Influence of Fedratinib on the Pharmacokinetics of the Transporter Probe Substrates Digoxin, Rosuvastatin, and Metformin

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

This is a nonrandomized, fixed-sequence, open-label study to evaluate the effect of a single dose of fedratinib on the PK, safety, and tolerability of single doses of digoxin, rosuvastatin, and metformin in healthy subjects. The subjects will participate as follows: * Screening phase * Treatment phase (includes baseline) * Follow-up telephone call Subjects will be screened for eligibility during the screening phase. Subjects who meet all inclusion criteria and none of the exclusion criteria will return to the clinical site on Day -1 for protocol-specified assessments, and will be domiciled at the clinical site from Day -1 through the morning of Day 22. During the study, blood samples will be collected at prespecified times for PK and PD. Urine samples will be collected at prespecified times for urinary PK evaluation of metformin. Subject safety will be monitored throughout the study.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Subjects must satisfy the following criteria to be enrolled in the study:
• Subject must understand and voluntarily sign an informed consent form (ICF) prior to any study-related assessments/procedures being conducted.
• Subject must be willing and able to communicate with the Investigator and adhere to the study visit schedule and other protocol requirements.
• Subject is male or female of any race ≥ 18 to ≤ 65 years of age at the time of signing the ICF.
• Female subjects NOT of childbearing potential must:
• a. Have been surgically sterilized (hysterectomy or bilateral oophorectomy; proper documentation required) at least 6 months before Screening, or postmenopausal (defined as 24 consecutive months without menses before Screening, with a follicle-stimulating hormone [FSH] level in the post-menopausal range according to the laboratory used at Screening).
• Females of childbearing potential (FCBP1) must:
• Have a negative pregnancy test as verified by the investigator at Screening and Baseline (prior to starting study treatment). She must agree to ongoing pregnancy testing during the course of the study, as applicable, and after end of study treatment. This applies even if the subject practices true abstinence from heterosexual contact.
• Either commit to true abstinence from heterosexual contact (which must be reviewed on a monthly basis, as applicable, and source documented) or agree to use, and be able to comply with, any one of the following highly effective contraception methods without interruption, beginning at least 14 days prior to starting investigational product (IP), during the study treatment, and for at least 30 days after the last dose of IP. - Intrauterine device (IUD; non-hormonal only); tubal ligation; or a partner with a vasectomy. The chosen form of birth control must be effective by the time the subject receives the first dose of IP.
• Male subjects must:
• a. Practice true abstinence from heterosexual contact (which must be reviewed on a monthly basis, as applicable, and source documented) or agree to use a barrier method of birth control (condoms not made from natural [animal] membrane [latex condoms are recommended]) during sexual contact with a pregnant female or FCBP while receiving study treatment, and for at least 30 days after the last dose of IP, even if he has undergone a successful vasectomy.
• Must have a body mass index (BMI) ≥ 18 and ≤ 33 kg/m2 at screening.
• Must be healthy, as determined by the Investigator on the basis of medical history, physical examination (PE), clinical laboratory test results, vital signs, and 12-lead electrocardiogram (ECG) at screening and check-in (Day -1), as applicable:
• Aspartate aminotransferase (AST), ALT, and total bilirubin must be at or below the upper limit of the reference range on or before check-in (Day -1). Other clinical laboratory results must be either within normal range or deemed not clinically significant by the Investigator. Any out of range lab tests may be repeated up to 1 time during Screening and up to 1 time at check-in per Investigator discretion to confirm eligibility.
• Must be afebrile (febrile is defined as ≥ 38°C or 100.3°F).
• Supine systolic blood pressure (BP) must be in the range of 90 to 140 mmHg (inclusive), supine diastolic BP must be in the range of 50 to 90 mmHg (inclusive), and pulse rate must be in the range of 45 to 100 bpm (inclusive) at screening.
• Subject has a normal or clinically acceptable 12-lead ECG at screening; male subjects must have a corrected QT interval using Fridericia's formula (QTcF) value ≤ 430 msec and females must have a QTcF value ≤ 450 msec. An ECG may be repeated up to 2 times, and the average of the QTcF values will be used to determine subject eligibility.

You may not qualify if…

• The presence of any of the following will exclude a subject from enrollment:
• History (within 3 years prior to Screening) of any clinically significant neurological, GI, hepatic, renal, respiratory, cardiovascular, metabolic, endocrine, hematological, dermatological, psychological, or other major disorders as determined by the Investigator.
• Any condition, including the presence of laboratory abnormalities, that places the subject at unacceptable risk if he or she were to participate in the study or confounds the ability to interpret data from the study (congenital nonhemolytic hyperbilirubinemia [eg, Gilbert's syndrome] is not acceptable).
• Subject has prior history of Wernicke's Encephalopathy (WE).
• Subject has signs or symptoms of WE (eg, ataxia, ocular paralysis, or cerebellar signs) without documented exclusion of WE by thiamine level and brain magnetic resonance imaging (MRI).
• Subject has thiamine deficiency, defined as thiamine levels in whole blood below normal range according to institutional standard.
• Subject has an estimated glomerular filtration rate (GFR) of <90 mL/min/1.73 m2 based on the 4-variable Modification of Diet in Renal Disease (MDRD) equation.
• Use of any prescribed systemic or topical medication, including vaccines, within 30 days of the first dose administration (with the exception of any palonosetron administered for purposes of this study).
• Use of any nonprescribed systemic or topical medication (including vitamin/mineral supplements and herbal medicines) within 14 days of the first dose administration (with the exception of acetaminophen up to 2 grams/day for no more than 3 consecutive days to treat minor illness or headache [per Investigator judgment]).
• Use of any metabolic enzyme or relevant transporter inhibitors or inducers that would affect the relevant drugs within 30 days of the first dose administration unless determined by the Investigator that there will be no impact on the study integrity or subject safety.
• The Indiana University "P450 Drug Interaction Table" should be used to determine inhibitors and/or inducers of metabolic enzymes (http://medicine.iupui.edu/clinpharm/ddis/table/aspx). The Sponsor should be contacted for questions about potential drug-drug interactions and exclusions/prohibitions when necessary.
• Exposure to an investigational drug (new chemical entity) within 30 days preceding the first dose administration or 5 half-lives of that investigational drug, if known (whichever is longer).
• Presence of any surgical or medical conditions possibly affecting drug absorption, distribution, metabolism, and excretion (eg, bariatric procedure, cholecystectomy).

• History of alcohol abuse (as defined by the current version of the DSM) within 2 years before dosing or positive alcohol screen.
• Known to have serum hepatitis; known to be a carrier of the hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), or hepatitis C antibody (HCV Ab); have a positive result to the test for hepatitis B or hepatitis C virus at screening or have a positive result to the test for human immunodeficiency virus (HIV) antibodies at screening. Subjects whose results are compatible with prior immunization (including natural and vaccination) against hepatitis B may be included at the discretion of the Investigator.
