Abstract
9594 Background: IMpower110 (NCT02409342) evaluated atezo (anti–PD-L1) monotherapy as 1L treatment in PD-L1–selected patients (pts) with metastatic NSCLC and met its primary endpoint with statistically significant and clinically meaningful OS benefit in TC3 or IC3 wild-type (WT; EGFR/ALK-negative) pts. PROs were prespecified endpoints to assess pt perspectives on overall clinical benefit. Methods: Pts were randomized 1:1 to receive atezo 1200 mg IV q3w (Arm A) or platinum-based chemo (Arm B; 4 or 6 21-day cycles). Arm B non-squamous pts received cisplatin (cis) 75 mg/m2 or carboplatin (carbo) AUC 6 + pemetrexed 500 mg/m2 IV q3w; Arm B squamous pts received cis 75 mg/m2 + gemcitabine (gem) 1250 mg/m2 or carbo AUC 5 + gem 1000 mg/m2 IV q3w. PROs were assessed by the EORTC Quality of Life Questionnaire Core 30 (QLQ-C30) and lung cancer module QLQ-LC13. Time to confirmed deterioration (TTD) in QLQ-LC13 lung cancer symptoms (secondary endpoint) and change from baseline (BL) in global health status (GHS), functioning and lung cancer symptoms (exploratory endpoints) were analyzed in TC3 or IC3-WT pts. Clinically meaningful change was defined as a ≥10-point deterioration from BL. Results: Completion rates at BL (atezo, n = 107; chemo, n = 98) were high in both arms for the QLC-C30 (90% atezo, 86% chemo) and the QLC-LC13 (89% atezo, 85% chemo), and remained > 80% at most visits. Mean BL scores for GHS, physical functioning, and role functioning were moderate, symptom burden was low, and all were similar in both arms. No differences in TTD were seen between arms for cough (HR, 0.98; 95% CI: 0.48, 2.03), chest pain (HR, 1.02; 95% CI: 0.47, 2.22), dyspnea (HR, 0.96, 95% CI: 0.57, 1.60), and 3-symptom composite score (HR, 0.92; 95% CI: 0.59, 1.44). Mean change in physical function from BL to wk 42 was modestly improved with atezo and greater than or similar to chemo. No clinically meaningful worsening in dyspnea, cough or chest pain was seen with atezo vs chemo. Mean change in cough and chest pain from BL numerically improved immediately after start of treatment and was maintained to wk 48 with atezo. Fatigue and nausea/vomiting scores numerically improved immediately with atezo and were maintained to wk 48. Conclusions: QLQ-C30 and QLQ-LC13 completion rates were high at BL and most study visits. TTD of lung cancer-related symptoms was similar in both arms, indicating pts’ low BL symptom burden was maintained for a similar duration. Pts receiving atezo vs chemo sustained numerical improvements in physical function and no worsening in lung cancer-related symptoms. Clinical trial information: NCT02409342 .

Abstract
TPS9597 Background: Uveal melanoma (UM) is a rare subtype of melanoma with no effective therapy for advanced disease. UM is characterized by mutations in GNAQ and GNA11 leading to constitutive activation of the mitogen activated protein kinase (MAPK) pathway. We have previously shown that targeting the MAPK pathway though MEK inhibition with Selumetinib (AZD6244, ARRY-142886) using a continuous dosing schedule improved progression free survival (PFS) in a randomized Phase II study of Selumetininb versus chemotherapy in patients with metastatic UM; however, no PFS or overall survival (OS) benefit was observed in a subsequent randomized Phase III study of Selumetinib and chemotherapy versus chemotherapy alone. We hypothesize that an intermittent dosing schedule of Selumetinib may be more effective than continuous dosing by achieving higher dose levels, better drug tolerability, and more complete target inhibition. We propose a Phase Ib study of Selumetinib in UM using an intermittent dosing schedule. Methods: A total of 28 subjects will be enrolled using the time to event continual reassessment method (TITE-CRM). Key inclusion criteria include a diagnosis of advanced UM, measurable disease by RECIST v1.1, and no prior MEK inhibitor therapy. Eligible subjects will be treated with Selumetinib starting at a dose level of 125 mg orally twice a day, using a 3-days-on and 4-days-off per week schedule. The primary goal of this study is to estimate the maximum tolerated dose (MTD) of intermittently dosed Selumetinib. Secondary endpoints are response rate, PFS and OS. Responses will be evaluated every 8 weeks by a CT scan of the chest and CT or MRI of the abdomen/ pelvis using RECIST v1.1 criteria. Mandatory tumor biopsies will be obtained at baseline, cycle 1 day 3 (Selumetinib-on day), and between cycle 1 day 11-14 (Selumetinib-off day) in 20 subjects, and optionally at progression. Tumor tissue will be assessed for MAPK pathway inhibition and reactivation at each time point, as well as mechanisms of resistance. Recruitment is currently ongoing. Clinical trial information: NCT02768766.
