A Study to Establish Safety and Maximum Tolerated Dose of IV Trehalose in Healthy Subjects

November 21, 2016 updated by: Bioblast Pharma Ltd.

A Single Center, Single Ascending Dose, Double-Blind, Randomized, Placebo-Controlled Trial to Establish Safety and the Maximum Tolerated Dose of Intravenous Trehalose Solution in Healthy Subjects

This will be a double-blind, randomized, placebo-controlled, single ascending dose study performed in healthy subjects.

The study will include up to four escalating dose cohorts with eight (8) subjects in each cohort.

In each cohort, eligible subjects will be randomized in a 3:1 ratio to receive single IV administration of 9% trehalose (Treatment Arm 1) or placebo (Treatment Arm 2).

All subjects, regardless of their treatment arm assignment, will undergo the same evaluations and will receive the study drug at the clinic. Each subject will continue to be followed for one week post dosing.

Detailed Description

This is a double-blind, randomized, placebo-controlled, single ascending dose study performed in healthy subjects.

The study will include up to four escalating dose cohorts with eight (8) subjects in each cohort.

In each cohort, eligible subjects will be randomized in a 3:1 ratio to receive single IV administration of 9% trehalose (Treatment Arm 1) or placebo (Treatment Arm 2).

All subjects, regardless of their treatment arm assignment, will undergo the same evaluations and will receive the study drug at the clinic. Each subject will continue to be followed for one week post dosing.

Cohorts 1 to 3 After all subjects in a given cohort complete their 1-week follow-up visit (Visit 4), a Safety Review Committee (SRC) will review the safety and PK data of that cohort. If no safety concerns are identified, and the exposure data supports a higher dose is acceptable, the SRC will approve continuation into the next cohort (dose level).

Cohort 4 Cohort 4 will be initiated based on review of the safety and exposure data from the first 3 cohorts by the SRC. This cohort will only be performed if there is a suggestion that exposure can be safely increased.

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.

Ages Eligible for Study

14 years to 51 years (Adult)

Accepts Healthy Volunteers

No

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
Safety and tolerability of escalating doses of intravenously administered trehalose (incidence of adverse events and serious adverse events, including clinically significant laboratory abnormalities)
Time Frame: Will be assessed during the entire study. At screening, at day -1 before drug administration, and day 1 of drug administration before, during and after drug administration, and at day 8 the follow up visit

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
Maximum-tolerated dose (MTD) of trehalose administered intravenously (Averse events, vitals signs)
