MHH-HCV-NPM-Neuropsychiatric Manifestations of HCV-infection During and After Treatment With OBV/PTV/r and DSV

Study Overview
=================
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.

Eligibility Criteria
-----------------
Inclusion Criteria: 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. Female who is: 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 surgically sterile (defined as bilateral tubal ligation, bilateral oophorectomy or hysterectomy), or has a vasectomized partner (s); of childbearing potential and sexually active with male partner(s): currently using an effective method of birth control at the time of screening and agree to practice highly effective methods of birth control while receiving study drugs and at least one effective method of birth control during the follow-up period (see section 4.3). (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 on a urine sample obtained on Study Day 1 (prior to dosing). Males who are not surgically sterile and who are sexually active with female partner(s) of childbearing potential must agree to practice an effective form of birth control (see section 4.3) throughout the course of the study, starting with Study Day 1 and for 30 days after stopping study drug. Subject must be able to comply with the dosing instructions for study drug administration and be able to complete the study schedule of assessments. Body Mass Index (BMI) is > 17 to < 40 kg/m2. BMI is calculated as weight measured in kg divided by the square of height measured in meters (m). Confirmation of chronic genotype 1b HCV infection documented by the following: Positive for anti-HCV antibody or HCV RNA at least 6 months before Screening, and positive for HCV RNA and anti-HCV antibody at the time of Screening Per local standard practice, documented results of: Index (APRI) ≤ 2 at Screening, or FibroScan® result of < 12 kPa at Screening or The absence of cirrhosis based on a liver biopsy within the last 36 months. HCV > RNA 1000 IU/ml at Screening Subject must be of generally good health as determined by the Investigator. Subject has not been treated with any investigational drug or device or any commercially available anti-HCV agents within 42 days of the Screening visit. Exclusion Criteria: Any previous exposure to HCV protease inhibitors, HCV NS5A inhibitors or HCV polymerase inhibitors History of severe, life threatening or other significant sensitivity to any drug. Pregnant or nursing female or male with pregnant female partner Recent (within 6-months prior to study drug administration) history of drug or alcohol abuse that could preclude adherence to the protocol. Infection with hepatitis B virus (HBV; defined as HBsAg-positive) or human immunodeficiency virus (HIV) Use of any medication that are contraindicated for use with OBV/PTV/r and DSV within 2 weeks prior to study drug administration or 10 half-lives of the medication whichever is longer (see SmPC of OBV/PTV/r and DSV and section 4.4). 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. Gastrointestinal disorder or post operative condition that could interfere with the absorption of the study drug (for example, gastric bypass or severe ulcerative colitis). 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). Solid organ transplantation. Significant pulmonary disease or significant cardiac disease. Significant drug allergy (such as anaphylaxis or hepatotoxicity). Contraindications for MRI study Screening laboratory analyses show any of the following abnormal laboratory results: Alanine aminotransferase (ALT) > 10 × upper limit of normal (ULN) Aspartate aminotransferase (AST) > 10 × ULN Calculated creatinine clearance (using CKD-EPI equal) < 30 mL/min Albumin < lower limit of normal (LLN) INR > 1.5 Hemoglobin < LLN Platelets < 90,000 cells per mm3 Total bilirubin > 2.0 mg/dL HCV RNA levels that are above the upper level of assay quantification Screening ECG with clinically significant abnormalities Consideration by the Investigator, for any reason, that the subject is an unsuitable candidate to receive the study medication Donation or loss of more than 400 ml blood within 2 months prior to Baseline/Day 1
