Introduction: (New Antibiotic Tackles Drug-Resistant Gonorrhea in Trial)
A new antibiotic called zoliflodacin has shown promise in a clinical trial against drug-resistant gonorrhea, the second most common STI in the United States, with over 820,000 cases reported in 2022. The trial results were published in the New England Journal of Medicine on November 3, 2023.
Gonorrhea is caused by a bacteria called Neisseria gonorrhoeae, It can infect the genitals, rectum, and throat. which can develop resistance to antibiotics over time. The current standard of care for gonorrhea is a combination of two antibiotics, ceftriaxone and azithromycin. However, there have been some reports of gonorrhea strains that are resistant to both of these drugs.
Clinical Trial of Zoliflodacin for the Treatment of Gonorrhea:

Zoliflodacin was safe and well-tolerated, with no serious side effects reported
Safety and Tolerability:
Safety and tolerability were also secondary outcomes of the clinical trial. There were no serious side effects reported in either the zoliflodacin or ceftriaxone and azithromycin groups. This means that both treatments were safe and well-tolerated.
Overall, the results of the clinical trial were very positive. Zoliflodacin was as effective as the current standard of care for gonorrhea and was safe and well-tolerated. If zoliflodacin is approved by regulators, it would be a valuable new tool for clinicians and patients.
The clinical trial of zoliflodacin for the treatment of gonorrhea enrolled 930 patients at 16 sites in five countries. Patients were randomly assigned to receive either a single oral dose of zoliflodacin 3g or a ceftriaxone 500mg intramuscular injection plus azithromycin 1g oral single dose.
The primary outcome of the trial was the microbiological cure rate at 7 days after treatment, defined as the absence of viable Neisseria gonorrhoeae in the urethra, rectum, or throat. The secondary outcomes included the clinical cure rate at 7 days after treatment, defined as the resolution of signs and symptoms of gonorrhea, and the safety and tolerability of zoliflodacin.
The results of the trial were as follows:
Microbiological Cure Rate
Zoliflodacin: 94.8% (895% CI: 92.1%, 97.0%)
Ceftriaxone and azithromycin: 95.1% (895% CI: 92.4%, 97.2%)
The microbiological cure rate was non-inferior for zoliflodacin compared to ceftriaxone and azithromycin, meeting the pre-specified statistical margin of inferiority of 12%.
Clinical Cure Rate
Zoliflodacin: 100% (895% CI: 96.9%, 100.0%)
Ceftriaxone and azithromycin: 100% (895% CI: 97.0%, 100.0%)
The clinical cure rate was 100% in both groups.
Implications:
The development of zoliflodacin is a significant step forward in the fight against gonorrhea. The emergence of drug-resistant gonorrhea strains is a serious threat, and the development of new antibiotics is essential for staying ahead of the curve.
If zoliflodacin is approved by regulators, it would be a valuable tool for clinicians and patients. It would provide an alternative treatment option for people with gonorrhea infections that are resistant to the current standard of care.
Future Directions:
The next steps for zoliflodacin are to file for regulatory approval and to conduct additional clinical trials to evaluate its safety and efficacy in other populations, such as pregnant women and people with HIV.
Researchers are also looking at ways to prevent the development of drug-resistant gonorrhea strains. This includes developing new vaccines against Neisseria gonorrhoeae and developing new strategies to reduce the transmission of gonorrhea.
