27. června 2017 aktualizováno: GlaxoSmithKline
A Randomized, Double Blind, Dose Escalation, Fusion, First Time in Human Study to Assess the Safety, Tolerability, Pharmacokinetics, and Antiviral Activity of Single and Repeat Doses of GSK2336805 in Healthy Volunteers and Single Doses in Chronically Infected Hepatitis C Subjects
This study is a three Part, Phase 1, randomized, dose-escalation, fusion, placebo-controlled, double-blind study to determine the safety, tolerability and Pharmacokinetic (PK) profile of GSK2336805 in healthy subjects and the safety, tolerability, PK, and antiviral profile of GSK2336805 in subjects chronically infected with HCV: i. Single doses in healthy subjects and the effect of food on GSK2336805 PK (Part 1).
ii. Repeat doses in healthy subjects (Part 2) iii.
Single doses in chronically infected HCV positive subjects (Part 3).

Popis
Inclusion Criteria:
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECG, including no cardiac, pulmonary, hepatic, biliary (except Gilbert's disease, gastrointestinal, or renal (defined as serum creatinine >1.5 mg/dL or a calculated creatinine clearance (CrCl)<50 mL/min), disorders, or cancer within the past 5 years (except localized or in situ cancer of the skin). A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. A single repeat laboratory evaluation is allowed for eligibility determination.
- Male or female between 18 and 65 years of age inclusive, at the time of signing the informed consent.
- A female is eligible to enter and participate in this study if she is of: Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation, bilateral oophorectomy, hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea.
- Male subjects must agree to use one of the contraception methods listed in the protocol.
- Body weight greater than or equal to 50 kg (110 lbs.) for men and greater than or equal to 45 kg (99 lbs.) for women. For Part 1, body mass index (BMI) between 18.5-32 kg/m2 inclusive will be allowed. For Part 3, BMI between 18.5-35.0 kg/m2 inclusive will be allowed.
- For healthy subjects in Part 1 and Part 2, Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), alkaline phosphatase, bilirubin, and creatinine less than the upper limits of normal (ULN) (isolated bilirubin <2.0xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- QTcB or QTcF < 450 msec; or QTc <480 msec in subjects with Bundle Branch Block.
- The subject's systolic blood pressure is inside the range of 90-140 mmHg, or diastolic blood pressure is inside the range of 45-90 mmHg or heart rate is inside the range of 50-100 beats per minute (bpm) for female subjects or 45-100 bpm for male subjects.
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- The subject is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions and is likely to complete the study as planned.
- The following are Supplemental inclusion criteria for Part 3: HCV positive subjects: Treatment naive chronically infected genotype 1 HCV patients, defined as infection for >6 months and no prior HCV therapy.
- An HCV RNA viral load of greater than 100,000 IU/mL using a COBAS TaqMan HCV test and HCV genotype 1a or 1b as assessed by VERSANT HCV genotyping LiPA 2.0 (Bayer Healthcare, Berkeley, California), or by direct Deoxyribonucleic acid (DNA) sequencing of the NS5B gene Hepatitis C virus infection of mixed genotype excluded. HCV subjects with mixed genotypes are not eligible for the study.

Each episode of ischemia must be separated by a minimum duration of at least 1 minute, during which the ST segment returns back to baseline (1x1x1 rule)
