Study of CoQ10 During One Cycle of Doxorubicin Treatment for Breast Cancer

2014-08-27 03:19:23 | BioPortfolio


This research study hopes to examine the effects of Coenzyme Q10 on doxorubicin (Adriamycin) metabolism during breast cancer treatment. 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 in a maximum of 18 patients. Safety will be assessed by measuring 1) intra-patient differences in doxorubicin and its active metabolites, with and without CoQ10, and 2) adverse events. We hypothesize 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.

Medical and Biotech [MESH] Definitions

S-Acyl coenzyme A. Fatty acid coenzyme A derivatives that are involved in the biosynthesis and oxidation of fatty acids as well as in ceramide formation.

A coenzyme A derivative which plays a key role in the fatty acid synthesis in the cytoplasmic and microsomal systems.

A ferredoxin-containing enzyme that catalyzes the COENZYME A-dependent oxidative decarboxylation of PYRUVATE to acetyl-COENZYME A and CARBON DIOXIDE.

Natural compounds containing alternating carbonyl and methylene groups (beta-polyketones), bioenergenetically derived from repeated condensation of acetyl coenzyme A via malonyl coenzyme A, in a process similar to fatty acid synthesis.

Enzymes which transfer coenzyme A moieties from acyl- or acetyl-CoA to various carboxylic acceptors forming a thiol ester. Enzymes in this group are instrumental in ketone body metabolism and utilization of acetoacetate in mitochondria. EC 2.8.3.
