NEW HAVEN, Conn. March 12, 2024-- Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company committed to identifying and accelerating the development of life-transforming therapies for patients with severe and rare diseases, today reported financial results for the fourth quarter and full year ended December 31, 2023 and provided an update on recent program and corporate developments.
“We are encouraged by the continued progress we made across our portfolio throughout 2023. Following our February 2024 announcement regarding the prioritization of our portfolio and reorganization of our operations, we believe our existing capital will fund our revised operating plan into the middle of mid-2026 and intend to focus our efforts in 2024 on our clinical-stage programs, RLYB212 and RLYB116. We have received feedback from the European Medicines Agency for RLYB212 and are pleased to now move forward with the clinical trial application process in Europe where we will conduct the Phase 2 dose confirmation study for RLYB212 in pregnant women at higher risk for FNAIT. The Phase 2 study remains on track to initiate in the second half of 2024,” said Stephen Uden, M.D., Chief Executive Officer of Rallybio.
Dr. Uden continued, “In parallel, the manufacturing work for RLYB116 is ongoing and we are encouraged by the data indicating the potential to achieve improved tolerability at higher doses. We expect to complete this work and provide an update on the development plan for RLYB116 in the second half of 2024. We also remain committed to advancing our preclinical programs to the next milestone and will seek alternative options to advance and or finance these programs with a goal of realizing the value of these programs.”
Recent Business Highlights and Upcoming Milestones:
Corporate Updates
In February 2024, Rallybio announced a prioritization of its portfolio and 45% workforce reduction to focus the Company’s resources on its two Phase 2 ready assets, RLYB212, a novel human monoclonal anti-HPA-1a antibody in development for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT), and RLYB116, a once-weekly, low volume subcutaneously injected inhibitor of complement component 5 (C5) in development for patients with complement mediated diseases. With these changes, Rallybio announced that the Company expects its cash runway to extend into the middle of 2026.
The workforce reduction included 19 roles and will be substantially complete by the end of the first quarter of 2024. Rallybio estimates that the workforce reduction will result in aggregate charges of approximately $3.3 million primarily for one-time employee severance and benefit costs, excluding share-based compensation expense.
Maternal Fetal Blood Disorders
In November 2023, Rallybio announced preliminary data from the completed multiple dose cohort of the Phase 1 safety and pharmacokinetics (PK) study for RLYB212. The Phase 1 multiple dose cohort for RLYB212 was initiated in the first quarter of 2023 to evaluate the safety and PK of subcutaneous (SC) RLYB212 based on repeat dosing over 12 weeks. The preliminary data demonstrated that multiple dose PK were consistent both within and between subjects and, together with the Company’s clinical pharmacology modeling predictions, support a once monthly dosing regimen for the planned Phase 2 study in pregnant women at higher risk for FNAIT. Consistent with previously reported data, RLYB212 was observed to be generally well-tolerated with no reports of injection site reactions or serious adverse events.
Rallybio announced today that the Company has received Protocol Assistance Feedback from the European Medicines Agency (EMA) on the RLYB212 Phase 2 study, and the Company is now moving forward with Clinical Trial Applications to support conduct of the Phase 2 study in Europe. Rallybio continues to expect to initiate the Phase 2 dose confirmation study in pregnant women at higher risk for FNAIT in the second half of 2024.
The Company continues to screen in the FNAIT natural history alloimmunization study, a non-interventional study designed to provide a contemporary dataset for HPA-1a alloimmunization frequency in a racially and ethnically diverse population. The Company expects screening for the natural history study to continue simultaneously with execution of the Phase 2 dose confirmation study. As of March 1, 2024, Rallybio has screened approximately 9,400 women in the natural history study, and expects to screen between 20,000 and 30,000 women in the study.
