• Patients who completed treatment in the parent trials (1305-0014, 1305-0023, or 1305-0035) without prematurely discontinuing treatment permanently according to protocol (i.e. completed treatment with or without temporary treatment interruption)

• Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial

• Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. WOCBP taking oral contraceptives (OCs) also have to ensure the use of one barrier method during sexual intercourse with their partner, e.g., condom to account for the risk of potentially reduced efficacy of the OCs in the event of severe vomiting and diarrhoea. For France, fertile males must be ready and able to use acceptable methods of birth control
