Details and patient eligibility

About

This is a Phase 3, open-label single-arm trial designed to evaluate the safety and efficacy of NDV-01 (sustained-release gemcitabine-docetaxel) in adult participants with NMIBC with CIS who have failed BCG therapy and who have failed first-line therapy for BCG-unresponsive NMIBC (approved or in development) and are recommended for radical cystectomy.

Full description

Participants will receive an induction course and then monthly maintenance courses of NDV-1 (sustained-release gemcitabine-docetaxel) through 3 years, if there is no disease recurrence.

Participants will received an induction course of NDV-01 (6-bi-weekly intravesical instillations). Those who achieve a complete response (CR) at 3 months will be eligible for monthly maintenance instillations through year 3.

Disease status will be assessed using urine cytology, cystoscopy, and directed TURBT/biopsy (if indicated) every 3 months for the first 2 years after randomization or until disease recurrence.

Inclusion criteria

BCG-unresponsive NMIBC with CIS of the bladder, with or without coexisting papillary Ta/T1 tumor(s) who are ineligible for or have elected not to undergo cystectomy at the time of enrollment and have experienced 1) CIS disease within 12 months of treatment.
Participants with BCG-unresponsive disease must have received up to two first-line therapies or BCG-unresponsive disease and who are recommended for radical cystectomy. Such therapies may include agents approved or in development (e.g., pembrolizumab, nadofaragene firodenovec, nogapendekin alfa inbakicept-pmln, cretostimogene grenadenorepvec, detalimogene voraplasmid, TARA-002, gemcitabine intravesical system (INLEXZO®), gemcitabine, MMC, or valrubicin monotherapy. Participants will have demonstrated recurrence or intolerance after one or two first-line therapy(ies).
All specimens must be predominantly urothelial (transitional cell) carcinoma with or without squamous or glandular differentiation. Pure squamous or glandular tumors will not be included. Participants with less than 10% micropapillary histology will be included. All other variant histology (e.g. plasmacytoid, small cell, nested, trophoblastic variants) will not be included.

Exclusion criteria

- Has had urothelial carcinoma outside of the urinary bladder (i.e., 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 computerized tomography (CT)/Magnetic Resonance Imagery (MR) urography. History of prior T2/T3 urothelial carcinoma of the bladder.
