Abstract
Idelalisib, a phosphoinositide 3-kinase delta (PI3Kδ) inhibitor, effectively treats relapsed chronic lymphocytic leukemia (CLL). While this targeted approach offers a therapeutic edge, particularly in B-cell malignancies, it is associated with complications such as pneumonitis. This report details idelalisib-induced pneumonitis, highlighting the importance of early diagnosis and tailored treatment in achieving a favorable patient outcome.

Contributions of cancer treatment, comorbidities, and obesity to aging-related disease risks among non-Hodgkin lymphoma survivors. Cancer Causes Control 2023; 34:171-180. [PMID: 36414860 DOI: 10.1007/s10552-022-01652-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Accepted: 11/01/2022] [Indexed: 11/24/2022]
Abstract
PURPOSE It is unknown whether cancer treatment contributes more to long-term disease risk than lifestyle factors and comorbidities among B-cell non-Hodgkin lymphoma (B-NHL) survivors. METHODS B-NHL survivors were identified in the Utah Cancer Registry from 1997 to 2015. Population attributable fractions (PAF) were calculated to assess the role of clinical and lifestyle factors for six cardiovascular, pulmonary, and renal diseases. RESULTS Cancer treatment contributed to 11% of heart and pulmonary conditions and 14.1% of chronic kidney disease. Charlson Comorbidity Index (CCI) at baseline contributed to all six diseases with a range of 9.9% of heart disease to 26.5% of chronic kidney disease. High BMI at baseline contributed to 18.4% of congestive heart failure and 7.9% of pneumonia, while smoking contributed to 4.8% of COPD risk. CONCLUSION Cancer treatment contributed more to heart disease, COPD, and chronic kidney disease than lifestyle factors and comorbidities among B-NHL survivors. High BMI at baseline contributed more to congestive heart failure and pneumonia than cancer treatment, whereas smoking at baseline was not a major contributor in this B-NHL survivor cohort. Baseline comorbidities consistently demonstrated high attributable risks for these diseases, demonstrating a strong association between preexisting comorbidities and aging-related disease risks.

Wien Klin Wochenschr 2020; 133:26-31. [PMID: 32876741 DOI: 10.1007/s00508-020-01729-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Accepted: 08/03/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND The selective PI3K (Phosphatidylinositol 3-kinase) inhibitor HS-173 has anticancer activity in non-small cell lung cancer and pancreatic cancer cells. Of all head and neck squamous cell carcinomas (HNSCC) 20% harbor specific mutations in the genome. The aim of this study was to investigate the effect of HS-173 on HNSCC cell lines. METHODS The cell lines SCC25, CAL27 and FaDu were incubated with HS-173. Its antiproliferative effect was determined using the CCK‑8 cell proliferation assay. Combined incubation with cisplatin was performed and combination index analysis was conducted. To investigate its effect on radiotherapy, cells were irradiated with 2, 4, 6 and 8 Gy, respectively. Synergistic effects of radiation and HS-173 were measured by proliferation assays and clonogenic survival. RESULTS The use of HS-173 induced significant reduction of cell proliferation across all cell lines. Most interestingly, it showed a synergistic effect with cisplatin treatment. Clonogenic survival revealed a radiosensitizing effect in CAL27 and FaDu cells. The HS-173 caused significant induction of apoptosis in SCC25 and FaDu cells. CONCLUSION The selective PI3K inhibitor HS-173 is a potent chemosensitizing and also radiosensitizing drug in treatment of HNSCC cell lines and could be an effective treatment in PI3K-mutated HNSCC.

Resistance to BTK inhibition by ibrutinib can be overcome by preventing FOXO3a nuclear export and PI3K/AKT activation in B-cell lymphoid malignancies. Cell Death Dis 2019; 10:924. [PMID: 31801949 PMCID: PMC6892912 DOI: 10.1038/s41419-019-2158-0] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 10/25/2019] [Accepted: 10/31/2019] [Indexed: 02/06/2023]
Abstract
Chronic activation of the Bruton’s tyrosine kinase (BTK)-mediated B-cell receptor (BCR) signaling is a hallmark of many B-cell lymphoid malignancies, including chronic lymphocytic leukemia (CLL) and diffuse large B-cell lymphoma (DLBCL). Ibrutinib, an FDA approved, orally administered BTK inhibitor, has demonstrated high response rates, however, complete responses are infrequent and acquired resistance to BTK inhibition can emerge. In this study, we generated ibrutinib-resistant (IB-R) cell lines by chronic exposure of CLL and activated B-cell (ABC)-DLBCL cells to ibrutinib in order to investigate the mechanism of acquired resistance to ibrutinib. IB-R cell lines demonstrated downregulation of FOXO3a and PTEN levels and activation of AKT, with their levels being low in the nuclei of resistant cells in comparison to the sensitive counterparts. Inhibition of PI3K and AKT using idelalisib and MK2206, respectively increased ibrutinib-induced apoptosis in IB-R cells by downregulation of pAKT473 and restoring FOXO3a levels, demonstrating the importance of these cell survival factors for ibrutinib-resistance. Notably, the exportin 1 inhibitor, selinexor synergized with ibrutinib in IB-R cells and restored nuclear abundance of FOXO3a and PTEN, suggesting that nuclear accumulation of FOXO3a and PTEN facilitates increase in ibrutinib-induced apoptosis in IB-R cells. These data demonstrate that reactivation of FOXO3a nuclear function enhances the efficacy of ibrutinib and overcomes acquired resistance to ibrutinib. Together, these findings reveal a novel mechanism that confers ibrutinib resistance via aberrant nuclear/cytoplasmic subcellular localization of FOXO3a and could be exploited by rational therapeutic combination regimens for effectively treating lymphoid malignancies.

