Recent Strategic Partnership and Financing Expected to Fund Operations Through 2026

Encinitas, California--(Newsfile Corp. - March 25, 2024) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") today announced its 2023 financial results and provided an update on its retinal disease development pipeline. The Company's major initiatives planned for 2024 are to initiate Phase 2 clinical development of KIO-301, a small molecule photoswitch, for the treatment of inherited retinal diseases, starting with retinitis pigmentosa (RP); and further development of KIO-104, an intravitreal, anti-inflammatory for treatment of non-infectious uveitis. The $16 million upfront payment from Kiora's development and commercialization partnership with Théa Open Innovation (TOI) for KIO-301 and its $15 million private placement are expected to be sufficient to fund the Company through 2026, excluding any potential partnership milestones or warrant exercises.

"Our greatest priorities this year are to advance KIO-301 and KIO-104 to assess their further potential to benefit patients," said Brian M. Strem, Ph.D., chief executive officer of Kiora. "Both products are clinically validated drug candidates based on proprietary and innovative small molecules targeting rare retinal diseases with large unmet needs.

Kiore's pipeline of drug candidates against rare retinal diseases.

"KIO-301 could potentially become the first vision restoring option for patients with inherited retinal degenerative diseases like RP. Ongoing development will be collaboratively guided and fully funded by our partner, TOI. Should KIO-301 gain marketing authorization, it would provide Kiora with meaningful commercial milestones and royalties up to the low 20s (%) with a partner who has a proven track-record of leadership in the eye space. Working with TOI, we are finalizing details of the randomized, double-masked, controlled, dose-ascending Phase 2 trial in RP and look forward to providing more specifics on expected enrollment and results timelines.

"The balance sheet provides us the financial ability to fund further development of KIO-104 for the treatment of posterior non-infectious uveitis. Because non-infectious uveitis can be sight threatening, there is a strong market need for new, steroid sparing therapeutic approaches. The active compound in KIO-104 is a highly potent, disease modifying anti-inflammatory agent belonging to a class of drugs helping hundreds of thousands of patients with systemic autoimmune diseases including multiple sclerosis and rheumatoid arthritis. By delivering KIO-104 directly to the eye, we believe we can reduce the negative effects of retinal inflammation without the associated potential side effects of systemic anti-inflammatory drugs or chronic steroid exposure. Beyond non-infectious uveitis, the mechanism of action of KIO-104 could apply to other retinal conditions, such as proliferative vitreoretinopathy (PVR), a complication following retinal detachment repair, where nonclinical work is ongoing."

"Orphan indications involve efficient, cost-effective paths to market," added Melissa Tosca, EVP Finance. "For 2024, we expect to increase our R&D spend, with expenses for KIO-301 offset by quarterly reimbursement from TOI. Further, we anticipate G&A expenses to remain relatively flat for the year. We believe this balances our desire to achieve meaningful development while maintaining a strong cash position expected to fund operations through 2026."

Kiora has strengthened its fundamentals by advancing its pipeline, entering a strategic partnership, and strengthening its balance sheet.

Achieved and Upcoming Milestones:

Notable milestones that Kiora achieved in 2023 and year-to-date 2024 include the following:

KIO-301

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

• Completed enrollment and reported topline results from ABACUS-1. Results demonstrated KIO-301 was safe and tolerable with improvements consistent across multiple measures, including improved visual field, visual acuity, and functional vision (navigating in real-world simulations). In addition, functional MRI measures showed reactivation of the specific regions of the brain responsible for vision.

• Held a Type B, pre-IND meeting with the US FDA regarding Kiora's proposed clinical development plans and received feedback on trial design, including approvable endpoints, details for the control group, and outstanding non-clinical requirements, all consistent with Kiora's current plans.

KIO-100 Family (KIO-104, KIO-101)

• The 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 the placebo group.

• Granted US and European patents covering local ocular delivery of the KIO-100 family of non-steroidal, anti-inflammatory small molecules.

Kiora anticipates achieving the following clinical and regulatory milestones:

KIO-301

• Report additional ABACUS-1 data, including quantitative functional MRI measures showing reactivated brain activity in the visual cortex in a time-dependent manner.

• Complete comprehensive design, under the joint Kiora-TOI steering committee, of a randomized, controlled, multicenter, double-masked, dose-ascending Phase 2 study of KIO-301 in retinitis pigmentosa with initiation expected as early as the fourth quarter of 2024.

• Pursue Orphan Drug Designations for KIO-301 for choroideremia and Stargardt disease in the US and EU.

KIO-104

• Initiate supportive non-clinical research to inform and optimize Phase 2 and registration studies in 2024.

• Plan a multicenter, randomized, double-masked, dose-ascending Phase 2 study of KIO-104 for the treatment of non-infectious uveitis.

• Perform additional pre-clinical proof-of-concept studies of KIO-104 in proliferative vitreoretinopathy, a rare but serious complication of retinal reattachment procedures beginning in 2024.

Financial Results

Kiora ended the year with $2.5 million in cash and cash equivalents and $2.0 million in tax receivables. In February of 2024, Kiora received an additional $16 million for an upfront payment from TOI and raised $13.8 million in net proceeds from a private placement offering. The Company's cash and cash equivalents as of March 24, 2024, exceeds $30 million and the Company believes this will fund operations through 2026.

In 2023, research and development expenses were $4.0 million, net of $1.7 million in offsetting tax credits, compared to $3.5 million, net of $1.5 million in offsetting tax credits, for 2022. Research and development expenses for the fourth quarter of 2023 were $1.1 million, net of $0.5 million in offsetting tax credits, compared to $0.8 million, net of $0.4 million in offsetting tax credits for the fourth quarter of 2022. The increase in R&D in 2023 was primarily due to greater investment in clinical trial-related activities for KIO-301 and personnel-related expenses for the R&D team. Kiora anticipates R&D expenses will increase as it begins planning and enrollment of patients in Phase 2 clinical trials, with trial-related expenses for KIO-301 offset by reimbursement from TOI.

General and administrative expenses for 2023 were $4.7 million compared to $8.3 million for 2022. General and administrative expenses for the fourth quarter of 2023 were $0.9 million, compared to $2.8 million in the fourth quarter of 2022. The reduction in general and administrative expenses for the full year and fourth quarter of 2023 were primarily related to lower professional service fees, driven by reduced external accounting and auditing services. Kiora expects that general and administrative expenses will remain relatively consistent for the near future.

Net loss was $12.5 million for 2023 compared to $13.6 million for 2022. Net loss was $2.3 million for the fourth quarter of 2023 compared to $2.5 million for the fourth quarter of 2022.
