"Our team has made great progress advancing OP-1250 through the dose escalation portion of our ongoing Phase 1/2 clinical trial and we look forward to presenting interim pharmacokinetic, safety, tolerability and initial efficacy data at the San Antonio Breast Cancer Symposium in December," said Sean P. Bohen, M.D., Ph.D., President and Chief Executive Officer of Olema Oncology. "We are encouraged by the emerging clinical profile of OP-1250 and plan to initiate Phase 2 monotherapy expansion as well as the first planned Phase 1b combination trial with a CDK4/6 inhibitor in the first quarter of 2022."

"OP-1250 has the potential to be a differentiated, best-in-class complete estrogen receptor (ER) antagonist (CERAN) that we believe could become the backbone endocrine therapy of choice for ER+ breast cancer. As we enroll more patients, we look forward to generating additional clinical data in support of OP-1250’s use both as monotherapy and in combination with other approved breast cancer treatments," continued Dr. Bohen.

Recent Corporate Highlights

●Completed dose escalation in the ongoing Phase 1/2 study of OP-1250 in patients with metastatic, ER+ / HER2- breast cancer.
●Selected the OP-1250 starting dose and initiated preparations for the first planned combination study with a CDK4/6 inhibitor.
●Presented new nonclinical data on OP-1250 at the 1st JCA-AACR Precision Cancer Medicine International Conference held virtually from September 10-12, 2021 (U.S.)

and September 11-12, 2021 (Japan). The poster presentation reviewed a series of nonclinical assessments Olema conducted on a panel of antiestrogens with known chemical structures to evaluate their ability to inhibit ER activity, block breast cancer proliferation and degrade ER receptors.
●Presented a Trials-in-Progress poster at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper), held virtually from October 7-10, 2021. The poster reviewed the design of Olema’s ongoing Phase 1/2 open-label, first-in-human, multicenter, dose-escalation and dose-expansion study evaluating OP-1250 monotherapy in adult subjects with recurrent, locally advanced or metastatic ER+ / HER2- breast cancer (NCT04505826).
●Expanded Olema’s operational footprint with the opening of new office space in Cambridge, Massachusetts.
Anticipated Milestones

●Present interim Phase 1 monotherapy dose escalation data at the 2021 San Antonio Breast Cancer Symposium.
●Initiate dose expansion by year-end with up to two doses. Each cohort will enroll approximately 15 patients with measurable disease, and findings will help inform the selection of a recommended Phase 2 dose (RP2D).
●Initiate Phase 2 in the first quarter of 2022. Preliminary anti-tumor efficacy will be assessed across three cohorts: patients with measurable disease (N=50), patients with non-measurable disease (N=15) and patients with CNS metastasis (N=15).
●Initiate the first Phase 1b clinical trial of OP-1250 in combination with a CDK4/6 inhibitor in the first quarter of 2022.
Financial Highlights

●Cash, cash equivalents and marketable securities as of September 30, 2021 were $306.0 million. Olema anticipates that this balance of cash will be sufficient to fund operations through the end of 2023.
● Net loss for the quarter ended September 30, 2021 was $17.7 million, compared to $7.8 million for the same period of the prior year.
●Research and development (R&D) expenses were $12.5 million for the quarter ended September 30, 2021, compared to $4.7 million for the same period of the prior year. The increase in R&D expenses was primarily related to the advancement of the ongoing Phase 1/2 clinical trial of OP-1250, increase in nonclinical development activities, higher personnel-related expenses and higher non-cash stock-based compensation expenses.

●General and administrative (G&A) expenses were $5.2 million for the quarter ended September 30, 2021, compared to $3.2 million for the same period of the prior year. The increase in G&A expenses was primarily related to an increase in personnel, public company-related expenses, other corporate costs and higher non-cash stock-based compensation expenses.
