What is the FDA guidance on prior approval supplements?

Prior Approval Supplement (PAS) - Changes that have a substantial potential to have an adverse effect on product quality (i.e., major changes) require an applicant to report the change to the FDA in a supplement to the approved BLA.

What is the 75/75 rule in bioequivalence?

Historically, the 75/75 rule specified that the ratio of test-to-reference formulation of a bioavail- ability measure, such as area under the plasma concentration curve (AUC) or maximum plasma concentration (C,,,), arising in a bioequivalence study, must be at least 75 per cent of unity in at least 75 per cent of

What is the bioequivalence range for the Cmax ratio?

For two drugs to be bioequivalent, the 90% confidence intervals (90% CI) for the ratio of the means of Cmax and AUC must lie within the range 0.8 – 1.25.

What is the 80/125 rule for bioequivalence?

Average bioequivalence (ABE) is claimed if the geometric means ratio (GMR) of average bioavailabilities between test and reference products is within the bioequivalence limit of (80%, 125%) with 90% assurance based on log-transformed data.

What are the criteria for bioequivalence studies?

Products are considered to be bioequivalent, if the 90% confidence interval of difference in the average values of logarithmic parameters to be assessed between test and reference products is within the acceptable range of log(0.80) - log(1.25).

How close does a generic have to be?

The AUC of a generic formulation must be no less than 80% or no more than 125% of the brand name formulation. There is international consensus that differences within this range are not clinically significant. More importantly, the 90% confidence interval of the AUC must also fall within 80% to 125%.

What is the bioequivalence rule?

Two products are considered to be bioequivalent when they are equal in the rate and extent to which the active pharmaceutical ingredient (API) becomes available at the site(s) of drug action.
