Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* No clinically relevant abnormalities in the results of laboratory evaluation at Screening
* Must test negative for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) at Screening
* Normal electrocardiogram (ECG) at Screening
* Normal blood pressure (BP) and heart rate (HR) in the absence of any medications for body weight between 50 and 125 kg and within ± 15% of ideal body weight or body mass index (BMI) between 18 and 28 kg/m2 at Screening
* Able to communicate well with the investigator and to comply with the requirements of the entire study
* Provision of written informed consent to participate as shown by a signature on the volunteer consent form
* Nonsmokers of at least 180 days (6 months) duration (< 10 pack/year history) prior to Screening
* Negative for drugs of abuse (including alcohol) at Screening and Day -5

* Normal intraocular pressure (IOP) between 10 and 21 mm Hg at Screening
* Male subjects who are sexually active must be willing to use effective barrier contraception (e.g., condoms) during heterosexual intercourse from Day -5 through completion of the study and continuing for at least 90 days from date of last dose of study drug
* Male subjects must refrain from sperm donation from Day -5 through completion of the study and continuing for at least 90 days from the date of last dose of study drug
* Non-lactating females. Females on hormone replacement therapy (estrogen/progesterone) or contraceptive therapy must be stabilized on a product and dose for at least 90 days prior to Screening
* Females must have a negative serum gonadotropin pregnancy test at Screening and Day -1
* Nonpregnant females of childbearing potential must agree to use highly effective (<1% failure rate) contraception during heterosexual intercourse from Screening, throughout the study, and for at least 30 days following the last dose of study drug

Can healthy volunteers participate?
Yes
Key exclusion criteria
* Any prior exposure to GS-9411
* Administration of any investigational drug in the period 84 days (12 weeks) prior to Screening; 112 days (16 weeks) if the previous investigational drug was a new chemical entity
* A need for any medication during the period 0 to 5 days prior to Screening, except those deemed by the principal investigator/clinical investigator not to interfere with the outcome of the study
* Existence of any surgical or medical condition which, in the judgment of the clinical investigator, might interfere with the absorption, distribution, metabolism, or excretion of the drug
