​ExSight Ventures ("EV") is pleased to announce our continued involvement and additional investment in Envision Diagnostics, Inc. ("Envision"). EV joined existing investors and new investors in Envision’s recent Series A financing. Envision is developing diagnostic devices that capture eye exams digitally. Envision's all-in-one box solution enables faster, cheaper, and more accurate readings of an eye exam. The Envision device will translate into higher quality and more efficient eye exams.
 
EV has committed additional capital in this Series A financing. Proceeds from this Series A round will fund the development of the company's Version 4 Instrument and allow Envision to execute its FDA strategy.
 
Envision recently successfully completed a clinical trial that compared Envision’s results to standard of care.
 
Envision continues to develop and iterate on its current prototype at Dr. Rahhal's clinic. Envision's data collection and standardization will revolutionize the standard of care for ophthalmology patients "by enabling consistent, reproducible testing and robust reference ranges that facilitate identification of abnormalities."
 
Envision's automation will reshape the ophthalmology by decreasing cost, increasing efficiency, improving quality, and standardizing eye exams.
 
We expect strong demand and a steep adoption curve based on clinical insights by the ExSight team and others. Funding was the single biggest challenge facing the company. With this issue now resolved, we are confident in Envision's ability to deliver on their promise of revolutionizing eye care.

ExSight Ventures (“EV”) is pleased to announce our investment DTx Pharma, Inc. (“DTx”). DTx is developing technology that will utilize RNA-based therapeutics as the preferred modality for personalized treatment across many therapeutic areas. EV joined Eli Lilly, Friedman Bioventure Fund,  Viva Biotech LTD, and Rivermount Ventures in a Series A financing of over $10M. The round also includes additional commitments from existing investors Tech Coast Angels members, and long-time partner EyeCRO toward ophthalmology focused drug development work. DTx will use these funds to build their team, advance their technology toward the clinic, and continue to build a strong intellectual property foundation.​

EV was first introduced to the DTx CEO, Dr. Arthur Suckow, nearly two years ago by Dr. Jeff Friedman. We have stayed in touch and closely followed the company’s progress. Dr. Jeff Friedman is the founder and managing partner of Friedman BioVentures. Jeff is a clinician and investor that, in addition to investing in DTx, joined the company as COO. The ExSight team also co-invested alongside Dr. Friedman in RetroSense. Dr. Friedman's joining the company is a significant endorsement of DTx’s novel, proprietary technology, and a vote of confidence in founder and CEO, Dr. Suckow. 

The biggest hurdle limiting the expansion of oligonucleotides as a therapeutic class is delivery–finding safe and effective ways to get siRNA into cells outside of the liver. This advancement will enable therapeutic access targets that are currently undruggable. These pathways are implicated in inherited retinal disease, autoimmune disease, neurodegenerative disease, cancer, glaucoma, or metabolic disease. In addition to accessing validated but undruggable targets, there are specific advantages to the siRNA mechanism concerning the duration of action and efficacy. These factors differentiate siRNA therapeutics from small molecules, antibodies, and even other oligonucleotide mechanisms. 
DTx has developed a proprietary fatty-acid based technology that enables the delivery of siRNA therapeutics across multiple cell types. The company's platform technology permits oligonucleotide therapeutics to compete with small molecules and other biologics across most indications. It makes possible drug targets and diseases that small molecules and biologics cannot modulate. 

We recently learned that DTx was able to leverage its technology to improve outcomes in a rodent model of Retinitis Pigmentosa. EyeCRO conducted the studies. This development is the first time DTx has demonstrated therapeutic effects in a disease model! These results further underscore the ExSight thesis; the eye is an ideal proving ground for platform technologies with potential non-ophthalmic indications.

Dr. Suckow has done an exemplary job shepherding this technology through the critical early stages. We are thrilled to join Artie, Jeff, the DTx team, and an impressive group of investors in bringing this platform therapeutic modality closer to helping patients. 

The ExSight Ventures team is enthusiastically announcing the launch of the ExSight Ventures Syndicate on AngelList! AngelList is a platform site that enables accredited investors to invest in companies and funds. Syndicates “are single-deal VC funds created to invest in a specific startup.” AngelList Syndicates allow investors “to invest deal-by-deal in specific companies.” AngelList provides a digital platform that will enable both ExSight Ventures and these companies access to additional investors outside of our existing networks. The platform delivers an efficient solution for us to offer and administer co-investment opportunities.
 
Our investment strategy targets the most promising early-stage ophthalmology companies. These prospective investments include innovative companies that span sectors including therapeutics, diagnostics, and devices. The financings these companies are seeking to raise are frequently more than our current investment capabilities permit. We believe we have found a solution that will help us scale our investment capabilities and strengthen our investing abilities.
 
The ExSight Ventures Syndicate will provide our existing investors and other accredited investors access to the types of investments that comprise our current portfolio. Where and when possible, we will use AngelList Syndicates to amplify the firm’s capabilities. Not every opportunity will qualify for the Syndicate nor will it always be possible to obtain an allocation, particularly in deals where ExSight Ventures does not lead. Our AngelList Syndicate will allow our “backers” to help us fund the most innovate companies in vision-care. The AngelList platform will help us in our mission to preserve and restore vision. We have built a very robust pipeline of investment opportunities and are eager to maximize our participation in those opportunities through AngelList Syndicates. 

ExSight’s second fund, 8th Line II held a first close May 27 with participation from many of our existing investors. We also welcomed several new investors. The focus remains the same: to invest in the most innovative companies working to preserve and restore vision. We are quite fortunate to count among our investors in each fund colleagues, family, and friends. The ExSight team is exceptionally proud of what we are building and consider our investors an integral part of our story. Were it not for the support and partnership of each of you this would not be possible. When we came together to form ExSight in 2014, we did so intending to partner with talented founders and committed investors to tackle vision loss. Five plus years into that journey, that dream is becoming a reality. The road to success for startups and the venture funds that invest in them is long. Though still early, we are encouraged by the progress of our portfolio companies and the continued support of our investors. Thank you to each one of you!  
Now, back to work!

