XACIATO

XACIATO vaginal gel contains clindamycin phosphate, a lincosamide antibacterial. The chemical name for clindamycin phosphate is methyl 7-chloro- 6,7,8-trideoxy-6-(1-methyl- trans-4-propyl-L-2-pyrrolidinecarboxamido)-1-thio-L- threo-(alpha)-D-galacto- octopyranoside 2-(dihydrogenphosphate). It has a molecular weight of 504.95, and the molecular formula is C 18 H 34 ClN 2 O 8 PS. The structural formula is represented below: XACIATO is a clear, colorless, viscous gel, which contains clindamycin at a concentration of 2%. A single-dose user-filled disposable applicator delivers 5 g of vaginal gel containing 100 mg of clindamycin (present as 119 mg of clindamycin phosphate). The gel also contains benzyl alcohol, citric acid monohydrate or citric acid anhydrous, poloxamer 407, purified water, sodium citrate dihydrate, and xanthan gum. structure

XACIATO is a lincosamide antibacterial indicated for the treatment of bacterial vaginosis in female patients 12 years of age and older. ( 1.1 ) 1.1 Bacterial Vaginosis XACIATO ® is indicated for the treatment of bacterial vaginosis in females 12 years and older [see Use in Specific Populations ( 8.1 ) and Clinical Studies ( 14 )] .

The recommended dosage of XACIATO is one applicatorful (5 g of vaginal gel containing 100 mg of clindamycin) administered once intravaginally as a single dose at any time of the day [see Clinical Studies ( 14 )] . Place the used tube with any remaining gel and used applicator in the container box and deposit in a trash container after use [see Instructions for Use ] . XACIATO is not for ophthalmic, dermal, or oral use. Administer one applicatorful (5 g of gel containing 100 mg of clindamycin) once intravaginally as a single dose at any time of the day. ( 2 ) Not for ophthalmic, dermal, or oral use. ( 2 )

History of hypersensitivity to clindamycin or lincomycin. ( 4.1 ) 4.1 Hypersensitivity XACIATO is contraindicated in individuals with a history of hypersensitivity to clindamycin or lincomycin. [see Adverse Reactions ( 6.2 )] .

The following clinically significant adverse reactions are described elsewhere in the labeling: Clostridioides difficile -Associated Diarrhea (CDAD) [see Warnings and Precautions ( 5.1 )] Use with Polyurethane Condoms [see Warnings and Precautions ( 5.2 )] Vaginal Candida Infections [see Warnings and Precautions ( 5.3 )] The most common adverse reactions reported in >2% of patients and at a higher rate in the XACIATO group than in the placebo group were vulvovaginal candidiasis and vulvovaginal discomfort.

In the placebo-controlled trial (Trial 1), 202 patients with bacterial vaginosis were treated with a single dose of XACIATO, and 103 patients were treated with a single dose of placebo gel. The median age of the patients in the trial was 35 years (range 15-59 years). The population was 56% Black or African American and 41% White. Persons of Hispanic or Latino ethnicity made up 25% of the population. A history of prior bacterial vaginosis was noted in 89% of the population. Most Common Adverse Reactions Adverse reactions were reported by 76/202 (38%) of patients who received XACIATO and 28/103 (27%) of patients who received placebo in Trial 1. Table 1 displays the most common adverse reactions (occurring in >2% of patients and at a higher rate in the XACIATO group than in the placebo group) in Trial 1. Table 1: Adverse Reactions Occurring in >2% of Patients Receiving XACIATO in Trial 1 Adverse Reaction XACIATO N=202 n (%) Placebo N=103 n (%) Vulvovaginal candidiasis 35 (17) 4 (4) Vulvovaginal discomfort Vulvovaginal discomfort includes the terms vulvovaginal pruritus, vulvovaginal burning sensation, vulvovaginal erythema, vulvovaginal dryness, and vulvovaginal discomfort. 13 (6) 5 (5) 6.2 Other Clindamycin Formulations XACIATO affords low peak serum levels and systemic exposure of clindamycin compared to an oral or intravenous dose of clindamycin [see Clinical Pharmacology ( 12.3 )] . Data from well-controlled trials directly comparing clindamycin administered orally to clindamycin administered vaginally are not available. The following additional adverse reactions and altered laboratory tests have been reported with the oral or parenteral use of clindamycin: Gastrointestinal: Abdominal pain, esophagitis, nausea, Clostridioides difficile -associated diarrhea [see Warnings and Precautions ( 5.1 )] . Hematopoietic: Transient neutropenia (leukopenia), eosinophilia, agranulocytosis, and thrombocytopenia have been reported. No direct etiologic relationship to concurrent clindamycin therapy could be made in any of these reports. Hypersensitivity Reactions: Maculopapular rash, vesiculobullous rash, and urticaria have been observed during drug therapy. Generalized mild to moderate morbilliform-like skin rashes are the most frequently reported of all adverse reactions. Cases of erythema multiforme, some resembling Stevens-Johnson syndrome, have been associated with clindamycin. A few cases of anaphylactoid reactions have been reported. Liver: Jaundice and abnormalities in liver function tests have been observed during clindamycin therapy. Musculoskeletal: Cases of polyarthritis have been reported. Renal: Acute kidney injury. Immune: Drug reaction with eosinophilia with systemic symptoms (DRESS) cases have been reported.

7.1 Neuromuscular Blocking Agents Systemic clindamycin has neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, it should be used with caution in patients receiving such agents.
