Abstract Background: Prognosis of patients with metastatic malignant melanoma is very poor and partly due to high resistance to conventional chemotherapies. The study’s objectives were to assess the activity and tolerability of apatinib, an oral small molecule anti-angiogenesis inhibitor, in patients with recurrent advanced melanoma.Methods: This was a single-arm, single-center phase II trial. The primary endpoint was progression-free survival (PFS) and the secondary endpoints were objective response rate (ORR), disease control rate (DCR), and overall survival (OS). Eligible patients received at least one first-line therapy for advanced melanoma and experienced recurrence. Apatinib (500 mg) was orally administered daily. Trail registration: Clinical Trials, ID: NCT03383237. Registered on 24 December 2017. URL of trail registry record: https://register.clinicaltrials.gov. Results: Fifteen patients were included in the analysis. The median PFS was 4.0 months. There were two major objective responses, for a 13.33% response rate. Eleven patients had stable disease, with a DCR of 86.67%.The median OS was 12.0 months. The most common clinically significant grade 3 or 4 toxicities included hypertension and canker sore. No treatment-related deaths occurred.Conclusions: Apatinib showed antitumor activity as a second or first-line therapy in patients with malignant melanoma. The toxicity was manageable.

e22026 Background: The prognosis of patients with metastatic malignant melanoma is very poor, a fact that is partly due to its high resistance to conventional chemotherapies. The objectives of this phase II trial were to assess the activity and tolerability of apatinib, an oral small molecule anti-angiogenesis inhibitor, in patients with recurrent advanced melanoma. Methods: This was a single arm, single center phase II trial. The primary endpoint was progression free survival (PFS), and the second endpoints was objective response rate (ORR), disease control rate (DCR) and overall survival (OS). Eligible patients received at least one prior line of therapy for advanced melanoma and experienced recurrence. Apatinib was given daily at a dose of 500 mg orally. This study was registered at ClinicalTrials.gov , number NCT03383237 . Results: A total of 17 patients were included in the final analysis. The median PFS was 4.5 months. There were two major objective responses, for a response rate of 11.8%. Thirteen patients had a stable disease, for a DCR of 88.2%. The median OS was 11.5 months. The most common clinically significant grade 3 or 4 toxicities included hypertension (n = 1) and canker sore (n = 1). No treatment-related death occurred. Conclusions: Apatinib showed antitumor activity as a second or above line therapy in patients with malignant melanoma. The toxicity was manageable. Clinical trial information: NCT03383237.

The Impact

9049 Background: Correlations between overall survival (OS) and objective response rate (ORR) or progression-free survival (PFS) are poor. We aimed to evaluate the impact of crossover and unbalanced subsequent treatments on ORR and PFS as surrogate endpoints for OS in patients with advanced NSCLC receiving first-line therapy. Methods: A systematic literature review of randomized clinical trials of systemic treatment for patients with stage IIIB/IV NSCLC receiving first-line therapy was performed. Weighted (by trial size) linear regression models were fitted with the absolute difference in ORR or median PFS as an independent variable and the absolute difference in median OS as a dependent variable. The analysis was repeated in predefined subsets based on crossover and balance of post-progression therapies. Surrogate threshold effect (STE) was estimated using prediction intervals. Results: 317 trials (78,644 patients) fulfilled the eligibility criteria. In all treatment arms, the mean ORR, median PFS, and median OS were 28.2% (standard deviation (SD) = 12.4%), 5.1 months (SD = 2.1), and 10.4 months (SD = 2.5), respectively. ORR and PFS had weak (R = 0.351; 95% CI: 0.251-0.443) and (R = 0.397; 95% CI: 0.267-0.512) associations with OS, respectively. However, within phase III trials that did not allow crossover and reported balanced post-progression treatments, both ORR and PFS had stronger associations with OS (ORR and OS: R = 0.601, 95% CI: 0.399-0.747; PFS and OS: R = 0.695, 95% CI: 0.446-0.844). STE estimation indicated that trials that show statistically significant treatment effect size of ≥43% ORR or ≥3.2 median PFS months can be expected to show significant OS benefit with sufficient certainty. Conclusions: Surrogacy of ORR and PFS for OS might be better estimated in trials that do not allow crossover and report balanced post-progression treatments. Presented STE calculation can be used to estimate the expected effect on OS when either ORR or PFS are used as primary endpoints.

