Clinical Trials

Together, We Can Drive Toward a Cure


As the PFF Patient Registry advances our goal to learn more about pulmonary fibrosis from the patients that have volunteered to participate in the registry, moving forward clinical trials will use that data to find a cure for pulmonary fibrosis (PF). This is the first step  to increase our knowledge of the diseases that impact the lives of so many.

The Research community is aggressively investigating new treatments for all forms of pulmonary fibrosis. Our goal has been and will always be to prevent and cure the disease but in the short-term, researchers are working to control the disease progression and symptoms that patients experience.

As the Pulmonary Fibrosis Foundation is moving the field of research forward, this is an important first step of continuing our PFF 2020 strategic plan and creating the PFF Therapeutics Network. The therapeutics network’s goal is to support drug development to discover and advance new therapies to treat and cure disease via clinical trials.

But why? Clinical Trials are the final step to determine if an experimental treatment is safe and effective to treat a specific medical condition. Quite simply, clinical trials are not possible without you, the patient. 

The PFF Clinical Trial Finder is intended to help raise awareness of and increase participation in clinical trials, thereby accelerating the development of new treatment options for patients. Often, the most difficult step in the clinical trial process is finding people to participate. By making it easier and faster for patients to access information, the PFF expects to improve patient enrollment in clinical trials, which provide data for a better understanding of the complexity of the disease and its variable course.

The PFF Clinical Trial Finder and the PF Health app are the first steps toward creating the PFF Therapeutics Network and improving the lives of those impacted by pulmonary fibrosis.


about clinical trials

Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans. These studies also may show which medical approaches work best for certain illnesses or groups of people. Clinical trials produce the best data available for health care decision making.

The purpose of clinical trials is research, so the studies follow strict scientific standards. These standards protect patients and help produce reliable study results.

What is research?

Scientific research is the method of pursuing knowledge about nature. Clinical research focuses on patients with a disease.

                                     Observational vs interventional

When we compare the effect of treatments against a control in human beings, we call it a clinical trial.


Types of Clinical Trials: There are three (3) different types of clinical trials: interventional, observational, and expanded access.

  1. Interventional studies are those in which the research subjects are assigned by the investigator to a treatment or other intervention, and their outcomes are measured.

  2. Observational studies are those in which individuals are observed (no intervention in the study) and their outcomes are measured by the investigators.

  3. Expanded access studies are those in which the Food and Drug Administration (FDA) allows manufacturers to provide investigational new drugs (under certain circumstances), to patients with serious diseases or conditions who cannot participate in a clinical trial.


Basic science studies are done to increase the fundamental understanding of the disease process on a molecular and cellular level. In the long term, this type of research can provide the scientific basis for the development of effective treatments.

Epidemiological research studies a disease within certain populations; research in this area can lead to better understanding of potential risk factors, including occupational or environmental exposures that may lead to development of a disease.

Translational research translates basic research findings into meaningful treatments and clinical applications. This research is becoming increasingly prominent and the National Institute of Health is proposing the creation of a National Center for Advancing Translational Sciences (NCATS).

Clinical Research studies are performed to determine the safety and efficacy of medications, treatment regiments, and diagnostic procedures. The different phases of clinical trials for the development of new therapies are described below.

Quality of Life/Social Science studies are a subcategory of Clinical Research, which had been previously often ignored but has gained increased attention by the research community and the regulatory agencies. The term is used to refer to the general “well-being” of individuals undergoing specific treatment modalities, not only including medications but also supportive therapies (nutrition, exercise, respiratory therapy and psycho-social support).

With studies currently in various stages of development, there are a variety of clinical trials that are actively seeking the participation of patients. Some of the therapeutic approaches currently being studied include:

  • Anti-fibrotic therapies, which may slow or inhibit the production of scar tissue (fibrosis).

  • Inhibitors of “growth factor” proteins, which block proteins that stimulate the lungs to make scar tissue

  • Stem cell therapies, which may help damaged lungs to heal

  • Genetic research to identify genes and genetic variants that may be associated with the development and progression of PF
Clinical trials investigate dosage, safety, efficacy and potential outcomes of drugs or treatments in disease-specific populations through controlled trials. There are typically three stages or phases of clinical trials that must be performed before a drug or treatment may be submitted to regulatory agencies (ie: U.S. Food & Drug Administration) for approval. Prior to commencing a clinical trial, a drug must have demonstrated safety and efficacy in a laboratory model.

  1. Phase I: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.

  2. Phase II: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.

  3. Phase III: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments (or placebo), and collect information that will allow the drug or treatment to be used safely.

  4. Phase IV: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
