E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Fibrous Dysplasia of Bone, MedDRA 8.0, 10016664 |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Define the efficacy of a bisphosphonate, risedronate (associated with calcium and vitamin D supplementation, or to calcium, oral phosphate, and calcitriol supplementation) to reduce bone pain in patients with fibrous dysplasia of bone.
Define the effect of risedronate in the prevention of the evolution of osteolytic lesions in patients with fibrous dysplasia of bone. |
|
E.2.2 | Secondary objectives of the trial |
Define the safety and tolerability of the bisphosphonate risedronate (associated with calcium and vitamin D, and to oral phosphate in patients who have renal phosphate wasting) in patients with fibrous dysplasia of bone.
Examine the effect of risedronate to improve quality of life in patients with fibrous dysplasia of bone. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Study I: Patients with fibrous dysplasia with painful lesions of intensity above 3 on a visual scale analog from 0 to 10.
Study II: Patients with fibrous dysplasia of bone with at least one osteolytic lesion and no current bone pain. |
|
E.4 | Principal exclusion criteria |
patients yournger than 8 years patients with other diseases or receiving treatments likely to affect bone metabolism patients with significant upper gastrointestinal disorders renal insufficiency (creatinine clearance <25 ml/min) liver disease
in both studies estrogen replacement therapy will be allowed
women at child bearing age should have a negative pregnancy test and be willing to use a medically acceptable method of contraception |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Study I: Reduction in bone pain assessed by a visual analog scale; reduction of the number of painful bone sites, decrease in the use of analgesics. Improvement of the quality of life, reduction in biochemical markers of bone metabolism, radiological improvement and increase in bone mineral density.
Study II: Radiological improvement of lytic bone lesions, assessed quantitatively |
