Despite the improvement in prognosis since the advent of rituximab, follicular lymphoma is still incurable and remains the cause of death of most afflicted patients. With the expanding knowledge of the pathogenesis of B-cell malignancies, in the last few years a plethora of new therapies acting through a variety of mechanisms have shown promising results. This review attempts to analyze the evidence available on these new drugs, which include new monoclonal antibodies and immunoconjugates, the anti-angiogenic and immunomodulatory agent lenalidomide, the proteasome inhibitor bortezomib, inhibitors of B-cell receptor pathway enzymes, such as ibrutinib, idelalisib, duvelisib and entospletinib, BCL2 inhibitors and checkpoint inhibitors...

Phosphoinositide-3-kinase (PI3K) is an enzyme group, known to regulate key survival pathways in acute myeloid leukaemia (AML). It generates phosphatidylinositol-3,4,5-triphosphate, which provides a membrane docking site for protein kinaseB activation. PI3K catalytic p110 subunits are divided into 4 isoforms; α,β,δ and γ. The PI3Kδ isoform is always expressed in AML cells, whereas the frequency of PI3Kγ expression is highly variable. The functions of these individual catalytic enzymes have not been fully resolved in AML, therefore using the PI3K p110δ and p110γ-targeted inhibitor IPI-145 (duvelisib) and specific p110δ and p110γ shRNA, we analysed the role of these two p110 subunits in human AML blast survival...

Constitutive or mutational activation of the phosphatidylinositol 3 kinase, or PI3K, has been implicated in many cancers, including chronic lymphocytic leukemia (CLL). The δ isoform of the p110 catalytic subunit of PI3K has its primary physiologic function in B cells and appears to be the predominant mediator of most PI3K signals in CLL cells. Idelalisib is a first-in-class inhibitor of the PI3K delta isoform that shows near complete inhibition of AKT phosphorylation in CLL cells in vitro and in vivo. Idelalisib shows the classic pattern of response to BCR inhibition in CLL, with rapid nodal response and transient increase in lymphocytosis...

Novel insights into molecular mechanisms have altered our understanding of the pathogenesis of autoimmune skin disorders. Cutaneous lupus erythematosus (CLE) is an autoimmune skin disease characterized by auto-aggressive skin inflammation which histologically presents with interface dermatitis. This inflammation is driven by interferon (IFN)-regulated proinflammatory cytokines that orchestrate the B- and T-cell mediated lesional inflammation. During the last years, therapeutic strategies have focused on these players: biologicals targeting type I IFNs and their receptors as well as anti-B-cell drugs have been investigated in clinical trials with variable success...

Chronic lymphocytic leukemia (CLL) is the most common adult lymphoproliferative disorder in Western countries. The current standard of care for CLL is chemoimmunotherapy, typically with fludarabine, cyclophosphamide, and rituximab (FCR). However, most patients with CLL are elderly with comorbidities and are unable to tolerate FCR. In order to choose the best treatment for each individual patient, physicians must balance efficacy with toxicity. In addition, most currently available treatments are ineffective in CLL patients with loss of TP53...

INTRODUCTION: Over the last few years, several new immunological drugs, particularly monoclonal antibodies (mAbs), immunomodulatory drugs and B-cell receptor (BCR) pathway inhibitors have been developed and investigated in chronic lymphocytic leukemia (CLL). This article summarizes recent discoveries regarding their mechanism of action, pharmacological properties, clinical activity and toxicity, as well as the emerging role of these agents in CLL. AREAS COVERED: A literature review of mAbs, BCR pathway inhibitors and immunomodulating drugs was conducted of the MEDLINE database via PubMed for articles in English...

The functional relevance of the B-cell receptor (BCR) and the evolution of protein kinases as therapeutic targets have recently shifted the paradigm for treatment of B-cell malignancies. Inhibition of p110δ with idelalisib has shown clinical activity in chronic lymphocytic leukemia (CLL). The dynamic interplay of isoforms p110δ and p110γ in leukocytes support the hypothesis that dual blockade may provide a therapeutic benefit. IPI-145, an oral inhibitor of p110δ and p110γ isoforms, sensitizes BCR-stimulated and/or stromal co-cultured primary CLL cells to apoptosis (median 20%, n=57; P<0...

Pharmacological inhibition of phosphatiylinositide-3-kinase (PI3K)-mediated signaling holds great promise for treating chronic lymphocytic leukemia (CLL). Therefore we assessed three structurally related PI3K inhibitors targeting the PI3K-δ isoform for their ability to inhibit the survival of freshly isolated CLL cells. The purely PI3K-δ-selective inhibitor idelalisib was compared to copanlisib (BAY 80-6946) and duvelisib (IPI-145), with isoform target profiles that additionally include PI3K-α or PI3K-γ, respectively...
