This trial was the first step in a phase 3 trial to determine if Inavir has a prophylaxis effect.
Ads you can see from the BTA annoucement it certainly does. A MAJOR SUCCESS. The next trial is a more conclusive study under tighter perimeters.
Look at the Original DS annoucement on this study.
'Tokyo, Japan -- November 5, 2009 -- Daiichi Sankyo Co., Ltd. today announced that it has launched a new Phase 3 trial of its anti-influenza agent, CS-8958. The goal is to gain an influenza prevention indication in Japan.
The trial is placebo-controlled, double-blind and will evaluate preventive effect and safety of CS-8958 in families of influenza A and B sufferers. Daiichi Sankyo will measure influenza transmission among those receiving CS-8958 or placebo. We expect to observe that inhaled CS-8958 administered once weekly shows the prophylaxis effect.
CS-8958, a novel neuraminidase inhibitor discovered by Daiichi Sankyo for the treatment of influenza is co-owned with Biota Holdings Limited, and is a laninamivir prodrug. This inhaled formulation will be single-administered, acting directly on the trachea and lungs to inhibit influenza.
Daiichi Sankyo is pressing ahead with the development program of CS-8958 in Japan. We are preparing to submit an application for manufacturing and marketing approval by March 2010 to the Japanese Ministry of Health, Labour and Welfare for CS-8958 to treat adult and pediatric patients.
The trial is named SHIELD (a Study of Household Influenza prophylaxis Effect of Long-acting anti-influenza Drug).'
