Precision Medicine: The Future of Medicine?

Reporter: Aviva Lev-Ari, PhD, RN

Dr. Laurie Glimcher, dean of Weill Cornell Medical College, and Dr. Robert Langer, the Koch Institute Professor at MIT, talk to the “CBS This Morning” co-hosts about what’s next in the fight against diseases like Alzheimer’s, cancer, and diabetes.

The Economics of Precision Medicine: 

How Personalizing Treatment can Bend the Cost Curve by 

Improving the Value Delivered by Healthcare Innovations

In a world where it is clear that healthcare costs must be contained, how can we afford to pay for innovation? This webinar will explore how personalizing treatment can offer an escape from the innovation-cost conundrum. By simultaneously increasing clinical development efficiency and the treatment effectiveness, targeting clinical innovations to the patients most likely to benefit can improve healthcare value per dollar spent while maintaining the ROI levels needed to support investment in innovation. We believe precision medicine should play a more prominent role in the cost containment discussion of healthcare reform.

By attending this Webinar, you will learn how to:

Help clients develop product development and commercialization strategies that get leverage from the benefits of precision medicine 

Support positioning of innovations as part of the healthcare solution, not the problem 

Understand and communicate the value proposition of precision medicine for payers, government decision makers, and legislators

Nanotechnology is simply defined as the technology to manipulate the matter on the atomic and/or molecular scale. It is generalized to materials, devices and structures with dimensions sizes at the nanoscale of 1 to 1000 nanometers (nm) (1,2).

Nanotachnology can be applied to many fields including sensors, biomaterials for tissue engineering, and nanostructures or 3D materials for molecular imaging and drug delivery among others. In medicine, nanotechnology is essentially a multidisciplinary field of physics, organic and polymer chemistry as well as molecular biology, pharmacology and engineering. These fields team up together to design a better and most opt treatment option for a disease using “the right drug, the right vehicle and the right route of administration”. In pharmaceutical industries, a new molecular entity (NME) that demonstrates potent biological activity but poor water solubility, or a very short circulating halflife, will likely face significant development challenges or be deemed undevelopable. There is always a degree of compromise, and such tradeoffs may inevitably result in the production of less-ideal drugs. However, with the emerging trends and recent advances in nanotechnology, it has become increasingly possible to address some of the shortcomings associated with potential NMEs. By using nanoscale delivery vehicles, the pharmacological properties (e.g., solubility and circulating half-life) of such NMEs can be drastically improved, essentially leading to the discovery of optimally safe and effective drug candidates. (3,4).

This is just one example which demonstrates the degree to which nanotechnology may revolutionize the rules and possibilities of drug discovery and change the landscape of pharmaceutical industries. (5)

Nanomedicine is facing many challenges in overcoming biological barriers, arrival and accumulation at the target site, therefore advances in nanoparticle engineering, as well as advances in understanding the importance of nanoparticle characteristics such as size, shape and surface properties for biological interactions, are necessary to create new opportunities for the development of nanoparticles for therapeutic applications (6).

Compared to conventional drug delivery, the first generation nanosystems provide a number of advantages. In particular, they can enhance the therapeutic activity by prolonging drug half-life, improving solubility of hydrophobic drugs, reducing potential immunogenicity, and/or releasing drugs in a sustained or stimuli-triggered fashion. Thus, the toxic side effects of drugs can be reduced, as well as the administration frequency. In addition, nanoscale particles can passively accumulate in specific tissues (e.g., tumors) through the enhanced permeability and retention (EPR) effect. Beyond these clinically efficacious nanosystems, nanotechnology has been utilized to enable new therapies and to develop next generation nanosystems for “smart” drug delivery (such as gene theraphy).

In summary; there are several factors that need to be included for a rational nanocarrier design:

–          Protect the drug from premature degradation

–          Protect the drug from premature interaction with biological environment

–          Enhance the absorption of the drug into the selected tissue-site

–          Improve intracellular drug penetration

–          Improve and control the drug pharmacokinetics and distribution profile.

Moreover there are several other factors that need to be taken into consideration to effectively influence the clinical translation of the drug delivery system (DDS) i.e materials that are biodegradable and biocompatible, easily functionalized, exhibit high differential uptake efficiency etc.(7-9).

In the next few chapters, we will try to address some of these factors as well as some examples that succeeded in the clinical setting as well as those who failed.
