En bloc resection of bladder tumor: Is it the way forward?

The FDA has accepted a new drug application (NDA) for zoliflodacin, an investigational first-in-class, single-dose, spiropyrimidinetrione oral antibiotic for the treatment of adult and pediatric patients 12 years and older with uncomplicated gonorrhea, Innoviva Specialty Therapeutics announced in a news release.

The Prescription Drug User Fee Act (PDUFA) target action date for the application is December 15, 2025.

Zoliflodacin is an oral antibiotic that inhibits type II topoisomerase, a bacterial enzyme that plays a key role in bacterial function and reproduction. According to the company, “If approved, zoliflodacin would be the first new antibiotic for treating gonorrhea in decades.”

The FDA has also granted a Qualified Infectious Disease Product designation to zoliflodacin, which enables the agent to benefit from priority review and market exclusivity.

“Today’s acceptance of the zoliflodacin NDA marks significant progress toward delivering health care providers with a potential new oral treatment option for uncomplicated gonorrhea, including infections caused by drug-resistant strains,” said David Altarac, MD, Chief Medical Officer of Innoviva Specialty Therapeutics, in the news release.

 “We look forward to working closely with the FDA during its review and, if approved, we are committed to expediting the availability of zoliflodacin to patients in the U.S.”

The NDA for zoliflodacin is supported by data from several clinical trials conducted through a collaboration with the Global Antibiotic Research & Development Partnership (GARDP). This portfolio of studies includes a pivotal phase 3 trial (NCT03959527) that evaluated zoliflodacin vs a standard of care (SOC) regimen (500 mg ceftriaxone intramuscular plus 1g oral azithromycin) in patients with uncomplicated gonorrhea.

Overall, the trial met its primary end point by demonstrating that zoliflodacin was non-inferior to the SOC regimen regarding microbiological response at the urogenital site at the test of cure visit (6 +/- 2 days following treatment). Specifically, the microbiological cure rate was 90.9% in the zoliflodacin arm vs 96.2% in the ceftriaxone/azithromycin arm, representing a difference of 5.3% (95% CI, 1.4% to 8.7%) across patients in the micro-intent-to-treat (ITT) population.

The 2 cohorts also demonstrated comparable results on the trial’s secondary end point of microbiological response at extragenital (rectal or pharyngeal) sites. Specifically, at pharyngeal sites, the cure rate was 79.2% in the zoliflodacin arm vs 78.6% in the ceftriaxone/azithromycin arm (difference, -0.67%; 95% CI, -20.8 to 16.3). At rectal sites, the cure rate was 87.3% and 88.6%, respectively (difference, 1.23%; 95% CI, -14.4 to 12.6).

Zoliflodacin was generally well-tolerated in the trial. Treatment-emergent adverse events (TEAEs) occurred in 46.2% of patients in the zoliflodacin arm vs 46.4% of patients in the ceftriaxone/azithromycin arm. The most common TEAEs in the zoliflodacin arm included headache (9.9%), neutropenia (6.8%), and leukopenia (3.9%).

There were no deaths or serious adverse events reported in either arm.

In total, the phase 3 trial included 930 patients with uncomplicated gonorrhea, including patients living with HIV. The study enrolled participants across 16 clinical trial sites in the US, Belgium, the Netherlands, South Africa, and Thailand.

According to Innoviva, the phase 3 study was “the largest clinical trial ever conducted for a new treatment against gonorrhea infection.”

Those enrolled in the study were randomly assigned 2:1 to receive 3 g single-dose, oral zoliflodacin (n = 621) or to 500 mg ceftriaxone intramuscular plus 1g oral azithromycin (n = 309). The primary end point was microbiological cure by culture at urogenital sites in the micro-ITT populations, with a non-inferiority margin of 12%. The trial’s secondary end point was microbiological cure at extragenital sites.

“This important milestone demonstrates the crucial role that public-private partnerships can play in tackling the escalating global antimicrobial resistance crisis,” said Manica Balasegaram, Executive Director of GARDP, in the news release.

 “If zoliflodacin is approved, this collaboration paves the way for millions of people across the world to get access to a potentially powerful new drug to treat multidrug-resistant gonorrhea.”

The FDA has accepted a Biologics License Application (BLA) seeking approval of nivolumab (Opdivo) co-formulated with Halozyme’s proprietary recombinant human hyaluronidase (rHuPH20), or subcutaneous nivolumab, for the treatment of patients with all previously approved solid tumor indications for nivolumab as a monotherapy, monotherapy maintenance following completion of combination therapy with nivolumab plus ipilimumab (Yervoy), or in combination with chemotherapy or cabozantinib (Cabometyx).

Nivolumab is currently approved under several indications, including in combination with ipilimumab for the first-line treatment of patients with intermediate- or poor-risk advanced renal cell carcinoma (RCC), in combination with cabozantinib for the first-line treatment of patients with advanced RCC, for the treatment of patients with advanced RCC who have received prior anti-angiogenic therapy, and in combination with cisplatin and gemcitabine for the first-line treatment of patients with unresectable or metastatic urothelial carcinoma.

The FDA is set to have a decision regarding the subcutaneous nivolumab formulation on or by December 29, 2024.

 According to a news release from Bristol Myers Squibb,

 approval of the formulation would make it the first and only subcutaneously administered PD-1 inhibitor.

“We believe subcutaneous nivolumab has the potential to make a significant difference in the lives of patients, which is reinforced by the FDA’s acceptance of our application,” said Gina Fusaro, PhD, vice president, global program lead, Bristol Myers Squibb, in the news release.

