Kiora Pharmaceuticals Reports Q3 2023 Results; Expanding Clinical Development of KIO-301 for Inherited Retinal Diseases Based on Encouraging Results of ABACUS-1 Study in Retinitis Pigmentosa

Encinitas, California--(Newsfile Corp. - November 9, 2023) - Kiora Pharmaceuticals, Inc. (NASDAQ: KPRX) ("Kiora" or the "Company") today announced its third quarter 2023 financial results and is providing an update on its plans to advance clinical development of KIO-301 for other inherited retinal diseases.

On November 4, 2023, Kiora reported results from the ABACUS-1 study, a Phase 1b first-in-human clinical trial of the Company's molecular photoswitch, KIO-301, in patients with late-stage retinitis pigmentosa (RP). The key findings from ABACUS-1 demonstrated that KIO-301 is safe & tolerable in this population and further showed significant improvements in visual field and a concordance of trended improvements in visual acuity and functional vision. Functional MRI demonstrated increased brain activity in visual cortex.

Based on these findings, the Company will expand clinical development of KIO-301 for multiple inherited retinal diseases. This includes the initiation of a Phase 2 controlled, double-masked, randomized, ascending-dose trial in up to 20 patients with RP dosed monthly over 90 days (ABACUS-2). In addition, Kiora plans to initiate two additional Phase 2 studies, one for Choroideremia (CHM) and another Stargardt disease, being able to leverage synergies for efficient trial execution. CHM and Stargardt disease are inherited retinal diseases with a similar pathology to RP and may qualify of Orphan Drug Designation.

"Based on our internal assessment and input from our scientific and medical advisors, we will initiate ABACUS-2 in the first half of 2024, with the goal of confirming both efficacy and safety in a multi-dose, double-masked, controlled clinical trial," said Brian M. Strem, Ph.D., chief executive officer of Kiora. "Ahead of this trial, we have plans to meet with the FDA in Q4 2023 to ensure alignment on study designs, endpoints and additional requirements to perform studies in the US and Europe for RP as well as other inherited retinal diseases like CHM and Stargardt disease. This strategy represents a cost-effective and expedited path to bring a potential new treatment for multiple inherited retinal diseases for which there are currently no available therapies."

Achieved and Upcoming Milestones:

The milestones that Kiora achieved in the first half of 2023 include the following:

• KIO-301: Reported encouraging topline results from ABACUS-1 at the American Academy of Ophthalmology 2023 Annual Meeting on November 4, 2023
• KIO-301: Received Investigational New Drug Application approval in Australia to enroll additional patients in an ABACUS-1 study expansion to evaluate KIO-301 in patients with late-stage CHM
• KIO-301: Entered a partnership with the Choroideremia Research Foundation to support strategic clinical development of KIO-301 in Choroideremia
• KIO-201: Reported results from a Phase 2 Persistent Corneal Epithelial Defect study at the ARVO Annual Meeting in Q2 2023
• KIO-100 family: granted U.S. and European Patents covering local ocular delivery of the KIO-100 family of non-steroidal, anti-inflammatory small molecules.
• Business: Raised $6.3 million in funding to extend runway into May 2024
• Business: Received $1.2 million of research tax incentives from Australia and Austria
• Business: Appointed Praveen Tyle, PhD as its Chairman of the Board of Directors.

The Company anticipates achieving the following clinical and regulatory milestones:

• KIO-301: Discuss the development path for KIO-301 in RP with the FDA in a type B pre-IND meeting in Q4 2023
• KIO-301: Initiate the ABACUS-2 phase 2 trial of KIO-301 in RP
• KIO-301: Initiate a Phase 2 trial for Choroideremia
• KIO-301: Initiate a Phase 2 trial for Stargardt disease
• KIO-301: Pursue Orphan Drug Designations for KIO-301 for Choroideremia and Stargardt Disease in the USA and EU
• KIO-104: Pursue Orphan Drug Designation for KIO-104 for Posterior Non-Infectious Uveitis in the USA

Financial Results

In the first nine months of 2023, research and development expenses were $4.1 million, exclusive of $1.2 million in offsetting tax credits, compared to $3.8 million, exclusive of $1.2 million in offsetting tax credits, for the first nine months of 2022. Research and development expenses for the third quarter of 2023 were $1.6 million, exclusive of $0.5 million in offsetting tax credits, compared to $2.4 million, exclusive of $1.1 million in offsetting tax credits for the third quarter of 2022. In the third quarter of 2022, a year-to-date catch-up for the 2022 research tax credit was recorded, resulting in an additional $0.7 million in out-of-period expense. The increase for the first nine months was primarily due to clinical trial-related expenses while the decline in the third quarter was primarily due to the completion of the ABACUS study.

General and administrative expenses for the first nine months of 2023 were $3.8 million compared to $5.5 million for the first nine months of 2022. General and administrative expenses for the third quarter of 2023 were $1.4 million, compared to $2.0 million in the third quarter of 2022. The reduction is attributable to reduced consulting fees, lower facilities cost due to the consolidation of offices, and lower personnel costs due to staffing optimization and benefit cost savings.

Net loss was $10.2 million for the first nine months of 2023 compared to $11.1 million for the first nine months of 2022. Net loss was $5.8 million for the third quarter of 2023 compared to $5.1 million for the third quarter of 2022. This increase in the first nine months and third quarter of 2023 compared to the same periods in 2022 was primarily due to a non-cash impairment of in-process R&D, related to the strategic decision to stop internal development activities leading to commercialization for KIO-101 and KIO-201. The Company is seeking partnership opportunities for the continued development of these programs. The decrease in net loss before the non-cash impairment in the nine and three months ended Sept 30, 2023, compared to the same periods in 2022 was primarily due to lower personnel, consulting and facilities expenses.

Kiora ended the quarter with $5.4 million in cash and cash equivalents and $1.3 million in tax receivables. Additionally, Kiora may in the future draw on a $10 million equity line of credit (subject to certain limitations), of which there is up to approximately $9.6 million available.
