Scleroderma Program clinical researchers and study coordinators are continuously conducting clinical trials and observational studies, along with maintaining numerous registries, in a variety of areas to better understand scleroderma and to find effective treatments for the disease and its complications.
Clinical Trials
Clinical trials are research studies that evaluate an intervention, whether it be a drug, device, or procedure. For our scleroderma-related clinical trials, we primarily study drugs to see if they may be beneficial in relieving symptoms associated with scleroderma. Many of the drugs we study are approved by the FDA to treat other conditions not related to scleroderma, but have not yet been evaluated for use in treating scleroderma-associated symptoms. Please see below for a list of our current clinical trials.
Observational Studies & Clinical Registries
Observational studies are done to observe a patient’s disease, symptoms, and health over time without introducing an intervention, such as a medication. For clinical registries, data (such as biological, clinical, and self-report) are collected at points over time to evaluate specified outcomes for people with a specific disease or condition. These studies provide us with more knowledge about rheumatologic conditions, like scleroderma, and how we may be able to better diagnosis and treat patients in the future. Please see below for a list of our current observational studies and clinical registries.
Sign Up to Be Contacted About Upcoming Studies
If you are interested in being contacted about upcoming studies, please see below for the Sclero-Rehab Research Recruitment Registry. The purpose of this registry is to inform you about future research opportunities in the UM Scleroderma Program. These study opportunities may be focus groups, behavioral studies, clinical studies, or intervention research. By providing some basic information, we can target our advertisements to specific research opportunities that you might qualify for.
Study Coordinators

Rosemary Gedert completed her Bachelor’s Degree in Biomolecular Science in 2021 at the University of Michigan, then completed her Master’s Degree in Biochemistry at the University of Michigan Medical School in 2022. Rosemary began working at Michigan Medicine shortly after in May 2022. She is the main study coordinator for many of the observational studies focused on scleroderma and rheumatoid arthritis at Michigan Medicine.

Ryan Lee graduated from the University of Michigan in 2019 with a Bachelor of Science in Chemical Engineering. Ryan later completed a career changing pre-med postbacc at Case Western Reserve University in 2021. He joined Michigan Medicine at the beginning of 2022 and works closely with Dr. Dinesh Khanna and Dr. David Roofeh on their scleroderma research. Ryan is the main study coordinator for several ongoing clinical trials within the Scleroderma Program, ranging from a NIH-funded COVID-19 booster vaccine study to industry-funded drug studies aiming to treat scleroderma.
Current Clinical Trials
PROMIS Integration Trial
The purpose of this study is to evaluate the effects of Patient-Reported Outcome (PRO) implementation on the processes of care, clinical decision making, patient-provider communication, and health comes.
Learn More
We are looking to identify barriers and facilitators to PRO implementation from the perspectives of patients and HCPs to develop and refine approaches to training and supporting HCPs to use PROs effectively as tools for chronic disease management. In doing so, we hope to find ways to improve the use of PROs, health outcomes, patient-provider communication, medical decision making, and patient satisfaction.

ArthritisPower Trial: Impact of a Mobile Health Application on Rheumatoid Arthritis
The goal of this study is to improve disease outcomes and health related quality of life for patients with rheumatoid arthritis (RA) by improving shared decision-making about treatment options.
Learn More
We believe that having patients collect data on their symptoms and health status between clinic appointments and providing this information to them and their rheumatology health care providers will improve the quality of the patient-provider interaction. However, this is not currently the standard of care. We anticipate this will improve shared decision-making and lead to better disease control and enhance health-related quality of life.
Recruitment status
- Currently recruiting
Who can participate?
- Adults 18 years or older with a diagnosis of rheumatoid arthritis (RA) who’s provider is participating in the study.
What is involved?
- Depending on your health care provider, you may be placed into one of two study groups. One group will use the Arthritis PowerTM app for the first year of the study and the other will not.
- After the first year of the study, all participants, no matter their study group, will be encouraged to use the Arthritis PowerTM app for up to two years.
- Participants will be asked to complete surveys at some of their regularly scheduled standard of care appointments.
- We will collect clinical information from your standard of care appointments and procedures.
