Recent Highlights

• Announced the publication of data evaluating Annamycin's performance as an anthracycline designed to avoid the cardiotoxicity typically associated with currently prescribed anthracyclines, in a manuscript titled, "Anthracycline-induced cardiotoxicity – are we about to clear this hurdle?," published in the peer-reviewed European Journal of Cancer.
• Received approval in Italy to conduct and dosed first subjects for Phase 1/2 trial evaluating Annamycin in combination with cytarabine (Ara-C) for the treatment of acute myeloid leukemia (AML).
• Announced final topline successful safety data – setting a recommended Phase 2 dose - and reported 80% overall response rate in final cohort from the European Phase 1 trial evaluating Annamycin as a single agent treatment of Refractory AML.

Summary of Financial Results for the Full Year 2022 

Research and development (R&D) expense was $19.0 million and $14.4 million for the years ended December 31, 2022 and 2021, respectively. The increase in R&D of $4.6 million is mainly related to increased clinical trial activity, and costs related to manufacturing of additional drug product.

General and administrative (G&A) expense was $11.5 million and $8.4 million for the years ended December 31, 2022 and 2021, respectively. The increase in G&A of $3.1 million was mainly attributable to an increase in regulatory and legal services, and consulting & advisory fees.

The net loss for the year ended December 31, 2022 was $29.0 million, which included non-cash gains of $1.3 million on warrants in 2022 as compared to $6.7 million in the prior year and approximately $2.3 million of stock-based compensation expense in 2022 as compared to $2.4 million in 2021.

As of December 31, 2022, we had cash and cash equivalents of $43.1 million and prepaid expenses and other current assets of $2.5 million. The Company believes that this cash is sufficient to meet its projected operating requirements into the third quarter of 2024.
