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).
