I agree with CMO as 1.3 mL dose and 1.8 mL dose is considered to be a different strength, if its a unit dose injection. You need a separate specification for both individual strengths and need full study for each individual strengths.

We have a client who is has a 1.3 mL dose (mAb) in a 3 mL vial. They need to also have a 1.8 mL fill volume for clinical reasons - same 3 mL vial, same stopper, same formulation, absolutely nothing changed but the fill volume. The CMO says they will need to do a whole new set of specifications. I disagree. Opinions?
