Filter by:This is a Phase 1 dose-escalation study of PRT2527, a potent and highly selective cyclin-dependent kinase (CDK) 9 inhibitor, in participants with select relapsed or refractory (R/R) hematologic malignancies. The purpose of this study is to evaluate the safety, tolerability, recommended phase 2 dose (PR2D), and preliminary efficacy of PRT2527 as a monotherapy and in combination with zanubrutinib.
Richter's syndrome (RS) is a life-threatening complication of chronic lymphocytic leukemia (CLL). 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). The development of RS is accompanied by the onset of B symptoms, rapid growth of lymphadenopathy, extra-nodal disease, significant elevations of lactate dehydrogenase (LDH), and associated multi-organ dysfunction from invasive or obstructive processes RS occurs in 2-10% of CLL patients with an incidence rate of 0.5% per year. The molecular pathogenesis of RS involves inactivation of the tumor protein p53 (TP53) tumor suppressor gene in 50-60% of cases and activating aberrations of NOTCH1 and myelocytomatosis oncogene (MYC) in about 30% of cases. . These distinct molecular footprints of RS are chemoresistance leading to an aggressive clinical course with low response rates and poor outcomes.Taking into consideration that in addition to the underlying aggressive disease, most RS patients are often at an advanced age and suffer from numerous other comorbidities. Additionally, intensive chemotherapy regimens are highly toxic to this population group and lead to excessive treatment-related morbidity. Enrolling DLBCL-RS patients in clinical trials is therefore justifiable, particularly those with RS that is clonally related to the predisposed underlining CLL disease. Due to the poor activity of immunochemotherapy, the possibility of using novel agents in the treatment of RS is of great interest. The toxicity and the efficacy of the combination of cluster of anti differentiation antigen 20 (anti-CD20) antibody (e.g. Obinutuzumab or Rituximab) with Ibrutinib and/or Venetoclax have been already reported in both relapsed and naïve patients with CLL. The use of these three agents in combination is highly active in CLL and has manageable side effects. In addition, recent reports showed that treatment with Ibrutinib or Venetoclax as a single drug are active in RS. Herein the investigators propose a phase 2, open-label, non-randomized, single arm, multi-center study aiming to assess the safety and efficacy with the combination of Ibrutinib, Venetoclax and Obinutuzumab in patients with RS .
The study is a global, multi-center safety and efficacy trial of epcoritamab, an antibody also known as EPKINLY™ and GEN3013 (DuoBody®-CD3xCD20). Epcoritamab will either be studied as: - Monotherapy, or - Combination therapy: - epcoritamab + venetoclax - epcoritamab + lenalidomide - epcoritamab + R-CHOP (i.e., rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine and prednisone). The study includes patients with relapsed/refractory chronic lymphocytic leukemia (R/R CLL)/small lymphocytic lymphoma (SLL) and patients with Richter's Syndrome (RS). Study participants with R/R CLL/SLL are treated either with epcoritamab as monotherapy or epcoritamab + venetoclax. Study participants with RS are treated either with epcoritamab as monotherapy or epcoritamab + lenalidomide or epcoritamab + R-CHOP. The trial consists of two parts, a dose-escalation phase (phase Ib) and an expansion phase (phase II). Patients with RS are only included in the expansion phase.
The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and preliminary antitumor activity of AZD4573 in subjects with relapsed or refractory haematological malignancies.
The purpose of the study is to investigate whether combination of obinutuzumab, lenalidomide, and high dose methylprednisolone in the treatment of Richter's Syndrome. The study will evaluate whether this regimen can reduce the amount of cancerous cells in your body. All of these agents are approved by the FDA Obinutuzumab is a protein molecule manufactured from a single cell population, has been approved by the Food and Drug Administration (FDA) for the treatment of CLL of SLL. Lenalidomide is for the treatment of patients with other blood cancers. Methylprednisolone is a type of steroid, and it is used in a wide variety of medical conditions. These agents and the combination of these agents are not approved for the treatment of Richter's Syndrome and are considered experimental.
This study is evaluating the safety, pharmacodynamics (PD), and efficacy of acalabrutinib and pembrolizumab in hematologic malignancies.
This study is evaluating the safety and efficacy of a new BTK inhibitor, acalabrutinib, for the treatment of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL).
The purpose of this study is to evaluate Ofatumumab in combination with CHOP (cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin (vincristine), and prednisone/prednisolone, the standard chemotherapy treatment) in induction and maintenance treatment of Richter's Syndrome. This study aims to evaluate the overall response rate to CHOP-O (CHOP in combination with Ofatumumab) according to the Revised Response Criteria for Malignant Lymphoma. The hypothesis would be that treatment with CHOP-O for Richter's Syndrome (RS), shows a difference in overall survival (more people living longer), when compared with the standard treatment of CHOP-R (CHOP chemotherapy plus Rituximab).
