Brief Summary:

In order for a tumour to grow and spread to other parts of the body, it needs to have a blood supply. Certain proteins in the body, called cytokines or growth factors, have been shown to cause the growth of new blood vessels that supply tumours and therefore help the tumour to grow and spread. Motesanib (AMG 706) prevents these proteins from working, and may help to prevent the growth of tumours.

In the first part of this study, we will look at the way your body absorbs this drug into your blood, how your body changes and breaks down the drug, and then how the drug leaves your body in your urine and faeces.

In order to provide potential treatment benefit for the subjects who participated in the first part of the study, the second part of the study will allow subjects to continue on motesanib (AMG 706) treatment. The estimated length of this part of the study is unknown, and dependent on how subjects respond to motesanib (AMG 706).

Condition or disease Intervention/treatment Phase
Advanced Solid Tumors Drug: AMG 706 Phase 1

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 4 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: An Open-label, Single Dose Study of the Mass Balance and Metabolic Disposition of Orally Administered [14C]-Labelled AMG 706 (Motesanib) Followed by Extended Treatment With Motesanib in Patients With Advanced Solid Tumors
Study Start Date : May 2009
Actual Primary Completion Date : November 2010
Actual Study Completion Date : December 2010

Arm Intervention/treatment
Experimental: A Drug: AMG 706
Single oral dose of 125 mg AMG 706 (motesanib) containing 100 μCi of [14C]-AMG 706 followed by option to continue onto a treatment extension phase for potential treatment benefit. Subjects will be administered motesanib 125 mg (5 x 25 mg tablets) on a daily basis until subjects experience a dose-limiting toxicity (DLT), an unacceptable AE, disease progression, or voluntary withdrawal.

Primary Outcome Measures :
  1. Profile and identification of metabolites of [14C]-AMG 706 in plasma, urine, and faeces
  2. Pharmacokinetics of total radioactivity in plasma and whole blood
  3. The mass balance of [14C]-AMG 706 (as the percentage of the dose administered) in urine and faeces

Secondary Outcome Measures :
  1. • Measure the area under the plasma concentration curve versus time of AMG 706, as well as determine half-life and time of maximum concentration of AMG 706.
  2. The subject incidences of serious adverse events, adverse events, and clinically significant changes in vital signs and clinical laboratory tests

  • Systemic chemotherapy within 28 days of Day 1
  • Radiotherapy within 28 days of Day 1 or within 14 days of Day 1 for peripheral lesions
  • Experimental or approved antibody therapy within 6 weeks before Day 1
  • Concurrent or prior (within 4 weeks prior to Day 1 of 5 half-lives of the medication which ever is longer) treatment with potent CYP3A inducers, including but not limited to : phenytoin, carbamazepine, rifampicin, phenobarbital and St John's Wort
  • Concurrent or prior (within 2 weeks prior to Day 1 or 5 half-lives of the medication which ever is longer) treatment with potent CYP3A inhibitors, including but not limited to: ketoconazole, itraconazole, fluconazole, clarithromycin, erythromycin, cyclosporine, tacrolimus, nefazodone and/or HIV protease inhibitors
