Description
The primary objectives of this study are to evaluate the effect of KRN23 treatment on:
Increasing serum phosphorus levels in adults with TIO or ENS-associated osteomalacia
Improvement in TIO/ENS-associated osteomalacia as determined by osteoid thickness (O.Th), osteoid surface/bone surface (OS/BS), osteoid volume/bone volume (OV/BV) and mineralization lag time (MLt).
