Trial Summary

What is the purpose of this trial?

This phase II trial tests whether fisetin works to improve physical function in women who have received chemotherapy for stage I-III breast cancer treatment. Fisetin is a naturally occurring substance that is found in strawberries and other foods. Fisetin eliminates cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release harmful substances that causes inflammation and damages nearby healthy cells. Studies have shown that chemotherapy causes a build-up of these senescent cells. Giving fisetin may eliminate senescent cells and improve physical function in postmenopausal women who have received chemotherapy for breast cancer.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you must stop all current medications. However, you cannot take certain medications with senolytic properties like curcumin or St. John's wort during the trial. Some medications may need to be withheld temporarily during dosing intervals. It's best to discuss your specific medications with the trial team.

What data supports the idea that Fisetin for Breast Cancer Survivors is an effective treatment?

The available research shows that Fisetin can be effective in treating breast cancer, particularly triple-negative breast cancer (TNBC), which is a challenging type to treat. Fisetin was found to stop the growth of TNBC cells and even helped other cancer drugs work better. It also reduced the spread of cancer cells and helped reverse changes in the cells that make them more aggressive. In studies with mice, Fisetin reduced the size of breast tumors and prevented them from spreading to the lungs. These findings suggest that Fisetin could be a promising option for managing breast cancer. ^{1 2 3 4 5}

What safety data exists for fisetin as a treatment?

The available research on fisetin, a naturally occurring flavonoid, primarily focuses on its anticancer properties and effects on cancer cells, including breast cancer. Studies have shown that fisetin can induce apoptosis and inhibit cell growth in various breast cancer cell lines without significantly affecting non-malignant cells. It has been observed to enhance the effects of certain chemotherapeutic drugs and has potential as an anticancer agent. However, the research does not provide specific safety data or information on adverse effects in humans, indicating a need for further investigation to assess its safety profile in clinical settings. ^{1 4 6 7 8}

Is fisetin a promising drug for breast cancer survivors?

Yes, fisetin shows promise as a drug for breast cancer survivors. It has been found to stop the growth of cancer cells and even help other cancer drugs work better. Fisetin is a natural compound found in fruits and vegetables, and it has been shown to have strong effects against cancer cells, including those in breast cancer. It can help reduce the spread of cancer and may be a cost-effective option for treatment. ^{1 2 4 9 10}

Treatment Details

Interventions

• Fisetin

Trial Overview The TROFFi trial is testing fisetin, a substance found in strawberries that might remove aging cells built up from chemotherapy, which could improve physical function. Women will either receive fisetin or a placebo while also undergoing quality-of-life assessments through questionnaires and biospecimen collection.

Participant Groups

Group I: Arm A (fisetin) Experimental Treatment 4 Interventions

Patients receive fisetin PO on days 1, 2, and 3. Treatment repeats every 2 weeks for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples throughout the trial.

Group II: Arm B (placebo) Placebo Group 4 Interventions

Patients receive placebo PO on the trial. on days 1, 2, and 3. Treatment repeats every 2 weeks for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo collection of blood samples throughout the trial.

Findings from Research

Fisetin effectively inhibited the growth of triple-negative breast cancer (TNBC) cells, specifically MDA-MB-468 and MDA-MB-231, while sparing non-malignant cells, indicating its potential as a targeted treatment option.

The mechanism of action involves inducing apoptosis in TNBC cells through mitochondrial membrane permeabilization and activation of caspases, along with inhibition of Aurora B kinase, suggesting that fisetin could enhance the effectiveness of existing chemotherapy agents like cisplatin and 5-fluorouracil.
