“We remain confident in the potential best-in-class profiles of our programs targeting BTLA and PD-1 co-inhibitory receptors to drive differentiated results as we approach multiple clinical catalysts and value drivers for Anaptys, including top-line Phase 2b data in AD for ANB032, our BTLA agonist, in December. We’ve also completed enrollment for the Phase 2b trial of rosnilimab, our PD-1 agonist, in RA and are narrowing our guidance for top-line data to February 2025,” said Daniel Faga, president and chief executive officer of Anaptys. “Additionally, enrollment in healthy volunteers has commenced for the Phase 1 trial for ANB033, our anti-CD122 antagonist, and we look forward to disclosing the Phase 1b indication in 2025. Looking to the end of the year, we are on track to have four programs in clinical development.”

Cash Runway
•Cash and investments of $458.0 million as of September 30, 2024 and reiterating cash runway through year-end 2026


Third Quarter Financial Results
•Cash, cash equivalents and investments totaled $458.0 million as of September 30, 2024, compared to $417.9 million as of December 31, 2023, for an increase of $40.1 million due primarily to the $100.0 million underwritten registered direct offering completed in Q3 and $50.0 million received from the Sagard royalty monetization in Q2 offset by operating activities.
•Collaboration revenue was $30.0 million and $48.2 million for the three and nine months ended September 30, 2024, compared to $3.3 million and $8.2 million for the three and nine months ended September 30, 2023. The increase in non-cash revenue is due to a $15.0 million commercial milestone earned for annual Jemperli sales exceeding $250.0 million and increased royalties recognized for sales of Jemperli.
•Research and development expenses were $42.2 million and $121.3 million for the three and nine months ended September 30, 2024, compared to $30.9 million and $98.8 million for the three and nine months ended September 30, 2023. The increase was due primarily to development costs for rosnilimab, ANB032, ANB033 and ANB101 offset by a decrease in development costs for imsidolimab. The R&D non-cash, stock-based compensation expense was $4.0 million and $10.9 million for the three and nine months ended September 30, 2024, as compared to $2.2 million and $7.7 million in the same period in 2023.
•General and administrative expenses were $10.6 million and $32.2 million for the three and nine months ended September 30, 2024, compared to $10.2 million and $31.7 million for the three and nine months ended September 30, 2023. The G&A non-cash, stock-based compensation expense was $4.2 million and $14.9 million for the three and nine months ended September 30, 2024, as compared to $5.6 million and $17.4 million in the same period in 2023.
•Net loss was $32.9 million and $123.4 million for the three and nine months ended September 30, 2024, or a net loss per share of $1.14 and $4.46, compared to a net loss of $37.3 million and $121.4 million for the three and nine months ended September 30, 2023, or a net loss per share of $1.41 and $4.49.
