<qa>  What is the name of the study that includes a dose expansion phase?This is a Phase IbII, open-label, multi-center, competitive enrollment and dose-escalation study of ALT-801 in a biochemotherapy regimen either containing cisplatin and gemcitabine or containing gemcitabine alone in patients who have muscle invasive or metastatic urothelial cancer of bladder, renal pelvis, ureters and urethra. The purpose of this study is to evaluate the safety, determine the maximum tolerated dose MTD and the recommended dose RD, and assess the anti-tumor response of ALT-801 in combination with cisplatin and gemcitabine or ALT-801 in combination with gemcitabine alone. The pharmacokinetic profile of ALT-801 in combination with cisplatin and gemcitabine will also be assessed. The study includes a dose escalation phase Phase Ib and a dose expansion phase Phase II. Phase II has two treatment groups, Expansion Group 1 and Expansion Group 2. Expansion Group 2 is for platinum-refractory patients, consisting of two treatment arms based on the patients renal function. Patients will enroll to Expansion Group 2 after stage 1 of the Group 1 expansion is complete.
