Weight loss is harder for some people than it is for others.  For people who have not met weight loss goals through dieting, our clinical study may be an option.

Obesity is a serious health condition characterized by excess weight or body fat that may affect an individual’s health and, in some cases, can affect people both physically and psychologically.  See if you may qualify for a clinical trial of an oral study drug for weight loss.

The age a person must be to participate in a clinical trial.


Male or Female

The sex of people who may participate in a clinical trial. Sex is a person’s classification based on assignment at birth. Eligibility based on sex is distinct from eligibility based on gender.

Each clinical study has its own guidelines for who can participate, called eligibility criteria. However, only the research study staff can determine if you qualify to enroll in the study.

Get started — See if you may qualify

A first step as you consider this study is to answer a 5-minute questionnaire about your health and medical history. If your answers show the study might be a good fit for you, you maychoose to be referred to a study clinic that you select.

You will then be asked to provide your contact information for a study representative to contact you and discuss the next steps. If you’re interested, they will do a more detailed review of your medical history to see if you are able to participate. Only the study staff can determine if you meet the study’s eligibility criteria and are able to enroll in the study.

Your answers to these initial questions will only be linked to you if your responses indicate that you may be eligible to participate in this study and you choose to share your contact information with the study team. Pfizer study team members and our partners will have access to reports containing aggregated data that will not be directly linked back to you.
