Study terminated due to withdrawal of pharmaceutical funding

Pemetrexed is approved for second line therapy in metastatic NSCLC. Given the single-agent activity of pemetrexed and the tolerability of pemetrexed in combination with radiation, this study will evaluate survival rates and toxicities in patients with poor risk stage III NSCLC.

OUTLINE: This is a multi-center study.

• Pemetrexed (Alimta) 500mg/m2 administered intravenously over approximately 10-minutes on Day 1 of a 21-day cycle x 3 cycles
• Radiation will start between days -1 to 2 from day 1 of cycle 1. Day 1 radiotherapy must be a Monday, Tuesday, or Wednesday.

The planned radiation dose is 60 Gy in 2.0 Gy fractions. The entire PTV, including primary tumor and areas of known nodal disease, shall receive 60 Gy at 2.0 Gy fractions, 5 fractions/week for 30 fractions over 6 weeks.

Performance Status: ECOG performance status 2

Life Expectancy: Not specified

Hematopoietic:

• Platelets ≥ 100 K/mm3
• Absolute Neutrophil Count (ANC) ≥ 2.0 K/mm3

Hepatic:

• Aspartate transaminase (AST) ≤ 2.5 x ULN.
• Alanine transaminase (ALT) ≤ 2.5 x ULN.
• Total bilirubin ≤ 1.5 x ULN

Renal:

• Calculated creatinine clearance (using Cockcroft-Gault formula) ≥ 45 cc/min

Cardiovascular:

• No significant history of cardiac disease. Must not have unstable angina (anginal symptoms at rest).

Pulmonary:

• Forced expiratory volume in 1 second (FEV1) greater than 1L

Inclusion Criteria:

• Histological or cytological proof of Non Small Cell Lung Cancer (NSCLC)
• Measurable or non-measurable disease per RECIST as evaluated by imaging within 28 days prior to registration for protocol therapy
• Unresectable Stage IIIA or IIIB disease as evaluated by imaging within 28 days prior to registration for protocol therapy
• Weight loss of greater than 10% in the preceding six months prior to registration for protocol therapy.
• Serum albumin < 0.85 x institutional lower limit of normal
• Able and willing to interrupt non-steroidal anti-inflammatory agents for 2 days before (5 days for long acting agents such as piroxicam), the day of, and 2 days following administration of pemetrexed
• Lung V20 < 35% within 14 days prior to registration for protocol therapy, as planned by the radiation oncologist
• Mean lung dose < 20 Gy within 14 days prior to registration for protocol therapy, as planned by the radiation oncologist
• Written informed consent and HIPAA authorization for release of personal health information
• Age ≥ 18 years
• Females of childbearing potential and males must be willing to use an effective method of contraception (hormonal or barrier method of birth control; abstinence) from the time of consent until at least 90 days following completion of study treatment.
• Females of childbearing potential must have a negative pregnancy test within 7 days prior to registration for protocol therapy. Patients are considered not of child bearing potential if they are surgically sterile (they have undergone a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or they are postmenopausal.

Exclusion Criteria:

• Patients with malignant pleural effusions are not eligible. The only exception is a patient with a pleural effusion visible only on CT scan (and not visible on CXR) OR deemed too small to tap.• No CNS metastases. All patients must undergo a CT scan/MRI of the brain within 28 days prior to registration for protocol therapy to exclude brain metastasis.
• No prior chemotherapy, adjuvant therapy or radiotherapy for lung cancer.
• No metastatic disease as determined by PET scan within 28 days prior to registration for protocol therapy.
• No active clinically serious infections as judged by the treating investigator (> CTC v3, Grade 2) including known human immunodeficiency virus (HIV) infection or chronic Hepatitis B or C.
• No other active malignancies.
• No history of collagen vascular disease (CVD).
• No significant history of cardiac disease. Must not have unstable angina (anginal symptoms at rest).
• No history of psychiatric illness/social situations that would limit compliance with study requirements.
• Females must not be breastfeeding.
