Background: Amivantamab-lazertinib significantly prolonged progression-free survival (PFS) versus osimertinib in patients with epidermal growth factor receptor (EGFR)-mutant advanced non-small-cell lung cancer [NSCLC; hazard ratio (HR) 0.70; P < 0.001], including those with a history of brain metastases (HR 0.69). Patients with TP53 co-mutations, detectable circulating tumor DNA (ctDNA), baseline liver metastases, and those without ctDNA clearance on treatment have poor prognoses. We evaluated outcomes in these high-risk subgroups., Patients and Methods: This analysis included patients with treatment-naive, EGFR-mutant advanced NSCLC randomized to amivantamab-lazertinib (n = 429) or osimertinib (n = 429) in MARIPOSA. Pathogenic alterations were identified by next-generation sequencing (NGS) of baseline blood ctDNA with Guardant360 CDx. Ex19del and L858R ctDNA in blood was analyzed at baseline and cycle 3 day 1 (C3D1) with Biodesix droplet digital polymerase chain reaction (ddPCR)., Results: Baseline ctDNA for NGS of pathogenic alterations was available for 636 patients (amivantamab-lazertinib, n = 320; osimertinib, n = 316). Amivantamab-lazertinib improved median PFS (mPFS) versus osimertinib for patients with TP53 co-mutations {18.2 versus 12.9 months; HR 0.65 [95% confidence interval (CI) 0.48-0.87]; P = 0.003} and for patients with wild-type TP53 [22.1 versus 19.9 months; HR 0.75 (95% CI 0.52-1.07)]. In patients with EGFR-mutant, ddPCR-detectable baseline ctDNA, amivantamab-lazertinib significantly prolonged mPFS versus osimertinib [20.3 versus 14.8 months; HR 0.68 (95% CI 0.53-0.86); P = 0.002]. Amivantamab-lazertinib significantly improved mPFS versus osimertinib in patients without ctDNA clearance at C3D1 [16.5 versus 9.1 months; HR 0.49 (95% CI 0.27-0.87); P = 0.015] and with clearance [24.0 versus 16.5 months; HR 0.64 (95% CI 0.48-0.87); P = 0.004]. Amivantamab-lazertinib significantly prolonged mPFS versus osimertinib among randomized patients with [18.2 versus 11.0 months; HR 0.58 (95% CI 0.37-0.91); P = 0.017] and without baseline liver metastases [24.0 versus 18.3 months; HR 0.74 (95% CI 0.60-0.91); P = 0.004]., Conclusions: Amivantamab-lazertinib effectively overcomes the effect of high-risk features and represents a promising new standard of care for patients with EGFR-mutant advanced NSCLC., (Copyright © 2024 The Author(s).

Background: Human epidermal growth factor receptor 3 (HER3) is broadly expressed in non-small-cell lung cancer (NSCLC) and is the target of patritumab deruxtecan (HER3-DXd), an antibody-drug conjugate consisting of a HER3 antibody attached to a topoisomerase I inhibitor payload via a tetrapeptide-based cleavable linker. U31402-A-U102 is an ongoing phase I study of HER3-DXd in patients with advanced NSCLC. Patients with epidermal growth factor receptor (EGFR)-mutated NSCLC that progressed after EGFR tyrosine kinase inhibitor (TKI) and platinum-based chemotherapy (PBC) who received HER3-DXd 5.6 mg/kg intravenously once every 3 weeks had a confirmed objective response rate (cORR) of 39%. We present median overall survival (OS) with extended follow-up in a larger population of patients with EGFR-mutated NSCLC and an exploratory analysis in those with acquired genomic alterations potentially associated with resistance to HER3-DXd., Patients and Methods: Safety was assessed in patients with EGFR-mutated NSCLC previously treated with EGFR TKI who received HER3-DXd 5.6 mg/kg; efficacy was assessed in those who also had prior PBC., Results: In the safety population (N = 102), median treatment duration was 5.5 (range 0.7-27.5) months. Grade ≥3 adverse events occurred in 76.5% of patients; the overall safety profile was consistent with previous reports. In 78/102 patients who had prior third-generation EGFR TKI and PBC, cORR by blinded independent central review (as per RECIST v1.1) was 41.0% [95% confidence interval (CI) 30.0% to 52.7%], median progression-free survival was 6.4 (95% CI 4.4-10.8) months, and median OS was 16.2 (95% CI 11.2-21.9) months. Patients had diverse mechanisms of EGFR TKI resistance at baseline. At tumor progression, acquired mutations in ERBB3 and TOP1 that might confer resistance to HER3-DXd were identified., Conclusions: In patients with EGFR-mutated NSCLC after EGFR TKI and PBC, HER3-DXd treatment was associated with a clinically meaningful OS. The tumor biomarker characterization comprised the first description of potential mechanisms of resistance to HER3-DXd therapy., Competing Interests: Disclosure HAY has received consulting fees from AstraZeneca, Daiichi Sankyo, Cullinan, Blueprint Medicines, Janssen, Black Diamond, and Takeda.

