We investigated panobinostat 40 mg three times weekly in 35 adult patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). Overall response rate and complete response were 17.1% and 11.4%, respectively. Median progression-free survival (PFS) and overall survival were 2.4 and 7.6 months, respectively. Calculated 12, 24 and 36 months PFS were 26%, 11% and 11%, respectively. Four patients who achieved a sustained CR, continued receiving panobinostat for an overall period of 44, 48, 50, 62 months. Thrombocytopenia grade 3 (5 patients) and 4 (24 patients) represented the main toxic effect, causing dose reduction or treatment suspension in 19 patients. Genomic analysis was unable to identify any relationship between mutations and response; TP53 mutation appeared not to impact the clinical outcome. Overall, panobinostat has a modest activity in R/R DLBCL patients, however it can induce very long lasting responses in some cases. Thrombocytopenia frequently limits the use of this agent.

Abstract
We investigated panobinostat 40 mg three times weekly in 35 adult patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). Overall response rate and complete response were 17.1% and 11.4%, respectively. Median progression-free survival (PFS) and overall survival were 2.4 and 7.6 months, respectively. Calculated 12, 24 and 36 months PFS were 26%, 11% and 11%, respectively. Four patients who achieved a sustained CR, continued receiving panobinostat for an overall period of 44, 48, 50, 62 months. Thrombocytopenia grade 3 (5 patients) and 4 (24 patients) represented the main toxic effect, causing dose reduction or treatment suspension in 19 patients. Genomic analysis was unable to identify any relationship between mutations and response; TP53 mutation appeared not to impact the clinical outcome. Overall, panobinostat has a modest activity in R/R DLBCL patients, however it can induce very long lasting responses in some cases. Thrombocytopenia frequently limits the use of this agent.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
