Why ANKTIVA?

BCG treatment of NMIBC
Bacillus Calmette-Guerin (BCG) is the most commonly-used therapy for non-muscle invasive bladder cancer (NMIBC).1 It eliminates NMIBC in about 60% of people who receive it and has a good safety profile.2,3 BCG is considered an immunotherapy – when delivered to the bladder it associates with the bladder cancer cells, attracting immune cells to the cancer cells and eliminating them.
BCG efficacy requires an effective immune response
A key component in BCG efficacy is the ability of cells of the immune system – specifically natural killer (NK) and T cells – to respond and effectively kill the cancer cells.4,5 In BCG-unresponsive individuals whose cancer does not respond to BCG or in whom the cancer returns after an initial response, it is likely the immune response is inadequate, due to acquired immunoresistance6 or immunosenescence. This is not surprising, given the advanced age of most NMIBC patients and the association of immunosenescence (reduced immune function) with age.7
Why try BCG again?

ANKTIVA restores the necessary immune response to BCG, including establishment of immune memory that leads to durable responses, by proliferating and activating NK and T cells.9,10,11

The interleukin-15 (IL-15) immune-cell activator ANKTIVA® works synergistically with BCG to effectively kill cancer cells, even in BCG-unresponsive NMIBC patients for whom BCG alone was not effective.8

How effective is ANKTIVA plus BCG?

In the pivotal clinical trial, ANKTIVA plus BCG eliminated cancer in more than 62% of patients,12 with BCG-unresponsive bladder carcinoma in situ (CIS) with or without Ta/T1 papillary disease. These responses are typically durable, lasting more than a year in a majority of patients and more than 4 years in some patients, with many responses ongoing to date. Critically, these responses are associated with avoidance of cystectomy in about 90% of responders.8

In the key clinical study QUILT 3.032, the response rate with ANKTIVA plus BCG was higher than that for other approved therapies for BCG-unresponsive bladder CIS, including both gene therapy or checkpoint inhibitor therapy.13

What is the practical advantage of ANKTIVA plus BCG?

The combination therapy is easily prepared before use and does not require extended thawing time, preventing waste, and is delivered following the familiar method and schedule as used for BCG alone.12

Because ANKTIVA is an intravesical therapy delivered directly to the bladder, the risk of systemic adverse reactions that occur with immunotherapies that have to be delivered by injection is very low. Thus, all the advantages of BCG therapy can be leveraged, with the increased efficacy provided by ANKTIVA, even in BCG-unresponsive patients.

Irv’s Journey

Irv’s Journey

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

Wayne’s Journey

Wayne’s Journey

Wayne has lived a rich life with his wife, two daughters, and three grandchildren. He describes himself as someone who “just likes people”. When he was first told, “you might have a tumor in your bladder”, he became very concerned, especially when he learned his first treatment with BCG wasn’t working. Wayne feels lucky that a friend told him about a clinical trial for patients like himself who were not cured by BCG alone.

Indication and Important Safety Information

INDICATION AND USAGE

ANKTIVA is an interleukin-15 (IL-15) receptor agonist indicated with Bacillus Calmette-Guerin (BCG) for the treatment of adult patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors.

WARNINGS AND PRECAUTIONS

Risk of Metastatic Bladder Cancer with Delayed Cystectomy. Delaying cystectomy can lead to the development of muscle invasive or metastatic bladder cancer, which can be lethal. If patients with CIS do not have a complete response to treatment after a second induction course of ANKTIVA with BCG, reconsider cystectomy.

DOSAGE AND ADMINISTRATION

For lntravesical Use Only. Do not administer by subcutaneous or intravenous routes. 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.
