Study hypothesis
Boswellia serrata extract have been proven to be effective against inflammatory disorders in clinical trials, but no comparative clinical investigation has been carried out to demonstrate the efficacy and underlying mechanistic pathways involved therein. Furthermore, a broad spectrum of studies have evidenced that non-steroidal anti-inflammatory drugs (NSAIDs) induce painful gastrointestinal irritation as well as bleeding. No such adverse effects have been reported for natural Boswellia products.
In recent past, we have developed and proved clinical efficacy of a novel Boswellia serrata extract (5-Loxin®) enriched with 30% acetyl-11-keto-beta boswellic acid (AKBA) (Pending US patent [ref: 2004/0073060A1], Indian patent [ref: 205269], Australian patent [2002242934]). In a published clinical study (http://www.ncbi.nlm.nih.gov/pubmed/18667054; registered with ISRCTN05212803), we have shown that oral administration of 5-Loxin® conferred significant improvement in clinical signs and symptoms of patients with osteoarthristis (OA) of knee. This study also suggests that 5-Loxin® can normalise the elevated Matrix metalloproteinase-3 enzyme in synovial fluid which helps to reduce the cartilage degradation in OA.
However, till date no clinical study has been reported the comparative efficacy of 5-Loxin® and Boswellia serrata extract in OA. Therefore, in the present clinical study we designed to assess comparative efficacy of 5-Loxin® with Boswellia serrata extract (BE) against OA of knee.
