Drug Hexaminolevulinate (Hexvix)

Each patient enrolled into the study will be infused with 50 mL of a 2 mg/mL Hexvix solution in the bladder using a catheter. Subsequently, after fluid retention by the patient in the bladder for one hour, the bladder will be emptied.

Population

Patients with documented or suspected bladder cancer.

Criteria

Inclusion Criteria:

Patients over 18 years of age.
Patients of either sex.
Patients with documented or highly suspected non-invasive bladder cancer.

Exclusion Criteria:

Patients with hypersensitivity to the drug substance or any excipient of Hexvix.
Patients with porphyry.
Women of childbearing age.
Patients at a high risk of suffering extensive bladder inflammation e.g. patients after intravesical BCG treatment, patients with moderate or severe leukocyturia or patients undergoing recent bladder surgery.
