Second Quarter 2025 Financial Results
Cash, cash equivalents, and marketable securities of $361.9 million as of June 30, 2025.
Net loss for the quarter ended June 30, 2025 was $43.8 million, as compared to $30.4 million for the quarter ended June 30, 2024. The increase in net loss for the second quarter was related to a one-time milestone payment of $10 million made to Aurigene in conjunction with our KAT6 clinical development program as well as increased spending on research and development activities as a result of the ongoing late-stage clinical trials for palazestrant and the advancement of OP-3136, partially offset by higher interest income earned from marketable securities.
GAAP research and development (R&D) expenses were $43.9 million for the quarter ended June 30, 2025, as compared to $29.1 million for the quarter ended June 30, 2024. The increase in R&D expenses was primarily related to a one-time milestone payment of $10 million made to Aurigene as well as increased spending on clinical development-related activities as Olema continues to advance palazestrant through late-stage clinical trials, and the advancement of OP-3136.
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. Non-GAAP R&D expenses were $24.9 million for the quarter ended June 30, 2024, which excluded $4.2 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 $4.0 million for the quarter ended June 30, 2025, as compared to $4.4 million for the quarter ended June 30, 2024. The decrease in G&A expenses was primarily due to a decrease in non-cash stock-based compensation expense of $0.5 million.
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. Non-GAAP G&A expenses were $2.9 million for the quarter ended June 30, 2024, excluding $1.5 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.
About Olema Oncology
Olema Oncology is a clinical-stage biopharmaceutical company committed to transforming the standard of care and improving outcomes for patients living with breast cancer and beyond. Olema is advancing a pipeline of novel therapies by leveraging our deep understanding of endocrine-driven cancers, nuclear receptors, and mechanisms of acquired resistance. Our lead product candidate, palazestrant (OP-1250), is a proprietary, orally available complete estrogen receptor (ER) antagonist (CERAN) and a selective ER degrader (SERD), currently in a Phase 3 clinical trial called OPERA-01. In addition, Olema is developing OP-3136, a potent lysine acetyltransferase 6 (KAT6) inhibitor, now in a Phase 1 clinical study. Olema is headquartered in San Francisco and has operations in Cambridge, Massachusetts. For more information, please visit www.olema.com.
About Palazestrant (OP-1250)
Palazestrant (OP-1250) is a novel, orally available small molecule with dual activity as both a complete estrogen receptor (ER) antagonist (CERAN) and selective ER degrader (SERD). It is currently being investigated in patients with recurrent, locally advanced or metastatic ER-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer. In clinical studies, palazestrant completely blocks ER-driven transcriptional activity in both wild-type and mutant forms of metastatic ER+ breast cancer and has demonstrated anti-tumor efficacy along with attractive pharmacokinetics and exposure, favorable tolerability, central nervous system penetration, and combinability with cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. Palazestrant has been granted U.S. Food and Drug Administration (FDA) Fast Track designation for the treatment of ER+/HER2- metastatic breast cancer that has progressed following one or more lines of endocrine therapy with at least one line given in combination with a CDK4/6 inhibitor. It is being evaluated as a single agent in the ongoing pivotal Phase 3 clinical trial, OPERA-01 and is anticipated to be evaluated in combination with ribociclib in the planned pivotal Phase 3 clinical trial, OPERA-02. Learn more at www.opera01study.com. Palazestrant has also been evaluated in multiple Phase 1/2 studies in combination with ribociclib, palbociclib, alpelisib, and everolimus.
About OP-3136
OP-3136 is a novel, orally available small molecule that potently and selectively inhibits lysine acetyltransferase 6 (KAT6), an epigenetic target that is dysregulated in breast and other cancers. In preclinical studies, OP-3136 has demonstrated significant anti-proliferative activity in ER+ breast cancer models and is combinable and synergistic with endocrine therapies including palazestrant and cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. The Investigational New Drug (IND) application for OP-3136 was cleared by the U.S. Food and Drug Administration (FDA) in December 2024 and patients are currently enrolling in the Phase 1 clinical study.
Non-GAAP Financial Information
The results presented in this press release include both GAAP information and non-GAAP information. As used in this release, non-GAAP R&D expense is defined by Olema as GAAP R&D expense excluding stock-based compensation expense, and non-GAAP G&A expense is defined by Olema as GAAP G&A expense excluding stock-based compensation expense. We use these non-GAAP financial measures to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.
