    Until 90 days after the last dose of study treatment

Study Arms (1)

Osimertinib

EXPERIMENTAL

Participants will receive Osimertinib

Drug: Osimertinib

Interventions

  • Patients should be using adequate contraceptive measures.

You may not qualify if:

  • Ongoing, unresolved, Grade 3 or above toxicity requiring interruption of treatment at the time of the termination of the parent study.
  • Currently receiving treatment with any prohibited medication(s).
  • Concurrently enrolled in any other type of medical research judged not to be scientifically, or medically compatible with this study.
  • Permanent discontinuation from the parent study due to toxicity or disease progression.
  • Local access to commercially-available drug at no cost to the patient is permitted by local regulation.
  • \. Active infection including active hepatitis C and Human immunodeficiency virus (HIV) infection or active uncontrolled Hepatitis B virus (HBV) infection. Screening for chronic conditions is not required.
  • Patients with HBV infection are only eligible if they meet all the following criteria:
  • Demonstrated absence of HCV co-infection or history of HCV co-infection;
  • Demonstrated absence of HIV infection;
  • Patients receiving anti-viral treatment for at least 6 weeks prior to study treatment, HBV DNA is suppressed to \< 100 IU/mL, and transaminase levels are below ULN.
  • Patients with a resolved or chronic HBV infection are eligible if they are:
  • Negative for HBsAg and positive for anti-HBc IgG. In addition, patients must be receiving anti-viral prophylaxis for 2 to 4 weeks prior to study treatment and 6 to 12 months (to be determined by hepatologist) post treatment; or
  • Positive for HBsAg, but for \> 6 months have had transaminases levels below ULN and HBV DNA levels below \< 100 IU/mL (ie, patients are in an inactive carrier state). In addition, patients must be receiving anti-viral prophylaxis for 2 to 4 weeks prior to study treatment.
  • Should participants with HIV infection be included, patients are only eligible if they meet all the following criteria:
  • Undetectable viral RNA load for 6 months
  • +3 more criteria
