I am not sure what's on management's minds. They did indicate wanting to be a manufacturer. And, we know US market is the main target for IPCI. naturally, it make sense to invest in manufacturing sites in the US. Transportation cost should not be looked at lightly if everything has to ship from Toronto.
Glucophage manufacturing and transportation/distribution cost can eat into the profit. Plus you mentioned IPCI probably can't produce the required quantity. It would make more sense for a well establish partner to produce and sell it in large quantities.
I am not sure about IPCI to distribute on their own. They would basically have to start a sales department to handle that.
Sales and advertisement is very costly, and I don't see IPCI can do something like that with their current financial situation. Plus Glucophage probably won't be able to generate enough revenue in the first few years to cover the cost involved in sales and advertisement.
A comparison with EGLT for example, they have a small sales force of under 100 people, and it takes them years to build that relationship with doctors and distributors. With ARYMO launch this month, they have 40 million in finance set aside just for ARYMO launch and advertisement cost for the next few years.
