FDA grants Orphan Drug Designation for the PRMT5 inhibitor JBI-778 for the treatment of Glioblastoma Multiforme (GBM)

“JBI-778 is our highly differentiated, substrate competitive PRMT5 inhibitor in development for both systemic and brain tumors with certain genetic signatures. It is the second clinical stage oral drug candidate that has emerged from the TIBEO discovery engine,” said Syed Kazmi, Chief Executive Officer, Jubilant Therapeutics Inc. He further added, “JBI-778’s differentiated profile compared to other PRMT5 inhibitors in development addresses safety issues of first-generation PRMT5 inhibitors.  It also enables a balanced exposure in brain and plasma – for the treatment of GBM and brain metastases along with the systemic disease. We have identified a novel synthetic lethality approach for prospective patient selection in target indications. JBI-778 has already been cleared by the US FDA to initiate clinical trials, which we anticipate to start during the second half of 2023.”
