NEW HAVEN, Conn.--(BUSINESS WIRE)--
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 provided an update on recent accomplishments and announced expected 2023 clinical milestones. The Company will present these updates at the 41st Annual J.P. Morgan Health Care Conference in San Francisco, California on Tuesday, January 10, 2023, at 3:45 p.m. PT (6:45 p.m. ET).
“In 2022, Rallybio's first full year as a public company, we made significant progress in our mission to develop transformative therapeutics for rare diseases with severe unmet needs,” said Martin Mackay, Ph.D., Chief Executive Officer of Rallybio. “Over the past 12 months, we announced encouraging preliminary data for our two lead assets, RLYB212, for the prevention of FNAIT, and RLYB116, our C5 inhibitor. We also significantly expanded our earlier-stage pipeline through strategic business development efforts.”
Dr. Mackay continued, “We are excited to build on this progress in 2023. We remain on track to announce Phase 1b proof-of-concept data for RLYB212 in the first quarter and, following the initiation of the multiple ascending dose Phase 1 study of RLYB116 in the fourth quarter of 2022, expect to report initial data in the second half of 2023. In parallel, we continue to seek transformative assets and partners globally in order to address substantial unmet needs and deliver improved outcomes to many more people around the world.”
Recent Portfolio Milestones and Expected Upcoming Milestones
Maternal Fetal Blood Disorders
Rallybio expects to announce Phase 1b proof-of-concept data for RLYB212, a novel human monoclonal anti-HPA-1a antibody in development for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT), in the first quarter of 2023. The Company commenced dosing under an amended protocol of this ongoing study to evaluate a higher dose of RLYB212 in September 2022. The Company expects the broad range of pharmacokinetic and pharmacodynamic data from this study to enable substantive modeling of the concentration-effect relationship and further inform dosing for a future registrational study of RLYB212.
In addition, Rallybio is advancing its FNAIT natural history alloimmunization study. This non-interventional study is designed to provide key information on the frequency of women at higher risk for FNAIT across a broad population of pregnant women of different racial and ethnic characteristics, and the occurrence of HPA-1a alloimmunization in these women. The Company expects that the data from this study will contribute to a control dataset for a future, single-armed registration trial for RLYB212.
Complement Dysregulation
Rallybio announced today that it initiated dosing in the first multiple ascending dose cohort of a Phase 1 study of RLYB116 in the fourth quarter of 2022. RLYB116 is a novel, potentially long-acting, subcutaneously administered inhibitor of complement component 5, or C5, in development for the treatment of patients with complement-related diseases. The single-blind, dose escalation, placebo-controlled study is designed to evaluate the safety, pharmacokinetics, and pharmacodynamics of RLYB116 in healthy participants. Initial data are expected in the second half of 2023.
Rallybio also continues to advance the development of RLYB114, formulated for intravitreal injection, for the treatment of ophthalmic disorders.
Hematological Disorders
Rallybio continues to conduct investigational new drug (IND)-enabling activities for RLYB331, a preclinical, potentially first-in-class therapeutic monoclonal antibody that inhibits Matriptase-2 (MTP-2), to support the transition of this asset into clinical development.
Metabolic Disorders
Rallybio, together with its partner Exscientia, continues to work toward the selection of a small molecule development candidate to advance into the clinic targeting ENPP1 for the treatment of patients with hypophosphatasia (HPP). In vivo efficacy data are expected in the second half of 2023. Following those results, the companies expect to commence IND-enabling studies.
In December 2022, Rallybio announced a strategic alliance with AbCellera to discover, develop, and commercialize novel antibody-based therapeutics for rare diseases. Under the terms of the agreement, AbCellera and Rallybio will co-develop up to five rare disease therapeutic targets, which will be chosen together by both companies. The partnership’s first program will focus on addressing the significant unmet therapeutic needs of patients with rare metabolic diseases.
Financial Update
In November 2022, Rallybio announced the pricing of a follow-on offering of approximately $55 million in gross proceeds. J.P. Morgan, Cowen and Evercore ISI acted as joint lead book-running managers for the offering.
Cash, cash equivalents, and marketable securities were $132.4 million as of September 30, 2022, and with the November 2022 follow-on offering, the Company currently expects its cash runway to extend into the first quarter of 2025.

A live webcast of the presentation and subsequent question and answer session will be accessible through the Events and Presentations section of Rallybio’s website.
