Indication & Patient Population

  • BCG unresponsive, non-muscle invasive bladder cancer (NMIBC) with carcinoma in situ (CIS) with or without papillary tumors

Prior Therapy Requirements

  • Documented BCG unresponsiveness
  • Within 12 months of last dose of BCG

Dosage & Administration

  • Intravesical instillation: 225 mg once every 3 weeks for up to 8 doses (6 months)
  • Followed by 225 mg once every 12 weeks for up to 6 doses (18 months), or until persistent/recurrent NMIBC, disease progression, or unacceptable toxicity
  • Implant must be inserted into the bladder via urinary catheter and stylet; removed after 3 weeks with cystoscope

Monitoring & Safety Requirements

  • Verify pregnancy status prior to treatment initiation
  • Evaluate bladder mucosal integrity prior to intravesical instillation
  • Monitor for progression of bladder cancer
  • Monitor for signs/symptoms of urinary tract infection (UTI)
  • Patients who could become pregnant must use effective contraception during treatment and for 6 months after final gemcitabine removal from the bladder
  • Patients with partners who could become pregnant must use effective contraception during treatment and for 3 months after final gemcitabine removal

Contraindications & Precautions

  • Hypersensitivity (including anaphylaxis) to gemcitabine or any component of the formulation
  • Perforation of the bladder

Place in Therapy

  • Considered an option for patients desiring bladder-sparing therapy or who are unable to undergo radical cystectomy
  • VA clinical pathways recommend shared decision making among alternative options including pembrolizumab, gemcitabine/docetaxel, nadofaragene firadenovec, or nogapadekin alfa + BCG
