Methods Data used in this study included RNA (n=143) and whole exome (n=126) sequencing data from available FFPE tumor samples at the time of a relapse (any line of treatment, r1-r10 relapse timepoints included in analysis, one per patient), consented to the Molecular Epidemiology Resource (n=61), banked in the Mayo Lymphoma Biobank (n=50), or consented to the CC-122-ST-001 clinical trial (n=32, NCT01421524). In summary, we show for the first time that rrDLBCL patients can be classified into four gene expression clusters that are associated with distinct pathway, TME, and genetic programs. These clusters should now be tested to learn if they can help select patients for newer therapies for rrDLBCL such as CAR-T and bispecific antibodies.

Our results provide a novel role for lineage factors Aiolos and Ikaros in DLBCL as well as further insight into the mechanism(s) of Aiolos and Ikaros mediated transcriptional repression and unique therapeutic combination strategies.

A total of 68 patients were enrolled (DLBCL [n = 27], FL [n = 41; 31 lenalidomide-naïve, 10 lenalidomide-treated]). Avadomide plus rituximab was well tolerated, and preliminary antitumor activity was observed in patients with R/R DLBCL and FL, including subgroups with typically poor outcomes. These results support further investigation of novel CELMoD agents in combination with rituximab in R/R DLBCL and FL.

CC-122 plus rituximab was well tolerated, with preliminary antitumor activity in patients with R/R DLBCL. This innovative study demonstrates the feasibility of assessing the tolerability and preliminary efficacy of novel combinations utilizing a multi-arm dose-finding design.

Compared with existing agents targeting Ikaros/Aiolos that show activity in hematologic malignancies, such as lenalidomide, avadomide, and iberdomide (CC-220), CC-99282 induced a more rapid, deep, and sustained degradation of Ikaros/Aiolos, causing derepression of cyclin-dependent kinase (CDK) inhibitors and interferon-stimulated genes ( IRF7 , IFIT3 , and DDX58 ), and the reduction of the highly critical oncogenic factors c-Myc and IRF4...In addition, CC-99282 acts synergistically in combination with anti-CD20 monoclonal antibody treatment. Collectively, these data support the clinical investigation of CC-99282 as monotherapy and in combination with rituximab in patients with R/R NHL.

Additionally, we generated a disease-specific virtual patient population to represent the variability in patient characteristics and response to treatment observed for a diffuse large B-cell lymphoma trial cohort. Model utility was demonstrated by simulating the avadomide effect in the virtual population for various dosing schedules and determining the incidence of high-grade neutropenia, its duration, and the probability of recovery to low-grade neutropenia.

Furthermore, knockout of AMBRA1 renders resistance to CC-122 in SU-DHL-4 and U-2932, whereas knockout of RFX7 leads to resistance specifically in SU-DHL-4. The ubiquitous and cell line-specific mechanisms of CC-122 resistance in DLBCL cell lines revealed in this work pinpoint genetic alternations that are potentially associated with clinical resistance in patients and facilitate the development of biomarker strategies for patient stratification, which may improve clinical outcomes of patients with R/R DLBCL.

While patients with R/R NHL tend to have poor prognoses, agents mediating Ikaros/Aiolos degradation, such as lenalidomide (LEN) and avadomide (AVA), have shown promise in the R/R NHL setting... CC-99282 demonstrated potent autonomous cell killing and apoptosis in DLBCL cells, independent of the origin subtype, presence of high-risk chromosomal translocations, or acquired resistance to doxorubicin... CC-99282 is a novel CELMoD that, compared with LEN and other immunomodulatory agents, shows enhanced antiproliferative, apoptotic, and immune-stimulatory activity in a range of DLBCL models, including those with acquired chemoresistance. These data support the clinical investigation of CC-99282 in patients with R/R NHL.

While the results of early phase investigations involving ibrutinib and the IMiD agents, lenalidomide, pomalidomide, as well as avadomide, strongly support the hypothesis that the B-cell receptor (BCR) pathway, involving MYD88 and CD79B and NF-kB activation, is critical to the pathogenesis of PCNSL, much work is needed to elucidate mechanisms of resistance. Similarly, development of strategies to overcome immunosuppressive mechanisms that are upregulated in the tumor microenvironment is a high priority. Finally, ongoing evidence supports the hypothesis that the blood-brain barrier represents a significant impediment to efficient brain tumor penetration of novel therapeutic agents and innovative strategies of drug delivery remain essential to further improve outcomes.

Pts with early relapse (ER) (progressive disease <2 y after initial diagnosis) and those who are double-refractory (DR) to both rituximab and chemotherapy, have particularly poor outcomes. Conclusions : Long-term follow-up results demonstrate that avadomide plus obinutuzumab has a manageable safety profile and durable responses in patients with R/R FL. The antitumor activity of cereblon modulators plus next-generation anti-CD20 antibodies in heavily pretreated R/R NHL warrants further investigation as a novel chemotherapy-free option.

Avadomide (CC-122) is a novel cereblon-binding agent that exhibits antilymphoma and immune-modulation activities with a biological profile distinct from similar agents, such as lenalidomide. Avadomide dose intensity was consistent across cohorts and the 3-mg dose given 5 consecutive days/week was established as the RP2D. This phase I study identified a tolerable dose of avadomide, with an acceptable toxicity profile and clinically meaningful efficacy in Japanese patients with previously treated NHL.

Notably, clinical analyses showed increased PD-L1 expression on T cells, as well as intratumoral expression of chemokine signaling genes in B cell malignancy patients receiving avadomide-based therapy. These data illustrate the importance of overcoming a low inflammatory T cell state to successfully sensitize CLL to checkpoint blockade-based combination therapy.

Avadomide plus obinutuzumab has a manageable toxicity, being a tolerable treatment option for most patients. Although the prespecified threshold for activity was not met in the trial, we believe that the preliminary antitumour activity of cereblon modulators plus next-generation anti-CD20 antibodies in heavily pretreated relapsed or refractory non-Hodgkin lymphoma warrants further investigation as a chemotherapy-free option in this setting.

However, previous genomic studies of relapsed and/or refractory DLBCL (rrDLBCL) are limited by small sample sizes and much less is known about the genomic landscape or the changes in clonal populations that occur within a patient undergoing R-CHOP therapy...The second cohort consisted of 75 FFPE samples from 2 rrDLBCL clinical trials CC-122-ST-001 and CC-122-DLBCL-001 (NCT01421524 and NCT02031419)... Here we report to our knowledge the largest genomic dataset in relapsed and /or refractory DLBCL using tumor biopsies. Previously identified mutated genes in rrDLBCL were confirmed and novel drivers identified. Paired samples analysis reveals clonal shifts which occur during treatment and at time of relapse.
