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

In this study, researchers will learn more about BIIB141, also known as omaveloxolone or SKYCLARYS®. This drug has been approved, or made available for doctors to prescribe, for people with Friedrich's Ataxia (FA) who are at least 16 years old. This is called a "drug-drug interaction" study. In this kind of study, researchers are looking at what happens when 2 or more medicines affect each other in the body. This could change how 1 or both of the drugs work, either making them stronger, weaker, or causing health problems. The main goal of this study is to learn if taking BIIB141 affects how omeprazole is processed in the body. Omeprazole is a commonly used medicine to help lower the amount of acid the stomach makes. The main question researchers want to answer in this study is : • How does the body process omeprazole when taken with BIIB141? Researchers will also learn more about : * How many participants have adverse events during the study. An adverse event is a health problem that may or may not be caused by the study drug. * How many participants have adverse reactions during the study. An adverse reaction is a health problem that may be caused by the study drug. * If there are any changes in the participants' overall health during the study. This study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 28 days, after which participants will check into their study research center. * Participants will stay at the study research center for about 17 days. * This is an "open label" study. In this kind of study, the participants, study doctor, and site staff know which study drug the participant is taking. In this study, all participants took BIIB141 and omprezole. * Participants will take omeprazole on Day 1 and Day 16. They will also take BIIB141 once a day from Day 2 through Day 16. * Throughout the study, researchers will take participants' blood and urine samples. Researchers will also do other tests to check the participants' overall health and will ask participants how they are feeling. * Each participant will be in the study for up to 45 days.

Inclusion Criteria	Exclusion Criteria
* All female participants of childbearing potential must have negative results for pregnancy tests as follows: 1. At screening, based on a serum sample obtained within 28 days prior to initial study drug administration; and 2. Prior to dosing, based on a serum sample obtained on Study Day -1. * Body mass index (BMI) at screening between 18 and 32 kilograms per square meter (kg/m\^2), inclusive.	* History of any clinically significant cardiac, endocrine, gastrointestinal, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, or renal disease, or other major disease, as determined by the Investigator. * Clinically significant, as determined by the Investigator, 12-lead electrocardiogram (ECG) abnormalities. * History of, or positive test result at Screening for, human immunodeficiency virus (HIV). * History of hepatitis C infection or positive test result at Screening for hepatitis C virus antibody (HCV Ab). * Current hepatitis B infection \[defined as positive for hepatitis B surface antigen (HBsAg) and/or total anti-HBc\]. Participants with immunity to hepatitis B from previous natural infection (defined as negative HBsAg, positive anti-HBc, and positive anti-HBs) or vaccination (defined as negative HBsAg, negative anti-HBc, and positive anti-HBs) are eligible to participate in the study. * Chronic, recurrent, or serious infection (e.g., pneumonia, septicemia, and herpes simplex virus), as determined by the Investigator, within 90 days prior to Screening or between Screening and Day -1. * Symptoms of bacterial, fungal, or viral infection (including upper respiratory tract infection) within 14 days prior to Screening or between Screening and Day -1. Participants with local fungal infection (e.g., candidiasis, tinea) are eligible to be rescreened after successful treatment of the infection. * Prior exposure to omaveloxolone.
