Phosphagenics Delivers Further Positive Oxycodone Patch Trial Results
15 February 2012.
Australian drug delivery technology company Phosphagenics Limited (ASX: POH, OTCQX: PPGNY) today announced positive results from the clinical trial using its new TPM/oxycodone patch.
The patch developed for commercial application in collaboration with global partner 3M, was trialed on 45 subjects at the Royal Adelaide Hospital’s CMAX facility.
The trial was designed to characterise and assess the oxycodone delivery profile from a single 3-day application of the 3M developed TPM/oxycodone patch system.
Results have demonstrated that the new patch delivered 4.5 times more oxycodone over 72 hours into the blood compared to the original prototype developed by Phosphagenics more than a year ago.
Further, the patch was half the size of the original prototype and had the characteristics of a commercial patch.
Phosphagenics’ CEO, Dr Esra Ogru said: “The trial results confirm we have a viable product. While minor improvements will be undertaken to further optimise the patch, we will address these comfortably in the knowledge that we have produced a commercial patch with potential global impact.”
Dr Ogru said the patch exhibited superior delivery of oxycodone compared to the original prototype.
“The rate of oxycodone delivery from this new patch was exceptional and has the potential to provide longer-term pain relief from a single patch”, she said.
“Clinically the new patch is of significant benefit from a safety and anti-abuse perspective in comparison to current oral dosage forms. Our patch with the sustained delivery profile will minimise the potential for overdose, reduce the rate at which drug tolerance develops and improve patient compliance.
“We believe that this result will be looked upon positively by both clinicians and the regulatory agencies.”
Phosphagenics’ top-level regulatory advisors have responded favourably to the trial results. Our senior advisor, Lee S Simon MD, a former Division Director of Analgesic, Anti-inflammatory and Ophthalmologic Drug Products (DAAODP) at the FDA commented: “The delivery profile from this patch is extremely interesting and points to the need to engage with the FDA as soon as is practically possible. These results indicate that Phosphagenics is well on the way to creating a unique product.”
Dr Ogru said minor formulation changes will be undertaken to improve the final commercial product.
“Phosphagenics has chosen to address these changes now before progressing into the multiple dosing component of the clinical program, which will lead into the fully funded Phase 3 program expected to start later this year”, she said.
Prior to starting the Phase 3 program Phosphagenics will meet with the US FDA to get clinical study sign-off.
Based on a previously announced Physician’s Survey, projected demand for the TPM/oxycodone patch is expected to exceed $1 billion per annum. The current global oxycodone market exceeds $3 billion per annum.
