Eribulin Mesylate in Combination With Intermittent Erlotinib in Patients With Previously Treated, Advanced Non-Small Cell Lung Cancer

Inclusion criteria:

- Histologically confirmed non-small cell lung cancer (NSCLC)

- At least one prior platinum-based doublet anti-cancer treatment for recurrent or
advanced NSCLC

- Disease progression during or after the last anti-cancer therapy

- Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2

- Serum creatinine less than or equal to 2.0 mg/dL or creatinine clearance 40 mL/min
according to Cockcroft and Gault formula:

- Absolute neutrophil count greater than or equal to 1.5 x 10^9/L, hemoglobin greater
than or equal to 10 g/dL (can be corrected by growth factor or transfusion), and
platelet count greater than or equal to 100 x 10^9/L

- Total bilirubin less than or equal to 1.5 times the upper limit of normal (ULN) and
alkaline phosphatase (AP), alanine aminotransferase (ALT), and aspartate
aminotransferase (AST) less than or equal to 3 times ULN (in the case of liver
metastases less than or equal to 5 times ULN). In case AP is greater than 3 times ULN
(in absence of liver metastases) or greater than 5 times ULN (in presence of liver
metastases) AND subject also is known to have bone metastases, the liver specific AP
must be separated from the total and used to assess the liver function instead of the
total AP.

- At least one lesion of greater than or equal to 1.5 cm in longest diameter for
non-lymph nodes or greater than or equal to 1.5 cm in shortest diameter for lymph
nodes which is serially measurable according to the Response Evaluation Criteria in
Solid Tumors (RECIST) version 1.17

- Males and females, age greater than or equal to 18 years

- Provide written informed consent

- Are willing and able to comply with all aspects of the protocol

- Females of childbearing potential must have a negative serum beta-human chorionic
gonadotropin (Beta-hCG) at Visit 1 (Screening) and a negative urine pregnancy
test prior to starting study drug (Visit 2). Female subjects of childbearing
potential must agree to be abstinent or to use highly effective methods of
contraception (eg, condom + spermicide, condom + diaphragm with spermicide,
intrauterine device (IUD), or have a vasectomised partner) having starting for at
least one menstrual cycle prior to starting study drugs and throughout the entire
study period and for 30 days (longer if appropriate) after the last dose of study
drug. Those women using hormonal contraceptives must also be using an additional
approved method of contraception (as described previously). Perimenopausal women
must be amenorrheic for at least 12 months to be considered of non-childbearing
potential.

- Male subjects who are not abstinent or have not undergone a successful vasectomy, who
are partners of women of childbearing potential must use, or their partners must use a
highly effective method of contraception (eg, condom + spermicide, condom + diaphragm
with spermicide, IUD) starting for at least one menstrual cycle prior to starting
study drugs and throughout the entire study period and for 30 days (longer if
appropriate) after the last dose of study drug. Those with partners using hormonal
contraceptives must also be using an additional approved method of contraception (as
described previously).

Exclusion criteria:

- Prior therapy with eribulin or an tyrosine kinase inhibitor of the epidermal growth
factor receptor

- Subjects with brain or subdural metastases are not eligible, unless they have
completed local therapy and have discontinued steroids for this indication for greater
than or equal to 4 weeks before starting study treatment. Symptoms attributed to brain
metastases must be stable for greater than or equal to 4 weeks before starting study
treatment; radiographic stability should be determined by comparing contrast-enhanced
computed tomography (CT) or magnetic resonance imaging (MRI) brain scan performed
during screening to a prior scan performed 4 weeks earlier.

- Existing anti-cancer therapy-related toxicities of grade greater than or equal to 2,
other than any grade of alopecia or grade less than or equal to 2 neuropathy, which
are acceptable

- Current smokers who will not stop smoking one week prior to treatment and during the
study

- History of congestive heart failure with New York Heart Association (NYHA) Grade
greater than II, unstable angina, myocardial infarction within the past 6 months,
serious cardiac arrhythmia

- Electrocardiogram with QTc interval greater than or equal to 500 msec based upon
Bazett's formula (QTcB)

- Females who are pregnant (positive Beta-hCG test) or breastfeeding

- Subject with hypersensitivity to eribulin and /or erlotinib or any of the excipients

- Presence of a progressive central nervous system (CNS) disease, including degenerative
CNS diseases and progressive tumors

- Subjects who are known to be human immunodeficiency virus (HIV) positive, because the
neutropenia caused by the study treatments may make such subjects particularly
susceptible to infection

- Subjects with active viral hepatitis (A, B, or C) as demonstrated by positive serology

- Radiotherapy, chemotherapy, biological therapy or investigational agents within 2
weeks prior to start of study treatment

- Meningeal carcinomatosis

- History of drug or alcohol dependency or abuse within approximately the last 2 years

- Medically unfit to receive the study drug or unsuitable for any other reason according
to investigator judgment

- Any history of or concomitant medical condition that, in the opinion of the
Investigator, would compromise the subject's ability to safely complete the study

- Major surgery within 4 weeks before starting study treatment or scheduled for surgery
during the projected course of the study
