Flibanserin for Low Libido in Breast Cancer Survivors
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether women can safely take both Flibanserin (a medication for low sexual desire) and tamoxifen to determine if Flibanserin alleviates low sexual desire. It targets women who have had breast cancer, completed their main treatment, and are currently on tamoxifen or similar medications. A suitable candidate for this trial is a woman who had breast cancer, shows no current signs of cancer, has been taking tamoxifen for at least three months, and experiences a noticeable drop in sexual desire causing distress. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to significant findings.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you must continue taking tamoxifen, an AI, or ovarian suppression. You cannot participate if you are on certain medications like strong or moderate CYP3A4 inhibitors.
Is there any evidence suggesting that Flibanserin is likely to be safe for women taking tamoxifen?
Research shows that flibanserin, a drug for low sexual desire, has some known side effects. It can cause fatigue, trouble sleeping, and dry mouth. It might also induce sleepiness or dizziness, so caution is advised when driving or engaging in activities requiring full attention.
Another study found that flibanserin was generally safe and well-tolerated by women with low sexual desire over a long period. This study, which lasted 52 weeks, reported improvements in sexual function for many participants.
While flibanserin is approved for treating low sexual desire, it caused breast tumors in mice at high doses. This finding comes from research on mice, not humans, but remains important to consider.
Overall, flibanserin has some side effects but is considered safe for many women. Prospective trial participants should consider these findings and discuss them with their doctor.12345Why do researchers think this study treatment might be promising for HSDD?
Flibanserin is unique because it addresses hyposexual desire disorder (HSDD) in breast cancer survivors, a condition that often lacks targeted treatments. Unlike other options that might focus on hormonal changes or psychological support, Flibanserin works by modulating neurotransmitters in the brain, specifically targeting serotonin, dopamine, and norepinephrine levels. Researchers are excited about Flibanserin because it offers a non-hormonal approach, making it potentially safer for breast cancer survivors who are on hormone therapies like Tamoxifen or aromatase inhibitors. This novel mechanism could provide a much-needed solution for improving sexual desire without interfering with cancer treatments.
What evidence suggests that Flibanserin might be an effective treatment for hyposexual desire disorder in women taking tamoxifen?
Research has shown that flibanserin, the treatment under study in this trial, can help treat low sexual desire in women. In one study, women taking flibanserin reported a noticeable increase in sexual desire compared to those taking a placebo, which contains no active medicine. Another study found that premenopausal women using flibanserin experienced a better overall sexual experience. Specifically, the SNOWDROP trial demonstrated that postmenopausal women had improved sexual desire and satisfaction with flibanserin compared to a placebo. Overall, these studies suggest that flibanserin may boost sexual desire in women with low sexual interest.26789
