GlaxoSmithKline plc (ADR) sees little threat to its top selling drug Advair from generic competition, according to GlaxoSmithKline Chief Executive Andrew Witty.
Speaking at the JPMorgan Healthcare Conference, Mr. Witty said that it is very difficult to make a generic and that he has not heard any thing this week that would make him change his mind. Advair could encounter competition in the key US market in 2011 but the drug is delivered by an inhaler. This will complicate matters for generic producers.
It will also be difficult for generic producers to get approval for a generic version of Advair as a straightforward substitute. Mr. Witty also said that GlaxoSmithKline was in the process of producing generic versions of its drugs that will be losing patent protection.
