The companies will collaborate to create and test circVec DNA–LNP formulations for use in potential therapeutic applications.
Accurately targeted immunotherapies through reliable neoantigen recognition enable personalized medicine development.
Enhanced brain drug delivery and targeting
April 1st 2008The blood–brain barrier (BBB) forms an interface between the circulating blood and the brain, and functions as a tremendously effective barrier for the delivery of potential neurotherapeutics into the brain parenchyma. Conversely, the BBB possesses various carrier-mediated transport systems for the uptake of small molecules, such as essential nutrients and vitamins. These transporters have become an attractive target for drug/prodrug design in an attempt to ferry drug molecules across the BBB. Central nervous system (CNS) drug delivery is often limited by poor brain penetration of the potential drug candidate. As a result of its unique barrier properties, the BBB poses a huge challenge for the delivery of potential neurotherapeutics into the brain parenchyma.1 It is estimated that only 2% of small-molecule drugs and ,0.1% of novel protein and peptide pharmaceuticals developed for CNS diseases reach therapeutic concentrations in the brain.2,3 Many of the pharmacologically active drugs tend to fail..
Advances in Radio-Frequency Transdermal Drug Delivery
April 1st 2008A microelectronic system based on radio-frequency (RF) cell ablation addresses limitations of other transdermal drug-delivery methods. This system expands the transdermal spectrum to include the delivery of water-soluble molecules, peptides, proteins, and other macromolecules.
Polypeptide Multilayer Nanofilms in Drug Delivery
April 1st 2008Investigators are exploiting the tremendous structural diversity of polypeptides and their biophysical properties to develop novel drug carriers. Peptide-based materials hold out much promise for tailor-made targeting, penetration, and release of contents in a host of biological microenvironments.
Dissolvable Films: Dissolvable Films for Flexible Product Format in Drug Delivery
April 1st 2008For pediatric and geriatric patients, fast-dissolving drug-delivery systems provide an easier way to take medications and vitamins. Oral thin films have evolved to provide systemic delivery of active pharmaceutical ingredients for over-the-counter and soon, prescription drugs. The authors review the practical benefits of dissolvable films, their manufacture, and their market potential.
Challenges in the Secondary Manufacture of Encapsulated High-Potency Drugs
April 1st 2008Liquid and semisolid encapsulation using two-piece hard capsules is an ideal drug delivery approach for highly potent compounds and poorly water-soluble drugs. The authors detail the factors to reduce risk when designing and operating a facility for secondary manufacturing of highly potent drugs.
