e18731 Background: For advanced non-small cell lung cancer (NSCLC), evidence from clinical trials indicates the superiority of pembrolizumab (P) than chemotherapy (C) in PD-L1 positive patients and superiority of P+C than C among PD-L1 unselected patients. Meta-analysis from different clinical trials stated P+C failed to improve overall survival (OS) or progression-free survival (PFS) compared with P alone. This study used real-world data of PD-L1+ patients with advanced NSCLC to compare treatment effect of P with P+C. Methods: A retrospective analysis of adult patients diagnosed between 2015-2020 with stage IV NSCLC with PD-L1+ and without EGFR/ALK mutation was examined using de-identified Syapse Learning Health Network(LHN). We compared the patients with first-line (1L) treatment of pembrolizumab + carboplatin + chemo (P+C) and patients with 1L treatment of P only (P). Patient characteristics and survival outcomes including real-world OS (rwOS) and real-world time to next treatment (rwTTNT) were collected. Results: 485 patients were included: 231 on P+C and 254 on P. The two groups are similar in race, primary tumor histology and ECOG, and P are older in age and have more female. The median rwOS for P+C is longer than P (13.2 vs 11.0 month), 1 year survival probability is higher (55% vs 49%), but 2 year survival probability is lower (34% vs 39%). Coxph model shows no significant difference between two groups (HR=0.89, 95% CI 0.69-1.14, p=0.34). Subgroup analysis of patients age≥75 shows median rwOS for P+C is shorter than P (8.7 vs 13.2 month), 1 year survival probability is lower (46% vs 51%). Coxph model shows no significant difference between two groups (HR=1.32, 95% CI 0.81-2.16, p=0.27). In each treatment group, the median rwOS for female is longer than male (13.2 vs 7.9 month in P, 15.8 vs 12.2 month in P+C), and 1 year survival probability is higher (52% vs 45% in P, 59% vs 53% in P+C). Coxph model shows no significant difference between female and male (HR=0.81, 95% CI 0.58-1.15, p=0.23 in P; HR=0.90, 95% CI 0.62-1.30, p=0.57 in P+C). Conclusions: Among patients with PD-L1+ advanced NSCLC, there is no significant difference in rwOS for patients with 1L treatment of P+C or P alone.[Table: see text]

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.

Aim: To evaluate treatment results in advanced/metastatic melanoma patients treated with anti-PD-1 immunotherapy in routine practice in oncology centers in Poland. Methods: Multicenter retrospective analysis included 499 patients with unresectable/metastatic (stage IIIC–IV) melanoma treated with anti-PD-1 in first-line therapy. Results: Estimated median overall survival (OS) and progression-free survival (PFS) were 19.9 and 7.9 months, respectively. Multivariate analysis confirmed that ECOG 0, no brain metastases, normal lactate dehydrogenase level and occurrence of immune-related adverse events (irAEs) were statistically significantly associated with improved OS and PFS. Any irAE occurred in 24% of patients. Grade 3 or Grade 4 irAEs occurred in 6% of patients. Conclusion: Analysis revealed a slightly worse OS in real-world treatment in comparison to clinical trials (KEYNOTE-006 and CheckMate 066). Polish population treatment results are similar to other studies of real-world data. PFS and ORR are similar in our research and clinical trials.

281 Background: TACE and lenvatinib has each shown to prolong overall survival in patients with unresectable HCC, combination of which may also improve clinical outcomes and have been widely used in the real world accordingly. However, the optimal timing of adding on lenvatinb to TACE remains unclear. We are aiming to evaluate the efficacy and safety between two combination strategies. Methods: From Nov 2018 to Jun 2020, 79 consecutive patients had received a combination treatment of lenvatinib and TACE. Patients followed up for more than 2 months were included in this analysis. They were classified as early-combination group(add on lenvatinib before or after the first TACE ) and late-combination group(add on lenvatinib after at least two procedures of TACE ). Tumor response and progression-free survival (PFS,time from the first day of prescribing lenvatinib to progression or death) were assessed according to RECIST1.1 criteria. Liver function were also evaluated at baseline and every 2 months later. AEs were recorded during the combination treatment period according to CTCAE 5.0. Results: A total of 48 u-HCC patients was finally enrolled. Median follow-up in all patients was 9.3(5.3-14.3)months. Patients’ baseline characteristics were similar in two groups. For early-combination group(n=22)and late-combination group(n=26), the mean age was 65±9.7 and 61±11.6years(p=0.2);BCLC stage C HCC was 59% and 54%(p=0.89);and Child-Pugh A proportion was 81.8% and 77%(p=0.73) respectively. The objective response rate(ORR) was 22.9% in total 48 cases. There was no significant difference in response rate (18.2% vs 26.9%, P=0.51) or disease control rate (90.9% vs 92.3%, P=1.00). Median PFS was significantly longer in the early-combination group than that in late-combination group (14.5 vs 8.9 months; p=0.048). The safety profile was similar between two groups. Grade 3/4 adverse events were 3 (13.6%) and 2 cases(7.7%) respectively (P=0.65). Conclusions: This is to date the first real-world data of the combination timing of lenvatinib with TACE in u-HCC patients. Early-combination strategy may be a better option for the u-HCC patients with a longer mPFS.