 “Opdivo is a foundational PD-1 inhibitor approved for many different types of cancer, and our continued investment in research that puts patients first remains a priority. If approved by the FDA, the subcutaneous administration of nivolumab would provide patients and their physicians with a new option that delivers the same well-known benefits as IV Opdivo but with the improved convenience of an injection administered in 3 to 5 minutes rather than a 30-to-60-minute infusion.”

The BLA submission is supported by findings from the phase 3 CheckMate-67T trial (NCT04810078), in which subcutaneous nivolumab met the study’s co-primary end points by demonstrating noninferiority to intravenous (IV) nivolumab regarding time average nivolumab serum concentration over 28 days (C

; geometric mean ratio [GMR}, 2.098; 90% CI, 2.001-2.200) and minimum serum concentration at a steady state (C

Data from the study, which were presented at the 2024 American Society of Clinical Oncology Genitourinary Cancers Symposium in San Francisco, California,

 also showed that subcutaneous nivolumab demonstrated noninferiority to IV nivolumab in the key powered secondary end point of objective response rate (ORR). Specifically, the subcutaneous arm demonstrated an ORR of 24.2% (95% CI, 19.0-30.0) per blinded independent central review (BICR), compared with 18.2% (95% CI, 13.6-23.6) in the IV arm.

The safety profile for subcutaneous nivolumab was consistent with that of the IV formulation. Among patients who received the subcutaneous formulation, 8.1% experienced injection-site reactions, with all being low-grade and transient. Deaths due to study drug toxicity occurred in 3 patients in the subcutaneous arm and 1 patient in the IV arm. Most deaths that occurred during the study were due to disease progression.

In total, the phase 3, open-label CheckMate-67T trial enrolled 495 patients with advanced or metastatic ccRCC who had received prior systemic therapy. Patients were randomly assigned 1:1 to receive 1200 mg subcutaneous nivolumab plus rHuPH20 every 4 weeks (n = 248) or to 3 mg/kg IV nivolumab every 2 weeks (n = 247) for up to 2 years of treatment or until disease progression, unacceptable toxicity, withdrawal, or death.

The co-primary pharmacokinetic end points for noninferiority testing were C

 of subcutaneous nivolumab vs IV nivolumab. The key secondary end point was ORR per BICR.

Final completion of the CheckMate-67T study is expected in January 2026.

FDA accepts BLA for subcutaneous nivolumab in solid tumors

There has been an explosion of treatment options in non–muscle invasive bladder cancer (NMIBC) in recent years, with even more coming down the pike. Many of these agents have demonstrated encouraging efficacy and manageable safety in clinical trials, meaning that patients and urologists must consider other factors when choosing between options.

, explains, this is a good challenge to have. The wealth of options will allow urologists to tailor treatment to both the individual’s preferences and, as we learn more, hopefully the patient’s specific disease characteristics.

He notes, “At the end of the day, it's going to be unlikely that we're going to use a single therapy for all of our patients. I think precision medicine is going to become more widespread as we understand who is going to respond best to which treatment, so I'm really excited to develop biomarkers that might help us guide us to what the best therapy is for each specific patient.”

Packiam is an associate professor of surgery at Rutgers Robert Wood Johnson Medical School as well as the director of clinical and translational research in urologic oncology at Rutgers Cancer Institute in New Jersey.

Vignesh Packiam, MD, outlines key considerations for choosing between options in NMIBC.

Specifically, Packiam says that long-term bladder symptoms associated with treatment, in addition to the short-term tolerability data, will be important for patients to understand as we gather more data.

“I think each therapy is going to have its own unique profile with how it affects the bladder in the long-term,” he stated.

Packiam also noted, “The other difference between various therapies that are out there is logistics, both in storage and administration. Some of these products have to be kept under certain temperature conditions, or they're given at a certain dosing regimen. Those details are going to become important to different patients as well.”

"At the end of the day, it's going to be unlikely that we're going to use a single therapy for all of our patients," says Vignesh T. Packiam, MD.

Recently recognized as a Surgical Review Corporation (SRC) Center of Excellence in Urology — a distinction earned by only 20 facilities nationwide —

 is setting a new standard for urologic care in the Erie region.

The recent expansion of AHN Saint Vincent Allied Urology was purposefully designed to enhance every aspect of the patient experience — from faster appointment scheduling to more comprehensive, on-site diagnostics. New offerings include 23 exam rooms, the region’s only Urodynamic testing suite, four dual procedure rooms, expanded telehealth and radiology services, and Erie’s only 3T MRI.

Among the advanced treatments available at AHN Saint Vincent is the

ProACT™ Adjustable Continence Device Therapy

— a new, minimally invasive, adjustable solution for men with mild to severe urinary stress incontinence, particularly those who are not ideal candidates for male slings or prefer to avoid an artificial urinary sphincter.

Michael Evankovich, MD, urologist at AHN Saint Vincent Allied Urology, is the only physician in the Erie region trained to perform the ProACT procedure.

ProACT involves the percutaneous placement of two small, adjustable balloons on either side of the urethra. Guided by fluoroscopy and cystoscopy, Dr. Evankovich navigates through two small perineal incisions to position the balloons without compromising the urethra, making the procedure well-suited for non-radiated patients with a history of prostatectomy or prior urethral surgery.

The balloons are adjusted gradually over time during quick, outpatient follow-up office visits to optimize continence based on the patient’s progress and level of improvement in dryness. The adjustments are generally simple and involve accessing small ports tunneled into the scrotum.

Urologists at AHN Saint Vincent collaborate across disciplines to manage urinary incontinence and related conditions. Initial treatment planning often includes assessing the effectiveness of lifestyle modifications or medication therapies either as standalone options or in combination with surgery.

If surgical intervention is required, AHN Saint Vincent’s expertise encompasses a broad spectrum of procedures — from minimally invasive endoscopic surgeries to more complex interventions, including:
