e18078 Background: First-line treatment of advanced nonsquamous non-small cell lung cancer (NSCLC) with platinum-based doublets, including pemetrexed (P) or bevacizumab (B), has achieved more than 12 months of survival. At the moment, there are no phase III head-to-head comparisons of these combinations. Methods: We retrospectively analyzed, from 05/2007 to 02/2011, in a single institution, all pts with stage IIIB or IV nonsquamous NSCLC treated with B or P combined with platinum compounds in first-line treatment to determine differences in OS, PFS, ORR and toxicity. We performed multivariate analysis to identify prognostic factors for survival. Results: Of the 82 pts included, 40 pts (48,8%) received carboplatin/paclitaxel or cisplatin/gemcitabine combined with B (BEV group), while 42 pts (51,2%) received cisplatin or carboplatin combined with P (PEM group). BEV had significantly fewer pts with age > 70 years (p=0,01) and CNS metastases (p<0,001) than PEM. Maintenance therapy was administered in 65,0% and 52,4% of pts in BEV and PEM groups, respectively (p=0,17). Significantly more pts in BEV received second-line treatment (72,5% vs. 52,4%; p=0,04) than in PEM, prevailing P as drug of choice (79,3%). ORR (60,0% vs. 35,7%; p=0,04) and median survival (26,4 vs. 16,4 months; p=0,009) were significantly superior for BEV. Median PFS were not different between BEV and PEM (10,5 vs. 7,7 months; p=0,06). In multivariate analysis, ECOG 2 (p=0,005), bone (p=0,01) and adrenal metastases (p=0,005) were independent prognostic factors for worst survival, while treatment with BEV did not reach statistical significance (p=0,07). Grade 3-4 neutropenia (27,5% vs. 9,5%; p=0,03) and neuropathy (17,5% vs. 0%;p=0,005) were more frequent in BEV. Conclusions: First-line treatment of advanced nonsquamous NSCLC patients with platinum-based doublets combined with B resulted in better ORR and higher rate of toxic effects as compared with P-based regimens. ECOG 2, bone and adrenal metastases were independent prognostic factors for poor survival. Although there was a survival benefit at univariate analysis, use of B combination was not an independent prognostic fator.

Background: Molecular diagnostic testing is necessary to guide optimal first-line treatment. The number of patients who receive first-line treatment based on biomarker analysis in Japan is unknown. We aimed to determine the proportion of nonsquamous non-small cell lung cancer (NSCLC) patients for whom first-line treatment was selected based on biomarker testing. Methods: This retrospective, multicenter, observational study registered patients aged ⩾20 years with locally advanced or metastatic nonsquamous NSCLC who started first-line treatment between August and December 2017 in Japan. Data were collected from medical records between January and May 2018. The primary endpoint was the proportion of patients with confirmed biomarker status for first-line treatment decision. Results: Among 202 patients enrolled from 11 centers, 161 (79.7%; 95% confidence interval, 74.2–85.2%) had confirmed biomarker status. The testing rate was highest for epidermal growth factor receptor ( EGFR; 97.5%), followed by anaplastic lymphoma kinase ( ALK; 88.1%), programmed death ligand-1 (PD-L1; 87.1%), and ROS1 (67.3%). For first-line treatment, 70/75 patients with EGFR-positive tumors were administered an EGFR-TKI; 14/15 patients with ALK-positive tumors received an ALK inhibitor; 2/2 patients with ROS1-positive tumors received a ROS1 inhibitor; and 29/36 driver mutation-negative patients with a PD-L1 tumor proportion score ⩾50% were administered an anti-PD-1 monoclonal antibody. Median times from confirmed diagnosis date to first-line treatment initiation, and from first biomarker test order to last biomarker test result were 19 and 11 days, respectively. Conclusions: The proportion of nonsquamous NSCLC patients with confirmed biomarker status for first-line treatment was considered insufficient and in need of improvement.

BackgroundThe phase III DANUBE study assessed the efficacy of the PD-L1 inhibitor durvalumab (D), alone or in combination with the CTLA-4 inhibitor tremelimumab (T), versus standard of care chemotherapy (SoC) for the first-line treatment of unresectable, locally advanced or metastatic UC. The study did not meet its co-primary endpoints of improving overall survival (OS) for D monotherapy vs SoC in patients with high tumor PD-L1 expression or for D+T vs SoC in the intention-to-treat population.1 TMB measurement in blood (bTMB) or tumour (tTMB) has been linked to improved efficacy with PD-1/PD-L1 inhibitors in UC and with D+T in non-small cell lung cancer,2 thus providing a rationale to explore TMB in the DANUBE trial.MethodsBaseline plasma samples from DANUBE were assessed for bTMB using the Guardant OMNI platform, while baseline tTMB was measured in formalin-fixed paraffin-embedded (FFPE) tumour samples using the FoundationOne CDx gene panel. Associations between progression-free survival (PFS) and median and landmark OS with bTMB and tTMB levels at various cutoffs were assessed as part of a pre-specified exploratory analysis. The data cutoff occurred on January 27, 2020.ResultsAmong 1032 patients randomised in DANUBE, 536 (51.9%) were evaluable for bTMB and 623 (60.4%) were evaluable for tTMB. For D vs SoC, bTMB and tTMB were not associated with OS or PFS at any cutoff. For D+T, stronger associations between bTMB and OS as well as PFS were observed with increasing bTMB cutoffs (table 1). At the bTMB cutoff ≥ 24 mut/Mb, 12-month OS rates were 76.7% for D+T and 54.3% for SoC, whereas for bTMB < 24 mut/Mb, 12-month OS rates were 53.4% for D+T and 51.2% for SoC. Similar trends for both OS and PFS were observed with tTMB (table 1).Abstract 266 Table 1Association between TMB and survival outcomes with D+TAssociation between TMB and survival outcomes with D+TConclusionsBoth bTMB and tTMB are potentially useful biomarkers for enriching responses to D+T in previously untreated, advanced UC. Neither bTMB nor tTMB was associated with better outcomes for D monotherapy. Cutoffs of 24 mut/Mb for bTMB and 10 mut/Mb for tTMB appear optimal for D+T in the setting of previously untreated, advanced UC.Trial RegistrationThe trial is registered with ClinicalTrials.gov, NCT02516241, and the EU Clinical Trials Register, EudraCT number 2015-001633-24.ReferencesAstraZeneca.
