E.3 | Principal inclusion criteria |
1. Willing and able to understand and provide written informed consent prior to any study-related procedures and to comply with all study requirements and complete study assessments. 2. Must have qualified for and received IP (daxdilimab or placebo) and complete the treatment period (through Day 337) in the RECAST SLE study. Subjects who discontinued early from IP in RECAST SLE are not eligible for this study. 3. Women of childbearing potential must have a negative urine pregnancy test on Day 1. Women of childbearing potential are defined as those who are not surgically sterile (ie, surgical sterilization includes bilateral salpingectomy, bilateral oophorectomy, or hysterectomy) or those who are not postmenopausal (defined as 12 months with no menses without an alternative medical cause and a follicle-stimulating hormone [FSH] within the postmenopausal range as established by the central laboratory during the screening period of the RECAST SLE study, unless on postmenopausal hormone replacement therapy).If a female subject becomes postmenopausal during the study (ie, 12months with no menses without an alternative medical cause, unless on postmenopausal hormone replacement therapy), a FSH test will be performed at the central laboratory. If the FSH level is within the postmenopausal range, the female subject will not be required to use contraception after that. Women of childbearing potential who are sexually active with a nonsterilized male partner must agree to use a highly effective method of contraception from signing of the ICF and must agree to continue using such precautions through the end of the study follow-up or 3months (approximately 5 half-lives) following the last dose of IP in the case of early withdrawal from the study, and refrain from egg retrieval/egg donation during this period. After this point, a decision about contraception should be made by the subject and her regular healthcare providers. Female subjects who participate in the SLE OLE are expected to maintain the same form of contraception they used during the RECAST SLE study. Sustained abstinence is an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Note that because mycophenolate affects the metabolism of hormonal contraceptives and may reduce their effectiveness in women receiving MMF or mycophenolic acid (MPA) who are using hormonal contraceptives for birth control, the subject must employ an additional contraceptive method (eg, barrier method). 4. Nonsterilized male subjects who are sexually active with a woman partner of childbearing potential must agree to use a condom with spermicide from Day 1 and until 3 months (approximately 5 half-lives) after receipt of the last dose. Because a male condom with spermicide is not a highly effective contraception method, it is strongly recommended that male subjects advise their women partners of childbearing potential to use a highly effective method of contraception throughout this period. |
1. Disposición y capacidad para comprender y otorgar el consentimiento informado por escrito antes de realizar ningún procedimiento relacionado con el estudio y para cumplir todos los requisitos del estudio y completar las evaluaciones del estudio. 2. Deben haber cumplido los requisitos y haber recibido el PEI (daxdilimab o placebo) y completar el período de tratamiento (hasta el día 337) en el estudio RECAST SLE. Los sujetos que hayan abandonado prematuramente el PEI en el estudio RECAST SLE no podrán participar en este estudio. 3. Las mujeres en edad fértil deben tener una prueba de embarazo negativa en orina el día 1. Las mujeres en edad fértil se definen como las que no están esterilizadas quirúrgicamente (la esterilización quirúrgica comprende salpingectomía bilateral, ovariectomía bilateral o histerectomía) o las que no son posmenopáusicas (definido como 12 meses sin menstruación sin una causa médica alternativa y una concentración de folitropina [FSH] dentro del intervalo posmenopáusico establecido por el laboratorio central durante el período de selección del estudio RECAST SLE, salvo en caso de tratamiento hormonal sustitutivo posmenopáusico). Si una mujer pasa a ser posmenopáusica durante el estudio (es decir, 12 meses sin menstruación sin una causa médica alternativa, a menos que reciba tratamiento hormonal sustitutivo posmenopáusico), se realizará un análisis de FSH en el laboratorio central. Si la concentración de FSH está dentro del intervalo posmenopáusico, no será necesario que la mujer utilice métodos anticonceptivos a partir de ese momento. Las mujeres en edad fértil que mantengan relaciones sexuales con una pareja masculina no esterilizada deberán comprometerse a utilizar un método anticonceptivo muy eficaz desde la firma del DCI y a seguir adoptando tales precauciones hasta el final del seguimiento del estudio o hasta 3 meses (aproximadamente 5 semividas) después de la última dosis del PEI en caso de retirada prematura del estudio y abstenerse de la extracción/donación de óvulos durante este periodo. Después de este momento, la paciente y sus profesionales sanitarios habituales tomarán una decisión sobre el uso de anticonceptivos. Se espera que las mujeres que participen en la EA del estudio del LES continúen con el mismo método anticonceptivo que usaron durante el estudio RECAST SLE. La abstinencia mantenida es una práctica aceptable; sin embargo, la abstinencia periódica, el método de Ogino y el coito interrumpido no son métodos anticonceptivos aceptables. Hay que señalar que, dado que el micofenolato afecta al metabolismo de los anticonceptivos hormonales y podría reducir su eficacia en las mujeres tratadas con MMF o ácido micofenólico (AMF) que utilicen anticonceptivos hormonales, la paciente deberá utilizar un método anticonceptivo adicional (por ejemplo, un método de barrera). 4. Los pacientes varones no esterilizados que mantengan relaciones sexuales con una pareja femenina en edad fértil deberán comprometerse a utilizar preservativo con espermicida desde el día 1 hasta 3 meses (aproximadamente 5 semividas) después de recibir la última dosis. Dado que el preservativo masculino con espermicida no es un método anticonceptivo muy eficaz, se recomienda que los pacientes varones indiquen a sus parejas mujeres en edad fértil que utilicen un método anticonceptivo muy eficaz durante todo este período. |

E.4 | Principal exclusion criteria |
1. Any condition or change during the RECAST SLE study that in the opinion of the Investigator or the Sponsor would interfere with evaluation and interpretation of subject safety or alter the risk-benefit associated with IP administration. 2. Participation in another clinical study with an IP during the RECAST SLE study period. 3. Planned elective surgeries that in the opinion of the Investigator or the Sponsor would interfere with evaluation and interpretation of subject safety. 4. Any herpes zoster, cytomegalovirus, or Epstein-Barr virus infection that was not completely resolved prior to Visit 1. 5.