Objective: The Phase III, randomized, open-label IPASS study (NCT00322452) of first-line epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI) gefitinib versus carboplatin/paclitaxel for Asian patients with advanced non-small-cell lung cancer (NSCLC) showed that investigator-assessed progression-free survival (PFS) and objective response rate (ORR) were significantly prolonged in patients with EGFR mutation-positive NSCLC who received gefitinib versus patients with EGFR mutation-negative NSCLC. We report post-hoc analyses of IPASS data by blind independent central review (BICR), performed at the request of the US FDA, in a subset of patients with EGFR mutation-positive NSCLC., Patients and Methods: Eligible patients (aged ≥18 years; histologically/cytologically confirmed Stage IIB/IV adenocarcinoma NSCLC; non- or former light-smokers; treatment-naïve) were randomly assigned 1:1 to gefitinib (250mg/day) or carboplatin (dose calculated to produce an area under the curve of 5 or 6 mg/mL/minute)/paclitaxel (200mg/m 2 ). Primary endpoint: PFS. BICR analyses included PFS, ORR, and duration of response (DoR)., Results: Scans from 186 IPASS patients (gefitinib n=88, carboplatin/paclitaxel n=98) with EGFR mutation-positive NSCLC were available for BICR. Consistent with investigator-assessed results, in patients with EGFR mutation-positive NSCLC: PFS (hazard ratio 0.54; 95% confidence interval [CI] 0.38, 0.79; p=0.0012) and ORR (odds ratio 3.00; 95% CI 1.63, 5.54; p=0.0004) were significantly longer with gefitinib versus carboplatin/paclitaxel. The median DoR by BICR was 9.6 months with gefitinib and 5.5 months with carboplatin/paclitaxel., Conclusion: BICR analysis of IPASS data support the original, investigator-assessed results. EGFR mutation-positive status remains a significant predictor of response to first-line TKI therapy., (Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.)

Background Preliminary data from TATTON (NCT02143466, a multi-arm, multi-drug combination study) suggested that adding savolitinib (AZD6094, HMPL-504, volitinib), a potent and highly selective MET TKI, to osimertinib, a 3rd generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI), which selectively inhibits EGFR TKI sensitising (EGFRm) and T790M resistance mutations, may overcome MET-driven resistance to EGFR TKIs. We present updated data from TATTON Part B and data from Part D, for the first time. Methods Pts were ≥18 years (Japan ≥20 years), mainly Asian, with locally advanced/metastatic, MET-positive, EGFRm NSCLC and disease progression on prior therapy. Pts enrolled based on MET status by local fluorescent in-situ hybridisation (MET gene copy ≥5 or MET/CEP7 ratio ≥2), next-generation sequencing or immunohistochemistry (+3 in ≥ 50% of tumour cells), with retrospective central confirmation. Pts in Part B received osimertinib 80 mg + savolitinib 600 mg or 300 mg orally (PO) once daily (QD). Pts in Part D received osimertinib 80 mg + savolitinib 300 mg PO QD, were T790M negative and had received no prior 3rd generation EGFR TKI. Primary endpoints: safety and tolerability; secondary endpoints included objective response rate and progression-free survival. Results In Parts B (N = 138) and D (N = 42); Grade ≥3 AEs reported by 57% and 38%, respectively; serious AEs reported by 45% and 26%, respectively. AEs possibly related to treatment, led to discontinuation of savolitinib in 38 (28%) vs 9 (21%) and osimertinib in 14 (10%) vs 2 (5%), for Parts B and D, respectively. Efficacy data: Table.

[ABSTRACT FROM AUTHOR]

Background Pembrolizumab, a PD-1 inhibitor combined with platinum-based Ctx is standard therapy for eligible pts without a targetable mutation, stage IIIB/IV NSCLC. Currently, there is no data to guide treatment following progression on sequential/concomitant use of platinum-based Ctx and PD-1 inhibitors. Activation of inflammation and elevated baseline c-reactive protein (CRP) levels are associated with a lower response to immunotherapies. Canakinumab is a high-affinity anti-IL-1β monoclonal antibody that showed a significant reduction in the incidence of fatal and nonfatal lung cancer in myocardial infarction pts with increased CRP levels (CANTOS study). Trial design CANOPY-2 (NCT03626545) is a multicenter, phase 3 study evaluating the safety and efficacy of docetaxel ± canakinumab in pts with squamous/non-squamous, stage IIIB-IV NSCLC. This study includes a safety run-in part (part 1 – open-label) to confirm recommended phase 3 regimen (RP3R) to be used in the randomized phase 3 part (part 2 – double-blind, placebo-controlled). Key inclusion criteria: adult pts pretreated with one prior platinum-based Ctx and one prior PD-(L)1 inhibitor therapy for locally advanced or metastatic disease, either together/sequentially and then progressed; ECOG PS 0-1. In part 1, ∼9 pts will be enrolled to have at least 6 evaluable pts and ∼226 pts will be randomized (1:1, stratified by the number of prior lines of therapy and histology) in part 2 to docetaxel ± canakinumab. Primary objectives: to confirm RP3R of canakinumab + docetaxel, as determined by the incidence of dose-limiting toxicity in the first 42 days of administration (part 1) and overall survival (part 2). Secondary objectives: overall response rate, disease control rate, duration of response, time to response, progression-free survival by investigator (RECIST v1.1), safety, PK, immunogenicity of canakinumab, and patient-reported outcomes. Part 1 is completed and part 2 is ongoing after confirming canakinumab 300 mg Q3W as RP3R. Clinical trial identification ACZ885V2301/NCT03626545. Legal entity responsible for the study Novartis.

