Brief Summary:

The purpose of this study is to determine whether or not XL184 demonstrates anti-tumor activity in selected tumor types under a randomized discontinuation trial (RDT) design. Subjects who have responded to study drug after 12 weeks of open-label XL184 administration will continue to take XL184. Subjects who are clearly progressing will discontinue study treatment and subjects who demonstrate stable disease will be randomized to either XL184 or placebo. For individual patients, once disease progression is observed, the blind will be broken and subjects who were randomized to placebo will be offered the option to receive open-label XL184. Subjects who progressed while taking XL184 will discontinue study treatment.

Emerging data may support enrollment in an open-label, non-randomized expansion cohort (NRE). There will be NRE cohorts for prostate and ovarian cancers.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Arm 1
RDT Open-Label
 Drug: XL184
All subjects receive 100 mg XL184 (supplied at 19.7-, 50-, and 60-mg strength capsules) daily for 12 weeks. Subjects with a partial or complete response will continue daily XL184 administration until disease progression. Subjects with stable disease will be randomized to Arm 2 or 3.
Experimental: Arm 2
RDT Randomized Blinded-XL184
 Drug: XL184
After 12 weeks of open-label daily XL184, subjects with stable disease randomized to Arm 2 will continue to receive XL184 (blinded) administered daily until disease progression.
Placebo Comparator: Arm 3
RDT Randomized Blinded
 Drug: Placebo
After 12 weeks of open-label daily XL184, subjects with stable disease randomized to Arm 3 will receive capsules of placebo that are size- and color-matched to XL184 administered daily until disease progression. Subjects will be unblinded at disease progression and, if found to be receiving placebo, given the option to receive XL184.
Experimental: Non-Randomized Expansion (NRE) Cohorts
Drug: XL184
 Drug: XL184
All subjects receive open-label, 100 mg XL184 (supplied at 19.7-, 50-, and 60 mg strength capsules) daily until disease progression.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. To evaluate the efficacy of XL184 in subjects with advanced solid tumors [ Time Frame: Assessed approximately every 6 weeks using MRI, CT, and/or bone scans ]

Secondary Outcome Measures :
  1. Safety and tolerability of XL184 in subjects with advanced solid tumors [ Time Frame: Assessed approximately every 3 weeks, during study visits ]
  2. To correlate the pathway dysfunction of disease-related genes or proteins such as MET and downstream signaling molecules with clinical outcome [ Time Frame: Assessed approximately every 6 weeks through blood samples and tumor biopsies ]
  3. To further characterize the pharmacokinetic (PK) and pharmacodynamic parameters of XL184 [ Time Frame: Assessed approximately every 6 weeks through blood samples ]

  • The subject has documented progressive disease at screening
  • Subjects having any tumor type of other than CRPC must have at least one lesion that is not within a previously irradiated field and is measurable on CT or MRI scan
  • The subject has recovered to baseline or CTCAE ≤ Grade 1 from toxicities related to prior treatment (some exceptions apply)
  • The subject is ≥ 18 years old on the day of consent
  • Tissue samples from archival or fresh tissue, or a tissue block of the subject's tumor
  • The subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • The subject has adequate organ function
  • The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document
