Clinical trials

The goal of this clinical trial is to study the efficacy of the tagraxofusp + venetoclax combination in treatment-naive blastic plasmacytoid dendritic cell neoplasm adult patients. The main question is to verify the response in patients after 3 cycles of tagraxofusp+venetolax and to demonstrate if the combination of tagraxofusp + venetoclax increases the rate of complete remission, assessed after 3 months of treatment. Patients will receive a ramp-up phase of venetoclax during 3 days and at least 3 cycles of venetoclax. After, the investigators will evaluate the response, and depending on the response observed, patients may receive additional cycles of treatment for a maximum of 24 cycles, or receive an allograft or discontinue the treatment in the case of therapeutic failure.

This is a national clinical trial, multicentric (28 centers), non-randomized phase 2 study.

End of treatment is defined as after 6 cycles of R/G-CHOP + glofitamab. Permanent treatment discontinuation is defined as the discontinuation of all treatments (R/G-CHOP, glofitamab).

Prolymphocytic leukemia T is a rare disease representing approximately 2% of mature lymphoid leukemias and 20% of prolymphocytic leukemias. It mainly affects the elderly with an aggressive clinical course. It is a hemopathy exhibiting a post thymic T phenotype (Tdt-, CD1a-, CD5 +, CD2 + and CD7 +), generally CD4 + / CD8-, but also CD4 + / CD8 + or CD8 + / CD4-. The main feature of T-PLL is the rearrangement of chromosome 14 involving genes encoding the T cell receptor complex (TCR) subunits, leading to overexpression of the proto-oncogene TCL1. On the molecular level, the study of Prolymphocytic leukemia T shows a substantial mutational activation of the IL2RG-JAK1-JAK3-STAT5B axis. Patients with Prolymphocytic leukemia T have a poor prognosis, due to a poor response to conventional chemotherapy. Treatment with the anti-CD52 monoclonal antibody: alemtuzumab has considerably improved the results, but the responses to treatment are transient; therefore, patients who obtain a response to alemtuzumab treatment are candidates for stem cell allograft (TSS) if they are eligible for this procedure. This combined approach extended the median survival to four years or more. However, new approaches using well-tolerated therapies that target signaling and survival pathways are necessary for most patients who are unable to receive intensive chemotherapy, such as JAK STAT axis inhibitors, anti-AKT, or anti BCL2 . Main objective: Better manage prolymphocytic T leukemias. Secondary objectives: * Molecular characterization of prolymphocytic leukemia T. * Study of the response to treatment, disease-free survival, overall survival. * Impact of prognostic factors on response to treatment, and survival.

The evidence base in support of fixed-duration, first-line approaches in medically fit patients with CLL is clearly strengthening, whether through combining targeted agents with immunochemotherapy or through chemotherapy-free combinations. The long-term PB MRD response rates with the investagators fixed-duration (15-month) immunochemotherapy approach remain the best to date, even compared to the new targeted agent combinations of ibrutinib-venetoclax or obinutuzumab-venetoclax. The investigators' phase 2 ICLL07 trial in previously untreated fit CLL patients with a fixed-duration immunochemotherapy approach (with 4 cycles of FC-obinutuzumab and chemosparing strategy) carries a low risk for short and long term toxicities which still exist, including cardiac toxicities probably related to BTK inhibitors, moreover, two patients experienced treatment related myelodysplastic syndrome or acute myeloid leukemia beyond the end of treatment. Follow-up at 5,5 years from treatment start showed a persistent PB MRD benefit beyond end of treatment, high survival rates, and low long term toxicity with no difference in the durability of MRD response between the mutated and unmutated IGHV patients. The investigators aim to explore the safety and efficacy of a fixed duration strategy combining a new BTK inhibitor with a favorable safety profile and a limited number of ICT courses. The main goals and concerns are: i) to ensure deep response and long lasting MRD ii) to reduce the duration of BTKi exposure and the risk of clonal evolution with the appearance of deleterious mutations iii) to limit the risk of hematopoietic secondary cancers (MDS/AML) by excluding patients in whom clonal hematopoiesis of undetermined potential (CHIP) is detected before inclusion and decreasing the number of courses of chemotherapy to 3 cycles. Moreover, patients with TP53 abnormalities will be excluded with a lower cut off (1% versus 10% in the previous studies) iv) to limit the risk of BTKi toxicity by using a non-covalent BTKi

