Pfizer Makes Move Into Biologic Drugs
By ANDREW POLLACK
Making a new move into the fledgling market for generic biotech drugs, pharmaceutical giant Pfizer has acquired worldwide rights to sell human insulin and insulin analogs being developed by Biocon, one of India’s largest biotech companies. (Read More: http://prescriptions.blogs.nytimes.com/2010/10/18/pfizer-makes-move-into-biologic-drugs/) . . . that since the pathway for biogenerics has not yet been established, Biocon plans to conduct a phase 3 clinical trial of its insulin and to seek approval under an existing pathway known as rule 505(b)(2).
The first biologic for oncology is not coming off the patent protection until 2014. Herceptin's and Rituxan/MabThera's patents expire in 2014 and 2015 and Avastin is covered till 2017. The Pfizer’s move leads me to predict that companies will be more inclined to establish their own subsidiaries to manufacture and market “cheaper-priced-branded-drugs” once the patent and FDA protections expire. The nature of biologics is on their side – biosimilars will be just “similars” not “same” as long as parts of manufacturing are protected under Trade Secrets.
