CC-10004 For The Treatment Of Vulvodynia

Study Overview
=================
Brief Summary
-----------------
Vulvodynia is characterized by persistent vulvar pain, which often occurs upon touch or pressure. The cause of vulvodynia is unknown but is presumed to involve many factors. Some of these factors may include altered immune response, infections, altered vaginal acid-base balance, allergic reactions and psychosexual disorders. Women are generally treated with medications such as anti-histamines, anti-depressants and anti-inflammatories, or with physical therapy to minimize symptoms. Other therapies for vulvodynia include topical agents (lidocaine, or compounded medications such as baclofen, gabapentin and amitriptyline), oral medications (gabapentin, pregabalin, calcium citrate), complementary therapies (yoga, guided imagery, cognitive behavioral therapy) or a low-oxalate diet, but these are often ineffective. Surgery for vulvodynia may be helpful in the hard to manage cases, but is utilized as a last resort.

Detailed Description
-----------------
CC-10004 is a well-tolerated, selective PDE4 inhibitor with a demonstrated inhibitory effect on inflammatory mediators and is under development for the treatment of inflammatory and immune mediated conditions. This is an open-label, one arm, phase II study at William Beaumont Hospital. Twenty female subjects aged 18 or older meeting criteria for diagnosis of vulvodynia or vulvar vestibulitis (vestibulodynia) will be treated with CC-10004 at 20mg orally twice a day for 12 weeks.The patient will be seen for a total of ten visits by the study coordinator.

Infections that occurred > 3 years prior to entry must have been effectively treated. Positive TB skin test (Mantoux test) History of incompletely treated latent Mycobacterium tuberculosis infection as indicated by a positive positive Purified Protein Derivative [PPD] skin test or in vitro test [T-SPOT®. TB, QuantiFERON Gold®] or chest x-ray. Clinically significant abnormality on the chest x-ray (CXR) at screening. Use of any investigational medication within 28 days prior to randomization or 5 half-lives if known (whichever is longer) Any clinically significant abnormality on 12-lead ECG at screening Positive human immunodeficiency virus (HIV), hepatitis B, or hepatitis C laboratory test result indicating active infection at screening.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Global Response Assessment | The primary efficacy measure was a Global Response Assessment (GRA), a subject completed questionnaire that measures improvement in overall symptoms. The GRA is a 7-point scale the allows the subject to respond to the question: As compared to when you started the study, overall how do you feel? The responses are: Markedly Improved - 7, Moderately Improved - 6, Mildly Improved - 5, Same - 4, Mildly Worse - 3, Moderately Worse - 2, Markedly Worse - 1. The primary outcome showing response to treatment was the number of subjects that were moderately or markedly improved on the GRA scale. | 12 weeks |
