Belgian pharma giant UCB SA is putting skin in the bispecific T-cell engager (TCE) game, announcing a potential $1.1 billion deal to license Antengene Corp.’s ATG-201. ATG-201 is a CD19/CD3 bispecific TCE antibody aimed at autoimmune disorders, though specific indications were not disclosed.
Bispecific T-cell engagers (TCEs) aim to combat cancer by simultaneously binding T cells and tumor cells in order to induce the first to kill the second. This approach has failed to work effectively against many solid tumors because the exogenous engager proteins do not penetrate into tumors at sufficiently high concentrations.
Nectin-4 is a cell-surface protein that is highly expressed in a variety of solid tumors, including bladder, head and neck, and certain aggressive breast cancers. Its low-level expression in some normal tissues creates a challenge for therapies, which can unintentionally damage healthy cells and trigger severe side effects.
HER2-targeted antibody-drug conjugates (ADCs) have significantly improved cancer therapy in recent decades. However, ADCs can cause toxicity and resistance, while T-cell engagers (TCEs) show promising antitumor activity in solid tumors but are limited by substantial adverse effects.
Nectin-4 is a cell-adhesion molecule that is highly expressed in several malignancies, including bladder, colorectal, lung and breast cancers, while exhibiting minimal expression in most normal adult tissues.
Enara Bio Ltd. is staking a claim to having validated the first in a new class of tumor antigens derived from unannotated regions of the dark genome, describing its findings in talks and posters being presented at the Society of Immunotherapy in Cancer (SITC) meeting in National Harbor, Md., Nov. 5-9, 2025.
T-cell engagers (TCEs) are a new class of immuno-oncology therapies that have proven effective for the treatment of both solid tumors and hematological malignancies. Among validated targets in this field, claudin 18.2 (CLDN18.2) is one of the most clinically established. Researchers from Astrazeneca plc and collaborators reported the preclinical evaluation of AZD-5863, a bispecific fully human monoclonal antibody targeting claudin CLDN18.2 and CD3.
An 85% remissions rate was found in updated results from Aptevo Therapeutics Inc.’s ongoing phase Ib/II Ranier study of mipletamig in one of the toughest blood cancers to treat.
Cullinan Therapeutics Inc. swept up ex-China rights to a multiple myeloma (MM)-targeting BCMAxCD3 bispecific T-cell engager (TCE) velinotamig from Chongqing Genrix Biopharmaceutical Co. Ltd. via a potential $712 million deal June 4. The plan is to repurpose the cancer drug to autoimmune disease.
