NEW HAVEN, Conn., August 8, 2024 -- Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company translating scientific advances into transformative therapies for patients with devastating rare diseases, today reported second quarter financial results for the period ended June 30, 2024, and provided an update on recent company developments.
“We are working expeditiously towards the initiation of our Phase 2 dose confirmation trial for RLYB212 in pregnant women at higher risk of fetal and neonatal alloimmune thrombocytopenia (FNAIT), which is on track for the fourth quarter of 2024," said Stephen Uden, M.D., Chief Executive Officer of Rallybio. "Recent data from our large-scale genomic analysis of FNAIT risk across a broad population of diverse ancestries provides the first clear evidence that the proportion of pregnant women at higher risk for FNAIT each year has been significantly underestimated, giving us even greater urgency to bring RLYB212 to this underserved population that comprises a market opportunity of more than $1.6 billion. We look forward to providing updates as we continue to advance our RLYB212 program with a team of highly dedicated investigators who share our mission to prevent this devastating disease."
Recent Business Highlights and Upcoming Milestones:
Corporate Updates
•In April 2024, Rallybio announced a collaboration with Momenta Pharmaceuticals, Inc., a Johnson & Johnson Company, to advance complementary therapeutic solutions for pregnant women at risk of FNAIT. Rallybio received an equity investment of $6.6 million, before deducting offering expenses, from Johnson & Johnson Innovation – JJDC, Inc. In addition, Rallybio received an upfront payment of $0.5 million related to the collaboration and license agreement with Johnson & Johnson.
RLYB212 Program
•Rallybio remains on track to initiate a Phase 2 trial in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT in the fourth quarter of 2024. The primary objectives of this trial are to assess the pharmacokinetics and safety of subcutaneously administered RLYB212 in pregnant women. Secondary objectives include assessments of pregnancy and neonatal outcomes, and the occurrence of emergent HPA-1a alloimmunization. Administration of RLYB212 will be initiated by Gestational Week 16 and continue every 4 weeks through parturition.
•The Company reported top line results from an epidemiological analysis that provided the first clear and robust evidence quantifying the proportion of women of non-Caucasian ancestries that carry the genetic markers for higher FNAIT risk (HPA-1a negative, HLA-DRB3*01:01 positive). These data indicate that the proportion of pregnant women at higher risk for FNAIT each year has been significantly underestimated. Specifically, in key geographies of North America and major European countries, it is estimated that more than 30,000 pregnancies each year are at higher risk for FNAIT, representing a 40% increase from prior estimates. Full data from the epidemiological analysis are expected to be presented at a scientific conference in the fourth quarter of 2024.
•Screening in the Company's FNAIT natural history study is ongoing, with more than 12,000 pregnant women screened as of August 1, 2024. In the third quarter of 2024, Rallybio will begin to transition European sites from the natural history study to the Phase 2 trial, where sites will continue to collect natural history data in women who are not administered RLYB212. North American sites will continue to screen pregnant women in the natural history study which will be progressed in parallel with the Phase 2 trial. The totality of natural history data from both studies is designed to provide a contemporary dataset for HPA-1a alloimmunization frequency in a racially and ethnically diverse population that can serve as a control arm for the planned Phase 3 trial.
•Several presentations and publications are expected in the second half of 2024, including additional data from the Phase 1b proof-of-concept study and the rationale and modeling that support the RLYB212 Phase 2 dose regimen.
RLYB116 Program
•RLYB116 manufacturing work is progressing and is on track to be completed in the third quarter of 2024. Drug substance characterization data indicates that Rallybio's efforts to enhance the manufacturing process have been successful.
•Additional complement biomarker analysis for RLYB116 is ongoing, with full data expected in the fourth quarter of 2024. This work expands our understanding of the results of the Phase 1 multiple ascending dose (MAD) study, which was completed in the fourth quarter of 2023. Based on these analyses, Rallybio believes that there is an opportunity to pursue indications beyond generalized myasthenia gravis (gMG), including paroxysmal nocturnal hemoglobinuria (PNH) and antiphospholipid syndrome (APS), at doses tested in the Phase 1 MAD study.
•The Company will provide an update on future plans for RLYB116 later this year.
Preclinical Programs
In accordance with its 2024 operating plan, Rallybio is advancing its preclinical programs to important 2024 milestones. Beyond achievement of these milestones, Rallybio is seeking alternative options to further advance its preclinical programs, including partnerships and other forms of non-dilutive financing.
•RLYB332: Presentation of nonclinical data demonstrating favorable tolerability, dose-dependent pharmacokinetics, and sustained pharmacodynamic effects with RLYB332, a long-acting version of the RLYB331 anti-matriptase-2 antibody, is expected in the fourth quarter of 2024.
•ENPP1 Inhibitor, Exscientia Partnership: Rallybio and Exscientia expect to achieve development candidate nomination of a small molecule inhibitor of ENPP1 for the treatment of patients with hypophosphatasia (HPP) in the fourth quarter of 2024. In addition, data from an early lead compound in a nonclinical model of HPP will be presented at the American Society for Bone and Mineral Research (ASBMR) meeting which is being held from September 27 – 30, 2024 in Toronto, ON, Canada.
Second Quarter 2024 Financial Results
•Revenue: Revenue was $0.3 million for the second quarter of 2024, compared to no revenue in the same period in 2023. The increase was related to Rallybio's entrance into the collaboration and license agreement with Johnson & Johnson in the second quarter of 2024 and the recognition of revenue related to the collaboration's performance obligations.
•Research & Development (R&D) Expenses: R&D expenses were $12.9 million for the second quarter of 2024, compared to $13.1 million for the same period in 2023. The decrease in R&D expense was primarily due to a decrease in payroll and personnel-related costs, largely offset by an increase in development costs related to RLYB212 and RLYB116.
•General & Administrative (G&A) Expenses: G&A expenses were $4.4 million for the second quarter of 2024, compared to $7.0 million for the same period in 2023. The decrease in G&A expense was primarily related to lower payroll and personnel-related costs, largely related to the workforce reduction and lower ongoing headcount in 2024 as compared to 2023, and reductions in consulting fees, director and officer insurance premiums, professional fees and other G&A expenses.
•Net Loss and Net Loss Per Common Share: Rallybio reported a net loss of $16.2 million, or $0.37 per common share, for the second quarter of 2024. This compares to a net loss of $18.6 million, or $0.46 per common share, for the second quarter of 2023.
•Cash Position: As of June 30, 2024, cash, cash equivalents, and marketable securities were $88.6 million.
