Combination Product: AU-011 in Combination with Medical Laser Administration

Focal injection of AU-011 and laser application with mandatory TURBT (4f)

EXPERIMENTAL

Participants with high-risk NMIBC will receive multiple treatment cycles of focal AU-011 (400 µg per lesion) followed by laser activation prior to mandatory TURBT. Participants will be evaluated for safety and response to AU-011 for up to 12 months from initiation of treatment.

Combination Product: AU-011 in Combination with Medical Laser Administration

Focal injection of AU-011 and laser application with optional TURBT (4g)

EXPERIMENTAL

Participants with intermediate-risk NMIBC will receive multiple treatment cycles of focal AU-011 (400 µg per lesion) followed by laser activation with the option of TURBT. Participants will be evaluated for safety and response to AU-011 for up to 12 months from initiation of treatment. Enrollment will occur in parallel with Cohort 4e, with randomized (1:1) assignment.

Combination Product: AU-011 in Combination with Medical Laser Administration

Focal injection of AU-011 and laser application with option for TURBT (4h)

EXPERIMENTAL

Participants with intermediate-risk NMIBC will receive multiple treatment cycles of focal AU-011 (800 ug per lesion) with laser treatment and option for TURBT. Participants will be evaluated for safety and response to AU-011 up to 12 months from initiation of treatment. This arm is optional and will be run at the discretion of the sponsor.

Combination Product: AU-011 in Combination with Medical Laser Administration

Focal injection of AU-011 and laser application with mandatory TURBT (4i)

EXPERIMENTAL

Participants with high-risk NMIBC will receive multiple treatment cycles of focal AU-011 (800 µg per lesion) before mandatory TURBT. Participants will be evaluated for safety and response to AU-011 up to 12 months from initiation of treatment. This arm is optional and will be run at the discretion of the sponsor.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Meet the following histopathologic requirements for urothelial carcinoma:
  • For Cohorts 1b, 4a-c:
  • histopathological diagnosis of NMIBC (any grade) is required. For participants with first diagnosis of NMIBC, confirmation of urothelial carcinoma by recent biopsy (≤6 months of Screening Visit) is required. Participants with recurrent NMIBC must have a current lesion that clinically appears to be NMIBC with histopathologic confirmation based on TURBT or biopsy within the last 24 months).
  • For Cohorts 4d, 4e, 4g and 4h, a diagnosis of LG IR NMIBC (according to
  • AUA risk classification guidelines) is required, specifically:
  • Multifocal LG Ta; OR
  • Solitary LG Ta \>3 cm; OR
  • Low-grade Ta with prior recurrence(s) within 1 year.
  • For Cohorts 4f and 4i, a diagnosis of HR NMIBC (according to AUA risk classification guidelines) is required, specifically:
  • Ta HG papillary disease with or without CIS; OR
  • T1 papillary disease with or without CIS
  • Participants may be BCG-naïve or may have received prior treatment with BCG for HR or IR NMIBC (BCG-exposed, BCG-failed, BCG-intolerant)
  • BCG-refractory participants are excluded. BCG-refractory is defined by the following:
  • Persistent HG disease at 6 months following adequate BCG (defined as ≥5/6 induction instillations and ≥2 additional doses, either from re-induction or maintenance), OR
  • HG T1 disease at first evaluation (3 months) after BCG, OR
  • +4 more criteria

You may not qualify if:

  • Any additional malignancy that requires active treatment, unless deemed appropriate after discussion by the Investigator with the trial's Medical Monitor.
  • Used an investigational drug or medical device within 30 days or 5 half-lives (whichever is longer) of Visit 1 or be concurrently enrolled in another investigational trial.
  • Active bacterial, fungal, or viral infections - all prior infections must have resolved following optimal therapy and subject must be off all systemic anti-infective agents.
  • Active autoimmune disease, chronic inflammatory condition, or other conditions (like solid organ transplant or bone marrow allograft) requiring concurrent use of any systemic immunosuppressants or steroids.
  • Chronic active hepatitis B or C and HIV.
