Zoliflodacin

Contraindications

4 CONTRAINDICATIONS 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 )

Pregnancy & Breastfeeding

8.1 Pregnancy Risk Summary Based on findings from animal studies, NUZOLVENCE may cause fetal malformations or increased embryo-fetal loss when administered to a pregnant female. In pregnant mice, repeat oral administration of zoliflodacin during organogenesis was associated with fetal malformations (exencephaly) and increased embryo-fetal loss at AUC exposures 1.6-fold the MRHD and decreased fetal weights at 2.9-fold the MRHD. In pregnant rats, zoliflodacin administration resulting in AUC exposures 8.5-fold the MRHD increased embryo-fetal loss, and exposures 3.2-fold the MRHD decreased fetal weights. There was no effect on embryo-fetal survival at exposures 5.5-fold the MRHD to zoliflodacin in pregnant rats. When zoliflodacin was administered to rats throughout pregnancy, parturition, and lactation, no effects on pup survival, birth weight, or growth were observed at maternal exposures up to 2.4-fold the MRHD (see Data ). There are no human data on NUZOLVENCE use in pregnancy to evaluate the drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Advise pregnant females about the potential risk to the fetus with maternal exposure to NUZOLVENCE [see Warnings and Precautions (5.1) and Use in Specific Populations (8.3) ] . A postmarketing descriptive pregnancy safety study is available for NUZOLVENCE. If exposure occurs during pregnancy, pregnant females or their healthcare providers should report the pregnancy to Entasis Therapeutics at 1-800-651-3861. The background risk of major birth defects and miscarriage in the indicated population is unknown. All pregnancies have a background risk of birth defects, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data In pregnant mice, repeat oral administration of zoliflodacin at 250, 500, and 1000 mg/kg/day
