Looking ahead, we are on track to complete Part A of our GD2-SADA Phase 1 clinical trial in the fourth quarter of this year with a data readout to follow and are on track to dose the first patient in our CD38-SADA Phase 1 in Non-Hodgkin's Lymphoma trial in the second half of this year."

Presented preclinical GD2-SADA data at the Society of Nuclear Medicine & Molecular Imaging 2024 annual Meeting on June 8-11, 2024, in Toronto, Canada.

Financial Results Revenues Total net product revenues were $22.8 million and $42.2 million for the quarter and six months ended June 30, 2024, which represented an increase of 10% and 3%, respectively, over $20.8 million and $41.0 million in the comparable periods of 2023. DANYELZA total net product revenues of $22.8 million in the second quarter of 2024, represented a 10% increase compared to the second quarter of 2023, primarily driven by increased international revenues. Y-mAbs' international DANYELZA net product revenues were $7.6 million for the three months ended June 30, 2024, an increase of 55% over $4.9 million in the comparable period in 2023. The increase of net product revenue in the quarter ended June 30, 2024, compared to the quarter ended June 30, 2023, was a result of increased volume from Western Europe, as well as the commercial launch for Brazil and Mexico in Latin America. U.S. DANYELZA net product revenues were $15.2 million and $15.9 million for the three months ended June 30, 2024 and 2023, respectively, representing a 4% decline driven by a volume decrease due to the launch of competing therapy in another class of agents and some ongoing clinical trial activities. The Company's total net product revenue was $42.2 million for the six months ended June 30, 2024, as compared to $41.0 million in the comparable period in 2023. The 3% increase was primarily driven by a $1.2 million increase in the U.S. DANYELZA net product revenue in the six months ended June 30, 2024, while international net product revenue was relatively flat. As of June 30, 2024, Y-mAbs has delivered DANYELZA to 65 centers across the U.S. since initial launch, with two new accounts added in the U.S. in the second quarter of 2024. During the quarter ended June 30, 2024, approximately 67% of the vials sold in the U.S. were sold outside of Memorial Sloan Kettering Cancer Center ("MSK"), compared to 60% in the first quarter ended March 31, 2024. The Company did not have license revenue for the quarters ended June 30, 2024 and 2023. The Company had license revenues of $0.5 million for the six months ended June 30, 2024, from our distribution partner, Adium, related to our acceptance of the price for DANYELZA in Brazil from the Brazilian Medicines Market Regulation Chamber. There was no license revenue recorded for the six months ended June 30, 2023. Operating Costs and Expenses Cost of Goods Sold Cost of goods sold was $3.0 million and $4.6 million for the quarter ended June 30, 2024 and 2023, respectively. Cost of goods sold was $5.1 million and $6.7 million for the six months ended June 30, 2024 and 2023, respectively. The Company defines gross margin as net product revenues less cost of goods sold divided by net product revenues. Our gross margins increased in the three and six months ended June 30, 2024, compared to the comparable periods in 2023, due to a favorable gross profit mix from lower vial volumes from our international regions. Research and Development Research and development expenses were $12.3 million for the quarter ended June 30, 2024, and relatively flat compared to $12.1 million for the quarter ended June 30, 2023. For the six months ended June 30, 2024 and 2023, research and development expenses were relatively flat at $25.6 million and $25.5 million, respectively. Selling, General, and Administration Selling, general, and administrative expenses were $17.2 million for the three months ended June 30, 2024, which was a $5.9 million increase compared to $11.3 million for the three months ended June 30, 2023. The increase was primarily attributable to a net impact of $3.6 million related to the Company's settlement of a shareholder class-action lawsuit, which is the net impact of the Company's $19.7 million accrued legal settlement, less the corresponding insurance recovery of $16.1 million and an additional legal settlement of $0.2 million in the three months ended June 30, 2024. For the six months ended June 30, 2024, selling, general, and administrative expenses were $28.7 million, an increase of $5.2 million for the six months ended June 30, 2023. The increase was primarily attributable to a net impact of $3.8 million related to the Company's two legal settlements, as noted above. Interest and Other Income Interest and other income were $0.6 million for the three months ended June 30, 2024, as compared to $1.1 million for the three months ended June 30, 2023. The decrease of $0.5 million was primarily due to a $0.2 million gain from repayment of a secured promissory note in the three months ended June 30, 2023, and a $0.2 million increase in foreign currency transaction losses. The Company did not have the repayment of a secured promissory note in the three months ended June 30, 2024. For the six months ended June 30, 2024 and 2023, the interest and other income was $1.1 million and $2.2 million, respectively. The decrease of $1.1 million was primarily due to a $0.8 million increase in foreign currency transaction losses related to the remeasurement of foreign currency denominated assets and liabilities. Net Loss Y-mAbs reported a net loss for the three months ended June 30, 2024, of $9.2 million, or ($0.21) per basic and diluted share, compared to net loss of $6.3 million, or ($0.14) per basic and diluted share, for the three months ended June 30, 2023. For the six months ended June 30, 2024, the Company reported a net loss of $15.9 million, or ($0.36) per basic and diluted share, as compared to net loss of $12.7 million, or ($0.29) per basic and diluted share, for the six months ended June 30, 2023. The increase in net loss for the three and six months ended June 30, 2024 was primarily driven by the net $3.8 million in charges related to the Company's two legal settlements, as described above. Cash and Cash Equivalents As of June 30, 2024, Y-mAbs had approximately $77.8 million in cash and cash equivalents which, together with anticipated DANYELZA product revenues, is expected to support operations as currently planned into 2027. This estimate reflects the Company's current business plan that is supported by assumptions that may prove to be inaccurate. Cash utilized in the first half year of 2024 was $0.8 million, which was favorable to internal company forecasts. 2024 Financial Guidance Management updates its full year 2024 guidance: Anticipated Total Net Revenues now expected to be between $87 million and $95 million; Anticipated Operating Expenses expected to remain between $115 million and $120 million; Anticipated Total Annual Cash Burn expected to remain between $15 million and $20 million; and Cash and Cash Equivalents anticipated to continue to support operations as currently planned into 2027.
