 Biowaiver [Regulatives / Guidelines]

Dear Members,

We are planning to conduct BE study on Tenofovir (Class III) + Emtricitabine (class I) for a market which follows EU guidelines.

As per the EU guidelines "GUIDELINE ON THE INVESTIGATION OF BIOEQUIVALENCE"-Aug 2010, following is recommended

BCS-based biowaiver are applicable for immediate release FC products if all active substances in the FC belong to BCS-class I or III and the excipients fulfil the requirements outlined in section IV.2. Otherwise in vivo bioequivalence testing is required.

The guidelines specifes "all active substances in FC belong to BCS- Class I or III" does this imply that if there are two active ingredients (as in our case) both of them should be either class I or Class III.

What would be the interpretation for one drug being Class I and other being Class III, can still BCS biowaiver be claimed

Regards
Chirag

 FDCs biowaiver (Class I/III)

Hi Chirag!

BCS-based biowaiver are applicable for immediate release FC products if all active substances in the FC belong to BCS-class I or III and the excipients fulfil the requirements outlined in section IV.2. Otherwise in vivo bioequivalence testing is required.

What do you want to interpret here? You can apply for (not claim) a biowaiver if the APIs are either Class I or III.

API│         BCS       
───┼───────────────────
 1 │  I   III   I   III
 2 │  I   III  III   I
───┼───────────────────
BW?│ yes  yes  yes  yes
