Abstract Purpose The aim of this retrospective review was to compare the efficacy and safety of the atezolizumab plus carboplatin and nab-paclitaxel regimen versus the carboplatin and nab-paclitaxel regimen as front-line management for treatment-naïve, metastatic nonsquamous programmed death-ligand 1 (PD-L1)-positive non-small cell lung cancer (NSCLC) in a selected population. Methods Consecutive patients with untreated, metastatic nonsquamous PD-L1-positive NSCLC who initially received the atezolizumab plus carboplatin and nab-paclitaxel (ACN) regimen or carboplatin and nab-paclitaxel (CN) regimen were retrospectively identified in two medical institutions from 2017 to 2020. The co-primary end points were overall survival (OS) and progression-free survival (PFS); secondary end point was the rate of key adverse events (AEs). Results In sum, 171 patients were retrospectively analysed, 47 of whom were excluded according to the criteria used in this study, leaving 124 patients (ACN: n = 60, median age 64 years [range 46–75]; CN: n = 64, 63 years [47–72]). The median duration of follow-up was 27 months [range 1–37]. At the final follow-up, the median OS was 19.9 months (95% confidence interval [CI], 16.3–22.5) in the ACN group vs. 14.8 months (95% CI 12.5–17.2) in the CN group (hazard ratio [HR] 0.51, 95% CI 0.33–0.77; p = 0.001). A marked distinction in the median PFS was seen (8.5 months [95% CI 6.7–9.4] in the ACN group vs. in the CN group [5.1 months [95% CI 3.6–6.8; HR 0.60; 95% CI 0.38–0.95; p = 0.005]). The rates of the key AEs (neutropenia and anaemia) were greater in the ACN group than in the CN group (all p < 0.05), but these AEs were manageable. Conclusion Among selected populations of individuals with treatment-naïve, metastatic nonsquamous PD-L1-positive NSCLC, atezolizumab combined with carboplatin and nab-paclitaxel chemotherapy might have encouraging anticancer activity, with a tolerable safety profile.

Selpercatinib, a novel, highly selective and potent, inhibitor of RET, demonstrated clinically meaningful antitumor activity with manageable toxicity in heavily pretreated and treatment-naive RET fusion-positive non-small-cell lung cancer patients in a Phase I/II clinical trial. LIBRETTO-431 (NCT04194944) is a randomized, global, multicenter, open-label, Phase III trial, evaluating selpercatinib versus carboplatin or cisplatin and pemetrexed chemotherapy with or without pembrolizumab in treatment-naive patients with locally advanced/metastatic RET fusion-positive nonsquamous non-small-cell lung cancer. The primary end point is progression-free survival by independent review. Key secondary end points include overall survival, response rate, duration of response and progression-free survival. Clinical trial registration: NCT04194944 (ClinicalTrials.gov)

9067 Background: Second-generation (gen) ALK tyrosine kinase inhibitors (TKIs) are standard first- and second-line therapies in patients (pts) with advanced ALK+ non-small cell lung cancer (NSCLC). After progression on second-gen TKI(s), standard options include platinum (PT)-based chemotherapy (chemo) or the third-gen ALK TKI lorlatinib. The efficacy of PT-based chemo is established in treatment-naive pts but is undefined in pts who have failed prior ALK TKIs. Here we evaluate the efficacy of PT/pemetrexed (pem)-based chemo in pts with ALK+ NSCLC refractory to second-gen TKIs. Methods: A retrospective study was performed at three institutions. Pts were eligible if they had advanced ALK+ NSCLC refractory to ≥1 second-gen TKI, and received PT-pem-based chemo. Medical records and imaging were reviewed to determine outcomes. Results: Among 55 eligible pts, chemo regimens included: PT/pem (31/55, 56%), PT/pem/bevacizumab (bev) (6/55, 11%), PT/pem/PD-1 inhibitor (3/55, 5%), PT/pem with ALK TKI (8/55, 15%), PT/pem/bev with TKI (6/55, 11%), and PT/pem/PD-1 inhibitor with TKI (1/55, 2%). Pts had received one (6/55, 11%), two (38/55, 69%), or more (11/55, 20%) prior TKIs. Six pts (11%) previously received adjuvant or neoadjuvant chemo. Radiographic data for response evaluation was available for 39 pts. Among 36 pts with measurable baseline disease, confirmed ORR was 31% (11/36; 95% CI, 16-48%); 13 (36%) had stable disease. The median duration of response was 5.4 months (95% CI, 1.5-7.1 months). The median progression-free survival (PFS) for the entire cohort was 4.0 months (95% CI, 2.8-4.6 months). Chemo (PT/pem +/- bev or PD-1 inhibitor) plus ALK TKI (n = 15) was associated with a significant increase in PFS compared to chemo without TKI (n = 40) (median PFS 6.8 vs 3.2 months; HR 0.306; p = 0.002). Similarly, PT/pem plus ALK TKI (n = 8) was associated with increased PFS compared to PT/pem without TKI (n = 31) (median PFS 6.8 vs 2.9 months; HR 0.358; p = 0.036). Conclusions: The efficacy of PT-pem-based chemo is limited after failure of second-gen ALK TKIs but may be higher in pts who receive chemo plus ALK TKI, suggesting a potential role for ongoing ALK inhibition. The modest benefit of PT-pem-based chemo highlights the need for other therapeutic strategies for pts refractory to second-gen TKIs.

