Sesen Bio Inc. said it is "deeply disappointed" after it received a Complete Response Letter from the U.S. Food and Drug Administration regarding its Biologics License Application for Vicineum.

The company's shares were recently halted.

Sesen previously said it believed it was on track for an decision by Aug. 18 for its Biologics License Application for Vicineum for treatment of BCG-unresponsive non-muscle invasive bladder cancer.

Shares have risen sharply in recent days. Prior to the halt Friday, the stock was up 20% to $5.90.

Sesen said Wednesday that it was expanding its executive leadership team in support of its "continued transformation into a commercial-stage company."

The company said Friday that the FDA provided recommendations specific to additional clinical/statistical data and analyses in addition to Chemistry, Manufacturing and Controls issues pertaining to a recent pre-approval inspection and product quality.

Sesen plans to request a Type A meeting with the FDA as soon as possible.
