Brief Summary:
Randomized, multi-center, double-blind, placebo-controlled 12-week study to assess the safety and efficacy of 3 doses of an oral formulation of Doxycycline oral tablets using the Investigator's Global Assessment (IGA) score and the absolute change from baseline in inflammatory lesion count in patients with moderate to severe facial acne vulgaris. Additionally, the absolute change from baseline in non-inflammatory and total lesions of the active study medication to placebo will be evaluated.

Condition or disease Intervention/treatment Phase
Acne Vulgaris Drug: Doxycycline 0.6 mg/kg/day Drug: Doxycycline 1.2 mg/kg/day Drug: Doxycycline 2.4 mg/kg/day Drug: Placebo Phase 2

Arm Intervention/treatment
Experimental: Doxycyline 0.6 mg/kg/day
Doxycycline dosed at 40 mg/day to subjects of appropriate weights
Drug: Doxycycline 0.6 mg/kg/day
doxycycline 40 mg/day, oral, 12 weeks

Experimental: Doxycycline 1.2 mg/kg/day
Doxycycline dosed at 80 mg/day to subjects of appropriate weights
Drug: Doxycycline 1.2 mg/kg/day
doxycycline 80 mg/day, 12 weeks

Experimental: Doxycycline 2.4 mg/kg/day
Doxycycline dosed at 160 mg/day to subjects of appropriate weights
Drug: Doxycycline 2.4 mg/kg/day
doxycycline 160 mg/day, 12 weeks

Placebo Comparator: Placebo Drug: Placebo
Placebo, 12 weeks

Primary Outcome Measures :
  1. Percentage Patients With Successful Outcome Investigator's Global Assessment (IGA) Score at Week 12, Intent to Treat (ITT) Population [ Time Frame: Week 12 ]
    IGA: 0/clear (clear skin no lesions, inflammatory or non-inflammatory), 1/almost clear (rare non-inflammatory lesion w/no more than 1 small inflammatory lesion), 2/mild (some non-inflammatory lesions with no more than a few inflammatory lesions, papules/pustules only, no nodular lesions), 3/moderate (up to many non-inflammatory lesions, some inflammatory lesions, no more than 1 small nodular lesion), 4/severe (many non-inflammatory & inflammatory lesions, no more than a few nodular lesions. Lower score improvement in score. Success=IGA decrease of at least 2 grades from baseline score.

  2. Absolute Change in Inflammatory Lesion Count From Baseline to Week 12, ITT Population [ Time Frame: Baseline to Week 12 ]
    Change derived as Baseline evaluation minus the Week 12 evaluation. Thus a positive change reflects a reduction in lesion count. Inflammatory Lesion Count includes nodules, papules and pustules.

Secondary Outcome Measures :
  1. Absolute Change From Baseline to Week 12 in NonInflammatory Lesion Count, ITT Population [ Time Frame: Baseline to Week 12 ]
    Noninflammatory Lesion Count includes open and closed comedones.

  2. Absolute Change From Baseline to Week 12 in Total Lesion Count, ITT Population [ Time Frame: Baseline to Week 12 ]
    Total Lesion Count is the sum of inflammatory and noninflammatory lesions.
