Erlotinib Pharmacokinetics During Doxycycline Treatment for Erlotinib-induced Rash
February 24, 2015 updated by: Northwestern University
Evaluation of Erlotinib Pharmacokinetics During Doxycycline Treatment for Erlotinib-induced Rash
A side effect occurring in a majority of patients taking erlotinib (Tarceva®) consists of a skin rash.
Sometimes, symptoms associated with the rash necessitate erlotinib dose reduction or discontinuation.
Some physicians have successfully treated the erlotinib-induced rash with doxycycline.
At the same time, it has been observed that in patients who develop the erlotinib rash, the cancers respond better to erlotinib treatment.
This research study is designed to determine how well doxycycline treats the erlotinib rash and whether doxycycline affects the blood levels of erlotinib.

- Patients must have signed informed consent prior to registration on study.
- Currently receiving erlotinib therapy at 150 mg per day for locally advanced or metastatic NSCLC.
- Patients - both males and females - with reproductive potential (ie, menopausal for less than 1 year and not surgically sterilized) must utilize barrier methods in combination with spermicidal agents for contraception when engaging in sexual intercourse. Women of childbearing potential must provide a negative pregnancy test (serum or urine) within 14 days prior to registration.

- Photosensitivity or lupus erythematosus.
- Active gastroesophageal reflux disease.
- Women who have a positive pregnancy test or are lactating by history.
- ECOG performance status ≤3.
- Self report of current smoking or history of smoking within 60 days of screening, or positive urine cotinine test.
Current use of agents that are known to be strong inducers or inhibitors of CYTP3A4:
- inhibitors: atazanavir, clarithromycin, indinavir, itraconazole, ketoconazole, nefazodone, nelfi navir, ritonavir, saquinavir, telithromycin, troleandomycin (TAO), voriconazole, grapefruit or grapefruit juice
- inducers: rifampicin, rifabutin, rifapentine, phenytoin, carbamazepine, phenobarbital, and St. John's Wort
Impaired hepatic function (≤ 30 days before randomization):
