6.1 Clinical Studies Experience Because clinical trials are conducted under prescribed conditions, adverse reaction rates observed in the clinical trial may not reflect the rates observed in practice.

The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse reactions that appear to be related to drug use for approximating rates.

The safety data presented in Table 1 (below) reflects exposure to clindamycin phosphate and tretinoin gel in 1,853 patients with acne vulgaris.

Patients were 12 years and older and were treated once daily for 12 weeks.

Adverse reactions that were reported in ≥ 1% of patients treated with clindamycin phosphate and tretinoin gel were compared to adverse reactions in patients treated with clindamycin phosphate 1.2% in vehicle gel, tretinoin 0.025% in vehicle gel, and the vehicle gel alone: Table 1: Adverse Reactions Reported in at Least 1% of Patients Treated with Clindamycin Phosphate and Tretinoin Gel: 12-Week Studies Clindamycin Phosphate and Tretinoin Gel Clindamycin Tretinoin Vehicle N=1853 N=1428 N=846 N=423 N (%) N (%) N (%) N (%) Note: Formulations used in all treatment arms were in the clindamycin phosphate and tretinoin vehicle gel.

In Studies 1 and 2, 1277 subjects enrolled with moderate to severe acne, 854 subjects treated with clindamycin phosphate and tretinoin gel and 423 treated with vehicle.

Analysis over the twelve week period demonstrated that cutaneous irritation scores for erythema, scaling, itching, burning, and stinging peaked at two weeks of therapy, and were slightly higher for the clindamycin phosphate and tretinoin-treated group, decreasing thereafter.

One open-label 12-month safety study for clindamycin phosphate and tretinoin gel showed a similar adverse reaction profile as seen in the 12-week studies.

Eighteen out of 442 subjects (4%) reported gastrointestinal symptoms.
