NIH Grant to Keystone Nano to Target Nanoparticles to Cancer Cells
KN is pleased to announce that it has been awarded a National Institute of Health (NIH) grant to further develop its nanoparticles for the treatment of cancer. The National Cancer Institute, a part of the NIH, has awarded a grant to Keystone Nano to further develop our siRNA nanoparticle technology.
Most current chemotherapeutics have are not selective to cancer cells and have dose-limiting toxicities that prevent optimal effects being obtained. Ribonucleic acid interference (RNAi) has the potential to be a safe, selective and personalized treatment approached for a variety of genetic-based diseases, including cancer. In particular, the design of small interfering RNA (siRNA) sequences to prevent the expression of cancer-fueling mutations provides a dramatic alternative to current therapeutic approaches. However, an effective delivery vehicle is required for systemic RNAi therapy to protect siRNA during circulation, concentrate siRNA at tumor sites and mediate cellular uptake as well as endosomal escape. This NIH funded project is designed to optimize a novel, combinatorial RNAi treatment for advanced breast cancer based on delivery by calcium phosphate nanoparticles, called NanoJackets. Building on the demonstrated in vivo efficacy of Keystone Nano’s siRNA NanoJackets, an active targeting ligand will be added and evaluated for improved biodistribution, cellular uptake and in vivo efficacy of siRNA NanoJackets for breast cancer therapy. If successful, the development of this targeted, combinatorial RNAi nano-therapeutic will provide a novel option for the personalized treatment of breast cancers that fail to respond to current therapies.
The project will be led by Dr. Mylisa Parette, Research Manager at Keystone Nano and Dr. Carly Carter, Research Team Leader at Keystone Nano. The project is supported by the company’s Chief Science Officer, Dr. James Adair, Chief Medical Officer, Dr. Mark Kester, and CEO, Mr. Jeff Davidson.
Based in State College, Keystone Nano is working at the interface between nanotechnology and the life sciences and has licensed intellectual property around nanoparticles from Penn State University. The company is working to commercialize NanoJacket products and Nanoliposomes for a variety of medical applications.

NanoJackets, which are stable, non-toxic particles, contain be loaded with small “interfering” ribonucleic acids (siRNA) that effectively deliver RNA to select cancer-causing mutated cells. NanoJackets effectively target and concentrate just at the tumor site, significantly diminishing the side effects for the patient. The goal of this project is to develop new therapies for cancer by preparing an Investigational New Drug (IND) application to the FDA for a novel product for the treatment of advanced cancers. Keystone Nano has been developing NanoJacket technology for the past six years.
Jeff Davidson, CEO of Keystone Nano, commented, “The American Cancer Society estimates that over 1.6 million patients will be diagnosed with cancer in 2012 and over 575,000 will die of the disease this year. Improving the effectiveness of cancer therapies by employing the use of nanotechnology can save lives and improve the patient’s quality of life both during and after therapy. We are seeking to move this promising technology promptly from the research bench to the clinic, and we appreciate the support of the Department of Health.”
Keystone Nano originally developed siRNA NanoJackets under a Phase I NCI SBIR contract and is currently optimizing formulations for preclinical testing. The company has also received significant support from Ben Franklin Technology Partners of Central and Northern Pennsylvania, the Pennsylvania Nanomaterials Commercialization Center, the Nanotechnology Institute, and from select corporate partners.
The project will be led by principal investigator Dr. Mark Kester, Passananti Professor of Pharmacology at the Penn State College of Medicine as well as Chief Medical Officer at Keystone Nano, Dr. Mylisa Parette, Research Manager at Keystone Nano and Dr. James Adair, Professor of Materials Science and Engineering at Penn State University as well as Chief Science Officer of Keystone Nano.

