A Phase I, Open-Label, Non-Randomised, Multicentre Study to Assess the Effect of Rifampicin (a CYP3A4 Inducer) on the Pharmacokinetics of AZD9291 in Patients With EGFRm Positive NSCLC Whose Disease Has Progressed on an EGFR TKI
In Brief
A Phase 1 clinical trial evaluating Pharmacokinetic sampling - AZD9291, Rifampicin, and 3 other interventions for Non Small Cell Lung Cancer. Completed, enrolled 41 participants across 18 sites in 6 countries.
Detailed Summary
This is a Phase I, open-label, 2-part study in patients with a confirmed diagnosis of epidermal growth factor receptor (EGFR) mutation positive (EGFRm+) non-small cell lung cancer (NSCLC), who have progressed following prior therapy with an approved EGFR tyrosine kinase inhibitor (TKI) agent. Part A will assess the effect of rifampicin on the pharmacokinetic (PK) parameters of AZD9291 and metabolites AZ5104 and AZ7550 following multiple oral dosing of both rifampicin and AZD9291 in a fasted state. Part B will allow patients further access to AZD9291 after the PK phase (Part A) and will provide for additional safety data collection. All patients who complete Part A will be able to enter part B, and continue to receive AZD9291 80 mg once daily until: disease progression; they are no longer deriving clinical benefit; or any other reason.
