We were also excited to begin development of gedatolisib for patients with metastatic castration resistant prostate cancer this past year. Enrollment has begun in our Phase 1b/2 trial evaluating gedatolisib in combination with darolutamide, and we look forward to sharing preliminary data from this trial in the first half of 2025.”

Fourth Quarter 2023 Business Highlights and Other Recent Developments

Fourth Quarter and Full Year 2023 Financial Results

Unless otherwise stated, all comparisons are for the fourth quarter and full year ended December 31, 2023, compared to the fourth quarter and full year ended December 31, 2022.

Total operating expenses were $19.7 million for the fourth quarter of 2023, compared to $11.6 million for the fourth quarter of 2022. Operating expenses for the full year 2023 were $66.2 million, compared to $39.4 million for the full year 2022.

Research and development (R&D) expenses were $18.1 million for the fourth quarter of 2023, compared to $10.6 million for the prior-year period. Of the approximately $7.5 million increase in R&D expenses, $6.8 million primarily related to activities supporting the VIKTORIA-1 Phase 3 trial and the initiation of the CELC-G-201 Phase 1b/2 clinical trial, and $0.7 million was related to increased employee and consulting expenses.

R&D expenses for the full year 2023 were $60.6 million, compared to $35.3 million for the prior year. Of the approximately $25.3 million increase in R&D expenses, $22.9 million was related to activities supporting the VIKTORIA-1 Phase 3 trial and the initiation of the CELC-G-201 Phase 1b/2 clinical trial. The remaining $2.4 million increase in R&D expenses was related to increased employee and consulting expenses.

General and administrative (G&A) expenses were $1.6 million for the fourth quarter of 2023, compared to $1.0 million for the prior-year period. Employee-related expenses accounted for $0.5 million of the increase. The remaining increase resulted from professional fees and other expenses associated with compliance related activities that support financing and clinical operations.

G&A expenses for the full year 2023 were $5.6 million, compared to $4.1 million for the prior year. Of the approximately $1.5 million increase in G&A expenses, $1.1 million was related to increased employee-related expenses, and $0.4 million was related to professional fees and other expenses associated with compliance related activities that support financing and clinical operations.

Net loss for the fourth quarter of 2023 was $18.8 million, or $0.65 loss per share, compared to a net loss of $11.6 million, or $0.69 loss per share, for the fourth quarter of 2022. Net loss for the full year 2023 was $63.8 million, or $2.69 loss per share, compared to a net loss of $40.4 million, or $2.64 loss per share, in 2022. Non-GAAP adjusted net loss for the fourth quarter of 2023 was $17.6 million, or $0.61 loss per share, compared to non-GAAP adjusted net loss of $10.3 million, or $0.61 loss per share, for the fourth quarter of 2022. Non-GAAP adjusted net loss for the full year 2023 was $57.8 million, or $2.44 loss per share, compared to non-GAAP adjusted net loss of $35.0 million, or $2.27 loss per share, for 2022. Non-GAAP adjusted net loss excludes stock-based compensation expense, non-cash interest expense, and non-cash interest income. Because these items have no impact on Celcuity’s cash position, management believes non-GAAP adjusted net loss better enables Celcuity to focus on cash used in operations. For a reconciliation of financial measures calculated in accordance with generally accepted accounting principles in the United States (GAAP) to non-GAAP financial measures, please see the financial tables at the end of this press release.

Net cash used in operating activities for the fourth quarter of 2023 was $18.5 million, compared to $9.5 million for the fourth quarter of 2022. Net cash used in operating activities for the full year 2023 was $53.8 million, compared to $36.0 million for the full year 2022.

In October of 2023, Celcuity closed a private placement of equity that resulted in gross proceeds of approximately $50 million. In December 2023, Celcuity closed on an additional $15 million of gross proceeds through its at-the-market offering. The Company expects to use the net proceeds to advance the clinical development of gedatolisib and for general corporate purposes.

At December 31, 2023, Celcuity reported cash, cash equivalents and short-term investments of $180.6 million. We expect cash, cash equivalents, investments and available funds under our debt facility to provide adequate capital to fund current operational activities into the first half of 2026.

About Celcuity

Celcuity is a clinical-stage biotechnology company focused on development of targeted therapies for treatment of multiple solid tumor indications. The company’s lead therapeutic candidate is gedatolisib, a potent, pan-PI3K and mTOR inhibitor. Its mechanism of action and pharmacokinetic properties are highly differentiated from other currently approved and investigational therapies that target PI3K or mTOR alone or together. A Phase 3 clinical trial, VIKTORIA-1, evaluating gedatolisib in combination with fulvestrant with or without palbociclib in patients with HR+/HER2- advanced breast cancer is currently enrolling patients. More detailed information about the VIKTORIA-1 study can be found at ClinicalTrials.gov. A Phase 1b/2 clinical trial, CELC-G-201, evaluating gedatolisib in combination with darolutamide in patients with metastatic castration resistant prostate cancer, is enrolling patients. The company’s CELsignia companion diagnostic platform is uniquely able to analyze live patient tumor cells to identify new groups of cancer patients likely to benefit from already approved targeted therapies.

Cautionary Statement Regarding Non-GAAP Financial Measures

This press release contains references to non-GAAP adjusted net loss and non-GAAP adjusted net loss per share. Management believes these non-GAAP financial measures are useful supplemental measures for planning, monitoring, and evaluating operational performance as they exclude stock-based compensation expense, non-cash interest expense, and non-cash interest income from net loss and net loss per share. Management excludes these items because they do not impact Celcuity’s cash position, which management believes better enables Celcuity to focus on cash used in operations. However, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share are not recognized measures under GAAP and do not have a standardized meaning prescribed by GAAP. As a result, management’s method of calculating non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may differ materially from the method used by other companies. Therefore, non-GAAP adjusted net loss and non-GAAP adjusted net loss per share may not be comparable to similarly titled measures presented by other companies. Investors are cautioned that non-GAAP adjusted net loss and non-GAAP adjusted net loss per share should not be construed as alternatives to net loss, net loss per share or other statements of operations data (which are determined in accordance with GAAP) as an indicator of Celcuity’s performance or as a measure of liquidity and cash flows.
