Eligibility
Key inclusion criteria
- Females ages 18- 50 years old (inclusive)

- Self-assessment of historic dysmenorrhea associated pain level of = 5 on a scale of 0
- 10 in at least one of the following anatomic sites: pelvic/vaginal pain, low back
pain, while not using NSAIDs or hormonal contraception.

- Non-pregnant status

- If applicable, agrees to be sexually abstinent and place nothing in the vagina during
the 120 hours between visits 3 and 8 and the 3-day period of the multiple dose
regimen.

- 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.

Key exclusion criteria

- Have a positive Sexually Transmitted Infection (STI) test at screening for Chlamydia
trachomatis or Neisseria gonorrhea

Summary
Brief 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.

Participants will be seen for routine safety evaluations and complete a daily diary recording
dysmenorrhea associated pain.
