Study to Evaluate the Effect of Multiple Doses of Itraconazole and Rifampin on the Single-Dose Pharmacokinetics of Mitapivat Sulfate (AG-348) in Healthy Adult Participants

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

Part 1 of this study will determine the effect of multiple-dose itraconazole, a strong cytochrome P450 (CYP) 3A4 and P-glycoprotein (P-gp) inhibitor, on the single-dose pharmacokinetic(s) (PK) of mitapivat sulfate in healthy adult participants. Part 2 of this study will determine the effect of multiple-dose rifampin, a strong CYP3A4 and P-gp inducer, on the single-dose pharmacokinetic(s) (PK) of mitapivat sulfate in healthy adult participants.

Who can join

Age: 18 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Healthy, adult, male or female (non-childbearing potential), 18-55 years of age, inclusive, at the time of providing written informed consent;
• Continuous non-smoker who has not used nicotine-containing products for at least 12 months prior to screening, based on participant self-reporting, and agrees to abstain from use throughout the study;
• Body mass index (BMI) ≥ 18.0 and ≤ 32.0 kilograms per meter squared (kg/m2) at screening;
• Medically healthy, with no clinically significant conditions or abnormalities, as determined by the principal investigator (PI) or designee, through evaluation of medical history and screening vital signs, 12-lead electrocardiogram (ECG) results, physical examination findings, and clinical laboratory test results;
• A female participant must be of non-childbearing potential and must have undergone one of the following sterilization procedures at least 6 months prior to the first dosing:
• hysteroscopic sterilization;
• bilateral tubal ligation or bilateral salpingectomy;
• hysterectomy;
• bilateral oophorectomy.
• or be postmenopausal with amenorrhea for at least 1 year prior to the first dosing and follicle-stimulating hormone (FSH) serum levels at screening consistent with postmenopausal status;
• A male participant (with or without prior vasectomy) must agree to use a condom with spermicide or abstain from sexual intercourse from the time of providing written informed consent until 90 days after the last dose of study drug;
• If male, must agree not to donate sperm from the first dosing until 90 days after the last dose of study drug;
• Understands the study procedures in the informed consent form (ICF), and is willing and able to comply with the study procedures and the protocol requirements, and has provided signed written informed consent prior to performing any study procedures, including screening procedures;

You may not qualify if…

• Is mentally or legally incapacitated or has significant emotional problems at the time of the screening visit or expected during the conduct of the study;
• History or presence of any clinically significant medical or psychiatric condition or disease or clinically significant laboratory abnormality that, in the opinion of the PI or designee, might confound the results of the study, compromise the ability of the participant to complete study procedures, and/or pose an additional risk to the participant by their participation in the study. This includes seizure disorders, transient ischemic attacks, or easy bruising;
• History or presence of a medical condition or surgical procedure that, in the opinion of the PI or designee, may potentially interfere with absorption, distribution, metabolism, or excretion of the study drugs;
• History or presence of alcohol or drug abuse within the past 2 years prior to screening;
• History or presence of hypersensitivity, idiosyncratic reaction, or serious adverse reaction to any of the study drugs or to their formulation excipients;
• Female participants of childbearing potential;
• Female participants with a positive serum pregnancy test at screening or check-in or who are breastfeeding;
• Positive urine drug or alcohol results at screening or check-in;
• Positive results at screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody;
• Supine blood pressure is less than 90/40 milliliters of mercury (mmHg) or greater than 140/90 mmHg at screening. If the participant's systolic blood pressure reading exceeds 140 mmHg or the diastolic blood pressure reading exceeds 90 mmHg due to what may be, in the opinion of the PI or designee, an episode of transient anxiety, the reading may be repeated, and the resulting blood pressure measurement used to determine eligibility;
• Supine heart rate is lower than 40 beats per minute (bpm) or higher than 99 bpm at screening. If the participant's heart rate exceeds 99 bpm due to what may be, in the opinion of the PI or designee, an episode of transient anxiety, the reading may be repeated, and the resulting heart rate measurement used to determine eligibility;
• QTcF interval is >450 milliseconds (msec) (males) or >470 msec (females) or has ECG findings deemed abnormal with clinical significance by the PI or designee at screening;
• Estimated creatinine clearance < 90 mL/min at screening (Cockcroft-Gault formula);
• Unable to refrain from or anticipates the use of any drug, including prescription and non-prescription medications, proton pump inhibitors, H2-antagonists, herbal remedies, and vitamin supplements, beginning 28 days prior to the first dosing and throughout the study. Additionally, any drugs (with the exception of the study drugs) known to be clinically significant inhibitors or inducers of CYP3A, CYP2C9, CYP2C8, CYP2C19, and CYP1A2 enzymes and/or P-gp, including St. John's Wort, beginning 28 days prior to the first dosing and throughout the study. Appropriate sources (e.g., Flockhart TableTM) will be consulted to confirm lack of PK/PD interaction with study drugs. After first dosing, acetaminophen (up to 2 g per 24 hours) may be administered at the discretion of the PI or designee;
• Has consumed foods or beverages containing caffeine or xanthines 24 hours prior to the first dosing and is not willing to refrain from consumption of these foods or beverages throughout the study;
• Has consumed alcohol 48 hours prior to the first dosing and is not willing to refrain from consumption of alcohol throughout the study;
• Has consumed foods or beverages containing grapefruit or Seville oranges for 14 days prior to the first dosing and is not willing to refrain from consumption of these foods or beverages throughout the study;
• Has consumed fruit juices 72 hours prior to the first dosing and is not willing to refrain from consumption of these juices throughout the study
• Has consumed vegetables from the mustard green family (e.g., kale, broccoli, watercress, collard greens, kohlrabi, Brussel sprouts, and mustard), and charbroiled meats for 7 days prior to first dosing and is not willing to refrain from consumption of these foods throughout the study;
• Has been on a diet incompatible with the on-study diet, in the opinion of the PI or designee, within the 30 days prior to the first dosing;
• Donation of blood or significant blood loss (≥500 mL) within 3 months prior to the first dosing and must be willing to refrain from voluntary blood donation for at least 30 days after the last dose of study drug;
• Plasma donation within 7 days prior to screening;
• Has liver function tests including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and total bilirubin that are greater than the upper limit of normal at screening or check-in (confirmation of results may be done once);
• Has platelet, hemoglobin, and hematocrit that are below the lower limit of normal at screening or check-in (confirmation of results may be done once).
• History or presence of liver disease;