Background Combined androgen blockade (cab) is a promising treatment modality for prostate cancer (pca). In the present meta-analysis, we compared the efficacy and safety of first-line cab using an antiandrogen (aa) with castration monotherapy in patients with advanced pca.Methods PubMed, embase, Cochrane, and Google Scholar were searched for randomized controlled trials (rcts) published through 12 December 2016. Hazard ratios (hrs) with 95% confidence intervals (cis) were determined for primary outcomes: overall survival (os) and progression-free survival (pfs). Subgroup analyses were performed for Western compared with Eastern patients and use of a nonsteroidal aa (nsaa) compared with a steroidal aa (saa).Results Compared with castration monotherapy, cab using an aa was associated with significantly improved os (n = 14; hr: 0.90; 95% ci: 0.84 to 0.97; p = 0.003) and pfs (n = 13; hr: 0.89; 95% ci: 0.80 to 1.00; p = 0.04). No significant difference in os (p = 0.71) and pfs (p = 0.49) was observed between the Western and Eastern patients. Compared with castration monotherapy, cab using a nsaa was associated with significantly improved os (hr: 0.88; 95% ci: 0.82 to 0.95; p = 0.0009) and pfs (hr: 0.85; 95% ci: 0.73 to 0.98; p = 0.007)—a result that was not achieved with cab using a saa. The safety profiles of cab and monotherapy were similar in terms of adverse events, including hot flushes, impotence, and grade 3 or 4 events, with the exception of risk of diarrhea and liver dysfunction or elevation in liver enzymes, which were statistically greater with cab using an aa.Conclusions Compared with castration monotherapy, first-line cab therapy with an aa, especially a nsaa, resulted in significantly improved os and pfs, and had an acceptable safety profile in patients with advanced pca.

7109 Background: Cisplatin plus vinorelbine is a commonly used regimen for first-line therapy of advanced NSCLC, achieving response rates of 20–30% and median survival times of 6 to 11 months (mths). An earlier phase II trial investigated cetuximab in combination with cisplatin and vinorelbine in this setting and found improved response rates in the cetuximab arm, warranting this larger phase III trial. Methods: Patients (pts) with EGFR-expressing advanced NSCLC (stage IIIB with documented malignant pleural effusion and stage IV) were randomized 1:1 either to Group A (cetuximab 400 mg/m2 initial dose then 250 mg/m2 weekly, cisplatin 80 mg/m2 on day 1, vinorelbine 30 mg/m2 on day 1 and 8) or to Group B (cisplatin and vinorelbine as before) for a maximum of 6 three-weekly cycles. Cetuximab was administered until progression or unacceptable toxicity. Primary endpoint is overall survival time; secondary endpoints are progression-free-survival, tumor response, disease control, safety, and quality of life. Enrollment of 1,100 pts was planned to show an increase of median survival time of 25% with 90% power. The Data Safety Monitoring Board (DSMB) performed an independent preplanned safety analysis from the first 370 pts. Patients were followed for a minimum of 6 weeks (2 cycles). Results: Since November 2004, 1,037 pts have been randomized, 689 are under treatment, and 348 pts have discontinued the study. Demographics of the first 370 pts reflected known advanced NSCLC characteristics: 91% stage IV, median age 60 yrs (31–79), 38% female, 80% ECOG PS 0/1, 52% adenocarcinoma, 30% squamous cell carcinoma; 29% never-smokers, 17% Asian. The ten most frequent adverse events were: nausea, neutropenia, vomiting, anorexia, fatigue, constipation, anemia, febrile neutropenia, rash, and diarrhoea. Conclusions: The trial continued after review of all relevant baseline and safety information from the first 370 pts. Recruitment is ongoing. [Table: see text]