Ras Status

438 Background: Personalized medicine is a challenge for current oncology practice. Nowadays there are no pharmacoeconomic analyses in Spain dealing with the clinical and financial impact secondary to K-Ras based decisions for first-line therapy in mCRC patients. So, this study was aimed to assess the cost- effectiveness of K-Ras status based decisions in first- line therapy of mCRC patients in comparison with non- K-Ras based selection of available therapies. Methods: K-Ras mutation prevalence and efficacy of available therapies (measured as response rate and progression free survival) were extracted from randomized clinical trials (RCT) that allowed on-label use of accessible drugs in Spain. Then, we have simulated all possibilities of combination therapies for first-line mCRC based on K-Ras status (wild- type vs mutated) and confronted with all therapies that could be chosen in absence of K-Ras analysis. Prices for all drugs in Spain were used to assume the best- value for each drug including all possibilities to reduce pharmacy costs. For first line, median duration of therapy reported by RCT was used to calculate the final budget. 70 kg and 1.7 m were used as reference for patients dose calculations. Results: First-line therapy that includes a biological drug in absence of K-Ras status based decisions implies an incremental cost per 1% of increased response rate of 1,237 euros for irinotecan based doublets and 3,193 euros for oxaliplatin based doublets. On the opposite, K-Ras based decisions reduce costs per objective response by 69% and 35% for irinotecan and oxaliplatin- based schedules in K-Ras wild-type population incorporating cetuximab as biological agent. These data mimic all calculi based on incremental costs secondary to improved progression free survival measured as HR when all scenarios without prior determination of K-Ras status were confronted with K-Ras based decisions. Conclusions: K-Ras based decisions reduces costs per objective response as well as per improved progression free survival. The most cost- effective scenario among all simulated was cetuximab in combination with chemotherapy for patients that harbor wt K-Ras mCRC.

The Status

566 Background: The Asia-Pacific, multicenter, nonrandomized, phase II APEC study previously reported that first-line therapy for pts with KRAS ex 2 wt mCRC consisting of C once every 2 weeks combined with FOLFOX or FOLFIRI achieved efficacy and safety profiles comparable to those reported in analogous pivotal studies involving weekly C. This final analysis presents OS data from the KRAS wt intent-to-treat (ITT) population, as well as subgroup efficacy analyses stratified by BRAF, PIKC3A, and all RAS mutation status. Methods: Eligible pts received C once every 2 weeks (day 1 of each cycle, 500 mg/m2) with FOLFOX or FOLFIRI (investigator’s choice). Study treatment continued until disease progression, dose-limiting toxicity or consent withdrawal. The primary endpoint was best confirmed overall response as assessed by RECIST 1.0; progression-free survival (PFS) and OS were secondary endpoints. In the evaluable populations, the status of BRAF, PIK3CA, and all RAS mutations was assessed retrospectively by pyrosequencing. Results: 42 months after the last patient was enrolled, median OS in the KRAS wt population was 26.8 months (Table). There were no unexpected safety findings. Additional biomarker results—including objective response rate (ORR), PFS, and OS subgroup analyses stratified on BRAF, PIKC3A, and all RAS mutation status—will be presented. Conclusions: The observed median OS of 26.8 months in the KRAS wt population is comparable to that reported in prior pivotal studies involving weekly C plus FOLFOX or FOLFIRI in the first line. These results suggest that C plus FOLFOX or FOLFIRI in a once-every-2-weeks regimen is active and tolerable as first-line therapy in this Asia-Pacific study population and a convenient alternative to weekly administration.

e14610 Background: Preclinical and retrospective studies suggested antitumor activity for the incidental use of betablockers in various tumour types. Data regarding colorectal cancer are lacking. We assessed the correlation between the incidental use of betablockers and clinical outcome in colorectal cancer patients receiving first-line therapy. Methods: 235 patients treated with first-line chemotherapy alone (128 patients) and with Bevacizumab (107 patients) were analysed. Patients were stratified for betablockers use, age, sex, site of metastases, previous adjuvant chemotherapy and ECOG performance status. Results: 29 patients (12%) were on treatment with betablockers at the time of first-line therapy: 20 (16%) in the chemotherapy alone group and 9 in the bevacizumab group (8%). In both groups patients receiving or not betablockers were similar for all main clinical characteristics. In the chemotherapy alone group, patients receiving betablockers showed an improved response rate (60% vs. 33%, p=0.044) and overall survival (mOS 41.3 vs 25.7 months, p=0.03, HR:2.26, 95% CI: 1.05-3.24). Only a trend for improved progression free survival was noticed. In the 107 patients receiving chemotherapy with bevacizumab a trend towards a worse overall survival was seen for patients receiving betablockers, although this was not statistically significant (mOS 16 vs 23.7 months, p=0.26, HR:0.64, 95% CI: 0.22-1.49). No significant differences were seen in regards of progression free survival or different response rate patterns between the two groups. Conclusions: Our analysis confirms a potential prognostic role for the use of betablockers in colorectal cancer patients treated with chemotherapy. Our findings are in line with preclinical studies suggesting that beta-adrenergic signalling may regulate cancerogenesis and tumor invasiveness. Our analysis suggests a potential worse outcome for patients on betablockers receiving Bevacizumab-based treatment, although the small number of patients precludes any definitive conclusion. We suggest that in future prospective trials the incidental use of betablockers will be considered a stratification factor for clinical outcome.

