Convergence Pharmaceuticals Limited (“Convergenceâ€), the company focused on the development of novel and high value analgesic medicines for the treatment of chronic pain, today announces that it has started a Phase II proof of concept study with CNV2197944 in pain associated with post-herpetic neuralgia (PHN). Convergence is conducting the development of CNV2197944 on behalf of Calchan Ltd.
The trial is a randomised double-blind, placebo controlled, phase II study to evaluate the efficacy and safety of orally administered CNV2197944 in patients with PHN. The primary endpoint of the trial is the effect of repeat oral dosing of CNV2197944 on the pain experienced in PHN, as measured by the Pain Intensity Numeric Rating Scale (PI-NRS), after three weeks, compared to baseline. The study is expected to conclude in 1Q2014.
Post-herpetic neuralgia (PHN) is a nerve pain due to damage caused by the varicella zoster virus (Shingles or Chicken Pox). Typically, the neuralgia is confined to a dermatomic area of the skin and follows an outbreak of the virus in the same dermatomic area. Injury to sensory nerves can cause excruciating pain, sometimes persisting for months or years.
