints included Objective Response Rate (ORR), Disease Control Rate (DCR) as well as PFS time. Treatment continued until intolerance, or disease progression per Immune Related Response Criteria. Results: From May 2016, 15 pts received OrienX010 intralesional therapy. The median age was 47 y (32, 61), and 53.3% were female. The primary anatomic sites were: 40.0% (6 pts) from ocular, 33.3% (5 pts) from acral, 26.7% (4 pts) from mucosal. Only 1 patient with c-Kit mutation, 14 pts were wide-type in genotype. All pts had received at least one prior therapy, 53.3% (8 pts) had received transcatheter hepatic arterial chemoembolization. 73.3% (11 pts) had multiple liver metastases, 60.0% (9 pts) had extrahepatic metastases such as lung, bone, abdominal, distant lymph node. 60.0% (9 pts) had an elevation of serum LDH. Mean injection times were 6 (4-18). Mean size of all injectable lesions was 30.4mm (10.0-59.0). AEs were all grade 1/2, pyrexia 80.0%, fatigue 33.3%, injection site pain 26.7%, nausea/vomiting 20.0%, hepatotoxicity 20.0%, leucopenia 6.7%. 12 pts were eligible for evaluation till Jan 2017, and the median follow-up time was 6.0 months. ORR was 8.3% (1 PR), DCR was 41.7% (1 PR, 4 SD). Time to response was 8-16 wks, median PFS was 13.3 wks (95%CI 8.3-18.4), OS was not reached. Conclusions: This is the first trial for evaluating OrienX010 of intralesional injection in liver metastases among melanomas. It appears to be tolerable and with a potentially beneficial effect. Phase 2 and combination trial are pending.

    Abstract: e21055 Background: Assessment of PD-L1 expression in tumor biopsy has been widely used for predicting anti-PD-1 therapy. Several factors, including tumor heterogeneity, false negative staining and unavailability of biopsy samples limit the application. Natural killer (NK) cells exert cytotoxicity against cancer cells. Therefore, we explored using NK cells percentage in peripheral blood (PB) as a biomarker to identify pts who are more likely to benefit from anti-PD-1 therapy. Methods: Pts treated with anti-PD-1 antibody (JS001) 1 mg/kg, 3mg/kg or 10mg/kg every 2 weeks in a Phase I clinical trial (ClinicalTrials.gov Identifier: NCT02836795) had PB collected at baseline and at time of radiographic evaluation performed every 8 wks. Disease status (shrinking stable disease, growing stable disease, partial response, complete response, or progressive disease) was characterized using RECIST v1.1 and immune-related response criteria. Frequencies of NK cells (CD3 - CD16 + CD56 + ) were measured by flow cytometry. Results: Thirty-six patients were enrolled in this trial, including 22 melanoma, 9 urothelial carcinoma and 5 renal cell carcinoma. As of 1/27/2017, median treatment duration: 3.92 months. Radiographic tumor evaluation has been performed in 32 pts: 1/32 CR, 6/32 PR, 6/ 32 shrinking SD, 4/32 growing SD and 15/32 PD. Pts with high NK cells at baseline observed 60% (6/10) Clinical Benefit Rate (CR/PR/ shrinking SD) versus 40% (13/32) in overall pts. Patients with clinical benefit had higher frequency of NK cells at baseline compared to pts with radiographic growing SD and PD (mean 24.3% vs. 17.9%, P = 0.076). Furthermore, pts with NK cell level consistently above UN or increasing above UN during treatment are more likely to get clinical benefit than those under UN (7/10 vs 3/22, P = 0.013). Conclusions: Baseline high NK cells frequency may predict a favorable response to anti-PD-1 therapy, which provides a non-invasive way to monitor response to PD-1 blockade. These results are being validated in a phase II trial. Clinical trial information: NCT02836795.

