TL;DR: A major unmet need is the identification of biomarkers that can predict response to therapy and facilitate a personalized therapeutic approach, which maximizes the benefits and limits the adverse events.
Abstract: Introduction: Although the etiology of inflammatory bowel diseases (IBD) remains unknown, accumulating evidence suggests that the intestinal tissue damage in these disorders is due to a dynamic interplay between immune cells and non-immune cells, which is mediated by cytokines produced within the inflammatory microenvironment. Areas covered: We review the available data about the role of inflammatory cytokines in IBD pathophysiology and provide an overview of the therapeutic options to block the function of such molecules. Expert opinion: Genome studies, in vitro experiments with patients' samples and animal models of colitis, have largely advanced our understanding of how cytokines modulate the ongoing mucosal inflammation in IBD. However, not all the cytokines produced within the damaged gut seem to play a major role in the amplification and perpetuation of the IBD-associated inflammatory cascade. Indeed, while some of the anti-cytokine compounds are effective in some subgroups of IBD patients, others have no benefit. In this complex scenario, a major unmet need is the identification of biomarkers that can predict response to therapy and facilitate a personalized therapeutic approach, which maximizes the benefits and limits the adverse events.

TL;DR: Targeted BCMA-based immunotherapies used earlier in the disease course and in combination have great promise to achieve long-term disease control and potential cure.
Abstract: Introduction: B cell maturation antigen (BCMA) contributes to MM pathophysiology and is a target antigen for novel MM immunotherapy. Complete responses have been observed in heavily pretreated MM patients after treatment with BCMA antibody-drug conjugates (ADC), chimeric antigen receptor T, and bi-specific T cell engagers (BiTE®). These and other innovative BCMA-targeted therapies transform the treatment landscape and patient outcome in MM. Areas covered: The immunobiological rationale for targeting BCMA in MM is followed by key preclinical studies and available clinical data on efficacy and safety of therapies targeting BCMA from recent phase I/II studies. Expert opinion: BCMA is the most selective MM target antigen, and BCMA-targeted approaches have achieved high responses even in relapse and refractory MM as a monotherapy. Long-term follow-up and correlative studies using immuno-phenotyping and -sequencing will delineate mechanisms of overcoming the immunosuppressive MM bone marrow microenvironment to mediate additive or synergistic anti-MM cytotoxicity. Moreover, they will delineate cellular and molecular events underlying the development of resistance underlying relapse of disease. Most importantly, targeted BCMA-based immunotherapies used earlier in the disease course and in combination (adoptive T cell therapy, mAbs/ADCs, checkpoint and cytokine blockade, and vaccines) have great promise to achieve long-term disease control and potential cure.

TL;DR: SVF provides a cellular and molecular microenvironment for regulation of ASC’ activities under different clinical conditions and novel point of care methods are emerging to refine SVF in ways that meet the regulatory requirements for minimal manipulation.
Abstract: Introduction: The heterogeneous pool of cells found in the stromal vascular fraction of adipose tissue (SVF) and the purified mesenchymal stromal/stem cells (ASCs) isolated from this pool have increasingly been used as therapeutic tools in regenerative medicine.Areas covered: As SVF and ASCs are different, and should be used in different manners according to various clinical and biological indications, we reviewed the current literature, and focused on the clinical use of SVF to appraise the main medical fields for development. Both enzymatic digestion and mechanical disruption have been used to obtain SVF for non-homologous use. The safety and/or benefits of SVF have been examined in 71 clinical studies in various contexts, mainly musculoskeletal conditions, wound healing, urogenital, and cardiovascular and respiratory diseases. The use of SVF as a therapy remains experimental, with few clinical trials.Expert opinion: SVF provides a cellular and molecular microenvironment for regulation of ASC' activities under different clinical conditions. SVF may enhance angiogenesis and neovascularization in wound healing, urogenital and cardiovascular diseases. In joint conditions, therapeutic benefits may rely on paracrine immune-modulatory and anti-inflammatory mechanisms. Novel point of care methods are emerging to refine SVF in ways that meet the regulatory requirements for minimal manipulation.

