Rallybio Reports First Quarter 2025 Financial Results and Provides Business Updates
NEW HAVEN, Conn.--(BUSINESS WIRE)--Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company translating scientific advances into transformative therapies for patients with devastating rare diseases, today reported first quarter financial results for the period ended March 31, 2025, and provided an update on recent company developments. 'We are focused on advancing RLYB116 into a confirmatory pharmacokinetic/pharmacodynamic study this quarter, and believe that data from this study will demonstrate RLYB116's potential to be a best-in-class therapeutic for patients with complement-driven diseases,' said Stephen Uden, M.D., Chief Executive Officer of Rallybio. 'Leveraging our team's deep expertise in the complement field, we are well-positioned to maximize RLYB116's transformative potential across multiple billion-dollar market opportunities. Additionally, we believe significant value resides within our preclinical pipeline, which includes REV102 and RLYB332. By advancing our innovative pipeline, we are committed to creating exceptional value for our shareholders while delivering life-changing therapies to patients who need them most.' Recent Business Highlights and Upcoming Milestones: RLYB116 Program Rallybio is on track to initiate dosing in the RLYB116 confirmatory clinical pharmacokinetic/pharmacodynamic (PK/PD) study in the second quarter of 2025. Results from Cohort 1 (150 mg once weekly) and Cohort 2 (225 mg once weekly) are anticipated in the third and fourth quarter of 2025, respectively. Data from this study are expected to demonstrate complete and sustained complement inhibition with improved tolerability of RLYB116. REV102 Program Investigational new drug application (IND)-enabling studies are underway for REV102, an ENPP1 inhibitor for the treatment of patients with hypophosphatasia (HPP), which is being developed through a joint venture with Recursion Pharmaceuticals. These studies are expected to support the initiation of a Phase 1 study in the second half of 2026. Presentation of data evaluating REV102 in a preclinical model of later-onset HPP is expected in the second half of 2025. RLYB332 Program Rallybio continues to evaluate plans for future development of RLYB332, a long-acting, monoclonal anti-matriptase-2 antibody that has the potential to be a best-in-class treatment for diseases of iron overload. Preclinical data has demonstrated superior impact on PD parameters relative to comparator molecules, including serum iron, unsaturated iron binding capacity (UIBC), and transferrin saturation (TSAT). RLYB212 Program In April 2025, Rallybio announced the discontinuation of the RLYB212 program for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT). The Company's decision to discontinue RLYB212 development was based on PK data from the Phase 2 clinical trial demonstrating the inability of the RLYB212 dose regimen to achieve predicted target concentrations, as well as the minimum target concentration required for efficacy. Safety follow-up of the sentinel participant in the Phase 2 trial will continue as specified in the clinical trial protocol. Corporate Update Rallybio is implementing a 40% workforce reduction, representing nine positions, which will be substantially complete by the end of the second quarter of 2025. Rallybio estimates that the workforce reduction will result in aggregate charges of approximately $1.7 million, primarily for one-time employee severance and benefit costs, and excluding share-based compensation expense. First Quarter 2025 Financial Results Revenue: Revenue was $0.2 million for the first quarter of 2025. There was no revenue for the first quarter of 2024. The increase in revenue for the first quarter of 2025 was related to Rallybio's entrance into the collaboration 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 $5.7 million for the first quarter of 2025, compared to $12.9 million for the same period in 2024. The decrease in R&D expenses was primarily due to a decrease in development costs related to RLYB212, RLYB116, and other program candidates, in addition to a decrease in payroll and personnel-related costs, largely related to the workforce reduction in the first quarter of 2024. General & Administrative (G&A) Expenses: G&A expenses were $4.2 million for the first quarter of 2025, compared to $6.9 million for the same period in 2024. The decrease in G&A expenses was primarily due to a decrease in other general and administrative expenses in addition to lower payroll and personnel-related costs, largely related to the workforce reduction in the first quarter of 2024 and lower ongoing headcount in 2025 as compared to 2024. Net Loss and Net Loss Per Common Share: Rallybio reported a net loss of $9.4 million, or $0.21 per common share, for the first quarter of 2025 compared to a net loss of $19.0 million, or $0.47 per common share, for the same period in 2024. Cash Position: As of March 31, 2025, cash, cash equivalents, and marketable securities were $54.5 million. Rallybio expects these funds will be sufficient to support operations into the first half of 2027.

