Brief Summary
This is a Phase 3, open-label, randomized trial designed to evaluate the DFS of TURBT followed by NDV-1 (sustained-release gemcitabine-docetaxel) versus TURBT followed by surveillance for the treatment of participants with IR-NMIBC.

Outcome Measures
Primary Outcomes (1)
To compare DFS between study arms
Time from randomization to either time of the first recurrence or progression, or death due to any cause, whichever occurs first. It is hypothesized that sustained local delivery of GEM and DOCE (via NDV-01) in participants with IR-NMIBC will result in longer DFS than achieved with observation after TURBT. Under the exponential distribution assumption for DFS, this translates into testing the statistical hypothesis that the hazard ratio is significantly less than 1.0. Primary endpoint will be tested using a one-sided 2.5% level of significance. This study will randomize 302 participants in a 1:1 randomization ratio. The primary efficacy analysis for DFS will be performed when approximately 133 DFS events have been observed. Assuming a 25% recurrence rate (hazard rate 0.14384) in the 2-year DFS in the treated arm, vs. a 40% recurrence rate (hazard rate 0.2554) in the control arm (i.e., a hazard ratio of 0.563 under the exponential distribution assumption for DFS, 53 vs. 80 events.
From date of randomization to at least 2 years of follow-up assessing for DFS events.

Eligibility Criteria
You may qualify if:
- Have a histologically confirmed diagnosis (within 90 days of randomization) of IR NMIBC based on the AUA/SUO criteria of IR NMIBC.
- Participants must have ≥ 1 IBCG risk factors: multiple tumors, early recurrence (Within 1 year), frequent recurrences (\> 1 per year), tumor size (\> 3 cm), failure of prior intravesical therapy.
- Visible papillary disease must be fully resected prior to randomization, and absence of disease must be documented at Screening cystoscopy. The same method for visualizing disease at Screening cystoscopy should be used throughout for the participant (white light versus enhanced assessment method).
- Patients with LG T1 may be eligible after repeat-TURBT (within 4 weeks of first TURBT) if the repeat pathology shows non-invasive (Ta or less) or no disease. Original and repeat-TURBT must confirm that muscularis propria is present and uninvolved in the specimen. TURBT to occur within 4 months of screening. All pathology specimens must be predominantly urothelial (transitional cell) and have less than 20% variant (e.g., sarcomatoid, squamous component) histology.
You may not qualify if:
- Histologically confirmed diagnosis of HR NMIBC (including CIS) or MIBC, locally advanced, nonresectable, or metastatic urothelial carcinoma at any time prior to enrollment.
- Has had urothelial carcinoma outside of the urinary bladder, (including prostatic urethra, ureter, or renal pelvis) or has a predominant histological variant of UC. Ta/any T1, CIS of the upper urinary tract is allowable if treated with complete nephroureterectomy more than 24 months prior to initiating study.
- Participant has tumor(s) involving the prostatic urethra (ductal or stromal).
- N+ and/or M+ per CT/MR urography.
