"Our commitment to transforming the metastatic breast cancer treatment paradigm remains resolute as we continue to advance palazestrant as a potentially differentiated endocrine therapy across multiple regimens. Importantly, enrollment in our pivotal OPERA-01 Phase 3 trial is complete and we now expect to report top-line data in the first quarter of 2027," said Sean P. Bohen, M.D., Ph.D., President and Chief Executive Officer of Olema Oncology. "Beyond palazestrant, we made significant progress with OP-3136, our novel KAT6 inhibitor. The initial monotherapy Phase 1 data, presented at ASCO (Free ASCO Whitepaper), demonstrated that OP-3136 was well-tolerated and showed evidence of anti-tumor activity across multiple dose levels and various tumor types. These data, taken together with our first clinical collaboration for OP-3136, established with Bayer to evaluate OP-3136 in combination with darolutamide in metastatic castration-resistant prostate cancer, reinforce our confidence in its potential as a best-in-class, differentiated option for patients with advanced solid tumors."

Bohen continued, "Supported by a strong balance sheet, we are intently focused on execution in the second half of the year as we ramp preparations for our first potential commercial launch of palazestrant as a monotherapy, work to establish palazestrant as a potential combination agent of choice in breast cancer, and continue our transformation into a fully integrated oncology company."

Recent Progress

Second Quarter 2026 Financial Results
Cash, cash equivalents, and marketable securities as of June 30, 2026, were $461.1 million.

Net loss for the quarter ended June 30, 2026 was $63.2 million, as compared to $43.8 million for the quarter ended June 30, 2025. The increase in net loss for the second quarter was related to higher spending on clinical development and research and corporate-related activities related to late-stage clinical trials for palazestrant and the advancement of OP-3136.

GAAP research and development (R&D) expenses were $57.8 million for the quarter ended June 30, 2026, as compared to $43.9 million for the quarter ended June 30, 2025. The increase in R&D expenses was primarily related to increased spending on clinical development-related activities as we continue to advance palazestrant through late-stage clinical trials and OP-3136 in early-stage clinical studies, and increased personnel-related costs to support expanding development activities, including an increase in non-cash stock-based compensation expense of $5.2 million, mainly due to higher grant prices in 2026 and higher headcount. These increases were partially offset by the $10.0 million milestone expense related to the Aurigene agreement that was recognized in the same period in 2025.

Non-GAAP R&D expenses were $48.9 million for the quarter ended June 30, 2026, excluding $8.9 million non-cash stock-based compensation expense. Non-GAAP R&D expenses were $40.2 million for the quarter ended June 30, 2025, excluding $3.7 million non-cash stock-based compensation expense. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release.

GAAP G&A expenses were $9.4 million for the quarter ended June 30, 2026, as compared to $4.0 million for the quarter ended June 30, 2025. The increase in G&A expenses was primarily due to higher corporate-related costs that reflect continued investment in personnel and corporate infrastructure to support our expanding late-stage clinical development activities and anticipated future commercial operations, including an increase in non-cash stock-based compensation expense of $3.0 million, mainly due to higher grant prices in 2026, and an increase in professional fees of $1.8 million.

Non-GAAP G&A expenses were $5.4 million for the quarter ended June 30, 2026, excluding $4.0 million non-cash stock-based compensation expense. Non-GAAP G&A expenses were $3.0 million for the quarter ended June 30, 2025, excluding $1.0 million non-cash stock-based compensation expense. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release.
