Study Design
Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: ALT-803
Type: Biological
Overall Status
This is a Phase Ib/II, open-label, dose-finding, multicenter study of intravesical BCG plus ALT-803 in BCG-naive Non-muscle invasive bladder cancer.
Detailed Description
The purpose of this study is to evaluate the safety, identify the Maximum Tolerated Dose (MTD) of ALT-803 and determine the Recommended Dose (RD) level of ALT-803 combined with BCG in patients who have BCG-naive nonmuscle invasive bladder cancer. The anti-tumor activity of BCG+ALT-803 will also be assessed. In addition, the study will characterize the molecular, immunogenicity and pharmacokinetic profile of BCG+ALT-803.

The study includes a dose escalation phase (Phase Ib) and a dose expansion phase (Phase II). The dose escalation phase is concluded when the MTD is determined. A dose level (RD) will be designated for the expansion phase of the study. The expansion phase consists of a noncomparative randomized design of patients receiving ALT-803 at the RD level in combination with BCG or BCG alone.
