Mean QT interval corrected for heart rate (QTc) ≥470 ms calculated from 3 electrocardiograms (ECGs) using Frediricia's Correction~5. Current or prior use of immunosuppressive medication within 28 days before the first dose of MEDI4736, with the exceptions of 10 mg dexamethasone prior to paclitaxel infusion and intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid~6.

Known history of previous clinical diagnosis of tuberculosis~12. History of leptomeningeal carcinomatosis~13. Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days of receiving MEDI4736~14. Female subjects who are pregnant, breast-feeding or male or female patients of reproductive potential who are not employing an effective method of birth control~15. Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results~16. Symptomatic or uncontrolled brain metastases requiring concurrent treatment, inclusive of but not limited to surgery, radiation and/or corticosteroids.~17. Subjects with uncontrolled seizures.

Study Arms:
- Durvalumab and Paclitaxel (Type: EXPERIMENTAL): After one cycle of paclitaxel, durvalumab will be given concurrently with paclitaxel. Once paclitaxel cycles are completed, durvalumab will be continued alone until disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
