I first saw it in the endocyte's Analyst day presentation 2-3 years back. Since then we didn't hear much until now.
You may Google and find the analyst day ppt
There is no time limit.
A patent app. prosecution typically 1-3 years, but can take several years (e.g. Enbrel patent was granted after 17 years from the date of filing!!)
So you never know.
Though one can keep track through public PAIR from USPTO website reg. status of patent application.
From my limited knowledge being a Formulation Scientist for last 6+ years, I expect the Cmax to be lowered and AUC either lowered/improved compared to oral solution. Anyways, they shall present it positively.
They didn't sell when Merck was probably interested to buy the whole company (in my opinion, Merck was interested in buying it whole before the partnership deal with ECYT).
A BO doesn't make sense as the buyer wouldn't have much visibility into the future of the ECYT pipeline, especially after PROCEED failure. For ECYT selling right now wouldn't yield the right value.
@stephata75 I can't get what u r saying....
