Hyaluronan Product Development & Regulatory Support

Product Development

With years of experience in Hyaluronan product development, our team can support in getting from the very initial stages of product concept through to product launch.

We have extensive experience working with medical device and pharmaceutical clients developing new products and/or the optimisation of existing products in the areas of dermo cosmetics (topical and injectable), dermal fillers, mesotherapy, wound care, ophthalmology, orthopaedics and oncological applications.

We can also support in the area of drug delivery and controlled release.

Regulatory Support

With an ever changing regulatory environment, we can help in developing a regulatory plan to meet the needs of any Hyaluronan based medical device or drug product.

We can support in the following areas:

  • Development of a Regulatory Plan
  • Development of a Quality Management System (QMS)
  • Choice and dialogue with an appropriate authority/notified body
  • Understanding and compliance with the Medical Device Regulation (MDR) and/or the Medical Device Directive (MDD)
  • Preparation and submission of relevant documents
  • CE marking and registration

Hyamedix can also assist in any other aspect of developing new products in regards to production and lab set up, scale up and any other production related demands.

Intraarticular steroid injection has been the mainstay of short-term treatment of knee osteoarthritis (OA) pain. However, the duration of therapeutic effect from a single injection is not as long as desired. In this study we use a viscous formulation of triamcinolone acetate (TCA) in hyaluronic acid to prolong the anti-allodynia effect of that steroid. OA was induced in mice by a partial medial meniscectomy. Over time the animals' developed a mechanical allodynia in the injected leg. Mice were then given a single intraarticular injection of TCA in a short-acting DMSO formulation, or a standard commercial suspension, or the drug formulated in 5% hyaluronic acid for slow-release. Control injections in OA mice were PBS or 5% hyaluronic acid vehicle. Mechanical allodynia was then monitored over the therapeutic period. Organotypic spinal cord slices and DRG culture were performed to assess whether TCA attenuates expressions of pain mediators induced by interleukin 1β. TCA 40μg in a fast-releasing DMSO formulation produced relief from mechanical allodynia for a few days compared to PBS control injections (P=0.007). Similarly, the commercial suspension of TCA 40μg also produced relief from mechanical allodynia for a few days compared to PBS control injections (P=0.001). However, TCA 100μg in 5% hyaluronic acid produced relief from mechanical allodynia for at least 28days compared to PBS control or 5% hyaluronic acid vehicle injections (P=0.0005). Furthermore, TCA significantly suppressed expression of pain mediators induced by interleukin 1β in spinal cord and DRG organotypic culture. Intraarticular TCA in a sustained release formulation of viscous 5% hyaluronic acid will produce a long-term attenuation of mechanical allodynia in the OA knees of mice.
