NCT ID: NCT02313545

Last Updated: 2018-03-14

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 50 participants

Brief Summary

In this open label study, 50 eligible women will be assigned to receive the investigational product (IZN-6NVS) - 2.5 g of cream/day for 14 days, followed by 3 applications per week for the next 4 weeks. Clinical assessment of the severity of vaginitis will be performed at baseline and after 2 and 6 weeks of treatment.

The study will evaluate safety, tolerability and efficacy of IZN-6NVS vaginal cream, in the treatment of atrophic vaginitis (AV) and desquamative inflammatory vaginitis (DIV).

Detailed Description

This will be a Phase IB study comprised of three study groups:

• Group 1: Women who are naturally or surgically menopausal and symptomatic for AV, but who decline treatment with topical or systemic estrogen.
• Group 2: Women rendered menopausal as a result of pharmacologic treatment (including, but not limited to, aromatase inhibitor treatment, selective estrogen receptor modifiers (SERMs), and GnRH analog treatment), who decline treatment with topical or systemic estrogen.
• Group 3: Pre-menopausal women diagnosed with DIV.

The study will evaluate safety, tolerability and efficacy of IZN-6NVS vaginal cream, in the treatment of atrophic vaginitis (AV) and desquamative inflammatory vaginitis (DIV).

20 eligible women of groups 1 and 2 and up to 10 eligible women of group 3 will be assigned to receive 2.5 g of cream/day for the first 14 days, followed by 3 applications per week for the next 4 weeks. Clinical assessment of the severity of vaginitis will be performed at baseline and after 2 and 6 weeks of treatment, which will be the end of the study. Patient reported symptom severity will be assessed by questionnaire at baseline and after 2 and 6 weeks of treatment, and at follow-up.
