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.

The biopharmaceutical landscape grows increasingly complex, and competition for experienced engineering talent has intensified accordingly. For professionals with advanced expertise, evaluating potential employers involves assessing innovation capabilities, organizational culture, career trajectory opportunities, and tangible contributions to healthcare advancement.
