A total of 96 subjects with osteoarthritis were enrolled and randomized to either placebo (n = 38) or HLM treatment group (n = 38). The HLM group re- ceived a combination of Uncaria tomentosa (300 mg), Boswellia serrata (200 mg), Lepidium meyenii (1000 mg) and L-Leucine (700 mg) given as 3 capsules once a day. The placebo group received matching capsules with carboxymethylcellulose. The treatment period was 8 weeks, with assessments made at days 7, 14, 28 and 56. The primary outcome was reduction in total WOMAC score. VAS pain, tolerability, investigator assessments, use of rescue medication (acetominophen), and safety assessments of vital signs and laboratory assessments were included. Subject randomization was effective for age, gender and disease severity. In the placebo group 32/38 subjects completed the trial and for HLM 35/38. WOMAC scores (pain, stiffness, physical performance and total) steadily declined over the course of the 8 week study in both groups, but the magnitude was significantly greater for HLM (P < 0.05). Total WOMAC was reduced 46.5% for HLM and 25.4 % for placebo. VAS pain was reduced 21.8% in the placebo group (p < 0.002) but the changes were significantly greater (37.8% p < 0.03) with HLM treatment. Investigator’s global assessment rating of good-excellent was 24/35 (69%) for HLM and 14/32 (44%) for placebo (P = 0.05). Rescue medication consumption and tolerability were comparable for HLM and placebo. No safety issues were evident with either group. As expected a placebo effect was observed, nevertheless HLM was clearly more effective in relieving the symptoms of osteoarthritis. This HLM represents a safe and effective new approach to the management of osteoarthritis symptoms.展开更多
