Cyprium Therapeutics, Inc.

Cyprium Therapeutics, Inc. (Cyprium), a Fortress Biotech company, is focused on the development of novel therapies for the treatment of Menkes disease and related copper metabolism disorders. In March 2017, Cyprium entered into a Cooperative Research and Development Agreement (CRADA) with the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), part of the National Institutes of Health (NIH), to advance the clinical development of Phase 3 candidate CUTX-101 (Copper Histidinate injection) for the treatment of Menkes disease. In addition, Cyprium and NICHD entered into a worldwide, exclusive license agreement to develop and commercialize adeno-associated virus (AAV)-based gene therapy, called AAV-ATP7A, to deliver working copies of the copper transporter that is defective in Menkes patients, and to be used in combination with CUTX-101. Both CUTX-101 and AAV-ATP7A gene therapy were granted orphan drug designation by the FDA.

Menkes disease is a rare X-linked pediatric disease caused by gene mutations of copper transporter ATP7A, which affects approximately one in 100,000 newborns per year. Biochemically, Menkes patients may have low levels of copper in their blood and brain, as well as abnormal levels of catecholamine, but definitive diagnosis is typically made by sequencing of the ATP7A gene. The condition is characterized by distinctive clinical features, including sparse and depigmented hair (“kinky hair”), failure to thrive, connective tissue disorders and severe neurological symptoms such as seizures. Mortality is high, with many patients dying before the age of three. Milder versions of ATP7A mutations are associated with other diseases, including Occipital Horn Syndrome and ATP7A-related Distal Motor Neuropathy. Currently, there is no FDA-approved treatment for Menkes disease and its variants. For more information, please visit www.cypriumtx.com
