Randomised, multicentre, phase III, open-label study of alectinib vs crizotinib in treatment-naïve anaplastic lymphoma kinase (ALK)-positive advanced NSCLC (ALEX study).
Background: In ∼5% of advanced NSCLC tumours, ALK tyrosine kinase is constitutively activated after translocation of ALK. ALK+ NSCLC was shown to be highly sensitive to the first approved ALK inhibitor, crizotinib. However, all pts eventually relapse on crizotinib mainly due to secondary ALK mutations/amplification or CNS metastases. Alectinib is a highly selective, potent, oral next-generation ALK inhibitor. Clinical phase II alectinib data in 46 crizotinib-naïve pts with ALK+ NSCLC reported an objective response rate (ORR) of 93.5% and a 1-year progression-free rate of 83% (95% CI: 68-92) (Inoue et al. J Thorac Oncol 2013). CNS activity was seen: of 14 pts with baseline brain metastasis, 11 had prior CNS radiation, 9 of these experienced CNS and systemic PFS of >12 months; of the 3 pts without prior CNS radiation, 2 were >15 months progression free.
Trial design: Randomised, multicentre, phase III, open-label study in pts with treatment-naïve ALK+ advanced, recurrent, or metastatic NSCLC. All pts must provide pretreatment tumour tissue to confirm ALK rearrangement (by IHC). Pts (∼286 from ∼180 centres, ∼30 countries worldwide) will be randomised to alectinib (600mg oral bid, with food) or crizotinib (250mg oral bid, with/without food) until disease progression (PD), unacceptable toxicity, withdrawal of consent, or death. Stratification factors are: ECOG PS (0/1 vs 2), race (Asian vs non-Asian), baseline CNS metastases (yes vs no). Primary endpoint: PFS by investigators (RECIST v1.1). Secondary endpoints: PFS by Independent Review Committee (IRC); ORR; duration of response; OS; safety; pharmacokinetics; quality of life. Additionally, time to CNS progression will be evaluated (MRI) for the first time in a prospective randomised NSCLC trial as a secondary endpoint. Pts with isolated asymptomatic CNS progression will be allowed to continue treatment beyond documented progression until systemic PD and/or symptomatic CNS progression, according to investigator opinion. Time to CNS progression will be retrospectively assessed by the IRC using two separate criteria, RECIST and RANO. Further details: ClinicalTrials.gov (NCT02075840).

158P Afatinib in patients with EGFR mutation-positive (EGFRm+) NSCLC harbouring uncommon mutations: Overview of clinical data
Immune checkpoint inhibitors plus chemotherapy versus chemotherapy or immunotherapy for first-line treatment of advanced non-small cell lung cancer: A generic protocol
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To determine the effectiveness and toxicity of immune checkpoint inhibitors plus chemotherapy versus chemotherapy or immunotherapy alone as first-line treatment of advanced non-small cell lung cancer (NSCLC). © 2018 The Cochrane Collaboration

KRYSTAL-1: Activity and preliminary pharmacodynamic (PD) analysis of adagrasib (MRTX849) in patients (Pts) with advanced non-small cell lung cancer (NSCLC) harboring KRASG12C mutation
Background: KRAS, the most frequently mutated oncogene in cancer, is a key mediator of the RAS/MAPK signaling cascade that promotes cellular growth and proliferation. KRASG12C mutations occur in approximately 14% of NSCLC (adenocarcinoma). Adagrasib, an investigational agent, is a potent, covalent inhibitor of KRASG12C that irreversibly and selectively binds to KRASG12C, locking it in its inactive state and was optimized for favorable PK properties, including oral bioavailability, long half-life (∼24 h), and extensive tissue distribution.
Methods: KRYSTAL-1 (NCT03785249) is a multi-cohort phase I/II study evaluating adagrasib in pts with advanced or metastatic solid tumors, including NSCLC, harboring a KRASG12C mutation previously treated with chemotherapy and an anti-PD-(L)1. Exploratory endpoints include correlative analysis of co-occurring genetic alterations in tumor tissue at baseline and evaluation of the modulation of PD markers, including transcriptomics, in pretreatment and on-study biopsies.
Results: As of 30 August 2020, 79 pts with pretreated NSCLC were treated with adagrasib 600 mg BID (phase I/Ib and phase II). Most commonly reported (\u3e20%) TRAEs included: nausea (54%), diarrhea (48%), vomiting (34%), fatigue (28%), and increased ALT (23%). Among the 51 pts evaluable for clinical activity, 45% (23/51) had a partial response (PR) and 26 pts had stable disease (SD). In a subpopulation of pts with STK11-comutations, ORR was 64% (9/14). Preliminary PD and mechanistic biomarker analyses on pre- and posttreatment tumor NSCLC biopsies (n = 3) demonstrate own regulation of KRAS/MAPK pathway genes including DUSP6 and SPRY4. In pts with tumors harboring STK11-comutations, there was minimal expression of immune transcripts (eg, CD4 and CD8) at baseline and these transcripts were increased after treatment with adagrasib suggesting a potential immune response to therapy.
Conclusions: Adagrasib is tolerable and has demonstrated clinical activity in pts with previously treated KRASG12C-mutant NSCLC. Additional PD and mechanistic data will be presented
EP08.02-041 NVL-520, a Highly Selective ROS1 Inhibitor, in Patients with Advanced ROS1-Positive Solid Tumors: The Phase 1/2 ARROS-1 Study
Introduction: Oncogenic ROS1 gene fusions are implicated in the pathogenesis of various adult and pediatric cancers, including up to 3% of non-small cell lung cancers (NSCLC), where up to 40% of patients present with central nervous system (CNS) metastases. Tyrosine kinase inhibitors (TKIs) approved by the FDA and EMA for ROS1-positive NSCLC (crizotinib and entrectinib) are limited by acquired resistance, frequently mediated by secondary ROS1 kinase domain mutations. In addition, dual TRK/ROS1 kinase inhibitors such as entrectinib are associated with neurologic adverse events. NVL-520 is a novel, brain-penetrant ROS1-selective kinase inhibitor that exhibits preclinical activity against a diverse array of ROS1 fusions and ROS1 mutations including G2032R, while sparing inhibition of TRK. The ARROS-1 study evaluates the safety and activity of NVL-520 in patients with solid tumors harboring ROS1 fusions, including those with ROS1 resistance mutations and CNS metastases.
Methods: ARROS-1 (NCT05118789) consists of a phase 1 dose escalation, followed by phase 2 expansion in cohorts defined by tumor type and prior therapies that are designed to support potential registration. Phase 1 includes adult patients with any solid tumor type harboring a ROS1 gene fusion (by local testing), with evaluable disease, who have received ≥ 1 prior ROS1 TKI. Prior platinum-based chemotherapies and/or immunotherapies, as well as stable CNS disease, are allowed. Patients will receive NVL-520 by daily oral administration. Primary phase 1 objectives are to determine the NVL-520 recommended phase 2 dose, and, if applicable, maximum tolerated dose. Additional objectives include evaluation of safety/tolerability, preliminary activity, and characterization of the pharmacokinetic and pharmacodynamic profiles of NVL-520. Longitudinal analysis of circulating tumor DNA will be performed, including ROS1 mutation profiling and other relevant biomarkers. The phase 1 portion of the study is ongoing.
