Brief Summary:
This will be a double-blind, randomized, placebo-controlled, single ascending dose, Phase I study in healthy male subjects.

Condition or disease Intervention/treatment Phase
IBD Drug: AKB-4924 Other: Placebo Phase 1

Detailed Description:
Single oral doses of AKB-4924 will be investigated in up to 6 sequential cohorts of 8 healthy male subjects. Primarily 6 dose levels are planned; the proposed doses are 20 mg, 60 mg, 120 mg, 240 mg, 360 mg, and 480 mg. Actual doses may be decreased or increased based on the safety and tolerability of the drug, as determined by the Investigator and Sponsor. Additional cohorts may be added as needed to test lower, higher, or repeat doses.

Exclusion Criteria:

  1. Non-vasectomized male subjects and their female partners who are unable or unwilling to use an acceptable method of contraception (as described in Section 8.1.3, Contraception and Pregnancy Avoidance Measures) during the study and for 30 days following the last dose of study medication.
  2. Evidence of active infection, unless the medical monitor and Investigator agree that the subject is appropriate for this study.
  3. Current or past history of chronic disease including, but not limited to, gastrointestinal, cardiovascular, cerebrovascular, pulmonary, neurologic, renal, or liver disease.
  4. Diastolic blood pressure ≤55 mmHg or systolic blood pressure ≤100 mmHg at Screening.
  5. Clinically important or significant conduction abnormalities on ECG at Screening (including QTcF intervals >450 msec) and/or history of long QT syndrome. It is acceptable to repeat the ECG to confirm findings.

  8. Serum transaminase (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) levels >1.5X the upper limit of normal (ULN). If a subject presents with an abnormal AST and/or ALT results, the subject may be re-scheduled or the test may be repeated once at the discretion of the Investigator.
  9. Serum creatinine level ≥1.50 mg/dL. It is acceptable to repeat the test to confirm findings.
  10. Chronic daily medication use, except once daily over the counter multi-vitamin supplement.
  11. Subject has taken any prescription medication within 7 days (or 5 half-lives, whichever is longer) prior to admission to the CRU.
  12. Herbal supplements within 48 hours prior to dosing of study drug.
  13. History of regular alcohol consumption exceeding 14 drinks/week (1 drink = 5 ounces of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) within 6 months of Screening.
  14. Any history of alcohol or drug dependence within the previous year prior to Screening. Self-reported substance or alcohol dependence (excluding nicotine or caffeine) within the past 2 years, and/or have ever been in a substance or alcohol rehabilitation program to treat their substance or alcohol dependence

  22. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the Investigator's judgment, would make the subject inappropriate for study entry.