PurposeGemcitabine plus carboplatin (GC) is active as front-line treatment for advanced non–small-cell lung cancer (NSCLC). For patients without progression, timing of second-line chemotherapy for optimum clinical benefit remains uncertain. This phase III, randomized trial assessed the efficacy and safety of docetaxel administered either immediately after GC or at disease progression.Patients and MethodsThe chemotherapy-naïve patients enrolled had either stage IIIB NSCLC with pleural effusion or stage IV NSCLC. Gemcitabine (1,000 mg/m2) was administered on days 1 and 8 followed by carboplatin (area under the curve = 5) on day 1. After four 21-day cycles, patients who did not have progression were randomly assigned either to an immediate docetaxel group (docetaxel 75 mg/m2on day 1 every 21 days, with maximum of six cycles) or to a delayed docetaxel group. The primary end point was overall survival (OS) measured from random assignment. Additional analyses included tumor response, toxicity, progression-free survival (PFS), and quality of life (QOL).ResultsEnrollment totaled 566 patients; 398 patients completed GC; 309 patients were randomly assigned equally to the two docetaxel treatment groups. Toxicity profiles were generally comparable for the docetaxel groups. Median PFS for immediate docetaxel (5.7 months) was significantly greater (P = .0001) than for delayed docetaxel (2.7 months). Median OS for immediate docetaxel (12.3 months) was greater than for delayed docetaxel (9.7 months), but the difference was not statistically significant (P = .0853). QOL results were not statistically different (P = .76) between docetaxel groups.ConclusionWe observed a statistically significant improvement in PFS and a nonstatistically significant increase in OS when docetaxel was administered immediately after front-line GC, without increasing toxicity or decreasing QOL.

3584 Background: Selpercatinib (LOXO-292) is a highly selective and potent small molecule RET kinase inhibitor. Here we report an update on the efficacy and safety of selpercatinib in RET-fusion+ non-small-cell lung cancer (NSCLC). Methods: Patients with RET-fusion+ NSCLC were enrolled to the Phase 1/2 LIBRETTO-001 trial (NCT03157128), a global, multicenter trial (16 countries, 89 sites). Following the Phase 1 dose escalation portion of the trial, patients received the recommended dose of 160 mg orally twice daily. Each cycle was 28 days. The primary endpoint was objective response rate (ORR) per RECIST 1.1. Secondary endpoints included duration of response (DoR) and safety. Per health authority agreement, the primary analysis set was defined as the first 105 consecutively enrolled patients previously treated with platinum-based chemotherapy. Treatment-naïve patients were analyzed separately. All analyses were based on a 16-Dec-2019 data cutoff date. Results: In the primary analysis set of platinum-treated patients (median of 3 prior systemic regimens; range 1-15), the ORR by investigator assessment was 70% (95% CI 59.8–78.1, n = 73/105). Responses did not differ by fusion partner or number or type of prior therapies, including anti-PD-1/PD-L1 agents and off-label multikinase inhibitor use. The median DoR was 20.3 months (95% CI 15.6–24.0) with 45 of 73 (62%) responders censored at a median follow-up of 14.8 months. Among 39 treatment-naïve patients, the ORR by investigator assessment was 90% (95% CI 75.8–97.1, n = 35/39, including 2 responses pending confirmation). Median DoR was not reached with 27 of 33 (82%) confirmed responses ongoing at a median follow-up of 7.4 months. In the safety analysis set consisting of all selpercatinib dosed patients (N = 702), the most common treatment-related adverse events (TRAEs) that occurred in ≥15% of patients were dry mouth (33.3%), increased AST (24.5%), increased ALT (23.8%), hypertension (23.2%), diarrhea (19.7%), and fatigue (16.8%). Only 2% (14 of 702) of patients discontinued selpercatinib for TRAEs. Conclusions: Selpercatinib achieved marked and durable antitumor activity in patients with RET-fusion+ NSCLC. Selpercatinib was well tolerated. Efficacy data assessed by independent review committee based on the 16-Dec-2019 data cutoff date will be presented. Clinical trial information: NCT03157128 .

