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.
This is a single group Phase 1/Phase 2, 1-arm, open-label study with SAR444836, an adeno-associated virus (AAV) vector-mediated gene transfer of human phenylalanine hydroxylase (PAH), for the treatment of adult participants with phenylketonuria (PKU) on a chronic, stable diet. The purpose of the study is to evaluate the safety and efficacy of SAR444836 in reducing phenylalanine (Phe) levels and in the elimination of a Phe restricted diet. Participants will receive a one-time intravenous (IV) administration of SAR444836. The study is constituted of 2 separate parts: a dose escalation part, and a dose expansion part where subsequent participants will be administered a safe and effective dose level identified during the dose escalation part. In both study parts, clinical and laboratory assessments will be collected to: a) assess the incidence of adverse events, and b) evaluate the effect of SAR444836 on reductions in blood Phe levels and maintenance of these Phe levels after elimination of a Phe restricted diet. The study duration will be for a minimum duration of 5 years following SAR444836 administration, for each participant and includes a 6-week screening phase, a 96-week treatment follow-up period after SAR444836 administration, followed by an additional 3 years of long-term safety (and efficacy) monitoring. There will be a total of 47 study visits. Many study visits may occur as remote visits and be performed by a qualified in-home service provider. Actual study duration for an individual participant may be longer than 5 years due to the administration of SAR444836 to participants in Stage 1A in a serial fashion, the duration of the screening period, and/or other factors such as delays in scheduling study visits.
A Phase 1/Phase 2, Open-label, Dose-escalation, and Dose Expansion Study to Evaluate the Safety, Tolerability, and Efficacy of SAR444836, an Adeno-associated Viral Vector-mediated Gene Transfer of Human Phenylalanine Hydroxylase, in Adult Participants With Phenylketonuria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