Abstract
The improved knowledge of pathogenetic mechanisms underlying lymphomagenesis and the discovery of the critical role of tumor microenvironments have enabled the design of new drugs against cell targets and pathways. The Food and Drug Administration (FDA) has approved several monoclonal antibodies (mAbs) and small molecule inhibitors (SMIs) for targeted therapy in hematology. This review focuses on the efficacy results of the currently available targeted agents and recaps the main ongoing trials in the setting of mature B-Cell non-Hodgkin lymphomas. The objective is to summarize the different classes of novel agents approved for mature B-cell lymphomas, to describe in synoptic tables the results they achieved and, finally, to draw future scenarios as we glimpse through the ongoing clinical trials. Characteristics and therapeutic efficacy are summarized for the currently approved mAbs [i.e., anti-Cluster of differentiation (CD) mAbs, immune checkpoint inhibitors, chimeric antigen receptor (CAR) T-cell therapy, and bispecific antibodies] as well as for SMIs i.e., inhibitors of B-cell receptor signaling, proteasome, mTOR BCL-2 HDAC pathways. The biological disease profiling of B-cell lymphoma subtypes may foster the discovery of innovative drug strategies for improving survival outcome in lymphoid neoplasms, as well as the trade-offs between efficacy and toxicity. The hope for clinical advantages should carefully be coupled with mindful awareness of the potential pitfalls and the occurrence of uneven, sometimes severe, toxicities.

Emerging role of BCR signaling inhibitors in immunomodulation of chronic lymphocytic leukemia. Blood Adv 2017; 1:1867-1875.

Abstract
Approved therapies that target the B-cell receptor (BCR) signaling pathway, such as ibrutinib and idelalisib, are known to show activity in chronic lymphocytic leukemia (CLL) via their direct effects on crucial survival pathways in malignant B cells. However, these therapies also have effects on T cells in CLL by mediating toxicity and possibly controlling disease. By focusing on the effects of BCR signaling inhibitors on the T-cell compartment, we may gain new insights into the comprehensive biological outcomes of systemic treatment to further understand mechanisms of drug efficacy, predict the toxicity or adverse events, and identify novel combinatorial therapies. Here, we review T-cell abnormalities in preclinical models and patient samples, finding that CLL T cells orchestrate immune dysfunction and immune-related complications. We then continue to address the effects of clinically available small molecule BCR signaling inhibitors on the immune cells, especially T cells, in the context of concomitant immune-mediated adverse events and implications for future treatment strategies. Our review suggests potentially novel mechanisms of action related to BCR inhibitors, providing a rationale to extend their use to other cancers and autoimmune disorders.

Abstract
B-cell lymphoma-2 (BCL-2) family dysfunction and impairment of apoptosis are common in most B-cell lymphoid malignancies. Venetoclax (Venclexta™, formerly ABT-199, GDC-0199) is a highly selective BCL-2 inhibitor, which mimics its BCL-2 homology 3-domain to induce apoptosis. It was approved for treatment of previously treated chronic lymphocytic leukemia (CLL) patients with 17p deletion early in 2016. It has also been in clinical trials for other B-cell lymphoid malignancies. Unlike the other recently approved targeted agents idelalisib and ibrutinib, so far there has been no relapse reported in some patients. Also, unlike the other targeted agents, it is effective against tumor cells that reside in the blood marrow. Despite its promising outcome in CLL, preclinical data have already uncovered mechanistic insights underlying venetoclax resistance, such as upregulation of MCL-1 or BCL-xL expression and protective signaling from the microenvironment. In this review, we describe the role of the BCL-2 family in the pathogenesis of B-cell lymphoid malignancies, the development of venetoclax, and its current clinical outcome in CLL and other B-cell malignancies. We also discuss the resistance mechanisms that develop following venetoclax therapy, potential strategies to overcome them, and how this knowledge can be translated into clinical applications.

Idelalisib-induced colitis and skin eruption mimicking graft-versus-host disease. Clin J Gastroenterol 2016; 10:142-146.

Abstract
INTRODUCTION Idelalisib is a selective inhibitor of the delta isoform of phosphatidylinositol 3-kinase which was approved by the United States Federal Drug Administration in 2014 for the treatment of relapsed chronic lymphocytic leukemia and indolent non-Hodgkin lymphoma. Drug-induced injury of the gastrointestinal tract is a relatively frequent but usually under-recognized disease entity. CASE PRESENTATION We report the case of a 56-year-old male with a history of relapsed follicular lymphoma status post allogenic bone marrow transplant who developed severe diarrhea with a skin eruption mimicking graft-versus-host disease (GVHD) 6 months after starting idelalisib. He underwent a colonoscopy demonstrating a grossly normal-appearing colon and terminal ileum. Biopsies taken during the procedure revealed mild active ileitis, colitis, and proctitis with frequent epithelial apoptosis, and focal intra-epithelial lymphocytosis. Skin biopsies revealed sub-acute spongiotic dermatitis suggestive of either contact dermatitis or an eczematous drug reaction. Symptoms were attributed to idelalisib given their resolution with withdrawal of the drug in conjunction with the skin and colonic biopsies. CONCLUSION High clinical suspicion and awareness of the histological features of idelalisib-associated colitis is important to distinguish it from potential mimickers such as GVHD and infectious colitis.
