Safety and Efficacy of Grazoprevir (MK-5172) + Elbasvir (MK-8742) in Participants With Chronic Hepatitis C and Chronic Kidney Disease (MK-5172-052) (C-SURFER)

23 août 2018 mis à jour par: Merck Sharp & Dohme LLC

A Phase II/III Randomized Clinical Trial to Study the Efficacy and Safety of the Combination Regimen of MK-5172 and MK-8742 in Subjects With Chronic Hepatitis C Virus Infection and Chronic Kidney Disease

This study will evaluate the safety and efficacy of combination treatment with grazoprevir (MK-5172) + elbasvir (MK-8742) for cirrhotic and non-cirrhotic participants with chronic Genotype 1 (GT1) hepatitis C virus (HCV) infection and chronic kidney disease (CKD). The primary study hypothesis is that the proportion of HCV GT1-infected CKD participants within the Immediate Treatment and Intensive Pharmacokinetics (PK) groups achieving a sustained viral response 12 weeks after the end of all study treatment (SVR12) will be >45%.

  • Evidence or no evidence of liver cirrhosis based on one of the following:
  • Liver biopsy performed within 24 months of Day 1 (if participant is cirrhotic then there is no time restriction on biopsy)

  • Intolerant to prior interferon or pegylated intereferon with or without ribavarin regimen
  • Chronic kidney disease (defined as glomerular filtration rate [eGFR] <=29) non-dialysis dependent or on hemodialysis for at least 3 months, including individuals awaiting kidney transplant and those with failed kidney transplants but no longer on immunosuppressant therapy)
  • Female participant of reproductive potential must agree to remain abstinent or use (or have their partner use) 2 acceptable methods of contraception from at least 2 weeks prior to Day 1 through 14 days after the last dose of study drugs, or longer if dictated by local regulations

Exclusion Criteria:

  • Evidence of decompensated liver disease
  • On peritoneal dialysis for management of kidney disease
  • Co-infection with hepatitis B virus or human immunodeficiency virus (HIV)
  • History of malignancy <=5 years prior to signing informed consent
  • Clinical diagnosis of substance abuse
  • Pregnant, breast-feeding, expecting to conceive or donate eggs, or donate sperm from Day 1 through 14 days after the last study dose, or longer if dictated by local regulations
  • Organ transplant (including hematopoietic stem cell transplant) other than kidney, cornea, and hair
  • Conditions requiring, or likely to require, chronic systemic administration of corticosteroids during the course of the trial
  • Uncontrolled or poorly controlled hypertension
  • Significant cardiovascular disorder (e.g. myocardial infarction or unstable angina) or cardiovascular procedure within 3 months prior to signing informed consent
  • New or worsening signs or symptoms of congestive heart failure within 3 months of signing informed consent
  • Severe active peripheral vascular disease
  • Recent (within 3 months prior to signing informed consent) episode or recurrence of stroke, transient ischemic attack (TIA) or neurological disorder, including but not limited to seizures
  • Evidence or history of chronic hepatitis not caused by HCV

Principaux critères de jugement

Mesure des résultats
Description de la mesure
Délai
Percentage of Participants With Sustained Virologic Response 12 Weeks After Completing Study Therapy (SVR12)
Délai: Week 24 (Immediate Treatment + Intensive PK) or Week 40 (Deferred Treatment)
SVR12 was defined as hepatitis C virus (HCV) ribonucleic acid (RNA) lower than the limit of quantification (LLoQ) 12 weeks after completing study therapy. HCV RNA was measured using the COBAS™ AmpliPrep/COBAS™ Taqman™ HCV Test, v2.0®, which has a LLoQ of 15 IU/mL.
Week 24 (Immediate Treatment + Intensive PK) or Week 40 (Deferred Treatment)
Number of Participants Experiencing an Adverse Event (AE) During the Initial Treatment and 14-day Follow-up Periods
Délai: Up to Week 14
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. This analysis includes the Immediate Treatment + Intensive PK group and the placebo treatment period for the Deferred Treatment group.
Up to Week 14
Number of Participants Discontinuing Study Drug Due to AEs During the Initial Treatment Period
Délai: Up to Week 12
An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. This analysis includes the Immediate Treatment + Intensive PK group and the placebo treatment period for the Deferred Treatment group.
Up to Week 12
