Clinical trials Below are current clinical trials.78 studies in Hematology (open studies only). Filter this list of studies by location, status and more. Rituximab, Romidepsin, and Lenalidomide in Treating Patients With Recurrent or Refractory B-cell Non-Hodgkin Lymphoma Rochester, Minn., Scottsdale/Phoenix, Ariz. This phase I/II trial studies the side effects and best dose of romidepsin and lenalidomide when combined with rituximab and to see how well this combination works in treating patients with B-cell non-Hodgkin lymphoma that has returned (recurrent) or did not respond to treatment (refractory). Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Romidepsin and lenalidomide may stop the growth of cancer cells by blocking enzymes needed for cell growth. Giving rituximab together with romidepsin and lenalidomide may be a better treatment for B-cell non-Hodgkin lymphoma. A Study to Evaluate Minimal Residual Disease in Chronic Lymphocytic Leukemia Rochester, Minn. The purpose of this study is to compare whether minimal residual disease (MRD) flow cytometric assay is not affected by different anticoagulants. Hematology Electronic Consultations (e-Consults) the Mayo Clinic Experience Jacksonville, Fla. The purpose of this study is to evaluate hematology e-consults to determine their specific use, time to completion, advantages and disadvantages, perceptions from primary care physicians and specialists and economic impact. A Study of JNJ‐68284528 Out‐of‐Specification (OOS) for Commercial Release in Patients with Multiple Myeloma Rochester, Minn. The purpose of this study is to evaluate the effectiveness of cilta-cel OOS based on overall response of partial response (PR) or better (overall response rate, ORR) to treat multiple myeloma. Expanded Access Study for the Treatment of Patients With Commercially Out-of-Specification Axicabtagene Ciloleucel Jacksonville, Fla., Rochester, Minn. The goal of this study is to provide access to axicabtagene ciloleucel for patients diagnosed with a disease approved for treatment with axicabtagene ciloleucel, that is otherwise out of specification for commercial release. A Study to Evaluate Lenalidomide and Dexamethasone, with or without Daratumumab, in Treating High-Risk Smoldering Myeloma Patients Rochester, Minn., Albert Lea, Minn., Eau Claire, Wis. The purpose of this study is to show how well lenalidomide and dexamethasone work with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma. MC230818 Understanding the mechanisms of clonal and non-clonal cytopenia following CAR-T therapy (MC230818) Mankato, Minn., Rochester, Minn., La Crosse, Wis., Jacksonville, Fla., Scottsdale/Phoenix, Ariz., Eau Claire, Wis., Albert Lea, Minn. Determine the preexisting and therapy-emergent germline and somatic variants associated with an increased risk of clonal and non-clonal cytopenia following CAR-T cell therapy. A Study of CA-4948 in Patients With Relapsed or Refractory Primary Central Nervous System Lymphoma Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz. This is a multi-center, open-label trial of orally administered CA-4948 monotherapy in adult patients with Relapsed or Refractory NHL. The trial will be conducted in 2 parts: an initial Dose Escalation Phase (Part A) of CA-4948 in patients with Relapsed or Refractory Non-Hodgkin Lymphoma, (RR NHL) and a Dose Expansion Phase (Part B) of CA-4948 in patients with RR NHL with and without myeloid differentiation primary response 88 (MYD88) mutations. During Part B, patients will be enrolled regardless of MYD88 mutation status. A Study Evaluating The Safety, Efficacy, And Pharmacokinetics Of Mosunetuzumab And A Combined Regimen Of Mosunetuzumab And Venetoclax In Participants With Relapsed Or Refractory Chronic Lymphocytic Leukemia Rochester, Minn. This study will assess the safety, tolerability, pharmaokinetics, and preliminary efficacy of mosunetuzumab (Lunsumio) monotherapy in participants with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL). This study will also allow participants who are currently progressing on a Bruton tyrosine kinase inhibitor (BTKi) and requiring salvage therapy as assessed by the treating physician to continue their BTKi throughout the screening period and for the first two cycles of mosunetuzumab. An additional arm (open to non-US participants only) has been added to assess the safety, tolerability, pharmacokinetics, and preliminary efficacy of mosunetuzumab in combination with venetoclax, a B-cell lymphoma 2 (BCL2) inhibitor. A Study to Evaluate Immune and Hematopoietic Cell Assessment in Clonal B Cell Conditions Rochester, Minn. The purpose of this study is to evaluate the immune and hematopoietic compartments in patients with monoclonal B cell lymphocytosis (MBL) and chronic lymphocytic leukemia (CLL) in comparison to age-matched healthy control (HC) donors.

The patient comes first. So the mission and research here is to advance how we can best help the patient, how to make sure the patient comes first in care. So in many ways, it's a cycle. It can start with as simple as an idea worked on in a laboratory, brought to the patient bedside, and if everything goes right — and let's say it's helpful or beneficial — then brought on as a standard approach. And I think that is one of the unique characteristics of Mayo's approach to research — that patient-centeredness — that really helps to put it in its own spotlight.
