NCT07461493
The goal of this observational study is to establish a patient registry and a biorepository (sample collection and storage) to investigate health disparities, access, and barriers to cancer screening and early detection technologies. The registry and biorepository will serve as a resource to support Cancer Early Detection (CED) screenings and future research focused on communities at increased risk for cancer. The study seeks to address: •Barriers and disparities in cancer prevention, screening, and treatment, particularly in historically underrepresented populations. Participants will: * Attend a minimum of five clinic visits over a five-year period for scheduled annual assessments while actively enrolled in the study. * Complete questionnaires at each visit that collect information on their medical history, cancer history, and family cancer history. * Allow relevant health information from their electronic health records (EHR) to be collected and reviewed. * Provide blood, saliva, and stool samples for research purposes. * Enter a long-term follow-up period for an additional five years.
NCT06971731
The goal of this Phase 3, randomized study is to assess the safety, efficacy, tolerability, and pharmacokinetics (PK) of oral JNT-517 in adults (18 years of age or older) with PKU. Participants will receive either JNT-517 or placebo and will be blinded to their treatment assignment. Participants will have a 2 in 3 (or approximately 67%) chance of receiving JNT-517 during the first part of the study which will last approximately six weeks. During the second part of the study every participant who continues in the study will receive one of two doses of JNT-517 for an additional 46 weeks. The study requires a screening period of up to 35 days to ensure dietary stabilization and amino acid levels required to meet study eligibility. In total, participation in the study could last for up to 400 days. Participants will: Take 75 mg JNT-517 or 150 mg JNT-517, or a placebo BID (2x per day) for approximately 365 days; Visit the clinic or have a mobile health nurse visit your home for checkups and tests; Collect urine sample at home and bring to clinic on specified days; Keep a food diary 3 days before each study visit
