Drug Digest: Engineering LNPs Beyond the Liver for Genetic Medicines

Biopharma News

Today's BioPharm Brief explores three developments in Alzheimer's disease and autoimmune research, including promising preclinical gene therapy data, a new FDA-approved at-home treatment option, and a licensing deal for a novel CD40L-targeting antibody.

Today's BioPharm Brief highlights advances in neurology, hematology, and nephrology, featuring new Alzheimer's disease biomarker data, an expanded pediatric approval for von Willebrand disease prophylaxis, and the first dual BAFF and APRIL inhibitor approved for IgA nephropathy.

Vaccinex will present new biomarker data from the Phase 1b/2 SIGNAL-AD trial of pepinemab — a humanized IgG4 monoclonal antibody targeting Semaphorin 4D — at AAIC 2026 in London on July 13, showing that SEMA4D blockade regulates glial biomarkers associated with disease progression in early Alzheimer's disease, while outlining plans for an enlarged Phase 2b SIGNAL-AD2 study.

The FDA has approved an expanded indication for Wilate (von Willebrand Factor/Coagulation Factor VIII Complex, Human) to include routine prophylaxis in children younger than 6 years with von Willebrand disease — the first FDA-approved option for this age group — based on phase 3 WIL-33 trial data showing significantly reduced bleeding episodes in young pediatric patients.

The FDA has granted accelerated approval to Trutakna, a recombinant fusion protein that simultaneously inhibits BAFF and APRIL, for adults with primary IgA nephropathy at risk for disease progression — marking the first approval of a dual BAFF/APRIL inhibitor in the US and a significant advance in the growing wave of targeted biologics for this immune-mediated kidney disease.
