Brief Summary:
Post-herpetic neuralgia (PHN) is pain following acute herpes zoster; defined as pain lasting longer than 3 months. Current first line management consists of tricyclic anti-depressants and anti-convulsants such as gabapentin and pregabalin. There is an unmet medical need for treatments got topical therapies that demonstrate efficacy without serious side effects.

Condition or disease Intervention/treatment Phase
Treatment of PHN Drug: 3VM1001 Other: Placebo Early Phase 1

Detailed Description:

Post-herpetic neuralgia (PHN) is defined as pain following acute herpes zoster (AHZ) lasting >3 months. PHN develops in about 10% of patients following an episode of AHZ. 95% of adults ate seropositive for varicella zoster virus antibodies, and are, therefore, at risk for AHZ and PHN. Wider use of AHZ vaccine approved in 2006 may reduce the incidence of PHN. Nevertheless, PHN may be severe and frequently interferes with daily activities and with sleep.

First line management of PHN pain currently is tricyclic anti-depressants and anti-convulsants such as gabapentin and pregabalin, and use of a 5% lidocaine patch. second line therapies include opioid analgesia and topical capsaicin: combinations of topical and systemic therapies may be used as well. These therapies have common side effects of dry mouth, constipation, sedation, urinary retention, nausea, somnolence, dizziness, weight gain and peripheral edema.

there is an unmet medial need for topical therapies that demonstrate efficacy without the significant side effects o the therapies mentioned above. 3VM cream, a low concentration of copper in a cream vehicle may b such a therapy.

Drug: 3VM1001
Self treatment 3 times daily for 10 days

Placebo Comparator: Placebo

Primary Outcome Measures :
  1. The time averaged mean in a standard 100 mm visual analog scale (VAS). [ Time Frame: 25 days total ]
    The time averaged mean of all patient pain scores over each study period; trend over time for each treatment sill be assessed by day of therapy to evaluate any increase or decrease in effect for each study treatment.


Secondary Outcome Measures :
  1. Adverse Events, serious adverse events, and study discontinuation [ Time Frame: 25 days total ]
    Collection of adverse events and the number of subjects discontinuing he study

  2. Patient Global Expression of change Scale (PGIC) from baseline (day 0) to the end of each study period. [ Time Frame: 25 days total ]
    This measure is a single-item rating by participants of their improvement with treatment on a 7-point sale that ranges from "very much improved" to very much worse" with "no change "the mid-midpoint".

  3. Change in Patient Global Assessment of Treatment Satisfaction from baseline to the end of each study phase. [ Time Frame: 25 days total ]
    Patient Global Assessment of Treatment Satisfaction from baseline to the end of each study phase. Patients will rate their overall satisfaction with study treatment using a 5-point categorical scale.

  4. Use of Rescue medication [ Time Frame: 25 days total ]
    recording of the use of rescue mediation at each phase of the study.

Criteria

Inclusion Criteria:

  • Diagnosis of PHN for >3 months;
  • Persistent pain for more than 6 months from appearance of herpes zoster rash that is not located above the scalp hairline, or in immediate proximity to mucous membranes (given the low toxicity of copper, PHN affecting the face and neck will be included, but subjects will be trained on avoidance of contact with the eyes or mouth);
  • Age 18 years or older;
  • Males or females of non-childbearing potential (i.e., 12 months or more of spontaneous amenorrhea, bilateral oophorectomy at least 6 months prior to randomization, hysterectomy with bilateral oophorectomy at least 6 months prior to randomization, or for females over 50 years of age, hysterectomy without bilateral oophorectomy at least 6 months prior to randomization); female subjects of childbearing potential must agree to use contraception (abstinence, birth control pills, rings or patches, diaphragm and spermicide, intrauterine device, condom and vaginal spermicide, surgical sterilization, vasectomy, progestin implant or injection); female partners of childbearing potential of male subjects must agree to use contraception as defined above;
