In February 2019, the UK Medicines and Healthcare products Regulatory Agency (MHRA) responded to Thornton & Ross’s marketing authorisation application filed in July 2018, raising a number of questions requiring additional laboratory work specifically around the permeation characteristics of TPR100 to be conducted. The additional lab work has been completed indicating that absorption of TPR100 is significantly superior to the market leader. These results were discussed with MHRA in a Scientific Advice meeting and it was determined that as there was non-equivalency a clinical study was required. MHRA suggested that the clinical study could be used to support superiority claims for the formulation. FUM are determining how this study could be funded and used to support the product in markets around the world including the US where Voltaren (GSK) have recently achieved OTC designation.
Our transdermal technology DermaSys® is tailored for each product to suit the specific therapeutic indication and desired speed of onset and duration of action offering improvements over existing products creating novel indications with compelling commercial potential. This means that our products are highly differentiated in their markets whilst avoiding the risks normally associated with the development of new molecules.
The rapid skin permeation rate offered by our transdermal delivery system, DermaSys®, is ideally suited for targeted topical pain relief. Rapid, targeted and effective skin permeation offers potential benefits in pain management including: improved onset of action, duration and degree of pain relief.
TPR100 does not require a combination of volatile solvent components to stimulate nerve sensors. It is designed to provide a sustained mode of action suitable for the treatment of pain and is formulated with this objective in mind.
TPR100's current patent protection runs until February 2028 in the USA and Europe.
