I attach some info about testing and developing inhaled metformin for lung cancer, which could act in synergy with other lung cancer drugs. Dr. John Patton, the inventor of Exubera inhaled insulin, is a consultant. Might you have an interest?
I have applied for a patent on inhaled antidiabetics for lung cancer treatment and prevention. Inhaled carboplatin is already being used for non-small cell lung cancer. Please see attached
A proof of concept with inhaled metformin in nude mice with lung tumors could be done at Charles River for about $200K. Celgene has sunk $130 million into http://agios.com
to develop drugs that would do the same thing metformin does, but it could be many years and $billions before they even have a candidate, let alone something to sell.
