Paclitaxel, Carboplatin, and Bevacizumab With or Without Cixutumumab in Treating Patients With Stage IV or Recurrent Non-small Cell Lung Cancer

PRIMARY OBJECTIVES:

I. To evaluate the progression-free survival with the combination of carboplatin, paclitaxel,
and bevacizumab, and +/- IMC-A12 (cixutumumab) in patients with advanced, non-squamous,
non-small cell lung cancer.

SECONDARY OBJECTIVES:

I. To evaluate overall survival and response rate of the above combination in patients with
non-squamous, advanced non-small cell lung cancer.

II. To evaluate the toxicities of the above combination in patients with non-squamous
advanced non-small cell lung cancer.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A (CPB): Patients receive carboplatin intravenously (IV) over 30 minutes, paclitaxel IV
over 3 hours, and bevacizumab IV over 30-90 minutes on day 1.

ARM B (CPB+cixutumumab): Patients receive carboplatin, paclitaxel, and bevacizumab as in Arm
A. Patients also receive cixutumumab (IMC-A12) IV over 1 hour on days 1, 8, and 15.

In both arms, treatment repeats every 21 days for 6 courses in the absence of disease
progression or unacceptable toxicity. Treatment with bevacizumab and cixutumumab may continue
in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and
then every 6 months for 3 years.

Inclusion Criteria:

- Histologically or cytologically confirmed with non-squamous, non-small cell lung
cancer (NSCLC)

- Advanced NSCLC defined as either recurrent disease after prior radiation or surgery or
stage IV (M1a or M1b) based on the TNM staging system (American Joint Committee on
Cancer [AJCC] 2009)

- Measurable disease as defined by the revised Response Evaluation Criteria in Solid
Tumors (RECIST version 1.1). All sites of disease (of target and non-target disease
sites) must be obtained within 4 weeks prior to randomization

- A head computed tomography (CT) or magnetic resonance imaging (MRI) required within 4
weeks prior to randomization

- Prior radiation therapy (RT) is allowed if it has been completed 3 weeks prior to
randomization and patient has recovered from any adverse events related to RT

- Brain metastases are allowed, provided they have been treated with surgery and/or
radiotherapy, the patient is neurologically stable, and repeat brain imaging shows no
progression in the brain; at least 6 weeks should have elapsed from the time of
craniotomy and at least 4 weeks from radiotherapy

- Eastern Cooperative Oncology Group (ECOG) performance status 0-1

- Fasting blood glucose within normal range (fasting < 120 mg/dL or below ULN)

- Alkaline phosphatase (ALP) ≤ 3 x ULN

- Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3 x ULN

- Urine dipstick must be ≤ 0-1+ within 2 weeks (14 days) of randomization; if urine
dipstick result is > 1+, a calculation of urine protein creatinine (UPC) ratio is
required; patients must have a UPC ratio < 1.0 to participate in the study

- Neuropathy, if present at baseline, must be ≤ Common Terminology Criteria for Adverse
Events (CTCAE) grade 1

- Patients with a history of hypertension must be well-controlled (≤ 150/90) on a stable
regimen of anti-hypertensive therapy

- Women of childbearing potential and sexually active males should use an accepted and
effective method of contraception while on treatment and for 3 months thereafter

Exclusion Criteria:

- Prior chemotherapy or biologic/molecular targeted therapy for advanced NSCLC. Prior
chemotherapy and/or biological/molecular targeted therapy as part of initial
potentially curative therapy (one regimen of induction and/or adjuvant and/or
concurrent chemoradiotherapy) was allowed provided it had been completed 1 year or
more prior to randomization

- Prior treatment with IMC-A12 or another insulin-like growth factor 1 receptor (IGF-1R)
inhibitor

- Patients on therapeutic anticoagulation; patient's international normalized ratio
(INR) must be ≤ 1.5 or partial thromboplastin time (PTT) ≤ upper limits of normal
within 2 weeks prior to randomization to be eligible; prophylactic anticoagulation of
venous access devices is allowed provided the above criteria have been met

- Prior allergic reaction to compounds of chemical or biologic composition similar to
those of IMC-A12

- Hypersensitivity to any component of bevacizumab

- Poorly controlled diabetes mellitus

- History of other invasive malignancies unless there is no active disease and all
treatment has been completed ≥ 3 years prior to randomization; patients with history
of in-situ malignancies and curatively resected nonmelanomatous skin cancer are
eligible

- History of thrombotic or hemorrhagic disorders

- History of bleeding diathesis or coagulopathy

- ≥ grade 2 bleeding or any bleeding requiring intervention within 4 weeks prior to
randomization

- New York Heart Association (NYHA) > class II congestive heart failure or severe
heart failure

- Unstable or symptomatic angina pectoris

- History of stroke

- Significant vascular disease

- Symptomatic peripheral vascular disease

- Ongoing, serious cardiac arrhythmia requiring medication at time of randomization

- Ongoing, active infection or ongoing fever at the time of randomization or any
co-existing medical condition, psychiatric illness or limitations that would interfere
with compliance of study requirements
