Last verified: November 2009
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 Intervention Phase
Intrabony Periodontal Defect Drug: PERIOGEN Drug: Beta TCP alone Phase 3

Study Type: Interventional
Study Design: 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

Further study details as provided by Virchow Group:

Primary Outcome Measures:
  • 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.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 ]

Enrollment: 60
Study Start Date: August 2007
Study Completion Date: August 2009
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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

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.

  3. Adequate keratinized tissue to permit complete tissue coverage of defect.
  4. Radiographic base of defect ≥3 mm coronal to the apex of the tooth.

Exclusion Criteria:

  1. Failure to maintain adequate oral hygiene (plaque index>2)
  2. Pregnant and lactating women
  3. History of oral cancer or HIV
  4. Periodontal surgery on treatment-targeted tooth within the last year.
  5. Tooth mobility greater than grade II.
  6. Study tooth exhibiting a class III furacation defect
  7. Localized aggressive periodontitis
  8. Radiographic signs of untreated acute infection at the surgical site
  9. Recent history of smoking more than 20 cigarettes/day
  10. Known allergy to E.coli-derived products
  11. Using an investigational therapy within the past 30 days.
