Phase 2 trial for KIO-301 for the treatment of retinitis pigmentosa, in partnership with Théa Open Innovation, expected to be initiated in Q4 2024

Phase 2 clinical trial for KIO-104 for retinal inflammation expected to begin in 2025

Ended Q1 2024 with $31.3 million in cash and cash equivalents, providing an expected runway of more than two years

Encinitas, California--(Newsfile Corp. - May 10, 2024) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") announces first quarter 2024 financial results and updates on its development pipeline of treatments for retinal disease.

"Our balance sheet and strategic partnership with Théa Open Innovation (TOI) put us in a strong position to advance our two retinal programs, KIO-301 and KIO-104, into mid-stage clinical trials," said Brian M. Strem, Ph.D., chief executive officer of Kiora. "Both compounds, given their mechanisms of action, have the potential to address multiple diseases; KIO-301 for the treatment of inherited retinal disorders, and KIO-104 for the treatment of retinal inflammatory diseases. Our upcoming Phase 2 ABACUS-2 trial of KIO-301 for the treatment of retinitis pigmentosa, is a multi-center double-masked, randomized, controlled, multiple-dose study performed in collaboration with TOI.

"As part of our partnership, TOI will fund the remaining clinical development of KIO-301 across multiple indications, allowing us to efficiently invest our capital in the development of KIO-104 to treat retinal inflammatory diseases. KIO-104 may address the established need for eye treatments that spare the complications of chronic steroid use and/or systemic anti-inflammatory drugs. Clinical proof-of-concept for KIO-104 in the treatment of non-infectious uveitis, a rare retinal inflammatory condition, has been established with recently published results from a Phase 1/2a study. Prior to initiating a Phase 2 trial, we are conducting additional investigational new drug (IND) enabling work. Beyond non-infectious uveitis, the mechanism of action of KIO-104 could apply to other retinal conditions, such as macular edema, and proliferative vitreoretinopathy (PVR), a serious complication following retinal detachment repair."

"In the first quarter, we executed a strategic partnership with TOI, which included a $16 million upfront payment, and raised $15 million from an equity offering," added Melissa Tosca, EVP Finance. "These developments substantially strengthened our cash position, allowing us to advance our two exciting programs while maintaining G&A expenses, and provides a runway of greater than two years. The TOI upfront payment was recognized entirely in the first quarter as collaboration revenue and we expect future development and regulatory milestone payments to be treated similarly."

Milestones achieved in the first quarter and year-to-date 2024 include the following:

KIO-301

• Entered a strategic partnership granting TOI exclusive worldwide co-development and commercialization rights, excluding Asia, to KIO-301 for the treatment of retinal degenerative diseases. Under the terms of the agreement, Kiora received an upfront payment of $16 million, recognized as collaboration revenue, and is eligible to receive up to an additional $285 million in development, regulatory, and commercial milestones; tiered royalties of up to low 20 percent on net sales; and full reimbursement of future KIO-301 research and development expenses.

• Reported quantitative functional MRI results at the Association of Research in Vision and Ophthalmology (ARVO) annual conference from ABACUS-1, showing a statistically significant increase in neural activity over baseline specifically within the brain's visual processing center. This increase in observed brain activity was time-dependent and concordant with previously reported improvements in visual field, visual acuity, and functional vision.

KIO-104

• Publication of results from a Phase 1 double-masked study of KIO-101 in the medical journal Pharmaceutics, documenting a 12-day treatment of KIO-101 topically at multiple doses was well tolerated in healthy volunteers and patients with inflammation of the eye. There was a significant decrease in conjunctival hyperemia in the treatment group compared to placebo.

• Initiated Investigational New Drug enabling preclinical work in support of planned phase 2 retinal inflammation clinical trial.

Kiora anticipates achieving the following clinical and regulatory milestones:

Financial Results Highlights

Kiora ended the first quarter of 2024 with $31.3 million in cash and cash equivalents plus $1.8 million in research and development incentive tax credits and $0.2 million in collaboration receivables from TOI.

Revenue was $16.0 million for the first quarter of 2024, compared to no revenue in the first quarter of 2023. The revenue comes from collaboration revenue as part of an upfront payment from TOI connected to the strategic development and commercialization partnership.

Research and development expenses were $1.5 million, net of $0.2 million in offsetting credits related to expenses for KIO-301 which will be reimbursed by TOI, for the first quarter of 2024, compared to $0.4 million, net of $0.3 million in offsetting tax credits, for the first quarter of 2023. The increase was primarily due to a one-time licensing payment made to the University of California related to a sublicense fee of $0.7 million, and a decrease of $0.3 million in R&D tax credits due to reduced credit-eligible expenses given the KIO-301 expenses are now being reimbursed by TOI.

General and administrative expenses were $1.3 million for the first quarter of 2024, compared to $1.3 million for the first quarter of 2023.

Net income was $13.5 million for the first quarter of 2024 compared to a net loss of $1.9 million for the first quarter of 2023. The change in income is attributable to the recognition of $16 million in collaboration revenue.
