The net increase in cash was primarily a result of cash inflows from approximately $316 million of net proceeds from our public offering of common stock completed in February including partial exercise of underwriters’ option to purchase additional shares. We currently expect cash and cash equivalents to be sufficient to fund operations into the first half of 2027. R&D Expenses: Research and development expenses were $31.9 million for the second quarter of 2024, as compared to $23.6 million for the second quarter of 2023. This increase was driven by the progression of our existing clinical trials, primarily Phase 2 4D-150 trials in wet AMD and DME, along with increased payroll and stock-based compensation expense due to higher headcount. G&A Expenses: General and administrative expenses were $10.6 million for the second quarter of 2024, as compared to $8.8 million for the second quarter of 2023. Net Loss: Net loss was $35.0 million for the second quarter of 2024, as compared to net loss of $29.6 million for the second quarter of 2023.
