Kenai Therapeutics has completed enrollment in the Phase 1b/2a REPLACE trial of RNDP-001, an allogeneic iPSC-derived dopaminergic neuron replacement therapy for idiopathic Parkinson's disease, with safety and preliminary efficacy data expected in 2027 — representing a significant step toward a potential disease-modifying cell therapy for a condition affecting more than 10 million people worldwide.

LTZ Therapeutics has received FDA IND clearance for LTZ-232, a first-in-class bispecific antibody designed to activate tumor-associated macrophages to phagocytose EpCAM-positive colorectal cancer cells — a novel myeloid-engaging approach aimed at overcoming the immunologically cold tumor microenvironment that has historically limited immunotherapy in this setting.

Biocytogen and Whitehawk Therapeutics have announced a global collaboration combining Biocytogen's RenLite bispecific antibody discovery platform with Whitehawk's CPT113-based ADC linker-payload technology to generate bispecific ADC candidates with differentiated tumor-targeting profiles — with Whitehawk targeting new ADC INDs within 12 to 24 months.

The European Commission has approved Tepkinly in combination with lenalidomide and rituximab for adults with relapsed or refractory follicular lymphoma after at least two prior systemic therapies, based on Phase 3 EPCORE FL-1 data showing a 79% reduction in risk of disease progression or death — marking the first bispecific antibody-based combination regimen approved in Europe for this indication.

Three-year follow-up data from Agenus' Phase 2 trial of botensilimab plus balstilimab in refractory microsatellite-stable metastatic colorectal cancer show a 33% overall survival rate at three years — with evidence of a plateau on the Kaplan-Meier curve beyond two years — representing an unprecedented durability signal in a tumor type historically resistant to immune checkpoint therapy.

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.
