Looking for the latest in hypophosphatemia research and news? We've got the links here, or you can sign up to receive the updates in a newsletter (once or twice a year) with the latest news and research citations: http://eepurl.com/bVz6O5

Recent news:

Phase 3 clinical trials (adults with XLH) have begun for KRN23, a recombinant human immunoglobulin G isotype 1 (IgG1) monoclonal antibody (mAb) that binds to and inhibits the activity of fibroblast growth factor 23 (FGF23). For more information (two separate trials): https://clinicaltrials.gov/ct2/show/NCT02526160?term=XLH&rank=1 or https://clinicaltrials.gov/ct2/show/NCT02537431?term=XLH&rank=2

A Phase 2 clinical trial has begun for adults with TIO, also for KRN23, a recombinant human immunoglobulin G isotype 1 (IgG1) monoclonal antibody (mAb) that binds to and inhibits the activity of fibroblast growth factor 23 (FGF23). https://clinicaltrials.gov/ct2/show/NCT02304367?term=TIO&rank=1

Phase 3 pediatric trials for the same treatment are expected later in 2016.