Background Identifying the optimal sequence of EGFR TKIs is important to maximise survival in EGFR mutation-positive (EGFRm+) NSCLC. The observational GioTag study (NCT03370770) investigated outcomes in patients (pts) with EGFRm+ NSCLC who were treated with sequential afatinib and osimertinib in a 'real-world' clinical setting, including pts with poor prognosis (ECOG PS ≥ 2: 15%; stable brain metastases: 10%).1 In the primary analysis, time to treatment failure (TTF) was 27.6 months in the overall population, 30.3 months in Del19-positive pts, and 46.7 months in Asians. Here we report overall survival (OS) and updated TTF. Methods Data were retrospectively collected from Dec 2017–June 2018 for 203 pts with EGFRm + (Del19, L858R) NSCLC who were T790M positive after first-line afatinib and subsequently received osimertinib. TTF was the primary outcome; OS analysis was exploratory. Data were collected from electronic health records (EHRs; n = 126) or medical charts (n = 77). For logistical reasons, this interim analysis includes updated data (at April 2019) from pts with available EHRs (all USA; n = 94); final analysis with updated data from manual chart reviews is anticipated in early 2020. Results After median follow-up of 30.3 months, median OS was 41.3 months (90% CI: 36.8–46.3) in the overall dataset (n = 203) and 45.7 months (90% CI: 45.3–51.5) in Del19-positive pts (n = 149); 2-year OS was 80%. OS in Asians was immature. Updated median TTF was 28.1 months (90% CI: 26.8–30.3) in all pts, and 30.6 months (90% CI: 27.6–32.0) in Del19-positive pts. Median TTF with osimertinib was 15.6 months (90% CI: 13.8–17.1) in the overall dataset, and 16.4 months (90% CI: 14.9–17.9) in Del19-positive pts. Median time from osimertinib discontinuation to death was 8 months. In 168 pts starting on afatinib 40 mg, median OS was 45.3 months (90% CI: 37.6–47.6); median TTF was 28.1 months (90% CI: 26.8–30.6). Conclusions Encouraging OS and TTF was seen in pts with EGFR T790M-positive NSCLC with sequential afatinib and osimertinib, especially Del19-positive pts. Of note, prior afatinib treatment did not preclude prolonged TTF with second-line osimertinib. 1. Hochmair MJ, et al. Future Oncol. 2018;14:2861–74. Clinical trial identification NCT03370770.

Background There is an expanding list of therapeutically relevant biomarkers for NSCLC and effective molecular profiling is paramount. We sought to comprehensively and prospectively evaluate the molecular epidemiology of NSCLC in Asia and ascertain the extent of access to relevant therapies. The study is being conducted by the Asian Thoracic Oncology Research Group (ATORG) – an academic co-operative lung cancer trials group in Asia. Methods ATORG-001 is a prospective, multi-centre study of NSCLC patients (pts) throughout Asia. Eligible pts must have good performance status (ECOG ≤2), adequate organ function and ≤3 prior lines of cytotoxic chemotherapy. Archival tissue specimens are sent to a central laboratory in Singapore (Singapore General Hospital) for profiling, consisting of NGS with the Oncomine Focus Assay (52 gene panel including fusions) and PD-L1 immunohistochemistry. Results are returned to investigators in a clinically relevant timeframe. Baseline demographics, pre-existing molecular profile and prior treatment details are collected. Treatment and pt outcomes are followed for 2 years. Recruitment commenced in Jan 2019 in 3 sites (National Cancer Centre Singapore, Chinese University of Hong Kong, University Malaya Medical Centre). We report an interim analysis for the first 27 of a planned 500 pts. Results As of 01 Jul 2019, 27 pts have enrolled with median age 67 yrs (range 46-79), 59% male, 81% adenocarcinoma, 52% stage IV, 37% non-smokers, median lines of prior therapy 1 (range 0-6) and 85% with no known oncogenic driver. Pre-existing mutation status was known in 89% for EGFR and 63% for ALK. Median turnaround time from tissue acquisition to profiling results was 22 days (range 15-74). New alterations were most common in KRAS (19%), MYC (15%), CDK4 (7%) and ERBB2 (7%). Potentially actionable new alterations were found in 7 (26%) pts, including KRAS G12C mutation (7%), BRAF G469A mutation (4%), ERBB2 exon 20 insertion (4%), ERBB2 amplification (4%), FGFR2 amplification (4%) and MET exon 14 skipping mutation (4%). Conclusions Enrolment is ongoing with additional sites and countries planned to comprehensively evaluate the molecular epidemiology of NSCLC in Asia.
