"These compelling findings shed light on the potential of UGN-102 as a nonsurgical primary treatment for low-grade intermediate-risk bladder cancer," said William Huang, M.D., Urologic Oncologist, Professor and Vice Chair of Urology, NYU Grossman School of Medicine. "These data are an encouraging step forward in addressing the broad spectrum of LG-IR-NMIBC and potentially curbing the high rates of disease recurrence associated with it."

In the Phase 3 ATLAS study, 282 patients with new or recurrent LG-IR-NMIBC were randomized to primary treatment with UGN-102 ± TURBT or TURBT alone. In the overall study population, Disease Free Survival (DFS) and DOR favored primary treatment with UGN-102 ± TURBT compared to TURBT alone. Complete response (CR) rates at the 3-month disease assessment were similar in both arms. While DFS and DOR rates were previously shared for both arms of the study, these are the first data specifically looking at the rates among new and recurrent patients within the UGN-102 ± TURBT arm. In this analysis using Kaplan Meier methods, DOR at 12 months after achieving CR at 3 months was 87.5% and 69.1% in new and recurrent patients, respectively. Also, patients achieved similar probabilities of DFS rates for UGN-102 at 15 months from randomization (77.4% and 63.2% in new and recurrent patients, respectively).

"These insightful data underscore the potential of UGN-102 impacting the treatment landscape for LG-IR-NMIBC," said Mark Schoenberg, M.D., Chief Medical Officer, UroGen. "Our aim is for UGN-102 to emerge as a non-surgical option for LG-IR-NMIBC, potentially sparing patients from the complexities and burdens associated with repetitive surgeries, including their inherent risks, side effects, and substantial impact on both individuals and healthcare systems."

Topline data from both the ATLAS trial and the Phase 3 ENVISION trial were initially shared in July of 2023. Twelve-month DOR data from the pivotal Phase 3 ENVISION trial are expected in June 2024.

About UGN-102

UGN-102 (mitomycin) for intravesical solution is an innovative drug formulation of mitomycin, currently in Phase 3 development for the treatment of LG-IR-NMIBC. Utilizing UroGen’s proprietary RTGel technology, a sustained release, hydrogel-based formulation, UGN-102 is designed to enable longer exposure of bladder tissue to mitomycin, thereby enabling the treatment of tumors by non-surgical means. UGN-102 is delivered to patients using a standard urinary catheter in an outpatient setting. Assuming positive findings from the durability of response endpoint from the ENVISION Phase 3 study, UroGen anticipates completing its New Drug Application (NDA) submission for UGN-102 in September 2024 with a potential U.S. Food and Drug Administration (FDA) decision as early as the first quarter of 2025.

About Non-Muscle Invasive Bladder Cancer (NMIBC)

In the U.S. bladder cancer is the second most common urologic cancer in men. LG-IR- NMIBC represents approximately 22,000 newly diagnosed bladder cancer patients each year and an estimated 60,000 recurrences annually among patients diagnosed from previous years. Bladder cancer primarily affects older populations with the median age of diagnosis 73 years and an increased risk of comorbidities. Guideline recommendations for the management of NMIBC include TURBT as the standard of care (SOC). Up to 70 percent of NMIBC patients experience at least one recurrence and LG-IR-NMIBC patients are even more likely to recur and face repeated TURBT procedures.

About ATLAS

ATLAS was a global, open-label, randomized controlled Phase 3 trial designed to assess the efficacy and safety of UGN-102, with or without TURBT, vs. TURBT alone in patients diagnosed with LG-IR-NMIBC. The trial enrolled 282 patients in clinical sites in the U.S., Europe and Israel. Patients were randomized 1:1 to either UGN-102 or TURBT. Patients in the UGN-102 arm were treated with six weekly intravesical instillations of UGN-102. At the 3-month time point, patients were assessed for response. Patients who demonstrated a complete response to either UGN-102 or TURBT, were assessed for long-term duration of response. Patients who demonstrated presence of persistent disease at 3-months, in either arm, underwent a TURBT and continued for long-term follow-up for evidence of recurrence. The primary endpoint of the study is disease-free survival. Learn more about the ATLAS trial at www.clinicaltrials.gov (NCT04688931).

