French Observational Study of Patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma in Real-World Settings

Chronic lymphocytic leukemia (CLL) is the most frequent form of leukemia in the Western World. The disease is characterized by the accumulation and proliferation of mature, monoclonal, CD5+ B-cells with specific immunophenotype in the peripheral blood (above 5x109/L), bone marrow and secondary lymphoid organs. Small lymphocytic leukemia (SLL) is characterized by similar tumor cells but without increased lymphocyte count. In Europe, CLL has been identified as the second most frequent hematological malignancies after multiple myeloma (Eurocare 5 study) and its standardized incidence in the world has been estimated to be 4/100000 person-years for men and 2.1/100000 person-years for women. In France, 4674 new cases have been observed in 2018 (FRANCIM). A proportion of patients can initially be monitored only while others with symptomatic disease at diagnosis or during follow-up require therapies. The management of these patients have considerably changed over the last decade. Indeed, beyond chemo-immunotherapy, multiple targeted therapies have been approved on the basis of phase 2 and randomized phase 3 clinical trials and have subsequently been used in daily practice. The management of patients with SLL is similar to that of those with CLL. In addition to therapeutic advances, the advent of new sequencing technologies has also identified CLL genetic features that are now being incorporated in patient routine evaluation. Conventional chemo-immunotherapy (CIT) has been the long-standing option for CLL patient without TP53 disruption and different regimens have emerged depending on patient comorbidities (fludarabine-cyclophosphamide-rituximab, FCR; bendamustin-rituximab, BR; GA101-chloraminophene, G-CLB). These regimens fail to be effective in patients with TP53 disruption and alternative strategies are proposed for them. The CLL therapeutic panel is now enriched by oral kinase inhibitors targeting the B-cell receptor signaling. The Bruton's tyrosine kinase inhibitors (BTKi) have been shown to provide prolonged response, even in cases where CIT usually failed, such as patients harboring TP53 disruption. In relapsed/refractory patients, median PFS with the BTKi ibrutinib is 44 months. In the frontline setting, ibrutinib has recently been shown to result in superior PFS and less infectious complications than standard CIT regimens. The advent of the BCL2 (B-cell lymphoma 2) inhibitor venetoclax has recently added another option for the treatment of CLL patients. BCL2 is an antiapoptotic molecule governing mitochondrial apoptosis and is strongly expressed in CLL cells. Inhibiting BCL2 with venetoclax as monotherapy led to 79% response rate in the relapse/refractory setting. Combining venetoclax to rituximab demonstrated better PFS than bendamustine-rituximab in relapsed/refractory patients. However, these treatment approaches also come with new challenges that are difficult to-address in phase 3 clinical trials and that deserve larger scale studies and longer follow-up. The emergence of drug resistance, the changes of safety profiles to deal with in routine practice and the observance of these orally administered drugs are emerging as new concerns. How these compounds change the incidence of typical CLL complication such as Richter transformation, immune cytopenias and infections remains to be determined. A growing body of concerns is also raising regarding the unlimited administration of some of this the compounds (costs, resistance, tolerance). Finally, the optimal order of use of these drugs is unknown. The advent of the BCL2 (B-cell lymphoma 2) inhibitor venetoclax has recently added another option for the treatment of CLL patients 11,12. BCL2 is an antiapoptotic molecule governing mitochondrial apoptosis and is strongly expressed in CLL cells. Inhibiting BCL2 with venetoclax as monotherapy led to 79% response rate in the relapse/refractory setting. Combining venetoclax to rituximab demonstrated better PFS than bendamustine-rituximab in relapsed/refractory patients12.

Primary objective : Setting a prospective cohort of real-world CLL/SLL patients with symptomatic disease in order to evaluate medical practices and their change and representativity over time. Secondary objectives : Overall survival and long-term toxicity, Response and PFS at each line of therapy, Impact of therapeutic trajectories on patient outcome, Representativity of the studied population

A Study of Secukinumab to Evaluate Maintenance of Response in Participants With Non-radiographic Axial Spondyloarthritis Who Achieved Remission

This study will establish whether prolonged chronic dosing with secukinumab is needed in participants with nr-axSpA who have achieved remission. Remission is defined as Ankylosing Spondylitis Disease Activity Score - C-reactive protein (ASDAS-CRP) Inactive Disease (ID) response Inactive Disease (ID) response (ASDAS-CRP < 1.3). The maintenance of remission on continued secukinumab treatment will be evaluated compared to placebo using a randomized withdrawal design. The primary outcome measure for this study is the proportion of participants remaining flare-free at Week 120. Study treatment will be as follows: - Open-label Secukinumab PFS (prefilled syringe) will be labeled as AIN457 150mg/1mL - Double-blind Secukinumab and Placebo PFS will be labeled as AIN457 150mg/1mL/Placebo. Study duration will be up to 128 weeks from Baseline. The treatment duration will be up to 120 weeks with last treatment administration at Week 116. In the Treatment Period 1 participant will attend a site visit approximately 1 month after Baseline and approximately every 12 weeks thereafter. In the Treatment Period 2 participant will attend site visits approximately every 4 weeks.

