In the last decade, a better understanding of the molecular pathogenesis of B-cell non-Hodgkin lymphomas has resulted in the development of novel targeted therapies, such as small molecule inhibitors of select kinases in the B-cell receptor pathway, antibody–drug conjugates, and small molecules that target a variety of proteins (eg, CD-19, EZH2, and XPO-1–mediated nuclear export). Anti-CD19 CAR T-cell therapy, first approved for relapsed/refractory (R/R) diffuse large B-cell lymphoma, has also emerged as a novel treatment option for R/R follicular lymphoma and mantle cell lymphoma. These NCCN Guideline Insights highlight the new targeted therapy options included in the NCCN Guidelines for B-Cell Lymphomas for the treatment of R/R disease.
In the present retrospective study of data from the SEER-Medicare database, we found that age, health status, race, and socioeconomic status were associated with receipt of MM treatment. These factors have previously been linked to reduced usage of specific treatments for MM, such as stem cell transplantation. To the best of our knowledge, however, ours is the first study to show their association with the receipt of any MM therapy.
Bone disease is the most frequent disease-defining clinical feature of multiple myeloma (MM), with 90% of patients developing bone lesions over the course of their disease. For this reason, imaging plays a major role in the management of disease in patients with MM. Although conventional radiography has traditionally been the standard of care, its low sensitivity in detecting osteolytic lesions has called for more advanced imaging modalities. In this review, we discuss the advantages, indications, and applications of whole-body low-dose CT (WBLDCT), F-fluorodeoxyglucose (FDG)-PET/CT, MRI, and other novel imaging modalities in the management of disease in patients with plasma cell dyscrasias. We also review the state of the art in treatment of MM bone disease (MMBD) and the role of bisphosphonates and denosumab, a monoclonal antibody that binds and blocks the activity of receptor activator of nuclear factor-kappa B ligand (RANKL), which was recently approved by the U.S. Food and Drug Administration for MMBD.
Summary Bendamustine (B) with rituximab (R) is a standard frontline treatment for medically fit follicular lymphoma (FL) patients. The safety and efficacy of maintenance rituximab (MR) after BR induction has not been formally compared to observation for FL, resulting in disparate practice patterns. Prospective trials have shown benefit of MR after R‐CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) or R‐CVP (rituximab, cyclophosphamide, vincristine, prednisone), yet recent data from the GALLIUM study comparing outcomes of patients treated with chemotherapy with R or obinutuzumab (G) showed higher than anticipated fatal adverse events with BR/BG. In order to assess the efficacy and tolerability of MR after BR, we retrospectively collected data on 640 newly diagnosed patients treated with FL. We found that patients who achieved partial remission (PR) after ≥4 cycles of BR had improved duration of response (DOR) with MR vs. no maintenance, whereas those in complete remission did not. These findings were confirmed in a validation cohort. In the entire study population, the known fatal adverse event rate after BR was 2·5% and did not significantly differ in those receiving MR versus no maintenance. [Correction added on 14 January 2019, after online publication: The preceding sentence has been corrected in this current version.] Within the limitations inherent to retrospective analysis, these data suggest that FL patients with a PR to BR experience prolongation of remission with MR with an acceptable safety profile.
Background: Targeted therapies including ibrutinib, acalabrutinib and venetoclax (ven) have fundamentally changed the treatment of patients (pts) with chronic lymphocytic leukemia (CLL) leading to improved outcomes and durable remissions for many pts. However, CLL remains an incurable disease and a subset of pts will ultimately have progressive CLL following treatment with a covalent Bruton's Tyrosine Kinase inhibitor (cBTKi, e.g., ibrutinib, acalabrutinib) and ven. Data on efficacy of therapies for "double exposed" pts (i.e., pts exposed to both a cBTKi and ven) are extremely limited. Available approved options include chemoimmunotherapy (CIT) and phosphatidylinositol 3-kinase inhibitors (PI3Ki). However, the landmark clinical trials leading to the approvals of CIT and PI3Kis did not include pts treated with either cBTKi or ven (Furman et al. NEJM 2014, Flinn et al. Blood 2018). Non-covalent BTKis (ncBTKi) and chimeric antigen receptor (CAR) T-cell therapy have demonstrated promising clinical activity in double exposed CLL pts in clinical trials (Mato et al. Lancet 2021, Siddiqi et al. ASH 2020), but have not yet been compared to other novel agents or CIT in clinical trials or real-world analyses. We sought to describe outcomes of therapies for "double exposed" CLL pts. Methods: A retrospective, international, multicenter study was conducted. CLL pts were included if they received a cBTKi and ven and then a subsequent CLL-directed therapy. Therapies for Richter Transformation were excluded. Investigators identified pts at each site and collected data on demographics, disease characteristics, prior therapies, subsequent therapies and response assessments. Information was collected on up to three subsequent lines of therapy (LOT 1-3) per patient. The primary study endpoint was investigator-assessed overall response rate (ORR) per iwCLL 2018 criteria to therapies (LOT 1-3) following both cBTKi and ven. Kaplan-Meier method was used to estimate progression free survival (PFS). All other analyses were descriptive. Analyses were performed using STATA 17.0. Results: We report outcomes on 125 CLL pts who had prior cBTKi and ven and received a subsequent LOT. Baseline characteristics are presented in Table 1. ORR to prior cBTKi was 84.7% and 69.6% to prior ven. The most common reason for discontinuation of prior cBTKi and ven was CLL progression (71.1% cBTKi, 68.8% ven) followed by toxicity (25.6% cBTKi, 16.8% ven). Most common treatment strategies included ncBTKi (n=45), cBTKi (n=43), CIT (n=23), PI3Ki (n=24), alloSCT (n=17), CAR T-cell therapy (n=9), ven re-treatment (n=6), and other (n=44). ORR for selected agents following cBTKi and ven are presented in Table 2. ORR and PFS estimates were as follows: CAR T-cell therapy (85.7%, median PFS 4 months), alloSCT (76.5%, median PFS 11 months), ncBTKi (75.0%, median PFS not reached), PI3Ki (40.9%, median PFS 5 months), CIT (31.8%, median PFS 3 months) and ven re-treatment (ORR 40%, median PFS 14 months). ORR to cBTKi was 53.7%; however, median PFS for pts who discontinued a previous cBTKi for PD was 1 month versus 7 months for pts who discontinued due to AE. Figure 1 shows Kaplan-Meier estimated PFS for ncBTKi, PI3Ki, alloSCT, and CIT. Conclusions: In the largest series of "double exposed" CLL pts, several key findings warrant further investigation and discussion. Practice patterns are variable and no standard of care exists for CLL pts previously treated with a cBTKi and ven. Additionally, approved standard therapies including CIT combinations and PI3Kis yield poor outcomes with responses which are not durable. The low response rates and short PFS for PI3Ki and CIT call into question the use of these therapies as standard comparator arms in planned randomized trials. At this time, ncBTKi has a high ORR with durable responses (median PFS not reached). There appears to be a promising role for alloSCT in select, fit patients (ORR 76.5%, median PFS 11 months), and CAR T-cell therapy should be further explored in this population (ORR 85.7%, median PFS 4 months). Overall, this study highlights a continued unmet need for therapies for "double exposed" CLL pts. Figure 1 Figure 1.
