EU CTIS ID: 2023-510306-40-00
What this study is testing
Cohort 1 only: -To evaluate RFS in subjects treated with erdafitinib vs Investigator's Choice, for subjects with high-risk NMIBC who harbor FGFR mutations or fusions, and who recurred after BCG therapy
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- 1. ≥18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place).
- 10.Criterion modified per Amendment 2 10.1. Contraceptive use by men or women should be consistent with local regulations regarding the use of contraceptive methods for subjects participating in clinical studies. a. For women of childbearing potential (defined as: fertile, following menarche and until becoming postmenopausal unless permanently sterile) -> see protocol b. For men who are sexually active with women of childbearing potential: -> see protocol
- 2. Histologically confirmed, recurrent, non-muscle-invasive urothelial carcinoma of the bladder. a. Histopathology: any urothelial cell carcinoma (UCC) variant (ie, UCC with squamous and/or glandular differentiation, micropapillary, nested, plasmacytoid, neuroendocrine, sarcomatoid) are allowed. Presence of any lymphovascular invasion (LVI) will be considered as evidence of high risk. b.Papillary disease (Cohort 1) must be high-risk disease, defined highgrade disease Ta/T1 lesion. Additionally, subjects must have all visible tumor resected completely prior to randomization and documented at baseline cystoscopy. Negative cytology for high-grade urothelial carcinoma is required before randomization. c.CIS (Cohort 2) is not expected to be completely excised, but concurrent papillary disease must be completely excised before enrollment and documented at baseline cystoscopy. Urine cytology is not expected to be negative for malignant cells. d.Marker Lesion (Cohort 3) must have recurrent intermediate-risk disease with all previous tumors being low grade (G1-G2), Ta or T1, and no previous CIS. Additionally, subjects must have a risk of progression less than 5% in the next 2 yrs and a risk of recurrence greater than 50%, calculated using the EORTC risk calculator. All tumors must be removed except for a single untouched 5 to 10 mm lesion (Marker Lesion).

You likely can't join if

Criterion modified per Amendment 2 12.1 Severe hypocalcemia (corrected serum calcium of <7 mg/dl), acute and unhealed bone fractures, known underlying bone disease, or at an increased risk of bone fracture. In addition,any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subjects (eg, compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments. Examples include ongoing active infection requiring systemic therapy and uncontrolled ongoing medical conditions.
- 13. Criterion deleted per Amendment 3
- 14.Criterion added per Amendment 2 As determined by the investigator, contraindications to the use of gemcitabine or MMC/hyperthermic MMC (Cohort 1) per local prescribing information
