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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Description of intervention(s) / exposure
This study will be a single-centre, double-blind, placebo-controlled, dose-escalation study to assess the safety, tolerability and PK of GMA301 (thereafter referred to as getagozumab), in healthy subjects. Four sequential dosing cohorts, each with 6 subjects receiving getagozumab and 2 subjects receiving placebo (total of 32 subjects), will be given increasing intravenous infusion,single doses of getagozumab. The doses administered will be 75, 200, 500, and 1000 mg, or matching placebo at Day 1 and monitor the adherence to the intervention by direct observation.
As a conservative measure for the safety of healthy human subjects in this Phase 1 study of getagozumab, sentinel dosing is proposed for each group. Two sentinel subjects (1:1 active to placebo) will be dosed first and the remaining 6 subjects in the cohort will be dosed 7 days later, followed by at least 12 days prior to the next cohort dosing. Before proceeding to the next cohort, the Safety Review Committee (SRC; including an independent SRC member or SRC members) will have to review all the clinical data of the just finished cohort and approve the dosing of the next cohort.
After Screening (Screening Period of 28 days), eligible subjects who meet the inclusion criteria and none of the exclusion criteria will be randomized into the study. A computer generated randomization schedule will be used. The treatment period will last up to 8 weeks, followed by a 2 week follow-up period. Blood sampling for PK will be performed at: predose, 4 hours (h), 8h, 24h, 72h, 168h (Day 7), Day 14, Day 21, Day 28, Day 42, Day 56 (Week 8), and Week 10. At each time point, 3 mL of whole blood will be collected for PK analyses.

Control group
Placebo

Outcomes
Primary outcome [1] 304293 0
Adverse events (AEs) will be assessed by laboratory parameters, vital signs, physical examination, ECG, routine clinical observations.
Timepoint [1] 304293 0
Baseline through 10 weeks, daily.
Primary outcome [2] 304455 0
The immunogenicity samples will be tested for the presence of ADAs. The results will be listed and summarized by treatment of serum assays for frequency of occurrence. Moreover, to evaluate the development of immunogenicity, shift tables will be used to compare the results obtained at Baseline with the results at Weeks 2, 4, and 10.
The details of the immunogenicity analysis will be outlined in greater detail in the SAP.
Timepoint [2] 304455 0
Baseline (Day 1), and at week2, 4, 10 (primary timepoint) after intervention commencement.
Secondary outcome [1] 342014 0
Assess the PK profile including AUC0-t, AUC0-inf, Cmax, Tmax, t1/2.
Timepoint [1] 342014 0
Predose, 4h, 8h, 24h, 72h, 168h (Day 7), Day 14, Day 21, Day 28, Day 42, Day 56 (Week 8), and Week 10.
