Number of Oral Ulcers at Day 85
The number of oral ulcers were counted at each visit and at the end of the treatment period (starting point was at baseline).
Time frame: Day 85
Pain of Oral Ulcers as Measured by Visual Analog Scale (VAS) at Day 85
A 100-mm VAS pain scale for oral ulcers was completed by the participant at timepoints specified in the protocol. Each 100-mm VAS was presented to the participant on a single sheet of bond paper. The participant was asked to draw a single line perpendicular to the VAS line at the point that represented the severity of their pain during the previous week, with 0 mm (the left-hand end of the scale) representing no pain and 100 mm (the right-hand end of the scale) representing the worst pain imaginable. The distance of the perpendicular line from the left-hand end of the scale was measured by ruler and recorded. When responding to a VAS item, participants specify their level of agreement to a statement by indicating a position along a continuous line between two end-points.
Time frame: Day 85
Pain of Genital Ulcers as Measured by Visual Analog Scale (VAS) Scores at Day 85
A 100-mm VAS pain scale for genital ulcers was completed by the participant at timepoints specified in the protocol. Each 100-mm VAS was presented to the participant on a single sheet of bond paper. The participant was asked to draw a single line perpendicular to the VAS line at the point that represented the severity of their pain during the previous week, with 0 mm (the left-hand end of the scale) representing no pain and 100 mm (the right-hand end of the scale) representing the worst pain imaginable. The distance of the perpendicular line from the left-hand end of the scale was measured by ruler and recorded. When responding to a VAS item, participants specify their level of agreement to a statement by indicating a position along a continuous line between two end-points.

Area under curve (AUC\^85) from Day 1 to Day 85 for the number of oral ulcers per day was determined using the trapezoidal rule and divided by the days between the date of the last observation and baseline. The AUC was determined using the LOCF approach to impute missing values.
Time frame: Day 1 to Day 85

Area Under the Curve (AUC) for the Number of Oral Plus Genital Ulcers From Day 1 to 85
Area under curve (AUC) from Day 1 to Day 85 (AUC\^85) for the number of oral plus genital ulcers per day was determined using the trapezoidal rule and divided by the days between the date of the last observation and baseline. The AUC was determined using the LOCF approach to impute missing values.

Percentage of Participants Who Were Oral Ulcer-free (Complete Response), or Whose Oral Ulcers Were Reduced by ≥ 50%, (Partial Response)
Comparison of the percentage of participants who were oral ulcer-free (complete response: free from active oral ulcers), or whose oral ulcers were reduced by ≥ 50%, (partial response) between the apremilast-treated and the placebo-treated groups. In this case, partial response also includes complete response.
Time frame: Baseline and Day 85
Change From Baseline in the Disease Activity as Measured by BD Current Activity Form/Index Score on Day 85
The Behçet's Disease Current Activity Index consists of three component scores, a participant's perception of disease activity, a clinician's overall perception of disease activity and a Behçet's Disease Current Activity Index Score. The score ranges from 0 to 12. A higher score indicates higher level of disease activity (worsening) and a negative change from baseline indicates improvement.
Time frame: Day 1 to Day 85 or to early termination visit
Number of Treatment Emergent Adverse Events (TEAE) During the Placebo Controlled Treatment Phase
A Treatment Emergent Adverse Event (TEAE) was defined as any AE occurring or worsening on or after the first treatment of any study drug, and within 28 days after the last dose of the last study drug.

Severity grades according to Common Terminology Criteria for Adverse Events v3.0 (CTCAE) on a 1-5 scale: Grade 1= Mild AE, Grade 2= Moderate AE, Grade 3= Severe AE, Grade 4= Life-threatening or disabling AE, Grade 5=Death related to AE.
