Clinical trials

The current standard of care treatment for adult patients with acute myeloid leukemia (AML) consists of chemotherapy and, if indicated, donor stem cell transplantation. Bleximenib blocks the interaction between a protein called menin and another protein called KMT2A in the leukemia cells. When this interaction is disrupted in AML with mutations in the NPM1 or KMT2A gene, bleximenib can cause leukemia cells to die. The main objective is to assess if treatment with bleximenib, when added to chemotherapy treatment will improve treatment outcome in adult participants with newly diagnosed AML who present with mutations in the NPM1 or KMT2A genes. This is a randomized, double-blind, placebo-controlled, phase 3 clinical trial. All of the participants will receive standard chemotherapy treatment, combined with either bleximenib or a placebo. A placebo is a substance that looks like the study medicine but has no active ingredients (e.g., a sugar pill). In a double blind trial neither the participant nor the doctor know if placebo or active study drug is given. After the end of the protocol treatment there will be an observational follow-up of 4 years from the time of inclusion of the last patient. The results of the different treatment groups will be compared. 875 previously untreated patients with AML with a specific change in the DNA of the leukemia cells (a KMT2A rearrangement or a NPM1 mutation) will be included. Participants must be 18 years or older and considered eligible for intensive chemotherapy.

Patients treated for DLBCL are at high risk of developing AICD. This adverse event is characterized by irreversible damage to the heart muscle with a loss of cardiomyocytes and subsequent decline in cardiac pumping capacity. Thereby patients treated for this malignancy are at double the risk of developing symptomatic heart failure / cardiomyopathy when compared to the general population. This corresponds to a cumulative incidence of 5-10% within 5-years after receiving R-CHOP. In the elderly, an incidence of 26% has been reported after 8-years of follow-up. Among patients who die in complete remission, heart failure has been described to be one of the most important causes of death. ANTICIPATE aims to evaluate if dexrazoxane can prevent AICD in DLBCL patients and identify those at highest risk of AICD. Of all patients treated with anthracyclines in a first-line setting, DLBCL patients were chosen for this trial for two primary reasons. Firstly, these patients have a favourable oncological prognosis with a 5-year relative survival in the Netherlands of 64-78% in those aged 18-74 years increasing the importance of preventing long-term toxicity. Secondly, the cumulative anthracycline dose used for the treatment of DLBCL is higher than the dose used in breast cancer. The cumulative anthracycline dose is the most important risk factor for AICD known.

Fixed-duration regimens containing combinations of venetoclax with CD20 targeting agents are expected to soon become standard practice in first-line patients with chronic lymfocytic leukemia (CLL). The advantage of a fixed duration venetoclax combination as part of first-line treatment is the potential to retreat with venetoclax in patients who develop relapsed disease after a treatment free period. However, efficacy of venetoclax retreatment following a fixed duration venetoclax combination is still hypothetical as clinical data are lacking. Thus, there is an urgent need for data proving efficacy of venetoclax combinations following venetoclax treatment cessation. Testing of a novel venetoclax-containing regimen for relapsed CLL without the repeat of anti-CD20 monoclonal antibody (mAb) is a rational approach.

The standard treatment for patients with acute myeloid leukemia (AML) with an abnormality in the IDH1 gene, who are not eligible for intensive chemotherapy, is a combination of ivosidenib and azacitidine. In this study it is investigated whether adding venetoclax to the standard treatment can improve the outcome of the treatment of this specific form of AML. The safety is investigated and how well it works. In order to properly assess the value of venetoclax, the effect of venetoclax is compared with the effect of a placebo. A placebo is a product without an active ingredient, a 'fake medicinal product'.

Treatment of patients with newly diagnosed AML who are not eligible for intensive chemotherapy has remained an area of high unmet medical need. The combination therapy with two medicines, azacitidine and venetoclax, is the usual plan of action. This has brought significant progress in the treatment, but it nevertheless is not curative and the disease does relapse over time. Revumenib blocks a specific molecule called menin in the cell nucleus. Some types of AML are reliant on menin working properly. These are leukemia cells with a change in the DNA, i.e. a mutation in the NPM1 or KMT2A gene. Revumenib can prevent the production of these types of leukemia cells by disrupting the production of this menin. The current study investigates whether adding revumenib to the combination therapy improves the prognosis for AML patients with a mutation in the NPM1 or KMT2A gene. This is a randomized, double-blind, placebo-controlled clinical study where subjects will be treated until disease progression, or development of side effects or death. From the moment of inclusion of the last patient, there will be a 4-year observational follow-up study in order to register survival duration and follow-up visits. Approximately 415 previously untreated patients with a mutation in the NPM1 or KMT2A gene and with newly diagnosed AML, who are not eligible for intensive chemotherapy. Patients must be ≥18 years of age.

The goal of this clinical trial is to learn if therapy can be improved in patients with myelofibrosis (MF) who have primary resistance or who have progressed after treatment with a Janus kinase (JAK) inhibitor or are intolerant for this category of drugs. The main questions it aims to answer are: * To evaluate the feasibility and safety of once daily dose of tasquinimod for 24 weeks (6 cycles) * To determine the optimal dose Patients will be treated once daily with tasquinimod for a maximum period of 24 weeks (6 cycles). During the study most (diagnostic) procedures are part of the standard of care. Different from standard of care: * Participation may lead to extra visits to the outpatient clinic * Additional blood will be drawn when blood is already taken per standard of care * Bone marrow sampling at entry and at the end of the trial * MRI scans (or CT-scans) have to be performed * Quality-of-life questionnaires have to be filled out

In the Netherlands, the standard treatment for multiple myeloma is a combination of different medicines named daratumumab-lenalidomide-dexamethasone, abbreviated as Dara-Rd. In many patients this treatment results in suppressing the disease for a long time. The treatment is continued until it is not effective anymore and the disease progresses. But until now it is unknown whether continuous therapy also leads to prolonging life. In addition, there are concerns about side effects, leading to a reduced quality of life, the development of severe toxicity that remains, which hampers subsequent therapy, and high costs due to prolonged treatment. There are indications that temporarily stopping treatment is safe, leading to fewer side effects and allows recovering from toxicity or damage due to treatment. This may improve the quality of life.

In this study, efficacy and safety of 2 regimens that combine the CD3-CD20 T cell engager epcoritamab with venetoclax will be tested in relapsed/refractory CLL and SLL patients. The trial starts with phase I part to establish the recommended dose level (RDL) of epcoritamab in the combination with venetoclax for the phase II trial.

The treatment of older unfit patients with acute myeloid leukemia (AML) is challenging. The hypomethylating agents (HMA) azacitidine and decitabine have relatively mild side effects and have proven to be feasible for the treatment of older patients and patients with co-morbidities. Currently, venetoclax added to an HMA agent is the new standard of treatment. Since this new standard comes with a substantial societal financial burden, there is a rational to optimize the venetoclax dosing schedule. The CYP3A4 inhibitor cobicistat (COBI) can be used to increase venetoclax exposure, thereby allowing to reduce the dose of venetoclax and thus costs substantially.

Patients with CD30 positive DLBCL, primary refractory or in first relapse after R-CHOP or R-CHOP-like therapy will receive brentuximab vedotin in combination with R-DHAP, followed in responsive patients by high dose chemotherapy and ASCT.
