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 highlighted its 2024 accomplishments and announced its anticipated key milestones for 2025.
“With our team’s innovation and execution throughout 2024, Rallybio is well positioned to create meaningful value in 2025,” said Stephen Uden, M.D., Chief Executive Officer of Rallybio. “We are planning for key readouts from our RLYB212 and RLYB116 clinical programs and expecting important advancements in our REV102 program throughout the year. We believe these developments will provide further evidence of the value our programs can ultimately bring to patients. With these accomplishments and continued financial discipline, the Company is poised for significant momentum in 2025 and even greater success in the years to come.”
2024 Accomplishments
RLYB212
Obtained clinical trial application approvals and initiated the first-ever Phase 2 dose confirmation trial in pregnant women at higher risk for HPA-1a alloimmunization and fetal and neonatal alloimmune thrombocytopenia (FNAIT)
Screened more than 14,000 pregnant women through January 1, 2025 in the Company’s ongoing FNAIT natural history study
Presented results of an epidemiological analysis demonstrating FNAIT risk across racially and ethnically diverse populations, indicating that more than 30,000 pregnancies each year are at higher risk for FNAIT, at the NORD Summit and ASHG
Published Phase 1b proof-of-concept results, in addition to the modeling and simulations that support the RLYB212 dose regimen for the Phase 2 trial
RLYB116
Successfully completed manufacturing process enhancements, which are expected to further improve the tolerability of RLYB116
Presented biomarker characterization analyses indicating that RLYB116 led to a greater degree of complement inhibition in the Phase 1 MAD study than initially reported
REV102
Advanced REV102, an ENPP1 inhibitor for the treatment of patients with hypophosphatasia (HPP) which was discovered in partnership with Recursion Pharmaceuticals
Presented data at ASBMR from an early lead ENPP1 inhibitor, REV101, in a mouse model of later-onset HPP demonstrating a 30% reduction in inorganic pyrophosphate (PPi), a key biomarker that is elevated in HPP and contributes to poor bone mineralization
RLYB332
Presented preclinical data for RLYB332 at ASH, including favorable pharmacodynamic (PD) data, supporting RLYB332 as a long-acting, potentially best-in-class therapy for the treatment of diseases of iron overload
FNAIT Natural History Study Update
Rallybio plans to conclude screening in the FNAIT natural history study in the United States and Canada as of January 31, 2025. The Company will focus resources on advancing the RLYB212 Phase 2 trial across sites in Europe, including initiation of dosing in the sentinel participant and collection of natural history data in a sub-study of the Phase 2 trial. Participants identified as having higher risk for HPA-1a alloimmunization and FNAIT in the ongoing Phase 2 trial who do not receive RLYB212 are eligible to enroll in the natural history sub-study of the Phase 2 trial.
Anticipated 2025 Key Milestones
RLYB212
Initiate dosing of sentinel participant in the Phase 2 trial in the second quarter of 2025
Present interim data from the FNAIT natural history study in mid-2025
Report interim safety and pharmacokinetic (PK) data from the Phase 2 trial sentinel participant in the third quarter of 2025
Completion of pregnancy, with safety and PK data readout, from the Phase 2 trial sentinel participant in the fourth quarter of 2025
RLYB116
Initiate confirmatory clinical PK/PD study in the second quarter of 2025
Cohort 1 data readout from clinical PK/PD study in the third quarter of 2025
Cohort 2 data readout from clinical PK/PD study in the fourth quarter of 2025
REV102
Initiate investigational new drug application (IND)-enabling studies in 2025 to support the initiation of a Phase 1 study in 2026
Report REV102 data from a preclinical model of later-onset HPP in the second half of 2025
