- Complied with the clinical trial protocol in the parent trial to the satisfaction of
the investigator.

- Able and willing to self-administer tralokinumab treatment (or have it administered by

adverse event (SAE) deemed related to tralokinumab by the investigator, which in the
opinion of the investigator could indicate that continued treatment with tralokinumab
may present an unreasonable safety risk for the subject.

- Subjects who, during their participation in the parent trial, developed an AE that was
deemed related to tralokinumab by the investigator and led to temporary
discontinuation of trial treatment, which in the opinion of the investigator could
indicate that continued treatment with tralokinumab may present an unreasonable safety
risk for the subject.

- Treatment with systemic immunosuppressive/immunomodulating drugs and/or systemic
corticosteroid within 4 weeks prior to baseline.
