Acrux patent portfolio advances in USA
- New patent granted in USA for MDTS® drug delivery system
- Protection against copies of Acrux unique transdermal sprays extended out to 2022
- Nine patents now granted in USA
Acrux has received notification of the grant of a US patent (number 6,978,945), which provides robust protection for its Metered Dose Transdermal Spray (MDTS®)applicator for delivery of drugs. The applicator is currently used in the three women's health products that Acrux has under clinical development – the contraceptive spray Nestorone® MDTS®, Testosterone MDTS® to treat decreased libido and Evamist
Acrux CEO Igor Gonda commented "This new patent provides very broad protection for the familiar part of our products that the patient sees and uses. It means that copies of our unique transdermal spray devices that provide a precise and convenient means of drug delivery are now kept out of the market until 2022 at the earliest".
In addition, Acrux has been granted another US patent (number 6,998,138), expiring in 2017, which provides an additional layer of patent protection for delivery of anti-alopecia (baldness) drugs using Acrux's fast drying skin delivery technology. Alopecia treatments are a part of Acrux's valuable portfolio of dermatology products.
