Un estudio para evaluar eventos adversos y cómo se mueve por el cuerpo el pivekimab sunirine intravenoso (IV) en participantes pediátricos con leucemia mieloide aguda (LMA) recidivante o refractaria

1 de octubre de 2026 actualizado por: AbbVie

Estudio de Fase 1b de la Seguridad y Farmacocinética de Pivekimab Sunirine en Pacientes Pediátricos con Leucemia Mieloide Aguda (LMA) Recidivante o Refractaria

Acute myeloid leukemia (AML) is an aggressive blood cancer, withwith few options for participants who relapse after treatment or who don't respond to treatment. This study will assess the adverse events and how pivekimab sunirine moves through the body in pediatric participants with relapsed or refractory (R/R) AML.

Pivekimab sunirine is a drug being evaluated in the treatment of AML. This is an open label, single arm study, participants will be enrolled in 1 of the 3 cohorts based on their age and will receive pivekimab sunirine at a dose based on their weight. Around 18 pediatric participants with a diagnosis of AML will be enrolled in the study at approximately 30 sites around the world.

Participants will receive intravenous (IV) pivekimab sunirine alone. The total study duration is approximately 28 months.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, and checking for side effects.
