Jubilant Therapeutics Inc., a biopharmaceutical Company advancing small molecule precision therapeutics to address unmet medical needs in oncology and autoimmune diseases, today announced U.S. Food and Drug Administration (US FDA) clearance of the Investigational New Drug application (IND) for JBI-778, an oral, brain penetrant and selective protein arginine methyl transferase 5 (PRMT5) inhibitor, for the treatment of solid tumors with brain metastases and primary brain tumors including high-grade glioma.

The Phase I/II trial is an open-label, two-part dose escalation and expansion study designed to define the safety profile, pharmacokinetics, optimal dosing and preliminary activity of JBI-778. The study population in the dose escalation phase will include patients with stable brain metastasis whose disease has failed prior standard therapy. Expansion cohorts will include patients with active brain metastases and high-grade gliomas.

Hari S Bhartia, Chairman, Jubilant Therapeutics Inc. shared on the announcement, “JBI-778 will be our second, highly selective oral drug candidate to enter clinical development following JBI-802. These two programs, along with several others partnered or in preclinical development, highlight Jubilant Therapeutics’ proven discovery engine and structure-based drug discovery expertise.”

Syed Kazmi, Chief Executive Officer, Jubilant Therapeutics Inc. said, “JBI-778 was engineered by our drug discovery team to be a PRMT5 substrate-competitive and brain penetrant drug candidate to address primary brain tumors and brain metastases which currently have limited treatment options. The incidence of brain metastasis is increasing due to improved therapies, increased imaging of neurologically asymptomatic patients and patients living longer. Our team has developed a unique capability to optimize brain penetration for precision oncology therapeutics. In addition to JBI-778, we are also advancing an oral brain penetrant PDL1 inhibitor, JBI 2174, which is on the IND-track to potentially treat primary CNS cancers among others.”
