The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
The purpose of this study is to: a) Determine how the body takes up the test drug and distributes it into various body organs and tissues, how it processes the drug and how it ultimately removes it; and b) Examine how well the test drug works against cancer, and whether it is safe and tolerable to take

Condition Intervention Phase
Neoplasms Drug: Sagopilone (BAY 86-5302, ZK 219477) Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)

Official Title: Investigation of Mass Balance and Major Metabolites After Administration of 28 mg Radiolabeled ZK 219477 in Patients With Solid Tumor in an Open-label, Non Randomized Design

Further study details as provided by Bayer:

Primary Outcome Measures:
  • Blood, urine and fecal samples will be collected over a period of 336 hours (14 days) to measure 14C, ZK 219477 and its major metabolites following the intravenous administration of 14C-ZK 219477. [ Time Frame: 14 days ]
  • Cmax [ Time Frame: 14 days ]
    Maximum plasma concentration for [14C]-ZK 219477, ZK 219477

  • tmax [ Time Frame: 14 days ]
    Time to Cmax for [14C]-ZK 219477, ZK 219477

  • AUC [ Time Frame: 14 days ]
    Area under the concentration time curve for [14C]-ZK 219477, ZK 219477

  • AUC(0-tlast) [ Time Frame: 14 days ]
    AUC from administration until the last time point with measurable concentration for [14C]-ZK 219477, ZK 219477

  • AUC(0-24) [ Time Frame: 14 days ]
    AUC from time zero to 24 hours for [14C]-ZK 219477, ZK 219477

  • MRT [ Time Frame: 14 days ]
    Mean residence time for [14C]-ZK 219477, ZK 219477

  • t1/2 [ Time Frame: 14 days ]
    Terminal half-life for [14C]-ZK 219477, ZK 219477

  • λz [ Time Frame: 14 days ]
    Apparent terminal rate constant for [14C]-ZK 219477, ZK 219477

  • CL [ Time Frame: 14 days ]
    Total clearance for ZK 219477

  • Vss [ Time Frame: 14 days ]
    Apparent volume of distribution at steady state for ZK 219477

  • Vz [ Time Frame: 14 days ]
    Apparent volume of distribution during terminal phase for ZK 219477

Secondary Outcome Measures:
  • Number of participants with adverse events [ Time Frame: Approximately 12 weeks to 30 weeks ]
  • Overall response [ Time Frame: Approximately 10 to 32 weeks ]
    Determination of complete response (CR), partial response (PR), unknown, stable disease, progressive disease (PD) by the modified Response Evaluation Criteria in Solid Tumors

  • Best overall response [ Time Frame: Approximately 10 to 32 weeks ]
    Overall response as obtained at all time points available for an individual subject combined to the 'best overall response'

  • Responders [ Time Frame: Approximately 10 to 32 weeks ]
    'Response' was considered to be established if 'Best overall response' of PR or CR was confirmed at any time after the start of study treatment. If response was established, a subject was referred to as a 'responder'

Enrollment: 7
Study Start Date: January 2007
Study Completion Date: November 2007
Primary Completion Date: November 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Sagopilone
Subjects received 28 mg ZK 219477, containing 14 kBq/7.8 µg [14C]-ZK 219477 in the first infusion (Treatment course 1) followed by subsequent infusions (Treatment courses 2 to n [till disease progression]) of 16 mg/m2 ZK 219477 without radioactive label. Interval between the treatments was at least 21 days.
Drug: Sagopilone (BAY 86-5302, ZK 219477)
First infusion only: 28 mg, containing 14 kBq/7.8 mcg [14C]-ZK 219477. Subsequent infusions: 16 mg/m2 ZK 219477 without radioactive label. IV infusion was given over a period of 30 min.
