Prior treatment

• Patients whose radiation treatment is likely to encompass a volume of whole lung receiving ≥ 20 Gy in total of more than 35% of lung volume.
• Participation in another clinical study with an investigational product with anti-neoplastic activity during the last 3 weeks prior to treatment initiation

• Receipt of live attenuated vaccine within 30 days prior to the first dose of investigational product.
• Prior radiation therapy to the region of the study cancer that would result in overlap of radiation therapy fields.