7590 Background: The median age of advanced NSCLC pts in the US is 71 years; yetelderly pts (≥70 years) are generally undertreated, with only ≈30% receiving systemic therapy. Hence, better, more tolerable therapeutic options are needed for this cohort. In a phase III trial nab-paclitaxel (nab-P, 130 nm albumin-bound paclitaxel particles) + carboplatin (C) vs solvent-based paclitaxel (sb-P) + C, significantly improved ORR, the primary endpoint (25% vs 33%, P = 0.005), with a 1-month improvement in OS (P = NS) and improved safety. This analysis evaluated efficacy and safety in pts ≥70 and <70 years old. Methods: Pts with untreated stage IIIB/IV NSCLC and with an ECOG score of 0/1 were randomized 1:1 (stratified by age [≥70 vs <70 years], region, stage, gender, and histology) to C AUC 6 day 1 and either nab-P 100 mg/m2 on days 1, 8, 15 or sb-P 200 mg/m2 day 1 q 21 days. ORR and progression-free survival (PFS) were determined by blinded centralized review. Results: Of the phase III study population, 15% were elderly (156/1052; 74 pts in the nab-P/C and 82 in the sb-P/C arms). Most elderly pts were male (72%), Caucasian (71%), and had stage IV disease (64%). In pts both ≥70 and <70 years old, ORR was higher in the nab-P/C vs sb-P/C arm (≥70: 34% vs 24%, P = 0.196; <70: 32% vs 25%, P = 0.013). In pts ≥70 years old, PFS trended in favor of nab-P/C (median 8.0 vs 6.8 months, HR: 0.687, P = 0.134); OS was significantly improved (median 19.9 vs 10.4 months, HR: 0.583, P = 0.009). In contrast, PFS (6.0 vs 5.8 median months, HR: 0.903, P = 0.256) and OS (11.4 vs 11.3 median months, HR: 0.999, P = 0.988) were similar for both treatment arms in pts <70 years old. Adverse events were similar in pts ≥70 years old vs the entire study population, with less grade 3/4 neutropenia (P < 0.05) and neuropathy (P < 0.05) and increased thrombocytopenia (P = NS) and anemia (P < 0.05) in the nab-P/C vs sb-P/C arms. In pts ≥70 years old, patient-reported FACT-taxane subscales revealed significantly less neuropathy, pain, and hearing loss in the nab-P/C vs sb-P/C arms (P < 0.001). Conclusions: In elderly pts with advanced NSCLC, nab-P/C as first-line therapy was well tolerated and led to improved ORR and PFS, with significantly longer OS vs sb-PC.

9502 Background: First-line therapy for advanced NSCLC includes PD-1 checkpoint inhibitor (ICI) monotherapy, and in combination with chemotherapy. Combination ICI have also demonstrated better survival compared to chemotherapy (CM-227). In CCTG BR.34, we compared overall survival (OS) in patients with advanced NSCLC receiving first-line durvalumab plus tremelimumab (DT) with or without platinum doublet chemotherapy (CT). Methods: This international, open-label, randomized trial accrued 301 participants from Canada and Australia, with stage IV NSCLC, EGFR/ALK wildtype, ECOG PS 0/1. Patients were randomized to DT for 4 cycles or DT+CT (pemetrexed- or gemcitabine-platinum), with ongoing D or D + pemetrexed (non-squamous) maintenance until disease progression. Stratification factors included histology, stage IVA v. IVB and smoking status. The primary endpoint was OS; secondary endpoints included progression-free survival (PFS), objective response rate (ORR = CR + PR) and adverse events (AEs). Results: At a median follow up of 16.6 months, no significant difference in OS was seen between the two treatment arms, with a median OS of 16.6 months with DT+CT v. 14.1 months with DT, (estimated HR 0.88, 90% CI 0.67-1.16). PFS was significantly improved in the DT+CT arm (stratified HR 0.67, 95% CI 0.52-0.88; medians 7.7 v. 3.2 months). ORR was higher in the DT+CT arm, 28% v. 14%, (odds ratio 2.1, p=0.001). Preplanned subgroup analysis demonstrated no significant differences in treatment outcomes by plasma TMB (<20 v. ≥20 mut/Mb, Guardant OMNI), age, sex, or smoking status. There was a trend to improved OS with DT+CT in the subgroup with PD-L1 TPS≥50%, (HR 0.64, 95% CI 0.40-1.04, p=0.07). Plasma TMB<20 mut/Mb was associated with shorter survival in both treatment groups (HR 1.99, 95% 1.3-3.1). Toxicity was greater in the DT+CT arm, with grade≥3 adverse events in 82% v. 70%, (p=0.02), most commonly dyspnea, nausea and cough. The incidence of immune-related adverse events was similar between arms (colitis 11%, pneumonitis 6%, endocrinopathy 21%). Grade 5 events occurred in 2.7%, (5 with DT+CT, 3 with DT). Conclusions: The addition of CT to first-line DT did not improve OS in advanced NSCLC. CT+DT improved ORR and PFS, and was associated with greater toxicity. No differential effects were seen by PD-L1 TPS nor bTMB. These data suggest that adding chemotherapy to ICI may be beneficial in those with PD-L1 TPS >=50%, and warrant further analysis in independent datasets. Clinical trial information: NCT03057106 .

