PURPOSE The VIT-0910 trial was conducted to evaluate efficacy and safety of the vincristine-irinotecan combination with and without temozolomide (VIT and VI, respectively) in relapsed or refractory rhabdomyosarcoma (RMS). METHODS In this randomized European phase II trial, patients age 0.5-50 years received 21-day cycles combining vincristine (1.5 mg/m2 once a day on day 1 and day 8) and irinotecan (50 mg/m2 once a day from day 1 to day 5) with and without temozolomide (125 mg/m2 once a day from day 1 to day 5 and 150 mg/m2 once a day from cycle 2), until progression or unacceptable toxicity. The primary end point was objective response rate after two cycles. Secondary end points included best response, progression-free survival, overall survival, and adverse events. A Simon 2-stage design was initially planned to separately analyze 40 patients/arm. After amendment, the trial sample size was increased to 120 and a comparison between arms, adjusted for confounding factors, was added to the statistical plan (ClinicalTrials.gov, NCT01355445 ). RESULTS Overall, 120 patients (60 per arm) were recruited in 37 European centers. The median age was 11 years (range, 0.75-45); 89% of patients had a relapsed RMS. The objective response rate was 44% (24 of 55 evaluable patients) for VIT versus 31% (18 of 58) for VI (adjusted odds ratio, 0.50; 95% CI, 0.22 to 1.12; P = .09). The VIT arm achieved significantly better overall survival (adjusted hazard ratio, 0.55; 95% CI, 0.35 to 0.84; P = .006) compared with VI, with consistent progression-free survival results (adj-hazard ratio, 0.68; 95% CI, 0.46 to 1.01; P = .059). Overall, patients experienced adverse events ≥ grade 3 more frequently with VIT than VI (98% v 78%, respectively; P = .009), including a significant excess of hematologic toxicity (81% v 61%; P = .025). CONCLUSION The addition of temozolomide to VI improved chemotherapy efficacy for patients with relapsed RMS, with manageable increase in toxicity. VIT is considered the new standard treatment in these patients in the European paediatric Soft Tissue Sarcoma Group and will be the control arm in the next randomized trial.

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.

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 To the best of our knowledge, this study is the first to compare dual inhibition of PI3K/mammalian target of rapamycin (mTOR) by apitolisib (GDC-0980) against single inhibition of mTORC1 by everolimus in metastatic renal cell carcinoma (mRCC). Patients and Methods Patients with clear-cell mRCC who progressed on or after vascular endothelial growth factor–targeted therapy were randomly assigned to apitolisib 40 mg once per day or to everolimus 10 mg once per day. End points included progression-free survival, safety, overall survival, and objective response rate. Biomarker assessments were conducted. Results Eighty-five patients were randomly assigned. After 67 events, stratified analysis revealed that median progression-free survival was significantly shorter for apitolisib than for everolimus (3.7 v 6.1 months; hazard ratio, 2.12 [95% CI, 1.23 to 3.63; P < .01]); apitolisib was not favored in any stratification subgroup. Median overall survival was not significantly different but trended in favor of everolimus (16.5 v 22.8 months; hazard ratio, 1.77 [95% CI, 0.97 to 3.24; P = .06]). The objective response rate was 7.1% for apitolisib and 11.6% for everolimus. Patients administered apitolisib with a greater incidence of grade 3 to 4 adverse events were more likely to discontinue treatment (31% v 12% for everolimus). No drug-related deaths were observed. Apitolisib in comparison with everolimus was associated with substantially more high-grade hyperglycemia (40% v 9%) and rash (24% v 2%). Apitolisib pharmacokinetics suggested a relationship between exposure, and rash and hyperglycemia. Retrospective biomarker analyses revealed a relationship between VHL mutation status and outcome with everolimus but not with apitolisib. High hypoxia-inducible factor 1α protein expression was associated with better outcome in both arms. Conclusion This study demonstrated that dual PI3K/mTOR inhibition by apitolisib was less effective than was everolimus in mRCC, likely because full blockade of PI3K/mTOR signaling resulted in multiple on-target adverse events. VHL mutation and hypoxia-inducible factor 1α expression may be predictive of an mTOR inhibitor benefit, although prospective validation is required.

Recurrent Brain Tumour

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.

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.

Aim: PD-1 inhibitors have a leading role among immunotherapy while its efficacy on colorectal cancer (CRC) patients did not reach consensus and the small sample size remains as a limitation. Therefore, we undertook a meta-analysis on the effects of the monotherapy anti-PD-1 inhibitors in treating metastatic colorectal cancer (mCRC). Materials & methods: We searched databases to identify studies on efficacy of anti-PD-1 inhibitor on CRC. Objectives were objective response rate, progression-free survival rate, disease control rate and overall survival rate with their 95% CI. Results: The overall survival rate at 1-year was 64.2% (95% CI: 0.46–0.83). Disease control rate was 56.5% (CI: 0.27–0.86) and the objective response rate as 19.7% (CI: 0.08–0.32). The 1-year-progression-free survival rate was 38.4% (CI: 0.12–0.66). Sensitivity analysis and subgroup analysis were also conducted. Conclusion: The monotherapy anti-PD-1 inhibitors are effective in treating mCRC and could be a new option for dMMR mCRC patient in first-line treatment.

Aim: Examine outcomes in sunitinib-treated patients by International Metastatic RCC Database Consortium (IMDC) or Memorial Sloan-Kettering Cancer Center (MSKCC) risk factors. Patients & methods: Patients enrolled in STAR-TOR registry (n = 327). End points included overall survival, progression-free survival and objective response rate. Results: Overall survival was similar for IMDC 0 versus 1 (p = 0.238) or 2 versus ≥3 (p = 0.156), but different for MSKCC (0 vs 1, p = 0.037; 2 vs ≥3, p = 0.001). Progression-free survival was similar for IMDC 2 versus 3 (p = 0.306), but different for MSKCC (p = 0.009). Objective response rate was different for IMDC 1 (41.9%) and 2 (29.5%) and similar for MSKCC 1 (34.4%) and 2 (31.0%). Conclusion: Outcome data varied according to IMDC or MSKCC. MSKCC model accurately stratify patients into risk groups. Clinical trial registration: NCT00700258 (ClinicalTrials.gov)