After remission post-induction and consolidation, maintenance therapy by an ivosidenib and oral azacitidine combination is susceptible to improve the prevention of AML relapse, which remains a major issue in the study population. We assume that the combination of ivosidenib with oral azacitidine will not be less well tolerated than in combination with the subcutaneous form, therapeutic regimen authorized until progression or toxicity. Ivosidenib and Onureg®, being already authorized treatments, it has been decided to use the classic administration schedules and dosages in combination. The primary objective of the study is to evaluate relapse free survival (RFS) at 24 months in patients receiving oral azacitidine with ivosidenib.

Mutations in IDH genes are found in numerous cancers and more specifically in acute myeloid leukemia (AML). These mutations target specific amino acids, at positions 140 or 172 of IDH2, and 132 of IDH1. Mutant IDH proteins acquire an abnormal enzymatic activity allowing them to convert α-ketoglutarate (αKG) into D-2 hydroxyglutarate (D-2HG), an oncometabolite which massively accumulates in IDH-mutated cells. At high levels, D-2HG behaves as a competitive inhibitor of αKG and affects the activity of Fe(II)/αKG-dependent dioxygenases. This enzymatic family is involved in a broad spectrum of pathways such as demethylation of histone (JHDM histone demethylases) or DNA (methylcytosine hydroxylases of the TET family). As a result, IDH-mutated cells show altered survival, motility, invasiveness and cell differentiation. In AML, IDH1 mutations might be present in 10-15% at diagnosis Ivosidenib (IVO) a first-in-class, oral, irreversible inhibitor of mutant IDH1 has shown clinical activity as a single agent in studies involving patients with IDH1 mutated relapsed or refractory (R/R) AML and in front line settings. In phase II clinical trials, IVO yielded 30-35% of complete response rates both in frontline and R/R settings, with long lasting responses. Based on these results, the FDA (Food and Drug Agency) gave its approval for newly-diagnosed AML IDH1mut patients who are ≥ 75 years old or who have comorbidities and in R/R. However, European Medicines Agency (EMA)'s did not approved IVO due to lack of evidences to support the application. Agios Netherlands B.V. (the company that previously own the drug before Servier Laboratories) withdrew its EMA application. Nevertheless, IVO has been available in France through a compassionate use program (CUP), since February 2020 for R/R patients and March 2022 for first line treatment. In this multicentric retrospective study, sponsor aim to evaluate the efficacy and safety of Ivo in two cohorts of IDH1mut AML patients treated within the CUP. The first cohort will concern patients treated in first line setting and the second cohort those treated in R/R disease. Results might provide new insights regarding IVO in real life settings and support signs of efficacy. This could provide new data for the haematologist community and for another appliance to grant EMA approval of IVO in the setting of R/R IDH1mut AML.

This is a French multicenter open label non-randomized Phase II trial evaluating the efficacy and tolerance of a combination of oral zanubrutinib and BGB-11417 in subjects aged 18 years and older with previously treated Waldenström macroglobulinemia (WM) who require therapy according to the consensus panel criteria from the Second International Workshop on Waldenström's macroglobulinemia. population : Patients with previously treated Waldenstrom macroglobulinemia The investigational medicinal products (IMP) are Zanubrutinib (BGB- 3111) and BGB-11417.Treatment will be administered for a total of twenty 28 day cycles: * Cycle 1 with zanubrutinib only * Cycle 2 with zanubrutinib plus BGB-11417 ramp-up * cycle 2, day 1 : 10mg * cycle 2, day 2 : 20 mg * cycle 2, day 3 : 40mg * cycle 2, day 4-7 : 80md daily * cycle 2, day 8 and beyond : 160 mg daily * Cycles 3-20 with zanubrutinib plus BGB-11417 full dose

