P3.01-080 - An Open-Label, Multicenter, Phase 1b/2 Study to Evaluate Necitumumab in Combination with Gemcitabine and Cisplatin in the First-Line Treatment of Patients with Advanced (Stage IV) Squamous Non-Small Cell Lung Cancer (NSCLC) (ID 184)

- Abstract
Background:
Necitumumab (N) is a human IgG1 anti-epidermal growth factor receptor (EGFR) monoclonal antibody. Squamous (SQ) histology accounts for 25-30% of non-small cell lung cancer (NSCLC) and gemcitabine combined with cisplatin (GC) is a standard of care for advanced or metastatic SQ-NSCLC. In the previous global randomized, open-label, Phase 3 trial (SQUIRE), compared with GC, the addition of N to GC (GC+N) significantly improved overall survival (OS) (HR=0.84, p=0.012; median 11.5 vs 9.9 months) and progression-free survival (PFS) (HR=0.85, p=0.020; median 5.7 vs 5.5 months). The objective response rate (ORR) was 31% vs 29% (p=0.400), and the disease control rate (DCR) was 82% vs 77% (p=0.043), respectively. The SQUIRE results were an important advance in the search for a new treatment for patients with metastatic SQ-NSCLC, where limited progress has been made over the last two decades. However, only 8% of patients in SQUIRE Trial were Asian and no Japanese institutions participated. We have therefore conducted this Phase 1b/2 trial to evaluate the efficacy and safety of GC+N in Japanese patients with advanced SQ-NSCLC.
Methods:
This trial consists of a Phase 1b and Phase 2 part. Patients with advanced (Stage IV) SQ-NSCLC are eligible for enrollment if they are aged³20 years with an Eastern Cooperative Oncology Group performance status (ECOG PS) 0 or 1; measurable or nonmeasurable disease according to Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.0; adequate organ function. GC+N or GC may continue for a maximum of 4 cycles; patients with at least stable disease in GC+N may continue to receive N until disease progression or emerging non-acceptable toxicity. The purpose of Phase 1b part is to determine the recommended dose of the combination of GC (G=1000 or 1250 mg/m[2] iv, Days 1 and 8; C=75 mg/m[2] iv, Day 1; 3-week cycle) and N (800 mg iv, Days 1 and 8; 3-week cycle). Patients are enrolled in 2 cohorts using a conventional 3+3 study design, with dose-escalation of gemcitabine permitted according to the incidence of dose-limiting toxicity (DLT). The Phase 2 part is an open-label, randomized trial to evaluate the efficacy and safety of addition of N to GC. Patients are randomly assigned on a 1:1 basis (Stratification factors: ECOG PS and gender) to GC+N (Arm A) or GC (Arm B). The primary endpoint is OS for which the final analysis will be performed when at least 137 events are observed. The sample size of 180 patients (137 events) has 68% power for a log-rank test at 0.2 one-sided alpha. The secondary endpoints include PFS, ORR, time to treatment failure, Pharmacokinetics, safety and patient-reported outcomes. The relationship between EGFR protein expression level by immunohistochemistry (IHC) and each of several efficacy measures will also be assessed. Translational research analyses will be performed to analyze relevant biomarkers for clinical outcomes. ClinicalTrial.gov Identifier: NCT01763788.
