About this study
Official title: A Study of Intravesical Bacillus Calmette-Guerin (BCG) in Combination With ALT-803 (N-803) in Patients With Non-Muscle Invasive Bladder Cancer
This is a Phase Ib/IIb, randomized, two-cohort, open-label, multicenter study of intravesical N-803 plus BCG versus BCG alone, in BCG naïve patients with high-grade NMIBC.
Read the detailed description
The study includes a dose escalation phase (phase Ib) and an expansion phase (phase IIb).
In the phase Ib, patients will be treated with intravesical N-803 in combination with BCG. The purpose of the phase Ib portion of the study is to evaluate the safety, identify the Maximum Tolerated Dose (MTD) of N-803 and determine the Recommended Dose (RD) level of N-803 in combination with BCG for the phase IIb expansion.
In the phase IIb expansion, patients will be randomized to receive either intravesical N-803 in combination with BCG or BCG alone. Patients will be enrolled into one of two study cohorts (Cohort A and Cohort B). These will be two independent study cohorts, evaluated separately for treatment efficacy.
- Conditions
- Non-muscle Invasive Bladder Cancer
- Being tested
- BCG (50mg/instillation) + N-803 (400 μg/instillation), BCG (50mg/instillation)
- Keywords
- antitumor, BCG, bladder cancer, cancer, immunotherapy, instillation, interleukin-15, intravesical, naive, non-muscle invasive, transitional cell carcinoma, ALT-803, N-803
- Medical subject headings

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?
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?
Complete Response (CR) Rate (time frame: 6 Months). 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?
On the ClinicalTrials.gov record for NCT02138734, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
