Hepatitis C Support Group
Hepatitis C is a blood-borne viral disease which can cause liver inflammation, fibrosis, cirrhosis and liver cancer. The hepatitis C virus (HCV) is spread by blood-to-blood contact with an infected person's blood. Many people with HCV infection have no symptoms and are unaware of the need to seek treatment. Hepatitis C infects an estimated 150-200 million people worldwide.
"...MK-5172 in combination with peginterferon alfa-2b and ribavirin (PR) was evaluated versus VICTRELIS (boceprevir), 200 mg Capsules, in combination with PR in treatment-nave, non-cirrhotic patients with HCV genotype 1"

It seems to be with and without for geno 1... I think
http://www.clinicaltrials.gov/ct2/show/NCT01353911?term=mk-5172&rank=4
There are several MK-5172 studies if you'l notice. The one you originally referenced with MK-5172 & boceprevir includes interferon in every arm.
Here are the two studies side by side for an easy comparison:
1) with Boceprevir: http://www.clinicaltrials.gov/ct2/show/NCT01353911?term=mk-5172&rank=4
2) Without Boceprevir: http://www.clinicaltrials.gov/ct2/show/NCT01717326?term=mk-5172&rank=9
They're totally different studies.

Let's wish them good outcomes!
"The primary efficacy endpoint of the study was to evaluate the complete early viral response (cEVR) of four regimens of MK-5172 in combination with peginterferon alfa-2b and ribavirin (PR) compared to the control arm in which patients received a 4-week lead-in of PR followed by the addition of VICTRELIS (boceprevir) 200 mg Capsules."
Posted wrong link.
Thanks for catching it.
This is the study that would be of interest and I wish them success.
