Hi Ohlbe,

» Sure, when you only have one test formulation. But when you hesitate between two ? Would you directly go for a pivotal where both test formulations would be compared to the reference, and then file whichever one passes ?

This is purely hypothetical for me. As far as I recall, I have not ever faced such a situation where two test formulations targeting the same authority were heads-on compared in a pivotal trial. I have faced it numerous times in pilot trials, but here the choice of formulation rarely is based on the CI but just on the observed GMR.

If I were in a situation, hypothetically, where I had one pivotal trial with two passing T formulations against a single, and I only needed one approval, then I am not sure what I would base my choice on. It could be cost of goods, or a risk-based assessment of the manufacturing bottlenecks for the two T formulations. Not sure, I have a feeling this would not be science-driven but Guy-in-Armani-suit-driven.

Pass or fail!
