Test Uniformity of Transdermal Drug Delivery to Breast Using Diclofenac Epolamine
This trial is active, not recruiting.
|Treatment||diclofenac epolamine patch|
|Start date||June 2011|
|End date||July 2017|
|Trial size||25 participants|
|Trial identifier||NCT01380353, NU 10B05, STU00042939|
The purpose of this study is to look for ways to improve breast cancer treatment by giving breast cancer drugs through the skin of the breast.
The drug used in this study is a diclofenac epolamine patch and is a nonsteroid anti-inflammatory pain reliever. The drug amount that gathers in the breast, after application of a patch to the skin of the breast, will be measured and compared to the amount that is found in the breast when the patch is applied to the skin of the belly.
|Endpoint classification||safety/efficacy study|
|Intervention model||parallel assignment|
Compare concentrations of diclofenac epolamine patch when applied to breast vs. abdomen
time frame: after 3 days of treatment prior to surgery
Determine how the concentrations of the study patch is distributed in the breast.
time frame: after three days of treatment prior to surgery

- Ability to understand and the willingness to sign a written informed consent.
- Participants must have normal organ and marrow function
- Prior history of ipsilateral breast radiotherapy.
- Pregnant women and those who will be actively breast-feeding in the preoperative period will be excluded.

|Official title||Pilot Study to Test Uniformity of Transdermal Drug Delivery to the Breast Using Diclofenac Epolamine as a Model|
|Principal investigator||Seema Khan, MD|
|Description||This is a randomized study where participants in group 1 will apply the diclofenac epolamine patch to the breast and participants in group 2 will apply the same drug to her abdomen. Participants are instructed to apply a new patch every 12 hours for 3 days. Total participation in this study will be for three days, ending on the day of surgery. On the day of surgery, participants will have blood drawn to measure the level of diclofenac epolamine in the body, and the final patch will be removed.|
