In recent years, the introduction of immune checkpoint inhibitors to the oncolytic pipeline has been a significant breakthrough in cancer treatment, but unfortunately some tumors respond only minimally. Besides CTLA-4, and since the approval of PD-1/PD-L1 inhibitors, only the anti-LAG3 strategy (relatlimab, Bristol Myers Squibb Co.) has been good enough to reach the market. In a session dealing with emerging checkpoints beyond PD-1, CTLA-4 and LAG3, Drew Rasco from the START Center for Cancer Care depicted a new player on the ground of immunotherapeutic options.
Duality Biologics (Suzhou) Co. Ltd. has synthesized antibody-drug conjugates comprising anti-GPC3 antibodies covalently linked to exatecan derivatives through a linker. They are reported to be useful for the treatment of cancer.
Sotio Biotech AS, a company owned by PPF Group, has entered into a license and option agreement with Synaffix BV, a Lonza company, to develop next-generation antibody-drug conjugates (ADCs) for the treatment of solid tumors.
Medilink Therapeutics (Suzhou) Co. Ltd. has entered into a strategic research collaboration and worldwide license agreement with Biontech SE for the development of a next-generation antibody-drug conjugate candidate (ADC) against HER3.
Researchers from Panolos Bioscience Inc. and affiliated organizations have published preclinical data for PB-101, a novel glycosylated decoy protein targeting both vascular endothelial growth factor (VEGF) and placental growth factor (PlGF).
Sparx Group has formed a strategic alliance with Arovella Therapeutics Ltd. for the development of a CLDN18.2-chimeric antigen receptor (CAR)-invariant natural killer T (iNKT) cell therapy.
Recurrent driver mutations in FMS-related receptor tyrosine kinase 3 (FLT3) occur in around one-third of patients with de novo acute myeloid leukemia (AML). Although most FLT3 mutations are secondary events in leukemogenesis, they are associated with accelerated clonal expansion and disease progression, and treatment with the tyrosine kinase inhibitor midostaurin has been shown to increase patients’ long-term survival. However, the efficacy of FLT3 inhibitors in eliminating FLT3-mutated clones is variable.
Finding suitable antigens for immunotherapy of myeloid malignancies, particularly acute myeloid leukemia (AML), is an urgent clinical need. Most AML candidate targets, including CD123, are co-expressed by hematopoietic stem and progenitor cells (HSCPs), with the subsequent risk of myelosuppression associated with myeloid cell-targeted chimeric antigen receptor (CAR) T therapy.
The structures of the majority of PD-1/PD-L1 inhibitors currently in use are derived from the arylmethylamine/biphenyl scaffold. Researchers from Southern Medical University reported on the discovery and preclinical evaluation of a novel series of non-arylmethylamine-based PD-1/PD-L1 inhibitors for use in cancer immunotherapy.
