Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
Change from baseline in the sum of daily numeric pain rating scale (NPRS) score at the end of each treatment period.
The participants assessed their current pain using the 11-point NPRS where: 0=no pain to 10=worst pain imaginable.
Daily for 8 days for each of 2 treatment periods, up to 1 month in total
Number of participants with an Adverse Event (AE).
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The number of participants with AE(s) in each period will be reported.
Daily for 8 days for each of 2 treatment periods, up to 1 month in total
Secondary Outcomes (6)
Change from baseline in average daily NPRS score, and the proportion of participants with at least 30% and 50% reductions
Daily for 8 days for each of 2 treatment periods, up to 1 month in total
Change from baseline in the short-form McGill Pain Questionnaire 2 (SF-MPQ-2)
Day 1 and Day 8 for each of 2 treatment periods, up to 1 month in total
Change from baseline in weekly sleep interference scores assessed with Pain and Sleep Questionnaire three-item index (PSQ-3)
Day 1 and Day 8 for each of 2 treatment periods, up to 1 month in total
Patient global impression of change (PGIC)
Day 8 for each of 2 treatment periods, up to 1 month in total
Frequency of use and dose of rescue medication during treatment period
Daily for each of 2 treatment periods, up to 1 month in total

Interventions
Each participant will have 2 treatment periods, separated by a washout of at least 7 days. Participants will be randomized 1:1 to receive VMD-3866 gel in one period, and placebo gel in the other. Before the start of each treatment period, participants will have a Run-in period lasting 7 days, during which they will record NPRS scores each morning in a trial diary. Participants will continue to record NPRS scores in the trial diary during treatment periods 1 and 2 (about 1 h after each dose). Participants will be screened within 45 days before their first treatment period. Eligible participants may attend an outpatient visit up to 14 days before their first dose of VMD-3866 or placebo, for baseline QST and, in ≥ 8 participants, a skin biopsy. Participants will visit the site for their first and last doses (Days 1 and 8) in each treatment period. All other doses they will self-administer at home.

Eligibility Criteria
You may qualify if:
- Male or female patient who has received any type of chemotherapy treatment for cancer and are in remission.
- Participants must be diagnosed with CIPN and must be showing moderate (Grade 2, as defined by the Common Terminology Criteria for Adverse Events) symptoms of peripheral sensory neuropathy, including pain and hypersensitivity, for ≥ 3 months. Participants must have had stable symptoms of CIPN for 8 weeks before screening. Participants with any other conditions associated with neuropathy, or conditions which might confound pain assessment (e.g. other severe pain or a skin condition in the area affected by neuropathy) will be excluded.
- Aged 18-80 years (inclusive) at the time of consent.
- Mean daily pain score of 4-8 on the 11-point NPRS, for at least 4 days during Run-in 1.
- A score of 0 or 1 on the ECOG Performance Status Scale.
- Capable of self-administering topical VMD-3866 or placebo gel to the designated treatment area(s).
- Capable of understanding the nature of the trial and any hazards of participating in it. Ability to communicate satisfactorily with the investigator and to participate in, and comply with the requirements of, the entire trial.
- Agrees to take only the allowed rescue medication (paracetamol) for breakthrough pain, from screening and throughout the study.
- Willing to give written consent to participate after reading the informed consent form, and after having the opportunity to discuss the trial with the investigator or their delegate.
