Dynavax Initiates Phase 3 Registration Trial For Hepatitis B Vaccine
Phase 3 lot-to-lot consistency trial is expected to begin in early 2010
Dynavax Technologies has announced the initiation of a phase 3 registration trial for Heplisav hepatitis B vaccine in individuals with chronic kidney disease. A second registration trial, a phase 3 lot-to-lot consistency trial, is expected to begin in early 2010.
Heplisav is a phase 3 investigational adult hepatitis B vaccine designed to provide protection with fewer doses than current licensed vaccines. Dynavax believes that these studies, taken together, could support registration filing of Heplisav with the FDA.
Dynavax’s phase 3 trial is enrolling approximately 600 patients with chronic kidney disease. After being randomised 1 to 1, patients will receive either 3 doses of Heplisav (at 0, 1, and 6 months) or 8 doses of the current licensed vaccine Engerix-B (2 doses at 0, 1, 2, and 6 months), said the compnay.
Dino Dina, president and CEO of Dynavax, said: "After achieving pivotal trial data demonstrating Heplisav’s clinical benefit, we currently expect to complete these two registration trials within the next 24 months. The unmet medical need for better hepatitis B vaccination for certain groups such as chronic kidney disease patients is significant and is a large, servable market opportunity for Dynavax."

The nano-enabled drug delivery market has been a high growth market and expected to grow at a faster rate in the near future. According to a study conducted by Willi Paul, and Chandra P. Sharma, the nano-enabled drug delivery market was $1.7 billion in 2009 and expected to reach over $4.8 billion in 2012. The market will witness increased competition, high investment from venture capitalist and government. The M&A and Licensing landscape will see significant changes in the coming future. This is because market is expected to become more lucrative in coming future. The major drivers for the market growth are Increasing acceptance of nano-enabled drugs, and a strong pipeline portfolio. The increasing governmental funding and R&D interest will strengthen the market in future. However, lack of consistent policy on technology transfer, poor R&D facility, and tight audit control and lack of centralized system will restrain the market growth. The nano-enabled drug delivery market has strong pipeline. The pipeline is primarily dominated by molecules in early stage of development. This suggests that the there is high level of R&D investment. This will support the future market and will fuel the licensing activity. Buy online from $3500
