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.

CNS monoclonal antibody therapies demand rigorous screening and monitoring to ensure patient safety in MS, NMOSD, and Alzheimer disease.

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.

FDA reported that the PRECISION-T trial showed 78% chronic GVHD-free survival at 1 year versus 38.4% with standard transplant and granted the approval to Orca Biosystems, making the therapy the first Treg cell–based therapy in blood cancers.

The European Investment Bank-backed investment establishes a new single-use GMP facility with which Icosagen can support complex protein therapeutics from early discovery through phase 1/2 clinical manufacturing.

The FDA has accepted Sarepta's supplemental New Drug Applications seeking to convert casimersen (Amondys 45) and golodirsen (Vyondys 53) from accelerated to traditional approval in Duchenne muscular dystrophy, with a PDUFA target action date of February 28, 2027, backed by ESSENCE confirmatory trial data and years of real-world evidence.

The FDA has granted priority review to Genentech's sBLA for Enspryng (satralizumab), an IL-6 receptor-targeting monoclonal antibody, as a potential first at-home subcutaneous treatment for thyroid eye disease, based on Phase III SatraGO data showing significant proptosis reduction, with an FDA decision expected by October 15, 2026.

ADC Therapeutics has completed enrollment of 100 patients in the Phase 1b LOTIS-7 trial evaluating loncastuximab tesirine-lpyl plus the bispecific antibody glofitamab in relapsed/refractory diffuse large B-cell lymphoma, with full data expected in Q4 2026 following earlier results showing an 89.8% overall response rate.

52-abstract package includes first reported real-world at-home subcutaneous administration data and phase 2 combination findings with anti-tau antibody.

New York-based biotech enters Nasdaq through JATT II merger, betting IL-13 × IL-18 dual blockade can break the efficacy ceiling in I&I

Lumvoa gains FDA approval for thyroid eye disease, adding an IGF-1R antagonist supported by phase 3 active and chronic TED trials.

MilliporeSigma's Sebastian Arana identifies process characterization gaps, tech transfer complexity, and analytical lag as top CGT manufacturing scale-up barriers at BIO 2026.

At BIO International Convention 2026, Mohit Trikha, PhD, CEO of Kiva Bioscience, discussed why emerging human-based preclinical models may have their greatest impact in predicting drug toxicity and tolerability rather than replacing animal testing outright.

Speaking from the show floor at BIO 2026, Dr Anil Kane, Thermo Fisher Scientific's global head of technical and scientific affairs, details how AI partnerships are accelerating drug development decisions across the CDMO continuum.

As the biologic pipeline diversifies across ADCs, bispecific antibodies, and fusion proteins, formulation science has become the critical discipline bridging molecular complexity and patient-ready therapy.

At BIO 2026, Dr Howard Berman, ReAlta Life Sciences’ CEO, explains how an astrovirus-derived anti-inflammatory peptide targets multiple pathways that drive neonatal hypoxic-ischemic encephalopathy (HIE).

At BIO International Convention 2026, Sabeen Mekan, MD, Vice President of Clinical Development at Zymeworks and panelist for The Next Generation of ADCs: Building Kinder, Gentler Cancer Therapeutics, discusses why safety is becoming an increasingly important differentiator in antibody-drug conjugate development and how biomarker-driven patient selection may help guide future treatment decisions.

At the BIO International Convention 2026, oncology drug development expert Mohit Trikha, PhD, CEO, Kivu Bioscience, discusses the promise and limitations of organoids and other human-based preclinical models, emphasizing the need for stronger validation, cross-functional collaboration, and early regulatory engagement to improve clinical trial success rates.

Dr Wyatt McDonnell, Infinimune CEO and co-founder, posits that translatable, decision-linked single-cell data, and not data volume, are what drive effective therapeutic antibody development in this second segment of an interview at BIO 2026.

Mediar Therapeutics has dosed the first participants in a Phase 1 trial evaluating MTX-439, a first-in-class monoclonal antibody targeting SMOC2 for fibrosis associated with chronic kidney disease. The study marks the company's third anti-fibrotic program to enter clinical development and highlights growing interest in fibrosis-directed biologics.

China's National Medical Products Administration has approved izalontamab brengitecan (iza-bren) for recurrent or metastatic nasopharyngeal carcinoma, making it the first bispecific antibody-drug conjugate to receive regulatory approval anywhere in the world.
