SAN CARLOS, Calif., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Iovance Biotherapeutics, Inc. (NASDAQ: IOVA), a commercial biotechnology company focused on innovating, developing, and delivering novel polyclonal tumor infiltrating lymphocyte (TIL) therapies for patients with cancer, today reported second quarter and first half 2025 financial results and corporate updates.

Frederick Vogt, Ph.D., J.D., Interim President and Chief Executive Officer of Iovance, stated, “In the first half of 2025, we continued to drive U.S. adoption for Amtagvi in advanced melanoma, surpassing more than 100 patients treated within a single quarter. Growth for Amtagvi and Proleukin will continue in the second half of 2025 as existing ATC growth continues and large community practices begin treating patients. We expect our first ex-U.S. regulatory approval imminently and remain on track to provide updates on our clinical programs.”

Launch Expansion into New MarketsAmtagvi has the opportunity to address more than 30,000 patients globally with previously treated advanced melanoma.1Iovance is gaining momentum to address adult patients with previously treated advanced melanoma in new markets.

Net loss for the second quarter of 2025 was $111.7 million, or $0.33 per share, compared to a net loss of $97.1 million, or $0.34 per share, for the second quarter of 2024. Net loss for the first half of 2025 was $227.8 million, or $0.69 per share, compared to a net loss of $210.1 million, or $0.76 per share, for the first half of 2024.

Revenue consists of product revenue from Amtagvi and Proleukin. Revenue was $60.0 million for the second quarter of 2025, a 22% increase from $49.3 million in the first quarter of 2025 and a 93% increase over revenue of $31.1 million in the second quarter of 2024. Product revenue was $54.1 million for Amtagvi and $5.9 million for Proleukin in the second quarter of 2025 compared to $12.8 million for Amtagvi and $18.3 million for Proleukin in the second quarter of 2024.

Revenue was $109.3 million for the first half of 2025, an increase of 243% over revenue of $31.8 million in the prior year six-month period. Product revenue from Amtagvi and Proleukin was $97.7 million and $11.6 million, respectively, in the first half of 2025 compared to $12.8 million and $19.0 million, respectively, in the first half of 2024.

The increase in revenue in the second quarter and first half 2025 over the prior year periods was primarily attributable to the U.S. launch and product revenue growth from Amtagvi.

Cost of sales includes inventory, overhead and related cash and non-cash expenses that are directly associated with sales of Amtagvi and Proleukin, as well as manufacturing costs for Amtagvi.

Cost of sales was $56.7 million for the second quarter 2025, including $19.0 million for period costs associated with patient drop off and manufacturing success rates, $5.9 million for non-cash amortization expense for intangible assets and fair value mark up of inventory, $2.1 million for non-cash stock-based compensation, and $1.2 million in royalties payable on product sales. Cost of sales was $31.4 million in the second quarter of 2024. Cost of sales was $106.4 million for the first half of 2025 compared to $38.6 million in the first half of 2024.

The increase in cost of sales in the second quarter and first half of 2025 over the prior year periods was associated with the initiation and growth of product sales, certain costs associated with patient drop-off and manufacturing success rates, and related cash and non-cash expenses tied to the U.S. launch of Amtagvi that began during the first quarter of 2024.

Research and development expenses were $79.4 million for the second quarter of 2025, an increase of 28% compared to $62.1 million for the second quarter of 2024. Research and development expenses were $156.2 million for the first half of 2025, an increase of 10% compared to $141.9 million for the first half of 2024.

The increases in research and development expenses in the second quarter and first half of 2025 over the prior year periods were primarily attributable to higher headcount and related costs, offset by reductions in stock-based compensation, and clinical trial costs resulting from continued enrollment in existing trials and the resumption of the LUN-202 study. The increases for the first half of 2025 were offset by the transition of Amtagvi to commercial manufacturing.

Selling, general and administrative expenses were $37.7 million for the second quarter of 2025, a decrease of 5% compared to $39.6 million for the second quarter of 2024. The decrease in selling, general and administrative expenses in the second quarter of 2025 compared to the prior year period was primarily attributable to a decrease in stock-based compensation, partially offset by increases in headcount and related costs to support the growth in the overall business and related corporate infrastructure and costs related to the marketing and advertising of Amtagvi.

Selling, general and administrative expenses were $81.6 million for the first half of 2025, an increase of 15% compared to $71.0 million for the first half of 2024. The increase in selling, general and administrative expenses in the first half of 2025 compared to the prior year period was primarily attributable to increases in headcount and related costs, offset by reductions in stock-based compensation, to support the growth in the overall business and related corporate infrastructure, as well as costs incurred to support the distribution and commercialization of Amtagvi and Proleukin.
