Brief summary
A Safety Study to Evaluate the Safety, Tolerability, and Pharmacokinetics in HCV Genotype 1 Infected Patients
Detailed description
A Phase 1, Randomized, Double-Blind, Placebo-Controlled Study in Healthy East Asian and Caucasian Volunteers to Evaluate the Safety, Tolerability, and Pharmacokinetics Profiles of Single and Multiple Ascending Oral Doses of TG-2349, and Followed by a Dose-Ranging Study in Hepatitis C Genotype 1 Infected Patients.
Interventions
DRUGTG-2349
Supplied as oral liquid formulation in pre-filled glass syringe. Two dose strengths, 25 mg TG-2349 (25 mg/mL in PEG 400, 1.1 mL fill) and 200 mg TG-2349 (50 mg/mL in PEG 400, 4.1 mL fill), are filled into 5-mL type 1 glass syringes. Required doses during clinical study are to be dispensed using the combination of the two dose units. The entire content of the syringe is to be taken by mouth.
DRUGplacebo
Available in two different unit doses, 1.1 mL and 4.1 mL PEG 400 in 5-mL type 1 glass syringes. They are identical in appearance and similar in weight to TG-2349 oral liquid syringes.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Antiviral activity of multiple ascending oral doses of TG-2349 in genotype 1, 2, 3, 4, 5, and 6 HCV-infected patients. | predose, and 1,2,3,4,6,8,12,24,36,48,72,96 hours post-dose | Descriptive statistics and graphs will be presented for the antiviral variables. Change from pre dose will be analyzed descriptively for each time point after study drug administration. Graphic displays of raw data and changes over time will be performed at each dosing level (plots of raw data of TG-2349 at each time point with mean and median). The breakthrough is defined as a greater than or equal to 1 log10 increase in HCV RNA above nadir, or detectable HCV RNA, while on treatment, after an initial drop to a level of below the detection. The slope of the plasma viral RNA decrease during the first few days of treatment, any subsequent plasma viral RNA increase observed during and/or after dosing, and all breakthrough events should be recorded and summarized. |
| Pharmacokinetics (PK) profiles of single and multiple ascending oral doses of TG-2349 in healthy East Asian and Caucasian volunteers. | predose, and 1,2,3,4,6,8,12,24,36,48,72,96 hours post-dose | Dose proportionality will be assessed by evaluating PK parameters AUC0-t, AUC0-inf, and Cmax. Parameters that are not dose dependent will be assessed by evaluating Tmax, t1/2, and λz. The linear relationship between the log-transformed PK parameter and the natural log of the dose will be tested using a linear lack-of-fit test. The dose-dependent parameters will not be dose normalized. Residual analysis will be used to assess the assumptions of normality and variance homogeneity for the statistical model. |

Special attention will be paid to Grade III or IV toxicities in all treatment levels. |
