Primary purpose: TREATMENT

Brief summary: The purpose of this study is to treat participants with the combination of durvalumab (the study drug) and proton beam therapy. Proton beam therapy is a type of radiotherapy (RT) with a unique characteristic where the proton stops at a specific depth according to its energy. This may be advantageous in treating lung cancer because it allows for a sufficient tumor dose that may improve local control and survival while sparing normal organs at risk, such as the heart, lung, and spinal cord.

Detailed description: All study participants will receive the same study intervention, which will consist of proton based external beam radiation therapy with concurrent Durvalumab starting one week before RT. Radiation will be delivered using cardiac sparing accelerated fractionated proton radiation. Radiation will have two dose escalation schemes followed by an expansion cohort for a total of approximately 24 participants enrolled at University Hospitals Cleveland Medical Center.

The objectives of this study are to evaluate the safety and feasibility of combination of durvalumab with two different schemes for accelerated fractionation proton radiation in participants who are unable to tolerate concurrent chemoradiation therapy. This will also include the evaluation of adverse events resulting from these treatment schemes.

Creatinine CL (mL/min) = (Weight (kg) x (140 - Age)) / (72 x serum creatinine (mg/dL))

Creatinine CL (mL/min) = (Weight (kg) x (140 - Age)) / (72 x serum creatinine (mg/dL)) x 0.85

* Subjects must have the ability to understand and the willingness to sign a written informed consent document.
* Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal participants. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
* Women \<50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
* Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \>1 year ago, had chemotherapy-induced menopause with last menses \>1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
