About this study
Official title: A PHASE 3, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED STUDY TO ASSESS THE EFFICACY AND SAFETY OF ONCE-MONTHLY BEROBENATIDE IN ADULTS WITH OBESITY DISEASE IN JAPAN (VESPER-JM)
The purpose of this clinical study is to learn about safety and effects of berobenatide (PF-08653944) in adults with obesity disease, a condition in which a person has too much body fat, which can harm their health and increase the risk of other medical problems. Some participants in this study may also have type 2 diabetes, a condition in which the body does not use insulin properly, causing blood sugar levels to become too high.
This study is seeking participants in Japan who:
Read more
- Have obesity disease.
- May have type 2 diabetes.
- Meet the study-specific age, weight, and health requirements.
About 197 adults will take part in this study. Participants will be randomly assigned to receive either berobenatide or a placebo. A placebo looks like the study medicine but does not contain any active medicine.
Berobenatide or placebo will be given as an injection under the skin of the abdomen (belly area). The study will compare the experiences of people receiving berobenatide with those receiving placebo to determine whether berobenatide can help people lose weight. The study will also assess the safety of berobenatide and its effects on body weight and other health measures.
People will take part in this study for about 21 months. During this time, they will have about 16 study visits at the site. They will also have 2 study visits over the phone.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Berobenatide in people with Obesity, run by Pfizer at 36 sites in Japan.
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 2 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: looking for participants now, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 36 sites in Japan. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Pfizer CT.gov Call Center (1-800-718-1021, ClinicalTrials.gov_Inquiries@pfizer.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percent change from baseline in body weight (time frame: Baseline, Week 72). 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 6 Nov 2026.
