Show all 11Show fewer
  • Have not received prior intravesical BCG; or
  • Previously received BCG but stopped receiving more than 3 years before date of randomization.
  • BCG-exposed disease, defined as patients who have received at least 1 dose of BCG and do not meet the BCG-unresponsive criteria.
  • Agreement to practice effective contraception for female participants of child-bearing potential and non-sterile males. Female participants of child-bearing potential must agree to use effective contraception for up to 1 year after completion of therapy, and non-sterile male participants must agree to use a condom for up to 4 months after treatment. Effective contraception includes surgical sterilization (eg, vasectomy, tubal ligation), 2 forms of barrier methods (eg, condom, diaphragm) used with spermicide, and intrauterine devices (IUDs).
  • Voluntary written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization and agree to comply with all protocol-specified procedures and follow-up evaluations.

Who cannot join

  • Life expectancy < 2 years.
  • BCG-unresponsive disease, defined as:
  • Persistent or recurrent CIS (± recurrent Ta/T1 disease) within 12 months of receiving adequate BCG (at least 5 of 6 doses of an initial induction course plus either at least 2 of 3 doses of maintenance therapy or at least 2 of 6 doses of a second induction course); or
  • Recurrent high-grade Ta/T1 disease within 6 months of completion of adequate BCG (at least 5 of 6 doses of an initial induction course plus either at least 2 of 3 doses of maintenance therapy or at least 2 of 6 doses of a second induction course); or
  • T1 high-grade disease at the first evaluation following an induction BCG course alone (at least 5 of 6 doses of an initial induction course)
  • Urinary tract infection or urinary retention.
Show all 17Show fewer
  • Must not have had urothelial carcinoma or histological variant at any site outside of the urinary bladder (that is, urethra, ureter, or renal pelvis/calyces). Ta/any T1/CIS of the upper urinary tract (including renal pelvis and ureter) is allowable if treated with complete nephroureterectomy more than 24 months prior to randomization.
  • Presence of any bladder or urethral anatomic feature (example, urethral stricture) that, in the opinion of the Investigator, may prevent the safe administration of intravesical N-803 or BCG. Participants with tumors involving the prostatic urethra in men will be excluded.
  • History of clinically significant polyuria with recorded 24-hour urine volumes greater than 4000 milliliters (mL).
  • Indwelling catheters are not permitted; however, intermittent catheterization is acceptable.
  • History of or evidence of muscle-invasive, locally advanced, metastatic and/or extravesical bladder cancer (inclusive of prostatic urethra); or any other cancer within the past 5 years that is progressing or requires active treatment. Exceptions are adequately treated basal cell or squamous cell skin cancer that has undergone potentially curative therapy or in situ cervical cancer; and adequately treated stage I or II cancer or stable prostate cancer from which the participant is currently in complete remission and is under active surveillance.
  • Receiving investigational or commercial anticancer agents or anticancer therapies other than supportive care therapies for active disease within 28 days of enrollment.
  • Concurrent use of other investigational agents.
  • Concurrent febrile illness, active tuberculosis, a history of hypotension of anaphylactic reactions.
  • Ongoing chronic systemic steroid therapy required (> 10 mg prednisone daily or equivalent).
  • Women who are pregnant and nursing. Female participants of childbearing potential must have a negative pregnancy test and must adhere to using a medically acceptable method of birth control prior to screening and agree to continue its use during the study and for 30 days after the last dose of study drug, or be surgically sterilized (eg, hysterectomy or tubal ligation). Women of childbearing potential are defined as any female who has experienced menarche and who is NOT permanently sterile or postmenopausal. Postmenopausal is defined as 12 consecutive months with no menses without an alternative medical cause. Males must agree to use barrier methods of birth control while on study for 90 days post last dose of study drug.
  • Other illnesses or conditions, including laboratory abnormalities, which in the opinion of the Investigator would exclude the participant from participating in this study. This includes, but is not limited to, serious medical conditions or psychiatric illness likely to interfere with participation in the study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BCG (50 mg) plus ANKTIVA (400 µg)Biological

    First (Priming) Treatment Period:

    50 mg BCG plus 400 µg ANKTIVA intravesically, weekly for 3 consecutive weeks

    Second (Induction) Treatment Period:

    50 mg BCG plus 400 µg ANKTIVA intravesically, weekly for 6 consecutive weeks

    Third (Re-Induction or Maintenance) Treatment Period:

    50 mg BCG plus 400 µg ANKTIVA intravesically, weekly for 6 consecutive weeks

  • BCG (50 mg)Biological

    First (Priming) Treatment Period:

    50 mg BCG intravesically, weekly for 6 consecutive weeks

    Second (Induction) Treatment Period:

    Participants may be eligible for additional treatment during the second treatment period depending upon the results of the second response assessment (week 21).

    Third (Re-Induction or Maintenance) Treatment Period:

    Participants may be eligible for additional maintenance treatment during the third treatment period depending upon the results of the week 33 and subsequent response assessments, which occur every 3 months through month 6 and every 6 months thereafter through month 36.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical Complete Response (CR) Rate

    First response assessment, as determined by Investigator assessment of cystoscopy, cytology, and biopsy as clinically indicated

    Measured: Study Week 7

  2. Disease Free Survival

    DFS, defined as the time from randomization until recurrence of HG Ta (excluding LG Ta) disease or any grade T1 disease, new CIS, disease progression, cystectomy, change in therapy indicative of more advanced disease, or death due to any cause, whichever occurs first, regardless of re-induction.

    Measured: Approximately 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing BCG (50 mg) plus ANKTIVA (400 µg) and BCG (50 mg) in people with NMIBC, run by ImmunityBio, Inc..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical Complete Response (CR) Rate (time frame: Study Week 7). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2026.
