Key clinical point: Q-122, a novel nonhormonal oral treatment, significantly improved vasomotor symptoms and was well-tolerated in women with breast cancer (BC) who received oral adjuvant endocrine therapy (ET).
Major finding: After 28 days, Q-122 led to a significantly higher improvement in the mean Vasomotor Symptom Severity Score of moderate and severe hot flushes and night sweats than placebo (−39% vs −26%; P = .018). Q-122 was well tolerated, and most adverse events were mild-to-moderate in severity.
Study details : Findings are from a multicenter, phase 2 study including 131 women with BC who were receiving oral adjuvant ET and were randomly assigned to receive 100 mg oral Q-122 or identical placebo, twice daily for 28 days.
Disclosures: This study was funded by QUE Oncology. The authors declared delivering lectures or receiving honoraria, grant funding, or personal fees from several sources. Two authors declared being current or former employees of QUE Oncology.
