Analgesic Efficacy and Safety of Topical VMD-3866 Gel in Management of Pain Induced by Chemotherapy (CIPN)

Peripheral neuropathy is a disorder caused by damage to the peripheral nerves. Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of certain chemotherapy drugs, such as platinum-based compounds, taxanes, and vinca alkaloids, which can damage nerve fibres by disrupting their structure and function. At present, relief of neuropathic pain in CIPN is limited, and existing therapies providing only modest and variable efficacy across patients. This is a study of VMD-3866 gel (the study medicine which is non-opioid, non-NSAID), an experimental new topical medicine for treating pain caused by CIPN. The goal of this study is to assess if the study medicine improves pain symptoms in patients with CIPN, and to find out the side effects of the study medicine if any. The study medicine will work by selectively blocking a specific sub-type of proteins (called T-type calcium channels) in the nerves under the skin which will lower the activity of the nerves and therefore reduce pain. It is a topical gel, meaning that it is applied to the skin, and its novel gel formulation limits that only little amount of study medicine may enter the blood and none enters the brain. This means it's unlikely to be addictive and it's unlikely to have any impact on participant current medications. Researchers will compare study medicine to a matching placebo (a look-alike gel that contains no drug) to see if VMD-3866 gel works to management of pain caused by CIPN.
