Study Groups

durvalumab and tremelimumab plus Radiotherapy (RT)

Patients will receive 1500 mg durvalumab via IV infusion q4w for up to 4 doses/cycles and 75 mg tremelimumab via IV infusion q4w for up to 4 doses/cycles, and then continue 1500 mg durvalumab q4w starting on Week 16. Tremelimumab will be administered first. Durvalumab infusion will start approximately 1 hour after the end of tremelimumab infusion. The duration will be approximately 1 hour for each infusion. Radiotherapy (RT) will be performed using external beam ionizing radiation as standard therapy in accordance with institutional standard practice. RT will be initiated within 7 days after the first of durvalumab and tremelimumab.

Tremelimumab will be administered first. Durvalumab infusion will start approximately 1 hour after the end of tremelimumab infusion. The duration will be approximately 1 hour for each infusion. The ablation will be performed percutaneously under image guidance as standard therapy at the discretion of the interventional radiologist in accordance with institutional standard practice. Ablation will be performed within 7 days after the first of durvalumab and tremelimumab.

• At least one tumor for which palliative RT is considered appropriate standard therapy (cohort 1); or, at least one tumor for which palliative ablation is considered appropriate standard therapy (cohort 2).
• At least one index lesion that will not undergo RT or ablation, and which is measurable based on RECIST 1.1.
• Be ≥ 18 years of age on day of signing informed consent.

• Consent for use of available archived tissue and tumor obtained during a standard procedure, for research purposes.
• Have a performance status of 0 or 1 on the ECOG Performance Scale.
• Female subjects must either be of non-reproductive potential (i.e., post-menopausal by history: ≥60 years old and no menses for ≥ 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test within 2 weeks prior to starting treatment.
• Demonstrate adequate organ function as defined all screening labs should be performed within 4 weeks prior to treatment initiation.

• Hemoglobin ≥ 8.0 g/dL
• Absolute neutrophil count (ANC) ≥1,500 /mcL
• Platelets ≥100,000 / mcL
• Serum creatinine ≤1.5 X upper limit of normal (ULN) OR
• Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) OR
• Serum creatinine CL>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance.