    Abstract: 3067 Background: JS001 blocks the interaction between PD-1 and its ligands and eradicates established tumor in human PD-1 Knock-in mouse model. Methods: A Phase I open-label study is designed to evaluate the safety and tolerability of JS001 in advanced solid tumor pts who are refractory to standard therapy. The study has a 3+3 dose escalation design with planned cohorts at 1, 3, and 10 mg/kg followed by a dose expansion. (Clinical Trial ID: NCT02836795). Results: As of January 27, 2017, pts enrollment has been completed with 36 pts from 3 indications (22 Melanoma; 9 Urothelial Carcinoma; 5 Renal Cell Carcinoma). The majority of melanomas are acral and mucosal origin. No DLT was observed and no MTD was reached in the study. The most common treatment-related AEs were grade 1/2, including hyper- or hypo-thyroidism (42%), rash (39%), fever (28%), leukopenia (22%), elevation of liver enzymes (19%), anorexia (17%), and fatigue (14%). Treatment–related grade 3 AEs include proteinuria (n = 1), and lipase increase (n = 2). The emergence of AEs is not dose related. JS001 PK shows dose-dependent exposure with the elimination half-life of 6 to 12 days. Among 32 evaluable pts, 1 pt have complete response (melanoma), 6 pts have partial response (3 melanoma, 2 RCC and 1 UC), and 10 pts achieve stable disease, for an ORR of 22% and a DCR of 53%. 6 out of 7 CR/PR pts still have ongoing response. Two groups of pts benefited most from JS001 treatment, pts with high tumor-infiltrating lymphocytes (TIL) (50% ORR) and pts with 〉 1% PD-L1 expression in tumor biopsy (46% ORR). Conclusions: JS001 exhibited a favorable safety profile in human. Treatment related AEs are in line with those from approved drugs in the same class. JS001 has demonstrated promising anti-tumor activity, especially in previously under-evaluated acral (20% ORR, 53% DCR) and mucosal (25% ORR, 50% DCR) melanomas. Clinical trial information: NCT02836795.

    Abstract: 9569 Background: Mucosal melanoma is rare and associated with extremely poor prognosis. Little is known about its outcome and prognostic analysis. In this study, we evaluated prognostic factors among mucosal melanomas. Methods: The survival rates, Relapse Free Survival (RFS), Overall Survival (OS) and prognostic factors were compared for 706 mucosal melanomas at different anatomical sites. Results: Mucosal melanoma from nasal pharyngeal and oral (268 pts), upper and lower gastrointestinal (GI) (221 pts), gynecological and urological (196 pts) had a similar survival with a 1-y survival rate (88%, 83%, 86%), 2-y survival rate (66%, 57%, 61%), 5-y survival rate (27%, 16%, 20%), respectively. Multivariate analysis revealed that Depth of Invasion (p 〈 0.001), Lymph node metastases (p 〈 0.001), Distant metastases (p 〈 0.001) were three independent prognostic factors for OS among 706 pts. Anatomical site (p = 0.031), Depth of Invasion (p 〈 0.001), Lymph node metastases (p 〈 0.001) were three independent prognostic factors for RFS among 543 pts. KPS status, Depth of Invasion, Lymph node metastases, Distant metastases were independent factors for OS among nasal pharyngeal and oral pts. Depth of Invasion, Lymph node metastases, CKIT Mutation were independent factors for RFS among nasal pharyngeal and oral pts. Gender, Lymph node metastases, Distant metastases were independent factors for OS among GI pts. Gender, Depth of Invasion, Lymph node metastases were independent factors for RFS among GI pts. Lymph node metastases, Distant metastases were independent factors for OS among Gynecological and Urological pts. Depth of Invasion, Lymph node metastases were independent factors for RFS among Gynecological and Urological pts. Conclusions: This is the first prognostic analysis for mucosal melanoma with the largest sample size for the first time. with few exceptions, It revealed that Depth of Invasion, Lymph node metastases, Distant metastases were independent prognostic factors for OS, Depth of Invasion and Lymph node metastases were independent prognostic factors for RFS. These results should be incorporated into the establishment of stage system and design of future clinical trials involving patients with mucosal melanoma.

