Phase 2 Study of Maintenance OSI-906 Plus Erlotinib (Tarceva®), or Placebo Plus Erlotinib in Patients With Nonprogression Following 4 Cycles of Platinum-based Chemotherapy

Adult patients with advanced Non-small Cell Lung Cancer (NSCLC) and nonprogression after
platinum-based chemotherapy will be randomized 1:1 to receive either OSI-906 plus erlotinib
or placebo plus erlotinib.

Inclusion Criteria:

- Histologically confirmed locally advanced or metastatic stage IIIB or IV NSCLC

- Have experienced Complete Response (CR), Partial Response (PR) or Stable Disease (SD)
following completion of 4 cycles of first-line platinum-based chemotherapy and are not
progressing at time of entry into study (prior completed first-line combination
bevacizumab therapy is permitted; however, current use of maintenance bevacizumab is
not permitted. A maximum interval of 28 days between the last day of the treatment
cycle and randomization

- Patient has recovered from prior chemotherapy-related toxicity to ≤ grade 2

- EGFR mutation status must be confirmed for participation in the study. EGFR analysis
can be performed either by central or local laboratory. If analysis is done locally,
verifiable documentation confirming the EGFR mutation status must be submitted for
review and approval by APGD prior to randomization. If no local result is available,
formalin-fixed, paraffin-embedded archival tissue representative of the tumor or in
the absence of archival tissue, a fresh tumor tissue sample of sufficient size to
perform EGFR mutation analysis must be submitted centrally. Results of the central
analysis must be available prior to randomization. Additionally, subjects should
provide tissue blocks centrally for biomarker analysis whenever possible. Ideal tissue
requirement: block with ≥5 mm2 tumor area sufficient to provide four 4-micron, and
five 10-micron sections)

- Measurable disease (for those patients with PR or SD after first-line platinum-based
chemotherapy) according to Response Evaluation Criteria in Solid Tumors (RECIST)
(version 1.1)

- Eastern Cooperative Oncology Group (ECOG) Performance Status(PS) 0 - 1

- Previous adjuvant or neo-adjuvant treatment is permitted

- Must be able to take oral medication

- Fasting glucose ≤ 150 mg/dL (8.3 mmol/L). Concurrent use of non-insulinotropic
antihyperglycemic therapy is permitted if the dose has been stable for ≥ 4 weeks at
the time of randomization

- Adequate hematopoietic, hepatic, and renal function defined as follows:

- Neutrophil count ≥ 1.5 x 109/L

- Platelet count ≥ 100 x 109/L

- Bilirubin ≤ 1.5 x Upper Limit of Normal (ULN)

- AST and ALT ≤ 2.5 x ULN, or ≤ 5 x ULN if patient has documented liver metastases

- Serum creatinine ≤ 1.5 x ULN

- Potassium, magnesium and calcium within normal limits (supplementation and retesting
is permitted)

Female patient must be either:

- Of non child bearing potential:

- post-menopausal (defined as at least 1 year without any menses) prior to

Screening, or

- documented surgically sterile or status post hysterectomy (at least 1 month prior to
Screening)

- Or, if of childbearing potential:

- must have a negative urine pregnancy test at Screening, and

- must use two forms of birth control (one of which must be a barrier method) starting
at Screening and throughout the study period and for 30 days after final study drug
administration

- Female patient must not be breastfeeding at Screening or during the study period
and for 30 days after final study drug administration

- Female patient must not donate ova starting at Screening and throughout the study
period and for 30 days after final study drug administration

- Male patient and their female spouse/partners who are of childbearing potential
must be using highly effective contraception consisting of two forms of birth
control (one of which must be a barrier method) starting at Screening and
continue throughout the study period and for 30 days after final study drug
administration

- Male patient must not donate sperm starting at Screening and throughout the study
period and for at least 30 days after final study drug administration

- Prior radiation therapy is permitted provided patients have recovered from acute
toxic effects of radiotherapy prior to randomization. A minimum of 28 days must
have elapsed between the end of radiotherapy and randomization

- Prior surgery is permitted provided that the surgery was performed 21 days prior
to randomization and adequate wound healing has occurred prior to randomization

- Patients must provide written (signed) informed consent to participate in the
study and for use of tumor tissues

Exclusion Criteria:

- Prior exposure to agents directed at the Human Epidermal Receptor (HER) axis (eg,
erlotinib, gefitinib, cetuximab, and trastuzumab)

- Malignancies other than NSCLC within past 3 years (exceptions if curatively treated:
basal or squamous cell carcinoma of skin; locally advanced prostate cancer; ductal
carcinoma in situ of breast; in situ cervical carcinoma; and superficial bladder
cancer)

- Type 1 diabetes mellitus or Type 2 diabetes mellitus currently requiring
insulinotropic or insulin therapy

- Prior insulin-like growth factor receptor (IGF-1R)

- Prior investigational agent within 21 days prior to randomization

- Concurrent use of maintenance bevacizumab

- History of poorly controlled gastrointestinal disorders that could affect the
absorption of study drug (eg, Crohn's disease, ulcerative colitis, etc)

- History (within last 180 days) of significant cardiovascular disease unless the
disease is well-controlled. Significant cardiac disease includes second/third degree
heart block; clinically significant ischemic heart disease; superior vena cava (SVC)
syndrome; poorly controlled hypertension; congestive heart failure of New York Heart
Association (NYHA) Class II or worse (slight limitation of physical activity;
comfortable at rest, but ordinary physical activity results in fatigue, palpitation,
or dyspnea)

- History of arrhythmia (multifocal premature ventricular contractions [PVCs], bigeminy,
trigeminy, ventricular tachycardia, or uncontrolled atrial fibrillation) that is
symptomatic or requires treatment (≥ grade 3), left bundle branch block (LBBB), or
asymptomatic sustained ventricular tachycardia are not allowed. Patients with atrial
fibrillation controlled by medication are not excluded

screening visit ECGs

indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin,
troleandomycin (TAO), or voriconazole

ability to understand or to comply with the requirements of the study or to provide
informed consent

composition to study drug
