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.

 discusses his talk, “Barriers in Recruiting and Running Effective Clinical Trials in Independent Practices,” which was presented at the 

2025 American Urological Association (AUA) Annual Meeting

“If you look at national data within the United States, 80% of trials do not meet trial recruitment goals, 50% of trial sites enroll 0 to 1 patient, and 30% of patients drop out of trial. So, it's definitely a significant need that we have to address, and that's what we're hopefully going to address today,” Hafron explained.

Hafron is the chief medical officer and director of clinical research at Michigan Institute of Urology.

Jason M. Hafron, MD, CMO, discusses his talk, “Barriers in Recruiting and Running Effective Clinical Trials in Independent Practices."

Hafron also outlined several advantages to clinical trial enrollment in the independent practice setting. These include decreased travel times to care, close collaborations with institutional IRBs, and more. 

He added, "I think the key to success of enrolling a trial is a committed PI, or principal investigator, or a research champion that's dedicated to research but also has dedicated time within his or her schedule so that research isn't a burden but a priority."

Pearls & Perspectives: Sexual Health in MSM, with Joshua R. Gonzalez, MD

—a board-certified urologist and sexual medicine specialist based in Los Angeles, California—for a candid, inclusive conversation on sexual health in men who have sex with men (MSM) and how urologists can better meet the needs of this often-overlooked patient population.

Gonzalez shares how his fellowship under Irwin Goldstein, MD, helped him develop a broad, inclusive approach to sexual medicine, one that reflects the diversity of human experience across gender, orientation, and identity. Together, Pearlman and Gonzalez discuss how standard definitions of sexual dysfunction often rely on heteronormative models—especially around conditions like erectile dysfunction, premature ejaculation, and delayed ejaculation—and why a more nuanced clinical lens is necessary.

They dive into Gonzalez’s work as co-founder of 

, a sexual wellness company launched during the pandemic to meet real patient needs—starting with a supplement aimed at increasing ejaculatory volume. Gonzalez explains how this came directly from patient feedback, particularly from gay men, who described how volume contributed to pleasure, identity, and confidence. They also explore how this interest intersects with broader themes in men’s health—like sexual aging, performance expectations, and the underappreciated role of ejaculation in orgasmic satisfaction.

The conversation covers practical, case-based strategies for counseling MSM patients: how to ask about types of sex in a culturally sensitive way, how anal sex or topping can influence erection requirements, and how tools like intracavernosal injections and at-home phenylephrine can be incorporated into individualized treatment plans. They also discuss delayed ejaculation, sounding, edging, pelvic floor dysfunction, and the use of physical therapy and Botox to address pain with bottoming.

Later, they turn to procedural care—specifically penile girth enhancement using hyaluronic acid fillers—and how sexual practices may affect timing and technique. Gonzalez shares safety pearls on sounding, anal toys, and erection rings, emphasizing harm reduction over judgment, and urging clinicians to meet patients where they are.

In his closing message, Gonzalez challenges urologists to move beyond assumptions and create space for patients of all identities to talk openly about their sex lives. “Meet people where they’re at,” he says, “and give them the tools to have better sex—safely and confidently.”

Pearls & Perspectives: Expanding BPH care & patient choice, with Kevin Zorn, MD, at AUA 25

, host Amy Pearlman, MD, is joined by Kevin Zorn, MD, at the American Urological Association meeting in Las Vegas. They dive into the evolving landscape of 

 treatment—covering everything from personalized care in private practice to research collaborations that stretch far beyond traditional academic walls.

Zorn shares his journey from academia to opening BPH Canada, a center focused on comprehensive, individualized care for men dealing with prostate issues. He explains how moving out of an academic setting has actually allowed him to do 

 research, not less—thanks to flexible structures, external IRBs, and strong collaborations through groups like ICARUS.

They talk about the rapid expansion of BPH technologies and how Zorn’s approach is to offer the full range—not just what’s convenient or available in one setting. “No man should feel steered into a treatment because it’s the only one on the shelf,” he says. From UroLift to Aquablation and beyond, he outlines how shared decision-making is only meaningful when patients truly have options.

Zorn also previews his plenary talk on ejaculatory preservation, calling it a critical piece of informed consent that’s too often brushed aside. They cover what techniques can help preserve function, how to talk to patients about it, and why it’s time to ditch the “less mess” joke.

They close by discussing a supplement aimed at ejaculatory volume, real patient conversations about sex and expectations, and why old questionnaires might not capture the full story. For Zorn, it all comes back to one thing: treating patients like people, not procedures.

Urologists discuss innovative BPH treatments, emphasizing personalized care, and the importance of ejaculatory preservation.
