Company Provides Update on Phase 1 Clinical Trial of RTX-321 in Advanced Human Papilloma Virus (HPV) 16-Positive Cancers
CAMBRIDGE, Mass., May 10, 2022 (GLOBE NEWSWIRE) -- Rubius Therapeutics, Inc. (Nasdaq: RUBY), a clinical-stage biopharmaceutical company that is biologically engineering red blood cells to create an entirely new class of cellular medicines called Red Cell Therapeutics™ for the treatment of cancer and autoimmune diseases, today reported first quarter 2022 financial results and provided a business update.
“With the updated results showing single-agent activity and encouraging tolerability of monotherapy RTX-240 in patients whose disease progressed on PD-(L)1 inhibitors, we believe we have the opportunity to develop RTX-240 as a combination therapy with immune checkpoint inhibitors in earlier lines of therapy, where the greatest need exists for patients with NSCLC and RCC,” said Pablo J. Cagnoni, M.D., president and chief executive officer. “We have expanded our Phase 1 arm of RTX-240 in combination with pembrolizumab to focus on less heavily pretreated patients with NSCLC and RCC. We plan to report initial clinical results from the combination arm in advanced solid tumors and initial data from the NSCLC and RCC patients in the second half of 2022.”
Dr. Cagnoni continued, “We believe RTX-321 has shown promising pharmacodynamic effects with dramatic expansion of CD4+ T cells, which is one of the key cells involved in the mechanism by which IL-12 stimulates a broad anti-tumor response. Importantly, we continue to see no dose-limiting toxicities and no treatment-related adverse events, giving us confidence that we may be able to safely exploit IL-12’s potent antitumor activity with RTX-224, our second broad immune agonism program. RTX-224 expresses higher copy numbers of IL-12 on the cell surface than does RTX-321. Given the additional investment required to dose escalate and the eventual need for a companion diagnostic for patient selection for RTX-321, we are focusing our resources at this time on advancing our broad agonism approach with RTX-240 and RTX-224.”
Broad Immune Stimulation
RTX-240 is an allogeneic, off-the-shelf cellular therapy product candidate that is engineered to simultaneously present hundreds of thousands of copies of the costimulatory molecule 4-1BB ligand (4-1BBL) and IL-15TP (trans-presentation of IL-15 on IL-15Ra) in their native forms. RTX-240 is designed to broadly stimulate the immune system by activating and expanding both NK and CD8+ memory T cells to generate an anti-tumor response.

Three dose cohorts were completed (n=9) with one patient with anal squamous cell carcinoma with SD ongoing at 16 weeks at the highest dose cohort to date of 1e10 administered every three weeks. Prior to enrollment, the patient experienced disease progression on anti-PD-1 therapy. RTX-321 was generally well tolerated with no DLTs or Grade 3/4 treatment-related AE’s. Consistent with the combined mechanism of action of IL-12 and 4-1BBL, increases in activated CD4+ T cells, activated CD8+ T cells and activated NK cells were observed at the higher dose levels.
Anticipated 2022 Catalysts and Operational Objectives
To evaluate the full potential of RTX-240, Rubius’ other oncology programs and the RED PLATFORM, Rubius plans to execute several critical milestones within the next 12 months and has sufficient cash runway into the second half of 2023:
First Quarter 2022 Financial Results
Net loss for the first quarter of 2022 was $52.4 million or $0.58 per common share, compared to $42.3 million or $0.51 per common share in the first quarter of 2021.
In the first quarter of 2022, Rubius invested $38.3 million in research and development (R&D) related to its novel RED PLATFORM® and towards expanding and advancing its product pipeline, compared to $27.7 million in the first quarter of 2021. This year-over-year increase was principally due to a $5.3 million increase in costs related to our lead cancer programs, RTX-240, RTX-321 and RTX-224, primarily from clinical research organization (CRO) and internal maufacturing costs incurred in connection with all three programs. Additionally, platform development, early-stage research and other unallocated expenses increased by $5.6 million due principally to increases of $2.4 million in personnel-related costs and $0.9 million in stock-based compensation related to the increase in headcount to support our expanded operations. Contract research and development and laboratory supplies also increased to support drug discovery and platform development activities.
G&A expenses were $12.6 million during the first quarter of 2022, compared to $13.2 million for the first quarter of 2021. The lower costs were primarily driven by a reduction in stock-based compensation related to stock option awards that fully vested during the third quarter of 2021.
As of March 31, 2022, cash, cash equivalents and investments were $176.5 million, compared to $225.8 million as of December 31, 2021, providing Rubius with a cash runway into the second half of 2023. During the quarter, the Company used $47.1 million of cash to fund operations and $2.4 million to fund capital expenditures, consisting mostly of renovation costs incurred at our manufacturing facility.