Complement Dysregulation
In December 2023, Rallybio announced preliminary Phase 1 multiple ascending dose data for RLYB116. Results demonstrated that a 100 mg low volume once-a-week dose of subcutaneously administered RLYB116 achieved sustained mean reductions in free C5 of greater than 93%. In addition, RLYB116 administered as a 100 mg once-a-week dose was observed to be generally well tolerated with injection site reaction as the most common adverse event (AE) in the cohort, occurring in 60% of the participants in the cohort. All AEs with the 100 mg weekly dose were mild in severity.
While the exposure concentrations of RLYB116 demonstrated in the Phase 1 study are expected to be suitable for the treatment of patients with generalized myasthenia gravis, the Company believes ongoing manufacturing enhancements will enable higher exposure to RLYB116, supporting the treatment of patients with a broader range of complement-mediated diseases, including paroxysmal nocturnal hemoglobinuria and antiphospholipid syndrome. The manufacturing work is progressing and Rallybio is encouraged by the data indicating the potential to achieve improved tolerability at higher doses.
Rallybio continues to expect to complete this manufacturing work in the second half of 2024 and to provide an update on the development plan for RLYB116 at that time.
Rallybio, together with its partner EyePoint Pharmaceuticals, Inc., continue to evaluate sustained delivery of Rallybio’s inhibitor of C5 using EyePoint’s proprietary technology for sustained intraocular drug delivery. Rallybio and EyePoint expect to provide an update on this collaboration in the first half of 2024.
Preclinical Programs
The revised operating plan will fund preclinical program activities to important 2024 milestones, as described below. Beyond achievement of these milestones, Rallybio will seek alternative options to further advance these programs, including additional partnerships and other forms of non-dilutive financing.
•RLYB331, Matriptase-2 (MTP-2) Inhibitor: Completion of the ongoing preclinical activities, with data expected in the first half of 2024.
•ENPP1 Inhibitor, Exscientia Partnership: Lead AI-designed compounds enter candidate selection process in the second half of 2024.
•AbCellera Partnership: Advancement of discovery efforts to the next research milestone in the second half of 2024.
Fourth Quarter and Full Year 2023 Financial Results
•Research & Development (R&D) Expenses: R&D expenses were $15.9 million for the fourth quarter of 2023, compared to $10.8 million for the same period in 2022. R&D expenses for the fourth quarter 2023 increased primarily due to an increase in costs to advance RLYB212, RLYB116 and RLYB331 as compared to the prior year. R&D expenses were $53.5 million for the year ended December 31, 2023 compared to $40.7 million for the year ended December 31, 2022. R&D expenses for the year ended December 31, 2023 increased primarily due to an increase in costs to advance RLYB212, RLYB116 and RLYB331 and additional R&D related headcount costs, including share-based compensation expense as compared to the prior year. These costs were offset by a decrease in R&D asset acquisition costs and R&D costs related to RLYB114.
•General & Administrative (G&A) Expenses: G&A expenses were $5.2 million for the fourth quarter of 2023, compared to $6.3 million for the same period in 2022. G&A expenses for the fourth quarter of 2023 decreased primarily due to a decrease in payroll and personnel-related costs, lower director and officer insurance premiums and lower other general and administrative related expenses as compared to the prior year. G&A expenses were $25.4 million for the year ended December 31, 2023 compared to $27.2 million for the year ended December 31, 2022. The decrease in G&A expenses for the year ended December 31, 2023 was primarily due to a decrease in payroll and personnel-related costs and lower director and officer insurance premiums; offset by increases in other general and administrative related expenses.
•Net Loss and Net Loss Per Common Share: Net loss was $20.2 million for the fourth quarter of 2023, or net loss per common share of $0.50 compared to a net loss of $16.2 million, or net loss per common share of $0.46 for the fourth quarter of 2022. Net loss was $74.6 million, or net loss per share of $1.84, for the year ended December 31, 2023 compared to $66.7 million, or net loss per share of $2.09, for the year ended December 31, 2022.
•Cash Position: As of December 31, 2023, cash, cash equivalents, and marketable securities were $109.9 million.
