Inatherys SAS recently presented preclinical data for INA-03, an anti-transferrin receptor (TfR1/CD71) antibody-drug conjugate (ADC), being developed for the treatment of triple-negative breast cancer (TNBC). INA-03 was constructed by conjugating an antimitotic payload (MMAE) to a humanized IgG4 anti-human CD71 antibody using a novel valine-citrulline linker.
Prostate cancer (PC), often referred to as a cold tumor, typically presents a poor immune response, making it difficult for immune-based therapies to be effective. Metastatic castration-resistant PC (mCRPC) presents a highly aggressive phenotype often refractory to systemic treatment.
Antibody-drug conjugates, a well-established antitumor strategy, are used for targeted delivery of cytotoxic drugs through antibodies. As cancer research progresses, other technologies with different mechanisms are advancing in the oncologic pipeline. Researchers from Cybrexa Therapeutics Inc. presented new preclinical data on CBX-15, a peptide-drug conjugate (PDC) consisting of a pH-low insertion peptide (pHLIP) linked to monomethyl auristatin E (MMAE).
Lirum Therapeutics Inc. has presented data regarding their insulin-like growth factor receptor (IGF-1R) antagonist LX-101, which couples an IGF-1 variant to a cytotoxic methotrexate payload. The antitumoral activity of LX-101 was investigated in Ewing sarcoma and desmoplastic small round cell tumor.
Suzhou Ribo Life Science Co. Ltd. recently reported on the development and preclinical characterization of a novel blood-brain barrier (BBB)-penetrating oligonucleotide drug, RBD-8088, for the treatment of glioblastoma.
Ribometrix Inc. recently discussed the discovery and preclinical evaluation of a novel potent and selective eukaryotic translation initiation factor 4E (eiF4E) inhibitor, RBX-6610, being developed for the treatment of KRAS-mutant non-small-cell lung cancer (NSCLC).
CDR-Life Inc. has reported preclinical data for the CDR-813, a novel antibody fragment-based bivalent T-cell engager targeting preferentially expressed antigen in melanoma (PRAME) on HLA-A*02:01.
UL16 binding protein 6 (ULBP6) is a molecule belonging to the stress-induced NKG2D ligand family and its expression is up-regulated on the surface of cancerous cells, binding to the immune-activating NKG2D receptor on natural killer (NK) and T cells, thus promoting immune evasion.
Metastatic solid tumors may be curable now. Among the most profound results presented over the weekend at the European Society for Medical Oncology (ESMO) 2024 Congress were the 10-year data from the Checkmate-067 and Keynote-006 trials, the phase III trials that tested Opdivo (nivolumab, Bristol Myers Squibb Co.) and Keytruda (pembrolizumab, Merck & Co. Inc.) as first-line agents in advanced or metastatic melanoma.
