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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Study type
Interventional
Description of intervention(s) / exposure
This is a 2-part, Phase I, single-centre, randomised, double-blind, placebo-controlled, sequential cohort study of single and multiple ascending doses of ALMB-0166 or placebo administered by intravenous infusion to healthy adult participants. Participant population to be enrolled in SAD and MAD parts of the study will be mutually exclusive. Part 1 will be single ascending dose (SAD) which will involve at least 4 cohorts testing single incremental doses of 1 mg/Kg, 3 mg/Kg, 10 mg/Kg and 25 mg/Kg. Part 2 of the study will be a Multiple Ascending Dose (MAD) involving up to 4 dosing levels to be determined after review of Part 1 which will be administered intravenously on Days 1, 8, 15 and 21. Dose escalation will be determined by a Safety Review Committee (SRC) that will review all the safety data available from the previous cohort. In both parts, the SRC should make a recommendation as to whether the next dose should be escalated or reduced, or additional subjects should be dosed in a same dose level of a cohort.

Adherence to the protocol intervention for SAD and MAD parts of the study will be performed through direct observation by study personnel since the investigational product will be administered in the phase I unit.

Categorical variables will be summarized by the number and percent of subjects in each category. Continuous variables will be summarized as summary statistics. Analysis of all safety data will be performed on the Safety Population and will be presented by the treatment received. Regarding PK analysis the concentrations of ALMB-0166 will be summarized using descriptive statistics (arithmetic means, SDs, coefficients of variation, sample size, minimum, maximum, and geometric means).