About ENVISION

The Phase 3 ENVISION trial is a single-arm, multinational, multicenter study evaluating the efficacy and safety of UGN-102 (mitomycin) for intravesical solution as primary chemoablative therapy in patients with LG-IR-NMIBC. The Phase 3 ENVISION trial completed target enrollment with approximately 240 patients across 56 sites. Study participants received six once-weekly intravesical instillations of UGN-102. The primary endpoint evaluated the CR rate at the 3-month assessment after the first instillation, and the key secondary endpoint will evaluate durability over time in patients who achieved a CR at the 3-month assessment. Based on discussions with the FDA, and assuming positive findings, UroGen anticipates submitting an NDA for UGN-102 in September 2024. Learn more about the Phase 3 ENVISION trial at www.clinicaltrials.gov (NCT05243550).

On May 4, 2024 UroGen Pharma Ltd. (Nasdaq: URGN), a biotech company dedicated to developing and commercializing novel solutions that treat urothelial and specialty cancers, reported the results of a sub-analysis from a real-world patient cohort review of JELMYTO (mitomycin) for pyelocalyceal solution presented at the American Urological Association Meeting 2024 in San Antonio, TX (Press release, UroGen Pharma, MAY 4, 2024, View Source [SID1234642644]). The study includes a stepwise approach to retrograde administration of JELMYTO and reports that retrograde administration of JELMYTO in the clinic (n=20) produced a 60% complete response rate in patients and ureteral stents were placed in 25% of patients, which is lower than the rate reported in the pivotal OLYMPUS study.

"The retrograde instillation of JELMYTO for the clinical management of low-grade upper tract urothelial cancer is FDA-approved and offers a safe and efficacious mode of administration, and this study in a real-world population adds to the growing body of evidence supporting retrograde administration in appropriate patients," said Khurshid Ridwan Ghani, MBChB, MS, FRCS, Professor of Urology, Director, Michigan Urological Surgery Improvement Collaborative. "The stepwise approach outlined in this study offers valuable insights into achieving positive efficacy and safety outcomes, in the clinic with the procedure done under local anesthesia, with notable durability of response observed."

In the OLYMPUS study all enrolled patients (n=71) received retrograde administration of JELMYTO. In the OLYMPUS study 58% (n=41) of patients achieved a complete response, defined as the absence of tumor lesions 3 months after initiation of JELMYTO treatment assessed by urine cytology and ureteroscopy. Ureteric obstruction* was reported in 58% (n=41) of patients treated with JELMYTO and 88% (n=36) of that subgroup went on to receive ureteral stent placement. For additional information about the retrograde administration of JELMYTO, consult the JELMYTO Instructions for Administration accompanying the Full Prescribing Information.

In this retrospective real-world study, 20 patients with a mean tumor burden of 1.67 cm received at least one dose of JELMYTO via the retrograde mode of administration, of which 16 (80%) completed six instillations. Twelve patients (60%) had a complete response and seven patients (35%) received at least one dose of monthly maintenance therapy, of which five demonstrated durability of response (4 patients remained tumor-free at 14.25-month follow-up and 1 patient at 24 months). Six patients (30%) had an adverse event related to the urinary system. Ureteral stents were placed in five patients for stenosis (25%); of which four were transient, with no subsequent obstruction. Only one patient (5%) required permanent stenting. Three patients who were unable to tolerate the retrograde approach had antegrade administration of JELMYTO via a nephrostomy tube.

"These findings emphasize the versatility of JELMYTO administration and also underscore the significance of continuous research and innovation in elevating treatment standards for urothelial cancers," remarked Mark Schoenberg, M.D., Chief Medical Officer at UroGen.

The limitations of this sub-analysis include the small sample size, the retrospective design, lack of a control group, and the lack of a centralized pathology review and standardized clinicopathologic assessment.

To further explore the full potential of JELMYTO for the treatment of patients with upper tract urothelial cancers (UTUC), investigators are in the process of enrolling the prospective and retrospective uTRACT Registry to capture data in a large-scale, standardized manner to report further on patient outcomes following JELMYTO treatment including longitudinal follow-up.

*Includes hydronephrosis, obstructive uropathy, pelvic-ureteric obstruction, ureteric obstruction, ureteric stenosis, and urinary tract obstruction.

About JELMYTO

JELMYTO (mitomycin) for pyelocalyceal solution is a mitomycin-containing reverse thermal gel containing 4 mg mitomycin per mL gel indicated for the treatment of adult patients with low grade-UTUC (LG-UTUC). JELMYTO is a viscous liquid when cooled and becomes a semi-solid gel at body temperature. The drug slowly dissolves over four to six hours after instillation and is removed from the urinary tract by normal urine flow and voiding. It is approved for administration in a retrograde manner via ureteral catheter or antegrade through nephrostomy tube. The delivery system allows the initial liquid to coat and conform to the upper urinary tract anatomy. The eventual semisolid gel allows for chemoablative therapy to remain in the collecting system for four to six hours without immediately being diluted or washed away by urine flow.

