Product Labeling Index

1.1 Vulvovaginal Candidiasis

BREXAFEMME


® is indicated for the treatment of adult and post-menarchal pediatric females with vulvovaginal candidiasis (VVC).

1.2 Usage

If specimens for fungal culture are obtained prior to therapy, antifungal therapy may be instituted before the results of the cultures are known. However, once these results become available, antifungal therapy should be adjusted accordingly.

The recommended dosage of BREXAFEMME in adult and post-menarchal pediatric females is 300 mg (two 150 mg tablets) administered approximately 12 hours apart (e.g., in the morning and in the evening) for one day, for a total daily dosage of 600 mg (four 150 mg tablets). BREXAFEMME may be taken with or without food.

2.2 Dosage Modifications In Patients Due To Concomitant Use Of A Strong Inhibitor Of Cytochrome P450 Isoenzymes (Cyp) 3A

With concomitant use of a strong CYP3A inhibitor, administer BREXAFEMME 150 mg approximately 12 hours apart (e.g., in the morning and in the evening) for one day. No dosage adjustment is warranted in patients with concomitant use of a weak or moderate CYP3A inhibitor


[see Drug Interactions (7) and Clinical 


Pharmacology (12.3)].

2.3 Pregnancy Evaluation Prior To Initiating Treatment

Verify the pregnancy status  in females of reproductive potential prior to initiating treatment with BREXAFEMME


[see Contraindications (4), Warning and Precautions (5.1) and Use in Specific Populations (8.1, 8.3)].

3 Dosage Forms And Strengths

BREXAFEMME tablets are purple, oval, biconvex shaped tablets debossed with 150 on one side and SCYX on the other side containing 150 mg of ibrexafungerp.

4 Contraindications

  • BREXAFEMME is contraindicated in:Pregnancy
  • [see Warnings and Precautions (5.1), and
  • Use in Specific Populations (8.1, 8.3)]Patients with hypersensitivity to ibrexafungerp

5.1 Risk Of Fetal Toxicity

Based on findings from animal studies, BREXAFEMME use is contraindicated in pregnancy because it may cause fetal harm. In animal reproduction studies, ibrexafungerp administered orally to pregnant rabbits during organogenesis was associated with fetal malformations including absent forelimb(s), absent hindpaw, absent ear pinna, and thoracogastroschisis at dose exposures greater or equal to approximately 5 times the human exposure at the recommended human dose (RHD). Prior to initiating treatment with BREXAFEMME, verify the pregnancy status in females of reproductive potential. Advise females of reproductive potential to use effective contraception during treatment with BREXAFEMME and for 4 days after the last dose


 [see Use in Specific Populations (8.1, 8.3)].

6.1 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).

7 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 (12.3)] Table 2 Effect of Coadministered Drugs on Ibrexafungerp Pharmacokinetics:Concomitant Drugs Effect on Ibrexafungerp ConcentrationRecommendationStrong CYP3A inhibitors:


(e.g., ketoconazole, itraconazole)


Significantly increasedReduce the BREXAFEMME dosage 


[see Dosage and Administration (2.2)]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 administrationIbrexafungerp is an inhibitor of CYP3A4, P-gp and OATP1B3 transporter


[(see Clinical Pharmacology (12.3)]. 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.

8.1 Pregnancy

Risk SummaryBased on findings from animal studies, BREXAFEMME use is contraindicated in pregnancy because it may cause fetal harm. In pregnant rabbits, oral ibrexafungerp administered during organogenesis was associated with rare malformations including absent forelimb(s), absent hindpaw, absent ear pinna, and thoracogastroschisis at dose exposures greater or equal to approximately 5 times the human exposure at the RHD. Oral ibrexafungerp administered to pregnant rats during organogenesis was not associated with fetal toxicity or increased fetal malformations at a dose exposure approximately 5 times the human exposure at the RHD 


(see Data). Available data on BREXAFEMME use in pregnant women are insufficient to draw conclusions about any drug-associated risks of major birth defects, miscarriage, or other adverse maternal or fetal outcomes.


There is a pregnancy safety study for BREXAFEMME. If BREXAFEMME is inadvertently administered during pregnancy or if pregnancy is detected within 4 days after a patient receives BREXAFEMME, pregnant women exposed to BREXAFEMME and healthcare providers should report pregnancies to SCYNEXIS, Inc. at 1-888-982-SCYX (7299).DataAnimal DataIn a rat embryo-fetal study, ibrexafungerp was administered to pregnant rats by oral gavage from gestation days (GDs) 6 through 17 at doses of 10, 20, 35, and 50 mg/kg/day. No fetal malformations or changes in embryo-fetal survival or fetal body weights occurred with any of the doses of ibrexafungerp up to the high-dose of 50 mg/kg/day (approximately 5 times the RHD based on plasma AUC comparison). In an embryo-fetal study in rabbits, ibrexafungerp was administered by oral gavage at doses of 10, 25, and 50 mg/kg/day from GD 7 through GD 19. In the mid-dose group administered 25 mg/kg/day (approximately 5 times the RHD based on AUC comparison), fetal malformations, including absent ear pinna, craniorachischisis, thoracogastroschisis, trunk kyphosis, absent forelimbs, absent forepaws, and absent hindpaw occurred in a single fetus. Malformations including absent hindpaw and anencephaly occurred with an increased litter incidence in the high-dose group of 50 mg/kg/day (approximately 13 times the RHD based on AUC comparison), and other malformations occurred in single fetuses and litters including absent ear pinna, thoracogastroschisis, absent forelimb, and absent thyroid gland. No changes in embryo-fetal survival or fetal body weights were observed with any of the ibrexafungerp doses, and fetal malformations were not observed with the 10 mg/kg/day dose of ibrexafungerp (approximately 2 times the RHD based on AUC comparison).In a pre-postnatal study in rats, ibrexafungerp was administered by oral gavage from GD 6 through the lactation period until lactation day 20 in maternal doses of 10, 20, 35, and 50 mg/kg/day. No maternal toxicity or adverse effects on the survival, growth, behavior, or reproduction of first-generation offspring occurred with any of the ibrexafungerp doses up to the high dose of 50 mg/kg/day (approximately 5 times the RHD based on AUC comparison).

8.2 Lactation

Risk SummaryThere are no data on the presence of ibrexafungerp in either human or animal milk, the effects on the breast-fed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for BREXAFEMME and any potential adverse effects on the breastfed child from BREXAFEMME or from the underlying maternal condition.

8.3 Females And Males Of Reproductive Potential

Based on animal data, BREXAFEMME may cause fetal harm when administered to a pregnant female


[see Use in Specific Populations (8.1)].


Pregnancy TestingVerify the pregnancy status in females of reproductive potential prior to initiating treatment with BREXAFEMME


[see Dosage and Administration (2.3), Contraindications (4) and Use in Specific Populations (8.1)].


ContraceptionFemalesAdvise females of reproductive potential to use effective contraception during treatment with BREXAFEMME and for 4 days after the last dose.

8.4 Pediatric Use

The safety and effectiveness of BREXAFEMME for treatment of VVC have been established in post-menarchal pediatric females. Use of BREXAFEMME in post-menarchal pediatric patients is supported by evidence from adequate and well-controlled studies of BREXAFEMME in adult non-pregnant women with additional safety data from post-menarchal pediatric females 


[see Adverse Reactions (6.1) and Clinical Studies (14.1)]. 


The safety and effectiveness of BREXAFEMME have not been established in pre-menarchal pediatric females.

8.5 Geriatric Use

Clinical studies with ibrexafungerp did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects. No clinically meaningful differences in the pharmacokinetics of ibrexafungerp were observed in geriatric patients compared to younger adults 


[see Clinical Pharmacology (12.3)].

10 Overdosage

There is no experience with overdosage of BREXAFEMME.  There is no specific antidote for ibrexafungerp. Treatment should be supportive with appropriate monitoring.

11 Description

BREXAFEMME, available as an oral tablet, contains ibrexafungerp citrate, a triterpenoid antifungal agent. Ibrexafungerp is designated chemically as (1S,4aR,6aS,7R,8R,10aR,10bR,12aR,14R,15R)-15-[(2R)-2-amino-2,3,3-trimethylbutoxy]-1,6a,8,10a-tetramethyl-8-[(2R)-3-methylbutan-2-yl]-14-[5-(pyridine-4-yl)-1H-1,2,4-triazol-1-yl]-1,6,6a,7,8,9,10,10a,10b,11,12,12a-dodecahydro-2H,4H-1,4a-propanophenanthro[1,2-c]pyran-7-carboxylic acid compound with 2-hydroxypropane-1,2,3-tricarboxylic acid (1:1) with an empirical formula of C

7BREXAFEMME tablet for oral administration is a purple, oval, biconvex shaped, film-coated tablet containing 189.5 mg of ibrexafungerp citrate equivalent to 150 mg of ibrexafungerp. In addition to the active ingredient, the tablet formulation contains butylated hydroxyanisole, colloidal silicon dioxide, crospovidone, magnesium stearate, mannitol, and microcrystalline cellulose. The tablet film-coating contains FD&C Blue #2, FD&C Red #40, hydroxypropyl cellulose, hydroxypropylmethyl cellulose 2910, talc and titanium dioxide.

12.1 Mechanism Of Action

Ibrexafungerp is a triterpenoid antifungal drug


[see Microbiology (12.4)].

12.2 Pharmacodynamics

Ibrexafungerp exposure-response relationships and the time course of pharmacodynamic response are unknown.  Cardiac ElectrophysiologyAt a concentration of 5 times or greater than that achieved after a single day 300 mg twice daily dose, ibrexafungerp does not prolong the QTc interval to any clinically relevant extent.

12.3 Pharmacokinetics

In healthy subjects, ibrexafungerp area under the curve (AUC) and maximal concentration (C


max) increased approximately dose-proportionally following single dose administration from 10 to 1600 mg (0.02 to 2.67 times the approved recommended daily dose) and multiple-dose administration from 300-800 mg (0.50 to 1.33 times the approved recommended daily dose).  


Based on a population pharmacokinetic analysis in patients with VVC, the model predicts that 300 mg twice a day for 2 doses achieves a mean (%CV) AUC


0-24 exposure of 6832 (15%) ng•hr/mL and C


max of 435 (15%) ng/mL under fasted conditions and a mean AUC


0-24 exposure of 9867 (15%) ng•h/mL and C


max of 629 (15%) ng/mL under fed conditions.


AbsorptionAfter oral administration of BREXAFEMME in healthy volunteers, ibrexafungerp generally reaches maximum plasma concentrations 4 to 6 hours after single and multiple dosing.Effect of FoodFollowing administration of BREXAFEMME to healthy volunteers, the ibrexafungerp C


max increased 32% and the AUC increased 38% with a high fat meal (800-1000 calories; 50% fat), compared to fasted conditions. This exposure change is not considered clinically significant 


[see Dosage and Administration (2.1)]. 


DistributionThe mean steady state volume of distribution (Vss) of ibrexafungerp is approximately 600 L. Ibrexafungerp is highly protein bound (greater than 99%), predominantly to albumin. Animal studies demonstrate a 9-fold higher exposure in vaginal tissue than in blood.EliminationIbrexafungerp is eliminated mainly via metabolism and biliary excretion. The elimination half-life is approximately 20 hours.MetabolismIn vitro studies show that ibrexafungerp undergoes hydroxylation by CYP3A4, followed by glucuronidation and sulfation of a hydroxylated inactive metabolite. ExcretionFollowing oral administration of radio-labeled ibrexafungerp to healthy volunteers, a mean of 90% of the radioactive dose (51% as unchanged ibrexafungerp) was recovered in feces and 1% was recovered in urine.Specific PopulationsGeriatric PatientsA comparison of elderly healthy males and females (range of 65 to 76 years) with young healthy males (range of 20 to 45 years) showed that the geometric means ratio (GMR) of pooled elderly males and females / young males for the AUC


0-inf (90% CI) was 1.39 (1.19, 1.62). Dose adjustment for age is not required.


