8571 Background: Carboplatin and etoposide is the current standard treatment for elderly extensive-disease small-cell lung cancer (ED-SCLC). The purpose of this study is to evaluate the efficacy and safety of carboplatin and irinotecan compared with carboplatin and etoposide in elderly Japanese patients with ED-SCLC in a randomized phase II/III design. Methods: Eligibility included histologically or cytologically proven SCLC, no previous systemic chemotherapy, performance status of 0 to 2, and aged 71 years or older. Patients received carboplatin (AUC 5 mg/ml/min on day 1) and etoposide (80 mg/m2 on day 1 to 3) (CE) every 3 weeks for 4 cycles or carboplatin (AUC 4 mg/ml/min on day 1) and irinotecan (50 mg/m2 on day 1 and 8) (CI) every 3 weeks for 4 cycles. In the phase II part, the primary endpoint was the objective response rate of the CI arm and the secondary endpoint was adverse events. In the phase III part, the primary endpoint was overall survival, and the secondary endpoints were progression-free survival, objective response rate, adverse events, and symptom score. This study was designed to confirm the superiority of CI arm in terms of overall survival over CE arm. The median survival time with CI arm was expected to be increased by 3.5 months with hazard ratio (HR) of 0.750 (10.5 vs. 14.0 months). The sample size was set at 250 to observe the required number of events of 227 with one-sided alpha level of 0.05, a power of 70%, an accrual period of 6.5 years, and a follow-up period of 1.5 years. Results: Between December 2013 and June 2019, 258 patients were randomized (CE arm, 129 patients; CI arm, 129 patients). The median age was 75 (range, 71-90). The characteristics of the patients were well balanced between CE arm and CI arm. Overall survival, progression-free survival, and objective response rate of CE arm vs. CI arm were 12.0 (95% CI, 9.3-13.7) vs. 13.2 (95% CI, 11.1-14.6) months (HR, 0.848 (95% CI, 0.650-1.105)) (one-sided P=0.11), 4.4 (95% CI, 4.0-4.7) vs. 4.9 months (95% CI, 4.5-5.2) (HR, 0.851 (95% CI, 0.664-1.090)) (two-sided P=0.21), and 59.7% (77 of 129) vs. 64.3% (83 of 129), respectively. Symptom score showed no significant difference between the arms. Higher incidences of myelosuppression of grade 3 or worse occurred with CE arm, whereas higher incidences of gastrointestinal toxicity of grade 3 or worse occurred with CI arm. Three treatment-related deaths including lung infection in CE arm and lung infection and sepsis in CI arm were observed. Conclusions: Efficacy tended to be favorable in carboplatin and irinotecan arm, but there was no statistically significant difference. These results indicate that carboplatin and etoposide is a still standard treatment in elderly Japanese patients with ED-SCLC. Clinical trial information: 000012605.

Glembatumumab vedotin (CDX-011, GV) is a fully human Immunoglobulin G2 monoclonal antibody directed against glycoprotein NMB coupled via a peptide linker to monomethyl auristatin E (MMAE), a potent cytotoxic microtubule inhibitor. This phase II study evaluated the overall response rate and safety of GV, glycoprotein NMB (GPNMB) expression, and survival in patients with metastatic uveal melanoma. Eligible patients with metastatic uveal melanoma who had not previously been treated with chemotherapy received GV 1.9 mg/kg every three weeks. The primary endpoint was the objective response rate (ORR). Secondary endpoints included GPNMB expression, progression-free survival (PFS), overall survival (OS), and toxicity analysis. GPNMB expression was assessed pre- and post-treatment via immunohistochemistry for patients with available tumor tissue. Out of 35 patients who received treatment, two patients had confirmed partial responses (PRs; 6%), and 18 patients had a stable disease (SD; 51%) as the best objective response. 38% of the patients had stable disease >100 days. The grade 3 or 4 toxicities that occurred in two or more patients were neutropenia, rash, hyponatremia, and vomiting. The median progression-free survival was 3.1 months (95% CI: 1.5–5.6), and the median overall survival was 11.9 months (95% CI 9.0–16.9) in the evaluable study population. GV is well-tolerated in metastatic uveal melanoma. The disease control rate was 57% despite a low objective response rate. Exploratory immune correlation studies are underway to provide insight into target saturation, combination strategies, and antigen release.

Introduction Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate.

