Single Dose Study of [14C]-Labelled AMG 706 in Patients With Advanced Solid Tumors

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

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).

• Subjects with head and neck cancer
• Subjects with ovarian cancer
• Subjects with large central (located adjacent to or within the hilum or mediastinum) tumor lesions ≥ 3 cm, regardless of histology
• Uncontrolled hypertension: average systolic blood pressure > 150 mm Hg or average diastolic blood pressure > 90 mm Hg (average blood pressure of the three separate blood pressure values measured within 10 minutes during screening)
• 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
• Concurrent or prior (within 2 weeks prior to Day 1) consumption of grapefruit (i.e. whole fruit or fruit juice)
• Subjects who as a result of gastrointestinal surgeries (including cholecystectomy) or a medical condition (e.g. constipation, cholecystitis / cholelithiasis) that will significantly alter the absorption, metabolism or excretion of motesanib.
• Subjects with irregular bowel habits (more than 3/day or less than 1 every 2 days).
• Subjects who will not refrain from taking herbal/ complementary therapies (which have the potential to alter the absorption, metabolism, or excretion of the [14C]-AMG 706) for 7 days before first dosing, and for the duration of the ADME part of the study.
• Concurrent immune modulators such as cyclosporine and tacrolimus
• Any anti-coagulation therapy within 7 days prior to Day 1

• Major surgery (that which requires general anesthesia) within 28 days or minor surgery within 14 days of Day 1
• Any kind of disorder that compromises the ability of the subject to give written informed consent and/or comply with the study procedures
• History of any medical or psychiatric condition or laboratory abnormality that in the opinion of the investigator may increase the risks associated with study participation or investigational product administration or may interfere with the interpretation of the study results
• Known positive test for human immunodeficiency virus infection, hepatitis C virus, chronic active hepatitis B infection or any co-morbid disease that would increase risk of toxicity
• Any subject not consenting to use adequate contraceptive precautions (eg, hormonal, barrier or abstinence) during the course of the study and for 6 months after the last treatment

Arms and Interventions

Participant Group / 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.
