Rubius Therapeutics Reports Third Quarter 2019 Financial Results and Operational Progress

CAMBRIDGE, Mass., Nov. 14, 2019 (GLOBE NEWSWIRE) — Rubius Therapeutics, Inc. (Nasdaq:RUBY), a clinical-stage biopharmaceutical company that is genetically engineering red blood cells to create an entirely new class of cellular medicines, today reported third quarter 2019 financial results and provided an overview of operational progress.
“Over the last quarter, our team has successfully manufactured RTX-134 for our Phase 1b trial for the treatment of patients with phenylketonuria. Our clinical sites are actively recruiting patients, and we plan to announce when we have treated the first patient. In order for us to share follow up data from the first patients treated in the study, we expect to report initial clinical results during the first quarter of 2020,” said Pablo J. Cagnoni, M.D., chief executive officer of Rubius Therapeutics. “We continue to make good progress with our entire pipeline, having presented preclinical oncology data showcasing the versatility and potential power of the RED PLATFORM^®. We remain on track to file our first oncology Investigational New Drug application for RTX-240 by early 2020.”Recent Highlights and Upcoming Milestones
             
• Over the third quarter, Rubius Therapeutics successfully manufactured RTX-134 for our Phase 1b trial for the treatment patients with phenylketonuria (PKU).
• Rubius has clinical sites actively recruiting patients and plans to announce when the first patient has been treated.
• In order for Rubius to share follow up data from the first patients treated in the study, the Company expects to report initial clinical results during the first quarter of 2020, including:
Preliminary safety;
Longevity of RTX-134 in circulation; and
Proof-of-mechanism as measured by production of trans-cinnamic acid, a metabolite of phenylalanine when degraded by
phenylalanine ammonia lyase, or PAL.• On November 8, 2019, Rubius presented preclinical data at the SITC Annual Meeting, supporting its lead artificial antigen presenting cell program, RTX-321, for the treatment of HPV 16-positive tumors.RTX-321 is an allogeneic artificial antigen presenting cell engineered to express, on the cell surface, an HPV peptide antigen, 4-1BBL and IL-12 to mimic human T cell-APC interactions. RTX-321 is currently in IND-enabling studies.
Proof-of-concept data generated in a B16-F10 melanoma mouse model demonstrated successful engineering of artificial antigen presenting cells against a melanoma tumor-associated antigen, gp100, that significantly expanded antigen-specific T cells and eliminated lung metastases with limited, reversible toxicity.
• On October 29, 2019, Rubius Therapeutics was issued U.S. Patent No. 10,456,421 covering Red Cell Therapeutic™ (RCT) compositions comprising 4-1BBL and their use for the treatment of cancer.  4-1BBL is expressed on the cell surface of each of the Company’s lead oncology product candidates: RTX-240, RTX-224 and RTX-321.
Today, in total, Rubius Therapeutics has nine issued U.S. patents, including five composition of matter patents, 32 patent families and more than 150 pending patent applications worldwide.
• On October 27, 2019, Rubius Therapeutics presented preclinical data at the AACR-NCI-EORTC, demonstrating the ability to engineer RCTs to create loadable artificial antigen presenting cells for personal neoantigens.RTX-aAPCs with peptide-loaded MHC constructs functionally engaged TCRs and achieved robust expansion of primary cytomegalovirus (CMV)-specific T cells in healthy donor PBMCs with prior exposure to CMV.Rubius Therapeutics’ loadable aAPC system has the potential to generate aAPCs containing multiple neoantigens in a single therapeutic.• The Company continued to strengthen its leadership team by appointing Maiken Keson-Brookes as chief legal officer and corporate secretary.                         Third Quarter Financial ResultsNet loss for the third quarter of 2019 was $47.0 million or $0.59 per common share, compared to $26.4 million or $0.42 per common share in the third quarter of 2018.In the third quarter of 2019, Rubius invested $33.5 million in research and development (R&D) related to its novel RED PLATFORM^® and towards expanding and advancing its product pipeline, as compared to $14.4 million in the third quarter of 2018. This year-over-year increase was driven primarily by $8.6 million in incremental R&D program spending in preparation for the Company’s Phase 1b clinical trial for RTX-134 and towards preclinical activities for Rubius’ lead oncology programs, including RTX-240. In addition, $7.8 million in incremental R&D spending was driven by increased R&D headcount, a move into larger facilities and purchasing lab supplies to support Rubius’ goal of delivering four to five INDs across 2019 and 2020. Contract research costs increased by $1.9 million and R&D stock-based compensation also increased by $0.8 million.G&A expenses were $15.0 million during the second quarter of 2019, as compared to $13.2 million for the third quarter of 2018. The higher costs were primarily driven by a $2.1 million increase in personnel and facility costs due to increased headcount in the general and administrative function, as well as increases in professional fees and infrastructure costs to support the Company’s growth.Nine Month Financial ResultsNet loss for the first nine months of 2019 was $119.0 million or $1.52 per common share, compared to $62.0 million or $2.33 per common share in the first nine months of 2018.In the nine months ended September 30, 2019, Rubius invested $81.9 million in R&D related to its novel RED PLATFORM^® and towards expanding and advancing its product pipeline, as compared to $35.2 million in the first nine months of 2018. This year-over-year increase was largely due to an additional $22.4 million in R&D personnel, external research and facilities and lab supplies to support the Company’s pipeline expansion in 2019 and 2020 and $19.8 million in R&D program spending, including preparing for the RTX-134 Phase 1b clinical trial and preclinical activities for Rubius’ lead oncology programs, including RTX-240. R&D stock-based compensation also increased by $4.5 million.G&A expenses were $42.3 million during the first nine months of 2019, as compared to $27.3 million for the same period in 2018. The higher costs were primarily driven by a $7.6 million increase in stock-based compensation and a $7.4 million increase in personnel costs and facility costs due to increased headcount in our general and administrative function, as well as increases in professional fees and infrastructure costs to support the Company’s growth.Cash PositionAs of September 30, 2019, cash, cash equivalents and investments were $324.7 million as compared to $404.1 million as of December 31, 2018, providing Rubius with a cash runway into 2021. During the year, the Company used $81.5 million of cash to fund operations and $27.4 million to fund capital expenditures, including work related to the buildout of Rubius’ manufacturing facility. In addition, during the year, the Company drew down a second tranche of $25.0 million from its $75.0 million loan agreement with Solar Capital in June 2019, which leaves a third tranche of $25.0 million that can be drawn through June 2020, subject to the satisfaction of certain financial covenants.About Rubius TherapeuticsRubius Therapeutics is a clinical-stage biopharmaceutical company developing a new class of medicines called Red Cell Therapeutics™.
