 16             DR. CHESNEY:  Thank you.  Now Tom Perez

 

 17   will read the meeting statement.

 

 18                        Meeting Statement

 

 19             DR. PEREZ:  Thank you and good morning.

 

 20   The following announcement addresses the issue of

 

 21   conflict of interest with regard to the adverse

 

 22   event reporting session and is made part of the

 

                                                                 8

 

  1   record to preclude even the appearance of such at

 

  2   this meeting.

 

  3             Based on the submitted agenda for the

 

  4   meeting and all financial interests reported by the

 

  5   committee participants, it has been determined that

 

  6   all interests in firms regulated by the Center for

 

  7   Drug Evaluation and Research present no potential

 

  8   for an appearance of a conflict of interest at this

 

  9   meeting, with the following exceptions:

 

 10             In accordance with 18 USC 208(b)(3), full

 

 11   waivers have been granted to the following

 

 12   participants, Dr. Richard Gorman for ownership of

 

 13   stock in a company with a product at issue, valued

 

 14   between $50,001 to $100,000; Dr. Judith O'Fallon

 

 15   for her and her sponsor's ownership of stock in a

 

 16   company with a product at issue, between $5,001 and

 

 17   $25,000; Dr. Katherine Wisner, for her speaker's

 

 18   bureau activities for a company with a product at

 

 19   issue for which she receives less than $10,001 per

 

 20   year; Dr. Patricia Chesney for her spouse's

 

 21   ownership of stock in a company with a product at

 

 22   issue, valued from $5,001 to $25,000 and unrelated

 

                                                                 9

 

  1   consultant earnings less than $10,001 per year.  In

 

  2   addition, Dr. Chesney's spouse owns stock in a

 

  3   company with a product at issue, worth less than

 

  4   $5,001.  Because this stock interest falls below

 

  5   the minimis exception allowed under 5 CFR

 

  6   2640.202(b)(2), a waiver under 18 USC 208 is not

 

  7   required.  Further, Dr. Chesney is recused from

 

  8   participating from the subcommittee's discussion

 

  9   regarding Duragesic due to a conflict of interest.

 

 10             A copy of the waiver statements may be

 

 11   obtained by submitting a written request to the

 

 12   agency's Freedom of Information Office, Room 12A-30

 

 13   of the Parklawn Building.  In the event that the

 

 14   discussions involve any other products or firms not

 

 15   already on the agenda for which an FDA participant

 

 16   has a financial interest, the participants are

 

 17   aware of the need to exclude themselves from such

 

 18   involvement and their exclusion will be noted for

 

 19   the record.

 

 20             We would also like to note that Dr. Samuel

 

 21   Maldonado has been invited to participate as an

 

 22   industry representative, acting on behalf of

 

                                                                10

 

  1   regulated industry.  Dr. Maldonado is employed by

 

  2   Johnson & Johnson.  With respect to all other

 

  3   participants, we ask in the interest of fairness

 

  4   that they address any current or previous financial

 

  5   involvement with any firm whose product they may

 

  6   wish to comment upon.  Thank you.

 

  7             DR. CHESNEY:  Thank you.  Our first

 

  8   speaker for the morning will be Dr. Dianne Murphy,

 

  9   Director of the Counter-terrorism and Pediatric

 

 10   Drug Development Office.

 

 11                             Welcome

 

 12             DR. D. MURPHY:  And just as you all

 

 13   understand how those two got to be combined, we

 

 14   have come to the end of an era.  That was really

 

 15   the substance of my opening comments this morning

 

 16   and I am going to talk more about this later in the

 

 17   day, that this is a milestone.

 

 18             But I wanted to take this morning to focus

 

 19   on the importance of the activity of this committee

 

 20   in the review of the safety or adverse events that

 

 21   occur after a product has been granted exclusivity.

 

 22   It has been clearly legislatively mandated that

 

                                                                11

 

  1   this is going to occur and that task has come to

 

  2   this committee.

 

  3             I wanted to make sure that you all

 

  4   realized how much you have contributed to this

 

  5   process.  We have received feedback from you during

 

  6   the time about what was useful and have tried to

 

  7   maintain a course, as we have to, that obeys the

 

  8   legislative intent and, yet, makes it more

 

  9   scientifically interesting within the constraints

 

 10   that we have.  I think probably years from now we

 

 11   could come and ask you all what are the problems

 

 12   with the AERS data reporting system.  So, you have

 

 13   been mandated to participate in a process in which

 

 14   you were told every meeting that you come here that

 

 15   the limitations are numerous with passive

 

 16   reporting; that when we do get reporting it is

 

 17   either poor or limited in nature; that there is

 

 18   little ability to go back and reconstruct in detail

 

 19   any of that information; and it basically doesn't

 

 20   have the same quality as a prospective surveillance

 

 21   or active process.  Yet, during this time I think

 

 22   we have evolved a process, again with your feedback

 

                                                                12

 

  1   and assistance, that has allowed us to make it more

 

  2   valuable.

 

  3             I would like to say that I think that what

 

  4   we have been able to identify over the past year or

 

  5   so has been the benefits of this system, and that

 

  6   is that it ensures that attention is focused on

 

  7   what is happening postmarketing to these products

 

  8   that the government initiates and rewards for

 

  9   studies being conducted.  As most of you are aware,

 

 10   one of the largest safety databases that occurs

 

 11   with any product is the postmarketing activities.

 

 12   That is where you find your rare serious events.

 

 13   And, this process has been critical for this

 

 14   committee and this has been a very important

 

 15   activity that I do think has focused and ensured

 

 16   that products that are marketed for children are

 

 17   looked at in a studied way, a reliable way, a

 

 18   predictable way, and I think that that is

 

 19   important.

 

 20             Now, why is it important?  Because I don't

 

 21   know how many times you have sat through these

 

 22   meetings where we said, "well, here are the

 

                                                                13

 

  1   problems and we didn't see anything.  Okay?"  But

 

  2   that is good news.  We would hope that the majority

 

  3   by far, if not 100 percent of these products that

 

  4   are studied and marketed don't have serious hidden

 

  5   adverse events.  So, in a say, it is like

 

  6   prophylaxis.  We hope we don't find major issues.

 

  7             But I think the other thing that this

 

  8   process has done that I wanted you all to know

 

  9   about that was important is that it has the effect

 

 10   on the agency of re-prioritizing pediatric safety

 

 11   assessments.  As everyone knows, there are many

 

 12   deadlines the agency has to meet and it is hard

 

 13   often to see the plate for all the things that are

 

 14   on it.  But clearly the legislation, your

 

 15   participation and our c
