14) Subject has any chronic infectious disease (eg, chronic urinary tract infection; chronic sinusitis; bronchiectasis; active pulmonary or systemic tuberculosis; chronic viral hepatitis, such as hepatitis C or hepatitis B [defined as positive for hepatitis B surface antigen]; or human immunodeficiency virus [HIV] infection).

19) Subject who has a history of alcohol or drug/chemical abuse based on the investigator’s clinical judgement.
20) Subject is judged by the investigator or the medical monitor to be inappropriate for the trial. |
1) Sujetos que no hayan completado su participación en los Ensayos 417-201-00007 o VIS649-201. 2) Sujetos con eventos adversos (EA) que limitarón el tratamiento durante los Ensayos 417-201-00007 o VIS649-201 y relacionados con IMP según el criterio del investigador que impediría la transferencia a este ensayo. 3) Incumplimiento, debido a que el sujeto no cumplió repetidamente con los procedimientos del ensayo durante el curso de su participación en los Ensayos 417-201-00007 y VIS649-201 (p. ej., sujetos que se consideró que no cumplieron con el programa de visitas, las evaluaciones del ensayo o el régimen de tratamiento). Se debe contactar al monitor médico si el investigador no está seguro de la elegibilidad de un sujeto. 4) Sujetos que tengan un resultado positivo en la prueba de embarazo antes de recibir IMP.
5) Varones heterosexuales biológicamente activos o sujetos en edad fértil, o sus parejas, que no acepten cumplir con los requisitos anticonceptivos desde el momento del consentimiento hasta el final de la participación del sujeto en el ensayo y 90 días adicionales (sujetos biológicos masculinos) o 30 días (sujetos biológicos femeninos) a partir de entonces.
