Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a dose escalation study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of SIF001, a monoclonal antibody with the potential to treat epilespy

Known history of hypersensitivity or anaphylactic reaction to intravenous medications, biologicals, or fluids. 15. History of any clinically significant disease or disorder which, in the opinion of the investigators, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study. 16. History of status epilepticus within 2 years of screening 17. Known history of suicidality within 2 years of screening, or answering "yes" to questions 4 and 5 of the Columbia Suicide Severity Rating Scale (C-SSRS) 18.
