» 8:40 FEATURED PRESENTATION: Principles of Ligand-Targeted Drug Design
Philip S. Low, Ph.D., Ralph C. Corley Distinguished Professor, Department of Chemistry, Purdue University
Because targeted therapeutics treat pathologic cells without damaging normal cells, they will likely dominate the drug market of the future. In this presentation, I will discuss the basic principles underlying the successful design of ligand-targeted therapeutics, using multiple examples of ligand-targeted drugs currently in the clinic or late preclinical development to illustrate each major principle.
9:10 Centyrins: A Novel Scaffold for New Therapeutics
Karyn O’Neil, Ph.D., Chief Scientific Officer, Centyrex Venture, Johnson & Johnson
Alternative scaffolds share properties with antibodies in terms of their specificity and potency and with small molecules in terms of simplicity and size. The Centyrin platform, a consensus fibronectin domain, has been optimized to enable selection of Centyrins that inhibit multiple classes of proteins. We will describe how the biophysical properties of Centyrins make them ideal for novel therapeutic applications including drug conjugates and targeted nanoparticles.
9:40 Development of Novel Targeted Cancer Therapies with BIND Accurins™
Jeff Hrkach, Ph.D., Senior Vice President, Technology Research & Development, BIND Therapeutics
Accurins™ are a new class of highly selective targeted therapeutics, precisely engineered to have long circulation half-lives, high drug loading levels, finely tuned pharmacokinetics and surface-bound targeting ligands that bind selectively to cell-surface receptors on diseased cells. Accurins achieve high and prolonged concentrations creating optimal therapeutic indices. BIND is developing Accurin targeted therapeutics, primarily focused on oncology.

10:40 NanomAbs: New Leap in Antibody-Drug Conjugates
Stephane E. Allard, Ph.D., CMO, EpiCept Corp.
NanomAbs platform is a conjugate of a targeting moiety to chemotherapeutic drug loaded polymeric nanoparticles. Development of Immune’s linker technology enabled the optimized drug to mAb ratio using the mAb as a targeting moiety. Extensive preclinical research recently showed improved anti-cancer effect in several cancer models and beneficial safety profile. Leveraging the technology for targeted combo cancer drug delivery is underway showing synergistic effects in advanced tumors.
11:10 Addressing the Delivery Challenge for siRNA Therapeutics
Marian Gindy, Ph.D., Director, Pharmaceutical Sciences, Merck Research Laboratories
siRNA represents a promising therapeutic strategy, with potential to access molecular targets considered undruggable by small molecule and protein therapeutics. Challenge toward realizing this technology is the safe and effective delivery of siRNA to target tissues. siRNAs properties prevent diffusion across most cell membranes, requiring the use of delivery systems to confer intracellular access. Presentation will illustrate the development of such oligonucleotide delivery technologies.
11:40 Nanopharmaceutical Delivery of Toxic and Biodegradable Drugs: Case Studies of Camptothecin and siRNA
Sonke Svenson, Ph.D., Director, Research, Cerulean Pharma, Inc.
Cerulean’s nanopharmaceutical technology consists of polymeric nanoparticles carrying drug molecules conjugated to the constituent polymers. Encapsulation protects the body from toxic drugs, and protects biodegradable drugs from enzymatic or hydrolytic metabolism inside the body. Chemical conjugation of drug molecules to the carrier prevents burst release in favor of controlled drug release from the nanopharmaceuticals.

2:10 Visualizing Targeted Delivery of Polymer-Drug Conjugates
Ban-An Khaw, Ph.D., George D. Behrakis Professor of Pharmaceutical Sciences, Department of Pharmaceutical Sciences, School of Pharmacy, Northeastern University
Most chemotherapeutic agents are not target specific. They can be made target specific by antibody-drug conjugate technology. To improve targeting ability and highly efficient delivery of drugs, bispecific antibody complex pretargeting and targeting with polymer-drug conjugates (PDC) was developed. Targeting with radioisotope labeled or chemotherapeutic PDCs enabled visualization of very small cancer lesions, and therapy was as efficient as free drug but has no non-target toxicity respectively.
2:40 PET Imaging of Antibodies for Evaluation of Distribution, Clearance and PK in vivo
Vania Kenanova, Ph.D., Head, Preclinical PET/SPECT/CT Imaging Laboratory, Global Imaging Group, Novartis Institute for Biomedical Research
Quantitative PET imaging is routinely used for evaluation of antibodies in vivo. This involves radiolabeling of the antibody either by attaching radionuclide directly (I-124 to Tyr) or via a chelate (NODAGA [Cu-64], desferal [Zr-89]). The PET image is a result of the catabolism and clearance of the protein, chelate and radiolabel. This talk will go over the distribution and clearance of radiolabel alone, radiolabel-chelate and radiolabel-(chelate)-protein for PK analysis.
3:10 Facile Synthesis of Multifunctional Imaging Nanoparticles
Robert K. Prud’homme, Ph.D., Professor, Department of Chemical & Biological Engineering, Princeton University
Composite nanoparticles can be made is a single step process by block-copolymer-directed rapid precipitation to incorporate both therapeutic and imaging agents into the same nanoparticle. A wide range of imaging nanoparticles can be prepared using the same platform, and the process is scalable from the laboratory (mg) to manufacturing scale (kg). Examples will be presented of fluorescent dyes, MRI contrast agents, up-converting phosophors, and SPEC imaging nanoparticles.
3:40 Refreshment Break in the Exhibit Hall with Poster Viewing
4:10 Nanoscale Evaluation of Novel Dendritic Nanocarriers for Cancer Targeting
Seungpyo Hong, Ph.D., Assistant Professor of Pharmaceutics and Bioengineering, Department of Biopharmaceutical Sciences, University of Illinois College of Pharmacy
Although a myriad of promising nanocarriers have been recently developed, targeted drug delivery to cancerous regions still remains a tremendous challenge. This presentation will focus on new drug delivery platforms based on dendritic structures to take advantage of multivalent binding and enhanced self-assembly. Fundamental understanding as well as biological testing of those novel nanocarriers will be discussed.
