Trial Summary

What is the purpose of this trial?

This correlative study aims to understand the pharmacodynamic effects and clonal dynamics in response to epcoritamab by obtaining and analyzing lymph node, bone marrow, and blood samples from subjects enrolled in GCT3013-03 trial sponsored by Genmab at NIH. Samples will be collected before and at multiple time points during treatment with epcoritamab. National Heart, Lung, and Blood Institute (NHLBI) investigators are experienced in testing samples treated with bsAb2,3 including epcoritamab in an ongoing pre-clinical collaboration with Genmab. Addressing the objectives of this correlative study will advance the science and clinical application of epcoritamab specifically as well as T-cell engaging bsAb in general as an emerging class of immunotherapy for cancer. The study is enrolling by invitation only.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Epcoritamab for treating Chronic Lymphocytic Leukemia and Richter Syndrome?

While there is no direct data on Epcoritamab for Richter Syndrome, novel immunotherapies, including those targeting immune checkpoints like PD1, have shown promise in treating this condition. Additionally, therapies effective in CLL, such as those targeting BCR or BCL2, are being evaluated for Richter Syndrome, suggesting potential for Epcoritamab, which is a type of immunotherapy.12345

What makes the drug Epcoritamab unique for treating Richter Syndrome?

Epcoritamab is unique because it is a bispecific antibody that targets both CD3 on T-cells and CD20 on B-cells, potentially offering a novel mechanism of action compared to traditional chemotherapy, which is often ineffective for Richter Syndrome.12346

