Delivery Technologies for Protein Therapeutics: Assessment and Outlook

Delivery Technologies for Protein Therapeutics: Assessment and Outlook published by Insight Pharma Reports in March, 2007. This report consists of 185 pages and the price starts from US $ 1498.

Introduction

Abstract

Some of biotech' s most celebrated successes include:

• clotting factors
• anticoagulants
• modern insulins
• growth hormone
• follicle-stimulating hormone
• hematopoietic growth factors
• interferons
• interleukins

What do they have in common? They are therapeutic proteins, a market segment that had $34 billion in sales in 2004 and will have a projected $52.2 billion in sales in 2010*. As patents on first-generation proteins wind down, their owners naturally seek to protect their markets against interlopers. And in current and future battles for market share, protein delivery technologies are major weapons of offense and defense. It is a safe bet that if a therapeutic protein is bringing in big money and its patent is nearing expiration, someone somewhere with a clever technology is planning a market invasion based on improving how the protein is delivered. Delivery Technologies for Therapeutic Proteins: Assessment and Outlook analyzes and assesses protein delivery technologies developed by companies that are targeting:

• improved insulin delivery
• improved erythropoietin delivery
• improved interferon delivery
• improved growth hormone delivery

The report also analyzes and assesses noninjection delivery technologies, including technologies for:

• transdermal protein delivery
• oral protein delivery
• pulmonary protein delivery
• nasal protein delivery

Delivery Technologies for Therapeutic Proteins: Assessment and Outlook provides a thorough analysis and assessment of technologies for protein half-life extension and technologies for delivery of protein therapeutics.
