Fezolinetant for Hot Flashes
(FLASH-CV: Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether the drug fezolinetant can improve blood vessel health in women experiencing moderate to severe hot flashes. The study will compare fezolinetant to a placebo (a pill with no active drug) over 12 weeks. It seeks women who are peri- or post-menopausal and have health issues such as obesity, high blood pressure, or high blood sugar. Women whose frequent hot flashes affect daily life and who have these health concerns might be a good fit. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop your current medications, but you cannot participate if you are using strong or moderate cytochrome P450 1A2 inhibitors. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that fezolinetant is likely to be safe for humans?
Research shows that fezolinetant is generally easy for patients to handle. Studies have found that it effectively reduces moderate to severe hot flashes, with few side effects reported. In one study, patients taking fezolinetant experienced fewer hot flashes without any major safety issues. Another study found it to be well-tolerated over six months, with no serious side effects. Overall, evidence suggests that fezolinetant is safe for treating hot flashes, with most patients managing it well.12345
Why do researchers think this study treatment might be promising?
Unlike the standard treatments for hot flashes, which often include hormone replacement therapy, Fezolinetant offers a non-hormonal alternative. Researchers are excited because Fezolinetant works by blocking the neurokinin B receptor, a key player in regulating body temperature. This novel approach could provide relief without the hormonal side effects associated with current therapies, offering a safer option for many women.
What evidence suggests that fezolinetant might be an effective treatment for hot flashes?
Research has shown that fezolinetant, which participants in this trial may receive, reduces the frequency and severity of hot flashes in women. Studies found that women taking fezolinetant experienced fewer and less intense hot flashes within 4 to 12 weeks compared to those on a placebo. Additionally, fezolinetant appears to improve sleep and work performance in daily life. These findings suggest it could be a promising option for women with moderate to severe hot flashes.35678