Richter Transformation in Chronic Lymphocytic Leukemia: Update in the Era of Novel Agents. [2021]Richter transformation (RT) is a poorly understood complication of chronic lymphocytic leukemia (CLL) with a dismal prognosis. It is associated with a switch in histopathology and biology, generally with a transformation of the original CLL clone to diffuse large B-cell lymphoma (DLBCL) or less frequently to Hodgkin's variant of Richter transformation (HVRT). It occurs in 2-10% of CLL patients, with an incidence rate of 0.5-1% per year, and may develop in treatment-naïve patients, although it is more common following therapy. In recent years, there has been a deeper understanding of the molecular pathogenesis of RT that involves the inactivation of the TP53 tumor suppressor gene in 50-60% of cases and the activation of aberrations of NOTCH1 and MYC pathways in about 30% of cases. Compared to the preceding CLL, 80% of cases with DLBCL-RT and 30% of HVRT harbor the same IGHV-D-J rearrangements, indicating a clonal evolution of the disease, while the remaining cases represent de novo lymphomas that are clonally unrelated. Despite advances in understanding the molecular variations and the pathogenesis of the disease, there is still no significant improvement in patient outcomes. However, if no clinical trials were designed for patients with RT in the past, now there many studies for these patients that incorporate new drugs and novel combinations that are being explored. In this review, we summarize the new information accumulated on RT with special emphasis on results involving the novel therapy tested for this entity, which represents an unmet clinical need.
Richter transformation-is there light at the end of this tunnel? [2023]Richter transformation (RT) represents an uncommon (2% to 10%) but feared complication of chronic lymphocytic leukemia (CLL). The disease is characterized by rapid disease kinetics, a high-risk genetic mutational profile, chemoimmunotherapy resistance, and consequent poor survival. The typical overall survival (OS) from the pre-Bruton tyrosine kinase (BTK)/B-cell lymphoma 2 (BCL2) inhibitor CLL era is 6-12 months, and recent series of RT complicating progression on a BTK or BCL2 inhibitor in heavily pretreated relapsed CLL patients suggests an OS of only 3-4 months. Despite these sobering survival statistics, novel agents have the potential to impact the natural RT disease course. This article reviews recent therapeutic developments, focusing on inhibitors of BTK, BCL2, the PD1-PDL1 axis, and T-cell-activating/engaging therapies. Herein, I discuss the importance of randomized clinical trials in a disease where small single-arm studies dominate; industry engagement, including the role of registrational studies; and the need to integrate prospectively planned correlative biological studies embedded within future clinical trials to help discover which patient benefits most from each class or combination of novel targets.
An update for Richter syndrome - new directions and developments. [2022]High-grade transformation of chronic lymphocytic leukaemia [Richter syndrome (RS)] is rare and represents a unique and uncommon clinical challenge. Clonally related diffuse large B cell type RS is a chemotherapy-resistant and devastating disease. Patients are typically elderly, immunosuppressed and present with a rapidly deteriorating performance status. Historical outcomes suggest a median overall survival of approximately 8 months. RS remains is an area of high unmet clinical need. The molecular profile and treatment needs of patients are likely to change over time with the advent of novel B cell receptor inhibitors, monoclonal antibodies and BH3 mimetics. Herein, we summarise what is known regarding the molecular drivers of RS and the existing clinical trial data, including the recently published CHOP-OR (cyclophosphamide, doxorubicin, vincristine, prednisolone and ofatumumab followed by ofatumumab maintenance in newly diagnosed RS) trial. We discuss novel agents in development with a focus on the second-generation Bruton tyrosine kinase inhibitor acalabrutinib, checkpoint inhibition and the potential role of precision medicine in future trials of RS.
A phase two study of high dose blinatumomab in Richter's syndrome. [2023]Richter's Syndrome (RS) is an aggressive transformation of CLL, usually clonally-related diffuse large B-cell lymphoma (DLBCL), characterized by frequent TP53 mutations, intrinsic chemoresistance and poor survival. TP53-independent treatments are needed. We conducted a single center, phase 2, investigator-initiated study of high dose blinatumomab (maximum 112 mcg/d after initial, weekly dose escalation), NCT03121534, given for an 8-week induction and 4-week consolidation cycle. Responses were assessed by Lugano 2014 criteria. Serial multi-parameter flow cytometry from blood was performed to identify patient-specific biomarkers for response. Nine patients were treated. Patients had received a median of 4 and 2 prior therapies for CLL and RS, respectively. Five of 9 had del(17p) and 100% had complex karyotype. Four patients had reduction in nodal disease, including one durable complete response lasting >1 y. Treatment was well tolerated, with no grade >3 cytokine release syndrome and 1 case of grade 3, reversible neurotoxicity. Immunophenotyping demonstrated the majority of patients expressed multiple immune checkpoints, especially PD1, TIM3 and TIGIT. The patient who achieved CR had the lowest levels of immune checkpoint expression. Simultaneous targeting with immune checkpoint blockade, especially PD1 inhibition, which has already demonstrated single-agent efficacy in RS, could achieve synergistic killing and enhance outcomes.
[Richter Syndrome: Diagnostic and Therapeutic Management]. [2021]Richter syndrome (RS) is defined as the occurrence of an aggressive lymphoma, most commonly diffuse large B-cell lymphoma (DLBCL) and rarely Hodgkin lymphoma (HL), in a patient with prior or concomitant chronic lymphocytic leukemia (CLL). RS is estimated to occur in 0.5-1 % per year and is associated with adverse outcome. In the vast majority of patients (80 %), RS is clonally related to the prior CLL. Those with unrelated RS appear to have better outcome. The therapeutic approach is based on those of de novo DLBCL or HL. However, even with modern immunochemotherapy regimens, response rate remains low. In eligible patients with related RS, a consolidation by autologous or allogeneic stem-cell transplantation must be proposed. Combinations including therapies targeting BCR or BCL2 and effective in CLL are currently being evaluated in RS. Novels immunotherapies could be promising approaches based on preliminary results.
Richter Transformation of Chronic Lymphocytic Leukemia-Are We Making Progress? [2023]The treatment paradigm of chronic lymphocytic leukemia (CLL) has dramatically changed with the advent of novel targeted agents over the past decade. Richter transformation (RT), or the development of an aggressive lymphoma from a background of CLL, is a well-recognized complication of CLL and carries significantly poor clinical outcomes. Here, we provide an update on current diagnostics, prognostication, and contemporary treatment of RT.
