It was originally launched as Valstar in the U.S. in 1999 for intravesical therapy of Bacille Calmette-Guérin (BCG)-refractory carcinoma in situ of the urinary bladder in patients in whom cystectomy would be associated with unacceptable morbidity or mortality; however, it was voluntarily withdrawn in 2002 due to manufacturing issues.^[2] Valstar was relaunched on September 3, 2009.^[3]