Purpose Objective responses are reported in 34% to 37% of patients with programmed death-1 (PD-1)–naïve advanced melanoma treated with PD-1 inhibitors. Pre-existing CD8+ T-cell infiltrate and interferon (IFN) gene signature correlate with response to PD-1 blockade. Here, we report a phase Ib/II study of pembrolizumab/pegylated (PEG)-IFN combination in PD-1–naïve advanced melanoma. Patients and Methods PEG-IFN (1, 2, and 3 μg/kg per week) was dose escalated using a modified toxicity probability interval design in three cohorts of four patients each, whereas pembrolizumab was dosed at 2 mg/kg every 3 weeks in the phase Ib portion. Thirty-one patients were enrolled in the phase II portion. Primary objectives were safety and incidence of dose-limiting toxicities. Secondary objectives included objective response rate, progression-free survival (PFS), and overall survival. Results Forty-three patients with stage IV melanoma were enrolled in the phase Ib and II portions of the study and included in the analysis. At the data cutoff date (December 31, 2017), median follow-up duration was 25 months (range, 1 to 38 months). All 43 patients experienced at least one adverse event; grade 3/4 treatment-related adverse events occurred in 21 of 43 patients (48.8%). Objective responses were seen at all three dose levels among 43 evaluable patients. The objective response rate was 60.5%, with 46.5% of patients exhibiting ongoing response. Median PFS was 11.0 months in all patients and unreached in responders, whereas median overall survival remained unreached in all patients. The 2-year PFS rate was 46%. Conclusion Pembrolizumab/PEG-IFN demonstrated an acceptable toxicity profile with promising evidence of clinical efficacy in PD-1–naïve metastatic melanoma. These results support the rationale to further investigate this pembrolizumab/PEG-IFN combination in this disease.

Purpose Metastatic pancreatic ductal adenocarcinoma is characterized by excessive hyaluronan (HA) accumulation in the tumor microenvironment, elevating interstitial pressure and impairing perfusion. Preclinical studies demonstrated pegvorhyaluronidase alfa (PEGPH20) degrades HA, thereby increasing drug delivery. Patients and Methods Patients with previously untreated metastatic pancreatic ductal adenocarcinoma were randomly assigned to treatment with PEGPH20 plus nab-paclitaxel/gemcitabine (PAG) or nab-paclitaxel/gemcitabine (AG). Tumor HA levels were measured retrospectively using a novel affinity histochemistry assay. Primary end points were progression-free survival (PFS; overall) and thromboembolic (TE) event rate. Secondary end points included overall survival, PFS by HA level, and objective response rate. An early imbalance in TE events in the PAG arm led to a clinical hold; thereafter, patients with TE events were excluded and enoxaparin prophylaxis was initiated. Results A total of 279 patients were randomly assigned; 246 had HA data; 231 were evaluable for efficacy; 84 (34%) had HA-high tumors (ie, extracellular matrix HA staining ≥ 50% of tumor surface at any intensity). PFS was significantly improved with PAG treatment overall (hazard ratio [HR], 0.73; 95% CI, 0.53 to 1.00; P = .049) and for patients with HA-high tumors (HR, 0.51; 95% CI, 0.26 to 1.00; P = .048). In patients with HA-high tumors (PAG v AG), the objective response rate was 45% versus 31%, and median overall survival was 11.5 versus 8.5 months (HR, 0.96; 95% CI, 0.57 to 1.61). The most common treatment-related grade 3/4 adverse events with significant differences between arms (PAG v AG) included muscle spasms (13% v 1%), neutropenia (29% v 18%), and myalgia (5% v 0%). TE events were comparable after enoxaparin initiation (14% PAG v 10% AG). Conclusion This study met its primary end points of PFS and TE event rate. The largest improvement in PFS was observed in patients with HA-high tumors who received PAG. A similar TE event rate was observed between the treatment groups in stage 2 of the trial.

Background Bevacizumab is an antiangiogenic agent active in patients with recurrent malignant gliomas. However, evidence for its clinical efficacy is relatively limited so that bevacizumab is approved for this indication in Canada and the United States, but not in the European Union. We reviewed the effectiveness of bevacizumab in patients with recurrent brain tumour using a large population database. Methods This was a retrospective, multicentre, study conducted at the BC Cancer Agency, a public cancer care organisation for the residents of the Canadian province of British Columbia. Cases were identified from the provincial registry and drug database. Patients were eligible if they were treated with bevacizumab with or without lomustine or etoposide for recurrent brain tumour between April 2011 and March 2014. The primary end points were progression-free survival. Secondary endpoints were overall survival and objective response rate. Results A total of 160 patients were included, with a median age of 55 years. The most common diagnosis was glioblastoma multiforme (70.6%), followed by oligodendroglioma (10.6%). Half of the patients had prior metronomic dosing of temozolomide. The median duration of therapy was 3 months. The median progression-free survival was 4.0 months and the 6-month progression-free survival was 29.4%. The median overall survival was 7 months and the 9-month and 12-month overall survival was 28.1% and 20.6%, respectively. The objective response rate was 23.1%. The most common documented reason for bevacizumab discontinuation was disease progression (66.9%), followed by toxicity (6.9%). Conclusions Bevacizumab therapy seems to be effective in delaying disease progression in patients with recurrent brain tumour, but with limited benefits on the overall survival, when used outside the clinical trial setting.

