P1.09-011 - LUME-Meso Phase II/III Study: Nintedanib + Pemetrexed/Cisplatin in Chemo-Naïve Patients with Malignant Pleural Mesothelioma (ID 7937)

- Abstract
Background:
Pemetrexed/cisplatin is the standard first-line treatment for unresectable malignant pleural mesothelioma (MPM), with median overall survival (OS) of ~1 year. Nintedanib is a triple angiokinase inhibitor of vascular endothelial growth factor (VEGF) receptors 1–3, platelet-derived growth factor (PDGF) receptors α/β and fibroblast growth factor receptors 1–3. VEGF and PDGF overexpression are associated with poor prognosis in MPM, and nintedanib has demonstrated efficacy in preclinical MPM models. Nintedanib also targets the Src and Abl kinases, which are involved in MPM cell migration. A randomised Phase II trial of nintedanib or placebo + pemetrexed/cisplatin in MPM followed by maintenance nintedanib or placebo, with progression-free survival (PFS) as the primary endpoint, was performed. With regulatory authority guidance, the Phase II data were unblinded. At the primary analysis, PFS benefit was observed with nintedanib, and confirmed at the updated analysis (hazard ratio [HR]=0.54, 95% confidence interval [CI]: 0.33–0.87; p=0.010; median PFS: nintedanib 9.4 months vs placebo 5.7 months). A strong signal towards improved OS also favoured nintedanib (HR=0.77, 95% CI: 0.46–1.29; p=0.319; median OS: 18.3 vs 14.2 months). The study was expanded to include a confirmatory Phase III part based on the primary PFS results, and the Phase II data assisted in planning of the Phase III part, including sample size estimation. Nintedanib was granted US Food and Drug Administration orphan drug designation for the treatment of MPM in December 2016.
Method:
The Phase III part of the study (NCT01907100) is currently recruiting participants. Four hundred and fifty chemotherapy-naïve patients worldwide (~140 sites in 27 countries), aged ≥18 years with unresectable MPM of epithelioid histology and Eastern Cooperative Oncology Group performance score 0–1 will be randomised 1:1 to receive up to six 21-day cycles of pemetrexed (500 mg/m[2])/cisplatin (75 mg/m[2]) on Day 1 + nintedanib or placebo (200 mg twice daily, Days 2–21), followed by nintedanib or placebo monotherapy until disease progression or undue toxicity. The primary endpoint is PFS with the key secondary endpoint being OS. An adaptive design will be used at the time of the primary PFS analysis to reassess the number of OS events for sufficient OS power. Other secondary endpoints are objective response and disease control (using modified Response Evaluation Criteria in Solid Tumors). The frequency and severity of adverse events, as well as health-related quality of life, will also be assessed. An exploratory analysis of predictive/prognostic biomarkers is planned.
