Several STING agonists have demonstrated antitumor efficacy in preclinical studies and are currently under clinical development. However, systemic administration of STING agonists may have adverse effects, while intratumoral injection is limited by tumor accessibility. Therefore, systemic delivery of STING agonists specifically targeted to tumors emerges as a potential strategy to overcome these limitations.

CD40-targeting therapies have been proposed as an interesting alternative to overcome resistance to immune checkpoint inhibitors. In particular, bispecific CD40 antibodies can target CD40 more efficiently and safely than monospecific therapies. In a recent publication, researchers at Alligator Bioscience AB and collaborators demonstrate that bispecific antibodies targeting CD40 and tumor-associated antigens (TAA) can enhance priming of tumor-specific T cells in vivo.

The California Institute for Regenerative Medicine (CIRM) has awarded Calidi Biotherapeutics Inc. a US$3.1 million grant to support continued development of the company's Supernova-1 (SNV-1) preclinical program through IND application. The grant was awarded to Calidi to support IND-enabling studies, finalize manufacturing and the completion of Calidi's IND application for the SNV-1 program.

Treatment with anti-CD19 bispecific T-cell engager and CAR T therapies can lead to T-cell exhaustion and treatment failure. Novartis AG’s first-in-class anti-CD19, anti-CD3 and anti-CD2 IgG-like trispecific antibody PIT-565, which engages CD19+ on tumor cells, and CD3 (TCR signaling component) and CD2 (a costimulatory receptor) on T cells simultaneously to redirect T-cell cytotoxicity toward CD19-positive malignant B cells, has been designed to avoid T-cell exhaustion.

Ovarian cancer is ordinarily associated with poor survival; patients diagnosed with high-grade serous ovarian carcinoma (HGSC) have an overall survival of about 40% at 5 years and 15% at 10 years. Despite having similar histologic features, HGSC patients often experience highly variable outcomes and the underlying determinants for long-term survival (LTS) are largely unknown. In a study published online in Nature Genetics, a multi-institutional group of researchers tried to determine the molecular differences that drive LTS in patients with HGSC.

1st Biotherapeutics Inc. has received clearance from the FDA for its IND application to evaluate FB-849, a small-molecule hematopoietic progenitor kinase 1 (HPK1) inhibitor, in patients with advanced solid tumors.

Onchilles Pharma Inc. has nominated its first drug development candidate, N-17350, a first-in-class biologic therapeutic that is designed to leverage the immunobiology of neutrophils against a wide range of cancer types. Research published last year first described a pathway where human neutrophils release catalytically active neutrophil elastase, called ELANE, to selectively kill many cancer cell types while sparing noncancer cells.
