A number of ongoing or proposed research studies have been noted in the evaluation of burosumab. Burosumab has a conditional marketing authorisation for the treatment of X‑linked hypophosphataemia (XLH). The marketing authorisation is conditional on further data collection in 3 of the clinical studies considered in this evaluation: CL205; CL201; and CL301. Further to this, the company noted that it is developing a European registry and running disease-monitoring programmes in the United States and Japan to generate more data in young people aged 13 years and over. It also explained that there was a planned long-term real-world-data collection programme for burosumab.
