General information about the trial
|
|||
Main objective of the trial |
The main purpose of the study was to evaluate the durability of sustained virologic response (SVR) in subjects treated for hepatitis C virus (HCV) infection in a preceding Phase 2 or Phase 3 study who had achieved SVR at last post-therapy visit of the parent study (LPVPS).
|
||
Protection of trial subjects |
The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with Good Clinical Practices and applicable regulatory requirements. The safety assessments included monitoring of adverse events, clinical laboratory assessments (serum chemistry, hematology, coagulation, and alpha-fetoprotein), and electrocardiograms (ECGs).

Subjects who completed the last post-therapy visit of the parent study (LPVPS) (Phase 2 or Phase 3 study), in which they received a regimen containing odalasvir and AL-335 with or without simeprevir for the treatment of hepatitis C virus (HCV) infection, and who agreed to participate in this follow-up study was assessed for durability of sustained virologic response (SVR), incidence of late viral relapse, presence and long term-persistence of resistance associated substitutions (RAS) and liver disease status. SVR at the LPVPS is defined as subjects who achieved SVR 12 weeks after the end of treatment (SVR12) in the parent study, and maintained HCV ribonucleic acid (RNA) less than (<) the lower limit of quantification (LLOQ) until LPVPS. | |||||||||||||||

Number of Subjects in Each Child-Pugh Grading Category at Endpoint | ||||||||||||||||||
End point description |
Number of subjects in each child-pugh grading category at endpoint was reported.

Each measure is scored from 1 to 3, with 3 indicating most severe derangement. In subjects with cirrhosis, the sum of the scores provides the child-pugh score as followed: child-pugh A (mild): 5-6 points, child-pugh B (moderate): 7-9 points, and child-pugh C (severe): 10-15 points. All enrolled analysis set included all subjects who signed an ICF for the present study with cirrhosis at baseline.

Substantial protocol amendments (globally) |

Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
06 Nov 2017 |
The overall reason for the amendment was the decision to discontinue further development of JNJ-64294178 (a combination of three direct acting antivirals - AL-335, odalasvir , and simeprevir), and consequently, the stop of further enrollment in the current study. |
||
Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Due to the early termination of study, only 54 of planned 250 subjects were enrolled, and no subjects completed full 36-month follow-up period. Consequently, only limited long-term follow-up data was available and conclusions could not be drawn. |
