Primary Outcome Measures:
  • Phase I: Determine recommended dose for phase II studies of CP-4055 when given five consecutive days twice in a 4 week schedule, D1-5 and D8(+2)-12(+2) q4w [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]
  • Phase II: Determine the antitumour activity of CP-4055 [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determine pharmacokinetic (PK) parameters [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]
  • Explore the time to progression (TTP) [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]
  • Investigate the duration of tumour response [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]
  • Determine the nature and degree of toxicity of CP-4055 in this patient population [ Time Frame: August 2009/June 2010 ] [ Designated as safety issue: No ]

Enrollment: 28
Study Start Date: April 2008
Study Completion Date: April 2010
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Open label CP-4055
Phase I: Dose escalation Phase II: Fixed dose
Drug: CP-4055
D1-5 and D8(+2)-12(+2) q4w
Drug: CP-4055
IV administration day 1-5 and day 8-12 in a 4 week schedule

Detailed Description:

Phase I

  • Three eligible patients will be enrolled at each dose level (DL), according to standard dose escalation decision rules
  • Patients will receive CP-4055 at increasing DLs until the maximum tolerated dose and the recommended dose (RD) have been established

Phase II

  • Step 1 (The patient inclusion may stop after this step):

    • Patients will be enrolled at the RD until there are maximum 16 evaluable patients at this DL
  • Step 2:

    • Depending on the response rate at step 1, up to 26 patients will be included and treated at step 2

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female

  • Pregnancy or breastfeeding
  • Known positive status for HIV and/or hepatitis B or C
