RE:    NDA 20-121
         Flonase (fluticasone propionate) Nasal Spray, 50 mcg
         MACMIS ID#: 11542

Dear Ms. Ferrell:

This letter notifies GlaxoSmithKline (GSK) that the Division of Drug Marketing, Advertising, and Communications (DDMAC) has identified direct-to-consumer (DTC) advertisements (ads) for Flonase (fluticasone propionate) Nasal Spray that are in violation of the Federal Food, Drug, and Cosmetic Act (Act) and its implementing regulations.  Specifically, misleading claims about Flonase Nasal Spray have been broadcast in a 60 second radio ad ("Be Aware") and disseminated in a full-page print ad appearing in daily newspapers, including The Washington Post and USA Today.  Our specific objections follow.


Flonase is a prescription corticosteroid nasal spray indicated for the management of the nasal symptoms of seasonal allergic rhinitis (SAR), perennial allergic rhinitis (PAR), and perennial nonallergic rhinitis (PNAR). Allegra, Clarinex, and Zyrtec are oral prescription antihistamines ("allergy medicines") indicated for the relief of nasal and non-nasal symptoms for one or more types of allergic rhinitis (SAR or PAR).  Therefore, although Flonase is approved to relieve the nasal symptoms from more types of rhinitis than oral allergy medicines (including PNAR), Flonase is not approved to relieve as many symptoms (e.g., non-nasal symptoms such as, itchy/watery/red eyes) caused by seasonal or perennial allergic rhinitis.  FDA is not aware of any data demonstrating that Flonase provides comparable or superior effectiveness to any oral prescription antihistamines for these conditions.

Misleading "Allergy Relief" Effectiveness Claim

The radio and full-page DTC print ad contain the same or similar claims and representations.  Pertinent sections of the print ad include the following claims and representations:

What you don't know about
Clarinex®, Zyrtec®, and Allegra®
 may cost you.

                                 •  Be aware.


Many prescription plans
are raising the co-payment
cost of Clarinex®, Zyrtec®,
and Allegra®.  But 99%
of prescription plans
cover FLONASE.*



 Don't let allergy relief cost
 you more this year. Ask your
 doctor about FLONASE.
It's FDA-approved to relieve
The nasal symptoms from
More triggers than any
Leading^ allergy medicine.

Promotional materials are misleading if they state or suggest that a drug is useful in a broader range of patients or conditions than has been demonstrated by substantial evidence or substantial clinical experience.  The clear implication of the radio and print ads is that Flonase can be substituted for (i.e., works as well as) the antihistamines for "allergy relief," and that Flonase is actually more useful than the other allergy medicines. The ads misleadingly suggest that because Flonase is comparable or superior to the other "allergy medicines," the consumer need consider only the possible insurance copayment cost in considering switching to Flonase.

Flonase, however, a topical nasal spray, is neither therapeutically equivalent to the oral antihistamines nor interchangeable with or substitutable for them.  Unlike Allegra, Clarinex, and Zyrtec, Flonase has not been demonstrated to be safe and effective in treating any of the non-nasal symptoms of SAR, PAR, or PNAR.  It is therefore not therapeutically interchangeable with those allergy medicines.  The inclusion of the word "nasal" in a single disclosure in the middle of these ads does not mitigate the overall misleading impression that Flonase will relieve "allergies" as well as or better than these antihistamines.

Conclusions and Requested Actions

GSK should immediately discontinue the radio and print ads and all other promotional materials and activities for Flonase that contain the same or similar violative presentations. GSK should submit a written response to DDMAC on or before July 3, 2003, describing its intent and plans to comply with the above.  In its letter to DDMAC, GSK should include the date on which these ads and other similarly violative materials were discontinued.

GSK should direct its response to Joan Hankin by facsimile at (301) 594-6771, or in writing at the Food and Drug Administration, Division of Drug Marketing, Advertising, and Communications HFD-42, Rm. 8B-45, 5600 Fishers Lane, Rockville, Maryland 20857. In all future correspondence on this matter, please refer to MACMIS ID# 11542 well as the NDA number. DDMAC reminds GSK that only written communications are considered official.
