As far as ethically questionable drugs go, particularly around genetic abnormalities, this one seems like it is about as uncontroversial as it can get. It doesn’t confer benefits to someone who doesn’t have the specific genetic issue. It works around the missing protein rather than trying to alter the broken gene. And there are significant co-morbidities that come along with dwarfism that make it more obviously a medical issue rather than just being about physical stature. It doesn’t change the underlying gene, so the issue can still be passed on to offspring. So nothing is being eradicated or erased. If it works as described it should be a highly effective treatment with minimal side effects which avoid a host of medical issues for the children that get it, besides giving them a good shot at > 1st percentile height. I can imagine much more ethically dubious treatments that will certainly be coming down the line as we continue to identify, target, and find ways to enhance these genetic pathways.
