BillionToOne (Nasdaq: BLLN) launched Northstar Origin, a physician-ordered liquid biopsy add-on test that predicts tissue of origin from circulating cell-free DNA for patients with cancer of unknown primary or uncertain diagnoses, using the same blood draw as the Northstar Select assay.
The company reports that Northstar Origin, combining methylation profiling with tissue-specific somatic variants, correctly identified the primary site as its top prediction in 87% of 1,578 validation cases and within the top three in 91%. BillionToOne also expanded its Northstar Select comprehensive genomic profiling panel from 84 to 102 genes, adding 18 genes including MTAP deletion while maintaining stated sensitivity.
BillionToOne (Nasdaq: BLLN) reported publication in The Green Journal of a large prospective, multi-site study evaluating its Unity Fetal Risk Screen cfDNA test for recessive conditions in a general-risk pregnancy population. The study followed 2,212 pregnant carriers at nine U.S. institutions where partner carrier status was unknown, mirroring routine prenatal practice.
According to BillionToOne, pregnancy outcomes were collected for 98.6% of eligible cfDNA results. Unity Fetal Risk Screen showed 94.4% sensitivity, 99.5% specificity, and >99.9% negative predictive value for cystic fibrosis, spinal muscular atrophy, and alpha- and beta-hemoglobinopathies, and delivered personalized fetal risk estimates ranging from as high as 9-in-10 to as low as 1-in-10,000. The company said performance was consistent across a racially and ethnically diverse population and that the data strengthen the evidence for using cfDNA fetal risk assessment as a primary screen within its Unity Complete prenatal portfolio.
BillionToOne (Nasdaq: BLLN) reported publication in The Green Journal of a prospective, multi-site study evaluating its Unity Fetal Risk Screen cfDNA test for recessive conditions in a large, general-risk pregnancy population.
The nine-center U.S. study followed 2,212 pregnant carriers whose partners’ carrier status was unknown, with outcomes collected for 98.6% of pregnancies completing care. Unity Fetal Risk Screen assessed fetal risk for cystic fibrosis, spinal muscular atrophy, and alpha- and beta-hemoglobinopathies, demonstrating 94.4% sensitivity, 99.5% specificity, and >99.9% negative predictive value. According to BillionToOne, traditional carrier screening classifies fewer than 50% of affected pregnancies as high risk, largely due to incomplete partner testing, while Unity directly estimates fetal risk, providing personalized probabilities from as high as 9-in-10 to as low as 1 in 10,000. Performance was consistent across racially and ethnically diverse groups, and the test is part of the Unity Complete prenatal portfolio, which the company is expanding with a new 130-gene fetal risk panel.

BillionToOne (Nasdaq: BLLN) reported peer-reviewed data showing its Northstar Response tissue-free ctDNA assay was a stronger independent predictor of survival than standard-of-care imaging in 142 advanced solid tumor patients across 12 tumor types receiving immunotherapy.
Molecular progression via Northstar Response showed a hazard ratio of 5.3 for survival and identified progression a median of 62 days before clinicoradiographic imaging. Combining Northstar Response with imaging produced the highest predictive discrimination, with hazard ratios up to 19.7 when both modalities indicated progression.
