Rallybio to Present Results of Epidemiological Analysis Demonstrating FNAIT Risk Across Racially and Ethnically Diverse Populations at the NORD Breakthrough Summit

Rhea-AI Summary

Rallybio (Nasdaq: RLYB), a clinical-stage biotech company, will present full data from an epidemiological analysis at the NORD Rare Diseases & Orphan Products Breakthrough Summit from October 20-22, 2024, in Washington DC. The analysis quantifies the proportion of women across diverse populations at higher risk of a fetal and neonatal alloimmune thrombocytopenia (FNAIT)-impacted pregnancy.

CEO Stephen Uden emphasized the significance of this data, stating it provides the first clear evidence that non-Caucasian populations can carry a higher risk for FNAIT. This aligns with the summit's theme of 'Equitable Access to Innovation'. The poster will be available on Rallybio's website after the conference.

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, announced today that full data from an epidemiological analysis quantifying the proportion of women across diverse populations at higher risk of a fetal and neonatal alloimmune thrombocytopenia (FNAIT)-impacted pregnancy will be presented at the NORD Rare Diseases & Orphan Products Breakthrough Summit to be held October 20 – 22, 2024 in Washington DC.

“Consistent with the NORD Summit theme of ‘Equitable Access to Innovation,’ our epidemiological analysis is particularly pertinent, providing the first clear evidence of the extent to which non-Caucasian populations can carry a higher risk for FNAIT,” said Stephen Uden, M.D., Chief Executive Officer of Rallybio. “We look forward to sharing this data and its implications at the upcoming conference.”

The poster will be available in the Publications & Presentations section of Rallybio’s website following the conclusion of the conference. More information on the NORD Rare Diseases & Orphan Products Breakthrough Summit can be found here.

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 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.
