1 Phase 1/2 Open-Label, Multiple-dose, Dose-escalation Study to Evaluate the Safety and Tolerability of IMO-8400 in Patients With Relapsed or Refractory Waldenstrom's Macroglobulinemia

Recent reports have identified a specific oncogenic mutation L265P of the MYD88 gene in approximately 90% of the patients with Waldenström's macroglobulinemia. MYD88 is a key linker protein in the signaling pathway of Toll Like Receptors (TLRs) 7, 8, and 9, and IMO-8400 is an oligonucleotide specifically designed to inhibit TLRs 7,8, and 9. The scientific hypothesis for use of IMO-8400 to treat patients with Waldenström's macroglobulinemia depends on the inhibition of mutant MYD88 signaling in the TLR pathway, thereby interrupting the proliferation of cell populations responsible for the propagation of the disease.

2 Phase I/II Open-label, Multiple-dose, Dose-escalation Study to Evaluate the Safety and Tolerability of IMO-8400 in Patients With Relapsed or Refractory Diffuse Large B-Cell Lymphoma and Presence of the MyD88 L265P Mutation

Recent reports have identified a specific oncogenic mutation L265P of the MYD88 gene in approximately 30% of the patients with the activated B-cell (ABC) type of Diffuse Large B Cell Lymphoma (DLBCL). MYD88 is an initial adapter linker protein in the signaling pathway of the Toll Like Receptors (TLRs), including the endosomal TLRs 7, 8, and 9, for which the ligands are nucleic acids. IMO-8400 is an oligonucleotide specifically designed to inhibit ligand activation of TLRs 7,8, and 9. Recent studies indicate that in the presence of L265P mutation ligand activation of those TLRs results in markedly increased signaling with subsequent increased cell activation, cell survival, and cell proliferation. The scientific rationale for assessing the use of IMO-8400 to treat patients with DLBCL and the L265P mutation is based on laboratory observations that IMO-8400 inhibits ligand-based activation of cells with the mutation and decreases the survival and proliferation of the cell populations responsible for the propagation of the disease.

4 Molecular Disease Profile of Haematological Malignancies. A Prospective Registry Study by the Rete Ematologica Lombarda (REL) Clinical Network

In this prospective multicentric study, the University of Pavia together with the Fondazione IRCCS Policlinico San Matteo, Pavia and the IRCCS Fondazione Maugeri, Pavia, Italy will provide a systematic analysis of gene mutations in hematological malignancies by using NGS techniques. Patients with a conclusive diagnosis of haematological malignancies according to WHO criteria referred to the Rete Ematologica Lombarda clinical network (REL, www.rel-lombardia.net) will be enrolled. The investigators will analyse genomic DNA extracted from hematopoietic cells at different time points of patient disease. The study contemplates the use of molecular platforms (Next Generation Sequencing, NGS) aimed at the identification of recurrent mutations in myeloid and lymphoid neoplasms, respectively. Screening of gene mutations by NGS will be prospectively implemented in the context of REL clinical network. Patient samples will be analyzed at diagnosis and sequentially during the course of the disease at specific timepoints. The researchers will analyze the correlations between somatic mutations, specific clinical phenotypes (according to the WHO classification) and disease evolution. This will allow to: 1) identify new recurrent genetic mutations involved in the molecular pathogenesis of hematological malignancies; 2) define the role of mutated genes, distinguishing between genes which induce a clonal proliferation of hematopoietic stem cells, and genes which determine the clinical phenotype of the disease; 3) identify mutations which are responsible for disease evolution; 4) define the diagnostic/prognostic role of the identified mutations, and update the current disease classifications and prognostic scores by including molecular parameters. A systematic biobanking of biological material will be provided.

6 Expression of Ku70/XRCC6 and Others NHEJ Components in Waldenström's Macroglobulinemia in Comparison With Others B-cell Lymphoproliferative Disorders and Normal B Cells.

Waldenström's macroglobulinemia is a rare disease whose pathophysiology remains at present poorly understood, although a recurrent mutation (L265P MYD88) has recently been described. Unlike other lymphoproliferative disorders, there is a defect in isotype switching, mechanism involving AID and NHEJ complex. Using a two-dimensional electrophoresis technology, our group showed that MW had a specific proteomic profile, and one of the differentially expressed proteins is Ku70 (encoded by XRCC6 belonging to NHEJ complex) . The investigators purpose to explore the mechanisms of underexpression of Ku70/XRCC6 (genetic or epigenetic modification) in comparison with other lymphoid malignancies and normal B cells.

