Supporting research is an important part of the OI Foundation’s mission. Often, the success of clinical studies of a rare disorder like osteogenesis imperfecta (OI) depends on getting enough people to participate in the study so the results are meaningful. People who are interested in participating in a clinical trial are encouraged to review the fact sheet What You Need to Know about Clinical Studies. Additional information about research studies can be found on

Join the OI Registry
Individuals with OI (18 and older) and parents of children with OI are encouraged to join the OI Registry. The OI Registry is a database of individuals with OI who are interested in participating in OI research. Once you are enrolled, you will begin to receive information on upcoming studies and online surveys about OI. Your participation in these studies helps move OI research forward.
If you have any questions, please contact the OI Foundation at or (844)889-7579.

Participating in a Study

Understanding the Medical Research Process

There are different types of medical research:

  • A case study is a report of a single case: of how one doctor treated one patient.
  • An observational study is a report of the investigator’s observations about how a group of patients responded to a course of treatment. This kind of study can also be done to follow the natural history of a disorder like OI.
  • Clinical trials compare the ways different groups of patients respond to different courses of treatment. A controlled clinical trial compares patients receiving a treatment with patients receiving no treatment (controls). It assesses how much of an effect the treatment has.

For a detailed discussion of the medical research process see the OI Foundation fact sheet Medical Research Clinical Trials.

Locating Studies

  • The website is a searchable website with extensive information about clinical trials in general as well as links to the trials themselves.
  • The OI Foundation periodically provides information about studies that are looking for participants who have OI. The Foundation’s Medical Advisory Council reviews all studies before they are advertised.
  • The OI Registry announces studies that have been approved by its board to all eligible members and provides information about how to contact the investigator.

Points to Consider

  • OI is a rare condition and there is still a lot to learn about its causes, its symptoms across a lifetime, and best treatments.
  • Many people who participate in clinical trials experience a considerable sense of satisfaction in knowing that they are helping advance medical understanding and treatments for themselves and others.
  • If you are thinking about participating in a clinical study it is important to get answers to all of your questions. Here are some sample questions.
      • What is the purpose of the study?
      • Who is going to be in the study?
      • Why do researchers believe the experimental treatment being tested may be effective? Has it been tested before?
      • What kinds of tests and experimental treatments are involved?
      • How do the possible risks, side effects, and benefits in the study compare with my current treatment? How might this trial affect my daily life?
      • How long will the trial last?
    • Will hospitalization be required?
    • Who will pay for the experimental treatment?
    • Will I be reimbursed for other expenses?
    • What type of long-term follow-up care is part of this study?
    • How will I know that the experimental treatment is working?
    • Will results of the trials be provided to me?
    • Who will be in charge of my care?

The Linked Clinical Research Centers program (LCRC), established by the OI Foundation and the Children’s Brittle Bone Foundation started a major longitudinal or natural history study of OI. The Longitudinal Study of Osteogenesis Imperfecta has been extended and expanded through the Brittle Bone Disorders Consortium. The purpose of this study is to collect information about the experiences of people with all types of OI across the entire life-span. Five centers in the United States and one in Canada are enrolling children and adults into this study. People of all ages and all types of OI are needed. Participants in the original study are encouraged to re-enroll at the site they had been using or at one of the newly added sites. If you were in the first study and have not been contacted by the study coordinator, please call them or call the OI Foundation. Study participants will receive an annual physical and various diagnostic studies.

The purpose of this study is to identify questions about the quality of life for people with Osteogenesis Imperfecta (OI). Quality of life is defined as an individual’s opinion of the quality of his or her daily life and includes emotional, social, physical environment and health related dimensions. It is important to see if the standard questions asking about quality of life are appropriate for people with OI or if a new set of questions should be created for the OI community.

The purpose of this laboratory study is to develop a non-invasive test to determine OI subtype. The study investigators will collect urine samples and look at various OI biomarkers in urine. There will be a total of 25 people with OI and 5 people without OI in this study. People with OI who agree to be in the study will be asked to provide a urine sample at their yearly longitudinal study of OI study visit. People without OI (controls) will be asked to provide a one time urine sample

The purpose of this study is to see if fresolimumab is safe as a treatment for OI. We will check the safety of a single dose of fresolimumab in the 1ststage of the study. We will check the safety of multiple doses of fresolimumab in the 2nd stage of the study. The Researchers will look at the effect of the two doses of fresolimumab in Stage 1on indicators of bone change and see the dose that shows the greatest reduction in bone change indicators compared to no treatment. This dose will be chosen for the repeat dose studies. If there were no big changes between the bone change indicators with either dose, the 4 mg/kg dose will be chosen for the repeat dose study.

The osteogenesis imperfecta program at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) enrolls children with types III and IV OI. Under the direction of Dr. Joan Marini, this program has over 25 years’ experience providing comprehensive multidisciplinary evaluations and care for children with OI. Pediatric participants are offered follow-up into young adulthood. Four protocols are available.

Screening Protocol: Children are first admitted under this protocol for diagnostic and screening evaluations. Testing may include: skin biopsy, blood draw, X-rays or bone density scan (DEXA).

Natural History Protocol: Provides comprehensive evaluation and monitoring. Includes genetics, rehabilitation, physical therapy, developmental, bone and spine X-rays, bone density scans (DEXA), dental, hearing, pulmonary, cardiac and neurologic examination.

Growth Protocol: This protocol evaluates the effectiveness of growth hormone on improving growth and bone quality in children with OI. All children complete a year of pretreatment measurements and testing before beginning one year of growth hormone injections. After the first year of treatment, children who respond to growth hormone may continue treatment for additional years.

Participation in NIH studies is free of charge. To learn more contact Dr. Joan Marini. Phone Number: 301-496-0741; Email:
