As we enter 2024, we remain focused on our mission to develop oral therapies for eye diseases with significant unmet medical needs and are well positioned to execute with our strong balance sheet. We expect to share additional analysis from our Phase 2 Stargardt disease trial at the annual meeting of The Association for Research in Vision and Ophthalmology (ARVO) in May, and to receive one-year interim data from our Phase 3 DRAGON trial later this year. We also look forward to sharing additional enrollment updates on our Phase III PHOENIX trial in GA as the year progresses.” Full Year 2023 Business Highlights and Upcoming Milestones: Clinical Highlights Tinlarebant (LBS-008) is designed to be an oral, potent, once-daily retinol binding protein 4 (RBP4) antagonist that decreases RBP4 levels in the blood and reduces vitamin A (retinol) delivery to the eye without disrupting systemic retinol delivery to other tissues. Vitamin A is critical for normal vision but can accumulate as toxic byproducts in individuals affected with STGD1 and GA (the advanced form of Dry AMD) leading to retinal cell death and loss of vision. Stargardt disease (STGD1): Accumulation of cytotoxic vitamin A byproducts (bisretinoids) has been implicated in the onset and progression of STGD1. Tinlarebant has been granted Fast Track and Rare Pediatric Disease (RPD) designations by the U.S. Food and Drug Administration (FDA) and orphan drug designation (ODD) in the U.S., Europe, and Japan for STGD1. There are currently no FDA-approved treatments for STGD1.LBS-008-CT02 Trial: Completed, open label, 24-month Phase 2 trial in adolescent STGD1 subjects and presented end of trial data at the American Association of Ophthalmology (AAO) annual meeting in November 2023 Tinlarebant was safe and well tolerated with no withdrawals due to adverse eventsThe 24-month data showed a sustained lower atrophic lesion growth in Tinlarebant-treated subjects compared to ProgStar participants possessing similar baseline characteristics (aged ≤18 years) (p<0.001)42% of Tinlarebant-treated subjects (5 out of 12) did not develop atrophic retinal lesionsVisual acuity was stabilized in the majority of subjects during the trial with a mean loss of five letters following 24 months of treatment (a loss of <10 letters is not considered clinically significant) DRAGON Trial: Ongoing, 24 month, randomized (2:1, active: placebo), double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in adolescent STGD1 subjects Completed enrollment with 104 subjects in 11 countriesPrimary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessedInterim data expected in 4Q 2024 Geographic Atrophy (GA): GA, the advanced form of Dry AMD, is a chronic degenerative disease of the retina that leads to blindness in the elderly. Accumulation of toxic vitamin A byproducts (bisretinoids) has been implicated in the progression of GA. There are currently no FDA-approved, orally administered treatments for GA. PHOENIX Trial: Ongoing, 24-month, randomized (2:1, active: placebo; n~430 subjects), double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in patients with GA Primary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessedFirst patient dosed in the third quarter of 2023Has enrolled 56 subjectsInterim data expected at mid-point of the trial Corporate Highlights Completed an underwritten public offering of American Depositary Shares of the Company (“ADSs”) and warrants (the “Follow-on Offering”) for gross proceeds of $30 million in June 2023Initiated an at-the-market offering program of additional ADSs (the “ATM Offering”) with an aggregate offering price of up to $100 million in June 2023Raised $22 million from the exercise of warrants issued in the Follow-on Offering and $29 million from ATM Offering as of December 31, 2023 Audited Full Year 2023 and Unaudited and Unreviewed Fourth Quarter 2023 Financial Results: Cash: As of December 31, 2023, the Company had $88.2 million in cash, as compared with $42.1 million on December 31, 2022. R&D Expenses: For the three months ended December 31, 2023, research and development expenses were $4.9 million compared to $5.2 million for the same period in 2022. The decrease resulted primarily from higher R&D expenses in the fourth quarter of 2022 as the DRAGON trial reached certain milestones in such quarter. For the year ended December 31, 2023, research and development expenses were $24.8 million compared to $8.9 million for the same period in 2022. The increase in research and development expenses was primarily attributable to increases in expenses related to conducting the DRAGON and PHOENIX trials. G&A Expenses: For the three months ended December 31, 2023, general and administration expenses were $2.1 million compared to $1.5 million for the same period in 2022. The increase resulted primarily from an increase in share-based compensation granted in 2023. For the year ended December 31, 2023, general and administration expenses were $6.8 million compared to $4.0 million for the same period in 2022. The increase resulted also primarily from an increase in share-based compensation granted in 2023 and an increase in professional service fees. Net Loss: For the three months ended December 31, 2023, the Company reported a net loss of $7.0 million or ($0.25) per share compared to $6.8 million or ($0.27) per share for the same period in 2022. For the year ended December 31, 2023, the Company reported a net loss of $31.6 million or ($1.19) per share, compared to a net loss of $12.6 million or ($0.63) per share for the same period in 2022.
