Collaboration revenue was $0 for the three months ended June 30, 2026, compared to $3.2 million for the same period in 2025, and $0 for the six months ended June 30, 2026, compared to $8.6 million for the same period in 2025. All remaining deferred revenue from the upfront and research option-extension payments under the Gilead collaboration was recognized as collaboration revenue during the year ended December 31, 2025 as a result of the truncation of the collaboration agreement which concluded all research activities. Research and development expenses were $37.2 million for the three months ended June 30, 2026, compared to $32.8 million for the same period in 2025, and $70.7 million for the six months ended June 30, 2026, compared to $6 9.2 million for the same period in 2025. The change was primarily due to increased spend related to the advancement of the vopimetostat and TNG456 clinical programs. This increase was partially offset by decreased spend resulting from the impact of our portfolio prioritization efforts. General and administrative expenses were $22.6 million for the three months ended June 30, 2026, compared to $11.3 million for the same period in 2025, and $37.8 million for the six months ended June 30, 2026, compared to $22.8 million for the same period in 2025. The increase was primarily due to increased spend on personnel- related costs, including share-based compensation expense. Net loss for the three months ended June 30, 2026 was $55.3 million, or $0.37 per share, compared to a net loss of $38.9 million, or $0.35 per share, in the same period in 2025. Net loss for the six months ended June 30, 202 was $100.9 million, or $0.6 8 per share, compared to a net loss of $78.7 million, or $0.71 per share, in the same period in 2025.
