Lombard Medical Technologies Wins U.S. Nod for Aortic Stent
Published: Feb 15, 2013
The U.S. approval for Aorfix™ includes a label indication for the treatment of patients with angulations at the neck of the aneurysm from 0 to 90 degrees. Aorfix™ is now the only endovascular stent graft licensed in the U.S. for use in more challenging cases with neck angulations greater than 60 degrees. Independent market research suggests that the U.S. market for the repair of AAAs is worth over $600 million per annum1, is forecast to grow at approximately 8%1 per annum, and that up to 30% of all patients have some tortuosity either at the neck of the aneurysm or in the iliac arteries2. It is to this segment of patients that Aorfix™ is targeted with its uniquely flexible design. In Europe Aorfix™ is already licensed to treat neck angulations of up to 90 degrees.
The PYTHAGORAS trial of Aorfix™ is the largest prospective controlled study, to date, of stent grafting in patients with highly angled aortas. 218 patients at risk of aneurysm rupture were recruited in the trial and included 151 patients with neck angles greater than 60 degrees and 67 patients with neck angles less than 60 degrees. No aneurysms expanded in patients with neck angles less than 60 degrees and just 1.8% expanded in the patients with high neck angles, comparing favourably with the results of other devices in normal, less tortuous anatomy.
The approval of Aorfix™ triggers receipt of the c. £14.1m Second Tranche of the two tranche placing and subscription announced by the Company on 20 April 2011 (the “May 2011 Fundraising”). Funds from the Second Tranche will be used to launch AorfixTM in the U.S. through the Company’s own direct sales force. In addition to building the U.S. sales and marketing infrastructure, funds from the Second Tranche will also be used to expand production capacity to meet anticipated demand for the AorfixTM stent graft, complete the planned extension of stent graft sizes and develop the next generation, lower profile delivery device.
Funds from the Second Tranche will also be used to redeem the full amount of the £3m Convertible Loan Notes issued to Invesco Asset Management Limited ("Invesco") to the extent that Invesco has not already converted, or indicated its willingness to convert, the Convertible Loan Notes. Additional funding will subsequently be sought to allow the Company to achieve its longer-term goals in the U.S.
U.S. approval of Aorfix™ also triggers the Company’s ability to draw down $2.5m from the $5.0m loan facility granted by its exclusive distribution partner in Japan, Medico's Hirata Inc. Medico's Hirata is a leading supplier and developer of medical device products in Japan, with the sales infrastructure to maximise the potential of Aorfix™ in this important market. Lombard Medical continues to work with its partner to achieve Aorfix™ approval in Japan, which it anticipates will be in 2014.
In May 2012 the Company announced a strategic partnership with Machine Solutions Inc. (MSI), a global supplier of process and testing solutions for the medical device industry. This partnership formed part of the Company’s wider plan to develop improved manufacturing processes and efficiencies for Aorfix™. In utilising technology developed in collaboration with Machine Solutions, the Company is confident of meeting product demand and capacity requirements following the launch of Aorfix™ in the U.S.
CEO of Lombard Medical Technologies, Simon Hubbert, commented:
“FDA approval of Aorfix™ is a major milestone for the Company and sets the stage for the next chapter in the Company’s growth. I would like to thank all of our employees, investigators and clinical advisors for their support and hard work, without which development and approval of Aorfix™ would not have been possible. Aorfix™ is now the only stent graft approved in the U.S. to treat AAAs with neck angulations up to 90 degrees, a key advantage over other currently available stent grafts. We look forward to launching Aorfix™ in the U.S. through our own sales force and are confident of securing a meaningful share of this growing market.”
Dr Mark Fillinger of Dartmouth Hitchcock Medical Centre, New Hampshire (principal investigator for the Aorfix™ trial), commented:
“Having seen the benefits of using Aorfix™ in patients first hand, I am delighted such a device is now available to treat patients in the U.S. Aorfix™ allows a minimally invasive repair of complicated high-angle AAAs to be performed, addressing a clear unmet medical need. These patients would otherwise require relatively high risk and more expensive open heart surgery and many are not strong enough to undergo such a serious intervention.”

May 2011 Fundraising
In May 2011, the Company completed a two tranche fundraising, incorporating a placing, subscription and offer, of £27.2m before expenses.
