Lilly Gets Accelerated Approval for Lymophoma Drug
FDA has granted Eli Lilly accelerated approval for Jaypirca (pirtobrutinib) for treating relapsed or refractory mantle cell lymphoma (MCL) patients who have had at least two lines of systemic therapy, including a BTK inhibitor. Approval was based on data from the BRUIN (NCT03740529) single-arm trial of pirtobrutinib monotherapy in 120 patients with MCL previously treated with a BTK inhibitor, according to an agency release. The overall response rate was 50%, with a complete response rate of 13%, it says, adding that the estimated median duration of response (DoR) was 8.3 months, and the estimated DoR rate at six months was 65.3%.
On the safety side, the most common adverse reactions in patients with MCL were fatigue, musculoskeletal pain, diarrhea, edema, dyspnea, pneumonia, and bruising,” FDA says. “Grade 3 or 4 laboratory abnormalities in greater than or equal to 10% of patients were decreased neutrophil counts, lymphocyte counts, and platelet counts,” it adds. Additionally, the prescribing information includes warnings and precautions for infections, hemorrhage, cytopenias, atrial fibrillation and flutter, and second primary malignancies.
