Descriptive Information
Brief Title  ICMJE Safety of Fresolimumab in the Treatment of Osteogenesis Imperfecta
Official Title  ICMJE Multicenter Study to Evaluate Safety of Fresolimumab in Adults With Moderate-to-severe Osteogenesis Imperfecta
Brief Summary

Osteogenesis Imperfecta (OI) is a rare disorder that causes bones to break easily. People with OI may have broken bones with little or no trauma, dentinogenesis imperfecta (DI), and, in adult years, hearing loss. OI can range from very severe to very mild. The current standard-of-care for severe types of OI involves the use of IV medications (bisphosphonates) and surgery to put rods in bones to strengthen them. These therapies, although often life-saving, are new and very little is known about their long-term effects on bone and other body systems.

Transforming growth factor beta (TGF-β) is a protein important in bone formation. Fresolimumab is an antibody that can silence TGF-β . In studies with mice with OI, it has been shown that silencing TGF-β can lead to higher bone mass, quality and strength. The purpose of this study is to determine if fresolimumab is safe in the treatment of OI.

Detailed Description

Osteogenesis Imperfecta (OI) is a rare disorder that causes bones to break easily. People with OI may have broken bones with little or no trauma, dentinogenesis imperfecta (DI), and, in adult years, hearing loss. It is seen in both genders and all races. OI can range from very severe to very mild. Individuals with the most severe type of OI may die at birth. People with severe OI who survive may have bowed arms and legs, very short stature and be unable to walk. People with the mildest form of OI may only break bones occasionally and have normal height and lifespan. Breaks can occur in any bone, but are most common in the arms and legs. The current standard-of-care for severe types of OI involves the use of IV medications (bisphosphonates) and surgery to put rods in bones to strengthen them. These therapies, although often life-saving, are new and very little is known about their long-term effects on bone and other body systems.

TGF-β is a protein important in bone formation. Studies have shown that increased TGF-β activity leads to lower bone mass and strength and increased fractures. Fresolimumab is an antibody that can silence TGF-β . In studies with mice with OI, it has been shown that silencing TGF-β can lead to higher bone mass, quality and strength.

Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE Osteogenesis Imperfecta
Intervention  ICMJE Drug: Fresolimumab
The purpose of this study is to determine if fresolimumab is safe as a treatment for OI. We will evaluate the safety of a single dose of fresolimumab in the 1st stage of the study. We will evaluate the safety of multiple doses of fresolimumab in the 2nd stage of the study. The Investigators will evaluate the effect of the two doses of fresolimumab in Stage 1 on markers of bone turnover and determine the dose that shows the greatest reduction in bone turnover markers compared to no treatment. This dose will be chosen for the repeat dose studies. If there were no significant changes between the bone turnover markers with either dose, the 4 mg/kg dose will be chosen for the repeat dose study.
Study Arms  ICMJE
  • Experimental: Stage 1 Low dose

    There are a total of 6 study visits within approximately a 6 month timespan. Investigators will evaluate the safety of a single administration of fresolimumab in adult patients with OI. Subjects will receive a single-dose of 1 mg/kg of fresolimumab (n=4).

    At each study visit, the participant may have the following testing done:

    • Physical exam
    • Vitals
    • Blood draw for safety labs, pharmacokinetics, etc

    Intervention: Drug: Fresolimumab
  • Experimental: Stage 2 High dose

    There are a total of 6 study visits within approximately a 6 month timespan. Investigators will evaluate the safety of a single administration of fresolimumab in adult patients with OI. Subjects will receive a single-dose of 4 mg/kg of fresolimumab (n=4).

    At each study visit, the participant may have the following testing done:

    Fresolimumab will be administered every six months for a total treatment period of 12 months (n=4). The dose to be administered (1 or 4 mg/kg) will be chosen after completion of Stage 1. The primary Stage 2 endpoint will be safety measures assessed over 12 months. The secondary endpoints will be changes in markers of bone remodeling, bone mineral density, estimated strength.

    At each study visit, participants may have the following testing done:

    • Physical exam

    Fresolimumab will be administered every three months for a total treatment period of 12 months (n=4). The dose to be administered (1 or 4 mg/kg) will be chosen after completion of Stage 1. The primary Stage 2 endpoint will be safety measures assessed over 12 months. The secondary endpoints will be changes in markers of bone remodeling, bone mineral density, estimated strength.
