Safety Study of VBY-036 in Healthy Volunteers After 7 Days of Oral Dosing (VBY036P1B)

December 27, 2013 updated by: Virobay Inc.

A Double-Blind, Randomized, Placebo-Controlled, Sequential, Multiple Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Oral Doses of VBY-036 in Healthy Subjects

VBY-036 may treat or prevent nerve pain. This study aims to find the highest safe and tolerable dose of VBY-036 in healthy volunteers. Volunteers will be randomly selected to receive either a placebo or VBY-036 (30, 100, 300, 600 or 900 mg) once daily for seven days in a row.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Highest safe and tolerated VBY-036 dose
Time Frame: 7 days of dosing

Single dose of VBY-036 given daily for 7-days in a row for each cohort in an ascending manner.

Cohort B1 with 30 mg dose or placebo; Cohort B2 with 100 mg dose or placebo; Cohort B3 with 300 mg dose or placebo; Cohort B4 with 600 mg dose or placebo; Cohort B5 with 900 mg dose or placebo
7 days of dosing

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Confirmation of cathepsin-S inhibition
Time Frame: 7 days
Based on the accumulation of Iip 10 and/or cathepsin S protein levels
7 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
