Endpoints
A primary efficacy endpoint is the durability of long-term SVR which will be evaluated
based upon the time to viral relapse. Viral relapse is defined as any subject who has
HCV RNA quantifiable and was previously TND at end of treatment and TND or TD(u)
during the follow-up period of the previous trial. Relapse would be indicated so long as
this was the same genotype of the virus seen in the parent protocol (eg. not a new
infection or re-infection (see Section 2.5). Time to relapse is defined as the time from
last dose of study therapy taken in previous trial until the date where HCV RNA is ≥25
IU/mL. The percentage of subjects who remain HCV RNA <25 IU/mL during the course
of this study will also be evaluated.
In subjects with HCV RNA ≥1000 IU/mL at entry or during the study period, HCV
sequence analysis will be performed to evaluate the presence of RAVs and the
persistence of RAVs over time.
Safety Endpoints
Safety and signs of disease progression are assessed for all subjects by physical
examination, drug-related serious adverse events, events of clinical interest, any AEs
related to protocol-specified procedures (blood draw), and laboratory tests.
Inclution Criteria
least one dose of MK-5172.
2. Subject must enroll (Visit 1) within one year of the treatment portion of their previous
MK-5172 protocol except in the circumstance where the previous protocol has a
follow-up period that is ≥1 year.
If a patient in a treatment protocol received extended follow-up (≥1 year) in the
original protocol, they may enroll in this study at the final visit of the previous
protocol.
3. Subject must be ≥ 18 years of age and willing to give written informed consent.
4. Subjects, who have consented for the trial, may also provide consent for Future
Biomedical Research. However, the subject may participate in the main trial without
participating in Future Biomedical Research.
Exclusion Criteria
entry, the subject may be excluded.
