Eli Lilly oncology unit gets USFDA nod for Jaypirca to treat mantle cell lymphoma
MCL is a rare blood cancer and a form of non-Hodgkin lymphoma.;
Indianapolis: Loxo@Lilly, the oncology unit of Eli Lilly and Company, has announced that the U.S. Food and Drug Administration (FDA) has approved Jaypirca (pirtobrutinib, 100 mg & 50 mg tablets) for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a Bruton's tyrosine kinase (BTK) inhibitor. Jaypirca was approved under the FDA's Accelerated Approval pathway based on response rate from the open-label, single-arm, international, Phase 1/2 study, called the BRUIN trial. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
Jaypirca, a highly selective kinase inhibitor, utilizes a novel binding mechanism and is the non-covalent (reversible) BTK inhibitor. Jaypirca can reestablish BTK inhibition in MCL patients previously treated with a covalent BTK inhibitor (ibrutinib, acalabrutinib, or zanubrutinib) and extend the benefit of targeting the BTK pathway.
"The approval of Jaypirca represents an important advance for patients with relapsed or refractory MCL, who currently have limited options and historically have had a poor prognosis following discontinuation of treatment with a covalent BTK inhibitor," said Michael Wang, M.D., Puddin Clarke Endowed Professor of Lymphoma and Myeloma at The University of Texas MD Anderson Cancer Center. "These data indicate that Jaypirca can provide efficacy in patients previously treated with a covalent BTK inhibitor, potentially extending the time patients may benefit from BTK inhibition therapy. Jaypirca offers a new approach to targeting the BTK pathway following treatment with a covalent BTK inhibitor and has the potential to meaningfully impact the treatment paradigm for relapsed and refractory MCL patients."
