Measuring Biomarker Response to AMP-514 in Blood Samples From Patients With Solid Tumors Undergoing Radiotherapy

PRIMARY OBJECTIVES:

I. To evaluate the in-vitro effect of AMP-514, a programmed cell death 1 (PD-1) inhibitor, on
peripheral blood T cell proliferation and cytokine production from patients with solid
malignancies, treated with radiotherapy (RT).

OUTLINE:

Patients undergo blood sample collection at baseline, during the second week of RT, at the
end of RT, and at 1 month after the end of RT.

Inclusion Criteria:

1. Patients 18 years of age or older

2. Histological diagnosis of any solid malignancies and candidates to be treated with RT
(with or without chemotherapy). Patients who have synchronous primary solid
malignancies are eligible. When the risks associated with the diagnostic procedure are
very high, due to different clinical reasons (e.g., severe chronic obstructive lung
disease [COPD] when a CT-guided biopsy is associated with a very high risk of
pneumothorax), and a biopsy is not feasible, then the patient may be enrolled to the
study as per PI judgment.

3. ECOG performance status score of 0-3.

4. Life expectancy of 3 months or longer.

5. Patients able to provide a written informed consent prior to study entry.

Exclusion Criteria:

1. Patients with contraindication to RT.

2. Major surgery within 1 month of starting the study treatment.

3. Prior chemotherapy or radiotherapy for their solid malignancies.

4. Known human immunodeficiency virus (HIV) infection or acquired immunodeficiency
syndrome (AIDS)-related illness or other active infection.

5. Active infection with hepatitis B or hepatitis C (blood testing is not required for
purpose of eligibility).

6. Patients are excluded if they have a history of any other malignancy from which the
patient has been disease-free for less than 2 years, with the exception of adequately
treated basal or squamous cell carcinoma of skin, superficial bladder cancer or
carcinoma in situ of cervix, AJCC (version 7.0) stage 0 or I breast cancer, AJCC
(version 7.0) stage I, or II prostate cancer.

7. Patients are excluded if they have a history of autoimmune disease, as follows:
Patients with a history of inflammatory bowel disease are excluded from this study as
are patients with a history of symptomatic disease (e.g., rheumatoid arthritis,
systemic progressive sclerosis [scleroderma], Systemic Lupus Erythematosus, autoimmune
vasculitis [e.g., Wegener's Granulomatosis]). Patients with motor neuropathy
considered of autoimmune origin (e.g., Guillain-Barre Syndrome and Myasthenia Gravis)
are excluded. Patients with a history of autoimmune thyroiditis are eligible if their
current thyroid disorder is treated and stable with replacement or other medical
therapy.

8. Other severe acute or chronic medical or psychiatric condition that may increase the
risk associated with study participation and in the judgment of the investigator would
make the subject inappropriate for entry into this study.
