Insmed continues to work to delivery therapeutics to the lung for the treatment of nontuberculous mycobacterial lung infections (NTM). Although the company has been recently punished by the investor community over results that failed to meet expectations, work continues on this promising therapeutic. Arikayce, or inhaled liposomal amikacin, is now being positioned for breakthrough discovery status. Once again, we see the promise of therapeutic nanomaterials coming closing to mainstream application.
Harvard manipulates chemical gradients to produce incredibly intricate structures that resemble flowers. Wim L. Noorduin, a postdoc at Harvard, has found a way to manipulate the growth of crystals and produce exquisite structures. http://ow.ly/x3C5f
An excellent overview of nanomedicine from the European Union (EU). It describes perfectly technologies being developed by Peptineo. Peptineo, a nanotechnology company based in Albuquerque, New Mexico, is currently developing commercial technologies around the use of novel polymeric materials for drug delivery applications. In particular, one material under development, acetalated dextran (Ac-DEX), has recently been used as the basis for a novel vaccine under the direction of noted academic researchers and the US Department of Defense, Defense Advanced Research Projects Agency (DARPA). Ac-DEX is also being reviewed for applications in which it could facilitate the re-introduction of failed late-stage drug candidates into the regulatory approval process. In this case, it is anticipated that through its ability to precisely control the release of active pharmaceutical ingredients (APIs), Ac-DEX will offer a significantly better safety profile in numerous therapeutic applications. Peptineo is looking forward to sharing details about Ac-DEX based materials soon
ALBUQUERQUE, New Mexico- Peptineo, a privately held biotechnology company, announced today that the company has inked an exclusive option for a broad set of nanotechnology patents in the area of drug delivery. Under this agreement, Peptineo will work to commercialize drug delivery technologies developed in the laboratories of Dr. Carolyn Bertozzi and Dr. Jean M.J. Fréchet. “Securing an option agreement marks a significant event in the evolution of Peptineo and will enhance on-going research efforts within the company,” noted Dr. Sheldon Keith Jordan, CEO. “For Peptineo, Dr. Bertozzi’s and Dr. Fréchet’s collective body of research represent the highest standard of scientific expertise and will afford Peptineo multiple opportunities to address unmet drug delivery challenges in many therapeutic areas,” commented Dr. Jordan.
While it is often useful to release therapeutic agents under mildly acidic conditions, few existing materials developed for drug delivery are both acid-sensitive and biodegradable/bioerodible. To address this gap, Jean Fréchet and a team of scientists have developed a new class of polymers that can encapsulate proteins, DNA/RNA-based materials, and other bioactive agents for vaccines, drug delivery, and gene therapy. A key feature for this class of polymers is that they can be employed in any application that necessitates materials with precise control over the release of encapsulated cargoes. In the human body, these polymers will be able to quickly release their payloads or be eroded over time -breaking down into neutral byproducts that can be safely eliminated. Materials made from the polymers can be engineered to degrade at specific rates, ranging from a day to many months at physiological pH, depending on the formulation used. Additionally, these same materials will allow for greater variation in the type of encapsulated therapeutic materials, targeted cell types, and drug release kinetics than are currently available -including microencapsulation materials like poly-(lactide-co glycolic acid) (PLGA).
With regard to research efforts led by Carolyn Bertozzi, she and her colleagues have developed a method for creating high-purity, nano-sized polymer particles that display specific biological ligands on their surfaces. The resultant nanoparticles are hollow, spherical, polymerized liposomes that bind to biological targets and can be used as an inhibitor or be used for delivering a drug loaded in its interior. This technology forms the basis for a new class of materials that have great therapeutic potential. Briefly, the material starts out as a membrane in the spherical form of a liposome that is self-assembled from individual monomers. Monomers that bind to pathogens (such as influenza virus) or bind to disease sites in-vivo (inflamed tissue) are incorporated into the self-assembling mixture –thereby providing critical in-vivo targeting capabilities. Finally, a quick and efficient polymerization by light gives a solid shell to the resultant nanoparticle.

Found a great article on futuretech in the Biomanufacturing space. Xcellerex has quietly become one of the emerging leaders in this field. As a result, this company was acquired by General Electric GE.
There is a great site out on the web. This site employs crowdfunding to help support medical research. As you skim the site, you see projects ranging from cancer research to lung transplants. Surprisingly, several of the projects are fully funded. It is definitely worth a look.
Cytos is an interesting company developing vaccines using virus-like particles based in bacteriophage Q-beta. Their approach is unique in that they conjugate proteins to the structure to target diseases of interest.
