OBJECTIVE: Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400 ... [more ▼]

OBJECTIVE: Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400) (equivalence study) and vs placebo (superiority study) during 3 months, in patients with knee osteoarthritis (OA). DESIGN: Comparative, double-blind, randomized, multicenter study, including 353 patients of both genders over 45 years with knee OA. Minimum inclusion criteria were a Lequesne index (LI) >/= 7 and pain >/= 40 mm on a visual analogue scale (VAS). LI and VAS were assessed at baseline and after 1-3 months. Equivalence between CS was tested using the per-protocol procedure and superiority of CS vs placebo was tested using an intent-to-treat procedure. RESULTS: After 3 months of follow-up, no significant difference was demonstrated between the oral daily single dose of CS 1200 formulation and the three daily capsules of CS 400. Patients treated with CS 1200 or CS 3*400 were significantly improved compared to placebo after 3 months of follow-up in terms of LI (<0.001) and VAS (P < 0.01). No significant difference in terms of security and tolerability was observed between the three groups. CONCLUSION: This study suggests that a daily administration of an oral sachet of 1200 mg of chondroitin 4&6 sulfate allows a significant clinical improvement compared to a placebo, and a similar improvement when compared to a regimen of three daily capsules of 400 mg of the same active ingredient.

Objectives: To compare the efficacy and safety of lumiracoxib with placebo and celecoxib for osteoarthritis (OA) in a 13 week, multicentre, randomised, double blind study. Methods: After a 327 day washout period for non-steroidal anti-inflammatory drugs, 1702 patients with knee OA were randomised to lumiracoxib 200 or 400 mg once daily (od), celecoxib 200 mg od, or placebo (2:2:2:1). A visual analogue scale (VAS) pain intensity greater than or equal to40 mm was required. Primary efficacy variables were OA pain intensity (VAS mm) in the target knee, patient's global assessment of disease activity (VAS mm), and WOMAC pain subscale and total scores at 13 weeks. OA pain intensity, patient's and physician's global assessment of disease activity, and WOMAC (total and all subscale scores) were analysed by visit as secondary variables. Results: Lumiracoxib showed significant improvements in all primary and secondary variables compared with placebo. Lumiracoxib 200 mg od and celecoxib 200 mg od achieved similar improvements in OA pain intensity and functional status. Lumiracoxib 400 mg od demonstrated better efficacy for OA pain intensity and patient's global assessment of disease activity at weeks 2, 4, and 8 and similar efficacy at week 13 compared with celecoxib 200 mg od. The incidence of adverse events (AEs), serious AEs, and discontinuations due to AEs was similar in each group. Conclusion: Lumiracoxib demonstrated significant improvement in OA pain intensity, patient's global assessment of disease activity, and the WOMAC pain subscale and total scores compared with placebo. Lumiracoxib was well tolerated in this study, with overall tolerability similar to that of placebo and celecoxib. [less ▲]

Objective: To investigate the efficacy and tolerability of a 3-month duration, twice a-year, intermittent treatment with oral chondroitin sulfate (CS) in knee osteoarthritis (OA) patients. Design: A total of 120 patients with symptomatic knee OA were randomized into two groups receiving either 800 mg CS or placebo (PBO) per day for two periods of 3 months during 1 year. Primary efficacy outcome was Lequesne's algo-functional index (AFI); secondary outcome parameters included VAS, walking time, global judgment, and paracetamol consumption. Radiological progression was assessed by automatic measurement of medial femoro-tibial joint space width on weight-bearing X-rays of both knees. Clinical and biological tolerability was assessed. Results: One hundred and ten of 120 patients were included in the ITT analysis. AFI decreased significantly by 36% in the CS group after 1 year as compared to 23% in the PBO group. Similar results were found for the secondary outcomes parameters. Radiological progression at month 12 showed significantly decreased joint space width in the PBO group with no change in the CS group. Tolerability was good with only minor adverse events identically observed in both groups. Conclusion: This study provides evidences that oral CS decreased pain and improved knee function. The 3-month intermittent administration of 800 mg/day of oral CS twice a year does support the prolonged effect known with symptom-modifying agents for OA. The inhibitory effect of CS on the radiological progression of the medial femoro-tibial joint space narrowing could suggest further evidence of its structure-modifying properties in knee OA.
