Flexiseq(R): Study shows novel, drug-free gel to be as effective as a prescription drug at relieving osteoarthritis pain

>PRWEB.COM Newswire

London, England (PRWEB UK) 10 April 2013

Key trial data supporting Pro Bono Bio’s (“PBB”) drug-free osteoarthritis (OA) treatment Flexiseq, have been published today in "Rheumatology", the official journal of the "British Society for Rheumatology". The event is the latest high profile publication and achievement for the product after winning a German pharmacy award for innovation in January 2013.

The publication reports that Flexiseq (TDT 064)* was equivalent to the oral non-steroidal anti-inflammatory drug (NSAID) celecoxib and was better tolerated by patients. The findings offer hope to osteoarthritis patients, particularly those who are at risk from the gastrointestinal and cardiovascular side effects associated with commonly prescribed pain killers (NSAIDs) such as celecoxib and diclofenac.

Professor Conaghan, lead author of the international study said: “Most people with osteoarthritis live with chronic pain that interferes with their daily activities. Many can’t take or can’t tolerate current oral analgesics because of side effects. There is therefore a huge unmet need for effective and safe analgesics for osteoarthritis. The new study is interesting because it suggests that a novel topical therapy, that doesn't include a topical anti-inflammatory drug, may help osteoarthritis pain (and mobility).”

At the end of the 12 week trial in which Flexiseq (TDT 064) was the drug-free control arm, the 238 patients who applied Flexiseq (TDT 064) twice a day experienced a 39.8% average reduction in pain, equivalent to the comparator – the regularly prescribed drug used for OA pain, celecoxib. Similar reductions were reported for joint function and stiffness. As would be expected for a non-drug treatment, Flexiseq (TDT 064) was well tolerated with the majority of adverse events being mild to moderate local skin irritations. The majority of adverse events from those patients given celecoxib were gastrointestinal disorders, as would be expected from an oral NSAID.

Professor Bolten, a co-author of the study, highlighted the relevance of its findings for the population of cardiovascular patients also suffering from osteoarthritis and at risk from NSAID related side effects: "For topical TDT 064 (Flexiseq), the study showed the same pain and stiffness reducing qualities as oral celecoxib. As TDT 064 (Flexiseq) does not contain any NSAID (or other pharmaceutical ingredient), side effects are very rare and it does not interact with other drugs. Therefore the many elderly osteoarthritis patients with cardiovascular problems, in which NSAIDs are contraindicated, can be treated at low risk.”

Awarded ‘Innovation of 2013’ in Germany by the Federal Association of German Pharmacists, Flexiseq is engineered to treat osteoarthritis via a cutting edge, physical mode of action. The product employs Sequessome Technology(R) rather than an active pharmaceutical ingredient to provide equivalent pain relief and improved joint function to a prescribed pain killer (NSAID) but with a more favourable safety profile, as shown in the "Rheumatology" publication.

Michael Earl, a director of Pro Bono Bio said: “Sufferers of osteoarthritis are not presented with a lot of different options when it comes to treatments and it is, sadly, inevitable that a subset of these patients will develop unpleasant and potentially dangerous side effects due to their treatment. Flexiseq offers some hope to this “at risk” population as a topical, drug-free intervention with clinically meaningful efficacy, as reported in "Rheumatology". We are delighted that this part of Flexiseq’s clinical data has been brought to a wider forum”.

Flexiseq is already available in the German and Malaysian markets (from pharmacies and clinics) and is a CE marked, class IIa medical device. PBB intends to make the product available to new markets later this year, continuing its run of success.

About Sequessome Technology

Sequessome Technology utilises nanostructures called Sequessome(TM) vesicles that cross the skin barrier after the gel's topical application and migrate through various tissues to reach the target joint. Once inside the joint, Sequessome vesicles accumulate on the damaged cartilage forming a lubricating layer. This targeted, physical mode of action crucially means there are no drug-to-drug interactions with Flexiseq as it is not itself a drug and, as a result, it can be used by patients who may be taking a variety of medications for other diseases, without increasing their drug burden. Flexiseq is also a welcome option for patients considered ‘at risk’ from the common side effects associated with NSAIDs for example, those with such conditions as high blood pressure and/or gastric disorders.

About Pro Bono Bio

PBB has ambitious growth targets that will allow it to support a unique humanitarian mission. In 2012 it supported elderly pilgrims on the Hajj to Mecca, alleviating the joint pain caused by long periods of walking and kneeling.

Pro Bono Bio is an innovative pharmaceutical and nano medical device company launched in 2011. Pro Bono Bio launched Flexiseq in Europe in the first half of 2012 and plans to launch two further new products for the treatment of inflammatory skin disorders in early 2013. These new products, Rossoseq(R) and Exoseq(TM), are based on Sequessome Technology, the same technology that powers Flexiseq.

  • On account of Flexiseq not containing an active pharmaceutical ingredient and also being a medical device with a physical mode action, the product has no generic identifier. Therefore all references to Flexiseq in published scientific literature such as the "Rheumatology" article will be as TDT 064, the product’s study code. Therefore in order to locate Flexiseq articles in literature databases, suggested search terms are as follows: “TDT 064” and/or “Sequessome”.
