A new drug to manage resistant chronic pain

BL-7050 is a new chemical entity based on the molecular structure of diclofenac (Voltaren), a well-known non-steroidal anti-inflammatory drug (NSAID) widely used in the treatment of nociceptive and inflammatory pain. However, BL-7050 operates via a novel mechanism of action, namely opening specific potassium channels in nerve cells. The opening of these channels reduces the activity of the nerve cells, thereby reducing or preventing pain signals.

Neuropathic pain is a complex, chronic state of pain that results from dysfunctional or injured nerve fibers. Neuropathic pain is associated with various conditions, including shingles, diabetes and cancer and is reported to affect 1% to 3% of the population. Patients describe the symptoms as burning, stabbing, electric shock or itching sensations, which can cause extreme discomfort for extended periods of time. A variety of medications are used to treat neuropathic pain, including antidepressants and anti-seizure medicines. However, these medications have significant side effects and are not always effective.  

If this drug ultimately proves itself though all the phase clinical trials to be successful, Anaysts see it receiving possible Orphan drug status to be prescribed to patients suffering from extreme pain caused by such diseases as terminal late stage cancers and cystic fibrosis, for example.
