A Study to Evaluate ABT-450 With Ritonavir (ABT-450/r) and ABT-267 in Japanese Adults With Chronic Hepatitis C Virus Infection

30 aprile 2018 aggiornato da: AbbVie (prior sponsor, Abbott)

A Phase 2 Study to Evaluate the Safety, Tolerability, Antiviral Activity, and Pharmacokinetics of ABT-450 With Ritonavir (ABT-450/r) and ABT-267 in Japanese Adults With Chronic Hepatitis C Virus Infection

This study evaluated the safety, tolerability, antiviral activity, and pharmacokinetics of ABT-450 (also known as paritaprevir) with ritonavir (ABT-450/r) and ABT-267 (also known as ombitasvir) in adult Japanese patients with chronic hepatitis C virus genotype 1b (HCV GT1b) or genotype 2 (HCV GT2) infection who were previous treated with pegylated interferon/ribavirin (pegIFN/RBV).

Descrizione dettagliata

This multicenter, randomized, open-label, parallel-arm, combination treatment study consisted of a Treatment and Post-treatment Phase, divided into 2 cohorts: 1) chronic HCV GT1b- infected, pegIFN/RBV treatment-exposed Japanese adults; and 2) HCV GT2-infected, pegIFN/RBV treatment-exposed Japanese adults. The Treatment Phase evaluated the antiviral activity, safety, and pharmacokinetics of a range of ABT-450/r and ABT-267 doses for 12 to 24 weeks. The Post-treatment Phase evaluated the evolution and persistence of viral resistance to ABT-267 and ABT-450.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Percentage of Participants With Sustained Virologic Response 24 Weeks After Treatment (SVR24)
Lasso di tempo: 24 weeks after last dose of study drug
The percentage of participants with SVR24 (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ] 24 weeks after the last dose of study drug). The LLOQ for the assay was 25 IU/mL.
24 weeks after last dose of study drug
Number of Participants With Adverse Events (AEs)
Lasso di tempo: TEAEs: up to 16 weeks for the 12-week treatment groups and up to 28 weeks for the 24-week treatment groups; SAEs: up to 65 weeks for the 12-week treatment groups and up to 77 weeks for the 24-week treatment groups.
An AE is any untoward medical occurrence, which does not necessarily have a causal relationship with treatment. A serious adverse event (SAE) is an AE that results in death, is life-threatening, results in or prolongs hospitalization, results in congenital anomaly, persistent or significant disability/incapacity, spontaneous or elective abortion, or requires intervention to prevent a serious outcome. AEs were rated for severity as either Mild: transient and easily tolerated; Moderate: causes discomfort and interrupts usual activities; or Severe: causes considerable interference with usual activities, may be incapacitating or life-threatening. AEs related to study drug were assessed as being either probably or possibly related by the investigator. Treatment-emergent AEs (TEAEs) were collected from the first dose of study drug administration to 30 days after last dose; SAEs were collected from the time that informed consent was obtained to 30 days after last dose.
TEAEs: up to 16 weeks for the 12-week treatment groups and up to 28 weeks for the 24-week treatment groups; SAEs: up to 65 weeks for the 12-week treatment groups and up to 77 weeks for the 24-week treatment groups.

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo

Lasso di tempo: 12 weeks after last dose of study drug
The percentage of participants with SVR12 (plasma HCV RNA level < LLOQ 12 weeks after the last dose of study drug). The LLOQ for the assay was 25 IU/mL.
12 weeks after last dose of study drug
Percentage of Participants With End of Treatment (EOT) Response
Lasso di tempo: 12 or 24 weeks after first dose of study drug
The percentage of participants with EOT response (plasma HCV RNA level < LLOQ at week 12 for the 12-week duration arms and Week 24 for the 24-week duration arms12). The LLOQ for the assay was 25 IU/mL.
12 or 24 weeks after first dose of study drug
