RegisterPilot or pivotal ? [General Statistics]
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.

R's base package has 274 reserved words and operators, along with 1761 functions. I can use 18 of them (about 14 of them properly). I believe this makes me the Donald Trump of programming.
