A Study of TMC435 in Genotype 1, Hepatitis C-infected Patients Who Relapsed After Previous Interferon (IFN)-Based Therapy

The table below shows the percentage of participants with an SVR12 defined as participants with undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) at the end of treatment (Week 24 or 48) who also had undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) 12 weeks after the last dose of treatment (Week 36 or 60).

Time frame: Week 36 or 60

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

The table below shows the median (range) AUC24h values for TMC435 for all participants who received TMC435 for up to 12 weeks. Overall is the median exposure estimate using all available data for each participant in the study. Sparse blood samples were collected during the study (blood sampling times were 3 and 5 hours post- dose at Week 2 and Week 8 and pre-dose and 2 hours post-dose at Week 4 and Week 12).

Time frame: Overall (blood sampling times were 3 and 5 hours post- dose at Week 2 and Week 8 and pre-dose and 2 hours post-dose at Week 4 and Week 12)

Population: Pharmacokinetic (PK) analysis was performed in the PK population defined as all participants from whom sparse blood samples were drawn and who received at least 1 dose of study medication.

The table below shows median (range) TMC435 predose plasma concentration (C0h) values and the TMC435 maximum plasma concentration (Cmax) values for all participants who received TMC435 for up to 12 weeks. Overall is the median exposure estimate using all available data for each participant in the study.Sparse blood samples were collected during the study (blood sampling times were 3 and 5 hours post- dose at Week 2 and Week 8 and pre-dose and 2 hours post-dose at Week 4 and Week 12).

Time frame: Overall (blood sampling times were 3 and 5 hours post- dose at Week 2 and Week 8 and pre-dose and 2 hours post-dose at Week 4 and Week 12)

Population: Pharmacokinetic (PK) analysis was performed in the PK population defined as all participants from whom sparse blood samples were drawn and who received at least 1 dose of study medication.

The table below shows the number of participants who demonstrated viral relapse, defined as undetectable Hepatitis C Virus Ribonucleic Acid (HCV RNA) at end of treatment (EOT) and detectable HCV RNA during follow-up or detectable HCV RNA at the time points of sustained virologic response (SVR) assessment . The incidence of viral relapse was calculated for participants with undetectable HCV RNA levels at EOT and with at least one follow-up HCV RNA measurement.

Time frame: Up to 72 weeks

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

The table below shows the number of participants with abnormal ALT levels at baseline (Day 1) who achieved normalization of ALT levels (defined as an ALT value less than or equal to the Upper Limit of Normality \[ie, 40 IU/mL\] at EOT). At baseline, 15/49 participants had abnormal ALT levels.

Time frame: EOT (Week 24 or 48)

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

Viral breakthrough was defined as a confirmed increase of greater than 1 log10 IU/mL in plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels from the lowest level reached or a confirmed value of plasma HCV RNA of \> 2.0 log10 IU/mL in particpants whose plasma HCV RNA level had previously been below 1.2 log10 IU/mL detectable or undetectable during the treatment period. The table below shows that no viral breakthrough was noted in any participants during the treatment period of the study.

Time frame: Day 1 until end of treatment (EOT [Week 24 or 48])

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

The table below shows the percentage of participants with greater than or equal to 2 log10 IU/mL drop from baseline in plasma HCV RNA at each time point during treatment, at the end of treatment (Week 24 or 48), and post-treatment follow-up.

Time frame: Days 3 and 7, Weeks 2, 3, 4, 8, 12, 16, 20, 24, 28, 36, 48, 60, 72, EOT, and follow-up (FU) Weeks 4, 12, and 24

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

The table below shows the percentage of participants with a SVR24 defined as participants with undetectable plasma Hepatitis C Virus Ribonucleic Acid (HCV RNA) at the end of treatment (Week 24 or 48) and at 24 weeks after the last dose of treatment (Week 48 or 72).

Time frame: Week 48 or 60

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.

The table below shows the percentage of participants with undetectable HCV RNA (defined as less than 1.2 log10 IU/mL during treatment at Weeks 4, 12, 24, 36, 48, 60, 72, and at EOT \[Week 24 or 48\]).

Time frame: Weeks 4, 12, 24, 36, 48, 60, 72, and at EOT

Population: The Full Analysis Set (FAS) consisted of all participants who received at least one dose of study drug during the study except for those who did not meet the major eligibility criteria for the study and participants who did not have efficacy data available after treatment with study medication.
