Acumen Pharmaceuticals (NASDAQ: ABOS) presented new preclinical and biomarker data at AD/PD 2026 (March 17-21) on enhanced brain delivery, NULISAseq biomarker profiling, and novel anti-amyloid beta oligomer antibodies. Key findings: TfR-targeted bispecifics increased sabirnetug brain exposure, NULISAseq measured 127 CNS proteins, and ACU234 showed ~21,000-fold oligomer selectivity.
The data support further characterization and integration with ongoing Phase 2 ALTITUDE‑AD and prior Phase 1 INTERCEPT‑AD results.

Acumen Pharmaceuticals (NASDAQ: ABOS) will present one oral and two poster presentations at the AD/PD conference in Copenhagen, March 17–21, 2026. Presentations cover enhanced brain delivery (EBD™) of sabirnetug, sabirnetug biomarker responses (NULISA-Seq-TM), and novel AβO-targeting antibodies.
The oral talk on March 21 details fusion of sabirnetug with an anti-transferrin receptor fragment; posters on March 17–18 cover biomarker analytics and antibody characterization. The oral data arise from an ongoing collaboration with JCR Pharmaceuticals using J-Brain Cargo® technology and support analytic plans for Phase 2 ALTITUDE‑AD.
Acumen Pharmaceuticals (NASDAQ: ABOS) presented new preclinical and clinical-trial recruitment data at the 18th Annual CTAD conference on December 1-4, 2025. A collaborative study with JCR Pharmaceuticals showed that fusing transferrin receptor (TfR) binders to AβO-targeting antibodies (including sabirnetug/ACU193) produced 15–68 fold increases in brain penetration in mice while preserving target binding. Acumen and JCR are developing TfR-targeting antibodies for clinical testing. Recruitment analysis from the Phase 2 ALTITUDE-AD trial tracked 2,362 screened across 76 sites with 542 enrolled, finding site databases and physician referrals were the most reliable recruitment methods.
