Patients must have normal organ and marrow function as defined: leukocytes >/=3,000/mcL, absolute neutrophil count >/=1,500/mcL, platelets >/=100,000/mcL, hemoglobin >/9.0g/dL, total bilirubinallowed if in the setting of known Gilbert's disease), AST(SGOT)/ALT(SGPT)institutional upper limit of normal orAlkaline phosphatasemetastases are present, creatinine clearance >/=50 mL/min/1.73^2 by Cockcroft-Gault equation (creatinine clearance= ([140-age]x body mass)/(plasma creatinine x 72) x gender correction factor) or by 24-hour urine collection.

10. Brain metastases are allowed, as long as they are stable and do not require treatment with anticonvulsants or escalating doses of steroids.

11. Females of childbearing potential must have a negative serum pregnancy test and must agree to use adequate contraception for the duration of the study and six months after. Females of childbearing potential are defined as those who are not surgically sterile (ie, bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or postmenopausal (defined as 12 months with no menses without an alternative medical cause). Continued in #12

12. Continued from #11: a) Acceptable effective methods of contraception for women include implants, injectables, combined oral contraceptives, some intrauterine devices/systems and sterilization including vasectomy of the partner, all being used in combination with barrier methods of contraception (e.g. condoms). b) True sexual abstinence is also an acceptable method of contraception. Continued in #13

13. Continued from #12: Women will be considered post-menopausal if they have been amenorrheic for the past 12 months without an alternative medical cause. The following age-specific requirements must also apply: i.)Women < 50 years old: they would be considered post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of exogenous hormonal treatments. The levels of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) must also be in the post-menopausal range (as per the institution). ii.)Women >/= 50 years old: they would be consider post-menopausal if they have been amenorrheic for the past 12 months or more following cessation of all exogenous hormonal treatments, or have had radiation-induced oophorectomy with the last menses > 1 year ago, or have had chemotherapy-induced menopause with >1 year interval since last menses, or have had surgical sterilisation by either bilateral oophorectomy or hysterectomy.

14. Non-sterilized males who are sexually active with a female partner of childbearing potential must use adequate contraception for the duration of the study and 90 days after the last dose of study medication. a) Acceptable methods of contraception for men include the use of condoms with spermicidal foams/gels or prior vasectomy. b) True sexual abstinence is also an acceptable method of contraception.

15. Ability to understand and the willingness to sign a written informed consent document.

16. Have adequate renal function, with a GFR of >/= 50ml/min by the Cockcroft-Gault formula or by 24 hour urine collection.

Exclusion Criteria:

1. Have received or are receiving an investigational medicinal product (IMP) or other systemic anticancer treatment within 4 weeks prior to the first dose of study treatment, or within a period during which the IMP or systemic anticancer treatment has not been cleared from the body (e.g. a period of 5 'half-lives'), whichever is the most appropriate and as judged by the investigator.

2. Current or prior use of immunosuppressive medication within 14 days of the 1st dose of durvalumab, with the exception of intranasal and inhaled corticosteroids or oral corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid.

3. Any concurrent chemotherapy, immunotherapy, biologic, or hormonal therapy for cancer treatment.
