Study ID: 957
Research Type: Validity
Expiration Date: 2012-04-05



References of interest: Conference Notes and Non-patent literature

No further patents are to be submitted


This Study relates to a method for treating a knee joint of a subject suffering from osteoarthritis with an injectable hyaluronic acid viscosupplement. 

The viscosupplement is administered intra-articularly to the knee joint in a single dose (either as a single injection or as a series of multiple injections within a 24-hour period) and comprises a hyaluronan (HA) based viscosupplement that does not contain additional active components.  The total dosage is between 24 mg and 100 mg.

References of interest may describe the half-life of the HA product, and references of particular interest describe HA products for which the half-life measurement was based on data points taken beyond 28 days post-injection and/or taken throughout the period of efficacy

References of particular interest will disclose a method of administering 2 or 3 intra-articular injections of Synvisc® (Hylan GF20) or Jonexa (Hylastan SGL80) (viscosupplement) at one time.

References disclosing a method of administering 2 or 3 intra-articular injections of the following viscosupplement products at one time are also of interest:

•  Artz® or Supartz® or Artzal

•  Hyalgan® or Hyalart

•  Euflexxa®

•  Orthovisc® or Monovisc®

•  Neovisc

•  Ostenil

•  Suplasyn

•  BioHy

•  Coxarthrum

•  HyalOne

•  Synocrom Forte

•  Maxiostenil

•  SportVis

•  Durolane

•  Hyal 50%


Some possible Organizations and Groups of particular interest:
1) Orthopedic Conferences/Organizations
2) Physical Medicine and Rehabilitation Organizations and Conferences. The American Academy of Physical Medicine and Rehabilitation would be a good example. Doctors in this area of practice are known as a Physiatrist if this helps.
3) Internal Medicine Societies and Conferences. Internal Medicine is a broad topic so please focus references on the areas outline in the Study.
4) Pain Specialist Organizations
5) Pain Clinics – These clinics often had days where patents could just come to get their injections and they believe this maybe a place where this method of administration was use.
