ADSTILADRIN Offers a Unique Way
to Treat NMIBC as a Monotherapy

ADSTILADRIN is a non-replicating adenoviral vector–based gene-mediated immunotherapy

ADSTILADRIN delivers the IFNa2b gene to bladder urothelial cells 1

ADSTILADRIN (nadofaragene firadenovec-vncg) is a non-replicating adenoviral vector that delivers the human interferon alpha 2B (IFNα2b) gene to bladder urothelial cells.1

ADSTILADRIN travels to cell nucleus to deliver the INFa2b gene 2

Once inside the bladder, ADSTILADRIN penetrates the bladder urothelial cells and travels to the cell nucleus to deliver the IFNα2b gene.1

Cells in the bladder that have taken up ADSTILADRIN begin to produce IFNa2b 3

Both normal urothelial and tumor cells in the bladder that have taken up ADSTILADRIN begin to produce and secrete high and transient local expression of IFNα2b, a naturally occurring cytokine.1,2

IFNα2b has antitumor activity and enhances the body’s
natural ability to fight cancer1,2

ADSTILADRIN Is a Localized Treatment for Localized Tumors

ADSTILADRIN is a non-replicating, vector-based gene therapy that works with the patient’s own immune system to fight bladder cancer. It delivers the IFNα2b gene to bladder urothelial cells. It does not alter any existing genes in the body like some other gene therapies.1

The bladder is an ideal organ for gene therapy

Key reasons the bladder is ideal for this type of therapy:

  • Direct contact between the gene vector and tumor cells3,4
  • Local administration limiting systemic exposure4
  • Easy access to monitor effects of therapy5

Gene therapy helps fight cancer by:

  • Bolstering an immune response5,6
  • Protecting healthy cells from the side effects of these treatments5

Abbreviation: NMIBC, non–muscle-invasive bladder cancer.

Important Safety Information


ADSTILADRIN is a non-replicating adenoviral vector-based gene therapy indicated for the treatment of adult patients with high-risk Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors.


CONTRAINDICATIONS: ADSTILADRIN is contraindicated in patients with prior hypersensitivity reactions to interferon alfa or to any component of the product.


  • Risk with delayed cystectomy: Delaying cystectomy in patients with BCG-unresponsive CIS could lead to 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 3 months or if CIS recurs, consider cystectomy.
  • Risk of disseminated adenovirus infection: Persons who are immunocompromised or immunodeficient may be at risk for disseminated infection from ADSTILADRIN due to low levels of replication-competent adenovirus. Avoid ADSTILADRIN exposure to immunocompromised or immunodeficient individuals.

DOSAGE AND ADMINISTRATION: Administer ADSTILADRIN by intravesical instillation only. ADSTILADRIN is not for intravenous use, topical use, or oral administration.

USE IN SPECIFIC POPULATIONS: Advise females of reproductive potential to use effective contraception during ADSTILADRIN treatment and for 6 months after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during ADSTILADRIN treatment and for 3 months after the last dose.

ADVERSE REACTIONS: The most common (>10%) adverse reactions, including laboratory abnormalities (>15%), were glucose increased, instillation site discharge, triglycerides increased, fatigue, bladder spasm, micturition (urination urgency), creatinine increased, hematuria (blood in urine), phosphate decreased, chills, pyrexia (fever), and dysuria (painful urination).
