ROBUST: Lenalidomide-R-CHOP versus placebo-R-CHOP in previously untreated ABC-type diffuse large B-cell lymphoma.

ABSTRACT: Activated B-cell-like (ABC) diffuse large B-cell lymphoma (DLBCL), the major constituent of nongerminal center B-cell-like (non-GCB) DLBCL, is associated with poorer survival outcomes than GCB-type DLBCL. In Phase II studies, lenalidomide combined with R-CHOP (R(2)-CHOP) improved outcomes relative to historical R-CHOP in newly diagnosed DLBCL, particularly in non-GCB cases. ROBUST (CC-5013-DLC-002) is a randomized, double-blind, global, Phase III study of oral lenalidomide (15 mg, days 1-14) plus R-CHOP21 × 6 versus placebo-R-CHOP21 × 6 in patients with previously untreated ABC-type DLBCL. Subtyping is done within 3 calendar days by central laboratory gene-expression profiling of formalin-fixed paraffin-embedded biopsy tissue. The primary end point is progression-free survival. Secondary end points include response rates, overall survival and health-related quality of life.

Project description:BackgroundOutcomes with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) or CHOP-like chemotherapy in peripheral T-cell lymphoma are poor. We investigated whether the regimen of gemcitabine, cisplatin, and methylprednisolone (GEM-P) was superior to CHOP as front-line therapy in previously untreated patients.MethodsWe did a phase 2, parallel-group, multicentre, open-label randomised trial in 47 hospitals: 46 in the UK and one in Australia. Participants were patients aged 18 years and older with bulky (tumour mass diameter >10 cm) stage I to stage IV disease (WHO performance status 0-3), previously untreated peripheral T-cell lymphoma not otherwise specified, angioimmunoblastic T-cell lymphoma, anaplastic lymphoma kinase-negative anaplastic large cell lymphoma, enteropathy-associated T-cell lymphoma, or hepatosplenic γδ T-cell lymphoma. We randomly assigned patients (1:1) stratified by subtype of peripheral T-cell lymphoma and international prognostic index to either CHOP (intravenous cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and vincristine 1·4 mg/m2 [maximum 2 mg] on day 1, and oral prednisolone 100 mg on days 1-5) every 21 days for six cycles; or GEM-P (intravenous gemcitabine 1000 mg/m2 on days 1, 8, and 15, cisplatin 100 mg/m2 on day 15, and oral or intravenous methylprednisolone 1000 mg on days 1-5) every 28 days for four cycles. The primary endpoint was the proportion of patients with a CT-based complete response or unconfirmed complete response on completion of study chemotherapy, to detect a 20% superiority of GEM-P compared with CHOP, assessed in all patients who received at least one cycle of treatment and had an end-of-treatment CT scan or reported clinical progression as the reason for stopping trial treatment. Safety was assessed in all patients who received at least one dose of study medication. This trial is registered with ClinicalTrials.gov (NCT01719835) and the European Clinical Trials Database (EudraCT 2011-004146-18).FindingsBetween June 18, 2012, and Nov 16, 2016, we randomly assigned 87 patients to treatment, 43 to CHOP and 44 to GEM-P. A planned unmasked review of efficacy data by the independent data monitoring committee in November, 2016, showed that the number of patients with a confirmed or unconfirmed complete response with GEM-P was non-significantly inferior compared with CHOP and the trial was closed early. At a median follow-up of 27·4 months (IQR 16·6-38·4), 23 patients (62%) of 37 assessable patients assigned to CHOP had achieved a complete response or unconfirmed complete response compared with 17 (46%) of 37 assigned to GEM-P (odds ratio 0·52, 95% CI 0·21-1·31; p=0·164). The most common adverse events of grade 3 or worse in both groups were neutropenia (17 [40%] with CHOP and nine [20%] with GEM-P), thrombocytopenia (4 [10%] with CHOP and 13 [30%] with GEM-P, and febrile neutropenia (12 [29%] with CHOP and 3 [7%] with GEM-P). Two patients (5%) died during the study, both in the GEM-P group, from lung infections.InterpretationThe number of patients with a complete response or unconfirmed complete response did not differ between the groups, indicating that GEM-P was not superior for this outcome. CHOP should therefore remain the reference regimen for previously untreated peripheral T-cell lymphoma.FundingBloodwise and the UK National Institute of Health Research.

Project description:BackgroundRituximab (R) plus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) is the current standard therapy for diffuse large B cell lymphoma (DLBCL). Obinutuzumab (G), a glycoengineered, type II anti-CD20 monoclonal antibody, has shown activity and an acceptable safety profile when combined with CHOP (G-CHOP) in patients with advanced DLBCL. We present the final analysis results of the Phase III GOYA study (NCT01287741), which compared the efficacy and safety of G-CHOP versus R-CHOP in patients with previously untreated DLBCL.MethodsPatients aged ≥ 18 years with previously untreated advanced DLBCL were randomly assigned to receive eight 21-day cycles of R or G, plus six or eight cycles of CHOP. The primary endpoint was investigator-assessed progression-free survival (PFS). Secondary endpoints included overall survival, other time-to-event endpoints, and safety; investigator-assessed PFS by cell of origin subgroup was an exploratory endpoint.ResultsA total of 1418 patients were randomized, with 1414 included in this final analysis (G-CHOP, N = 704; R-CHOP, N = 710). Five-year PFS rates were 63.8% and 62.6% for G-CHOP and R-CHOP, respectively (stratified hazard ratio 0.94, 95% CI 0.78-1.12; p = 0.48). The results of the secondary efficacy endpoints did not show a benefit of G-CHOP over R-CHOP. In the exploratory analysis, a trend towards benefit with G-CHOP over R-CHOP was apparent in the patients with germinal center B cell DLBCL. The safety profile of G-CHOP was as expected, and no new safety signals were observed. More grade 3-5 (75.1% vs 65.8%), serious (44.4% vs 38.4%), and fatal (6.1% vs 4.4%) adverse events (AEs) were observed in the G-CHOP arm compared with the R-CHOP arm, respectively, with the most common fatal AEs being infections. A higher incidence of late-onset neutropenia occurred in the G-CHOP arm (8.7%) versus the R-CHOP arm (4.9%).ConclusionsThe final analysis, similar to the primary analysis, did not show a PFS benefit of G-CHOP over R-CHOP in previously untreated patients with DLBCL. The results of the secondary endpoints were consistent with the primary endpoint. Further exploratory analyses and investigation of biomarkers are ongoing.