Efficacy of a Sequential Treatment Strategy in Rheumatoid Arthritis

In rheumatoid arthritis (RA), the consensual 1st line conventional synthetic disease modifying antirheumatic drugs (csDMARD) of RA is methotrexate (MTX) (1). In case of contra-indication or intolerance to MTX, leflunomide is an alternative. If the treatment target is not achieved with csDMARD strategy, addition of a biological (b) DMARD (TNF inhibitors, anti-IL6, abatacept, or rituximab) or a targeted synthetic (ts) DMARD (JAK inhibitors) is considered. Current practice is to start a bDMARD and especially TNF inhibitors (etanercept or monoclonal anti-TNF antibodies) with the benefit of hindsight. However, abatacept and TNF inhibitors have demonstrated similar efficacy in patients with insufficient response to csDMARD (AMPLE trial). Although abatacept has shown a very good tolerance profile that might be superior to other bDMARDs rheumatologists might be reluctant to use it as a first line bDMARD as there is a belief of a slower efficacy compared to other bDMARDs or JAK inhibitors. Indeed, in real world study, compared to TNF inhibitors it seems that discontinuation of abatacept is more related to lack of effectiveness than safety issues. This is the first study to propose a therapeutic sequential strategy with an induction therapy using a TNF inhibitor for 12 weeks to control inflammation followed by a cell-targeted biological DMARD targeting T cells (abatacept) in order to decrease auto-antibodies (rheumatoid factor and/or ACPA). Presence of auto-antibodies (ACPA/RF) are predictive of better response to cell- targeted DMARDs. In early AMPLE trial, RA patients ACPA+ with insufficient response to MTX were treated with abatacept or adalimumab. DAS28-CRP remission rates were 55% in abatacept group and 30% in adalimumab group. Patients carrying the shared epitope (HLA-DR (Human Leucocyte Antigen-DR) alleles associated with RA), were also more likely to reach remission (DAS28-CRP<2.6) with abatacept (50%) than adalimumab (23%) at 24 weeks. The clinical trial offered by investigateors here could change the paradigm in the strategy used in RA supporting the importance to first control inflammation environment in order to allow the cell-targeted bDMARDs to control immunological process which has been recently associated with a higher percentage of clinical remission. To compare the percentage of remission (DAS28-CRP<2.6) obtained during the 36 weeks following randomization, with a sequential therapeutic strategy using abatacept versus a routine strategy continuing TNF inhibitors (TNFi), in ACPA positive RA patients responding to a first TNFi, initiated 12 weeks before randomization. The primary endpoint will be analyzed with a generalized estimating equations (GEE) model for repeated data. It is a multicentric, open label, randomized controlled trial comparing two different strategies of treatment with an independent efficacy assessor. For this clinical trial, to limit response bias, bDMARDs with a similar mode of administration (subcutaneous) are proposed. In the experimental arm, a therapeutic sequential strategy will be proposed and in the control arm TNF inhibitors will be proposed for 48 weeks. All included patients will receive TNF inhibitors subcutaneous for 12 weeks. At 12 weeks (W12), patients who have at least a moderate EULAR response (delta DAS28-CRP between W0 and W12>0.6 and DAS28-CRP≤5.1 at W12) will be randomized with a 1:1 ratio in the sequential strategy arm or the control arm. In the sequential strategy arm, the 88 randomized RA patients will be switched to abatacept subcutaneous for 36 weeks. Patients who will withdraw abatacept during the follow-up will be considered as a failure. In the control group, the 88 randomized RA patients will be treated with TNF inhibitor subcutaneous for another 36 weeks. In case of insufficient response to a first TNF inhibitor at 24 or 36 weeks, a second TNF inhibitor will be proposed. Anti-TNF drugs withdrawal will be considered as a failure. Steroids 0.1mg/kg/ day will be allowed but at stable dose 2 weeks before and with guided step-down strategy targeting withdrawal before 24 weeks following randomization. Clinical evaluation of disease activity using different scores (DAS28-ESR, CDAI, SDAI, Boolean criteria) and tolerance will be performed at all visits.

Clinical Study of Fianlimab in Combination With Cemiplimab Versus Pembrolizumab in Adolescent and Adult Patients With Previously Untreated Unresectable Locally Advanced or Metastatic Melanoma

A Study of Amivantamab Monotherapy and in Addition to Standard-of-Care Chemotherapy in Participants With Advanced or Metastatic Colorectal Cancer

Colorectal cancer (CRC) is a major global health concern and the third most common cancer worldwide. Amivantamab (also known as RYBREVANT or JNJ-61186372) is a fully human immunoglobulin (Ig) G1-based bispecific antibody (Ab) directed against the epidermal growth factor (EGF) and mesenchymal epithelial transition (MET) receptors, with evidence of preclinical activity against non-small cell lung cancer (NSCLC) tumors with activating EGF receptor (EGFR) mutations, the T790M and C797S second-site resistance EGFR mutations, overexpressed wild-type EGFR, as well as with activation of the MET pathway. Amivantamab has demonstrated activity in both EGFR- and MET-driven NSCLC, with preclinical evidence demonstrating its ability to recruit immune effector cells. While two anti-EGFR antibodies are incorporated as part of the SoC for CRC patients, MET is highly expressed or amplified in subsets of CRC and additionally plays a role in mediating resistance to anti-EGFR treatments. The study consists of up to 28 days screening period, treatment period will begin on Cycle 1 Day 1 (C1D1) (for Cohorts A, B, and C) or C1D -2 (for Ph1b-D, Ph1b-E, Cohorts D and E) with the administration of the study treatment and continue as 28-day cycles until the end of treatment visit, up to 30 days after discontinuation of study treatment. The safety of amivantamab as a monotherapy or in addition to SoC chemotherapy will be assessed by physical examinations, Eastern Cooperative Oncology Group (ECOG) criteria for performance status (PS), laboratory tests, vital signs, monitoring of adverse events, and concomitant medication usage. The total duration of this study will be up to 4 years 3 months.
