The results of this research found that, in a pooled analysis of 198,062 pregnant women, 2.2% were HPA-1a negative and 32.3% of these women were also HLA-DRB3*01:01 positive and therefore at ~25-fold higher risk for alloimmunization. These rates are consistent with Rallybio’s current estimate of annual at-risk pregnancies and translate to tens of thousands of fetuses and newborns at risk each year for the potentially devastating consequences of FNAIT.\n\n\n“We are pleased to establish a robust foundation of knowledge documenting the frequency of FNAIT risk as reported from a pooled analysis of peer-review literature, which is consistent with our current estimates,” said Stephen Uden, M.D., Chief Executive Officer of Rallybio. “This information, in combination with data from our ongoing FNAIT natural history study, will enable us to create a shared understanding of the number of pregnant women and babies at higher risk of FNAIT annually, underscoring the importance of having an effective preventative therapeutic option.”\n\n\nRallybio is developing RLYB212, a novel human monoclonal anti-HPA-1a antibody designed to prevent alloimmunization in pregnant women, thereby eliminating the risk of FNAIT and its potentially devastating consequences in their fetuses and newborns. Rallybio is on track to initiate a Phase 2 dose confirmation study for RLYB212 in pregnant women in the second half of 2024. The company is also conducting an ongoing FNAIT natural history study that will provide a contemporary dataset for HPA-1a alloimmunization frequency in a racially and ethnically diverse population, which is intended to support a fut...
