Portaero, Inc. Company Profile

Founded in 2007, Portaero is a private, California-based, clinical stage medical device company. Over the past 6 years, Portaero has raised approximately $20mm in equity and debt from the leading venture capital firms Versant, Aberdare, and Novartis Ventures.

Portaero is a leader in developing innovative, therapeutic devices to treat advanced, homogeneous emphysema. It is the only therapy currently in patients whose primary indication for the FDA pivotal trial will be homogeneous emphysema.

Portaero’s therapy targets patients whose lungs are hyperinflated due to emphysematous destruction and dynamic airway collapse. The Portaero Access Tube System creates a transthoracic pneumostoma which is subsequently managed by the patient with the Portaero Daily Disposable Tube.  When patent, the pneumostoma reduces the amount of trapped gas and the pressure in the diffusely destroyed lung, thus restoring the productivity of the native airways, improving overall lung function, and increasing patient quality of life.  Early experience also suggests pneumostoma patients experience a lower rate of exacerbations.  Exacerbations make these patients among the most expensive in the health care system.

Portaero believes its assets are attractive for a number of reasons:

·     Portaero is the only device in development which has generated data in homogeneous patients that warrants inclusion of those patients in a US PMA trial.

·     6+ years of clinical experience supports the safety and the efficacy of the therapy.

·     Current patients continue to manage their pneumostomas from 1+ years to 6.5 years.

·     Portaero Intellectual Property, comprising 25 issued US patents, 15 pending US patent applications, 10 issued international patents and 10 international pending patent applications, is the earliest and most comprehensive portfolio for    transthoracic bypass. Some of Portaero patents also apply to using the Portaero port for improving drug delivery to the lung.

·     The Portaero Access Tube System is placed by a thoracic surgeon via a mini-thoracotomy.  The 45 minute procedure requires no special skills and has been completed under both local and general anesthesia.

·     The Portaero Daily Disposable Tube has successfully been managed by a wide variety of patients.

·     The Portaero Reopening Device is designed to be used by an Interventional Bronchoscopist or surgeon.  It should be a simple, safe, outpatient procedure that can be quickly done at the end of the bronch list.

·     The Portaero therapy is very accessible to health care capabilities worldwide.

·     The Portaero system fits well with the direction of reimbursement systems that prefer to pay for desired outcomes.  The bulk of the economics is in the disposable which is only used if the patient is receiving benefit.

·     A leading clinician experienced with Portaero and other emphysema therapies believes Portaero patients have a lower exacerbation rate than untreated patients.

·     The Portaero therapy is reversible.  No patient has been worse off for having tried the Portaero treatment.

·     Preliminary BODE data suggest the potential to increase life expectancy with the Portaero therapy.

·     In the long term, the patents allow for development of a percutaneous procedure for interventionalists.

Impact of Technology on the Market

Patients with homogeneous emphysema represent a large, growing market with an unmet clinical need. Accessing Portaero’s intellectual property is critical for any successful endeavor into this very attractive market. Portaero’s therapy is complimentary to other therapies addressing heterogeneous disease (e.g., valves, coils, steam, glue) and could be sold by the same sales force.

Intellectual Property Summary

Portaero has a comprehensive intellectual property portfolio consisting of 35 issued patents: 25 are issued for the US and 10 are issued for International.  Portaero has 25 pending applications: 15 pending for the U.S. and 10 pending for International.  Description of the portfolio can be found in the Appendix B.  The portfolio represents a broad array of strategic variables including:

Methods and devices used by patient to maintain and protect the pneumostoma
Methods and devices for pneumostomy procedures for creating a pneumostoma
Methods and devices for assessment, maintenance, and treatment of a pneumostoma
Portaero’s Assets

Portaero has developed a portfolio of assets critical to the treatment of emphysema via a pneumostoma. These assets fall into a variety of categories, including:

·     Patents and Patent Applications
·     Patient Data Set for Treating Homogeneous Emphysema from 2 different non-randomized clinical studies
·     Design and manufacturing documentation for surgical and patient care products
The assets of Portaero will be sold in whole or in part (collectively, the “Portaero Assets”). The sale of these assets is being conducted with the cooperation of Portaero. Portaero will be available to assist purchasers with due diligence and a prompt, efficient transition to new ownership. Notwithstanding the foregoing, Portaero should not be contacted directly without the prior consent of Gerbsman Partners.
