Brief Summary:
PERIOGEN, containing rhPDGF and -beta-TCP, promotes gingival healing and corrects periodontal defects. This study will test the safety and efficacy of PERIOGEN in the treatment of periodontal disease

Condition or disease Intervention/treatment Phase
Intrabony Periodontal Defect Drug: PERIOGEN Drug: Beta TCP alone Phase 3

Detailed Description:
Sixty eligible patients with periodontal defect will randomly receive either beta-TCP implantation (control group) or PERIOGEN implantation, containing beta-TCP and rhPDGF (drug group). The specified primary and secondary end points related to efficacy and safety will be assessed during 6 months study period.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Study on the Efficacy and Safety of PERIOGEN in the Treatment of Periodontal Bone Defect - A Double-blind, Controlled, Randomised,Parallel,Multi-centre Study
Study Start Date : August 2007
Actual Primary Completion Date : August 2008
Actual Study Completion Date : August 2009

Arm Intervention/treatment
Experimental: Drug Group
Implantation of rhPDGF-BB (0.3 mg/ml) + β-TCP (0.5 g)
Active Comparator: Control group
Beta TCP alone
Drug: Beta TCP alone
Implantation of β-TCP (0.5 g) alone

Primary Outcome Measures :
  1. 1.Area under curve (AUC) of clinical attachment level (CAL) gain (0-24 weeks) 2.Extent of linear bone growth (LBG) and percentage of bone fill (%BF) at 6 months. [ Time Frame: 6 months ]

Secondary Outcome Measures :
  1. 1.Changes in CAL gain, probing depth and gingival recession at 3 and 6 months. 2.Incidence of adverse events. [ Time Frame: 3 and 6 months ]
