Internal medicine includes many different conditions. Some of these, such as high blood pressure, high cholesterol, or diabetes, are familiar to most of us because we have one or more of them or know someone who does. These conditions can significantly harm an individual’s overall health if they are not treated effectively. Even though safe and effective treatments are already available for many of them, we continue to learn about new, different, and potentially better options.

Areas of focus for Pfizer’s clinical research in internal medicine include cardiovascular diseases, diabetes, infectious diseases, liver disorders, and obesity. We invite you to explore our clinical trials in internal medicine below.

Frequently asked questions

Why are there clinical trials for chronic conditions, such as cardiovascular diseases or diabetes, that already have treatment options?

Even though safe and effective treatments are already available for many of these conditions, we continue to learn about new, different, and potentially better ways of treating them.

The goal is to provide the best treatment options for every individual. For some people, the current treatments are not enough. We are seeking to develop new treatment options, either given alone or in combination with current treatment options, that we hope will improve outcomes for these individuals.

Why is Pfizer conducting clinical research related to obesity?

Obesity can have significant impact on a persons overall health.

We know that obesity increases peoples risk of high blood pressure, heart disease, diabetes, cancer, and other chronic conditions. We also know there are many reasons why it is difficult for people to manage their weight and avoid being obese.

Developing treatments for obesity may help those who struggle with their weight to potentially lower their risk of other health conditions.

What happens in a clinical trial?

What happens in a clinical trial depends on the protocol. A protocol is a detailed plan that explains the purpose of the clinical trial and how it will be run. If you consider joining a clinical trial, these details will be explained to you as part of the informed consent process. They include: 

  • the length of the clinical trial 
  • the study medicines, procedures, and tests in the clinical trial  
  • the schedule of study activities 
  • information about who can participate 
  • how side effects will be tracked, managed, and reported 
  • the rules that must be followed 

A clinical trial may also have aspects such as randomization, placebo, or blinding.

Who can join a clinical trial?

We encourage everybody to consider joining clinical trials. There are many types of clinical trials that study different aspects of health in people with a variety of backgrounds and conditions. Each clinical trial has its own criteria for who may participate. These are called eligibility criteria.  
 
Eligibility criteria include things like your age, sex, overall health, type of condition, and your medical treatment history. As part of the steps to join a clinical trial, the study doctor will confirm whether you meet all eligibility criteria and are able to participate.

Participation in a clinical trial is always voluntary. The decision to join is personal, and it is yours.
