Effects of Bisphosphonates on OI-Related Hearing Loss
What this study is about
Osteogenesis Imperfecta-related hearing loss usually occurs in individuals with mild (type I) OI and is much earlier in onset than age-related hearing loss, with the majority of individuals experiencing some minor hearing loss in their 20s. Bisphosphonates have been successfully used to treat otosclerosis, a common cause of hearing loss similar to OI-related hearing loss.
View original scientific description
Osteogenesis Imperfecta-related hearing loss usually occurs in individuals with mild (type I) OI and is much earlier in onset than age-related hearing loss, with the majority of individuals experiencing some minor hearing loss in their 20s. Bisphosphonates have been successfully used to treat otosclerosis, a common cause of hearing loss similar to OI-related hearing loss. As many individuals with OI-related hearing loss also present with otosclerosis and because of their mechanistic similarities, the investigators propose studying the effects of bisphosphonate treatment on individuals diagnosed with both OI type I and hearing loss, thereby determining its effectiveness as a potential treatment for hearing loss. The investigators will enroll 50 individuals diagnosed with type I OI and age 18-100. 25 adults will be enrolled into the treatment arm and receive bisphosphonate treatment (must have at least mild hearing loss), while 25 adults will be enrolled into the control arm. The investigators will enroll 25 children (6-17 years of age) diagnosed with OI who are currently receiving bisphosphonate treatment as part of their care for orthopedic symptoms. The investigators will also observe 25 children (6-17 years of age) diagnosed with OI who are NOT currently receiving bisphosphonate treatment. The study duration is 63 months (approximately 5 years). Enrollment is anticipated to begin in November 2019.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
