|Stage IA Non-Small Cell Lung Carcinoma Stage IB Non-Small Cell Lung Carcinoma||Biological: Fresolimumab Other: Pharmacological Study Radiation: Stereotactic Body Radiation Therapy||Phase 1 Phase 2|
Phase 1: Evaluate the safe dose of fresolimumab in combination with stereotactic ablative radiotherapy (SABR) in patients.
Phase 2. Evaluate the rate of radiation induced pulmonary fibrosis after SABR plus fresolimumab.
I. Evaluate potential adverse events in patients receiving fresolimumab plus SABR. (Phase I) II. Evaluate post treatment changes in pulmonary function. (Phase I) III. Evaluate recurrence rates and progression free survival. (Phase I) IV. Assess pharmacokinetics (PK) of fresolimumab in combination with SABR (optional for patient). (Phase I) V. Evaluate the rate and severity of radiation induced pulmonary fibrosis after SABR plus fresolimumab. (Phase I) VI. Evaluate the severity of radiation induced pulmonary fibrosis after SABR plus fresolimumab. (Phase II) VII. Evaluate potential adverse events in patients receiving fresolimumab plus SABR. (Phase II) VIII. Evaluate post treatment changes in pulmonary function. (Phase II) IX. Evaluate recurrence rates and progression free survival. (Phase II)
OUTLINE: This is a phase I, dose escalation study of fresolimumab followed by a phase II study.
Patients receive fresolimumab intravenously (IV) on days 1, 15, and 36 and undergo SABR in 4 fractions between days 8 and 12.
After completion of study treatment, patients are followed up at 3, 6, and 12 months.

Experimental: Treatment (fresolimumab, SABR)
In Phase 1: Patients receive fresolimumab IV on days 1, 15, and 36 and undergo SABR in 4 fractions between days 8 and 12 in total of 5 subjects. In Phase 2: . Fresolimumab will be administered IV at the dose selected in the preceding Phase 1 on Days 1, 15 and 36 and SABR will be administered in 4 fractions between Days 8 and 12.
Other: Pharmacological Study
Radiation: Stereotactic Body Radiation Therapy
Other Name: SBRT
- Dose limiting toxicities (DLTs) of fresolimumab when combined with SABR defined as Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher radiation pneumonitis or bronchopulmonary hemorrhage (Phase I) [ Time Frame: Up to 30 days ]
Dose limiting toxicity (DLT) is defined as the following grade 3; 4; or 5 CTCAE v4 events determined to be of possibly; probably; of definite relationship to treatment; occurring after 1st dose of fresolimumab and up to 30 days after the last dose of fresolimumab:
- Radiation pneumonitis, or
- Bronchopulmonary hemorrhage A safe dose of fresolimumab is reached when =< 10% of the patients receiving fresolimumab plus SABR develop DLTs.
- Presence of late radiation induced fibrosis (Phase II) [ Time Frame: Up to 12 months ]