Rallybio to Discontinue Development of RLYB212 for Prevention of FNAIT
– RLYB212 Phase 2 PK Results Did Not Achieve Target Concentrations, Including Minimum Target Concentration Required for Efficacy – – RLYB116 Confirmatory PK/PD Study to Initiate in 2Q 2025, with Data in 2H 2025 – NEW HAVEN, Conn., April 08, 2025--(BUSINESS WIRE)--Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company translating scientific advances into transformative therapies for patients with devastating rare diseases, today announced the discontinuation of the RLYB212 program for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT). The Company's decision to discontinue RLYB212 development was based on pharmacokinetic (PK) data from the Phase 2 clinical trial demonstrating the inability of the RLYB212 dose regimen to achieve predicted target concentrations, as well as the minimum target concentration required for efficacy. Rallybio remains focused on advancing RLYB116, a once-weekly low volume C5 inhibitor for the treatment of complement-driven diseases, as well as its emerging preclinical programs. "We are disappointed by the PK results of the RLYB212 Phase 2 trial," said Stephen Uden, M.D., Chief Executive Officer of Rallybio. "Given that the results significantly deviated from the predicted range and the absence of empiric data to further inform dose adjustment, the risk/benefit no longer supports continued dosing, and we will discontinue RLYB212 development. We are grateful to the participants, investigators, and study staff for their partnership and dedication to this program." Dr. Uden continued, "Rallybio remains steadfast in our mission to develop transformative therapies. We are focused on creating shareholder value by advancing our portfolio of potentially best-in-class assets for patients with rare diseases, which includes RLYB116 and REV102, an ENPP1 inhibitor for patients with hypophosphatasia, as well as RLYB332, a long-acting matriptase-2 antibody for diseases of iron overload." RLYB212 Phase 2 Trial The single-arm Phase 2 dose confirmation trial was designed to assess the PK and safety of RLYB212 in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT. Secondary objectives included the assessment of pregnancy and neonatal/infant outcomes, and the occurrence of emergent HPA-1a alloimmunization. Second trimester PK results from the sentinel participant demonstrated an inability of RLYB212 to achieve predicted target concentrations of 6 ng/mL to 10 ng/mL, as well as the minimum target concentration required for efficacy of 3 ng/mL, with values near or below the assay's lower limit of quantitation. Dose adjustment is not deemed feasible given that PK levels are meaningfully outside the predicted range and the absence of empiric data to inform an adjustment. It is hypothesized that HPA-1a antigen expression on the placenta may be impacting plasma concentrations of RLYB212. No further enrollment in the trial is planned and all screening of participants has been stopped. The Company will continue safety follow-up of the sentinel participant as specified in the clinical trial protocol. Promising Rare Disease Pipeline to Deliver Data in 2H 2025 RLYB116 Program Rallybio remains on track to initiate dosing in the RLYB116 confirmatory clinical pharmacokinetic/ pharmacodynamic (PK/PD) study in the second quarter of 2025, with data readouts from Cohorts 1 and 2 expected in the third and fourth quarter of 2025, respectively. The study is expected to demonstrate complete and sustained complement inhibition with improved tolerability of RLYB116. RLYB116 is a novel antibody mimetic fusion protein designed to inhibit C5 and to provide a once-weekly, small volume, subcutaneously injected therapy to meet patient demand for a convenient, self-administered at-home solution. RLYB116 has the potential to address significant unmet need for patients across a number of complement mediated diseases, including paroxysmal nocturnal hemoglobinuria (PNH), antiphospholipid syndrome (APS), and generalized myasthenia gravis (gMG), which together represent a commercial opportunity of more than $6 billion. Importantly, this strategic focus on complement-mediated diseases presents a unique opportunity for Rallybio to utilize its team's deep domain experience in successfully designing, developing, and delivering complement inhibitors for patients with rare diseases. Preclinical Programs REV102, an ENPP1 inhibitor for the treatment of patients with HPP under development through a joint venture with Recursion Pharmaceuticals, entered investigational new drug application (IND)-enabling studies in the first quarter of 2025 to support the initiation of a Phase 1 study in 2026. Data evaluating REV102 in a preclinical model of later-onset HPP is expected in the second half of 2025. Rallybio's portfolio also includes RLYB332, a long-acting, monoclonal anti-matriptase-2 antibody that has the potential to be a best-in-class treatment for diseases of iron overload. Preclinical data has demonstrated superior impact on PD parameters relative to comparator molecules, including on serum iron, unsaturated iron binding capacity (UIBC), and transferrin saturation (TSAT).

