5 WARNINGS AND PRECAUTIONS
5.1 Colitis
Systemic absorption of clindamycin has been demonstrated following topical use of this product. Diarrhea, bloody diarrhea, and colitis (including pseudomembranous colitis) have been reported with the use of topical clindamycin. If significant diarrhea occurs, Clindamycin Phosphate Foam, 1% should be discontinued. [ See Adverse Reactions( 6.2). ]
Severe colitis has occurred following oral or parenteral administration of clindamycin with an onset of up to several weeks following cessation of therapy. Antiperistaltic agents such as opiates and diphenoxylate with atropine may prolong and/or worsen severe colitis. Severe colitis may result in death.
Studies indicate a toxin(s) produced by Clostridiais one primary cause of antibiotic-associated colitis. The colitis is usually characterized by severe persistent diarrhea and severe abdominal cramps and may be associated with the passage of blood and mucus. Stool cultures for Clostridium difficileand stool assay for C. difficiletoxin may be helpful diagnostically.
5.2 Irritation
Clindamycin Phosphate Foam, 1% can cause irritation. Concomitant topical acne therapy should be used with caution since a possible cumulative irritancy effect may occur, especially with the use of peeling, desquamating, or abrasive agents. If irritation or dermatitis occurs, clindamycin should be discontinued.
Avoid contact of Clindamycin Phosphate Foam, 1% with eyes, mouth, lips, other mucous membranes or areas of broken skin. If contact occurs, rinse thoroughly with water.
Clindamycin Phosphate Foam, 1% should be prescribed with caution in atopic individuals.

6 ADVERSE REACTIONS
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the 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 clinical practice.
A total of 439 subjects with mild to moderate acne vulgaris were treated once daily for 12 weeks with clindamycin phosphate foam, 1%.
The incidence of adverse reactions occurring in >1% of the subjects in clinical trials comparing clindamycin phosphate foam, 1% and its vehicle is presented in Table 1.

In a contact sensitization study, none of the 203 subjects developed evidence of allergic contact sensitization to clindamycin phosphate foam, 1%.
6.2 Postmarketing Experience
The following adverse reactions have been identified during post approval use of clindamycin phosphate foam, 1%: application site pain, application site erythema, diarrhea, urticaria, abdominal pain, hypersensitivity, rash, abdominal discomfort, nausea, seborrhea, application site rash, dizziness, pain of skin, colitis (including pseudomembranous colitis), and hemorrhagic diarrhea. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Abdominal pain and gastrointestinal disturbances, as well as gram-negative folliculitis, have also been reported in association with the use of topical formulations of clindamycin. Orally and parenterally administered clindamycin have been associated with severe colitis, which may end fatally.
-
7 DRUG INTERACTIONS
7.1 Erythromycin
Clindamycin Phosphate Foam, 1% should not be used in combination with topical or oral erythromycin-containing products due to possible antagonism to its clindamycin component. In vitrostudies have shown antagonism between these two antimicrobials. The clinical significance of this in vitroantagonism is not known.
-
8 USE IN SPECIFIC POPULATIONS
8.1 Pregnancy
Pregnancy Category B: There are no adequate and well-controlled studies in pregnant women treated with clindamycin phosphate foam, 1%. Clindamycin Phosphate Foam, 1% should be used during pregnancy only if the potential benefit clearly outweighs the potential risk to the fetus.
Reproduction studies have been performed in rats and mice using subcutaneous and oral doses of clindamycin phosphate, clindamycin hydrochloride and clindamycin palmitate hydrochloride. These studies revealed no evidence of fetal harm.
The highest dose used in the rat and mouse teratogenicity studies was equivalent to a clindamycin phosphate dose of 432 mg/kg. For a rat, this dose is 84 fold higher, and for a mouse 42 fold higher, than the anticipated human dose of clindamycin phosphate from clindamycin phosphate foam, 1% based on a mg/m 2comparison.
8.3 Nursing Mothers
It is not known whether clindamycin is excreted in human milk following use of Clindamycin Phosphate Foam, 1%. However, orally and parenterally administered clindamycin has been reported to appear in breast milk. Because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
If used during lactation and Clindamycin Phosphate Foam, 1% is applied to the chest, care should be taken to avoid accidental ingestion by the infant.
-
11 DESCRIPTION
Clindamycin Phosphate Foam, 1% contains clindamycin (1%) as clindamycin phosphate.
Clindamycin phosphate is a water-soluble ester of the semi-synthetic antibiotic produced by a 7(S)-chloro-substitution of the 7(R)-hydroxyl group of the parent antibiotic, lincomycin.
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-α-D- galacto- octopyranoside 2-(dihydrogen phosphate). The structural formula for clindamycin phosphate is represented below:
Clindamycin Phosphate Foam, 1% contains clindamycin (1%) as clindamycin phosphate, at a concentration equivalent to 10 mg clindamycin per gram in a thermolabile hydroethanolic foam vehicle consisting of cetyl alcohol, ethanol (58%), polysorbate 60, propylene glycol, purified water, and stearyl alcohol pressurized with a hydrocarbon (propane/butane) propellant.

