- High FGFR1 or 3 mRNA expression levels (RNAscope score of 3+ or 4+) in archival or
fresh tumor biopsy specimen

For patients who received prior adjuvant/neoadjuvant chemotherapy or chemo-radiation
for urothelial carcinoma, a treatment-free interval > 12 months between the last
treatment administration and the date of recurrence is required in order to be
considered treatment-naïve in the metastatic setting. Prior local intra-vesical

frequencies in at least one ear.
- Grade ≥ 2 peripheral neuropathy (i.e. sensory alteration or paresthesia including
- Eastern Cooperative Oncology Group Performance Status (ECOG PS) 0 or 1.

- Myocardial infarction (MI) within past 6 months before the first study drug
- Unstable cardiac arrhythmias requiring anti-arrhythmic therapy.
- Patients with known coronary artery disease, congestive heart failure not meeting the
above criteria, or known left ventricular ejection fraction < 50% must be on a stable
medical regimen that is optimized in the opinion of the treating physician, in
consultation with a cardiologist if appropriate.
- Current diagnosis of any retinal disorders including retinal detachment, retinal
pigment epithelial detachment (RPED), serous retinopathy or retinal vein occlusion.
- Current evidence of endocrine alteration of calcium phosphate homeostasis (e.g.
parathyroid disorder, history of parathyroidectomy, tumor lysis, tumoral calcinosis,
- Concomitant therapies that are known to increase serum calcium or phosphate levels
(i.e. antacids, phosphate-containing laxatives oral/rectal, potassium phosphate) and
that cannot be discontinued or switched to a different medication before the first
study drug administration
- Treatment with systemic corticosteroids or other systemic immunosuppressant
medications within 2 weeks before the first study drug administration, or anticipated
requirement for systemic immunosuppressive medications during the trial.
