Clinical Trial 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.

7. Females should be using adequate contraceptive measures and must have a negative pregnancy test prior to start of dosing if of child-bearing potential, or must have evidence of non-child-bearing potential by fulfilling one of the following criteria at screening: Post-menopausal defined as aged more than 50 years and amenorrhoeic for at least 12 months following cessation of all exogenous hormonal treatments. Women under 50 years old would be considered post-menopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatments and with LH and FSH levels in the post-menopausal range for the institution. Documentation of irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but not tubal ligation.
