Any doctor can use any approved drug off label if

Any doctor can use any approved drug off label if he or she thinks it is worth trying. But pharmaceutical companies are not allowed to promote a drug for off label use. They’ll get fined hard if they do. Doesn’t mean it doesn’t happen. Neurontin for pain is one example from my pharma days. Pfizer paid around a billion dollars in fines for that one. That’s here though. If Qilu gets rights and gets it approved in China, maybe the industry is a little more lax about that kind of stuff there. In conclusion, I wouldn’t count on off label use for revenue generation.
