This drug was developed specifically to target the effects of the FGFR3 mutation that causes the fibroblast growth factor receptor 3 to be overly active in people with achondroplasia, which prevents normal bone growth. The FDA cited this trial as the reason for the approval: a year-long, double-blind randomized trial (RTC) that showed an increase in growth (a mean of 1.57cm per year) in participants who received the drug. While some suggest that other health complications may be ameliorated by the use of vosoritide, that is purely speculation at this point. The FDA approval was based on the trial’s primary endpoint, “change from baseline of annualized growth velocity.”
While a spokesperson from the FDA proclaims that this approval “fulfills an unmet medical need for more than 10,000 children in the United States”, this drug is controversial among people living with achondroplasia and other types of dwarfism. Many believe that the approval of this drug based on the ability to only increase growth is centered on corporate interests to bring a high-cost commercial drug to market without evidence that health outcomes are improved and that this approval represents deep prejudice against people of short stature.
There is reasonable concern that the FDA’s enthusiastic support to celebrate the approval of this expensive drug to increase height can only further support discriminatory views that medical providers have had towards people with disabilities by validating that short stature in and of itself is a medical problem that needs a cure.
Daily injection of this drug is not necessary to allow people with achondroplasia to drive a car, reach the items they need, or take care of their own hygiene. Of course people with achondroplasia perform these activities all the time with assistive devices and inclusive design. This statement from BioMarin’s CEO may represent ignorance about the capabilities of someone with achondroplasia or, perhaps more likely, may be a misrepresentation to hype the importance of vosoritide.
