This is the ninth article in a review series on Nanomedicine. We reviewed the major research and entrepreneurial development of nanomedicine and the relevant patent landscape (Part I and Part II). The first topic we discussed was Organs-on-a-chip (Part III). Here, we continue our discussion in this field with focus on entrepreneurial developments. We also have other reviews about nanoparticles for drug delivery (Part IV), cancer therapeutics (Part V), and bio-imaging (Part VI). We also included a discussion about functional nanoparticles: quantum dots (Part VII) and magnetic nanoparticles (Part VIII). As in the past, those patent documents cited in the article are summarized in a table at the end.
Recently, Draper announced a three-year agreement with Pfizer. This collaboration focuses on developing effective disease models for testing potential drug candidates based on microphysiological systems, also known as “organs-on-a-chip”.
The organs-on-a-chip technology is a three-dimensional microfluidic based multi-cell co-culture system that models the physiological, mechanical, and molecular environment of the human body and mimics the physiological functions of human organs. This technology offers unique in vitro disease models for new drug screening and toxicology testing. This technology has attracted attentions not only from academic institutes but also from the pharmaceutical industry. One of the main reasons for this interest is the potential cost and time savings for drug research and the development process. As required by the FDA drug approval process, new drug chemical entities are tested in animals before going into human Phase I testing for the drug approval process. The preclinical animal testing process is tedious and extremely expensive. Additionally, animal models are not always predictive for characterizing drug safety in humans. About 40% of drug compounds fail in Phase I clinical trials (Clinical Development Success Rates 2006-2015, BIO Industry Analysis, June 2016). To address these challenges, organs-on-a-chip has been proposed as a novel method to develop human disease models and replace preclinical animal testing.
We have briefly reviewed the research development and IP landscape in organs-on-a-chip. Here we would like to focus on the entrepreneurial developments in this field. As in the past, those patent documents cited in the article are summarized in the table at the end.
AxoSim is a New Orleans based startup launched in 2014. Its main pipeline is a Nerve-On-A-Chip, which is a 3D cell-based model mimicking living nerve tissue. It aims at preclinical prediction of neurological safety and efficacy in the early stages of drug development. This technology was developed from Dr. Michael J. Moore’s group at Tulane University (US 20150112244).
The Charles Stark Draper Laboratory is an American not-for-profit research and development organization, having a long history from 1932. In 2009, Draper initiated a new area of medical systems. Draper closely collaborated with scientists at MIT to develop microphysiological systems to emulate human organs and create disease models. At the end of 2016, Draper announced a 3-year agreement with Pfizer, using the “organs-on-a-chip” technology to facilitate pre-clinical drug development with a focus on personalized medicine. Currently Draper has built three microphysiological systems for modeling liver, vasculature and gastrointestinal organs (US 7,670,797, US 8,951,302, US 9,067,179, US 9,528,082).
Emulate Bio is a Wyss Institute spin-off company launched in 2014. It focuses on developing multiple organ-on-a-chip systems to model human physiological systems. The technology is based on discoveries in Dr. Donald Ingber’s lab, using models of the lung, liver, intestine, skin and brain (US 8,647,861). This lab is also interested in other organ systems such as the kidney and heart. In 2015, Emulate collaborated with Johnson & Johnson and Merck using organs-on-a-chip for drug discovery and development processes. In 2016, Emulate announced a collaboration with Seres Therapeutics to investigate Novel Microbiome Therapeutics for inflammatory Bowel Disease.
Hepregen is a MIT spin-off company founded in 2007, based on a technique developed in Dr. Sangeeta Bhatia’s lab (US 6,133,030). Its main product, HepetoPac Assay, utilizes a micropatterned hepatocyte co-culture system to model the metabolic activities of a liver system and was released in 2013. Their other pipeline product is HepetoMune, targeting an inflamed human liver model.
HμREL is a Merck supported company, which was incubated in New Jersey from 2007-2011. Its technology originated from Dr. Michael Shuler’s group at Cornell University (US 7,288,405 and US 8,748,180). In 2013, HμREL launched three liver-on-a-chip products for human, rat and dog. HμREL has also established a collaboration with Sanofi for pre-clinic drug development.
InSphero is a Swiss company founded in 2009. They use a scaffold-free 3D cell culture technique to generate self-assembled microtissues, emulating human organ systems (US 9,267,103 and WO/2017/001680). Their current pipelines include liver, pancreas, tumor, and skin microtissue systems and in vitro toxicology and drug discovery services.
Nortis is a Seattle based company, spun out of the University of Washington in 2012. Nortis developed a microfluidic kidney-on-a-chip for drug testing and launched its commercial product on 2015 (US 7,622,298 and US 20150240194A1).
Tara Biosystems is a New York-based Columbia University spin out company founded in 2014. Their focus is on developing a “heart-on-a-chip” system. The technology is based on research from Dr. Gordana Vunjak-Novakovic’s group at Columbia University and Dr. Milica Radisic’s group at Toronto University (US 20170002330A1 and US 20160282338). Tara Biosystems uses a Biowire platform, to introduce electrical stimulation on a microchip to stimulate stem cells to mature into heart tissue. This microtissue mimics adult heart muscles, offering a platform for drug discovery, cardiac toxicology, and personalized cardiology.
TissUse is a Berlin, Germany-based company developing a “Multi-Organ-Chip” platform based on technology discovered in Dr. Roland Lauster’s lab at Technische Universitat Berlin (US 20130295598). This company uses a multi-organ-chip as a platform to emulate human metabolic activities and accelerate the development of pharmaceutical, chemical, cosmetic, and personalized medical products. Currently, TissUse has announced their 2-Organ-Chip and 4-Organ-Chip products, involving simultaneously culturing from 2 to 4 different organ equivalents on a single chip connected to each other by perfusion channels or vasculature. Their next goal is to develop a human-on-a-chip system, with a larger number of organs cocultured on a single chip.
