DLL3, or delta-like ligand 3, has emerged as a promising therapeutic target for specific malignancies. DLL3, which is generally not expressed in most normal tissues, is overexpressed in neuroendocrine malignancies such as small cell lung cancer (SCLC). Thus, targeting DLL3 provides an approach for more specific cancer treatment, particularly for neuroendocrine cancer patients who have few therapeutic options. DLL3 regulates the Notch signaling pathways, which control cell differentiation. In healthy tissues, DLL3 expression is strictly regulated. However, in cancer, abnormal DLL3 expression has been linked to tumor start and development. DLL3 is found in up to 80% of small cell lung cancer tumors but has little expression in normal adult tissues, making it a promising therapeutic target. Pharmaceutical companies are developing targeted therapeutics for DLL3 using a variety of ways. Bispecific antibodies, primarily as T cell engagers, have advanced the most in clinical research and testing. Bispecific T cell engagers bridge the gap between cancer cells and immune cells by simultaneously connecting with both, diverting endogenous T-cell populations to cells expressing DLL3 and inducing tumor cell death. This method aids in initiating a focused attack on specific cancer cells while reducing collateral damage to healthy cells. Download Insight: Amgen created Tarlatamab utilizing its patented BiTE (bispecific T-cell engager) technology. In the phase 2 DeLLphi-301 trial, which assessed the objective response rate, duration of response, disease control rate, progression-free survival, and overall survival following Tarlatamab treatment, an objective response rate of 40% and disease control rate of 63% were found. All participants in the study had advanced-stage SCLC, and had received at least two lines of previous treatment, including platinum-doublet chemotherapy. Based on these promising results, Amgen filed a biologics license application (BLA) at the US FDA for the treatment of patients with advanced small cell lung cancer (SCLC), which granted it Priority Review in December 2023, with the Prescription Drug User Fee Action date of June 12, 2024. Other approaches to DLL3 include cell therapies, such as Tianjin Medical University Cancer Institute and Hospital's DLL3-CAR-NK cell therapy, and Legend Biotech's LB2102, a DLL3-CAR-T cell therapy. Another example is antibody-drug conjugates, which paved the way for the development of DLL3 targeting therapies after studies using Rovalpituzumab Tesirine proved the anticancer effects of DLL3 targeting. While most DLL3 targeted therapies are still in their early phases, Tartalamab has demonstrated promise thus far, as seen by its multiple designations. DLL3 targeted treatments have significant implications for cancer treatment, with the potential to succeed where previous therapies have failed. With further study and clinical trials, DLL3 targeted treatments have the potential to improve patient survival in neuroendocrine cancers.

Selling and Distribution Expenses Selling and distribution expenses for the three months and year ended December 31, 2023, were $33.7 million and $94.2 million, respectively, compared to $25.8 million and $93.4 million for the three months and year ended December 31, 2022. The increase of $7.9 million and $0.8 million for the three months and year ended, respectively were due to costs associated with commercial activities for cilta-cel. Other Income and Gains Other income and gains for the three months and year ended December 31, 2023, were $18.5 million and $58.1 million, respectively, compared to $7.4 million and $12.0 million for the three months and year ended December 31, 2022. The increase of $11.1 million and $46.1 million for the three months and year ended, respectively, were primarily attributable to an increase in interest income and gain on investments. Other Expenses Other expenses for the three months and year ended December 31, 2023, were $38.4 million and $28.5 million, respectively, compared to $0.3 million and $9.8 million for the three months and year ended December 31, 2022. The increase of $38.1 million and $18.7 million for the three months and year ended, respectively, were primarily due to unrealized foreign currency exchange loss. Finance Costs Finance costs for the three months and year ended December 31, 2023, were $5.8 million and $21.8 million, respectively, compared to $4.9 million and $10.8 million for the three months and year ended December 31, 2022. The increase of $0.9 million and $11.0 million for the three months and year ended, respectively, were primarily due to interest on advance funding, which is interest-bearing borrowings funded by Janssen under the Janssen Agreement and constituted of principal and applicable interests upon such principal. Fair Value (Loss)/Gain of Warrant Liability There was no fair value (loss)/gain of warrant liability for the three months ended December 31, 2023, compared to a loss of $9.3 million for the three months ended December 31, 2022. Fair value loss of warrant liability for the year ended December 31, 2023, was $85.8 million, compared to a fair value gain of $20.9 million for the year ended December 31, 2022. The decrease of $9.3 million for the three months ended, was because the warrant was exercised on May 11, 2023. The increase of $106.7 million for the year ended, was due to the fair value loss recorded on the full exercise of the warrant we issued to an institutional investor in May 2021, which took place on May 11, 2023. Loss for the Period For the three months ended December 31, 2023, net loss was $144.8 million, or $0.40 per share, compared to net loss of $135.9 million, or $0.41 per share, for the three months ended December 31, 2022.
