Perfect patches for patients

3 November 2015

Summary

• Medherant is developing a new class of drug delivery

patch that can provide a variety of USPs to products

• Formed as a spin-out from the world leading polymer

chemistry group at University of Warwick

• Exclusive, worldwide technology license from Bostik
• Medherant patches have broad applications and offer

multiple benefits

• Wide range of chemical compatibility
• High loading of both high and low-potency drugs
• Good adhesion and clean removal
• Clear and flexible – attractive and easy to wear
• Simple, low-cost manufacture
• We are seeking co-development partners and investors

to support development of our own products

Patches

• Benefits of patches
• Dose control
• Avoidance of GI damage (whether to patient or drug)
• Convenience
• Steady release
• Current limitations
• Available for very few drugs
• Difficult to formulate for low-potency drugs
• Poor patient experience in some cases
• Simple matrix patches limited by low loading, loss of adhesion
• Partially overcome by reservoir type patches, but these are

cumbersome and complex to manufacture

Medherant patches

• Single layer, drug in adhesive matrix
• Simple and cheap to manufacture
• Higher loadings than current patches or gels
• Compatible with a wide range of drug types
• High range of MWts and hydrophobicities
• Steady rate of drug release
• Can tailor rate with addition of excipients
• Excellent adhesion, even at high drug loading
• Clear, thin, flexible and attractive
• No residues after removal

Drug compatibility

Prolonged high dose rate for both low potency (l) and high potency drugs (r)

Drug release: Medherant vs Market leaders

Enhanced long-term drug delivery

Adhesion

• Strong adhesion even at high drug

loadings

• Combined with flexibility gives good

adhesion to joints, curved surfaces

• Easily removable
• No tearing
• No residues

Peel adhesion test

Products available for licensing

Ibuprofen patch

• First ever Ibuprofen patch
• High drug loading (10-30% w/v)
• Tailored delivery profile
• 1hr – 12hr
• Colourless and transparent
• Highly adhesive yet easy to

remove

Methyl Salicylate patch

• High drug loading (10-30% w/v)
• Long lasting
• Adhesion not hampered by

high drug load

• Enhanced comfort
• Choice of backing materials

Conclusion

• Medherant has an excellent platform technology for the

development of a wide range of drug delivery patch products with significant USP’s

• We are seeking:
• Partners for the development of our Methyl Salicylate patch

and for the first ever Ibuprofen patch

• Investors for our Series A round in Spring 2016
• We offer:
• Rapid, low-cost feasibility studies to explore NCE’s that may

benefit from transdermal delivery due to problems with GI toxicity or first pass metabolism or for life cycle management
