Summary

The goal of this clinical trial is to compare 1% and 3% diclofenac gel (DARE-PDM1) to placebo in women with symptomatic primary dysmenorrhea. The main question it aims to answer are:

Is DARE-PDM1 1%, 3% diclofenac gel systemically safe? What are the systemic levels of DARE-PDM1 1%, 3% diclofenac gel in plasma and vaginal fluid following 1 dose and 3 doses.

Criteria

Inclusion Criteria:

• Females ages 18- 50 years old (inclusive)

• Agrees to use adequate non-hormonal birth control during the trial (e.g. study provided male condoms without nonoxynol-9 lubricant, tubal sterilization, heterosexual abstinence) (Because hormonal birth control is a known off label treatment for dysmenorrhea, if the participant is on hormonal birth control other than Depo-Provera contraceptive injection, she agrees to discontinue it and have at least one spontaneous intervening menses before the start of the study period. If using Depo Provera, has not had an injection within the 4 months before Visit 1 and must have had a spontaneous menses prior to visit 2.)

• Provides informed consent for participating in the trial

• Willingness to use only study-provided oral paracetamol as rescue pain medication for dysmenorrhea, if needed according to investigator's instruction.

• Patient is fluent in the English language.

• Patient is capable of understanding and complying with the protocol and agrees to sign the informed consent document.

• Patient has had a cervical screen performed within five years prior to Visit 1 and can provide documentation indicating normal test results consistent with Australian Health guidelines. If the patient cannot provide documentation, a cervical screen will be performed at Visit 1. Patients with abnormal findings will be excluded from study participation and be referred for follow-up medical care as appropriate.

Exclusion Criteria:

• Positive pregnancy test
