Clinical Trial Summary

This is a multi-center, stratified and single-blinded Phase 2 study of neoadjuvant immunotherapy in combination with the antiGDF15 antibody visugromab (CTL-002) for the treatment of subjects with MIBC set to undergo radical Cystectomy (RC) who cannot receive or refuse to receive cisplatin-based chemotherapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Evaluation of immune cell abundance by density (positive cells/mm2 of tumor) in tumor tissue		min. 3 months
Other	Evaluation of selected cytokine concentration in peripheral blood		min. 3 months
Other	Evaluation of selected chemokine concentration in peripheral blood		min. 3 months
Other	Assessment of molecular profile	Examples: Analysis of tumor mutational burden (TMB) defined as the number of somatic mutations per megabase of interrogated genomic sequences.; Analysis of differential gene expression as fold change of target gene expression in a target sample relative to a reference sample, normalized to a reference gene	min. 3 months
Primary	Pathologic complete response rate	Rate of subjects with no viable tumor cells in Radical Cystectomy Resection	min. 3 months
Primary	Radiologic response rate according RECIST	RECIST 1.1 prior Radical Cystectomy	min. 3 months
Secondary	Adverse Events	Incidence of treatment emergent adverse events	min. 4 months
Secondary	Treatment related delay of surgery	Treatment related delay of Radical Cystectomy > 8 weeks after last dose of study	min. 4 months
Secondary	Cmax following the first dose of Visugromab (CTL-002)	PK parameter from serum Visugromab (CTL-002) levels	1 day
Secondary	AUC following the first dose of Visugromab (CTL-002)	PK parameter from serum Visugromab (CTL-002) levels	14 days
Secondary	Half-life of Visugromab (CTL-002)	PK parameter from serum Visugromab (CTL-002) levels	min. 3 months
Secondary	GDF-15 serum levels	Measurement of concentration in peripheral blood	1 day
Secondary	Evaluation of tumor stage downgrading from baseline to Radical Cystectomy		min. 3 months
Secondary	Evaluation of EFS (Event-free Survival)	Event-free survival will be defined as the time from first study drug administration to one of the following: Radiographic disease progression precluding a curative intent surgery per RECIST v1.1 prior to RC; Initiation of neoadjuvant chemotherapy preceding RC as per Investigator decision; Inability to undergo RC due to the onset of treatment-related side effects; Inability to complete a curative intent surgery determined by the urologist at the time of RC (e.g., unresectable tumor, metastases discovered at RC); Local or distant recurrence assessed by cross-sectional imaging and/or biopsy after RC; Death from any cause. In this study, subject refusal to undergo RC due to the evidence of complete or near-complete clinical response (assessed on cross-sectional imaging as previously described) will not be considered an event.	12 months after Radical Cystectomy
Secondary	OS (Overall Survival)	Overall survival is defined as the time from the first study drug administration to the date of death, regardless of the cause of death.; Subjects who were alive at the time of the analysis will be censored at the date the subject was last known to be alive.	15 months