IntroductionSomatic mutations in STK11 and KEAP1, frequently comutated in non-squamous non-small cell lung cancer (NSQ NSCLC), have been associated with poor response to immune checkpoint blockade (ICB). However, previous reports lack non-ICB controls needed to properly ascertain the predictive nature of those biomarkers. The objective of this study was to evaluate the predictive versus prognostic effect of STK11 or KEAP1 mutations in NSQ NSCLC.MethodsPatients diagnosed with stage IIIB, IIIC, IVA or IVB NSQ NSCLC from a real-world data cohort from the Flatiron Health Network linked with genetic testing from Foundation Medicine were retrospectively assessed. Real-world, progression-free survival (rwPFS) and overall survival (OS) were calculated from time of initiation of first-line treatment.ResultsWe analysed clinical and mutational data for 2276 patients including patients treated with anti-programmed death-1 (PD-1)/anti-programmed death ligand 1 (PD-L1) inhibitors at first line (n=574). Mutations in STK11 or KEAP1 were associated with poor outcomes across multiple therapeutic classes and were not specifically associated with poor outcomes in ICB cohorts. There was no observable interaction between STK11 mutations and anti-PD-1/anti-PD-L1 treatment on rwPFS (HR, 1.05; 95% CI 0.76 to 1.44; p=0.785) or OS (HR, 1.13; 95% CI 0.76 to 1.67; p=0.540). Similarly, there was no observable interaction between KEAP1 mutations and treatment on rwPFS (HR, 0.93; 95% CI 0.67 to 1.28; p=0.653) or OS (HR, 0.98; 95% CI 0.66 to 1.45; p=0.913).ConclusionOur results show that STK11-KEAP1 mutations are prognostic, not predictive, biomarkers for anti-PD-1/anti-PD-L1 therapy.

Abstract Objective The aim of the present work was to investigate the clinical efficacy of first-line chemotherapy regimens in the treatment of advanced non-small cell lung cancer (NSCLC) through a comprehensive network meta-analysis (NMA). Methods The prospective randomized controlled clinical trials relevant to 10 first-line chemotherapy regimens in the treatment of advanced NSCLC were systematic electronic search in the databases of Pubmed, Embase, Cochrane Library and CNKI. The combined direct or indirect objective response rate (ORR) between each of the 10 first-line chemotherapy regimens was calculated. Results Seventeen prospective clinical trials of first-line chemotherapy regimens in treatment of advanced NSCLC were included in the NMA. The 10 treatment regimens including A = cisplatin + gemcitabine, B = carboplatin + gemcitabine, C = gemcitabine, D = carboplatin + paclitaxel, E = paclitaxel + gemcitabine, F = docetaxel + carboplatin, G = gemcitabine + vinorelbine, H = pemetrexed + carboplatin, I = cisplatin + pemetrexed and J = cisplatin + docetaxel were compared in the present NMA. Direct pooled results indicated that the ORR was not statistically different (P all > 0.05). However, NMA showed that the combined ORR for regimens A (OR = 1.47, 95% CI: 0.80–2.81), B (OR = 3.22, 95% CI: 1.45–6.923), D (OR = 3.30, 95% CI: 1.22–9.33), E (OR = 4.36, 95% CI: 1.64–12.82), G (OR = 3.72, 95% CI: 1.12–12.83) and I (OR = 5.80, 95% CI: 2.04–17.86) was superior to regimen C. Rank probability analysis indicated that regimen C = gemcitabine and regimen I = cisplatin + pemetrexed had the highest probability of inferior and superior treatment ORR among the 10 first-line chemotherapy regimens. Conclusion Cisplatin + pemetrexed may have particularly prominent ORR for advanced NSCLC as the first-line chemotherapy regimen.
