Further study details as provided by Bayer:

Primary Outcome Measures:
  • To determine the major hematologic response rate (i.e. complete and partial hematologic responses) associated with BAY 43-9006 in patients with chronic phase CML resistant to Gleevec. [ Time Frame: Every 3 months ]

Secondary Outcome Measures:
  • To determine the cytogenetic response rate associated with BAY 43-9006. [ Time Frame: Every 3 months ]
  • To evaluate the duration of hematologic response to BAY 43-9006. [ Time Frame: Throughout study until end of response ]
  • To evaluate the duration of cytogenetic response to BAY 43-9006. [ Time Frame: Throughout study until end of response ]
  • To assess time to progression. [ Time Frame: Until event occurs ]
  • To assess overall survival.. [ Time Frame: During Follow up ]
  • To evaluate the molecular response and to perform the pharmacodynamic assessment by analysis the following biomarkers: phospho-Erk, Crkl, phospho-S6 [ Time Frame: At 2 months and at last visit ]
  • To assess the safety of BAY 43-9006 in patients with chronic phase CML resistant to Gleevec. [ Time Frame: Ongoing ]

Enrollment: 10
Study Start Date: January 2004
Study Completion Date: February 2005
Primary Completion Date: February 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1 Drug: Nexavar (Sorafenib, BAY43-9006)
Patients will receive Bay 43-9006 400 mg po twice daily in a continuous, uninterrupted schedule. Treatment will continue until there is objective evidence of disease progression, or until evidence of toxicities that are unacceptable and thought to be related to study drug, which requires discontinuation of drug, or due to withdrawn patient consent.
