What this trial studies

This clinical trial investigates the potential benefits of Coenzyme Q10 in reducing the toxicity associated with paclitaxel chemotherapy in women with newly diagnosed breast cancer. Forty female participants will be randomly assigned to either a control group receiving standard chemotherapy or a treatment group receiving chemotherapy along with Coenzyme Q10. The study will monitor various side effects of chemotherapy, including fatigue, nausea, and neuropathy, as well as assess the overall quality of life of the participants. Ethical approval has been obtained, and all participants will provide informed consent before enrollment.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with newly diagnosed breast cancer who have not yet undergone chemotherapy.

Not a fit: Patients with advanced liver disease, chronic kidney disease, or those with a history of allergy to Coenzyme Q10 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help alleviate the side effects of chemotherapy, improving the quality of life for breast cancer patients.

How similar studies have performed: While the use of Coenzyme Q10 has been explored in various contexts, this specific approach to mitigate chemotherapy toxicity in breast cancer patients is relatively novel.
