E.3 | Principal inclusion criteria |
1. Subjects with PNH who have participated in an APL-2 clinical trial. Subjects who received treatment with APL-2 must have experienced clinical benefit in the opinion of the Investigator. Note: Subjects with PNH who completed an APL-2 clinical trial without receiving APL-2 (or without receiving APL-2 for long enough to demonstrate clinical benefit) may be enrolled in this study if, in the opinion of the Investigator, the subject is expected to demonstrate clinical benefit upon the initiation or continuation of APL-2 therapy. 2. Willing and able to give written informed consent. 3. Women of child-bearing potential (WOCBP) must have a negative pregnancy test and must agree to continue to use an approved method of contraception for the duration of the study and 60 days after their last dose of study drug. 4. Males must agree to continue to use an approved method of contraception and must agree to refrain from donating sperm for the duration of the study and 60 days after their last dose of study drug. |
1. Pacientes con HPN que participaron en un ensayo clínico de APL-2. Los pacientes que recibieron tratamiento con APL-2 deben haber obtenido beneficios clínicos según el Investigador. Nota: Los pacientes con HPN que completaron un ensayo clínico de APL-2 sin recibir APL-2 (o sin haber recibido APL-2 por tiempo suficiente para demostrar beneficios clínicos) pueden participar en este estudio si, según el Investigador, se espera que el paciente demuestre beneficios clínicos al iniciar o continuar el tratamiento con APL-2. 2. Los pacientes que deseen y puedan brindar su consentimiento informado por escrito. 3. Las mujeres en edad fértil (women of child-bearing potential, WOCBP) deben tener una prueba de embarazo negativa y deben aceptar continuar con el uso de un método anticonceptivo aprobado durante la vigencia del estudio y 60 días después de su última dosis del medicamento en estudio. 4. Los hombres deben aceptar continuar con el uso de un método anticonceptivo aprobado y abstenerse de donar esperma durante la vigencia del estudio y 60 días después de su última dosis del medicamento en estudio. |

E.4 | Principal exclusion criteria |
1. Subjects who have withdrawn from an APL-2 clinical study 2. Any condition that could increase the subject’s risk by participating in the study |
1. Los pacientes que se hayan retirado de un estudio clínico de APL-2. 2. Toda enfermedad que podría aumentar el riesgo del paciente al participar en el estudio |
