A Drug-Drug Interaction Study of the Effects of XL184 on Rosiglitazone in Subjects With Solid Tumors

2014-07-23 21:09:35 | BioPortfolio


The primary objective of this clinical study is to determine whether the inhibition of cytochrome P450 (CYP) isozyme CYP2C8 by XL184 observed in in vitro preclinical studies translates into the potential for clinically significant drug-drug interactions in humans. The study will measure the effect of once daily dosing of XL184 on the pharmacokinetics (PK) of rosiglitazone. The PK of XL184 when combined with rosiglitazone will be evaluated as well.

A specific objective of this study is to determine whether the interaction between XL184 and a drug such as rosiglitazone is sufficiently large enough to necessitate a dosage adjustment when used in combination with XL184, or whether the interaction would require additional therapeutic monitoring.

Rosiglitazone, commonly known as Avandia, is a prescription medicine approved by the FDA used to treat adults with Type 2 (adult-onset or non-insulin dependent) diabetes mellitus (high blood sugar). In this study, subjects will only take 2 doses of rosiglitazone. There is no intention of therapy as a result of taking rosiglitazone in this study.

Medical and Biotech [MESH] Definitions

A thyroid neoplasm of mixed papillary and follicular arrangement. Its biological behavior and prognosis is the same as that of a papillary adenocarcinoma of the thyroid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1271)

An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.

Tumors or cancer of the THYROID GLAND.

A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.

An adenocarcinoma containing finger-like processes of vascular connective tissue covered by neoplastic epithelium, projecting into cysts or the cavity of glands or follicles. It occurs most frequently in the ovary and thyroid gland. (Stedman, 25th ed)
