NCT03003338

Brief Summary

This is a 1:1 randomized double-blind Placebo-controlled moncenter Phase IV study to investigate whether a successful interferon-free treatment of HCV-infection with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in combination with dasabuvir (DSV) improves the patients' attention ability as compared to placebo as measured with the Att Test Sum Score change from baseline to week 12. A total of 30 patients with non-cirrhotic genotype 1b HCV infection will be randomly assigned to receive 12 weeks verum followed by 12 weeks Placebo (arm A) versus 12 weeks Placebo followed by 12 weeks verum (arm B). Patients will be followed up for 48 weeks.

Outcome Measures

Primary Outcomes (1)

  • Change in the Attention Test Battery Sum Score (Att Test Sum Score) at week 12 (12 weeks minus baseline)

    To investigate whether a successful interferon-free treatment of HCV-infection with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in combination with dasabuvir (DSV) improves the patients' attention ability as compared to placebo as measured with the Att Test Sum Score change from baseline to week 12.

    12 weeks

Secondary Outcomes (30)

  • Efficacy of treatment with OBV/PTV/r in combination with DSV for 12w in patients with chronic genotype 1b HCV infection as measured by the proportion of subjects with sustained viral response at FU 12 after discontinuation of therapy

    Baseline and FU12

  • Efficacy of treatment with OBV/PTV/r in combination with DSV for 12w in patients with chronic genotype 1b HCV infection as measured by the proportion of subjects with sustained viral response at FU 24 after discontinuation of therapy

    Baseline and FU 24

  • Efficacy of treatment with OBV/PTV/r in combination with DSV for 12w in patients with chronic genotype 1b HCV infection as measured by the proportion of subjects with sustained viral response at FU48 after discontinuation of therapy

    Baseline and FU 48

  • Change in FIS at Treatment week 12 after Treatment discontinuation

    Baseline and week 12

  • Change in FIS at Treatment at 12 weeks of follow-up after Treatment discontinuation

    Baseline and 12 weeks of follow-up

  • +25 more secondary outcomes

Other Outcomes (5)

  • HCV-specific T cell responses

    Baseline and 48 weeks follow-up

  • HCV-specific T cell responses

    Baseline and 48 weeks follow-up

  • Relationship between NK cell phenotype and function

    Baseline and 48 weeks follow-up

  • +2 more other outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Willing and able to provide written informed consent
  • Male or female, age ≥18 years
  • Chronic hepatitis C virus infection
  • Fatigue Impact Scale Score (FIS) \>45 and a sum score (Att Test Sum Score) \>0.4 in the battery of attention tests applied.

  • practicing total abstinence from sexual intercourse (minimum 1 complete menstrual cycle)
  • sexually active with female partners only
  • not of childbearing potential, defined as:
  • postmenopausal for at least 2 years (defined as amenorrheic for longer than 2 years, age appropriate, and confirmed by a follicle-stimulating hormone \[FSH\] level indicating a postmenopausal state), or

(Note: Ethinylestradiol-containing hormonal contraceptives, including oral, injectable, implantable, patch and ring varieties, may not be used during study drug treatment.)
  • Females of childbearing potential must have negative results for pregnancy tests performed:
  • at Screening on a serum specimen obtained within 28 days prior to initial study drug administration, and

  • Clinically-significant illness (other than HCV) or any other major medical disorder that, in the opinion of the investigator, may interfere with subject treatment, assessment or compliance with the protocol; subjects currently under evaluation for a potentially clinically-significant illness (other than HCV) are also excluded.
  • Positive result of a urine drug screen at the Screening Visit for opiates, barbiturates, amphetamines, cocaine, benzodiazepines, phencyclidine, and propoxyphene.
  • History of uncontrolled seizures, cancer (except basal cell carcinoma of the skin), or uncontrolled diabetes, as defined by a hemoglobin A1C level \> 8.0% or other systemic diseases that affect directly the CNS and brain metabolites.

  • Chronic liver disease of a non-HCV etiology (e.g., hemochromatosis, autoimmune hepatitis, alcoholic liver disease, Wilson's disease, α1 antitrypsin deficiency, cholangitis)
  • Difficulty with blood collection and/or poor venous access for the purposes of phlebotomy.
  • Clinical hepatic decompensation (i.e., clinical ascites, encephalopathy or variceal hemorrhage).

  • Significant pulmonary disease or significant cardiac disease.
  • +15 more criteria
