Study Endpoints

Primary Endpoints

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Day 11 (Cohort A): Full Analysis Set
Baseline, Day 11

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (lower limit of quantification \[LLOQ\] = 12 international unit per milliliter \[IU/mL\]). Baseline value calculated as an average of screening, Day 0 and Day 1 (0 hour) measurements. Change from baseline in plasma log10 HCV RNA was calculated for all participants after the last day of dosing (Day 11 for Cohort A).

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Day 11 (Cohort A): Modified Analysis Set
Baseline, Day 11

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (LLOQ = 12 IU/mL). Baseline value calculated as an average of screening, Day 0 and Day 1 (0 hour) measurements. Change from baseline in plasma log10 HCV RNA was calculated for all participants after the last day of dosing (Day 11 for Cohort A).

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Day 4 (Cohort B): Full Analysis Set
Baseline, Day 4

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (LLOQ = 12 IU/mL). Baseline value calculated as an average of screening, Day 0 and Day 1 (0 hour) measurements. Change from baseline in plasma log10 HCV RNA was calculated for all participants after the last day of dosing (Day 4 for Cohort B).

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Day 4 (Cohort B): Modified Analysis Set
Baseline, Day 4

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (LLOQ = 12 IU/mL). Baseline value calculated as the average of screening, Day 0 and Day 1 (0 hour) measurements. Change from baseline in plasma log10 HCV RNA was calculated for all participants after the last day of dosing (Day 4 for Cohort B).

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Nadir: Full Analysis Set
Baseline, Nadir (lowest HCV RNA level), assessed up to Day 11 for Cohort A and Day 4 for Cohort B

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (LLOQ = 12 IU/mL). Change from baseline in plasma Log10 HCV RNA at nadir signified the maximum change observed during the study.

Change From Baseline in Plasma Log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Nadir: Modified Analysis Set
Baseline, Nadir (lowest HCV RNA level), assessed up to Day 11 for Cohort A and Day 4 for Cohort B

Plasma HCV RNA levels were quantified using the Abbott RealTime HCV assay (LLOQ = 12 IU/mL). Change from baseline in plasma Log10 HCV RNA at nadir signified the maximum change observed during the study.

Frequently asked questions about Small Molecule Agent

What is Small Molecule Agent used for in Hepatitis, Chronic?

Small Molecule Agent is an investigational small molecule being studied for the treatment of chronic hepatitis, specifically chronic Hepatitis C Virus infection. It is a direct antiviral agent intended to reduce viral activity in infected subjects. The drug is currently in Phase 1 clinical development and is not yet approved for any use.

Who makes Small Molecule Agent?

Small Molecule Agent is being developed by Pfizer, Inc., a biopharmaceutical company listed on the New York Stock Exchange under the ticker symbol PFE. The company is conducting clinical trials to evaluate the drug's antiviral activity in patients with chronic Hepatitis C Virus infection.

What phase is Small Molecule Agent in?

Small Molecule Agent is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities. The drug is being studied for its antiviral activity and safety in subjects with chronic Hepatitis C Virus infection, with one completed Phase 1 trial.

What clinical trials is Small Molecule Agent in?

Small Molecule Agent has one completed clinical trial, identified as NCT00671671. This Phase 1 study evaluated the antiviral activity of the drug at multiple doses in subjects with chronic Hepatitis C Virus infection. The trial enrolled 20 participants in the United States and was controlled but not randomized or double-blinded.

Is Small Molecule Agent the same as a direct antiviral agent?

Small Molecule Agent is described as a small molecule direct antiviral agent. This means it is designed to directly target and inhibit viral replication. In the clinical trial context, it is being evaluated for its antiviral activity against chronic Hepatitis C Virus infection, though specific molecular targets have not been disclosed.
