UroGen Reports Positive Data from Two Important Studies: UGN-101 OLYMPUS Pivotal Trial in LG UTUC and UGN-102 Phase 2b OPTIMA II Trial in LG Bladder Cancer
Consistent Complete Response (CR) Rate of 59 Percent in Patients with Low-Grade Upper Tract Urothelial Cancer (LG UTUC)
Durability of Response Determined to be 89 Percent at Six Months and 84 Percent at 12 Months
Rolling NDA Submission on Track for Q4 2019 with Planned Launch in 1H 2020
Data Demonstrates CR Rate of 63 Percent in Patients with Intermediate Risk Low-Grade Non-Muscle Invasive Bladder Cancer (LG NMIBC)
Company Completes Enrollment Ahead of Schedule in OPTIMA II Phase 2b Trial
Results from a final analysis of the primary endpoint for pivotal Phase 3 OLYMPUS showed that investigational UGN-101 (mitomycin gel) for instillation demonstrated a 59 percent CR rate in patients with LG UTUC. Findings were consistent with previously presented results.
The final analysis of the primary endpoint showed that in the OLYMPUS intent-to-treat population, 42 of the 71 patients (59 percent) achieved a CR. Forty-one patients entered follow-up, which is still ongoing. Durability of response was determined by Kaplan-Meier to be 89 percent at 6 months and 84 percent at 12 months after primary disease evaluation (PDE). The estimated median time-to-recurrence was 13.0 months. Thirty four of the 71 patients treated in the study were initially characterized by the treating physician as having endoscopically unresectable tumor at baseline. Twenty of 34 patients (59 percent) achieved a CR at the PDE assessment and 12-month durability was identical for this subgroup.
In OLYMPUS, the most common treatment emergent adverse events (TEAE) included ureteral stenosis, urinary tract infection, hematuria, flank pain, dysuria, renal impairment, hydronephrosis and frequency. Most TEAEs were characterized as mild to moderate and transient. Sixty-seven percent (48/71) of patients in the trial experienced an adverse event involving the renal/urinary tract. Of these, 23 percent (11/48) did not require surgical intervention, 50 percent (24/48) required temporary ureteral stent placement, 23 percent (11/48) required a long-term ureteral stent and 4 percent (2/48) required nephroureterectomy. At the time of database lock, the most common Grade 3 TEAE’s included ureteral stenosis (8.5 percent), hematuria, flank pain, and urinary tract infection (3 percent each). There was one Grade 4 TEAE of subdural hematoma (1.4 percent).
“We are pleased that the six-month durability from this analysis remains consistent with previously presented results and are very pleased with the durability observed at 12 months in evaluated patients. These findings provide further support for the concept of chemoablation with UGN-101 as an initial kidney-sparing treatment option for patients with LG UTUC,” said
The Company also presented interim results from the Phase 2b OPTIMA II trial of investigational UGN-102 (mitomycin gel) for intravesical instillation for patients with intermediate risk LG NMIBC, defined as those with one or two of the following criteria: multifocal disease, large tumors and rapid rates of recurrence. The single-arm, open label study trial recently completed enrollment of 62 patients at clinical sites across the U.S. and
CR at PDE
“Achieving our enrollment goal ahead of schedule is a testament to the enthusiasm and need for this type of innovative approach to treatment in LG NMIBC. ‘Intermediate risk’ patients experience what can be viewed as a form of surgical failure, and many undergo multiple surgical procedures, known as transurethral resection of bladder tumor (TURBT), to manage these recurrences. We are encouraged by the data observed in this tough-to-treat population for whom the standard of care is really not effective,” said
In the interim data from OPTIMA II, the most common adverse events observed were dysuria, pollakiuria, fatigue, hematuria and urinary tract infection. The majority of these treatment-emergent adverse events were characterized as mild or moderate and transient.
The Company intends to initiate a pivotal Phase 3 trial in 2020 following discussion with the
About The Phase 3 OLYMPUS Trial
OLYMPUS (Optimized DeLivery of Mitomycin for Primary UTUC Study) is a pivotal, open-label, single-arm Phase 3 clinical trial of UGN-101 (mitomycin gel) for instillation to evaluate the safety, tolerability and tumor ablative effect of UGN-101 in patients with low-grade UTUC. The trial enrolled 71 patients at clinical sites across
UGN-101 (mitomycin gel) for instillation is an investigational drug formulation of mitomycin in Phase 3 development for the treatment of low-grade upper tract urothelial cancer (LG UTUC). Utilizing the RTGel™ technology platform, UroGen’s proprietary sustained release, hydrogel-based formulation, UGN-101 is designed to enable longer exposure of urinary tract tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. UGN-101 is delivered to patients using standard ureteral catheters. The Company initiated its rolling submission of the UGN-101 New Drug Application (NDA) to the
About The Phase 2b OPTIMA II Trial
OPTIMA II (OPTimized Instillation of Mitomycin for BlAdder Cancer Treatment) is an open-label, single-arm, multi-center Phase 2b clinical trial of UGN-102 (mitomycin gel) for intravesical instillation to evaluate the safety and efficacy of UGN-102 in patients with intermediate risk low-grade non-muscle invasive bladder cancer (LG NMIBC) at intermediate risk of recurrence. Intermediate risk of progression is defined as one or two of the following: multiple tumors, solitary tumor >3 cm, or recurrence (≥ 1 occurrence of LG NMIBC within 1 year of the current diagnosis). The trial enrolled 62 patients at clinical sites across
