Trial Outcomes & Findings for An Exploratory Study of Telaprevir in Treatment-Naive Participants With Chronic Genotype 4 Hepatitis C Virus Infection (NCT NCT00580801)

NCT ID: NCT00580801

Last Updated: 2013-09-09

Results Overview

The plasma HCV RNA levels were used to assess the antiviral activity which included viral response as either undetectable HCV RNA (that is no HCV target was detected in the plasma sample) or less than 25 International unit per milliliter (IU/mL) of HCV RNA (that is Plasma sample contained HCV RNA at a concentration below the limit of quantification \[LLOQ=25 IU/mL\] of the viral load assay). Plasma HCV RNA levels were measured using the COBAS TaqMan HCV test Version 2.0. This assay used real-time reverse transcription-polymerase chain reaction (RT-PCR) methodology.

Telaprevir 750 milligram (mg) tablet was administered three times a day orally for 2 weeks and after that pegylated-interferon-alfa-2a (180 microgram \[mcg\] subcutaneous injection \[injected under the skin by way of a needle\], once weekly) and ribavirin (1000-1200 mg as oral tablet daily) was administered from Week 2 to 50.
Telaprevir+Pegylated-interferon-alfa-2a+Ribavirin
n=7 Participants
Telaprevir 750 mg tablet was administered three times a day orally for 2 weeks along with pegylated-interferon-alfa-2a (180 mcg subcutaneous injection, once weekly) and ribavirin (1000-1200 mg as oral tablet daily) was administered from Week 1 to 48.
Placebo+Pegylated-interferon-alfa-2a+Ribavirin
Matching placebo tablet to telaprevir was administered three times a day orally for 2 weeks along with pegylated-interferon-alfa-2a (180 mcg subcutaneous injection, once weekly) and ribavirin (1000-1200 mg as oral tablet daily) was administered from Week 1 to 48.
Minimum Serum Concentration (Cmin) of Telaprevir on Day 15
1639 Nanogram/milliliter (ng/mL)
Standard Deviation 447.7
2100 Nanogram/milliliter (ng/mL)
Standard Deviation 796.3

SECONDARY outcome

Timeframe: Pre-dose, 0.5, 1, 2, 3, 4, 6 and 8 hours post-dose on Day 1 and 15

Population: ITT population included any randomized participant who received at least 1 dose of telaprevir/placebo. "n" signifies number of participants with data for this measure at the specified time point for each arm group respectively.

The tmax is the time to reach maximum observed serum concentration of telaprevir and then pegylated-interferon-alfa-2a+Ribavirin (reference) and pegylated-interferon-alfa-2a+Ribavirin (test).

SECONDARY outcome

Timeframe: Pre-dose, 0.5, 1, 2, 3, 4, 6 and 8 hours post-dose on Day 1 and 15

Population: ITT population included any randomized participant who received at least 1 dose of telaprevir/placebo. "N" signifies those participants who were evaluated for this measure.

The Average steady-state serum concentration (Css,av) was calculated by AUC/τ at steady-state (τ=dosing interval) of telaprevir and then pegylated-interferon-alfa-2a+Ribavirin (reference) and telaprevir+pegylated-interferon-alfa-2a+Ribavirin (test).
