  Purpose
This study aims to assess the long term (three years) ability of ASU (Avocado Soya unsaponifiable) to slow the decrease of radiographic JSW (Joint Space Width) in hip osteoarthritis (OA). This is a randomized, double blind, comparative, parallel group study versus placebo.

Condition Intervention Phase
Hip Osteoarthritis Drug: ASU Phase 3

Study Type: Interventional
Official Title: Evaluation of the Structure-modifying Effect and Safety of Avocado-Soybean Unsaponifiable (Piascledine 300) in Hip Osteoarthritis (OA) a 3 Years Multicenter Randomized, Double Blind, Placebo Controlled Trial

Primary Outcome Measures:
  • The main criterion of efficacy is the change of JSW between baseline and end point. JSW is measured on the narrowest joint on pelvic or target hip X ray by blinded reader.

Study Start Date: December 1999
Study Completion Date: September 2006
Primary Completion Date: September 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ASU (Avocado Soybean Unsaponifiable) Drug: ASU

Detailed Description:

Inclusion criteria:

Primary hip OA, fulfilling ACR criteria, patient over 45 y, painful > 1 year, Lequesne's index > or equal to 3, with minimum JSW at the target hip > 1 mm and < 4 mm on pelvic radiograph.

Primary criterion of efficacy:

The main criterion of efficacy is the change of JSW between baseline and end point. JSW is measured on the narrowest joint on pelvic or target hip X ray by blinded reader.

Randomisation is stratified according JSW at baseline (< 2,5 mm or > or equal to 2,5 mm).

Statistical analysis:

The Full Analysis Set (FAS) is defined by patients with at least one baseline value and one post baseline value.

The main analysis is scheduled on FAS using a Missing At Random (MAR)with a multiple model repeated measure (MMRM)to take in account missing value.

SAP (Statistical Analysis Plan) schedule to analyse JSW change as quantitative variable using an ANCOVA and as qualitative variable (progressors defined as JSW loss upper than 0,5 mm) using Mantel Haentzel test.
