This segment focuses on the development of therapies for the prevention and treatment of Fetal and Neonatal Alloimmune Thrombocytopenia (FNAIT), a severe condition affecting newborns. Rallybio's lead product candidate, RLYB212, is a preclinical-stage monoclonal anti-HPA-1a antibody designed to prevent FNAIT. The company is also developing RLYB211, a polyclonal anti-HPA-1a antibody currently in a Phase 1/2 clinical trial. Research and development activities include preclinical studies, clinical trial management, and manufacturing process development. The goal is to improve outcomes for infants affected by FNAIT, reducing the risk of intracranial hemorrhage and other complications. Market positioning involves addressing an unmet medical need in the rare disease space, with potential for partnerships and collaborations to accelerate development and commercialization. Future opportunities include expanding the therapeutic applications of anti-HPA-1a antibodies and exploring combination therapies.

This segment concentrates on developing therapies for complement-mediated ophthalmic diseases and other conditions. Rallybio is developing RLYB114, a pegylated C5 inhibitor in preclinical development for the treatment of these diseases. Additionally, RLYB116, a subcutaneously administered inhibitor of complement factor 5 (C5), is being developed for paroxysmal nocturnal hemoglobinuria (PNH) and generalized myasthenia gravis (gMG). Research and development efforts include preclinical studies, clinical trial design and execution, and manufacturing process optimization. The focus is on addressing diseases where the complement system plays a significant role, aiming to improve patient outcomes by reducing inflammation and tissue damage. Market positioning involves targeting specific patient populations with high unmet medical needs, with potential for partnerships and collaborations to expand the pipeline and accelerate clinical development. Future opportunities include exploring the use of complement inhibitors in additional disease areas and developing novel formulations and delivery methods.

This segment is dedicated to the discovery and development of small molecule therapeutics for patients with rare metabolic diseases. Rallybio is actively engaged in identifying and evaluating potential drug candidates through its internal research programs and collaborations. The company is leveraging its expertise in drug discovery and development to identify novel therapeutic targets and develop innovative treatment approaches. Research and development activities include target identification, lead optimization, preclinical studies, and clinical trial planning. The focus is on addressing the unmet medical needs of patients with rare metabolic disorders, aiming to improve their quality of life and overall health outcomes. Market positioning involves targeting specific patient populations with limited treatment options, with potential for partnerships and collaborations to accelerate drug development and commercialization. Future opportunities include expanding the pipeline of small molecule therapeutics and exploring the use of advanced technologies to enhance drug discovery and development efforts.
