Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 85 years
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Participants must meet ALL of the following criteria for inclusion in the study:
- Male or female participants 18 years of age or older.
- Histologic confirmation of BCG naïve non-muscle invasive urothelial carcinoma of the bladder (mixed histology tumors allowed if urothelial histology is predominant histology) AND either i) histologically confirmed presence of NMIBC CIS (with or without Ta/T1 papillary disease) OR ii) primary or recurrent stage Ta and/or T1 papillary tumors following transurethral resection (TUR).
- Absence of resectable disease after TURBT procedures (residual CIS acceptable; participants with T1 tumors must undergo repeat resection and biopsy [inclusive of muscularis propria] of the T1 tumor site if initial biopsy did not include muscularis propria).
- Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.
- Voluntary written informed consent and agreement to comply with all protocol specified procedures and follow-up evaluations.
Who cannot join
- Participants with ANY of the following criteria are excluded from participation in the study:

- Liver function abnormalities as indicated by ongoing hepatic enzyme elevation (aspartate aminotransferase [AST] or alanine aminotransferase [ALT]) > 2 X upper limit of normal (ULN)
Show all 18Show fewer
- Renal insufficiency as indicated by a creatinine level >3 X ULN
- History of or evidence of muscle-invasive, locally advanced, metastatic and/or extravesical bladder cancer (inclusive of the 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 or hormone control.
- Symptomatic congestive heart failure (CHF), New York Heart Association (NYHA) Class III or IV heart failure or other clinical signs of severe cardiac dysfunction.
- Severe/unstable angina pectoris, or myocardial infarction within 6 months prior to study entry.

- Concurrent febrile illness, active urinary tract infection, active tuberculosis, a history of hypotension or anaphylactic reactions.
- Ongoing chronic systemic steroid therapy required (>10 mg oral prednisone daily or equivalent).
- Women who are pregnant or 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 and for 90 days post last dose of study drug.

- Concurrent use of other investigational agents (not including FDA authorized drugs for the prevention and treatment of COVID-19).
- Other illness or condition, 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.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Intravesical Recombinant Mycobacterium (rMBCG) in people with NMIBC, run by ImmunityBio, Inc. at 9 sites in United States.
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 6 inclusion and 18 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: looking for participants now, as of the sponsor's last update on 27 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jayson Garmizo (310-912-2230, jayson.garmizo@immunitybio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary endpoint is to assess safety as measured by the incidence and severity of adverse events. (time frame: Approximately 7 months). 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 27 Mar 2026.
