Lenalidomide plus R-GDP (R2-GDP) in relapsed/refractory diffuse large B-cell lymphoma: Final results of the R2-GDP-GOTEL trial.

 

Abstract No : 8019

Abstract Type : Oral Abstract Session

Indication : Diffused Large B-Cell Lymphoma (DLBCL)

Intervention : Lenalidomide

Company : CELGENE

Technology : Small molecule

 

Results:

79 pts were enrolled between April 2015 and September 2018. Median age was 70 years (range 23-86), 48,7% women. 78 pts were considered for efficacy and safety in the intention to treat (ITT) analysis. With a median follow-up of 13 months at the time of cut-off (November 2019), ORRwas 59.0%, with 32.1% complete responses (CR) and 26.9% partial responses (PR). In the primary refractory population (n = 33), ORR was 45.5%, with 21.2% CR and 24.3% PR. There were no statistically significant differences in ORR with respect to COO. In Double-Hit R/R DLBCL (n = 16), ORR was 37.5% with 25% CR. Median OS was 12.0 months (6.9-17.0). Most common grade 3/4 (G3/4) adverse events were thrombocytopenia (60.2%), neutropenia (60.2%) and anemia (26.9%). Febrile neutropenia occurred in 14.1% pts. Most frequent non-hematologic G3/4 events were asthenia (19.2%), infection (15.3%) and renal insufficiency (6.4%). There were 4 toxic deaths related to the R2-GDP schedule.

 

Conclusion:

LEN with Rituximab and GDP (R2-GDP) is feasible and active in R/R DLBCL. Results in the primary refractory DLBCL population are particularly promising. Analysis of COO did not revealed differences in response rates. Immune biomarkers results will be showed at the meeting.

 

Commentary:

Promising results in primary refractory DLBCL patients irrespective of the cell of origin.
