Guilford Receives Patent for Compounds that Promote Nerve Growth BALTIMORE, March 27 /PRNewswire/ via Individual Inc. -- Guilford Pharmaceuticals Inc. (Nasdaq: GLFD) today announced that the company has been issued U.S. Patent No. 5,614,547 from the U.S. Patent and Trademark Office relating to the compositions and uses of a series of compounds that promote nerve growth and repair for the treatment of neurodegenerative disorders. These compounds are neuroimmunophilin ligands, which are orally-active and cross the blood-brain-barrier in animal models. The results of some of Guilford's work in this field with GPI-1046, which is covered by the patent, were published earlier this month in the Proceedings of the National Academy of Sciences (U.S.A.), Volume 94, Number 5, pp. 2019-2024, 1997. "We are very pleased to announce the issuance of our first U.S. patent in our neuroimmunophilin program. To date, we have filed numerous U.S. and foreign patent applications relating to neuroimmunophilin compounds and their uses. Guilford scientists, utilizing structure-based drug design and combinatorial chemistry techniques, have synthesized hundreds of small molecule neuroimmunophilin ligands in several distinct chemical series, which possess the ability to cause nerves to grow or regenerate in animals. We are actively investigating our neuroimmunophilin ligands in animal models of a variety of chronic and acute neurodegenerative disorders, such as Parkinson's Disease, Alzheimer's Disease, multiple sclerosis, traumatic spinal cord injuries, peripheral neuropathies, and stroke," commented Dr. Craig R. Smith, President and C.E.0. of Guilford. Guilford Pharmaceuticals Inc. is a biopharmaceutical company engaged in the development of polymer-based therapeutics for cancer, and novel products for the diagnosis and treatment of neurological diseases, including Parkinson's disease, Alzheimer's disease, stroke, severe head trauma, spinal cord injuries, multiple sclerosis, peripheral neuropathies, and cocaine addiction. This press release contains forward-looking statements that involve risk and uncertainties, including those described in the Company's Form S-3 (SEC Registration No. 333-23001), that could cause the Company's actual results and experience to differ materially from anticipated results and expectations expressed in these forward-looking statements. In particular, pre-clinical results are based on a limited number of animal models, and there can be no assurance that the Company will be able to successfully develop one or more of its compounds into safe and effective FDA-cleared drugs. While the Company has filed numerous patent applications claiming neuroimmunophilin ligands for neurotrophic applications in the U.S. and abroad, the patentability, validity, priority, enforceability, and non-infringement of claims made in such applications cannot be assured.
