Hepatitis C, HIV Infections
Conditions
Brief summary
HIV and hepatitis C virus (HCV) infection are diseases that share the same risk factors and routes of transmission. For this reason, many people infected with HIV are also infected with HCV. Interferon (IFN) is a drug used to treat HCV; however, in people coinfected with HIV and HCV, IFN treatment often does not work well and can cause unwanted side effects. The purpose of this study was to evaluate the safety, tolerability, and effectiveness of IFN-free HCV treatment in HIV/HCV coinfected adults who were taking antiretroviral (ARV) therapy.
Detailed description
This study evaluated the safety, tolerability, and effectiveness of a combination of drugs to treat HCV in adults who were coinfected with HIV and HCV. The three drugs were paritaprevir/ritonavir/ombitasvir (PTV/r/OBT), dasabuvir (DSV), and ribavirin (RBV). In version 1 of the study, RBV was given to all participants. After revision in version 2, RBV was given only to participants with HCV genotype 1a; participants with HCV genotype 1b did not receive RBV. This study enrolled HCV genotype 1a or 1b and HIV-1 coinfected participants (HCV treatment-naïve or HCV treatment-experienced) who were on a concurrent integrase inhibitor (INI)-based (raltegravir \[RAL\] or dolutegravir \[DTG\]) or protease inhibitor (PI)-based (darunavir \[DRV\] or atazanavir \[ATV\]) ART regimen. (The ART regimens were not provided by the study.) The participants were assigned to one of four cohorts (Cohorts A, B, C, and D). Participants in Cohorts A and B were on INI-based ART; participants in Cohorts C and D, on PI-based ART. For each group, the study proceeded in two steps: Step 1: on-HCV treatment and Step 2: post-HCV treatment follow-up. Participants in Cohorts A and C received the HCV drugs for 24 weeks; participants in Cohorts B and D, for 12 weeks. The target sample size goal was a total of 100 participants, with 25 participants per cohort. Total study duration was up to 48 weeks. During Step 1 (on-HCV treatment), all participants had study visits at Weeks 2, 4, 6, 8, 10, and 12. Participants in Cohorts A and C had additional Step 1 study visits at Weeks 16, 20, and 24. All participants had Step 2 (post-treatment follow-up) study visits 4, 12, and 24 weeks after registration to Step 2. Participants in Cohorts B and D had an additional Step 2 visit 36 weeks after registration to Step 2. All study visits included a brief physical exam and blood collection. Select study visits included pregnancy testing for participants able to become pregnant, an electrocardiogram (EKG), an IFN gamma-induced protein 10 (IP-10) test, and collection of plasma samples. Participants were able to coenroll in one of two optional substudies. In one substudy, participants attended two study visits at entry/Day 0 and Week 4 for 12-hour intensive pharmacokinetic (PK) sampling. In another substudy, participants underwent liver biopsies at two time points and PK sampling. Study accrual was terminated early and participants who enrolled continued on study until completion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Sustained Virologic Response at 12 Weeks After HCV Treatment Discontinuation (SVR12) | At 12 weeks after last dose of HCV study treatment. The duration for study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | SVR12 was defined as HCV RNA less than the assay LLOQ (\<15 IU/mL) at 12 weeks post HCV treatment discontinuation. A two-sided 90% confidence interval was calculated for the percentage of participants with SVR12 response using Clopper-Pearson method. For those whose HCV early responses prior to SVR12 evaluation met the guidelines for HCV Virologic Failure (VF), their SVR12 outcome was defined as non-response. Those missing a HCV RNA result from the week 12 post HCV treatment discontinuation visit (and missing all subsequent evaluations) were considered non-responders. However, if HCV RNA evaluations subsequent to week 12 post treatment discontinuation were non-missing, then the first HCV RNA subsequent to week 12 post treatment discontinuation was instead used to define the primary outcome. |
| Number of Participants With an Occurrence of Serious Adverse Events (SAEs) as Defined by International Conference on Harmonisation (ICH) Criteria | From treatment initiation to 30 days post date of last dose of HCV study treatment (whether planned or premature discontinuation). The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | Participants who experienced at least one observed SAEs as defined by ICH after initiating HCV study treatment through 30 days post date of last dose of HCV study treatment. |
| Number of Participants Who Prematurely Discontinued HCV Study Treatment for Any Reason Other Than HCV Virologic Failure (VF) | From treatment initiation to either 24 weeks (for Cohort A and C) or 12 weeks (for Cohort B and D). The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | HCV VF was defined as follows: confirmed increase from nadir in HCV RNA (defined as two consecutive HCV RNA measurements of \>1 log10 IU/mL above nadir) at any time point; failure to achieve HCV RNA \<LLOQ (\<15 IU/mL) by week 6; confirmed HCV RNA ≥LLOQ (defined as two consecutive HCV RNA measurements ≥LLOQ (≥15 IU/mL)) at any point after HCV RNA \<LLOQ during HCV treatment |
| Number of Participants With an Occurrence of Signs/Symptoms Grade 3 or Higher | From treatment initiation to 30 days post date of last dose of HCV study treatment (whether planned or premature discontinuation). The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | Participants with signs/symptoms of grade 3 or higher post treatment initiation. Participants with grade 3 sign/symptom prior to treatment initiation must have had one grade higher than pre-treatment to meet this outcome. Severity grading was based on DAIDS AE Grading Table, Version 1.0. |
