A new mRNA and lipid nanoparticle (mRNA-LNP) platform could selectively reprogram in vivo cytotoxic effector T cells (Teff), the cells responsible for eliminating infected or tumor cells. To achieve this, scientists at the University of Pennsylvania conjugated LNPs with fractalkine, a molecule that binds to the CX3CR1 receptor, which is a marker of Teff cells. Using this strategy, the researchers delivered an mRNA encoding new proteins such as IL‑2 or human CD62 L‑selectin, opening the door to temporarily reprogramming these cells within the body, both in the blood and in lymphoid tissue, where they reside and become activated.
The interleukin-1 receptor accessory protein (IL1RAP) is expressed in cancer cells within the tumor microenvironment of several cancer types and plays a role in tumor development. DXP-106 is a humanized monoclonal antibody developed by Singlomics Biopharmaceuticals Co. Ltd. that binds to a unique epitope of IL1RAP domain 2 that competes with cytokines.

Shanghai Ailux Biotechnology Co. Ltd. has patented new antibody-drug conjugates consisting of an antibody targeting fibroblast growth factor receptor 2 isoform 2 (FGFR2; FGFR2b) covalently linked to a cytotoxic drug intended for use in the treatment of cancer.
Researchers from Takeda Pharmaceutical Co. Ltd. detailed the preclinical characterization of TAK-188, a first-in-class anti-CCR8 antibody-drug conjugate (ADC) designed to selectively target CCR8+ Tregs, alleviating immunosuppression in the tumor microenvironment.
Biolojic Design Ltd. has reported preclinical data for its antibody-drug conjugate (ADC) BD-200, developed using an AI-guided antibody engineering platform named Multibody.
Harbour Biomed has gained IND clearance from the FDA for HBM-7004, enabling the initiation of a first-in-human phase I trial in subjects with advanced solid tumors.
Arrivent Biopharma Inc. has obtained IND clearance from the FDA for ARR-002 (AV-P138-ADC), an antibody-drug conjugate (ADC) with an initial focus in ovarian and endometrial cancers and broader therapeutic potential across solid tumors. A phase I trial is expected to open in the second half of the year.
Atara Biotherapeutics Inc.’s allogeneic T-cell immunotherapy, Ebvallo (tabelecleucel), for Epstein-Barr virus-positive post-transplant lymphoproliferative disease isn’t out of the running yet. Despite grim predictions in the wake of the U.S. FDA’s second complete response letter for the drug in January, Atara and partner Pierre Fabre Pharmaceuticals Inc. reached agreement with the regulator on a path for resubmitting the BLA.
Biosion Inc. recently presented preclinical data describing their B7H3/PD-L1 bispecific antibody-drug conjugate (ADC) BSI-737 for the treatment of cancer.
