Summary

FORT-2 is designed to evaluate safety, efficacy, RP2D and PK of rogaratinib in combination with atezolizumab in patients with untreated FGFR-positive urothelial carcinoma. The study originally comprised two separate parts: Phase 1b (Part A) and Phase 2 (Part B). The study parts differ in design, objectives, and treatment.

The primary objectives of this Phase 1b study (Part A) are to determine the safety, tolerability, RP2D and pharmacokinetics of rogaratinib in combination with atezolizumab in these patients.

The primary objective of the Part B is to compare progression-free survival (PFS) according to RECIST v1.1 of rogaratinib in combination with atezolizumab over placebo in combination with atezolizumab in untreated patients with FGFR-positive locally advanced or metastatic urothelial carcinoma.

Of note, patients who participate in Part A are not allowed to participate in Part B.

Part B will be initiated once the data from Part A supports continuation of the study, even if this occurs prior to primary completion of Part A. The sponsor may decide not to continue the study as a whole after completion of Part A if the data do not support further development.

Part B of the study will no longer be conducted.