Waldenström's macroglobulinemia (WM) is defined by the association of bone marrow lymphoplasmocytic infiltration and monoclonal immunoglobulin M (IgM). A mutation in the MYD88 gene is found in up to 90% of patients, and a mutation in the CXCR4 gene in approximately one third of patients. Treatment should be initiated in cases of cytopenia, bulky disease or when the physicochemical or immunological properties of IgM explain the occurrence of amyloidosis, cryoglobulin, neurological manifestations, or hyperviscosity syndrome (due to the presence of a large amount of IgM). However, approximately 30% of patients are diagnosed without any symptom and therefore they do not meet the criteria for initiating treatment. At the time of initiation of the first treatment, the prognosis is usually estimated with the International Prognostic Index (IPSSWM) which is based on five variables: age, platelet count, haemoglobin concentrations, β2-microglobulin and monoclonal component concentration. Serum albumin and lactate dehydrogénase (LDH) levels also retain a prognostic role and these two characteristics have been incorporated in a proposal for a revision of this index. Improving prognostic assessment at the time of the first treatment initiation and taking into account the prognostic impact of events occurring in the course of evolution, should improve the strength of treatment decision at the time of initial treatment and during the follow-up. It should also help to design clinical trial for fast and effective evaluation of new treatments. Our work should also help to adjust clinical monitoring of asymptomatic patients. Prospective and retrospective multicenter prognostic study with a descriptive objective, associated with a biological collection appropriately annotated and stored. A retrospective series including 470 patients with symptomatic WM is already available. The follow-up of these patients will be updated and an additional series of 250 symptomatic patients will be prospectively enrolled. 250 asymptomatic patients will be also enrolled.

This observational epidemiological study targets patients aged 60 and over with de novo or secondary acute myeloblastic leukemia suitable for intensive receive intensive induction therapy as defined by the group. The main aim of the study is to determine the epidemiological characteristics of AML patients, both clinically and biologically, and to correlate these to their outcome. The incidence of AML increases with age, exponentially after the age of 50, giving a median age at diagnosis of close to 70 years, with over half of patients half of patients are over 60 at diagnosis. The principle of treatment as in younger patients, is based on trying to achieve complete remission (CR). remission (CR). Observed complete remission rates range from 38 to 70%. Long-term survival of elderly subjects remains limited, at around 10 to 15%, despite the various types of consolidation tried out in recent years. years. However, intensive chemotherapy remains the preferred option for initial treatment of these hematological diseases when general condition and comorbidities allow. As shown by Swedish registry studies, it is associated with improved life expectancy. The proportion of patients who can receive intensive initial treatment is not well known in France, probably varies widely from one region to another, and certainly decreases with increasing age. Only the registry studies currently underway will enable us to assess this precisely.

Approximately 30% of adult AML subjects are refractory to induction therapy. Furthermore, of those who achieve CR, approximately 75% will relapse. FLT3-mutated AML comprise an especially poor prognosis group. Until now, there was no established standard for relapsed subjects with FLT3 mutations and less than 20% will achieve CR with subsequent treatment. In phase 3 Study ADMIRAL Trial, gilteritinib has resulted in CRc in over 25% of subjects receiving 120 mg/day before on study HSCT. With this treatment, the median overall survival is at 9.3 months, furthermore, gilteritinib was well tolerated at the proposed doses. This study has been designed for R/R patients for which gilteritinib as single agent has been showed to be superior to high- and low-intensity chemotherapy (Perl, NEJM 2019, Supp Table S4) and patients included in this study will receive this treatment. Beyond high- or low-intensity chemotherapy, other options available are best supportive car or other clinical trials. The aim of this study is to assess the efficacy and safety of the addition of oral-azacitidine to salvage treatment by gilteritinib in subjects ≥18 years of age with relapsed/refractory FLT3-mutated acute myeloid leukemia

Following the results of the phase 1b and the phase 3 studies, Venetoclax/Azacitidine (VEN/AZA) was available in France for newly diagnosed AML patients ineligible-IC patients through the early access program the so-called ATU program. Venetoclax (VEN) has been available in France through the ATU since Feb 2021 and through the current post-ATU schema from the point of marketing authorization approval and up to the pending publication of reimbursement and price. Between February 15, 2021, and June 30, 2021, 285 requests for ATU were made to the pharmaceutical company (Abbvie) and led to the initiation of treatment of more than 230 patients. At the end of ATU period, all these 230 ATU patients continued to be treated by VEN/AZA as part of the current post-ATU period. Healthcare professionals and health care decision makers need real world data to better understand the benefit/risk profile of treatment. Early access to treatment in France is close to real-life setting condition.
