When I am reviewing literature on WD, I noticed that the drug Ammonium Tetrathiomolybdate is considered side effects-free, yet, it is not being prescribed. After investigation, I found out that this is an "orphan medicine" which means that no drug company is promoting it or doing trials to be accepted (FDA approved). Anybody knows what is going on? Is there a way to know whether this drug is truely effective and side-effects-free as indicated? I also read that it may be used to treat some forms of cancer too.
Any information (doctors who are familiar with this, pharmacies etc.) will be highly appreciated.