| Number of Participants With an Occurrence of Diagnoses Leading to Premature HCV Study Treatment or HIV-1 Antiretroviral (ARV) Discontinuation. | From treatment initiation to end of study follow-up at 48 weeks.The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. The duration for ARV treatment for all cohorts was 48 weeks. | Participants who had diagnoses leading to premature HCV study treatment or HIV-1 ARV discontinuation post treatment initiation. |
| Number of Participants With an Occurrence of Laboratory Abnormality Grade 3 or Higher. | From treatment initiation to 30 days post date of last dose of HCV study treatment (whether planned or premature discontinuation). The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | Participants with an observed laboratory abnormalities grade 3 or higher post treatment initiation. If entry (pre-treatment) lab result was grade 3, then a grade 4 result was required to meet this outcome. Severity grading was based on DAIDS AE Grading Table, Version 1.0. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With HCV Mutations Conferring Resistance to Any Component of the HCV Treatment Regimen | From treatment initiation to 12 weeks post date of last dose of HCV study treatment. The duration for HCV study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | Study team decided to remove this secondary outcome measure due to reduced interest in study treatment as a result of development and approval of newer DAA's. |
| Number of Participants Who Experienced HIV-1 Virologic Failure (VF) | From treatment initiation to 4 weeks after last dose of HCV study treatment. HIV-1 RNA was measured at weeks 2, 4, 6, 8, 10, 12, 16, 20, 24, and 28. The durations for HCV study treatment for Cohorts A/C and Cohorts B/D were 24 and 12 weeks, respectively. | HIV-1 VF was defined as two consecutive HIV-1 RNA results ≥ 200 copies/mL. |
| Percentage of Participants With Sustained Virologic Response at 24 Weeks After HCV Treatment Discontinuation (SVR24) | At 24 weeks after the date of last dose of HCV study treatment. The duration for study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively. | SVR24 was defined as HCV RNA less than the assay LLOQ (\<15 IU/mL) at 24 weeks post treatment discontinuation. A two-sided 90% confidence interval was calculated for the percentage of SVR24 response using method of Clopper-Pearson. For those whose HCV early responses prior to SVR24 evaluation met the guidelines for HCV VF, their SVR24 outcome was defined as non-response. Those missing a HCV RNA result from the week 24 post HCV treatment discontinuation visit (and missing all subsequent evaluations) were considered non-responders. However, if HCV RNA evaluations subsequent to week 24 post treatment discontinuation were non-missing, then the first HCV RNA subsequent to week 24 post treatment discontinuation was instead used to define the primary outcome. |
| Number of Participants With Selected HIV-1 Resistance Mutations Among Participants Who Experience HIV-1 Virologic Failure (VF) | At confirmation of HIV-1 virologic failure. | Participants with one or more genotype mutations in protease conferring major resistance to any HIV-1 Protease Inhibitors (PI) antiretroviral drug, from a plasma sample drawn following confirmed HIV-1 VF outcome. |

Primary
Percentage of Participants With Sustained Virologic Response at 12 Weeks After HCV Treatment Discontinuation (SVR12)
SVR12 was defined as HCV RNA less than the assay LLOQ (\<15 IU/mL) at 12 weeks post HCV treatment discontinuation. A two-sided 90% confidence interval was calculated for the percentage of participants with SVR12 response using Clopper-Pearson method. For those whose HCV early responses prior to SVR12 evaluation met the guidelines for HCV Virologic Failure (VF), their SVR12 outcome was defined as non-response. Those missing a HCV RNA result from the week 12 post HCV treatment discontinuation visit (and missing all subsequent evaluations) were considered non-responders. However, if HCV RNA evaluations subsequent to week 12 post treatment discontinuation were non-missing, then the first HCV RNA subsequent to week 12 post treatment discontinuation was instead used to define the primary outcome.
Time frame: At 12 weeks after last dose of HCV study treatment. The duration for study treatment for Cohorts A and C and Cohorts B and D was 24 and 12 weeks, respectively.
Population: Participants who initiated study treatment.

Percentage of Participants With Sustained Virologic Response at 24 Weeks After HCV Treatment Discontinuation (SVR24)
SVR24 was defined as HCV RNA less than the assay LLOQ (\<15 IU/mL) at 24 weeks post treatment discontinuation. A two-sided 90% confidence interval was calculated for the percentage of SVR24 response using method of Clopper-Pearson. For those whose HCV early responses prior to SVR24 evaluation met the guidelines for HCV VF, their SVR24 outcome was defined as non-response. Those missing a HCV RNA result from the week 24 post HCV treatment discontinuation visit (and missing all subsequent evaluations) were considered non-responders. However, if HCV RNA evaluations subsequent to week 24 post treatment discontinuation were non-missing, then the first HCV RNA subsequent to week 24 post treatment discontinuation was instead used to define the primary outcome.
