RAPT RAPT Therapeutics Inc

RAPT Therapeutics, Inc. (Nasdaq: RAPT) (“RAPT” or the “Company”) is a clinical-stage immunology-based biopharmaceutical company focused on discovering, developing and commercializing novel therapies for patients living with inflammatory and immunological diseases, today reported financial results for the fourth quarter and year ended December 31, 2024.

“Our focus for 2025 will be on advancing development of RPT904, a novel, potential best-in-class option to treat the large and underserved population of patients suffering from food allergy and chronic spontaneous urticaria,” said Brian Wong, President and CEO of RAPT. “We believe RPT904 can be a differentiated product to treat these diseases by targeting IgE, an approach validated by omalizumab. We expect to initiate a Phase 2b clinical trial for RPT904 in food allergy in the second half of 2025 and await clinical data later this year from our partner Jemincare to guide our development strategy in CSU.”

Financial Results for the Fourth Quarter and Year Ended December 31, 2024

Fourth Quarter Ended December 31, 2024

Net loss for the fourth quarter of 2024 was $53.2 million, compared to $30.9 million for the fourth quarter of 2023.

Research and development expenses for the fourth quarter of 2024 were $46.5 million, compared to $26.8 million for the same period in 2023. The increase in research and development expenses was primarily due to the $35.0 million upfront license fee for RPT904, partially offset by lower development costs related to zelnecirnon, tivumecirnon and early-stage programs, as well as decreased expenses for personnel, professional services, non-cash stock-based compensation and lab supplies.

General and administrative expenses for the fourth quarter of 2024 were $8.0 million, compared to $6.5 million for the same period in 2023. The increase in general and administrative expenses was primarily due to increases in expenses for professional services, non-cash stock-based compensation, personnel and facilities.

In December 2024, the Company entered into a license agreement with Shanghai Jemincare Pharmaceutical Co., Ltd. (“Jemincare”), a company incorporated in the People’s Republic of China, under which the Company obtained exclusive rights to RPT904 throughout the world, excluding mainland China, Hong Kong, Macau and Taiwan. As consideration for those rights, the Company paid a $35.0 million upfront license fee and could pay up to $672.5 million in additional milestone payments, as well as tiered royalty payments (at percentages ranging from high single-digit to low double-digit) on future net sales.

Also in December 2024, the Company sold through a private placement to a select group of accredited investors 100,000,000 shares of common stock at a price of $0.85 per share and pre-funded warrants to purchase 76,452,000 shares of common stock at a purchase price of $0.8499 per pre-funded warrant, resulting in net proceeds of $143.0 million after deducting offering expenses.

Year Ended December 31, 2024

Net loss for the year ended December 31, 2024 was $129.9 million, compared to $116.8 million for the same period in 2023.

Research and development expenses for the year ended December 31, 2024 were $107.2 million, compared to $101.0 million for the same period in 2023. The increase in research and development expenses was primarily due to the $35.0 million upfront license fee for RPT904 and an increase in non-cash stock-based compensation expense, partially offset by lower development costs related to zelnecirnon, tivumecirnon and early-stage programs, as well as decreased expenses for personnel, professional services and lab supplies.

General and administrative expenses for the year ended December 31, 2024 were $28.9 million, compared to $26.1 million for the same period in 2023. The increase in general and administrative expenses was primarily due to increased expenses for non-cash stock-based compensation, consultants, personnel, and facilities, partially offset by decrease in expenses for insurance premiums.

As of December 31, 2024, the Company had cash and cash equivalents and marketable securities of $231.1 million.
