Cybrexa Therapeutics, a biotechnology company developing a new class of cancer therapeutics through its alphalex™ tumor targeting platform, today announced that the FDA- and EMA-approved poly ADP-ribose polymerase (PARP) inhibitor rucaparib (marketed as Rubraca®) is conjugated in lead candidate CBX-11 (alphalex™-rucaparib). The first set of preclinical data supporting CBX-11 demonstrate that Cybrexa’s proprietary alphalex™ platform can enable full dose administration with DNA damaging chemotherapy, creating synergistic efficacy in destroying solid tumors independent of homologous recombination deficiency (HRD) status. In particular, CBX-11 selectively delivers rucaparib to tumor tissue, avoiding the bone marrow toxicity that has prevented optimal dosing of DNA damaging chemotherapy in combination with PARP inhibitors.
These data were exhibited today in a poster presentation by Vishwas Paralkar, PhD, Chief Scientific Officer of Cybrexa, during the American Association for Cancer Research (AACR) Annual Meeting 2019.
“These mark the first results demonstrating that combination of the potent PARP inhibitor rucaparib and ...
