LEO Pharma A/S and LTS Lohmann Therapie-Systeme AG initiate first-ever clinical trial of microarray patches for psoriasis treatment

A microarray patch (also known as a microneedle patch) is a polymeric, microscopic array which delivers encapsulated drugs by perforating the outer stratum corneum with numerous microneedles. The needles are biodegradable and will dissolve as they release the drug in the skin.

This is the first time that microarray patch technology is applied to psoriasis treatment, representing a novel dosage form with several potential benefits for patients: The microarray patch enables slow release of the drug (betamethasone and calcipotriol), which means that treatment frequency can potentially be reduced from one or more times daily to once weekly. Furthermore the patch may reduce or potentially eliminate the need for application of topicals such as ointments. Application of the patch is precise due to the small size of the micro needles ensuring that only affected skin is treated.

The micro array patch for psoriasis treatment has been developed jointly between LEO Pharma and LTS’ laboratories and has Good Manufacturing Practice (GMP) status. The project is the first result of a partnership agreement which the two companies entered in 2016.

“After a successful preclinical development in the last two years, initiating a human study in corporation with LEO Pharma is the next major milestone. Our Micro Array Patch (MAP) platform allows the active ingredient to be released directly into the skin MAP innovation is driven by a productive and constructive cooperation using core competences of LEO Pharma and LTS,” said Stefan Henke, Head of LTS‘s Innovative Injection Systems Unit.

“Our alliance with LTS is a great example of LEO Pharma’s innovative approach to psoriasis treatment and how we collaborate to improve and extend what’s possible for the benefit of patients. The microarray patch represents a new treatment method, which we believe has the potential to improve both treatment compliance and convenience – thus helping even more patients achieve healthy skin,” said Kim Kjøller, Executive Vice President, LEO Pharma Research & Development.
