Inclusion Criteria

1. Histologically or cytologically confirmed Stage IIIB/ IV NSCLC.
2. Relapsed after treatment with 1 or 2 prior chemotherapy regimens, at least 1 of which must have been a platinum-based treatment. Patients may have received pemetrexed as 1 of the prior therapies. Patients may not have received neoadjuvant/adjuvant chemotherapy or investigational therapy as their only prior therapy.
3. Recovered from the toxic effects of prior therapy.
4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
5. Smoked = 100 cigarettes in their lifetime, whether a former or current cigarette
smoker.
6. = 18 years of age.
7. Adequate hematologic, hepatic, and renal function as defined by: white blood
cell (WBC) count = 2500 cells/µL (= 2.5 x 109 cells/L); absolute neutrophil
count (ANC) = 1500 cells/µL (= 1.5 x 109 cells/L); platelet count = 100,000/µL;
calculated creatinine clearance of = 50 mL/min; total bilirubin = 1.5 x the upper
limit of normal (ULN); and aspartate aminotransferase (AST, serum glutamicoxaloacetic
transaminase [SGOT]) and alanine aminotransferase (ALT, serum
glutamic-pyruvic transaminase [SGPT]) = 3 x ULN (if clearly attributable to
liver metastases, = 5 x ULN is permitted).
8. The patient has been on a regimen of 1-1.25 mg PO QD of folic acid for at least 7 days prior to randomization and has received 1 mg IM of vitamin B12 within 10 weeks prior to randomization.
9. Women of childbearing potential must be practicing a medically acceptable
contraceptive regimen and must have a negative serum pregnancy test within
14 days prior to randomization. Patients who are postmenopausal for at least
1 year (> 12 months since last menses) or are surgically sterilized do not require
this test.
10. Men who are not surgically sterile must be practicing a medically safe and
effective contraceptive regimen from the time of study randomization, and
agree to continue practicing until at least 90 days after the last administration
of study treatment.
11. Accessible for repeat dosing and follow-up.
12. Given written informed consent (IC).
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years)
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

1. Active concurrent primary malignancy or prior malignancies occurring within 5 years (except non-melanoma skin cancer or in situ carcinoma of the cervix). If there is
a history of prior malignancies other than those exceptions listed above, the patient must be disease-free for = 5 years. Patients with other prior malignancies less than 5 years before study entry may still be enrolled if they have received treatment resulting in complete resolution of the cancer and currently have no clinical, radiologic, or laboratory evidence of active or recurrent disease.
2. Use of any investigational drugs, biologics, or devices within 4 weeks prior to
randomization.
3. Previous exposure to pralatrexate or erlotinib.
4. Women who are pregnant or breastfeeding.
5. Congestive Heart Failure Class III/IV according to New York Heart Association
(NYHA) Functional Classification.
6. Uncontrolled hypertension.
7. Human immunodeficiency virus (HIV)-positive diagnosis with a CD4 count of < 100 mm3 or detectable viral load within the past 3 months, and is receiving combination anti-retroviral therapy.
8. Symptomatic central nervous system (CNS) metastases or lesions for which
treatment is required.
9. Major surgery within 2 weeks of study randomization.
10. Receipt of any conventional systemic chemotherapy within 4 weeks (6 weeks
for nitrosoureas, mitomycin C), or RT within 2 weeks, prior to randomization.
11. Active infection or any serious underlying medical condition, which would
impair the ability of the patient to receive protocol treatment.
12. Dementia or significantly altered mental status that would prohibit the
understanding and giving of informed consent or limit study compliance.