4031 Background: Capecitabine plus oxaliplatin (CAPOX) is one of the standard first-line treatments for advanced or metastatic gastric cancer. Camrelizumab (SHR-1210, an anti–PD-1 antibody) shows promising anti-tumor activity in patients (pts) with advanced or metastatic gastric or gastroesophageal junction (G/GEJ) cancer. Camrelizumab combined with CAPOX for untreated G/GEJ cancer was assessed as a part of an ongoing multicenter, open-label phase 2 trial (cohort 1), and encouraging preliminary results were reported. Here, we present the updated safety and efficacy data. Methods: In this cohort, systemic treatment naïve pts with HER2– advanced or metastatic G/GEJ adenocarcinoma were given camrelizumab 200 mg on Day 1, capecitabine 1000 mg/m2 bid on Days 1–14 and oxaliplatin 130 mg/m2 on Day 1 of each 21-day-cycle for 4 to 6 cycles followed by camrelizumab 200 mg every 3 weeks plus apatinib 375 mg qd until disease progression or intolerable toxicity. The primary endpoint was objective response rate. Results: At data cutoff (Jan 20, 2019), 43 of the 48 enrolled pts were evaluable. Partial response was observed in 28 pts (65%), and 19 (44%) were confirmed. Stable disease in 14 pts and progressive disease in 10 pts were reported. Median estimates for duration of response and progression-free survival were not reached. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 9 pts (21%), included neutropenia, diarrhea, rash and elevated ALT, whereas none of the TRAEs was fatal. Ten pts without progression after 4–6 cycles of camrelizumab and CAPOX combination therapy all received camrelizumab plus apatinib as sequential therapy, and no new safety signals were observed. Conclusions: The updated results confirmed that camrelizumab plus CAPOX followed by camrelizumab plus apatinib was well tolerated with noteworthy responses as first-line therapy in advanced or metastatic G/GEJ cancer pts. Expansion of this cohort in a phase 3 study are under way. Clinical trial information: NCT03472365.

e21007 Background: Immunotherapy and targeted therapy have dramatically improved the survival of advanced melanoma patients (pts), but they show relative lower efficacy in Asian pts especially in acral and mucosal subtypes. Rh-Endostatin (endostar) is a potent endogenous inhibitor of angiogenesis. Previous studies have indicated that endostar combined with dacarbazine (DTIC) was effective in the treatment of metastatic melanoma. To further improve the effectiveness, this study was designed to observe the efficacy and safety of continuous infusion (CIV) of endostar combined with DTIC and cisplatin as the first line therapy for advanced melanoma pts. Methods: Pts with treatment naive, ECOG 0/1, and unresectable stage IIIC or IV melanoma were enrolled. DTIC (250 mg/m2, intravenous infusion, day 1-5), cisplatin (75 mg/m2, intravenous infusion, separated in 3 days) and endostar (15 mg/m2, CIV, day 1-14) were administered in a 28-day cycle until disease progression or intolerable toxicity. The primary endpoint was progression free survival (PFS). Secondary endpoints included disease control rate (DCR) and safety. Results: From January 2016 to May 2018, 64 pts were enrolled and 50 pts were evaluable. 26 pts were female. The median age was 50 years (range 28-71 years) old. 10/64 (15.6%) were primary mucosal and 21/64 (32.8%) were primary acral, 40 pts were at stage IV and 32% pts got BRAF mutation. At the last follow up of Dec 2018, 5 pts achieved partial response and 27 pts got stable disease. The objective response rate was 10%. The DCR was 64%. The median PFS was 6.0 months (95% CI 1.7-10.3 months). The median overall survival was not reached. The most common adverse events were nausea (56.25%), vomiting (31.25%) and leucopenia (29.7%). Grade 3-4 toxicity was few, one got intermittent palpitation and one got atrial fibrillation, which caused drug discontinuation and recovered to normal. Conclusions: Continuous infusion of endostar plus DTIC and cisplatin improved median PFS as the first line therapy for advanced melanoma. This combination therapy was well tolerated and might be recommended as the first line therapy for advanced melanoma. Clinical trial information: NCT03095079.

e20007 Background: Thymoma and thymic carcinoma are rare thymic epithelial tumours. This study investigated the efficacy of first-line gemcitabine and cisplatin combination chemotherapy in advanced thymoma and thymic carcinoma Methods: Retrospective review of patients with histologically-confirmed invasive, metastatic thymoma or thymic carcinoma treated with gemcitabine plus cisplatin as a first-line therapy between August 2008 and February 2016 at the Department of Respiratory Medicine II Peking University Cancer Hospital and Institute. The objective response rate was the primary end point. Results: Forty patients, 13 with thymoma and 27 with thymic carcinoma, were identified. Nine received gemcitabine and cisplatin combined with Endostar (injectable recombinant human Endostatin); 31 received gemcitabine and cisplatin only. Of the 13 patients with thymoma, four (30.8%) achieved a partial response (PR) and nine (69.2%) had stable disease (SD); no patients had a complete response (CR) or progressive disease (PD). Among the 27 patients with thymic carcinoma, 13 (48.1%) achieved a PR, 12 (44.4%) had SD and two (7.4%) had PD; no patients had a CR. In thymic carcinoma, progression free survival (PFS) was 25 months and median survival (OS) was 41 months; in thymoma, median PFS was 29 months and median OS was 77 months. As no patients achieved a complete response, objective response was defined as partial response in this study. Conclusions: This retrospective analysis indicates gemcitabine plus cisplatin has moderate efficacy and could represent a suitable first-line therapy for thymic carcinoma and thymoma, especially for patents who cannot tolerate anthracyclines.
