DOYLESTOWN, Pa., Dec. 8 /PRNewswire-FirstCall/ -- The Quigley Corporation announced today that its wholly owned subsidiary Quigley Pharma’s naturally derived compound QR-336 once again has shown to protect mice when exposed to a lethal dose of ionizing radiation. An in-vivo study involving pre-treating mice with QR-336, followed by lethally irradiating the treated and untreated groups has shown a four-fold increase (80% survival rate) in mice surviving the otherwise lethal dose of radiation as compared to the non-treated group.
Results also show that bone marrow extracted from animals that were previously treated with QR-336 and irradiated, could protect another set of irradiated animals whereas bone marrow also extracted from untreated, irradiated mice could not protect lethally irradiated animals.
“These promising results, which further build upon previous in-vivo and in-vitro work, suggest the usefulness of QR-336 as a radioprotective agent,” said Dr. Richard Rosenbloom, Quigley Pharma’s Chief Operations Officer. “The implications of these findings are timely. Ionizing radiation even from cosmic sources could effect astronauts and commercial airline flight crews and has been linked to Leukemia and other pathology. The development of a naturally derived non-toxic drug could potentially offer some protection against these effects.”
QR-336 was studied in a series of in vitro cellular and in vivo mouse radiation experiments by Professor Yakov Ron, Department of Molecular Genetics and Microbiology and Immunology at the University of Medicine and Dentistry of New Jersey (Robert Wood Johnson Medical School).
The test animals were exposed to 9 Gys of Gamma irradiation. Acute radiation poisoning of 4.5 Gys would be fatal to half the exposed human population. The protective effect of QR-336 from gamma irradiation was assessed by the ability of bone marrow (BM) cells to reconstitute lethally irradiated mice. These experiments provide a strong indication that QR-336 may protect BM stem cells from irradiation induced cell death. The results of this study further confirm the results of previous mouse experiments of this compound.
“Results also show that QR-336 may provide a benefit for national security, the nation and the public at large,” added Dr. Rosenbloom.
Quigley Pharma has previously met with the FDA Division of Counterterrorism, as well as the Division of Medical Imaging and Radiopharmaceutical Drug Products (DMIRDP) in pre-IND stages. Based on discussions with the FDA, and these newly encouraging results, Quigley Pharma is moving forward on the next steps towards an IND for QR-336 as a protective agent against radiation exposure.
The NIH has been tasked by DHHS to develop a strategic plan and research agenda to guide the development of medical countermeasures against possible terrorist attacks. In June 2005, the NIH issued a Strategic Plan (NIH Pub. No. 05-5608), which addresses the lack of protective and therapeutic medical treatments for radiation exposure. There are several minimally effective therapeutic agents available, such as those providing decorporation effects. These decorporation drugs aid in the binding and removal of the radionuclides, following the exposure to radioactive sources, where damage to the body has already begun. The properties of QR-336 may indicate the protective treatment category, which may show a protective effect prior to being exposed to the radioactive source, offering a greater chance of survival and protective effect.
Quigley Pharma plans to pursue the development program and work with the necessary government institutions in order to further test the effectiveness of QR-336.
