Study summary

This research study is examining multiple doses of voxelotor (a study drug intended for treatment of sickle cell disease) and how it interacts with additional substrates (substrates are drugs or other substances that are metabolized by cytochrome enzymes. The substrates used in this study are FDA approved medications). The study will help to determine the safety and tolerability of the study drugs taken together, as well as the pharmacokinetics (PK) on how your body processes and responds to the combination of the study drug and substrates. Although these drugs are FDA approved, their use in this study is experimental.

Read the detailed description

This is an open-label, fixed-sequence, 2-period evaluation study. This means the study doctor and participants in the study will know what study drugs they are taking. There will be approximately 46 healthy male and female participants between the ages of 18 - 55. There will be two parts of the study: parts A and B.

Part A will consist of 26 healthy male and female participants (at least 20% African American). For Part A, participant involvement is expected to last approximately 81 days, including a 33-day screening period and a 48-day on study period (consisting of 2 study treatment periods, a washout period lasting 7 to 14 days, and the Follow-up visit).

Part B will consist of 20 healthy male and female participants (at least 20% African American). For Part B, participant involvement is expected to last approximately 68 days, including a 33-day screening period and a 35-day on study period (consisting of 2 study treatment periods, a washout period lasting 7 to 14 days, and the Follow-up visit).

You will only be allowed to be in one part of the study.

Inclusion criteria

    1. Males or females ≥ 18 and ≤ 55 years of age inclusive, at the time of signing the informed consent.

      1. No clinically significant findings as assessed by review of medical and surgical history, vital signs assessments, 12-lead electrocardiograms (ECG), physical examination, and clinical laboratory evaluations conducted at screening and day of admission. A single repeat measurement/test may be performed to confirm eligibility based upon initial vital signs, ECG, or clinical laboratory tests abnormalities.
      1. Body mass Index (BMI) ≥ 18.0 and ≤ 30.0 kg/m2, and body weight ≥ 50 kg at screening and Period 1 Day -1. BMI = weight (kg)/(height [m])2
      1. Females of childbearing potential must agree to use a highly effective method of contraception or practice abstinence from 2 weeks prior to study start through 30 days after the last dose of study drug. A highly effective method of contraception is defined as one that results in a low documented failure rate when used consistently and correctly such as: condom plus use of an intrauterine device; intrauterine system or hormonal method of contraception (oral, injected, implanted, or transdermal) for their female partner; or sexual abstinence. Males must be surgically sterilized, or agree to practice true abstinence, or use acceptable contraception if sexually active with a female partner of childbearing potential, throughout the study, and for at least 30 days after the last dose of study drug.

Other outcomes

  1. Part A: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    An adverse event (AE) was defined as any untoward medical occurrence in a participant administered a pharmaceutical product during the course of a clinical investigation.

TEAE: any event that was not present before exposure to study drug (voxelotor or cocktail drugs \[probe substrates\]) or any event already present that worsened in either intensity or frequency after exposure to study drug. An SAE was defined as an AE that at any dose resulted in any of the following outcomes: death; life-threatening AE; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant incapacity or disability; a congenital anomaly/birth defect; other important medical events.

Other pre-specifiedPart A: Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

An adverse event (AE) was defined as any untoward medical occurrence in a participant administered a pharmaceutical product during the course of a clinical investigation. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product, whether or not thought to be related to the investigational product. TEAE: any event that was not present before exposure to study drug (voxelotor or cocktail drugs \[probe substrates\]) or any event already present that worsened in either intensity or frequency after exposure to study drug. An SAE was defined as an AE that at any dose resulted in any of the following outcomes: death; life-threatening AE; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant incapacity or disability; a congenital anomaly/birth defect; other important medical events.

Other pre-specifiedPart A: Number of Participants With Clinically Significant Abnormalities in Laboratory Tests

The following laboratory parameters were assessed: hematology: hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, platelet count, red blood cell count, neutrophils, monocytes, lymphocytes, basophils and eosinophils. coagulation: prothrombin time, partial thromboplastin time, international normalized ratio. Serum Chemistry: albumin, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, creatinine, blood urea nitrogen, lactate dehydrogenase. Urinalysis: ketones, pH, protein, blood glucose, bilirubin, chloride, bicarbonate, phosphorous, potassium was assessed. Clinical significance of laboratory abnormalities was determined by investigator.

Vital signs included oral temperature, heart rate, respiratory rate (breaths per minute), and blood pressure. Blood pressure and heart rate were measured in a supine position using completely automated device after at least 5 minutes of rest for the participant in a quiet setting without distractions. Clinical significance of vital signs was determined by investigator.
