Abstract Multiple tumor types overexpress Nectin-4 and the antibody–drug conjugate (ADC), enfortumab vedotin (EV) shows striking efficacy in clinical trials for metastatic urothelial cancer, which expresses high levels of Nectin-4, validating as a target toxin delivery this indication. Despite excellent data little are reported EV other expressing tumors therapy can produce significant toxicities many patients, frequently leading to discontinuation treatment. Thus, additional approaches with...
DOT1L is a protein methyltransferase involved in the development and maintenance of MLL-rearranged (MLL-r) leukemia through its ectopic methylation histones associated with well-characterized leukemic genes. Pinometostat (EPZ-5676), selective inhibitor DOT1L, clinical relapsed/refractory acute patients harboring rearrangements MLL gene. The observation responses subsequent relapses adult trial treating MLL-r motivated preclinical investigations into potential mechanisms pinometostat...
8515 Background: MM often presents at an advanced stage with a median survival of ~1 year. Treatments are limited; none clearly improve in second-line. In 40–60% patients (pts) BRCA1 associated protein 1 (BAP1) is inactive and linked to dependency on EZH2 (enhancer zeste-homolog 2). regulates gene expression prevent differentiation stem progenitor cells, aberrant activity implicated as oncogenic driver. Tazemetostat, potent, selective, oral inhibitor demonstrated clinical other malignancies;...

PURPOSE BT5528 is a Bicycle Toxin Conjugate, novel class of chemically synthesized molecules, comprising bicyclic peptide targeting EphA2 tumor antigen, linked to cytotoxin (monomethyl auristatin E [MMAE]). overexpressed in many solid tumors and contributes oncogenesis, tumor-associated angiogenesis, metastasis. MATERIALS AND METHODS The primary objectives were investigate the safety tolerability define maximum-tolerated dose, if observed, recommended phase II dose (RP2D)/expansion dose....
Background CD137 (4-1BB) is an immune costimulatory receptor with high therapeutic potential in cancer. We are creating tumor target-dependent agonists using a novel chemical approach based on fully synthetic constrained bicyclic peptide ( Bicycle® ) technology. Nectin-4 overexpressed multiple human cancers that may benefit from agonism. To this end, we have developed BT7480, novel, first-in-class, Nectin-4/CD137 Bicycle tumor-targeted cell agonist™ TICA™). Methods and co-expression analyses...
TPS3655 Background: BT5528 is a Bicycle Toxin Conjugate (BTC), comprising bicyclic peptide targeting the tumor antigen EphA2, linked to cytotoxin (monomethyl auristatin E [MMAE]) via microenvironment cleavable linker. Bicycles are novel class of chemically synthesized constrained peptides, developed by Therapeutics. EphA2 reported be overexpressed in range solid tumors, contributes oncogenesis, tumor-associated angiogenesis and metastasis. Intracellular signaling converges on pathways that...
TPS2668 Background: BT8009 is a Bicycle Toxin Conjugate (BTC), novel class of chemically synthesized molecules, comprising bicyclic peptide targeting Nectin-4 tumor antigen, linked to cytotoxin (monomethyl auristatin E [MMAE]) via valine-citrulline (val-cit) cleavable linker. Nectins (Nectin-1, -2, -3, and -4) nectin-like molecules (Necl) are Ca2+ independent immunoglobulin-like cell adhesion molecules. Recent studies have shown the importance in several human cancers, including lung,...
Abstract Introduction: Clinical studies in cancer patients have validated CD137 agonism as an activator of the immune system to enable tumor rejection. We demonstrated that small, chemically synthetic bicyclic peptides can drive tumor-localized and anti-tumor immunity mouse models. Here, we report next stage our work - delving into mechanism action these novel agents extending program serve whose tumors express EphA2. Experimental Procedures: MultiOmyx™ hyperplexed immunofluorescence assay...