Drug Interaction StudiesIbrexafungerp is a substrate of CYP3A4 and P-gp. In vitro, ibrexafungerp is an inhibitor of CYP2C8, CYP3A4, P-gp transporter, and OATP1B3 transporter. Ibrexafungerp is not an inducer of CYP3A4.The effect of coadministration of drugs on the pharmacokinetics of ibrexafungerp and the effect of ibrexafungerp on the pharmacokinetics of coadministered drugs were studied in healthy subjects.Effect of Coadministered Drugs on Ibrexafungerp PharmacokineticsStrong 


CYP3A4 Inhibitor:


Ketoconazole (400 mg once daily for 15 days), a strong CYP3A4 and P-gp inhibitor, increased the ibrexafungerp AUC by 5.8-fold and C


max by 2.5-fold


[see Drug Interactions (7)]. Moderate CYP3A4 Inhibitor: Diltiazem (240 mg once daily for 15 days) increased the ibrexafungerp AUC by 2.5-fold and C


max by 2.2-fold. This exposure change is not considered clinically significant at the approved recommended dosage for VVC.


Proton Pump Inhibitor: Pantoprazole (40 mg once daily for 5 days) decreased ibrexafungerp AUC by approximately 25% and C


max by 22%. This exposure change is not considered clinically significant at the approved recommended dosage for VVC.


Effect of Ibrexafungerp on the Pharmacokinetics of Coadministered Drugs The effects of ibrexafungerp on substrates of CYP2C8, CYP3A4, P-gp, and OATP1B3 transporters were evaluated in studies that included loading doses of ibrexafungerp of 1250 to 1500 mg (2.1 to 2.5 times the approved recommended daily dose) for two days followed by 750 mg (1.25 times the approved recommended daily dose) once daily for 3-7 days.CYP2C8 substrates: Ibrexafungerp did not increase the AUC


0-inf or C


max of rosiglitazone, a moderate sensitive CYP2C8 substrate.


CYP3A4 substrates: Ibrexafungerp resulted in 1.4-fold increase in the AUC


0-inf and no effect on the C


max of the sensitive CYP3A4 and P-gp substrate tacrolimus.


P-gp substrates: Ibrexafungerp resulted in a 1.4-fold increase in the AUC


0-48 and a 1.25-fold increase in the C


max of the P-gp substrate dabigatran.


OATP1B3 transporters: Ibrexafungerp resulted in a 2.8-fold increase in the AUC


0-24 and a 3.5 fold increase in the C


max of the OATP1B3 transporter substrate pravastatin.

12.4 Microbiology

Mechanism of ActionIbrexafungerp, a triterpenoid antifungal agent, inhibits glucan synthase, an enzyme involved in the formation of 1,3-β-D-glucan, an essential component of the fungal cell wall.Ibrexafungerp has concentration-dependent fungicidal activity against


Candida species as measured by time kill studies. Ibrexafungerp retains in vitro antifungal activity when tested at pH 4.5 (the normal vaginal pH).


ResistanceThe potential for resistance to ibrexafungerp has been evaluated in vitro and is associated with mutations of the


fks-2 gene; the clinical relevance of these findings is unknown. Ibrexafungerp retains activity against most fluconazole resistant


Candida spp.


Interaction with Other AntifungalsIn vitro


 studies have not demonstrated antagonism between ibrexafungerp and azoles or echinocandins.