    Abstract: 4575 Background: CM082 is an oral multikinase inhibitor targeting VEGFR, PDGFR and CSF1R with a shorter half-life and limited tissue accumulation, designed to lower toxicity and enable combination with other therapies. This is a phase I study to evaluate the safety, tolerability, pharmacokinetics, and preliminary efficacy of CM082 in combination with everolimus in patients with metastatic renal cell carcinoma. Methods: A 3+3 dose escalation design with expansion cohort was utilized to determine the dose-limiting toxicities (DLT) and the maximum tolerated dose (MTD) of CM082 plus everolimus at 5 mg PO daily for patients with metastatic clear cell renal cell carcinoma. Eligibility include PS 0-1, age ≥18 y, measurable disease, adequate organ function. Results: 22 patients (M/F: 16/6; median age: 55 y [range 32-69] ; 21/22 pts [95.5%] had received prior anti-VEGF treatment (tx); 2/22 pts [9.1%] had also received prior mTOR-targeted tx) were treated at 3 dose levels of CM082 (100 mg [n = 4]; 150 mg [n = 3] ; 200 mg [n = 15]) in combination with everolimus 5 mg. One patient in cohort 1 was not evaluable for DLT due to consent withdrawal. DLT were observed in one patient: G4 thrombocytopenia at 200 mg. CM082 200 mg plus everolimus 5 mg did not exceed MTD, but was chosen as the optimal biological dose regimen. Median duration of tx was 24 wk (range 1-57, 7/22 [32%] pts ongoing. The most common tx-related adverse events (AEs), all grades, were proteinuria 96% (G3, 5%); leukopenia 77% (G3, 9%); neutropenia 59%, hypercholesterolemia 64%, anemia 50% (G3, 9%), hypertension 46% (G3, 14%), raised aspartate aminotransferase 41%, fatigue 45%, diarrhea 32%, hypertriglyceridemia 32% (G3, 5%) and thrombocytopenia 20% (G4, 5%). At 200mg, partial response (PR) was observed in 5/14 (36%) patients, durable stable disease (SD) (≥24 week) or PR were achieved in 10/14 (71%) patients. Median PFS was 170 days (5.7 months) at this cohort. Conclusions: CM082 200mg in combination with everolimus 5 mg appeared to be well tolerated when administered to pretreated patients with advanced RCC in this Ph1 study. The preliminary efficacy warrant further evaluationand and the follow-up Ph 2/3 study is underway. Clinical trial information: NCT02577458.

    Abstract: e21017 Background: Vemurafenib has substantially impressive clinical efficacy in cutaneous melanoma (CM). However, compared with their cutaneous counterpart, acral melanoma (AM) and mucosal melanoma (MM) have distinct genetic patterns and worse prognosis. The efficacy and safety profiles of vemurafenib in AM and mm remain unclear. Methods: Clinical, pathological, and therapeutic data were collected and reviewed of patients (pts) with metastatic or unresectable BRAF-mutant AM and mm hospitalized and administrated vemurafenib during January 2011 and January 2017. Responses were evaluated by RECIST v1.1, survival data were analyzed by Kaplan-Meier survival curve, and adverse effects were assessed by CTCAE v4.0. Results: 24 pts were identified, 13 (54.2%) with AM, 11 (45.8%) with mm (1 patient without available radiology data). All 13 AM pts harbored BRAF V600E mutation (1 with simultaneous C-KIT E861K mutation); 10/11 (90.9%) mm pts carried BRAF V600E mutation (1 with simultaneous PDGFRA V824I mutation), 1/11 (9.1%) had BRAF D594N mutation. Median PFS were 5.4 (95%CI 3.5-8.7) and 4.5 (95%CI 1.5-15.0) months, median OS were 11.7 (95%CI 8.1-23.6) and 7.9 (95%CI 4.6-26.2) months; ORRs were 61.5% (8/13) and 40.0% (4/10), DCRs were 92.3% (12/13) and 90.0% (9/10) in AM and MM, respectively. Vemurafenib was well tolerated. The most common adverse effects (AEs) were hand-foot syndrome in AM and elevation of total cholesterol in MM, with the incidence of 23.1% (3/13) and 18.2% (2/11), respectively. Grade 3/4 AEs have not been observed. No patient discontinued vemurafenib because of treatment related toxicity. Conclusions: Vemurafenib yields substantial response in pts with AM and MM. Compared with in CM, vemurafenib has similar efficacy and safety profiles in BRAF-mutant AM and MM.

