Today's BioPharm Brief explores three distinct ways researchers are engineering the immune system, from a first-in-human bispecific T-cell engager for ovarian cancer and the FDA's first regulatory T-cell immunotherapy to promising vaccine data against antibiotic-resistant Shigella.

92Bio, Inc. has dosed the first patient in a Phase 1 trial of NTB-928, a fully human bispecific T-cell engager targeting FOLR1 and CD3, designed to selectively kill FOLR1-overexpressing ovarian cancer cells while sparing normal tissue — addressing a key limitation of prior FOLR1-directed therapies in platinum-resistant ovarian cancer.

A phase 2 controlled human infection trial has found that two doses of WRSs2, a live-attenuated oral vaccine candidate against Shigella sonnei, achieved 89% protection — the highest efficacy reported for any Shigella vaccine candidate — with no serious adverse events, advancing a century-long quest for a licensed vaccine against the diarrheal pathogen.

Innovent Biologics has dosed the first patient in TriadicMM-1, a pivotal phase 3 trial evaluating IBI3003, a GPRC5D/BCMA/CD3 trispecific antibody, for relapsed or refractory multiple myeloma — marking the second trispecific antibody globally to reach pivotal phase 3 development in this setting and the first with independent intellectual property rights in China.

Newly launched Bionyra Pharma has raised $165 million in Series A financing and secured exclusive global rights to two TL1A-targeting biologics from China's TrueLab Biopharmaceutical — an anti-TL1A monoclonal antibody and a TL1A×IL-23p19 bispecific antibody — in a deal worth up to $985 million, positioning the company to compete in an IBD drug class already drawing attention from Merck, Roche, and the Sanofi/Teva partnership.

The FDA has accepted Roche's supplemental BLA for a chemotherapy-free combination of mosunetuzumab (Lunsumio VELO) and polatuzumab vedotin (Polivy) in adults with relapsed or refractory large B-cell lymphoma, based on Phase 3 SUNMO trial data showing a 59% reduction in the risk of disease progression or death compared to standard salvage chemotherapy.
