"We made substantial progress advancing our innovative, synthetic lethality-based pipeline across multiple programs in 2022, including entering into a worldwide collaboration agreement with Roche to develop camonsertib, receiving Fast Track designation from the FDA for our first-in-class PKMYT1 inhibitor RP-6306, and advancing our preclinical programs," said Lloyd M. Segal, President and Chief Executive Officer of Repare." We expect 2023 to be another productive year for Repare across the portfolio, with early clinical readouts for both camonsertib and RP-6306 in the first half of 2023. In addition, we are poised to expand our pipeline leveraging our proprietary SNIPRx platform, and look forward to sharing more information on our third clinical program this summer."

2022 Highlights and 2023 Outlook:

•
Advancing camonsertib, a potent and selective oral small molecule inhibitor of ATR (Ataxia-Telangiectasia and Rad3-related protein kinase) for the treatment of tumors with specific synthetic lethal genomic alterations in partnership with Roche.
o
Initial data from the Phase 1/2 trials evaluating camonsertib in combination with three poly (ADP-ribose) polymerase (PARP) inhibitors is expected to be presented in the first half of 2023 at a major medical meeting.
o
The Company expects to report initial data from the Phase 1/2 TRESR trial evaluating camonsertib in combination with gemcitabine in the summer or fall of 2023.
•
Evaluating RP-6306, a first-in-class, oral PKMYT1 inhibitor as a monotherapy and in combinations in multiple early clinical studies.
o
The Company expects to report initial Phase 1 clinical data for RP-6306 as a monotherapy for the treatment of molecularly selected advanced solid tumors (MYTHIC) in the first half of 2023. The Company expects to report initial Phase 1 clinical data for RP-6306 as a combination therapy for the treatment of molecularly selected advanced solid tumors in the fourth quarter of 2023.
o
In the fourth quarter of 2022, the U.S. Food and Drug Administration (FDA) granted Fast Track designation (FTD) to RP-6306 in combination with gemcitabine for the treatment of adult patients with CCNE1 amplified, or FBXW7 or PPP2R1A mutated platinum resistant ovarian cancer. FTD is intended to facilitate the development and expedite the review of drugs to treat serious conditions and fulfill an unmet medical need, enabling drugs to reach patients earlier.
o
Based on promising preclinical data released at the 34th EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Symposium in October 2022, Repare is working with clinical investigators to initiate clinical testing, as part of an investigator-sponsored trial (IST), of a fourth new RP-6306 combination with carboplatin, with first patient dosing expected in the first half of 2023.

o
In the fourth quarter of 2022, Repare entered into an agreement with Canadian Cancer Trials Group (CCTG) for a planned, basket Phase 2 IST to evaluate RP-6306 in patients with selected, advanced cancers receiving standard agents. A sub-study under the master clinical trial protocol will evaluate RP-6306 in combination with gemcitabine in patients with CD4/6i-resistant ER+/HER2- metastatic breast cancer.
•
Advancing preclinical programs into clinical development.
o
Repare expects to initiate IND-enabling studies in the first half of 2023 for a small molecule against an undisclosed target with potential to enter the clinic in late 2023 or early 2024, which represents an acceleration from the Company’s prior expectations for this program.
o
Repare is pursuing development of an inhibitor of polymerase theta (Polθ) in collaboration with Ono Pharmaceutical Company Ltd (Ono) in Japan, South Korea, Taiwan, Hong Kong, Macau and ASEAN countries, excluding mainland China. Repare retains all rights to develop and commercialize the products outside the Ono territory. In 2022, the Company selected a proposed inhibitor of Polθ, which it designated as RP-2119. In February 2023, based on its review of ongoing preclinical studies, Repare elected to prioritize other Polθ inhibiting compounds in its preclinical development portfolio, which it believes have a higher probability for clinical impact relative to RP-2119. The Company is now guiding toward clinical entry for a Polθ inhibitor in 2024.
o
In January 2023, Repare received an approximate $1.5 million (¥200 million) milestone payment from Ono. The payment reflected the achievement of a research milestone under the Company’s research services, license and collaboration agreement with Ono (Ono Agreement).
o
Also in January 2023, Repare and Ono amended the Ono Agreement to further extend the research term until July 31, 2023. Previously, Repare had entered into an amendment with Ono in October 2021 to extend the research term by one year at no additional cost to Repare.
Fourth Quarter and Full Year 2022 Financial Results:

•
Cash and cash equivalents and marketable securities: Cash and cash equivalents and marketable securities as of December 31, 2022 were $343.9 million, which Repare believes will be sufficient to fund its planned operations into 2026.
•
Revenue from collaboration agreements: Revenue from collaboration agreements were $18.2 million and $131.8 million for the three- and twelve-month periods ended December 31, 2022, respectively, as compared to $6.9 million and $7.6 million for the three- and twelve-month periods ended December 31, 2021, due to revenue recognized from our collaboration and license agreement with Roche.
•
Research and development expenses, net of tax credits (Net R&D): Net R&D expenses were $29.9 million and $119.1 million for the three- and twelve-month periods ended December 31, 2022, respectively, as compared to $28.0 million and $90.0 million for the three- and twelve-month periods ended December 31, 2021 due to an increase in development activities related to the advancement of the RP-6306 program and preclinical activities related to pipeline programs; an increase of personnel-related costs, including share-based compensation, for increased headcount in support of discovery and development activities; and other research and development costs. Camonsertib costs were similar on a year over year basis and decreased quarter over quarter following the transfer of CMC related activities to Roche pursuant to the collaboration agreement.

•
General and administrative (G&A) expenses: G&A expenses were $7.9 million and $32.6 million for the three- and twelve-month periods ended December 31, 2022, respectively, as compared to $7.6 million and $26.2 million for the three- and twelve-month periods ended December 31, 2021. The increase in G&A expenses for the three- and twelve-month periods were primarily due to higher personnel related costs, including share-based compensation; an increase in professional fees associated with the Roche collaboration agreement and the establishment of our at-the-market (ATM) offering, as well as timing of audit and SOX compliance efforts, partially offset by a decrease in our D&O insurance premium.
•
Net loss: Net loss was $31.7 million, or $0.75 per share, and $29.0 million, or $0.69 per share, for the three- and twelve-month periods ended December 31, 2022, respectively, and $28.3 million, or $0.70 per share and $106.9 million, or $2.83 per share, for the three- and twelve-month periods ended December 31, 2021, respectively.
About Repare Therapeutics’ SNIPRx Platform

Repare’s SNIPRx platform is a genome-wide CRISPR-based screening approach that utilizes proprietary isogenic cell lines to identify novel and known synthetic lethal gene pairs and the corresponding patients who are most likely to benefit from the Company’s therapies based on the genetic profile of their tumors. Repare’s platform enables the development of precision therapeutics in patients whose tumors contain one or more genomic alterations identified by SNIPRx screening, in order to selectively target those tumors in patients most likely to achieve clinical benefit from resulting product candidates.