    Abstract: e20027 Background: Imatinib, a selective inhibitor targeting Abl as well as C-Kit and the platelet-derived growth factor receptor, has been tested for the efficacy and toxicities in metastatic melanoma patients harboring mutations in C-Kit gene. High-dose interferon for one year (HDI) is the FDA approved adjuvant therapy for patients (pts) with high-risk melanoma. This study (NCT01782508) aims to see whether imatinib is more effective than interferon alfa-2b in adjuvant therapy for patients with C-Kit mutated melanomas. Methods: This study enrolled C-Kit mutated(exon 9,11 or 13)pts who were high risk (stage IIB to stage IIIC) and randomized them to receive either imatinib (400mg daily for a year) or HDI (interferon a-2b 15X10 6 U/m 2 d 1–5 /wX4w + 9X10 6 U tiwX48w) in the absence of disease progression or unacceptable toxicity. 40 pts of each group were planned to enroll. Routine tests including blood tests, medical history updates, physical exams and Brain/Chest/Abdomen/Pelvic CT were performed every 2 months. The endpoints were recurrence-free survival (RFS) and overall survival. Results: Through Jan 2013,7 pts were recruited F3 in imatinib arm and 4 in HDI arm. The three pts received imatinib haven’t had recurrence or metastasis. The RFS were 6m+ (Exon 11: W577S), 5m+ (Exon 11: L576P), 5m+ (Exon 11: L576P) respectively. Two pts have already had lung or regional lymphnode at 4 months (Exon 13: K642E) and 5 months (Exon 11: V560D) in the HDI arm. The other two pts (both Exon 11: 579 insert) in the HDI arm were still disease free for 6 months. The toxicities were consistent with the usual reported studies. Conclusions: In the C-Kit mutated melanoma pts, it’s promising that imatinib may provide more beneficial effect than HDI for high-risk melanomas.

    Abstract: e15051 Background: Recent evidences have indicated that hypertension and obesity predict longer PFS of targeted therapy in metastatic renal cell carcinoma (mRCC) patients, thus we suppose polymorphisms in hypertension associated genes(angiotensinogen, AGT; vascular endothelial growth factor, VEGF) and obesity associated gene (apolipoprotein E, APOE) may have an effect on treatment outcome in patients treated with targeted therapy for mRCC. Methods: A cohort of consecutive patients (pts) treated with sunitinib or sorafenib were studied. Baseline clinical characters such as age, gender, blood pressure and BMI (body mass index) were recorded. All patients were genotyped for genetic polymorphisms in rs2493137 of AGT, rs699947 of VEGF and rs8106922, rs405509 of APOE from peripheral blood. All the patients were followed up for progression free survival(PFS),overall survival (OS),objective response rate (RR). Results: We studied a cohort of 77 cases, 58 (24.7%) pts were male, 18 (23.4%) pts were ≥65 years and 47 (61%) pts received sunitinib. The distribution of all the tested SNP genotypes were in Hardy-Weinberg equilibrium (p 〉 0·05). With a median follow-up time of 24 months (range: 1.5-36.2 months), 60 pts developed progression and 34 pts died. The rs2493137 TT genotype in the AGT gene showed a trend of prolonging PFS when compared with the CC+CT genotypes, but without statistically significance (p=0.08). No correlations were found among other genotype subgroups (rs699947, rs8106922 and rs405509) on either clinical characters or survival endpoints in this study. Conclusions: Polymorphism in the promoter of AGT gene (rs2493137) might be associated with better clinical outcome in patients treated with targeted therapy for mRCC. Further studies with a larger sample size are needed on the function of this polymorphism.
