SAN FRANCISCO, Nov. 12, 2024 (GLOBE NEWSWIRE) -- Olema Pharmaceuticals, Inc. (“Olema”, “Olema Oncology”, Nasdaq: OLMA), a clinical-stage biopharmaceutical company focused on the discovery, development, and commercialization of targeted therapies for breast cancer and beyond, today reported financial results for the third quarter ended September 30, 2024, and provided a corporate update.

“We look forward to presenting updated data from our ongoing Phase 2 clinical study of palazestrant in combination with ribociclib in frontline metastatic breast cancer patients at SABCS in December. The OPERA-01 Phase 3 clinical trial of palazestrant as a monotherapy in second/third-line patients continues to advance and we remain on track for top-line readout in 2026,” said Sean P. Bohen, M.D., Ph.D., President and Chief Executive Officer of Olema Oncology. “At ENA 2024, we presented three new, robust preclinical data sets. Palazestrant demonstrated combinability and enhanced tumor suppression with both everolimus and capivasertib. OP-3136, our potent and selective KAT6 inhibitor, demonstrated robust anti-tumor activity as a single agent, as well as synergy and enhanced anti-tumor activity in combination with palazestrant. These data reinforce our belief in the potential of OP-3136 as an exciting new therapy for breast and other cancers, and we remain on track to submit the IND application before year end.”

Recent Progress

• Continued enrollment of patients in OPERA-01, the pivotal Phase 3 clinical trial of palazestrant as a monotherapy in second/third-line ER+/HER2- metastatic breast cancer.
• Presented preclinical data for OP-3136 and palazestrant at the 36^th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics (ENA 2024) in Barcelona, Spain.
• Initiated Phase 1b/2 clinical study of palazestrant in combination with everolimus.
• Successfully completed Investigational New Drug (IND)-enabling studies for OP-3136.

Anticipated Upcoming Milestones

• Present updated Phase 2 data showing palazestrant in combination with ribociclib at the San Antonio Breast Cancer Symposium (SABCS) in December 2024.
• Submit the IND application for OP-3136 to the U.S. Food and Drug Administration (FDA) before year-end; initiate the Phase 1 clinical study for OP-3136 in early 2025.

Third Quarter 2024 Financial Results

Cash, cash equivalents, and marketable securities as of September 30, 2024, were $214.8 million.

Net loss for the quarter ended September 30, 2024, was $34.6 million, as compared to $21.5 million for the quarter ended September 30, 2023. The increase in net loss for the third quarter was primarily related to increased spending on clinical development and research activities as a result of late-stage clinical trials for palazestrant and the advancement of our KAT6 inhibitor program, as well as general and administrative (G&A) activities. The increase was partially offset by higher interest income earned from marketable securities.

GAAP research and development (R&D) expenses were $33.2 million for the quarter ended September 30, 2024, as compared to $19.5 million for the quarter ended September 30, 2023. The increase in R&D expenses was primarily related to increased spending on clinical operations and development-related activities as we continue to advance palazestrant through late-stage clinical trials, research-related activities associated with the advancement of our KAT6 inhibitor program, and personnel related costs, including an increase in non-cash stock-based compensation expense of $1.5 million.

Non-GAAP R&D expenses were $28.9 million for the quarter ended September 30, 2024, which excluded $4.3 million non-cash stock-based compensation expense. Non-GAAP R&D expenses were $16.7 million for the quarter ended September 30, 2023, excluding $2.8 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 $4.4 million for the quarter ended September 30, 2024, as compared to $3.9 million for the quarter ended September 30, 2023. The increase in G&A expenses was primarily due to increased spending on corporate-related costs and an increase in non-cash stock-based compensation expense of less than $0.1 million.

Non-GAAP G&A expenses were $3.0 million for the quarter ended September 30, 2024, excluding $1.3 million non-cash stock-based compensation expense. Non-GAAP G&A expenses were $2.6 million for the quarter ended September 30, 2023, excluding $1.3 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 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, CNS penetration, and combinability with 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 both as a single agent in an ongoing Phase 3 clinical trial, OPERA-01, and in Phase 1/2 combination studies with CDK4/6 inhibitors (palbociclib and ribociclib), a PI3Ka inhibitor (alpelisib), and an mTOR inhibitor (everolimus).

About OP-3136

OP-3136 is a novel, orally available small molecule that potently and selectively inhibits 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 CDK4/6 inhibitors. Olema has successfully completed IND-enabling studies in support of a potential Investigational New Drug (IND) application with the FDA and expects to initiate Phase 1 clinical trials for OP-3136 in early 2025.

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.
