Eli Lilly and CompanyPositive Phase 3 results for Jaypirca combination show 45% reduction in disease progression risk, supporting regulatory expansion.

Eli Lilly announced positive results from the Phase 3 BRUIN CLL-322 clinical trial evaluating the addition of Jaypirca to a time-limited venetoclax and rituximab regimen for patients with relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma. The study met its primary endpoint, showing that the pirtobrutinib combination reduced the risk of disease progression or death by 45% compared to the control arm of venetoclax and rituximab alone. The trial enrolled 639 patients, nearly 80% of whom had been previously treated with a covalent BTK inhibitor. At a median follow-up of 27.3 months, the median progression-free survival in the pirtobrutinib arm had not been reached, compared to 39.7 months in the control arm. The safety profile was consistent with the known profiles of the individual medicines, with minimal additive toxicity observed. Eli Lilly plans to submit the data to global regulatory authorities to expand the use of Jaypirca as a potential new standard of care in previously treated CLL/SLL populations.