Antimicrobial ActivityIbrexafungerp has been shown to be active against most isolates of the following microorganism both in vitro and in clinical infections


[see Indications and Usage (1)]:


Candida albicansThe following in vitro data are available, but their clinical significance is unknown. Ibrexafungerp has in vitro activity against most isolates of the following microorganisms:Candida auris Candida dubliniensisCandida glabrata 


Candida guilliermondii Candida keyfrCandida kruseiCandida lusitaniae 


Candida parapsilosisCandida tropicalis

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

CarcinogenesisTwo-year carcinogenicity studies of ibrexafungerp have not been performed. MutagenesisNo mutagenic or clastogenic effects were detected in an in vitro bacterial reverse mutation assay, an in vitro chromosomal aberration assay, and an in vivo bone marrow micronucleus assay in rats.Impairment of Fertility In a male and female fertility study in rats, ibrexafungerp was administered to male rats by oral gavage in doses of 10, 20, 40, and 80 mg/kg/day for 28 days before mating and throughout mating and to female rats for 15 days before mating, during mating, and until gestation day (GD) 6. Ibrexafungerp did not impair fertility in either sex at any dose up to the highest dose of 80 mg/kg/day (approximately 10 times the RHD based on AUC comparison).

14 Clinical Studies

Two randomized placebo-controlled clinical trials (Trial 1, NCT03734991 and Trial 2, NCT03987620) with a similar design were conducted to evaluate the safety and efficacy of a single day of BREXAFEMME 600 mg (two 150 mg tablets per dose, administered 12 hours apart) for the treatment of VVC. Non-pregnant post-menarchal females with a diagnosis of VVC were eligible. A diagnosis of VVC was defined as (a) minimum composite vulvovaginal signs and symptoms (VSS) score of ≥4 with at least two signs or symptoms having a score of 2 (moderate) or greater; (b) positive microscopic examination with 10% KOH in a vaginal sample revealing yeast forms (hyphae/pseudohyphae) or budding yeasts, and (c) normal vaginal pH (≤4.5). The total composite VSS score was based on the vulvovaginal signs (erythema, edema, excoriation) and vulvovaginal symptoms (itching, burning, or irritation) where each was scored as 0= absent, 1= mild, 2= moderate, or 3= severe. Study visits included the test of cure (TOC, Day 8 to 14) visit and a follow-up (Day 21 to 29) visit. The modified intent to treat (MITT) population included randomized subjects with a baseline culture positive for
Candida species who took at least 1 dose of study medication.
Trial 1 was conducted in the United States. The MITT population consisted of 190 patients treated with BREXAFEMME and 100 patients treated with placebo. The average age was 34 years (range 17-67 years), with 91% less than 50 years. Fifty-four percent (54%) were White and 40% were Black or African American, 26% were of Hispanic or Latino ethnicity. The average BMI was 30 and 9% had a history of diabetes. The median VSS score at baseline was 9 (range 4-18). The majority (92%) of the subjects were culture-positive with
C. albicans.
Trial 2 was conducted in the United States (39%) and Bulgaria (61%). The MITT population consisted of 189 patients treated with BREXAFEMME and 89 patients treated with placebo. The average age was 34 years (range 18-65 years), with 92% less than 50 years. Eighty-one percent (81%) were White and 19% were Black or African American, 10% were of Hispanic or Latino ethnicity. The average BMI was 26 and 5% had a history of diabetes. The median VSS score at baseline was 10 (range 4-18). The majority (89%) of the subjects were culture-positive with
C. albicans.
Efficacy was assessed by clinical outcome at the TOC visit. A complete clinical response was defined as the complete resolution of signs and symptoms (VSS score of 0). Additional endpoints included a negative culture for
Candida spp. at the TOC visit, and clinical outcome at the follow-up visit.
Statistically significantly greater percentages of patients experienced a complete clinical response at TOC, negative culture at TOC, and complete clinical response at follow-up with treatment with BREXAFEMME compared to placebo.
