Brief summary
This research study hopes to examine the effects of Coenzyme Q10 on doxorubicin (Adriamycin) metabolism during breast cancer treatment.
Detailed description
Doxorubicin is a lifesaving breast cancer treatment. However, approximately 3-20% of women who receive doxorubicin treatment experience some damage to their heart muscle. Coenzyme Q10 is a fat soluble antioxidant dietary supplement that may protect against this heart damage during doxorubicin treatment. It is unknown how Coenzyme Q10 may interact with doxorubicin. This study will assess the effects of Coenzyme Q10 on doxorubicin metabolism. This is a phase I randomized, placebo-controlled, cross-over pharmacokinetic and dose-finding study to assess the safety of CoQ10 during doxorubicin treatment for breast cancer. Safety will be assessed by measuring 1) intra-patient differences in doxorubicin and its active metabolites, with and without CoQ10, and 2) adverse events. The investigator hypothesizes that CoQ10 administration during doxorubicin treatment is safe and will not affect doxorubicin active metabolites. Using three dose levels of CoQ10, the maximum tolerated dose (MTD) will be determined by assessing change in doxorubicin concentration (area under the curve (AUC), change in peak concentration levels (Cmax)), and adverse events.

Exclusion criteria
* Inability to understand or an unwillingness to sign a written informed consent document; * Any significant toxic side effects related to first or second dose of doxorubicin/cyclophosphamide chemotherapy or biologic therapy that did not resolve to less than a CTCAE 3.0 grade 3 non-hematological toxicity; * Currently using any investigational agent; * Unstable or severe intercurrent medical condition that, in the opinion of the investigator, might interfere with the participant's ability to follow the protocol or achieve study objectives; * Psychological or sociological conditions, addictive disorders, or family problems that would preclude adherence with study drug or compliance with the protocol * Women who report pregnancy, are breast feeding, or have a positive pregnancy test; * Use of CoQ10 supplement use within 30 days of initiating study drug; * Use of over-the-counter nutritional vitamin greater than 5x RDA; * Fish allergy (due to fish-based softgel shell); * Currently taking FDA cardioprotective drugs, such as Zinecard (dexrazoxane); * History of chronic hepatitis B, hepatitis C, and HIV infection; * Problems swallowing oral medications due to prolonged emesis, mucositis, esophageal dysfunction, etc.; and, * Currently taking any form of antioxidant supplements while on study. * Use of warfarin. * Kosher (due to fish-based softgel shell) * Dietary restriction of tilapia (due to tilapia fish-based softgel shell) * Titanium Dioxide allergy (due to the opaque coloring used in the softgel).
