The Cystinosis Research Network is compiling a listing of individuals who are interested in participating in cystinosis research studies. If you are interested, please submit the form below. The researchers may then contact you directly in the future with various research opportunities.

Submitting this information in no way indicates your commitment to participate in any clinical trial. Rather, it simply gives your permission for researchers to contact you directly. By forwarding this information, you give CRN permission to release it to researchers and their staff.

"Every time we see our daughter laughing, we give thanks to doctors and those families that went through initiating clinical trials more 20 years ago to make it possible. Because of them, we can go to the pharmacy and get the medicine as part of our routine and then go on living our lives."

Studies currently recruiting volunteers

SLEEP, MEMORY & THINKING in Adults with Cystinosis

Dr. Doris Trauner and her research group at the UCSD School of Medicine are conducting a research study to evaluate the relationship between sleep, memory and thinking in adults with cystinosis. We are looking for adults with cystinosis to participate in an overnight sleep study and cognitive testing focusing on memory.

Participation involves completing questionnaires, performing tests of memory and thinking, and sleeping overnight in a UCSD sleep laboratory. The questionnaires and memory and thinking assessments will take about 5-6 hours to complete. The sleep study portion will require an overnight stay in a sleep lab with the placement of electrodes for recording bodily functions such as heart rate and muscle movements, but will be completely non-invasive and non-painful. The study will pay for travel and meals, and participants will receive the results of both their memory and thinking tests and sleep assessments. If any problem is found in the sleep study, we will send the results to your primary care physician.

For more information, please contact Jennifer Crowhurst at jcrowhurst@ucsd.edu or Tammy Vu at 858-822-6700.

Muscle Strength in Cystinosis

Dr. Larry Greenbaum from Emory University is conducting a study of muscle strength in patients with cystinosis. Loss of muscle strength is a common complication in adults with cystinosis. This study will measure grip strength (squeezing a grip for 5 seconds) in patients who are at least 6 years old. The goals of the study are to determine risk factors for decreased grip strength and to determine the severity of the problem in patients with cystinosis. Describing the problem will hopefully lead to studies of interventions to slow or reverse the loss of muscle strength. Grip strength may be a good way to monitor therapies. Dr. Greenbaum previously published a study in Journal of Pediatrics showing that decreased grip strength is common in pediatric kidney transplant recipients. Study participation will be available to patients at the CRN conference in Utah (July 13 – July 15) and to the large number of patients with cystinosis who are followed at Emory University. Study participation will take about 5-10 minutes.

Brain Processing and Integration of Sensory Information in Cystinosis

Albert Einstein College of Medicine Searching for Participants for Children with Cystinosis for Study on How the Brain Processes and Integrates Sensory Information.

The team from the Cognitive Neurophysiology Lab invite children with Cystinosis to take part in a study using EEG to observe the reaction of the child’s brain while he/she listens to sounds and views images.

Data will be collected at the 2017 CRN Family Conference at Snowbird Resort July 13th – July 15th, 2017. Those qualifying for the study will be compensated $15/hour. To learn more, contact Ana Alves Francisco at (718) 862-1824 orana.alvesfrancisco@einstein.yu.edu and check out their flyer.

CTNS Nonsense Mutation Screening

The McGill University Montreal Children’s Hospital invites cystinosis patients to join a study concerning a specific type of genetic alteration called a “Nonsense Mutation”. Although cystinosis is caused by many different disruptions of the CTNS gene, we are particularly interested in “nonsense mutations” which trick the cell into stopping production of cystinosin protein. Several pharmaceutical companies are working hard to develop medications related to a well-known antibiotic (gentamicin) that permits the cell to disregard nonsense mutations.

Nonsense Mutations are estimated to account for about 10-15% of cases in other genetic diseases, but the prevalence in cystinosis is unknown and there is some evidence that CTNS Nonsense Mutations are clustered in certain regions. Looking forward, cystinosis patients may wish to know whether or not they carry a nonsense mutation. We would like to survey the cystinosis community and characterize the prevalence and distribution of Nonsense Mutations among cystinosis patients in North America and Europe. This would simply involve (prepaid) mailing a sample of saliva to our research group at McGill University Children’s Hospital in Montreal. We would analyze the sequence of your CTNS gene and let you know for future reference whether or not you carry a nonsense mutation.
