SIDE EFFECTS

Clinical Trials

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in 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 545 patients were exposed to BREXAFEMME in two clinical trials of women with VVC (Trial 1 and Trial 2). The women were treated with BREXAFEMME 300 mg (two 150 mg tablets) twice a day, 12 hours apart, for one day. The women were 18 to 76 years of age (mean 34 years); 69% were White and 28% were Black or African American; 18% were of Hispanic or Latina ethnicity.

The most frequently reported adverse reactions are presented in Table 1.

There were no serious adverse reactions and 2 out of 545 (0.4%) patients discontinued treatment with BREXAFEMME due to vomiting (1 patient) and dizziness (1 patient).

Vomiting 11 (2.0%) 2 (0.7%)
1 Includes abdominal pain, abdominal pain upper, abdominal pain lower, and abdominal discomfort
2 Includes dizziness and postural dizziness

Other Adverse Reactions

The following adverse reactions occurred in < 2% of patients receiving BREXAFEMME in Trial 1 and Trial 2: dysmenorrhea, flatulence, back pain, elevated transaminases, vaginal bleeding, rash/hypersensitivity reaction.

DRUG INTERACTIONS

Ibrexafungerp is a substrate of CYP3A4. Drugs that inhibit or induce CYP3A may alter the plasma concentrations of ibrexafungerp and affect the safety and efficacy of BREXAFEMME [see CLINICAL PHARMACOLOGY]

Table 2 Effect of Coadministered Drugs on Ibrexafungerp Pharmacokinetics:

Concomitant Drugs Effect on Ibrexafungerp Concentration Recommendation
Strong CYP3A inhibitors: (e.g., ketoconazole, itraconazole) Significantly increased Reduce the BREXAFEMME dosage [see DOSAGE AND ADMINISTRATIO]
Strong and Moderate CYP3A inducers: (e.g., rifampin, carbamazepine, phenytoin, St. John’s wort, long acting barbiturates, bosentan, efavirenz, or etravirine) Not studied in vivo or in vitro, but likely to result in significant reduction Avoid concomitant administration

Ibrexafungerp is an inhibitor of CYP3A4, P-gp and OATP1B3 transporter [(see CLINICAL PHARMACOLOGY]. However, given the short treatment duration for VVC, the effect of BREXAFEMME on the pharmacokinetics of substrates of CYP3A4, P-gp and OATP1B3 transporters is not considered to be clinically significant.
