  • Ages 18 to 60 years
  • All sexes
  • No healthy volunteers

  • Women were eligible if not pregnant or breast-feeding.
  • Women of childbearing potential (that is, not surgically sterile or confirmed post menopausal) must have had confirmed negative pregnancy tests. All participants must practice a medically acceptable form of contraception.

Who cannot join

  • Human immunodeficiency virus or hepatitis B virus co-infection known cirrhosis.
  • Prior history of clinical hepatic decompensation (ascites, jaundice, encephalopathy, or variceal hemorrhage), alcoholic or other forms of chronic liver disease, evidence of hepatocellular carcinoma (α-fetoprotein > 50 nanograms/mL), creatinine clearance < 80 mL/minute (using Cockcroft-Gault equation), hemoglobin < 10 g/dL, neutrophils < 1500/mm^3, and abnormal thyroid function tests (thyroid stimulating hormone > 2.5 microIU/mL, free T4 > ULN), or, a positive test result for illicit drugs, alcohol, or drug abuse within the past 12 months.
  • Participants who have had significant gastrointestinal, thyroid, renal, cardiovascular, pulmonary, oncologic, or neurological disease, or who are currently receiving immunomodulators (corticosteroids), investigational, nephrotoxic or hepatotoxic drugs (for example, phenytoin, carbamazepine, isonicotinic acid hydrazide, azole anti-fungal agents such as ketoconazole, and aminoglycoside antibiotics), non-steroidal anti-inflammatory agents, ibuprofen or acetaminophen (on a daily basis) will also be excluded.

About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Dose-Escalation Study to Investigate the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of Multiple Doses of ACH-0137171 in Subjects With Chronic Hepatitis C Infection

The purpose of this study was to investigate the safety, tolerability, pharmacokinetics (PK), and antiviral activity of multiple doses of ACH-0137171 in participants with chronic hepatitis C virus (HCV) infection.

Read the detailed description

This was a randomized, double-blind, placebo-controlled, dose-escalation study of ACH-0137171 in participants with chronic HCV infection.

Sequential cohorts of 10 participants were randomized (8:2) to receive multiple doses of ACH-0137171 or placebo for 4 days (Days 1 through 4) with a single dose on Day 5 followed by a complete PK profile. Dosing was 300-600 milligrams (mg) administered either every 12 hours or every 6 hours (maximum daily dose of 2400 mg). All doses were administered with food.

The dose cohorts were as follows:

Study Schema:

Cohort 1: 300 mg ACH-0137171/placebo every 12 hours (600 mg/day) Cohort 2: 300 mg ACH-0137171/placebo every 6 hours (1200 mg/day) Cohort 3: 600 mg ACH-0137171/placebo every 6 hours (2400 mg/day)

A full review of all safety data will occur following each cohort. Depending on the data, the Sponsor, in consultation with the Principal Investigator(s), may consider modifying the planned dose escalation. The Sponsor may choose to interject an intermediate dose cohort between 2 planned dose escalations or repeat a given dose level, or extend the dosing period, or add an additional cohort. If a similar Grade 3 or 4 adverse event occurs in 3 or more participants and was considered to be at least possibly related to the study drug, escalation to a higher dose will not occur.

Serial HCV ribonucleic acid (RNA) measurements, PK measurements of plasma concentrations of ACH-0137171, and periodic safety monitoring occurred on Days 1 through 5. Additional HCV RNA and PK measurements were taken on Days 6 through 9. Follow-up safety evaluations will be completed 14 days after the last study drug administration (that is, on Days 12 and 19).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To assess the short-term safety and tolerability of multiple, escalating, oral doses of ACH-0137171 in subjects with chronic hepatitis C infection.

  2. To characterize the plasma pharmacokinetics of ACH-0137171 following administration of multiple, escalating, oral doses in subjects with chronic hepatitis C infection.

  3. To assess the antiviral activity of ACH-0137171 as measured by plasma HCV RNA levels in subjects with chronic hepatitis C infection following administration of multiple, escalating, oral doses.

  4. To assess the correlation between antiviral activity and pharmacokinetic parameters.

Secondary outcomes (2)
  1. To perform viral dynamic and pharmacodynamic modeling of ACH 0137171 virologic response.

  2. To assess the biochemical response of ACH-0137171 as measured by the change from baseline of serum ALT and AST levels.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ACH-0137171 in people with HCV Infection, run by Alexion Pharmaceuticals, Inc. at 9 sites in 3 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Germany, Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Nephrotoxicity). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To assess the short-term safety and tolerability of multiple, escalating, oral doses of ACH-0137171 in subjects with chronic hepatitis C infection.. The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2022.
