Is there a path forward to treat Ebola?


We really need to focus on how we address diseases that affect the entire global community. Ebola, as a disease, while still in Africa is certainly something that can affect other communities across the globe. Right now, many treatment strategies are still sitting on the shelf... We all understand the risks of developing new medicines, but when big pharma cannot find a business case to get behind something like this, we all have a problem. Let's start a new hashtag #globalconscience4Africa 

Nature put out an interesting article on technologies sitting on the shelf that could address infectious diseases in general...  When will enough people globally or at least in developed countries die from Ebola so that making a vaccine for it becomes profitable to big pharma given the significant investment required in research and development on the front end? The economic factors driving the lack of efforts have not been sufficiently discussed in mainstream media. The focus has been more on whether and how it might spread. Public pressure on big pharma is non-existent because we view this as an African disease and therefore not important. We accept that there is no cure but don't discuss the politics and economics of vaccine development. African lives at stake, the potential global spread of the disease, and the incredibly high mortality rate make finding a treatment/cure paramount.

Liposomal delivery for lung infections

Liposomal delivery for lung infections

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.


Peptineo's Approach to Nanomedicine

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

Peptineo Inks Exclusive Option for Drug Delivery Technologies

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.

Crowd Sourcing for Medical Research

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.
