Non Small Cell Lung Cancer (Stage III) Clinical Trial
Official title:
A Phase III, Randomized, Double-blind, Placebo-controlled, Multicenter, International Study of Osimertinib as Maintenance Therapy in Patients With Locally Advanced, Unresectable EGFR Mutation-positive Non-Small Cell Lung Cancer (Stage III) Whose Disease Has Not Progressed Following Definitive Platinum-based Chemoradiation Therapy (LAURA).
A global study to assess the efficacy and safety of osimertinib following chemoradiation in patients with stage III unresectable Epidermal Growth Factor Receptor Mutation Positive non-small cell lung cancer
This is a phase 3 double-blind, randomized, placebo-controlled, study to assess the efficacy and safety of osimertinib following chemoradiation in patients with stage III unresectable EGFR mutation-positive NSCLC, including the most common EGFR sensitising mutations (Ex19Del and L858R), either alone or in combination with other EGFR mutations. Chemoradiation may have been given either given concurrently or sequentially. Patients whose disease has not progressed following chemoradiation will be randomised within 6 weeks of completion of chemoradiation to receive osimertinib or placebo in a 2:1 ratio, and treatment will be continued until disease progression, unacceptable toxicity or other discontinuation criteria are met. After progression, patients can be unblinded and may receive open-label osimertinib. After the final OS analysis, the study blind will be broken and patients still receiving open-label osimertinib will be supplied with open-label osimertinib by AstraZeneca for as long as their treating physician considers they are deriving clinical benefit. ;
