AERx Drug Delivery System

Intellectual Property


The Power Behind Effective Pulmonary Drug Delivery

Aradigm's innovative AERx pulmonary drug delivery platform demonstrated performance that is highly efficient and precise compared to other inhalation systems. The performance of the AERx platform is due to its unique fine mist aerosol generation systems combined with patented breath control technology. For each therapeutic application, the AERx platform can be customized to deliver drugs and biologics to treat lung diseases topically or to transport therapeutics through the lung and into the bloodstream.

AERx First-Generation Hand-Held Delivery Devices
AERx first-generation inhalation delivery systems are sophisticated electromechanical devices that were designed to achieve superior efficiency and precision required for applications such as Type 1 and Type 2 diabetes management with inhaled insulin, represented by the product AERx iDMS previously licensed to our partner Novo Nordisk. The first-generation devices include the two examples shown below. The first device is for diabetes management. It features dose titration capability to one unit, inhaled air temperature and flow control as well as electronic disease management capabilities. The second device has similar features to the AERx iDMS but is for pain management. Next to the device, the photograph shows the user and prescriber electronic keys to prevent misuse and abuse of controlled drug substances.

  AERx Second-Generation Delivery Device: AERx Essence®
AERx Essence is a small, palm-size all-mechanical device. The AERx Essence system offers a level of performance (efficiency and reproducibility) close to the first generation AERx system, but in a small, light and low-cost package, yet retaining the high durability of the first generation systems.

Efficient, Precise Aerosol Generation
Aradigm's AERx pulmonary drug delivery technology provides performance that is at the leading edge in terms of efficiency of delivery to the lung and reproducibility of dosing - not just in the laboratory but also as determined in many human clinical trials.

This method of delivery also often provides more rapid onset of action than pills or patches because molecules are more immediately absorbed into the bloodstream and avoid becoming compromised by gastrointestinal degradation and metabolism. In fact, several biologics that could not be delivered by oral administration have been delivered effectively using the AERx system.

Advanced Breath-Control Technology
Studies have shown that even well trained patients tend to develop improper inhalation techniques over time, resulting in less effective therapy. To ensure more consistent dosing and lasting beneficial effects, Aradigm's AERx delivery system employs powerful breath control methods and technologies to guide patients into proper breathing maneuvers. This feature can also be customized for different patient groups, such as young children or others with small lung volumes.

Additional Advantages of the AERx System
• Small hand-held devices
• Adequate dose typically in one or two breaths
• Liquid formulation - applicable to many valuable biologics and drugs
• Very short administration time (typically 1-2 breaths)
• Highly efficient, precise aerosol delivery
• Breath control to ensure reliable drug delivery to lung
• Outstanding reproducibility in humans
• Simple to use
• Dose titration capabilities
• Eliminates needle-phobia issues and potential for needle-stick injury

Promising Applications
AERx pulmonary delivery systems successfully delivered 15 different drugs and biologics in human clinical trials.

AERx Strip® Technology
The single-use nozzle contained in each disposable AERx Strip dosage form is created with a laser-machined array.  Nozzle hole exits are approximately 1 micron in diameter with a uniform shape, to provide consistent, fine-particles drug delivery.

Investor Relations


Zogenix Royalties ( from May/12/09 10-Q)

In August 2006, the Company sold all of its assets related to the Intraject needle-free injector technology platform and products, including 12 United States patents along with foreign counterparts, to Zogenix, Inc., a private company. Zogenix is responsible for further development and commercialization efforts of Intraject (now rebranded under the name DosePro tm ). The Company received a $4.0 million initial payment from Zogenix, and it will be entitled to a milestone payment upon initial commercialization, and royalty payments upon commercialization of DosePro products. In December 2007, Zogenix submitted a New Drug Application ("NDA") with the U.S. Food and Drug Administration ("FDA") for the migraine drug sumatriptan using the needle-free injector DosePro ("Sumavel tm DosePro"). The NDA was accepted for filing by the FDA in March 2008. The same month, Zogenix entered into a license agreement to grant exclusive rights in the European Union to Desitin Pharmaceuticals, GmbH to develop and commercialize Sumavel DosePro in the European Union. On October 31, 2008 Zogenix received a Complete Response Letter from the FDA on its NDA. On February 18, 2009, Zogenix disclosed that the Complete Response letter from the FDA cited the need for a single additional in vitro test to be conducted and that Zogenix recently submitted the requested information to the FDA. The FDA accepted this resubmission as a complete response, providing the new Prescription Drug User Fee Act (PDUFA) review date of July 15, 2009. Zogenix stated that it is their intention to launch Sumavel DosePro following FDA approval in the second half of 2009.


Here is the Sumavel DosePro that was developed by Aradigm and sold to Zogenix.  Zogenix has now teamed up with Japan's 2nd Largest pharma company (Astellas)  to market this product and ARDM will get Royalties from tese sales!

SUMAVEL DosePro Receives Marketing Approval in Germany and the United Kingdom

  Aradigm to Earn 3% Royalty on Net Sales 

 HAYWARD, Calif.--(BUSINESS WIRE)-- Aradigm Corporation (OTCBB:ARDM) (the "Company") today announced that Zogenix, Inc. ("Zogenix", Nasdaq:ZGNX) and Desitin Pharmaceuticals GmbH ("Desitin") were granted approval of the Marketing Authorization Application ("MAA") for SUMAVEL® DosePro™ (sumatriptan injection) needle-free delivery system for the acute treatment of migraine attacks, with or without aura, and the acute treatment of cluster headache by the Federal Institute for Drugs and Medical Devices of Germany (BrArM) and the Medicines and Healthcare products Regulatory Agency of the United Kingdom (MHRA). The approvals were received five weeks after receipt of the first European Union ("E.U.") approval for SUMAVEL DosePro in Denmark. According to Zogenix, Germany and the United Kingdom are two of the largest pharmaceutical markets in Europe. Aradigm is entitled to 3% royalty on net sales of SUMAVEL DosePro in all territories, including the US where this product is marketed by Zogenix and Astellas Pharma US, Inc.

Desitin is awaiting additional E.U. marketing authorizations and plans to launch SUMAVEL DosePro in Denmark and Germany in early 2011, and then follow with its U.K. launch. Germany is the reference member state for the SUMAVEL DosePro MAA through the E.U. Decentralized Procedure.

SUMAVEL DosePro offers fast acting, easy-to-use, needle-free subcutaneous administration of sumatriptan as a potential treatment alternative to oral and nasal triptans, and simple, convenient administration when compared to traditional, needle-based sumatriptan injection. According to Zogenix, these unique attributes may be ideally suited for challenging migraine attacks, such as morning migraines, fast onset migraines and migraines with vomiting.

In August 2006, Aradigm sold all of its assets related to the needle-free injector technology platform and products, including 12 United States patents along with foreign counterparts, to Zogenix. Aradigm is entitled to royalties from the sale of all products based on this technology platform.
