methods using adipose tissue-derived cell suspensions comprising
adipocytes' for the use of the AdiCell™ method on mammals for the
treatment of certain inflammatory diseases and pain related to those
conditions ( http://www.wipo.int/portal/index.html.en , Patent Search,
2011). The WIPO application was approved in February 2010. The
application is currently under consideration by the Australian Patent
Office and once granted will be valid until August 2029 ( http://www.
ipaustralia.gov.au ). The documentation available on the AusPat
database (an online searchable database of Australian patents hosted
by IP Australia: http://www.ipaustralia.gov.au/auspat/index.htm )
explains in detail the diseases, animals and applications covered in
the application. The patent application is also under consideration
by the European Patent Office.
Regeneus potentially has some competition in the human market,
however. The Australian New Zealand Clinical Trials Registry
(ANZCTR) ( http://www.anzctr.org.au ), a voluntary clinical trials
database maintained by the University of Sydney, has another
osteoarthritis-related adipose-derived stem cell trial listed for patients
with knee osteoarthritis. In this Phase II/III double blind randomized
controlled trial, patients will receive three injections two months
apart and will be followed up for 12 months to test their improved
joint function, reduction of pain and cartilage repair. The control
group will receive an alternative but established treatment for the
same condition. This trial is sponsored by the Australian Catholic
University, in conjunction with a Melbourne-based sports medicine
clinic that will facilitate patient recruitment of up to 60 individuals.
Although the trial has not yet (at the time of writing) received
institutional ethics approval ( http://www.anzct.org.au ), an adipose-
derived stem cell treatment is currently being offered through the
Melbourne sports medicine clinic. The Melbourne group's treatment
regime involves mixing a patient's own platelet-rich plasma with the
isolated stem cells from emulsified fat obtained from the patient
under an LED light and then injected into the site of damage in the
joint (Lakeside Sports Medicine Clinic, http://www.lakesidesmc.
com.au , 2011). On their website they claim to have successfully
treated one patient so far. Their patient information statement
estimates that the cost of treatment is around AU$3000, and they