12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Mechanism of action in acne vulgaris is unknown. [ See Microbiology (12.4)]
12.3 Pharmacokinetics
In an open label, parallel group study in 24 subjects with acne vulgaris, 12 subjects (3 male and 9 female) applied 4 grams of clindamycin phosphate foam, 1% once-daily for five days, and 12 subjects (7 male and 5 female) applied 4 grams of a clindamycin gel, 1%, once daily for five days. On Day 5, the mean C maxand AUC (0-12)were 23% and 9% lower, respectively, for clindamycin phosphate foam, 1% than for the clindamycin gel, 1%.
Following multiple applications of clindamycin phosphate foam, 1%, less than 0.024% of the total dose was excreted unchanged in the urine over 12 hours on Day 5.
12.4 Microbiology
No microbiology studies were conducted in the clinical trials with this product.
Clindamycin binds to the 50S ribosomal subunits of susceptible bacteria and prevents elongation of peptide chains by interfering with peptidyl transfer, thereby suppressing protein synthesis. Clindamycin has been shown to have in vitroactivity against Propionibacterium acnes( P. acnes), an organism that has been associated with acne vulgaris; however, the clinical significance of this activity against P. acneswas not examined in clinical studies with Clindamycin Phosphate Foam, 1%. P. acnesresistance to clindamycin has been documented.
Inducible Clindamycin Resistance
The treatment of acne with antimicrobials is associated with the development of antimicrobial resistance in P. acnesas well as other bacteria (e.g. Staphylococcus aureus, Streptococcus pyogenes). The use of clindamycin may result in developing inducible resistance in these organisms. This resistance is not detected by routine susceptibility testing.
Cross Resistance
Resistance to clindamycin is often associated with resistance to erythromycin.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
The carcinogenicity of a 1.2% clindamycin phosphate gel similar to Clindamycin Phosphate Foam, 1% was evaluated by daily application to mice for two years. The daily doses used in this study were approximately 3 and 15 times higher than the human dose of clindamycin phosphate from 5 milliliters of Clindamycin Phosphate Foam, 1%, assuming complete absorption and based on a body surface area comparison. No significant increase in tumors was noted in the treated animals.
A 1.2% clindamycin phosphate gel similar to Clindamycin Phosphate Foam, 1% caused a statistically significant shortening of the median time to tumor onset in a study in hairless mice in which tumors were induced by exposure to simulated sunlight.
Genotoxicity tests performed included a rat micronucleus test and an Ames Salmonella reversion test. Both tests were negative.
Reproduction studies in rats using oral doses of clindamycin hydrochloride and clindamycin palmitate hydrochloride have revealed no evidence of impaired fertility.
