NCT03253471

Brief Summary

This randomized, double-blind, placebo-controlled, 3-part study will assess the safety, tolerability, pharmacokinetics (PK), and antiviral activity (Part 3 only) of orally administered AL-611 in healthy volunteers (HV; Parts 1-2) and subjects with CHC (Part 3). Part 1: HV will receive 1 of 5 single ascending doses (SAD) of AL-611 Part 2: Eight HV from Cohort 3 in Part 1 are planned to receive a second single dose of AL-611 or placebo (as per their randomized assignment in Part 1) in a fed state after a washout period Part 3: Subjects with CHC infection will receive 1 of 3 planned multiple ascending doses (MAD)

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject has provided written consent.
  • In the investigator's opinion, the subject is able to understand and comply with protocol requirements, instructions, and protocol stated restrictions and is likely to complete the study as planned.
  • Except in compensated cirrhosis (cirrhosis cohorts only) and diagnosis of HCV (Part 3 only), subject is in good health as deemed by the investigator, based on the findings of a medical evaluation including medical history, physical examination, laboratory tests, and ECG.
  • Male or female, 18-60 years of age for HV and 18-70 years of age for subjects with CHC.
  • Body mass index (BMI) 18-30 kg/m2, inclusive, for HV and 18-35 kg/m\^2, inclusive, for subjects with CHC. The minimum weight is 50 kg in both populations.
  • A female subject is eligible to participate in this study if she is of non-childbearing potential (defined as females with a documented tubal ligation, bilateral oophorectomy, or hysterectomy) or postmenopausal (defined as 12 months of spontaneous amenorrhea and follicle stimulating hormone (FSH) level within the laboratory's reference range for postmenopausal females).
  • If male, subject is surgically sterile or practicing specific forms of birth control until 6 months after the end of the study. Male subjects must agree to refrain from sperm donation from start of dosing through 6 months after the completion of study drug administration.
  • Subject agrees to refrain from blood donation from screening until 56 days after the last study visit.
  • For HV, estimated glomerular filtration rate (eGFR) in the normal range as determined by modification of diet in renal disease (MDRD) formula. For CHC (Part 3) eGFR\>60ml/min/1.73m\^2 as determined by MDRD (alternative calculations (eg, Cockroft-Gault) may be permissible, if approved by the Sponsor).
  • Subjects must have GT1 or GT3 CHC (or GT1-6 for Part 3 optional cohorts) infection identified at screening.
  • Documentation of HCV infection for greater than 6 months before randomization as defined by either documented HCV serology demonstrating the presence of anti-HCV antibodies at least 6 months before randomization or documented presence of HCV RNA at least 6 months before randomization.
  • Screening HCV RNA viral load ≥50,000 IU/mL (except for subjects with compensated cirrhosis, who may have HCV RNA viral load ≥10\^4 IU/mL) using Ampliprep COBAS® Taqman® HCV Test 2.0
  • Cirrhotic subjects in Part 3 must have compensated cirrhosis AND meet the Child-Pugh Class A definition AND have a screening Fibroscan with a liver stiffness score\>12.5 kPa.

You may not qualify if:

  • History or other clinical evidence of significant or unstable cardiac disease (eg, angina, congestive heart failure, myocardial infarction, diastolic dysfunction, significant arrhythmia (eg, long QT syndrome, torsades de pointes), coronary heart disease), moderate to severe valvular disease or poorly controlled hypertension at screening.
  • Family history of prolonged QT syndrome (eg, torsade de pointes) or sudden cardiac death.
  • Clinically significant abnormal screening ECG findings (eg, PR \>220 msec, QRS interval \>120 msec or corrected QT interval (QTcF) \>450 msec for male subjects and \>470 msec for female subjects).
  • Participation in either an investigational drug trial or an investigational vaccine trial within 30 days or 5 half lives (whichever is longer) prior to starting study medication.
  • Clinically significant blood loss or elective blood donation of significant volume (ie, \>500 mL) within 60 days prior to screening; \>1 unit of plasma within 7 days prior to screening.
  • Unwilling to abstain from alcohol for 48 hours prior to the start of dosing through the study completion visit.
  • History of regular alcohol intake \>14 units per week of alcohol for females and \>21 units per week for males (one unit is defined as 10 g alcohol) within 3 months of randomization
  • The subject has a positive alcohol test at screening or on Day -2.
  • Hypersensitivity to the active substance or to any of the excipients of AL-611
  • Abnormal (using local normal range) heart rate, respiratory rate, temperature or blood pressure (BP) values (evaluated in a semi-recumbent or recumbent position after 5 minutes of rest). One repeat measurement after an additional \~5 minutes of rest is permitted. In addition, a repeat measurement performed on a separate day is also permitted.
  • History of regular use of tobacco (ie, ≥10 cigarettes per day or equivalent for alternative nicotine products (eg, e cigarettes)) within 3 months of randomization.
  • The subject has a positive drug screen during screening or on Day -2. For CHC, prescribed medications with a stable dose for at least 21 days may be considered by the Investigator and Sponsor Medical Monitor; cannabis is permitted.
  • Abnormal screening laboratory results that are considered clinically significant by the investigator or as specified in the protocol.
  • History of clinical hepatic decompensation, eg, variceal bleeding, spontaneous bacterial peritonitis, ascites, hepatic encephalopathy or active jaundice (within the last year).
  • Except subjects with compensated cirrhosis, a liver biopsy within 2 years that demonstrates cirrhosis (Knodell score \>3, Metavir score \>3, Ishak score \>4) or a screening Fibroscan liver stiffness score \>12.5 kPa.
  • +2 more criteria