About Upper Tract Urothelial Cancer (UTUC)

Urothelial cancer is the ninth most common cancer globally and the eighth most lethal neoplasm in men in the U.S. Between five percent and ten percent of primary urothelial cancers originate in the ureter or renal pelvis and are collectively referred to as UTUC. In the U.S., there are approximately 6,000 – 7,000 new or recurrent LG-UTUC patients annually. Most cases are diagnosed in patients over 70 years old, and these older patients often face comorbidities. There are limited treatment options for UTUC, with the most common being endoscopic surgery or nephroureterectomy (removal of the entire kidney and ureter). These treatments can lead to a high rate of recurrence and relapse.

About PARG
Poly(ADP-ribose) glycohydrolase (PARG) is a key protein that plays a pivotal role in repairing damaged DNA. PARG breaks down poly(ADP-ribose) (PAR) chains, which serve to attract DNA repair factors to sites of DNA damage. Cancers are by default genomically instable and cannot tolerate excessive DNA damage as opposed to normal cells. By inhibiting PARG, the degradation of PAR chains is halted, leading to a block of DNA repair and the accumulation of persistent and lethal DNA damage. Cancers with intrinsic deficiencies in particular DNA repair pathways exhibit exceptional sensitivity to pharmacological PARG inhibition, which presents a prime opportunity for therapeutic intervention.

On May 3, 2024 Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and genetic testing, reported a new publication in JCO Precision Oncology reporting on the ability of its personalized and tumor-informed molecular residual disease (MRD) test, Signatera, to detect recurrence early in patients with early-stage breast cancer (Press release, Natera, MAY 3, 2024, View Source [SID1234642642]).

The study evaluated a total of 1,136 prospectively collected and banked plasma samples from 156 early-stage breast cancer patients enrolled in the multi-site Exploratory Breast Lead Interval Study (EBLIS). Patients were followed for up to 12 years after surgery and adjuvant chemotherapy, with blood samples collected semi-annually and then analyzed using Signatera. Key findings include:

Signatera detected relapse up to 38 months earlier than imaging (median lead time 10.5 months), with an overall sensitivity of 88.2% (30/34)
Relapse-free survival (RFS) and overall survival (OS) were significantly worse in patients who were ctDNA-positive, regardless of hormone receptor and HER2 subtype (HR 52.98 and 53.69, respectively). In a multivariate analysis, ctDNA status was the most significant factor associated with RFS and OS.
"The EBLIS study shows that post-operative monitoring with Signatera can detect recurrence much earlier than scans, opening up a critical window for early therapeutic intervention and clinical trials focused on molecular recurrence," said Charles Coombes, MD, PhD professor of medical oncology at the Imperial College London and principal investigator of the EBLIS study. "Additionally, we demonstrate the value of longitudinal testing in providing reassurance to breast cancer patients, as those who test serially ctDNA-negative show better clinical outcomes."

Breast cancer is the most common cancer in women in the U.S. and the second leading cause of cancer death in women.1 The current standard of care for most patients with early-stage breast cancer consists of surgery and adjuvant chemotherapy and/or endocrine therapy.2,3 However, patients with early-stage breast cancer experience a rate of local recurrence of roughly 15% and distant metastases of 21% after primary treatment.4

"This expanded EBLIS study reinforces the importance of early recurrence detection with Signatera and the potential to improve care management for patients with breast cancer," said Minetta Liu, MD, chief medical officer of oncology. "The findings also bolster the evidence for long-term monitoring of high-risk breast cancer patients, who often face late recurrences."

About Signatera

Signatera is a personalized, tumor-informed, molecular residual disease test for patients previously diagnosed with cancer. Custom-built for each individual, Signatera uses circulating tumor DNA to detect and quantify cancer left in the body, identify recurrence earlier than standard of care tools, and help optimize treatment decisions. The test is available for clinical and research use and is covered by Medicare for patients with colorectal cancer, breast cancer, ovarian cancer and muscle invasive bladder cancer, as well as for immunotherapy monitoring of any solid tumor. Signatera has been clinically validated across multiple cancer types and indications, with published evidence in more than 60 peer-reviewed papers.