PURPOSE Treatment options are limited for patients with recurrent and/or metastatic (R/M) cutaneous squamous cell carcinoma (cSCC); mortality rates exceed 70% in patients with distant metastases. Here, we present the first interim analysis of the R/M cSCC cohort from the 2-cohort—locally advanced and R/M—phase II KEYNOTE-629 study. PATIENTS AND METHODS Patients with R/M cSCC not amenable to surgery or radiation received pembrolizumab 200 mg every 3 weeks. The primary end point was objective response rate per RECIST v1.1. Secondary end points were duration of response, disease control rate, progression-free survival, overall survival, and safety. RESULTS At data cutoff (April 8, 2019), median follow-up of 105 enrolled patients in the R/M cohort was 11.4 months (range, 0.4 to 16.3 months). Objective response rate was 34.3% (95% CI, 25.3% to 44.2%; 4 complete responses, 32 partial responses), and disease control rate was 52.4% (95% CI, 42.4% to 62.2%). Median duration of response was not reached (range, 2.7 to 13.1+ months; ‘+’ refers to ongoing response at data cutoff). Median progression-free survival was 6.9 months (95% CI, 3.1 months to 8.5 months). Median overall survival was not reached (95% CI, 10.7 months to not reached). Treatment-related adverse events occurred in 66.7% of patients (n = 70), the most common of which were pruritus (n = 15; 14.3%), asthenia (n = 14; 13.3%), and fatigue (n = 13; 12.4%). Grade 3 to 5 treatment-related adverse events occurred in 5.7% (n = 6) of patients. One patient died of treatment-related cranial nerve neuropathy. CONCLUSION Pembrolizumab demonstrated effective antitumor activity; clinically meaningful, durable responses; and acceptable safety in primarily elderly patients with R/M cSCC, supporting its use in clinical practice. Pembrolizumab adverse events in this study were consistent with its established safety profile.

e11538 Background: It is extremely important to identify proper cytotoxic agents for TNBC which had limited choices except chemotherapy. Capecitabine are well established as a major chemotherapeutic agent in metastatic setting. The efficacy of capecitabine-based chemotherapy has not been prospectively studied in TNBC and data remains scant. This study was designed to investigate the efficacy of capecitabine-based doublets in the treatment of metastatic TNBC. Methods: Eligible metastatic TNBC women with measurable diseases were recruited to receive either TX regimen (docetaxel 75mg/m2 iv d1 plus capecitabine 1000mg/m2 bid, d1-14,q3w) or NX regimen (vinorelbine 25mg/m2 iv d1, 8 plus capecitabine 1000mg/m2 bid, d1-14, q3w) at the discretion of physicians for up to 6 cycles, until disease progression or unacceptable toxicity. The primary endpoint was objective response rate and secondary endpoints included progression free survival (PFS), overall survival (OS). Results: 45 mTNBC patients, 27 in TX and 18 in NX were recruited, mostly (73.3%) as 1st line and the remaining as the 2nd line. The total objective response rate was 20.0% and clinical benefit rate was 62.2%. After a median follow-up of 28 months, PFS was 5.2 months (95%CI, 4.1-6.3mons) and OS was 18.2months (95%CI, 8.7-27.7mons). Almost half of the patients (22/45) progressed during treatment or within one month of the treatment discontinuation. PFS was significantly longer if patients got CR/PR (9.6 vs 4.3mons, P=0.015). When comparing two doublets, the response rate was numerically but not statistically lower in TX group than in NX group (14.8% vs 27.8%, P=0.449). Similarly, no difference was found in either PFS (4.9 vs 5.2 mons, P=0.483) or OS (21.5 vs 18.3 mons, P=0.964) between two regimens. Conclusions: Although the overall survival seems to be reasonable, efficacy of capecitabine-contained TX or NX regimen was relatively poor in terms of tumor remission and progression free survival in mTNBC patients, suggesting capecitabine may have limited potency in this subtype. These two combinations may be considered to be acceptable but may not be recommended as prior choice for mTNBC patients.

The Impact

e20609 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 second- and further-line therapy. Methods: A systematic literature review of randomized clinical trials of systemic treatment for patients with stage IIIB/IV NSCLC receiving second- and further-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: 146 trials (43,061 patients) fulfilled the eligibility criteria. In all treatment arms, the mean ORR, median PFS, and median OS were 12.2% (standard deviation [SD] 11.2%), 3.2 months (SD 1.3), and 9.6 months (SD 4.1), respectively. ORR and PFS had very weak (R = 0.181; 95% CI: 0.016-0.337) and weak (R = 0.254; 95% CI: 0.074-0.418) relationships, respectively, with OS. However, within trials that did not allow crossover and reported balanced post-progression treatments, ORR and PFS had moderate (R = 0.528; 95% CI: 0.081-0.798) and strong (R = 0.778; 95% CI: 0.475-0.916) relationships, respectively, with OS. STE estimation indicated that trials that show statistically significant treatment effect size of ≥41.0% ORR or ≥4.15 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.
