A Study of Pemigatinib in Non-muscle Invasive Bladder Cancer Patients With Recurrent Low- or Intermediate-Risk Tumors

Inclusion Criteria:

Prior histologically confirmed low- or intermediate-risk non-muscle invasive urothelial carcinoma of the bladder (NMIBC) defined according to the following characteristics:

Low Risk

Initial tumor with all of the following:
Solitary tumor
Ta tumor
Low-grade
<3 cm
No CIS

Intermediate Risk

--- All tumors not defined in the two adjacent categories (between the category of low- and high-risk)

High Risk

T1 tumor
High-grade
CIS
Multiple and recurrent and large (>3 cm) Ta low-grade tumors (all conditions must be met for this point on Ta low-grade tumors)
Documented tumor recurrence as noted in standard of care follow up cystoscopy.
ECOG (WHO) performance status 0-2
Age ≥ 18 years old

Patients must have the following laboratory values:

White blood cell count (WBC) > 3.0 K/mm3
Absolute neutrophil count (ANC) ≥ 1.5 K/mm3
Platelets ≥ 100 K/mm3
Hemoglobin (Hgb) ≥ 9 g/dL
Serum total bilirubin: ≤ 1.5 x ULN
ALT and AST ≤ 3.0 x ULN
Serum calcium < ULN
Serum phosphate < ULN
Serum creatinine ≤ 1.5 x ULN or serum creatinine > 1.5 - 3 x ULN if calculated creatinine clearance (CrCl) is ≥ 30 mL/min using the modified Cockcroft-Gault equation
Patients who give a written informed consent obtained according to local guidelines

Exclusion Criteria:

Patients with concurrent upper urinary tract (i.e. ureter, renal pelvis) non-invasive urothelial carcinoma.
Patients with high grade urothelial carcinoma on their most recent urine cytology.
Patients with another active second malignancy other than non-melanoma skin cancers and biochemical relapsed prostate cancer. (Patients that have completed all necessary therapy and are considered to be at less than 30% risk of relapse are not considered to have an active second malignancy and are eligible for enrollment.)
Patients who have received the last administration of an anti-cancer therapy including chemotherapy, immunotherapy, and monoclonal antibodies ≤ 4 weeks prior to starting study drug, or who have not recovered from the side effects of such therapy
Patients who have received prior selective fibroblast growth factor receptor targeting agents (i.e. pemigatinib, dovitinib, BGJ398, AZD4547, JNJ-42756493, etc.).
Patients who have had radiotherapy ≤ 4 weeks prior to starting study drug, or who have not recovered from radiotherapy toxicities
Patients who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury ≤ 4 weeks prior to starting study drug, or patients who have had minor procedures (i.e. TURBT), percutaneous biopsies or placement of vascular access device ≤ 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury
