Safety/Efficacy of Q-122 in Breast Cancer Patients Taking Tamoxifen or Aromatase Inhibitor


Brief description of study

This is a Phase 2 proof-of-concept (POC) study designed to determine the effectiveness of Q-122 for the treatment of Vasomotor Symptoms (VMS) versus placebo. Participants who meet all eligibility criteria following the Screening/Run-In period will be randomized to 1 of 2 treatment arms; blinded Q-122 or placebo for a period of 28 days. All participants will be followed for a 2-week, drug-free, follow-up period after their last dose of blinded Q-122/placebo before termination from the study.

Detailed Study Description

Vasomotor symptoms (VMS) are significant in postmenopausal women with the most effective medications for relief being hormonal preparations. Non-hormonal medications have demonstrated efficacy but at a far lower level than estrogen replacement therapy. For women with a history of breast cancer, hormone replacement therapy is often contraindicated and is not an option for women receiving endocrine therapy including tamoxifen (TAM) and aromatase inhibitors (AI). Breast cancer survivors, and women receiving endocrine therapy in particular, have a high rate of problematic hot flashes. In an open label Phase 1 study of the safety and activity of Q-122 in breast cancer patients taking TAM or an AI, 8 of 9 women who received at least 1 dose of 100 mg and 10 of 11 women who received at least 1 dose of 200 mg had a reduction in hot flashes of 2 or more per day, the FDA criteria for anti-VMS activity. This study will define the effect of Q-122 versus placebo in a population of women with a history of or current breast cancer who have an average of 50 or more moderate to severe hot flashes per week.
