With cancer, time matters.

Designated an FDA Breakthrough Therapy for Non-Muscle Invasive Bladder Cancer, the novel immunotherapy ANKTIVA® activates key killer cells of the body’s natural immune system to attack the bladder cancer, leading to a long-duration of complete response that for some patients exceeds 47 months.1

ANKTIVA is a potent immunostimulant that unlocks anti-tumor activity and promotes a durable, complete response.

ANKTIVA works by activating the body’s natural immune system to fight disease and provide long-term immune memory against the cancer.

Patient Stories

Read about patients who participated in the clinical trials for ANKTIVA.

Irv's Journey

He was first diagnosed with bladder cancer in 2016 when on Thanksgiving day he had very concerning symptoms, including blood in his urine, and several tumors on the interior surface of his bladder were removed by his local urologist, who treated him with BCG, but he failed to respond and the tumors came back. He was afraid he was going to lose his bladder.

WARNINGS AND PRECAUTIONS: Delaying cystectomy can lead to the development of metastatic bladder cancer, which can be lethal.


DOSAGE AND ADMINISTRATION: For lntravesical Use Only. Instill intravesically only after dilution. Total time from vial puncture to the completion of the intravesical instillation should not exceed 2 hours.

USE IN SPECIFIC POPULATIONS: Pregnancy: May cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception.

ADVERSE REACTIONS: The most common (≥15%) adverse reactions, including laboratory test abnormalities, are increased creatinine, dysuria, hematuria, urinary frequency, micturition urgency, urinary tract infection, increased potassium, musculoskeletal pain, chills and pyrexia.
