Panel is Split on UroGen’s Bladder Cancer Drug
FDA’s Oncologic Drugs Advisory Committee 5/21 was split (4 yes votes to 5 no votes) in its voting on whether UroGen Pharma’s NDA for mitomycin intravesical solution demonstrated a favorable benefit-risk profile for treating adult patients with low-grade intermediate-risk non-muscle invasive bladder cancer. Case Western Reserve Cancer Center oncologist Daniel Spratt voted no and said that without a full randomized trial it is hard to determine mitomycin’s true benefit, adding that there was very limited long-term follow-up.
In voting yes, National Cancer Institute Urologic Oncology Branch associate director Mark Ball acknowledged that a fully enrolled, randomized clinical trial would have mitigated many critiques of mitomycin’s benefit-risk profile. Regardless, he said the company’s data demonstrated efficacy at three months, and that a nonsurgical intervention to treat this disease state and that the signal at 12 months and beyond, even though there are differences in the interpretation of the data, was quite encouraging.