7 Observational Study of the Prevalence of Some Genetic Mutations in Patients With Neuropathy Associated With Anti-Myelin-associated Glycoprotein (MAG) Antibodies.

Anti-MAG (Myelin Associated Glycoprotein) neuropathy is related to clonal B lymphocyte proliferation producing an monoclonal immunoglobulin (IgM) with anti-MAG activity. IgM may be a reflection of malignant lymphoproliferative syndrome (Waldenström disease) or, more often, monoclonal gammopathy of unknown significance. The anti-MAG antibody has a direct toxicity on the myelin sheath of the peripheral nervous system responsible for a length-dependent demyelinating polyneuropathy. Clinically, this results in a sensitive, ataxic predominant polyneuropathy in the lower limbs, sometimes associated with a tremor of attitude and action tremor of the upper limbs. Clonal B cells at the origin of IgM production may have acquired mutations affecting MYD88 (MYD88 L265P mutation) and CXCR4 (Whim-like CXCR4 mutation). The prevalence of the MYD88 L265P mutation is estimated to be 50% in monoclonal gammopathies of undetermined significance and more than 80% in Waldenström disease. CXCR4 Whim-like mutations are found in 40% of patients with Waldenström's disease. No studies have reported the prevalence of these mutations in patients with anti-MAG neuropathies.

9 Detection by Digital PCR and Next Generation Sequencing of Recurrent Mutations in Waldenström's Disease and Study of Their Distribution in the Different Biological Compartments

Waldenström's disease (WM) is a rare, low-grade lymphoid hematopathy, accounting for 1 to 2% of malignant hematopathies and mainly affecting the elderly. This disease is characterized by lymphoplasmocyte cells infiltration into the bone marrow and by the production of a monoclonal IgM protein in the serum. This disease is accompanied by clinical manifestations of hepato-splenomegaly, signs of hyperviscosity, peripheral neuropathies and biological signs with the presence of cytopenias and cryoglobulinemia. Some forms present node or splenic involvement. While the asymptomatic form maintains overall survival close to that of the healthy subject, the symptomatic form is subject to frequent relapses and remains incurable. Current recommendations for the diagnosis and monitoring of this disease are based on protein electrophoresis from a blood sample to quantify monoclonal IgM production and a myelogram or bone marrow biopsy showing medullary infiltration by lymphoplasmocytic cells. However, protein electrophoresis is an imprecise examination since it does not quantify tumour B lymphocytes and has limitations, particularly in the case of poorly secreting forms. More than 90% of Waldenström cases have the L265P mutation of the MYD88 gene. Although this mutation is not found only in these diseases, it can help in the diagnosis. Other mutations are also present in this pathology. These mutations can define prognostic factors or possibly make it possible to identify therapeutic targets. The development of new technologies makes it possible, on the one hand, to follow the L265P mutation of MYD88 over time as a marker of response to treatment and, on the other hand, to define these prognostic markers or therapeutic targets. This study will first determine the best method for monitoring the mutation of MYD88. In a second step, the investigators will evaluate the best type of sampling and in particular whether this mutation is present in the blood in order to limit the invasive procedures such as bone marrow sampling can be limited. Finally, the investigators will evaluate the prognostic

Comparison of level of MYD88L265P mutationin different biological compartment c.. Allelic frequency of L265P mutation of MYD 88 gene. --- L265P ---

Inclusion Criteria: - Over 18 years of age - recently diagnosed for Waldenström's disease - not yet treated for Waldenström's disease Exclusion Criteria: - Pregnancy or breast feeding - HBV or HBC positive - HIV positive Inclusion Criteria: - Over 18 years of age - recently diagnosed for Waldenström's disease - not yet treated for Waldenström's disease Exclusion Criteria: - Pregnancy or breast feeding - HBV or HBC positive - HIV positive Waldenstrom's Disease Osteochondritis The L265P mutation of MYD88 appears as an early oncogenic event in the occurrence of Waldenström disease and may already be present at the Monoclonal Gammapathy of Undetermined Signification (MGUS) to IgM stage suggesting a continuum between the two stages of the disease. --- L265P ---

Monitoring the L265P mutation of MYD88 as a marker of minimal residual disease therefore appears to be a biomarker of major interest in these diseases. --- L265P ---

Several published studies show the interest of monitoring the L265P mutation of MYD88 in MW in particular by quantification of the mutation by allele-specific PCR. --- L265P ---

The originality of this study is based on the comparison of the quantification of the MYD88 L265P mutation in all affected biological compartments (blood, plasma, bone marrow or CD19+ cells) but especially in the monitoring of the mutation at two points of minimal residual disease (mid-treatment and end of treatment). --- L265P ---
