Study to Investigate the Absorption, Metabolism, and Excretion of [14C]-AG-120

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02489513
Recruitment Status : Completed
First Posted : July 3, 2015
Last Update Posted : December 14, 2015

Brief Summary:
The study is designed to characterize the absorption, metabolism, and excretion of AG-120 using radiolabeled drug in healthy adult male subjects to support its further development and registration.

Condition or disease Intervention/treatment Phase
Healthy Volunteers Drug: [14C]-AG-120 Phase 1

Detailed Description:

This will be a single-center, open-label, study in healthy adult males. Each subject will participate in a screening phase, a baseline phase, a treatment phase, and a follow up period. Subjects who have met all inclusion criteria and none of the exclusion criteria at screening will return to the clinical site on Day -1 for baseline assessments. Following a 10 hour overnight fast, subjects will receive a single 500mg dose of AG-120 suspension containing a microtracer of [14C] AG-120 (~ 200 μCi) under fasted conditions. The study drug will be administered as an oral suspension with approximately 240 mL of room temperature, non-carbonated water.

Blood, urine, and fecal samples (and vomitus, if applicable) will be collected throughout the study for pharmacokinetic (PK), mass balance, and/or clinical laboratory assessments. Safety will be monitored throughout the study. Subjects will be discharged from the clinical site from Day 22 to Day 29, depending on the recovery of eliminated radioactivity.

Urine and fecal samples will be collected each day until Day 29 (or the point of discharge if earlier) for measurement of total [14C] radioactivity. Blood samples for radioanalysis and PK assessment, inclusive of metabolite profiling/characterization, will be collected at pre-dose and at specified intervals through Day 29. Total [14C]-radioactivity in whole blood, plasma, urine, and feces (and vomitus, if applicable ) will be determined.

Up to 8 subjects will enroll in the study. One to two additional subjects who have been confirmed as having poor metabolizer (PM) CYP2D6 genotype may be enrolled.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 55 Years   (Adult)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Is a healthy adult male of any race and aged 18 to 55 years, inclusive, at the time of signing the Informed Consent Form (ICF)
  2. Understands and voluntarily signs an ICF before any study-related assessments/procedures are conducted
  3. Is willing and able to adhere to the study visit schedule and other protocol requirements
  4. Is willing to provide a blood sample for genotyping of CYP2D6 status at Screening
  5. Is either sterile or agrees to use contraception from Check-in until 90 days following dose administration. The approved methods of contraception include: male condom with spermicide (foam, gel, film, cream, or suppository); sterile sexual partner (eg, tubal occlusion, hysterectomy, or bilateral salpingectomy); or by female sexual partner, established use of hormonal contraceptives, use of an intrauterine device with copper or intrauterine system with progestogen, barrier contraceptive (condom, diaphragm, or cervical/vault caps) used with spermicide, or true abstinence; periodic abstinence (eg, calendar, ovulation, symptothermal post-ovulation methods) is not an acceptable method of contraception.
  6. Must have a body mass index between 18 and 33 kg/m2, inclusive, at Screening
  7. Must be healthy as determined by the Investigator on the basis of medical history, physical examination, clinical laboratory test results, vital signs, and 12-lead ECG at Screening

    • Must be afebrile (febrile is defined as ≥38.5°C or 101.3°F)
    • Supine systolic blood pressure (BP) must be in the range of 90 to 140 mmHg, supine diastolic BP must be in the range of 50 to 90 mmHg, and pulse rate must be in the range of 40 to 110 beats per minute, as confirmed by repeat assessment if the initial vitals are out of range
    • Normal or clinically acceptable 12-lead ECG, with a QT interval corrected using Fridericia's formula (QTcF) value ≤430 msec
    • Calcium, magnesium, and potassium levels within normal ranges

Exclusion Criteria:

  1. History of any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study
