A Global Study to Assess the Effects of Osimertinib Following Chemoradiation in Patients With Stage III Unresectable Non-small Cell Lung Cancer (LAURA) (LAURA)

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

Study Overview

• Status: Active, not recruiting
• Conditions: Non Small Cell Lung Cancer (Stage III)
• Intervention / Treatment: Drug: Osimertinib 80mg/40mg; Drug: Placebo Osimertinib 80mg/40mg

Detailed Description

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.

   • Mean resting corrected QT interval (QTc) >470 msec, obtained from 3 ECGs
   • Any clinically important abnormalities in rhythm, conduction, or morphology of resting ECG
   • Patient with any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first-degree relatives or any concomitant medication known to prolong the QT interval and cause Torsades de Pointes
6. Inadequate bone marrow reserve or organ function
7. History of other malignancies, except: adequately treated non-melanoma skin cancer or lentigo maligna , curatively treated in-situ cancer, or other solid tumors curatively treated with no evidence of disease for > 5 years following the end of treatment and which, in the opinion of the treating physician, do not have a substantial risk of recurrence of the prior malignancy.
8. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension and active bleeding diatheses; or active infection including hepatitis B, hepatitis C and human immunodeficiency virus (HIV).
9. Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of osimertinib
10. Prior treatment with any prior chemotherapy, radiation therapy, immunotherapy or investigational agents for NSCLC outside of that received in the definitive setting for Stage III disease (chemotherapy and radiotherapy in SCRT and CCRT regimens is allowed for treatment of Stage III disease).
11. Prior treatment with EGFR-TKI therapy
12. Major surgery as defined by the investigator within 4 weeks of the first dose of study drug.
13. Patients currently receiving (unable to stop use prior to receiving the first dose of study treatment) medications or herbal supplements known to be strong inducers of CYP3A4 (at least 3 weeks prior to receiving the first dose of study drug).
14. Contraindication to MRI, including but not limited to, claustrophobia, pace makers, metal implants, intracranial surgical clips and metal foreign bodies

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free survival (PFS)	Defined as the time from randomisation until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomised therapy or receives another anti-cancer therapy prior to progression, based on blinded independent central review assessment according to RECIST 1.1	Approximately 13 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
PFS in patients with EGFR Ex19del or L858R mutation	Defined as the time from randomisation until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomised therapy or receives another anti-cancer therapy prior to progression.' based on blinded independent central review assessment according to RECIST 1.1	Approximately 13 months
PFS in patients with EGFR mutations Ex19del or L858R detectable in plasma-derived ctDNA	Defined as the time from randomisation until the date of objective disease progression or death (by any cause in the absence of progression) regardless of whether the patient withdraws from randomised therapy or receives another anti-cancer therapy prior to progression.' based on blinded independent central review assessment according to RECIST 1.1	Approximately 13 months
