Primary Outcome Measures:
  • Successful Outcome According to Investigator's Global Assessment (IGA) [ Time Frame: baseline and 12 weeks ]
    The Investigator's Global Assessment (IGA) was performed at baseline and at 12 weeks. The IGA score is based on a 5-point acne severity scale from zero (clear) to 4 (severe). Successful outcome is at least a 2-point reduction in IGA score from baseline to 12 weeks.

  • Change From Baseline in Inflammatory Acne Lesion Count on the Face at 12 Weeks [ Time Frame: baseline and 12 weeks ]
    Acne lesions fall into 2 groups: inflammatory and non-inflammatory. The number of inflammatory acne lesions on the face was measured at baseline and after 12 weeks. The difference (change) was calculated.


Secondary Outcome Measures:
  • Change From Baseline in Non-inflammatory Acne Lesion Count on the Face at 12 Weeks [ Time Frame: baseline and 12 weeks ]
    Acne lesions fall into 2 groups: inflammatory and non-inflammatory. The number of non-inflammatory acne lesions on the face was measured at baseline and after 12 weeks. The difference (change) was calculated.

Study Completion Date: September 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Doxycycline hyclate (Doryx) Drug: Doxycycline hyclate (Doryx)
150mg/day, oral, delayed release tablets
Other Name: Doryx
Active Comparator: Doxycycline hyclate Drug: Doxycycline hyclate
100 mg/day, oral, tablets, immediate release

Detailed Description:
Efficacy of Doryx Delayed Release Tablets to doxycycline hyclate will be assessed using an Investigator's Global Assessment (IGA) score and the absolute change from baseline to 12 weeks in inflammatory lesion count in patients with moderate to severe facial acne vulgaris. Additionally, the absolute change from baseline to 12 weeks in non-inflammatory lesions count of Doryx Delayed Release Tablets compared to doxycycline hyclate will be evaluated.
