Tests for new version of flu vaccine
LONDON (Reuters) - Vaccine maker PowderJect Pharmaceuticals says it has
started a Phase I clinical trial of a powder version of its top-selling flu
vaccine Fluvirin.
The company, which has pioneered needle-free injections using powdered
versions of drugs, said on Tuesday the trial would involve 36 healthy

response.
Flu is responsible for around 20,000 deaths in the United States each
year and more than 100,000 hospitalisations.
Analysts expect the market for flu vaccine to grow from around $700
million (450 million pouns) to $1 billion in five years time. Fluvirin was
the second-best selling flu vaccine in the world last year, with sales of
around 67 million pounds.
PowderJect sold its most of its powder injection technology to U.S. pain
management specialist AlgoRx Pharmaceuticals in March, but retained its use
in vaccines.
A PowderJect spokesman said the powdered version of Fluvirin would cost
around the same to make as a pre-filled syringe version, but would probably
sell at a premium.
Drugs have to pass three phases of clinical trials before coming to
market, a process which usually takes several years. |
