|Brief Title ICMJE||Chemical and Genetic Effects of the Experimental Anti-Cancer Drugs in Cheek Cells in Cancer Patients|
|Official Title ICMJE||Molecular, Genetic, and Biochemical Effects Of Novel Therapies In Buccal Mucosal Cells|
This study will examine the effects of certain investigational anti-cancer drugs on the genetic and protein makeup of cells. The findings will be entered into a database that may be used to: 1) determine the optimal dose of drug that will provide the most benefit with the least harmful side effects; and 2) predict which patients will have a greater chance of developing side effects or a greater chance of benefiting from the drug.
Patients 18 years of age and older who are receiving the anti-cancer drugs flavopiridol or perifosine in an NIH clinical trial may be eligible for this study.
Participants will undergo the following procedures both before starting treatment and during the first treatment cycle to look for genetic or chemical changes produced in response to the study drug:
|Detailed Description||A significant problem in drug development of novel small molecules is the lack of available tissues (surrogate tissues) that allow for the assessment of the molecular and biochemical effects of (targeted-therapies) drug action. The information obtained from surrogate tissues might help us validate previous preclinical studies with those agents and also dose them in a more rational way. Oral keratinocytes, which are accessible by non-invasive means, might be useful to assess drug action. The proposed study seeks to investigate the genetic, molecular, and biochemical effects of novel agents in oral buccal mucosal cells. Patients already enrolled in Phase I and II clinical trials for neoplastic diseases at the Clinical Center will undergo oral cytobrushing before and during therapy to determine the molecular and biochemical effects of novel agents in the oral mucosa cells. Similar studies will be performed in peripheral blood mononuclear cells. In order to validate to compare and compare the oral cytobrush methodology, some of these subjects will undergo oral punch biopsy studies. Some of these subjects will also undergo tumor biopsy, if accessible or available.|
