The
91th meeting of the Vaccines and Related Biological Products
Advisory Committee was called to order at 8:30 a.m. EST on May 21, 2002 by the
Chair, Dr. Robert Daum. The meeting
addressed in Session #1: Prevnarâ for indication
in acute ottitis media, and
Session #2: Update on GSK Lyme Disease Vaccine (LYMErixä). Both Session
1 and 2 were open sessions.
Following is a summary of the discussion. Additional information and specific details may be obtained from the transcript of the meeting. The transcript may be viewed on the world wide web at: http://www.fda.gov/ohrms/dockets/ac/02acsdocs.htm. A copy of the agenda is attached.
Prevnar® for Acute Otitis
Media (AOM) Indication
The committee discussed an
additional proposed indication for PrevnarÒ “for active immunization of
infants and toddlers against otitis media caused by Streptococcus pneumoniae
due to capsular serotypes included in the vaccine (4, 6B, 9V, 14, 18C, 19F and
23F).”
Data supporting this
indication were provided from two controlled clinical trials:
1)
Finnish
Acute Otitis Media Trial (FinAOM)
2)
Northern
California Kaiser Permanente Efficacy Trial (NCKP)

* Spontaneous TM rupture
In
the Finnish study, vaccine efficacy was 57% (95%CI: 44%, 67%) for AOM episodes
due to vaccine serotypes, and 34% (95%CI: 21%, 45%) for all AOM episodes caused
by pneumococci, regardless of serotype. The Finnish study included myringotomy
and cultures of the middle ear, this was not true of the Kaiser study. Vaccine
efficacy for all causes of AOM, regardless of etiology, was 7% (95%CI: 4.1%,
9.7%), based on evidence from the Kaiser study, and 6% based on evidence from
the Finnish Study.
In
summary, the Committee concluded that data derived from two efficacy trials are
adequate to demonstrate efficacy of Prevnar® against AOM caused by vaccine
serotype. However, the committee expressed concern about the low efficacy (7%)
of the vaccine against AOM regardless of etiology and concluded that
substantial clinical benefit of Prevnar in reducing AOM regardless of etiology
had not been demonstrated. The Committee cautioned against including an
indication statement as proposed by the sponsor into the label and suggested
using qualifying language if an indication for AOM regardless of etiology were
to be added. Committee members cautioned
against promoting prevention of AOM as a benefit of PrevnarÒ in direct-to-consumer advertising because of
concerns about unrealistic public expectations. The Committee was concerned that promoting PrevnarÒ as an “AOM vaccine” could potentially
compromise confidence in the existing recommendations for the vaccine and trust
in the labeling that FDA puts on a vaccine. It was noted that an AOM indication
for Prevnar® could set precedence for licensure of additional pneumococcal
conjugate vaccines for prevention of AOM.
Discussion
points included:
Recommendations were as
follows:
FDA Update on the GSK-Lyme Disease Vaccine (LYMErixä)
The FDA informed the
committee members that GSK voluntary withdrew LYMErixä from sale
in February of 2002 and distribution was discontinued. GSK cited poor sales as
the reason for withdrawal. No further vaccinations are recommended, clinical
trial vaccination ended, Dear Doctor/Investigator letters were sent, and
refunds were given for returned vaccine. Complete safety follow-up will be
completed for all clinical studies and the Phase 4 post-marketing study is to
be completed in 2006.
Two Open Public Hearing sessions were announced. No one requested time to speak in Session #1. For Session #2 there were eight requests for speaking.
