Rallybio Announces FNAIT Systematic Literature Review to be Presented at the AMCP 2024 Annual Meeting


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 announced that data from a systematic literature review assessing the frequency of fetal and neonatal alloimmune thrombocytopenia (FNAIT) risk among pregnant mothers will be presented at the Academy of Managed Care Pharmacy (AMCP) 2024 Annual Meeting in New Orleans from April 15th to 18th. Rallybio is developing RLYB212, a novel human monoclonal anti-HPA-1a antibody designed to prevent alloimmunization in at-risk pregnant mothers, thereby eliminating the risk of FNAIT and its potentially devastating consequences in fetuses and newborns.

Details of the poster presentation are as follows:

  • Title: Fetal and Neonatal Alloimmune Thrombocytopenia: A Systematic Literature Review and Meta-analysis of Adverse Pregnancy-Related Outcomes to Support the Development of a Novel Prophylactic Therapeutic
  • Presenting Author: Andrea V. Margulis, RTI Health Solutions
  • Poster Number: P1
  • Poster Session Date and Time: April 17, 2024, 1:00 - 2:30 p.m. CDT (2:00 - 3:30 p.m. EDT)

About FNAIT

Fetal 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 alloimmunizaion. 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.
