E.3 | Principal inclusion criteria |
1. Able to provide written informed consent. 2. Non-pregnant, non-lactating female subjects. 3. Subjects with PNH who have completed treatment in another BCX9930 clinical study and, in the opinion of the investigator, would benefit from continued treatment with BCX9930. 4. Female participants will continue to meet at least one of the following requirements per the prior study: a. Be a woman of nonchildbearing potential. b. Be a woman of childbearing potential who agrees to use a highly effective contraceptive method throughout the study and for a duration of 30 days after the last dose of BCX9930. c. Alternatively, true abstinence is acceptable for women of childbearing potential when it is in line with the subject’s preferred and usual lifestyle. 5. Male participants will continue to meet at least one of the following requirements per the prior study: a. Males with a female partner of childbearing potential (including a pregnant partner) must use condoms throughout the study and for a duration of 90 days after the dose of BCX9930 unless their partner is using a highly effective contraceptive method independent of the study. b. Alternatively, true abstinence is acceptable when it is in line with the subject’s preferred and usual lifestyle. 6. In the opinion of the investigator, the subject is expected to adequately comply with all required study procedures and restrictions for the study |
1. Ser capaz de proporcionar un consentimiento informado por escrito. 2. Mujeres no embarazadas ni lactantes. 3. Los sujetos con HPN que hayan completado el tratamiento en otro estudio clínico BCX9930 y, en opinión del investigador, se beneficiarían de un tratamiento continuo con BCX9930. 4. Las participantes de sexo femenino continuarán cumpliendo al menos uno de los siguientes requisitos según el estudio anterior: a. Ser una mujer no fértil. b. Ser una mujer en edad fértil que acepte utilizar un método anticonceptivo altamente efectivo durante todo el estudio y durante 30 días después de la última dosis de BCX9930. c. Como alternativa, la verdadera abstinencia es aceptable para las mujeres en edad fértil, siempre que esto pueda llevarse a cabo, teniendo en cuenta el estilo de vida preferido y habitual de la paciente. 5. Los participantes de sexo masculino continuarán cumpliendo al menos uno de los siguientes requisitos según el estudio anterior: a. Los hombres con una pareja femenina en edad fértil (incluida una pareja embarazada) deben usar preservativos durante todo el estudio y por un período de 90 días después de la dosis de BCX9930, a menos que su pareja esté utilizando un método anticonceptivo altamente eficaz independiente del estudio. b. Como alternativa, la verdadera abstinencia es aceptable, siempre que esto pueda llevarse a cabo, teniendo en cuenta el estilo de vida preferido y habitual del paciente. 6. En opinión del investigador, se espera que el sujeto cumpla adecuadamente con todos los procedimientos y restricciones de estudio requeridos para el estudio. |

E.4 | Principal exclusion criteria |
1. Any clinically significant medical or psychiatric condition including alcohol or drug dependency that, in the opinion of the investigator or sponsor, would interfere with the subject’s ability to participate in the study or increase the risk of participation for that subject. 2. An ongoing adverse event (AE), including a laboratory abnormality, or other unacceptable toxicity that, in the judgment of the investigator, compromises the ability of the subject to continue study-specific procedures or it is considered not to be in the subject’s best interest to continue or benefit-risk assessment is no longer in favor of the subject’s continued treatment. 3. Daily use of medications listed in the currently applicable prohibited medications list. 4. Known or suspected hypersensitivity to BCX9930 or any of its formulation excipients (Note: prior drug rash is not exclusionary). |
1. Cualquier afección médica o psiquiátrica clínicamente significativa, incluyendo dependencia al alcohol o las drogas, que en opinión del investigador o promotor pueda interferir con la capacidad del sujeto para participar en el ensayo, o aumentar el riesgo de participación para este sujeto. 2. Un acontecimiento adverso (AA) continuo, que incluye una anormalidad de laboratorio u otra toxicidad inaceptable que, a juicio del investigador, compromete la capacidad del sujeto para continuar los procedimientos específicos del estudio o se considera que no es lo mejor para el sujeto continuar o la evaluación de riesgo-beneficio ya no está a favor del tratamiento continuo del sujeto. 3. Uso diario de fármacos actualmente incluidos en la lista de medicamentos prohibidos en vigor en ese momento. 4. Hipersensibilidad conocida o sospechada a BCX9930 o cualquiera de sus excipientes de formulación (Nota: la erupción previa del fármaco no es excluyente). |
