About this study
Official title: Phase 1b Trial of Beloranib, a Novel Methionine Aminopeptidase 2 (MetAP-2) Inhibitor for Treatment of Extreme Obesity: Randomized, Double-Blind, Placebo-Controlled, Escalating Doses in Female Volunteers
The purpose of this study is to assess whether multiple doses of ZGN-433 are safe and effective.
Read the detailed description
This protocol is designed to test the safety and efficacy of a drug called Beloranib (ZGN-433). It is to be tested for its ability to reduce weight in obese female subjects who are of non-childbearing potential. The study will provide information on how much ZGN-433 gets into the blood, how long it stays in the body, and how it affects other biological markers.

What is being measured
The primary outcome is the main question the study is designed to answer.
Demonstrate safe doses of ZGN-433 for reduction of body weight in obese female volunteers.
Measures of the safety and tolerability of ZGN-433 include documentation of adverse events and changes (compared to baseline) in vital signs, physical examination, heart rhythm, and laboratory tests.
Measured: Approximately 4 weeks
Secondary outcomes (3)
Incidence, severity and dose-relationship of adverse events as well as changes in physical examinations, ECGs, vital signs and/or laboratory evaluations as a measure of safety and tolerability.
Measured: Approximately 4 weeks
Peak plasma concentration of ZGN-433 to assess relationship to weight loss.
Measured: Approximately 4 weeks
Elimination half-life of ZGN-433 to assess relationship to weight loss.
Measured: Approximately 4 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ZGN-433 and Normal Saline in people with Obesity, run by Zafgen, Inc. at 1 site in Australia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Dec 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Demonstrate safe doses of ZGN-433 for reduction of body weight in obese female volunteers. (time frame: Approximately 4 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Dec 2011.
