Partnering opportunity

Nanocapsule compositions for the controlled released of agents of therapeutic interest


A Spanish research centre, in collaboration with a Spanish university, works on biomaterials. They have developed a nanocapsule compositions capable of releasing agents of therapeutic interest with a controlled kinetic and a prolonged and sustainable effect over time; reducing the overall administration required. They are looking for license agreement.

Partner sought

They are looking for a company working on pharmaceutical or biotechnology sector. They should have the capacity to develop nanocapsule. The roll will be to adapt the nanocapsules to their needs and bring it to market, The Spanish groups are looking for license agreement, but if needed they could cooperate with the company in any further development.


Fibrosis is a common lesion in different pathological conditions and it is defined by the excessive accumulation of collagen and other extracellular matrix proteins in the connective tissue of different organs where it causes organ dysfunction. Collagen corresponds around of 30% of all proteins in humans, and is the major extracellular protein of different organs such as the skin, cartilage, bones, teeth and cornea. To prevent this collagen accumulation, proteases are used. Proteases target many substrates, thus inflicting changes in distinct biological processes correlated with fibrosis. At present, there is still a need to provide protease carriers or vehicles capable of achieving a constant and continuous release of the proteases encapsulated within at therapeutic doses during a sufficient period of time for the treatment of diseases which require a sustained protease administration during treatment periods greater than one week. A Spanish research team from a of a university hospital and a Spanish university are working on biomedical research in biomaterials and biomedicine. The hospital team works on the rheumatology and dermatology department and the university professor on smart biomaterials for pharmaceutical used. They have developed a nanocapsule compositions capable of releasing agents. The agents, proteases of therapeutic interest, can be released with a controlled kinetic and a prolonged and sustainable effect over time. The controlled and sustained released solves the above mentioned problems for treatments that last more than one week. It provides sustained release polymeric nanocapsules capable of releasing proteases such as collagenase with a controlled kinetic and a prolonged and sustainable effect over time. The team is looking for license agreement. They are looking for pharmaceutical or biotechnology companies working on biomolecules, nanocapsules or nanoparticules, to license the patent. It will be desired if they have interest in fibrosis treatment.

Advantages and innovations

This novel nanocapsule composition is adaptable to encapsulate and effectively deliver agents of therapeutic interest reducing the overall administration required. These capsules provide a sustained release of the housed enzyme thus providing a therapeutic improvement in comparison to current therapies thus decreasing the need for repeated injections or high collagenase doses.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