​LensGen, an ExSight Ventures portfolio company, was the buzz of this year's American Society of Cataract and Refractive Surgery meeting (“ASCRS”) in San Diego. Members of the ExSight team were in the audience to hear Drs. Eric Donnenfeld, Uday Devgan, and Sumit (Sam) Garg present benefits of the company’s novel Juvene™, (the Complete Premium) IOL, and early results from the “Grail” Study. In addition to the reception LensGen had three high profile presentations during the ASCRS meetings. The first presentation by Uday Devgan, M.D. was given at Cataract/Refractive Subspecialty day. Dr. Devgan, who was also a presenter at the LensGen reception was interviewed after his talk by Healio. Dr. Devgan was the first to introduce ExSight to LensGen several years ago. 
The next presentation by Sam Garg, M.D. was made to a full audience at OIS. Dr. Garg’s talk was front-page news in Eye World ASCRS. The final presentation in this series was given by Eric Donnenfeld, M.D., to a packed house in the main ballroom at the Innovators Lecture session. Each year, ASCRS honors individuals whose innovative ideas have benefited ophthalmologist and their patients at the prestigious Innovators Lecture. Dr. Donnenfeld presented on the Juvene IOL technology and shared the early “Grail” study results. You can watch that presentation in Healio.
It was a very exciting ASCRS for LensGen! We are honored to be a small part of the LensGen story and are very optimistic about their future prospects. Ram and the rest of the LensGen team deserve praise for their dedication and execution. 

​The OIS meetings always keep us busy with a full slate of meetings. These one-day conferences occur around various ophthalmology academy and society meetings throughout the year. OIS unites key constituents in ophthalmic innovation, including industry, entrepreneurial, and clinical leaders all working to develop and commercialize products to preserve and restore vision. The meetings present an opportunity for ExSight to meet with our portfolio companies, learn about new potential investments, and network with other investors and key industry partners. Dr. Rahhal joined investors from KKR, InFocus Capital Partners, and others in a panel discussion led by OIS co-chair, William “Bill” Link of Versant Ventures and Flying L Partners. 

Trefoil Therapeutics, Inc., an early-stage biopharmaceutical company and ExSight Ventures portfolio company, announced their $28 million Series A financing. Trefoil is developing a regenerative approach to treating corneal dystrophies and other diseases. We initially invested in Trefoil's 2016 Series 1 financing and enthusiastically participated in the Series A financing. This financing is a significant milestone in bringing their treatment closer to an approved therapy.

When we first invested we wrote in a note to our investors, "Trefoil's innovations promise to improve patients' lives with a more efficacious treatment and significantly lower risk minimally invasive procedure." Since then, the company has made significant progress in bringing this treatment closer to reality for patients suffering from these disorders. Trefoil has generated preclinical data that has shown "TTHX1114's ability to accelerate corneal clearing in animal models of corneal endothelial dystrophy and enhance healing in corneal chemical injury and herpetic keratopathy." The company has also demonstrated "TTHX1114 stimulates the proliferation and migration of endothelial tissue" in human cornea organ culture models of both healthy and diseased corneas.  

Bios Partners led the round and was joined by Access Biotechnology with participation from all existing investors. The proceeds will provide for the completion of a Phase 2a proof-of-concept study in corneal endothelial dystrophy. Trefoil plans to file an Investigational New Drug (IND) application with the FDA in early 2020 and subsequently begin the clinical trial. This financing will also fund the continued development of a topical formulation of TTHX1114 for the treatment of ulcerative conditions of the cornea. The company plans a second IND submission for corneal epithelial conditions in 2021.
 
The Trefoil team's ability to plan carefully, execute effectively, and communicate clearly have advanced the company's development to this crucial stage. An exceptional and seasoned leadership team, robust preclinical data, and compelling science bode well for getting these breakthrough therapies to patients. We consider ourselves fortunate to be a small part of the Trefoil story. ​Press Release.

​ExSight is pleased to announce Qura, Inc. (“Qura”) as the fifth and final portfolio company for 8th Line Investments, LLC. Qura is developing a miniaturized pressure sensor for the measurement of intraocular pressure (“IOP”) in patients with glaucoma. Glaucoma is a common disease that typically occurs when excess fluid builds up in the eye causing increased IOP damaging the optic nerve and leading to vision loss and blindness. ExSight joins InFocus Capital Partners and Santen Ventures, Inc., a corporate venture capital fund wholly owned by Santen Holdings U.S, Inc. in Qura’s Series A financing.   The funding will be used for product development, testing, design, preclinical studies, and database development.
 
Qura’s QSmart™ wireless implantable pressure sensor (“WIPS”) technology and monitoring system promises to enable smarter treatment decisions based on better information. The miniature WIPS promises continuous monitoring and real-time IOP readings and updates. The data will then be transmitted to a tablet or other handheld device allowing physicians to evaluate glaucoma patients’ treatment in real-time. This technology will lead to better compliance within existing treatment paradigms and a better understanding of the disease. Additional insights gleaned from this data will drive drug and device developments for better treatments.
 
Qura’s CEO Doug Adams has previously remarked, “What makes this minimally invasive micro implant unique is that it will operate autonomously regardless of patient activity. The programmable device collects data based on the physician’s requirement and that data is transmitted to a handheld device or tablet. The physician will now have actionable data on which to base their treatment plans for the patient.”
    
We are excited to be part of the Qura story and their promise to improve treatments available to glaucoma patients!
