XACIATO: Package Insert and Label Information (Page 2 of 2)


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility


Long term studies in animals to evaluate carcinogenic potential have not been performed with XACIATO, or the active ingredient, clindamycin phosphate.


The genotoxic potential of clindamycin has been evaluated in a rat micronucleus test and an Ames Salmonella reversion test. Both tests were negative.

Impairment of Fertility

Fertility studies in rats treated vaginally with 2 mg/day clindamycin phosphate (0.1g/day XACIATO) or orally with 300 mg/kg/day (doses that are approximately equivalent to or 29-times the MRHD based on BSA comparisons, respectively) revealed no effects on fertility or mating ability.


The efficacy of XACIATO as a treatment of bacterial vaginosis (BV) in females 12 years of age and older was demonstrated in a randomized, double-blind, placebo-controlled clinical study (Trial 1, NCT04370548). A single dose of XACIATO (clindamycin phosphate vaginal gel, 2%) was compared to a single dose of placebo vaginal gel (hydroxyethylcellulose [HEC] Universal Placebo Gel) for the treatment of BV. Patients were evaluated at 3 timepoints: a Day 1 screening/randomization visit, a Day 7 to 14 Interim Assessment visit, and a Day 21 to 30 Test of Cure visit. The total study duration was up to approximately 1 month for each individual patient.

To be eligible, patients had to have a clinical diagnosis of BV defined as an off-white (milky or gray), thin, homogeneous discharge with minimal or absent pruritus and inflammation of the vulva and vagina, clue cells > 20% of the total epithelial cells on microscopic examination of the saline wet mount, vaginal secretion pH of > 4.5, and a fishy odor of the vaginal discharge with the addition of a drop of 10% KOH (i.e., a positive whiff test).

The 307 patients were randomized in a 2:1 ratio, with 204 in the XACIATO group and 103 in the placebo group. The modified Intent-To-Treat (mITT) Population excluded women with a positive test result for other concomitant vaginal or cervical infections at baseline, including a positive vaginal culture for Candida spp. or who had a baseline Nugent score of < 7.

Clinical Cure was defined as resolution of the abnormal vaginal discharge associated with BV, a negative 10% KOH whiff test, and clue cells < 20% of the total epithelial cells in the saline wet mount. Bacteriological Cure was defined as a Nugent score < 4. Therapeutic Cure was defined as the presence of both a Clinical Cure and Bacteriological Cure.

In the mITT population, a statistically significantly greater percentage of patients experienced Clinical Cure, Bacteriological Cure, and Therapeutic Cure at the Test of Cure (Day 21-30) visit in the XACIATO arm compared to placebo (Table 2). Statistically significant results for the endpoints were also achieved at the Interim Assessment visit (Day 7-14).

All P-values for differences between treatment groups were <0.001 (from Cochran-Mantel-Haenszel test with strata of study site and race — African American or all other races).

The percentage of patients with Clinical Cure at the Test of Cure visit was also significantly higher in the XACIATO group compared to the placebo group among the subsets of patients defined by prior episodes of bacterial vaginosis (≤ 3 episodes and >3 episodes in the previous 12 months) at 71.3% (72/101) for XACIATO and 39.1% (18/46) placebo, and 70.0% (14/20) for XACIATO and 23.1% (3/13) placebo, respectively.


XACIATO vaginal gel, 2% is a clear, colorless, viscous gel supplied in a carton containing one 25-gram tube of vaginal gel and one vaginal applicator. One single-dose, user-filled disposable applicator delivers 5 g of gel containing 100 mg of clindamycin. NDC number 81505-100-25.

Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F) [See USP Controlled Room temperature].


Advise the patient to read the FDA-approved patient labeling (Instructions for Use).

Vaginal Intercourse and Use with Vaginal Products

Instruct the patients not to engage in vaginal intercourse or use other vaginal products (such as tampons or douches) during treatment with XACIATO and for 3 days after using XACIATO.

Use with Polyurethane Condoms

Advise the patient that XACIATO may weaken polyurethane condoms. Therefore, use of polyurethane condoms concurrently or for 7 days following treatment with XACIATO is not recommended. During this time period polyurethane condoms may not be reliable for preventing pregnancy or for protecting against transmission of HIV and other sexually transmitted diseases. Latex or polyisoprene condoms should be used [see Warnings and Precautions (5.2)].

Vaginal Candida Infections

Inform the patient that vaginal yeast infections can occur following use of XACIATO and may require treatment with an antifungal drug [see Warnings and Precautions (5.3), Adverse Reactions (6.1)].

  • Do not use any medicine from the tube or applicator more than 1 time. The XACIATO gel is for 1 time (single-use) only.
  • Do not have vaginal sex or use vaginal products (such as tampons or douches) during treatment with XACIATO gel and for 3 days after using XACIATO gel.
  • Do not use polyurethane condoms during treatment with XACIATO gel and for 7 days after using XACIATO gel. XACIATO gel may weaken polyurethane condoms. Latex or polyisoprene condoms should be used.
  • If you have questions or if your vaginal symptoms do not go away, contact your healthcare provider.

How do I store XACIATO?

  • Store XACIATO gel at room temperature between 68° to 77°F (20° to 25°C).
  • Do not store in the refrigerator or freezer.

Store XACIATO gel and all medicines out of the reach of children.

You will need the following included supplies (see Figure A):

  • 1 single use tube containing the XACIATO gel
  • 1 empty applicator, to fill and deliver the single dose of medicine.
Step 1. Remove the applicator and tube from the container box.

Step 2. Open the tube.

  • Unscrew the cap from the tube (see Figure B1).
  • Puncture the seal on the tube using the pointed tip on the cap by pushing the cap straight onto the tube (see Figure B2).
  • Do not use the tube if it looks like it has been opened before.
  • Do not use the tube if the seal is damaged or broken.

Step 3. Fill the applicator.

  • While holding the applicator by the grip, screw the tip of the applicator (other end from the grip) onto the tube until it feels secure (see Figure C1).
  • Leave plunger inside the applicator.
  • Squeeze the tube from the bottom to push the XACIATO gel into the applicator (see Figure C2).
  • The XACIATO gel will push the plunger up as the applicator fills (see Figure C3).
  • Continue to fill the applicator until you see the black line on the plunger outside the applicator (see Figure C4).
  • Unscrew the filled applicator from the tube.