Rallybio Announces Initiation of Dosing in RLYB212 Phase 2 Clinical Trial
– Key Data Readouts from Sentinel Participant Expected in 2Q 2025 and 3Q 2025 – NEW HAVEN, Conn., February 11, 2025--(BUSINESS WIRE)--Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company translating scientific advances into transformative therapies for patients with devastating rare diseases, today announced that the first participant has been dosed in the Phase 2 trial investigating RLYB212 in pregnant women at higher risk for HPA-1a alloimmunization and fetal and neonatal alloimmune thrombocytopenia (FNAIT). Pharmacokinetic (PK) and safety data from the second trimester are expected in the second quarter of 2025, with PK and safety data at the time of delivery expected in the third quarter of 2025. "Dosing the sentinel participant in our RLYB212 Phase 2 trial marks a significant milestone for our RLYB212 program and for Rallybio," said Stephen Uden, M.D., Chief Executive Officer of Rallybio. "In addition to the assessment of safety, we are looking for the PK profile in the sentinel participant to demonstrate the ability of RLYB212 to achieve and maintain target concentrations throughout pregnancy. We plan to provide an update in the second quarter, as we continue to advance our mission to deliver a safe and effective therapeutic to prevent maternal alloimmunization and the potentially catastrophic consequences of FNAIT." The single-arm Phase 2 dose confirmation trial (2024-512651-20/NCT06435845) is designed to assess the PK and safety of RLYB212 in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT. Secondary objectives include assessments of pregnancy and neonatal/infant outcomes, and the occurrence of emergent HPA-1a alloimmunization. Subcutaneous administration of RLYB212 is to be initiated by Gestational Week 16 and continued every 4 weeks through parturition. The Phase 2 trial is designed to enroll participants in three stages: first with a sentinel pregnant woman, followed by an initial cohort (Cohort 1) that will include three pregnant women, and then a second cohort (Cohort 2) that will include four pregnant women, for a total target enrollment of eight participants. A data review for participants and infants is planned prior to the initiation of each cohort. The trial will seek to enroll participants at sites in Europe. About RLYB212RLYB212 is a subcutaneously administered monoclonal anti-HPA-1a antibody in development for the prevention of HPA-1a alloimmunization in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT. RLYB212 is designed to rapidly eliminate HPA-1a positive fetal platelets from a pregnant woman's circulation, thereby preventing maternal HPA-1a alloimmunization. Prevention of maternal alloimmunization eliminates the risk of FNAIT in the fetus. About FNAITFetal and Neonatal Alloimmune Thrombocytopenia (FNAIT) is a potentially life-threatening rare disease that can cause uncontrolled bleeding in fetuses and newborns. FNAIT can arise during pregnancy due to an immune incompatibility between an expectant mother and her fetus in a specific platelet antigen called human platelet antigen 1, or HPA-1. There are two predominant forms of HPA-1, known as HPA-1a and HPA-1b, which are expressed on the surface of platelets. Individuals who are homozygous for HPA-1b, meaning that they have two copies of the HPA-1b allele and no copies of the HPA-1a allele, are also known as HPA-1a negative. Upon exposure to the HPA-1a antigen, these individuals can develop antibodies to that antigen in a process known as alloimmunization. In HPA-1a-negative expectant mothers bearing a HPA-1a-positive fetus, alloimmunization can occur upon mixing of fetal blood with maternal blood. When alloimmunization occurs in an expectant mother, the anti-HPA-1a antibodies that develop in the mother can cross the placenta and destroy platelets in the fetus. The destruction of platelets in the fetus can result in severely low platelet counts, or thrombocytopenia, and potentially lead to devastating consequences including miscarriage, stillbirth, death of the newborn, or severe lifelong neurological disability in those babies who survive. There is currently no approved therapy for the prevention or prenatal treatment of FNAIT.
