Amgen discontinued the development of AMG706 because 20050201 did not meet its primary objective.

To determine if treatment with AMG 706 (motesanib diphosphate) in combination with paclitaxel and carboplatin improves overall survival compared to treatment with placebo in combination with paclitaxel and carboplatin in subjects with advanced non-squamous NSCLC and in subjects with adenocarcinoma histology (adenocarcinoma subpopulation).

• Platelet count > = 100 x 109/L and < = 850 x 109/L
• Hemoglobin > =9 g/dL
• Renal function, as follows:
• Creatinine clearance > 40 mL/min (calculated by Cockcroft Gault formula)
• Urinary protein quantitative value of < = 30 mg in urinalysis or < = 1+ on dipstick unless quantitative protein is < 500 mg in a 24 hour urine sample
• Hepatic function, as follows:
• Aspartate aminotransferase (AST) < =2.5 x upper limit of normal (ULN) OR AST < 5 x ULN if liver metastases are present

Exclusion Criteria:

• Subjects with adenosquamous histology or an unclear histology subtype (eg, not otherwise specified) containing greater than 10% squamous cells

Subjects with a history of brain metastases are eligible if definitive therapy has been administered (surgery and/or radiation therapy), there is no planned treatment for brain metastases, and the subject is clinically stable and is off corticosteroids for at least 2 weeks prior to randomization.
• Prior chemotherapy as follows: Any prior chemotherapy for advanced non squamous NSCLC
• Any prior adjuvant chemotherapy for non squamous NSCLC within 52 weeks prior to randomization. Adjuvant chemotherapy completed > 52 weeks prior to randomization is permitted. Any prior chemoradiation for locally advanced stage III disease.
• Prior (within 30 days of randomization) yellow fever vaccination.
• Central (chest) radiation therapy within 28 days prior to randomization, radiation therapy within 14 days prior to randomization for peripheral lesions.
• History of pulmonary hemorrhage or gross hemoptysis (approximately 3 mL of bright red blood or more) within 6 months prior to randomization.
• Prior targeted therapies, including but not limited to:
• AMG 706, inhibitors of VEGF (eg, SU5416, SU6668, ZD6474, SU11248, PTK787, AZD2171, AEE 788, sorafenib, bevacizumab), or EGFr (eg, panitumumab, cetuximab, gefitinib, erlotinib).
• Known history of allergy or hypersensitivity reaction to paclitaxel or carboplatin.
• Any anticoagulation therapy within 7 days prior to randomization. The use of low-dose warfarin [ < = 2 mg daily] or low molecular weight heparin or heparin flushes for prophylaxis against central venous catheter thrombosis is allowed.
• History of arterial or venous thrombosis within 12 months prior to randomization.
• History of bleeding diathesis or bleeding within 14 days prior to randomization.
• Peripheral neuropathy > grade 1 per Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0.
• Clinically significant cardiac disease within 12 months of randomization, including myocardial infarction, unstable angina, grade 2 or greater peripheral vascular disease, cerebrovascular accident, transient ischemic attack, percutaneous transluminal coronary angioplasty/stent, congestive heart failure, or ongoing arrhythmias requiring medication.
• History of other primary cancer unless: Curatively resected non melanomatous skin cancer. Curatively treated cervical carcinoma in situ. Other primary solid tumor curatively treated with no known active disease present and no curative treatment administered for the last 3 years
• Any kind of disorder that compromises the ability of the subject to comply with the study procedures.
• Open wound, ulcer or fracture.
• Uncontrolled hypertension as defined by resting blood pressure > 150/90 mm Hg. Antihypertensive medications are allowed if the subject is stable on their current dose at the time of randomization.
• Surgery:
• Major surgical procedures within 28 days prior to randomization
• Minor surgical procedures within 14 days prior to randomization
• Failure to recover from prior surgery
• Placement of a central venous access device (including ports and tunneled or non-tunneled catheters) within 7 days prior to randomization
• Planned elective surgery while on study treatment
• Core needle biopsy within 7 days prior to randomization
• Not recovered from all previous therapies (ie, radiation, surgery and medications). Adverse events related to previous therapies must be CTCAE grade < = 1 at screening or returned to the subject's baseline prior to their most recent previous therapy.
• Participation in therapeutic clinical trials or currently receiving other investigational treatment(s) within 30 days prior to randomization.
• Pregnant (eg, positive HCG test-serum or urine) or breast feeding woman.
• 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.
• Known to be human immunodeficiency virus (HIV), hepatitis B surface antigen or hepatitis C positive.
• Known chronic hepatitis.
• Active infection requiring systemic treatment or any uncontrolled infection < = 14 days prior to randomization.
