Our World ADC 2016 Presentation
The World ADC Summit in San Diego was held October 10-13, 2016. This was the 7th Annual World ADC Summit. On October 11, 2016, our company president, Paul D. Davis, presented his talk titled, “Using the dPEG® as the Framework to Uniquely Load and Protect Payloads in an ADC Format …with dPEG® single molecule precision.” See Figure 1.

The World ADC Summit is the premiere conference for discussing antibody drug conjugates (ADCs). Quanta BioDesign, Ltd. has attended every summit in San Diego since they began.
First, Paul discussed dPEG® chemistry (what it is and why you need it). Then he provided a great visual visual contrast between standard polydispersed PEGs and discrete PEGs (dPEG®s). Even with a dispersity (PDI) of 1.01, the number of different species in the dispersed PEG is astonishingly large! See Figure 2.

The Highlight of our World ADC Presentation
In addition, and as the highlight of his talk, Paul discussed our new, patent-pending Sidewinder™ dPEG® platform. See Figure 3, below. This revolutionary new platform is designed for our customers who are developing ADC products. Sidewinder™ provides a stable, non-immunogenic platform with diverse reactive groups to allow conjugation of useful diagnostic or therapeutic compounds onto the platform. In order to optimize physiochemical properties such as pharmacokinetics (PK), pharmacodynamics (PD), and biodistribution (BD), modulating arms extend from the distal end of the platform. And these arms can be tailored to our customers’ precise needs.

Paul also showed off a bit. For successful ADCs, a high drug-to-antibody ratio (DAR) is critical. As DAR increases, ADC efficacy increases. Our Applications group demonstrated that Herceptin® (trastuzumab) could be fully reduced and conjugated to eight (8) Sidewinder™ platforms. Each platform contained three loading points, giving us a proof-of-concept that a DAR of twenty-four (24) is possible with Sidewinder™. See Figures 4, 5, and 6, below. This was one of the highlights of the talk, and after the talk, our booth at World ADC was full of people wanting to know more about our product.
