Study Endpoints

Primary Endpoints

Maximum Tolerated Dose (MTD) and/or the Recommended Dose (RD) for Dose Expansion of ALT-801 in Combination With Cisplatin and Gemcitabine or ALT-801 in Combination With Gemcitabine Alone
8 weeks
Number of Participants With Adverse Events
8 weeks

Number of AEs that occur or worsen after the first dose of study treatment

Objective Response Rate in Treated Patients
12 weeks

Objective response rate (ORR) is defined as confirmed complete response (CR) or partial response (PR) using Response Evaluation Criteria in Solid Tumors \[RECIST V1.0\]: a complete response is the disappearance of all target lesions; a partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. ORR = CR + PR.

To evaluate the safety of the ALT-801-Cisplatin regimen.
12 months
To assess the objective response (OR) which includes CR and PR.
3 months
To assess the clinical benefit (CB) of the ALT-801-Cisplatin regimen which includes CR, PR and SD.
3 months
To determine the MTD of the ALT-801-Cisplatin regimen.
