Clindesse

CLINDESSE- clindamycin phosphate cream
Padagis Israel Pharmaceuticals Ltd

1 INDICATIONS AND USAGE

1.1 Treatment of Bacterial Vaginosis

Clindesse is indication for the treatment of bacterial vaginosis (formerly referred to as Haemophilus vaginitis, Gardnerellavaginitis , nonspecific vaginitis, Corynebacteriumvaginitis , or anaerobic vaginosis) in non-pregnant women.

2 DOSAGE AND ADMINISTRATION

The recommended dose is the complete contents of a single pre-filled applicator containing 5 g of Clindesse cream administered once intravaginally at any time of the day.

Not for ophthalmic, dermal, or oral use.

3 DOSAGE FORMS AND STRENGTHS

Clindesse is an intravaginal cream containing clindamycin phosphate 2%. Each pre-filled, single-dose applicator delivers approximately 5 g of cream containing approximately 100 mg of clindamycin.

4 CONTRAINDICATIONS

4.1 Hypersensitivity

Do not administer Clindesse to individuals with a history of hypersensitivity to clindamycin or other lincosamides. Reported reactions to other formulations of clindamycin include rashes, urticaria, erythema multiforme, and anaphylactoid reactions [see Adverse Reactions (6.2) ].

4.2 History of Bowel Disease

Do not administer Clindesse to patients with regional enteritis, ulcerative colitis, or a history of Clostridium difficile -associated diarrhea.

5 WARNINGS AND PRECAUTIONS

5.1 Clostridium difficile -Associated Diarrhea (CDAD)

Clostridium difficile -associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including clindamycin, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated [see Adverse Reactions (6.2 ].

5.2 Use with Condoms and Vaginal Contraceptive Diaphragms

This cream contains mineral oil that may weaken latex or rubber products such as condoms or vaginal contraceptive diaphragms. Therefore, the use of such barrier contraceptives is not recommended concurrently or for 5 days following treatment with Clindesse. During this time period, condoms may not be reliable for preventing pregnancy or for protecting against transmission of HIV and other sexually transmitted diseases.

6 ADVERSE REACTIONS

6.1 Clinical Study 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 practice.

The data described below reflect exposure to Clindesse in 368 patients. Clindesse was studied in three clinical studies: placebo-controlled (n=85), active-controlled (n=263), and single-arm (n=20). The population was female, aged 18 to 78, who were diagnosed with bacterial vaginosis. Patient demographics in the trials were 51% Caucasian, 36% Black, 10% Hispanic, and 3% Asian, other or unknown. All patients received 100 mg clindamycin phosphate cream intravaginally in a single dose.

Of the 368 women treated with a single dose of Clindesse, 1.6% of the patients discontinued therapy due to adverse reactions. Adverse reactions occurred in 126 of 368 patients (34%) treated with Clindesse and in 32 of 85 patients (38%) treated with placebo.

Adverse reactions occurring in ≥2% of patients receiving Clindesse in the placebo-controlled clinical trial are shown in Table 1.

N = number of patients in intent-to-treat population

n (%) = number and percentage of patients with reported adverse reaction

NOS = not otherwise specified

The use of clindamycin may result in the overgrowth of non-susceptible fungal organisms in the vagina and may require antifungal treatment

Other reactions reported by <1% of those women treated with Clindesse include:

Dermatologic:

Pruritic rash

Gastrointestinal:

Diarrhea, vomiting

General:

Fatigue

Immune System:

Hypersensitivity

Nervous System:

Dizziness

Reproductive System:

Dysfunctional uterine bleeding, dysmennorrhea, intermenstrual bleeding, pelvic pain, vaginal burning, vaginal irritation, vulvar erythema, vulvitis, vulvovaginal discomfort, vulvovaginal dryness, vulvovaginitis

6.2 Other Clindamycin Formulations

Clindesse affords minimal peak serum levels and systemic exposure (AUCs) of clindamycin compared to an oral or intravenous dose of clindamycin [see Clinical Pharmacology (12.1) ]. 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, Clostridium 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: Although no direct relationship of clindamycin to renal damage has been established, renal dysfunction as evidenced by azotemia, oliguria, and/or proteinuria has been observed in rare instances.

6.3 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of Clindesse. 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.

Dermatologic: Rash

Gastrointestinal: Hematochezia

Reproductive System: Vaginal erythema, vulvovaginal pruritis, vaginal discharge, vaginal swelling, vaginal bleeding, vaginal pain

7 DRUG INTERACTIONS

No formal drug interaction studies have been conducted for Clindesse.

7.1 Neuromuscular Blocking Agents

Orally or intravenously administered 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.
