A Phase II Randomized Study of Nab-paclitaxel With Gemcitabine at Two Different Dose Combinations to Determine Efficacy in Patients With Advanced Non- Squamous Non-small Cell Lung Cancer (NSCLC).

Phase II study to determine progression free survival (PFS) of nab-paclitaxel administered
in combination with gemcitabine, at two different dose combinations as first line therapy in
patients with unresectable stage IIIB/stage IV non-squamous non-small cell lung cancer
(NSCLC).

This study is designed determine progression free survival (PFS) of nab-paclitaxel
administered in combination with gemcitabine at two different dose combinations in patients
with unresectable stage IIIB/stage IV non-squamous non-small cell lung cancer (NSCLC). Two
dosing strategies of the nab-paclitaxel plus gemcitabine combination will be compared for
efficacy and tolerability. One arm will combine both agents at their current Food and Drug
Administration (FDA) approved doses for the indication of non-small cell lung cancer
(NSCLC). This arm will utilize gemcitabine 1250 mg/m2 IV day 1 and day 8 (FDA approved dose
in combination with cisplatin) combined with nab-paclitaxel 100 mg/m2 IV day 1, 8 and 15
every 21 days (FDA approved dose in combination with carboplatin). The second arm will
utilize the drugs at doses that are approved by the FDA when combined with one another in
metastatic pancreatic adenocarcinoma. This arm will consist of gemcitabine 1000 mg/m2 IV day
1, 8 and 15 combined with nab-paclitaxel at 125 mg/m2 IV day 1, 8 and 15 every 28 days.
Patients will be randomized equally to the two treatment arms. Primary objective is to
assess progression-free survival (PFS). Toxicity assessment, response and overall survival
are secondary endpoints. Statistical power is based on the comparison to historical control
within each treatment arm. In particular, a sample size of 23 patients in each arm will have
84% power to differentiate the 3-month PFS of 30% (null hypothesis) versus 60% (alternative)
based on a 2-sided test at a significance level of 0.05. There will be a lead-in phase to
this trial for each treatment arm with a cohort size of 3 and a maximum of 6 patients.

Inclusion Criteria:

- Patients with histologically proven newly diagnosed stage IV or stage IIIB
non-squamous Non-small Cell Lung Cancer (NSCLC) - Recurrent advanced NSCLC will be
allowed if they have never received chemotherapy for metastatic disease. - Prior
adjuvant chemotherapy will be allowed, if recurrence occurred ≥ 6 months after last
treatment

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

- Measurable disease as per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1

- Washout period of 4 weeks for chemo/radiation/experimental agents

- Resolution of all toxicities to < grade 2 prior to starting treatment (excluding
alopecia)

- Patients must have < Grade 2 pre-existing peripheral neuropathy (per CTCAE)

- Adequate hepatic, renal, and bone marrow functions

- Women of childbearing potential and sexually active males must use an effective
contraception method during treatment and for three months after completing treatment

- Negative serum or urine β-hCG pregnancy test at screening for patients of
childbearing potential

Exclusion Criteria:

- Patient with New York Heart Association class III or IV heart failure

- Women of child bearing potential (WOCBP) are not currently pregnant or breast-feeding

- Co-existing malignancy or malignancies diagnosed within the last 3 years with the
exception of basal cell carcinoma

- Previous anaphylactic or severe allergic reaction to paclitaxel and/or docetaxel will
be excluded

- Grade ≥2 peripheral neuropathy at baseline assessment from any cause

- Symptomatic brain metastases will be excluded. Treated Brain metastases will be
allowed that are neurologically stable.

- Patients with adenocarcinoma with activating EGFR mutation (exon 19 deletions /
insertions, exon 21 point mutations) or EML4-ALK translocation are excluded unless
they are ineligible for epidermal growth factor receptor (EGFR) or ALK targeting
agents.

- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements.
