About this study

This is a multiphase, multicenter study, which includes a Phase 1a open-label, dose escalation monotherapy study of ST-067 given as an SC injection with or without obinutuzumab \[Gazyva®\] pre-treatment, by IV infusion, and in combination with pembrolizumab. A Phase 2 monotherapy arm is also planned; the exact design of the Phase 2 study elements with respect to formulation and pre-treatment will be determined after completion of the Phase 1 study portion of the trial.
