Study of XL184 (Cabozantinib) in Adults With Advanced Malignancies

This study has been completed.
Information provided by (Responsible Party):
Exelixis Identifier:
First received: September 20, 2005
Last updated: February 26, 2013
Last verified: February 2013
The purpose of this study is to determine the best and safest dose of XL184 administered orally. XL184 is a new chemical entity that inhibits VEGFR2, MET and RET, kinases implicated in tumor formation, growth and migration. To determine the highest safe dose, subjects will receive different amounts of the drug. The first group of subjects will receive the lowest dose of XL184. As long as no medically unacceptable side effects are noted, the dose will be increased for the next group. When the maximum tolerated dose (MTD) is reached, at least 20 subjects with Medullary Thyroid Cancer (MTC) will be enrolled to evaluate the effect of XL184 in this population.

Further study details as provided by Exelixis:

Primary Outcome Measures:
  • Safety, tolerability, maximum tolerated dose (MTD), and dose-limiting toxicity of oral administration of XL184 [ Time Frame: Assessed during periodic visits ]
  • Evaluate plasma pharmacokinetics and estimate renal elimination of oral administration of XL184 [ Time Frame: Assessed during periodic visits ]

Secondary Outcome Measures:
  • Long-term safety/tolerability of XL184 after oral administration for up to 1 year [ Time Frame: Assessed during periodic visits ]
  • Evaluate preliminary tumor response after repeated XL184 administration [ Time Frame: Assessed during periodic visits ]
  • In MTD expanded cohort: Progression-free survival and duration of response in subjects with advanced or recurrent medullary thyroid cancer [ Time Frame: Assessed during periodic visits ]
