CAMBRIDGE, Mass. & MONTREAL--(BUSINESS WIRE)--Aug. 12, 2021-- Repare Therapeutics Inc. (“Repare” or the “Company”) (Nasdaq: RPTX), a leading clinical-stage precision oncology company enabled by its proprietary synthetic lethality approach to the discovery and development of novel therapeutics, today reported financial results for the second quarter ended June 30, 2021.

“We are pleased to have dosed the first patient in our Phase 1b/2 ATTACC trial of our ATR inhibitor RP-3500 and additional new PARP inhibitor combinations in patients with molecularly selected cancers.” said Lloyd M. Segal, President and Chief Executive Officer of Repare. “We also look forward to disclosing initial results from the monotherapy arm of the Phase 1/2 clinical trial of our ATR inhibitor RP-3500 early in the fourth quarter of 2021.”

Second Quarter 2021 Review and Operational Updates:

• Announced dosing of first patient in Phase 1b/2 ATTACC clinical trial
  • In August 2021, the Company dosed the first patient in its Phase 1b/2 ATTACC clinical trial (NCT04972110) of RP-3500, a potent and selective oral small molecule inhibitor of Ataxia-Telangiectasia and Rad3-related protein kinase, or ATR, and PARP inhibitor combinations in patients with molecularly selected cancers.
  • The primary objectives of the Phase 1b portion of the trial include assessment of safety and tolerability and dose finding to establish a recommended Phase 2 dose (“RP2D”) of RP-3500 in combination with ZEJULA (niraparib) or LYNPARZA (olaparib) in up to 48 patients (24 per combination) with advanced solid tumors harboring specific mutations in DNA damage response.
  • The Phase 2 portion of the trial is designed to include a dose expansion at the RP2D with a primary objective to determine the antitumor activity of RP-3500 in combination with niraparib or olaparib.

• Initial results to be presented from the monotherapy arm of the Phase 1/2 TRESR clinical trial evaluating RP-3500 as a monotherapy and in combination with Pfizer’s PARP inhibitor, talazoparib, in patients with solid tumors
  • In July 2020, the Company began dosing in a Phase 1/2 clinical trial of RP-3500.
  • The Company has activated 12 clinical trial sites across North America and Europe.
  • The Company plans to disclose initial results from the monotherapy arm early in the fourth quarter of 2021.

• Announced dosing of first patient in RP-6306 Phase 1 clinical trial
  • In April 2021, the Company dosed the first patient in its Phase 1 clinical trial of RP-6306.
  • The trial is expected to enroll approximately 60 patients with recurrent tumors characterized by genomic alterations predicted by the Company’s SNIPRx® CRISPR-based platform to be sensitive to RP-6306.
  • The trial objectives include assessment of safety, tolerability, dose, and schedule (including the establishment of a recommended Phase 2 dose).

• Progressed towards first druggable target option exercise in our Bristol Myers Squibb collaboration and license agreement
  • In July and August 2021, the Company received notification with respect to druggable targets from Bristol Myers Squibb, pursuant to the Bristol Meyers Squib collaboration and license agreement. Based on these notifications, we reclassified $6.2 million of non-current deferred revenue to current.

Second Quarter 2021 Financial Results:

• Cash and cash equivalents, restricted cash and marketable securities: Cash and cash equivalents, restricted cash and marketable securities as of June 30, 2021 were $301.0 million.

• Research and development expenses, net of tax credits (Net R&D): Net R&D expenses were $20.2 million and $36.7 million for the three and six-month periods ended June 30, 2021, respectively, as compared to $9.0 million and $17.6 million for the three and six-month periods ended June 30, 2020, respectively. The increase in R&D expenses for the three and nine-month periods were primarily due to increases in development costs related to the Company’s RP-3500 and RP-6306 programs, as well as increases in personnel related expenses, including stock-based compensation.

• General and administrative (G&A) expenses: G&A expenses were $6.7 million and $12.0 million for the three and six-month periods ended June 30, 2021, respectively, as compared to $3.4 million and $5.6 million for the three and six-month periods ended June 30, 2020, respectively. The increase in G&A expenses for the three and six-month periods were due to personnel related costs, including stock-based compensation, and D&O insurance which increased as a result of the Company’s IPO in June 2020.

• Net loss: Net loss was $26.3 million, or $0.71 per share and $47.7 million, or $1.29 per share, in the three and six-month periods ended June 30, 2021, respectively, and $11.8 million, or $2.45 per share and $24.4 million, or $7.56 per share, in the three and six-month periods ended June 30, 2020, 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.
