Zoliflodacin: uses, dosing, side effects & brands

The following clinically significant adverse reactions are discussed in the Warnings and Precautions section of the labeling: Hypersensitivity Reactions [see Warnings and Precautions (5.4) ] The most common adverse reactions including laboratory abnormalities (incidence ≥2%) with NUZOLVENCE are neutropenia, headache, leukopenia, dizziness, nausea, and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Entasis Therapeutics, Inc. at 1-800-651-3861 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. A total of 782 patients received a 3 g dose of zoliflodacin across all phases of clinical trials. The safety of NUZOLVENCE was evaluated in a phase 3, randomized, open-label, active-controlled, multicenter, multinational trial (NCT03959527) (Trial 1). In total, 927 patients with suspected uncomplicated gonorrhea due to N. gonorrhoeae were randomized (2:1) and treated with either a single oral 3 g dose of NUZOLVENCE (N=619) or a combination of a single 500 mg intramuscular dose of ceftriaxone and a single 1 g oral dose of azithromycin (N=308) [see Clinical Studies (14) ] .

NUZOLVENCE is contraindicated in: patients with a known history of hypersensitivity to NUZOLVENCE [see Warnings and Precautions (5.4) ] . patients who use concomitant moderate or strong CYP3A4 inducers because concomitant use is predicted to result in decreased plasma concentrations of zoliflodacin and may reduce the efficacy of NUZOLVENCE [see Drug Interactions (7.1) and Clinical Pharmacology (12.3) ]. Known history of hypersensitivity to NUZOLVENCE. ( 4 ) Concomitant use with moderate or strong CYP3A4 inducers because this is predicted to result in decreased plasma concentrations of zoliflodacin and may reduce NUZOLVENCE efficacy. ( 4 , 7.1 )

7.1 Effect of Other Drugs on NUZOLVENCE Moderate and Strong CYP3A4 Inducers Concomitant use of moderate or strong inducers of CYP3A4 with NUZOLVENCE is contraindicated [see Contraindications (4) ] . Zoliflodacin is a CYP3A4 substrate. Moderate and strong CYP3A4 inducers are predicted to result in decreased plasma concentrations of zoliflodacin and may reduce NUZOLVENCE efficacy [see Clinical Pharmacology (12.3) ] .