Keystone Nano Awarded a SBIR Contract from the National Cancer Institute
The National Cancer Institute (NCI) an Institute of the National Institutes of Health has awarded a Small Business Innovation Research (SBIR) contract to Keystone Nano to develop nanoparticles containing both diagnostic and therapeutic compounds to enhance the treatment of cancer. This is the second SBIR award from the NCI to support the development of Keystone Nano’s NanoJacket technology.
NanoJackets are small (30nm), colloidally stable, bioresorbable and can encapsulate various chemical compounds inside the nanoparticle. Keystone Nano has encapsulated a variety of compounds, including fluorescent molecules and chemotherapeutic drugs, within NanoJackets. Biological testing of prototypes indicates that NanoJackets both protect and enhance the effectiveness of encapsulated compounds by delivering them directly to desired locations, such as tumor sites. The nanoparticles developed with this contract will contain an imaging agent as well as a therapeutic compound. The encapsulation of both compounds within each NanoJacket will allow the simultaneous imaging and treatment of tumors, giving physicians the ability to monitor the effectiveness of the treatment in real time.
Jeff Davidson, CEO of Keystone Nano notes “Keystone Nano looks forward to further developing the diagnostic and therapeutic applications of NanoJackets with the support of the NCI”.
The American Cancer Society estimates that over 1.5 million patients will be diagnosed with cancer in 2010 and over 550,000 will die of the disease this year. Improving the effectiveness of cancer therapies by employing sensible nanotechnology can save lives and improve the patient’s quality of life both during and after therapy.
Dr. Mylisa Parette, author of the grant and principal investigator, will lead the research and development efforts associated with this project, supported by KN’s development team in State College and Hershey.

Keystone Nano Named International Winner of The Second Annual International Nanotechnology Business Idea Competition
Company is developing Molecular Dots for Improved Disease Imaging and Drug Delivery
CLEVELAND, October 21, 2005 - Keystone Nano won the International Award of $75,000 in the second annual International and North Coast Nanotechnology Business Idea Competitions held on the campus of Case Western Reserve University. http://www.tiime.case.edu/nano/ A panel of judges featuring representatives of venture capital firms, corporations and nanotechnology researchers selected Keystone Nano as the International winner.
Keystone Nano is building its company around technology developed at Penn State University and at the Hershey Medical Center. "We'll leverage this award to speed the development of the company", said Jeff Davidson, chief executive officer of Keystone Nano. "The science is outstanding - as it allows the creation of trillions of distinct tiny drug containing Molecular Dots - now we want to build an outstanding business that uses these dots to improve human health."
"Winning the International Nanotechnology Business Idea Competition provides important validation for its technology and business team," said Mark Kester, chief medical officer for Keystone Nano. Dr. Kester is also a professor at the Penn State College of Medicine in Hershey, Pennsylvania. "We've got some momentum now and we're going to take advantage of it," Dr. Kester said.
The company has developed Molecular Dots that are 10 nanometers to 80 nanometers particles that can deliver either therapeutic drugs or imaging solutions inside a patient's body. The Molecular Dots are so tiny that they don't prompt a response from the body's immune system and can work more effectively than other internal drug delivery or imaging systems.
In the imaging area the company is working to use these MDs to more precisely image cancerous tumors earlier in the cancer development process. The goal of this early imaging is to identify cancers when they are smaller and before they have spread to other organs. Identifying cancer earlier helps improve treatment options. If Keystone Nano's imaging is successful it should result in fewer cancer deaths and more modest surgical or drug therapy interventions.
Keystone Nano's molecular dots are designed to improve the delivery of drugs that are not water soluble, or that have physical characteristics that make them difficult to deliver. These reluctant drugs can be dispatched in a miniaturized trucking force of 1,000 trillion Molecular Dots that will deliver the drugs to remote regions of the human body. The drugs delivered will improve drug therapy for patients being treated for a variety of cancers or cardiovascular diseases.
Organizers of the Nanotechnology competition include three Case Western Reserve University programs and NorTech's Nano-Network. Sponsors include ASM International, Nanofilm, Ferro Corp., Case, Forest City Enterprises, The Partnerships for Innovation Program of the National Science Foundation and the Joseph P. & Nancy F. Keithley Foundation.
Last year's top winner of the competition, QD Vision of Watertown, Mass., recently raised at least $6 million in venture capital in a venture round financed by Highland Capital Partners, North Bridge Venture Partners, and OI Ventures. Gary Wnek, co-director of TiME at Case Western Reserve University remarked "I wouldn't be surprised at all if a few of our finalists today are able to attract venture capital in the near future."
