Defects in antigen presentation lead to resistance to cancer immunotherapy, where type I conventional dendritic cells (cDC1s) are crucial drivers of antitumor immunity and their presence is tied to favorable responses and better outcomes. Intratumoral delivery of adenoviral vector, Ad5-PIB, encoding PU.1, IRF8 and BATF3 reprograms tumor cells into cDC1-like antigen-presenting cells and has shown synergy with immune checkpoint blockade (ICB) therapy at exerting antitumor immunity. Asgard Therapeutics AB has developed AT-108, a lead candidate developed for durable efficacy.

Umoja Biopharma Inc. performed preclinical studies to evaluate the antitumor activity of UB-VV500, an off-the-shell lentiviral vector CAR T-cell product. It is based on its Vivovec technology and designed to engineer fully human anti-B-cell maturation antigen (BCMA)/G protein-coupled receptor class C group 5 member D (GPRC5D) dual-targeting chimeric antigen receptor (CAR) T cells, for the potential treatment of multiple myeloma (MM).

Shanghai Henlius Biotech Inc.’s HLX-3902, a trispecific antibody targeting STEAP1xCD3xCD28, has received approval from the Human Research Ethics Committee (HREC) in Australia and has been filed with the Therapeutic Goods Administration (TGA). The T-cell engager is intended for the treatment of metastatic castration-resistant prostate cancer and other advanced solid tumors.

The discovery of a second-generation dual oral inhibitor of PARP1/2 and tankyrase, JPI-547 (Onconic Therapeutics Inc.), exhibited antitumor activity in HR-deficient xenograft models.

Pancreatic ductal adenocarcinoma (PDAC) is still a highly lethal cancer with limited therapeutic options. Its lethality mainly stems from activating KRAS mutations and a metabolic dependence on nicotinamide adenine dinucleotide (NAD). Researchers from Remedy Plan Inc. have presented data on RPT-E-037, which exerts dual targeting of NAD metabolism through Nampt inhibition and KRAS signaling inhibition using a pan-RAS inhibitor (RMC-6236).