Introduction: Rearranged during transfection (RET) gene fusions are rare genetic drivers in non-small cell lung cancer (NSCLC). Selective RET-inhibitors such as selpercatinib have shown therapeutic activity in early clinical trials; however, their efficacy in the real-world setting is unknown. Methods: A retrospective efficacy and safety analysis was performed on data from RET fusion-positive NSCLC patients who participated in a selpercatinib access program (named patient protocol) between August 2019 and January 2021. Results: Data from 50 patients with RET fusion-positive advanced NSCLC treated with selpercatinib at 27 centers in 12 countries was analyzed. Most patients were Non-Asian (90%), female (60%), never-smokers (74%), with a median age of 65 years (range, 38–89). 32% of the patients had known brain metastasis at the time of selpercatinib treatment. Overall, 13 patients were treatment-naïve, while 37 were pretreated with a median of three lines of therapy (range, 1–8). The objective response rate (ORR) was 68% [95% confidence interval (CI), 53–81] in the overall population. The disease control rate was 92%. The median progression-free survival was 15.6 months (95% CI, 8.8–22.4) after a median follow-up of 9 months. In patients with measurable brain metastases ( n = 8) intracranial ORR reached 100%. In total, 88% of patients experienced treatment-related adverse events (TRAEs), a large majority of them being grade 1 or 2. The most common grade ⩾ 3 TRAEs were increased liver enzyme levels (in 10% of patients), prolonged QTc time (4%), abdominal pain (4%), hypertension (4%), and fatigue/asthenia (4%). None of patients discontinued selpercatinib treatment for safety reasons. No new safety concerns were observed, nor where there any treatment-related death. Conclusions: In this real-world setting, the selective RET-inhibitor selpercatinib demonstrated durable systemic and intracranial antitumor activity in RET fusion-positive NSCLC and was well tolerated.

Abstract BACKGROUND Brain metastases (BM) are common in non-small cell lung cancer (NSCLC). The aim of this study was to assess the comparative effectiveness of treatments for BM from NSCLC. METHODS We searched MEDLINE, EMBASE, Web of Science, ClinicalTrials.gov, CENTRAL and references of key studies for randomized controlled trials (RCTs) published until October 2018. We also searched the Chinese databases Wanfang Data, Wanfang Med Online, China National Knowledge Infrastructure, and Chongqing VIP Information for RCTs published until September 2019. Trials including &gt; 10 patients were selected. The primary outcomes were overall survival (OS) and intracranial progression-free survival (PFS). We used a frequentist random-effects model for network meta-analysis and assessed the certainty of evidence using the GRADE approach. RESULTS Among 8798 abstracts, 106 RCTs (9452 patients) met inclusion criteria. Median sample size was 67 (range 25-554). All trials included adult patients with histologically proven NSCLC and &gt;1 BM proven on CT/MRI. Of trials that reported performance status (e.g. ECOG or KPS, n=67), 63/67 excluded patients with non-favorable performance status. Interventions assessed included surgery, WBRT, SRS, targeted therapies (i.e. EGFR/ALK inhibitors), and chemotherapy. Compared to WBRT alone, several interventions demonstrated a statistically significant increase in median OS, including non-targeted chemotherapy + surgery (MD: 415.3 days, 95% CI: 31.3-799.4), WBRT + EGFRi (MD: 200.2 days, 95% CI:146.3-254.1), and EGFRi alone (MD: 169.7 days, 95% CI: 49.7-289.7). Among all interventions, only WBRT + EGFRi showed a significant improvement in median PFS (MD: 108.0 days, 95%CI: 48.5-167.5). CONCLUSIONS Our preliminary analyses indicate an OS and PFS benefit on the addition of EGFR inhibitors to WBRT for the treatment of BMs from NSCLC. Further analyses of hazard ratios for OS/PFS are underway, and subgroup analyses are planned. These data support the growing role of targeted therapies in the treatment of BMs, particularly in susceptible mutant tumours.

