Efficacy and Safety of Combinations of AL-335, Odalasvir (ODV) and Simeprevir (SMV) in the Treatment of Chronic Hepatitis C Infection

November 19, 2019 updated by: Janssen Research & Development, LLC

A Phase 2b, Multicenter, Randomized, Open-label Study to Investigate the Efficacy, Safety and Pharmacokinetics of Different Treatment Regimens of AL-335, Odalasvir, and Simeprevir in Treatment-naive and Treatment-experienced Subjects With Chronic Hepatitis C Virus Genotype 1, 2, 4, 5, and 6 Infection Without Cirrhosis

The purpose of this study is to evaluate the efficacy (proportion of subjects with SVR12), safety, tolerability and pharmacokinetics of an 8- and 6-week treatment regimen of AL-335, odalasvir (ODV) and simeprevir (SMV) in chronic HCV genotype 1, 2, 4, 5 or 6 infected subjects without cirrhosis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase 2b multicenter study. The study will include a screening period of maximum 6 weeks, a treatment period of 6 or 8 weeks and a 24-weeks post-treatment follow-up period. The total study duration for each subject will be 36 to 38 weeks. This study investigates a 3 direct-acting antiviral agent (DAA) combination of AL-335 (HCV NS5B inhibitor), odalasvir (ODV) (a second generation HCV NS5A inhibitor) and simeprevir (SMV) (HCV NS3A4 protease inhibitor). The results of this study will enable the selection of treatment and duration to be further developed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 12 Weeks After End of Treatment (EOT) (SVR12)
Time Frame: Week 12 (Follow-Up Phase)
The SVR 12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) less than (<) lower limit of quantification (LLOQ; 15 international unit per milliliter [IU/mL]) detectable or undetectable 12 weeks after actual EOT.
Week 12 (Follow-Up Phase)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 24 Weeks After End of Treatment (SVR24)
Time Frame: Week 24 (Follow-Up Phase)
The SVR24 was defined as HCV RNA <LLOQ (detectable or undetectable) 24 weeks after End of Treatment (EOT).
Week 24 (Follow-Up Phase)
Number of Participants With Viral Relapse
Time Frame: End of Treatment up to Week 24 (Follow up phase)
Viral Relapse: Participants who did not achieve SVR12, with HCV RNA <LLOQ at the EOT and confirmed HCV RNA greater than or equal to (>=) LLOQ during follow-up.
End of Treatment up to Week 24 (Follow up phase)
Number of Participants With Late Viral Relapse
Time Frame: Up to Week 24 (Follow-up Phase)
Late Viral Relapse: Participants who achieved SVR12 but had confirmed HCV RNA>=LLOQ afterwards during follow-up.
Up to Week 24 (Follow-up Phase)
Percentage of Participants With On-treatment Failure
Time Frame: EOT up to Week 12 (Follow up Phase)
On-treatment failure: Participants who did not achieve SVR12 and with confirmed HCV RNA>=LLOQ at the End of Treatment (EOT).
EOT up to Week 12 (Follow up Phase)
Percentage of Participants With Sustained Virologic Response 4 Weeks After End of Treatment (EOT)
Time Frame: Week 4 (Follow-Up Phase)
The SVR 4 was defined as participants were considered to have reached SVR4, if 4 weeks after the actual EOT, HCV RNA was <LLOQ (detectable or undetectable).
Week 4 (Follow-Up Phase)
