Hi Tracy,

The justification is in the draft SBRA. Natalya can also comment, as she may have a memo. Here it is:

OBRR reviewed information from this application and determined that referral to the Blood Products Advisory Committee (BPAC) prior to licensure is not needed for the following reasons (FDAAA [HR 3580-138 SEC. 918: REFERRAL TO ADVISORY COMMITTEE]):

 

1.  New molecular entity provision (NME) does not apply to EVARREST as it does not represent a historically novel product class. Fibrin sealants have been used as an adjunct to hemostasis since the late 1970’s in Europe and since 1998 in the United States (TISSEEL manufactured by Baxter was approved by FDA in May 1998).

 

2.   The mechanism of action of fibrin sealants (fibrinogen/thrombin products) and their function in blood coagulation and control of local hemorrhage is well studied and understood. Upon contact with the bleeding wound surface, the fibrinogen-thrombin reaction initiates the last step of the coagulation cascade – formation of a fibrin clot.

 

3.   The Biological Components of EVARREST are ---b(4)------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Both components of the Backing layer -----------------------------------------------------------b(4)----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 

4.   A similar combination fibrin sealant product TachoSil (Takeda

Pharmaceuticals / Nycomed) has been used in European Union since

2004 and was approved by FDA in 2010 (STN 125351) as an adjunct to hemostasis in cardiovascular surgery where standard techniques are insufficient.

 

5.   The overall clinical program to evaluate efficacy and safety of EVARREST

was adequate and did not raise any major concerns.

 

6.   Review of information submitted in the BLA for EVARREST did not raise any controversial issues or pose unanswered scientific questions which

 

would have benefited from advisory committee discussion and recommendation.

 

 

 

Thanks, Kimberly

Hi Kimberly,

 

Do you have a justification memo regarding why this submission did not have to go to an

Advisory committee? It’s needed for the LARM. Thanks,

Tracy

Tracy,

Natalya, is the chair and I will defer to her to respond to the general questions once she seeks input from all review disciplines.

 

As for the clinical:

 

1. Does this resubmission warrant an Advisory Committee review? If so, please list pertinent advisory committee information or provide justification   otherwise.

I do not anticipate that an advisory committee review will be necessary.

 

2. Does this resubmission warrant PREA?

This submission does trigger a PREA review.

 

3. Do you continue to require a CDRH consult or like to keep the current CDRH consult on this file? If so, please let me know. A consult request was previously generated that can be modified for the resubmission.

Please retain the current CDRH consultants for continuity. I can assist preparing in the consult request for Roxi Horbowyj.

 

Kimberly