Background: The Gustave Roussy Immune (GRIm)-Score takes into account neutrophil-to-lymphocyte ratio (NLR), serum albumin concentration and lactate dehydrogenase (LDH) and its prognostic value has been investigated in patients treated with immune check-point inhibitors (ICIs). To further assess the prognostic and predictive value of baseline GRIm-Score (GRImT0) in advanced non-small cell lung cancer (aNSCLC) patients, we separately investigated two cohorts of patients treated with first-line pembrolizumab or chemotherapy. We also investigated whether GRIm-Score at 45 days since treatment initiation (GRImT1) and GRIm-Score difference between the two timepoints may better predict clinical outcomes (GRImΔ = GRImT0 − GRImT1). Methods: We retrospectively evaluated 222 aNSCLC patients: 135 treated with pembrolizumab and 87 treated with chemotherapy as the first-line regimen. NLR, serum albumin and LDH concentrations were assessed at T0 and at T1. According to the GRIm-Score, patients were assigned 1 point if they had NLR > 6, LDH > upper limit normal or albumin < 3.5 g/dL. Patients with a GRIm-Score < 2 were considered as having a low Score. Results: In both cohorts, no difference in terms of overall survival (OS) between patients with low and high GRImT0 was found. Otherwise, median OS and progression free survival (PFS) of the low GRImT1 group were significantly longer than those of the high GRImT1 group in pembrolizumab-treated patients, but not in the CHT cohort (pembrolizumab cohort: low vs. high; median OS not reached vs. 9.2 months, p = 0.004; median PFS 10.8 vs. 2.3 months, p = 0.002). Patients receiving pembrolizumab with stable/positive GRImΔ had better OS (median OS not reached vs. 12.0 months, p < 0.001), PFS (median PFS 20.6 vs. 2.6 months, p < 0.001) and objective response rate (58.2% vs. 7.6%, p = 0.003) compared to patients with negative GRImΔ. Conclusion: Our data shown that GRImT1 and GRImΔ are more reliable peripheral blood biomarkers of outcome compared to GRImT0 in aNSCLC patients treated with pembrolizumab and might represent useful biomarkers to drive clinical decisions in this setting.

Anticancer Effects

Purpose Vorinostat, a histone deacetylase inhibitor, exerts anticancer effects by both histone and nonhistone–mediated mechanisms. It also enhances the anticancer effects of platinum compounds and taxanes in non–small-cell lung cancer (NSCLC) cell lines. This phase II randomized, double-blinded, placebo-controlled study evaluated the efficacy of vorinostat in combination with carboplatin and paclitaxel in patients with advanced-stage NSCLC. Patients and Methods Patients with previously untreated stage IIIB (ie, wet) or IV NSCLC were randomly assigned (2:1) to carboplatin (area under the curve, 6 mg/mL × min) and paclitaxel (200 mg/m2 day 3) with either vorinostat (400 mg by mouth daily) or placebo. Vorinostat or placebo was given on days 1 through 14 of each 3-week cycle to a maximum of six cycles. The primary end point was comparison of the response rate. Results Ninety-four patients initiated protocol therapy. Baseline patient characteristics were similar between the two arms. The median number of cycles was four for both treatment arms. The confirmed response rate was 34% with vorinostat versus 12.5% with placebo (P = .02). There was a trend toward improvement in median progression-free survival (6.0 months v 4.1 months; P = .48) and overall survival (13.0 months v 9.7 months; P = .17) in the vorinostat arm. Grade 4 platelet toxicity was more common with vorinostat (18% v 3%; P < .05). Nausea, emesis, fatigue, dehydration, and hyponatremia also were more frequent with vorinostat. Conclusion Vorinostat enhances the efficacy of carboplatin and paclitaxel in patients with advanced NSCLC. HDAC inhibition is a promising therapeutic strategy for treatment of NSCLC.
