Allon Therapeutics, Inc. announced that it has been granted a U.S. patent that covers the use of the company's neuroprotective technology platform in the treatment of peripheral neuropathy. This includes the company's lead drug candidate, davunetide, and pipeline product AL-309 as treatments for peripheral neuropathy caused by anti-cancer drugs. The company previously presented preclinical data at a Society for Neurosciences meeting that showed the activity of AL-309 in chemotherapy-induced neuropathy. AL-309, administered in combination with oxaliplatin (an anti-cancer agent) reduced pain symptoms in a model of peripheral neuropathy. Peripheral neuropathy and neuropathic pain can result from a variety of medical conditions, such as diabetes; or from the side-effects of drug treatments, such as cancer chemotherapy. Peripheral neuropathy is caused by damage to peripheral nerves that detect touch and painful stimuli. Symptoms include tingling, hypersensitivity to light touch or painful stimuli and chronic pain. These sensory problems can also proceed to numbness and loss of sensitivity.
