Dr. van de Goor has served as a consultant to ONL since 2014.Ms. Johnson, who joined ONL in late 2014 as senior vice president of operations, will now serve as the company’s senior vice president of operational excellence. In this new role, she will be responsible for overseeing efforts to scale the company’s operational processes and entrepreneurial culture to align with the ongoing advancement of the ONL1204 program. Ms. Johnson has over 20 years of pharmaceutical industry experience with responsibilities ranging from principal research scientist through development team leader. Prior to joining ONL, she served as an executive director for Pfizer Worldwide Development. In that role, she led global, multi-disciplinary teams in the development of more than 30 clinical candidates across a wide range of therapeutic areas and through all phases of drug development. During her final two years with Pfizer, Linda served as a global leader, overseeing the development and clinical activities for a therapeutic portfolio of 10 – 15 candidates.Since joining ONL in 2015, Dr. Kocab has played a key role supporting senior leadership in a range of efforts spanning both corporate and research activities. Importantly, he recently spearheaded the development and submission of grant applications to the National Institutes of Health and Orphan Drug applications to the United States Food and Drug Administration. Dr. Kocab’s research background involves cell signaling pathways related to cell death and inflammation. Specifically, he has undertaken research into the signaling from receptors closely related to Fas, as well as the effector proteins involved in regulating these processes. This expertise will be particularly relevant in his new role as he continues to build ONL’s fundamental understanding of how Fas inhibitors may protect key retinal cells, including photoreceptors, from cell death that occurs in a range of retinal diseases and conditions.About ONL1204ONL1204 is a novel, first-in- class small molecule Fas inhibitor designed to protect key retinal cells, including photoreceptors, from cell death that occurs in a range of retinal diseases and conditions.

ONL Therapeutics Receives Nearly $1.0 Million Grant from National Eye Institute for Continued Advancement of ONL1204 Program

Grant Funding Combined with Recent Financing Will Support Final IND-Enabling Studies for Novel Retinal Disease Drug Candidate

ANN ARBOR, MI – March 21, 2017

ONL Therapeutics, Inc., a biopharmaceutical company developing novel therapies for preserving sight in a range of retinal diseases, today announced that the company has been awarded a Commercialization Readiness Pilot (CRP) grant of approximately $1.0 million from the National Eye Institute (NEI) to continue advancement of ONL1204, the company’s lead therapeutic candidate. ONL1204 is a novel, first-in- class small molecule Fas inhibitor designed to protect key retinal cells, including photoreceptors, from cell death that occurs in a range of retinal diseases and conditions. Death of these retinal cells, both direct and via inflammatory signaling, is the root cause of vision loss and the leading cause of blindness.

ONL intends to use the funding from this CRP grant to support the remaining ONL1204 preclinical development activities required for submission of an investigational new drug (IND) application. The company is initially developing ONL1204 for the treatment of retinal detachment, a condition for which the compound has been granted orphan drug designation by the United States Food and Drug Administration (FDA). While initial development efforts are focused on retinal detachment, preclinical in vivo data along with a growing body of literature support potential application in several additional ocular diseases including age related macular degeneration (AMD).

ONL has previously received Phase I and Phase II Small Business Innovation Research (SBIR) research grants from the NEI that have helped support the company’s preclinical development work to date. This includes establishment of proof-of- concept for Fas inhibition in rodent models of retinal detachment, the identification and formulation of ONL1204, and initial pharmacokinetic and toxicology research for the compound. The CRP program which has awarded the latest grant is designed to provide additional financial resources to assist companies in transitioning previously funded SBIR Phase II projects to the commercialization stage.

“We are excited and grateful for this additional NEI grant funding as it allows ONL to build upon the promising preclinical work that we have conducted to date. The area of retinal cell protection represents a critical unmet medical need that we believe can have an important impact on the preservation of vision for patients with a range of ocular diseases and conditions,” said John Freshley, chief executive officer of ONL Therapeutics. “By providing the funds that will help us advance ONL1204 to the point of IND filing, the NEI is playing a key role in research that may one day make a difference in the lives of ocular disease patients. We appreciate their support and look forward to completing the important work that this grant is making possible.”

In addition to the CRP grant, ONL has also recently raised more than $1.0 million through an interim financing involving both existing and new investors, including Novartis and Invest Michigan. Dr. Cynthia Grosskreutz, Global Translational Medicine Head for Ophthalmology at Novartis joins the ONL Board of Directors as an observer. These funds will also be used to complete IND-enabling activities and advance ONL1204 toward human clinical trials. “The CRP grant, renewed commitment from our existing investors, and new commitment from investors such as Novartis validates the clinical and commercial potential of our technology and provides ONL access to unique ocular drug development expertise,” stated Mr. Freshley. “The combined funding will accelerate our development efforts aimed at moving ONL1204 into the clinic.”
