PAVmed Collaborates with Canon on DisappEAR™ Pediatric Ear Tubes


Executed LOI with Canon Virginia, Inc. to develop and implement commercial grade processes to manufacture molded resorbable pediatric ear tubes from aqueous silk fibroin

NEW YORK, June 03, 2020 (GLOBE NEWSWIRE) -- PAVmed Inc. (Nasdaq: PAVM, PAVMZ) (the “Company” or “PAVmed”), a highly differentiated, multiproduct medical device company, today announced the Company and global manufacturer Canon Inc.’s United States manufacturing and technology center, Canon Virginia, Inc. (“Canon Virginia”), have executed a letter of intent (the “LOI”) to consummate a series of agreements to develop and utilize Canon Virginia’s commercial grade and scalable aqueous silk fibroin molding process to manufacture PAVmed’s DisappEAR molded pediatric ear tubes for commercialization.

“We are very proud to partner with such a highly-respected leading global manufacturer as Canon to develop and commercialize our DisappEAR resorbable pediatric ear tubes,” said Lishan Aklog, M.D., PAVmed’s Chairman and Chief Executive Officer. “Canon’s extensive experience and expertise in innovative and efficient production methods and its vast state-of-the-art facilities in Newport News, Virginia, make it the ideal partner to develop this groundbreaking technology for the one million children who currently undergo ear tube placement each year.”

Under terms outlined in the LOI, PAVmed and Canon Virginia propose to enter into two sequential agreements covering a five-phase project culminating in the commercialization of PAVmed’s DisappEAR molded pediatric ear tubes.

“Canon operates under the philosophy of Kyosei, which means ‘living and working together for the common good’,” said Toru Nishizawa, President and Chief Executive Officer of Canon Virginia, Inc. “We look forward to working together with the PAVmed team to improve the care of patients by offering our world class manufacturing and process expertise to the development and commercialization of silk-based resorbable ear tubes.”

Each year, up to one million children with persistent ear infections (otitis media) or middle ear fluid collections (effusions) undergo placement of metal, plastic or latex bilateral ear tubes to drain the middle ear. This procedure, formally known as bilateral tympanostomy, is the most common pediatric surgical procedure in the United States. Up to 50% of patients require repeat surgery under general anesthesia to remove the tubes once they are no longer needed or if they become dislodged and do not fall out of the ear canal on their own.

PAVmed licensed the technology underlying its DisappEAR resorbable ear tube from Tufts University on behalf of itself and other leading academic institutions including, two Harvard Medical School teaching hospitals – Massachusetts Eye and Ear Infirmary and Massachusetts General Hospital – as well as, Massachusetts Institute of Technology and Eidgenössisches Technishe Hochschule Zürich. The tubes are manufactured from a proprietary aqueous silk technology which is designed to slowly be reabsorbed over the intended course of treatment.

PAVmed believes that DisappEAR has the potential to revolutionize the care of children with complex or recurrent otitis media by avoiding a second procedure and eliminating the need for a seven to 10-day post-operative ear drop regimen, which is challenging for parents to administer. It also expects fewer complications, including fewer ear tubes remaining in the ear canals for years after becoming dislodged, a situation which may lead to pain, bleeding or an obstructed view of the ear drum required to identify recurrent middle ear infection.

PAVmed has completed extensive animal testing of DisappEAR ear tubes machined from blocks of this proprietary silk technology. In a six-month study performed by Christopher J. Hartnick, M.D., Professor of Otolaryngology at Harvard Medical School and Chief of Pediatric Otolaryngology at Massachusetts Eye and Ear Infirmary and Massachusetts General Hospital, the DisappEAR tubes remained widely patent throughout the duration of the study, retaining their implant position with good healing of the ear drum. Perhaps more impressively, the tubes showed unexpected surfactant properties which appear to provide several unique benefits over traditional plastic tubes, including enhanced drainage of fluid from the middle ear, potential intrinsic antimicrobial properties and a surprising absence of otorrhea – a difficult to manage condition where pus and fluid drains out of the middle ear and into the ear canal and typically occurs in at least 25-30% of recipients of traditional plastic tubes, despite administration of antibiotic ear drops.

Recent advances in molding processes for aqueous silk fibroin has led PAVmed to transition DisappEAR’s design from machining blocks of silk to injection molding, a much less costly and efficient commercial manufacturing process, especially at scale. PAVmed sought to partner with Canon Virginia because the Company believed it to be the most technologically capable and respected manufacturer developing a scalable commercial grade process to produce aqueous silk fibroin for human clinical applications.
