Talk about the Strategies to Increase the Number of Excipients Labeled USP-NF October 10-11, 2006 DISCUSSION TOPIC D Closing Presentation Moderator: Barbara Ferguson Scribes: Catherine Sheehan Dr. Hong Wang

Slide 2

1.a. What are the boundaries to naming an excipient as USP-NF review? Low request, not principle business, may charge premium for USP-NF review, might be a by-item and not last excipient GMP necessities are seen to be excessively stringent Difficult for synthetic provider, making it impossible to come up to speed with GMPs Lack of excipient maker's comprehension of what prerequisites, outside of the USP-NF monograph, should be met, including GMP necessities Many monographs created before foundation of GMP necessity for excipients PQRI Workshop Discussion D

Slide 3

1.a. What are the hindrances to marking an excipient as USP-NF review? Try not to need to put NF on the name in light of the risk to meet different necessities notwithstanding monograph prerequisites. The Act 501b does not recognize the medication and the excipient in the medication, so the necessity to follow USP-NF exists if the excipient make supplies the medication advertise. Require lucidity on this point from FDA . Client needs to comprehend why the seller won't confirm material as USP-NF to guarantee that it won't affect nature of item PQRI Workshop Discussion D

Slide 4

1.a. What are the boundaries to marking an excipient as USP-NF review? Time/assets for reviews more than one review by a firm Pharmaceutical maker evaluators erroneously apply tranquilize GMPs to excipients diverse necessities for every examiner/firm don't comprehend excipient prepare use review check list attitude utilize terms for medication GMPs which are not relevant to excipient control PQRI Workshop Discussion D

Slide 5

1.a. What are the hindrances to naming an excipient as USP-NF review? Absence of comprehension of utilization of excipient in detailing Needs to be a comprehension amongst creator and client in regards to the fundamental capabilities Purchasing purchases the material - gets you shabby excipients, not great science Scientist/formulator ought to speak with merchant for vital qualities/utilization of excipient Insurance/inward prerequisites to qualify two wellsprings of excipients Excipient makers differ (some will supply the pharmaceutical market, some won't, some are completely devoted to the medication/sustenance industry, some are compound producers) Monograph testing does not give off an impression of being a contributing variable PQRI Workshop Discussion D

Slide 6

1.b. In what capacity can the obstructions be decreased? Cultivate better comprehension by excipient makers and medication item makers in regards to the suitable GMPs for excipients – see #6 for proposals Provide direction to teach both sides with respect to what is required/expected – see #6 for suggestions Audits concentrate on seller's control of excipient process arrange reviews from the medication item producer use outsider reviews after introductory capability May even now come down to the main issue: Is there a sufficient market to supply this review? PQRI Workshop Discussion D

Slide 7

2. What excipients are no longer accessible as USP-NF review, which were once in the past accessible as USP-NF review? In the event that there is no USP-NF review excipient financially accessible, then there is nobody to bolster the continuation of a monograph; USP monograph is erased Recommend holding monograph as least standard the length of there is no wellbeing issue Monographs that have been discarded (erased) Dehydroacetic corrosive (proposition to be restored) Propylene glycol diacetate Gentisic corrosive ethanolamide Can the erased rundown be distributed? USP will reestablish monograph if provider will bolster it Some illustrations accommodated merchants no longer affirming material as USP-NF (e.g., methanol in tankers) Can Distributor accept risk and call it USP-NF on the off chance that they perform last handling venture under GMPs? PQRI Workshop Discussion D

3. What are the suggestions when an excipient client moves from a compendial review excipient to noncompendial review (i.e., not assigned through marking postfix, to be specific USP-NF , Ph. Eur. on the other hand JP), when it was beforehand secured as compendial review? Tranquilize item maker expect obligation if keeps on utilizing material need to know why it is not USP-NF might utilize same process, but rather are controls the same? Need to change administrative recording, if pertinent Changes to administrative filings could be expensive (e.g., Europe) Look for another provider PQRI Workshop Discussion D

Slide 9

3. What are the suggestions when an excipient client moves from a compendial review excipient to noncompendial review (i.e., not assigned through naming postfix, in particular USP-NF , Ph. Eur. on the other hand JP), when it was already secured as compendial review? Regardless of the possibility that monograph is kept up, testing alone is deficient – require more prominent confirmation, perhaps through reviews If comes up short when tried, tranquilize item maker accept chance/misfortune Justification to move from compendial to noncompendial review If monograph is erased, can reference last authority rendition of USP-NF monograph in administrative documenting PQRI Workshop Discussion D

Slide 10

4. What is industry's weight in providing systematic technique approval information to administrative office for excipients no longer marked USP-NF ? If not utilizing USP-NF strategy, then medication item maker is required to give this in documenting, if material Method should in any case be equipped for controlling nature of the excipient Reference earlier form of USP-NF , if still proper for excipient , no extra approval should be provided Refer to Ph. Eur., JP, FCC, ACS Reagent Grade, or AOAC – no extra approval should be provided Refer to excipient producer's DMF, no extra approval should be provided Validation required for different techniques used to control excipient PQRI Workshop Discussion D

Slide 11

5. What test techniques are utilized when an excipient client must supplant a compendial review excipient with noncompendial review? ACS Reagent Grade, FCC, AOAC, JECFA Excipient seller strategy Noncompendial excipient area of recording May need to send supplement to FDA PQRI Workshop Discussion D

Slide 12

6. What are the continuous activities at the USP to address these issues? Monograph advancement rule on USP site with excipient area Provide more foundation/approaches on tests – "specialized guide" Outreach projects to industry – USP staff accessible to help with improvement of monographs USP General Information Chapters for Excipients <1078> GMPs (official however is being overhauled to reflect current IPEC) <1080> CoA (coming soon) <1195> Significant Change (coming soon) Excipient capability rules being produced by IPEC and will in the end be incorporated into USP I - Excipient maker (new proposition soon) II - Excipient client (being drafted by IPEC) III - Negotiation handle (later) USP lab may help with corrections to monographs (e.g., glycerin) PQRI Workshop Discussion D

Slide 13

6. What are the progressing activities at the USP to address these issues? Proposals: Reach out to merchants and non conventional USP-NF providers. Utilize USP Annual Science Meeting as a discussion to connect and instruct the non customary USP-NF clients. The merchants, once instructed, could help with teaching the excipient sellers. Build up Excipient Stakeholder Forum Utilize USP check program to decrease the measure of reviews. Set up a procedure for sellers to inform USP in the matter of when the NF review is no longer accessible. FAQs on USP site More straightforwardness for PDG Harmonization upgrades – USP site connection to EDQM's PDG status reports PQRI Workshop Discussion D

Slide 14

Section 501b of the Act does not recognize the medication and the excipient in the medication, so the prerequisites to agree to USP-NF exists if the excipient produce supplies the medication advertise. This could bring about excipient produces to evacuate "NF" from their name. Expelling the "NF" assignment from the mark does not deter the prerequisite to consent to the compendial gauges if the excipient is tended for use in the make of a medication item. That is on account of segment 501 (b) of the FD&C Act applies if the excipient implies to be or is spoken to as a medication the name of which is perceived in the official abridgment. Shutting Questions/Comments

Slide 15

What is industry's weight in providing systematic technique approval information to administrative organization for excipients no longer named USP-NF? Allude to excipient producer's DMF, no extra approval should be provided. In the event that the Drug Manufacturer utilizes the excipient producers DMF does the Drug Manufacturer needs to supply the approval? No extra logical techniques approval information should be provided in a (shortened, or) new medication application (NDA or ANDA), if FDA decides the DMF to be sufficient in support of the NDA/ANDA.