TL;DR: Takeaway: All four CGRP mAbs demonstrated an excellent safety, tolerability and efficacy profile in migraine patients and are likely to usher in a new era in migraine prevention and provide significant value to patients.
Abstract: Introduction: Calcitonin Gene-Related Peptide (CGRP) plays a crucial role in migraine pathophysiology. A novel specific treatment strategy for the prevention of migraine incorporates monoclonal antibodies (mAbs) against CGRP and its canonical receptor. Eptinezumab, fremanezumab and galcanezumab block CGRP mediated effects by binding to the peptide, while erenumab blocks the CGRP receptor.Areas covered: Following a brief overview of pharmacological characteristics, we will review phase III trials for the use of CGRP mAbs in the prevention of episodic and chronic migraine.Expert opinion: All four CGRP mAbs demonstrated an excellent safety, tolerability and efficacy profile in migraine patients. Across all trials mAbs showed superior efficacy for the reduction of monthly migraine days compared to placebo with a net benefit of 2.8 days. Neither cardiovascular nor immunological safety concerns have emerged from clinical trials. Fremanezumab, galcanezumab, and erenumab are approved in the USA and Europe. Based on trial data there is no reason why these mAbs should not become first-line therapies in future. For now, we advocate for the use of mAbs in migraine prevention for patients who failed a minimum of two standard oral treatments based on the novelty and costs of this approach. mAbs are also effective in patients with medication overuse and with comorbid depression or anxiety disorders. Taken together, mAbs are likely to usher in a new era in migraine prevention and provide significant value to patients.

TL;DR: Clinical evidence for different immunotherapeutic approaches for NPC is reviewed, including adoptive cellular therapy, therapeutic cancer vaccines, and immune checkpoint inhibitors, and the development of scalable and reproducible immune product generation processes.
Abstract: Introduction: Nasopharyngeal carcinoma (NPC) is endemic in Southern China and Southeast Asia. Epstein-Barr virus (EBV) represents a unique etiological culprit in the poorly differentiated nonkeratinizing and undifferentiated subtypes. EBV antigens are expressed on tumor cells albeit in a restricted manner. Treatment options for recurrent or metastatic disease are limited. Nevertheless, emerging data from immunotherapy studies in NPC have shed light into their potential antitumor efficacy. Areas covered: This article reviews existing clinical evidence for different immunotherapeutic approaches for NPC, including adoptive cellular therapy, therapeutic cancer vaccines, and immune checkpoint inhibitors. Expert opinion: There is a growing understanding on EBV virology and the immune evasion mechanisms in NPC. Immunotherapeutic strategies leveraging these properties have shown encouraging efficacy and safety results in early-phase clinical studies. Moving forward, areas to be addressed include appropriate patient selection, optimal incorporation into standard treatment paradigms, biomarker identification, as well as the development of scalable and reproducible immune product generation processes.

TL;DR: More research is needed to establish its efficacy in different disease stages and applicability in other tumor types, and prospective, randomized trials of durvalumab, alone and/or in combination with other agents, will bring answers to these questions in the near future.
Abstract: Introduction: The U.S. FDA has approved durvalumab for the treatment of advanced urothelial and non-small cell lung cancers. However, this immunotherapy agent is also being explored in other cancers. There is also ongoing research to better predict the responses to this drug. Areas covered: We summarize the literature regarding durvalumab pharmacology, safety and efficacy in several tumor types. We searched PubMed/Medline database from inception to 20 April 2019, performed a snowball method, and visited independent websites such as the U.S. FDA ( https://www.fda.gov ), ClinicalTrials.gov, among others. Expert opinion: Advanced phase clinical trials have shown benefit of durvalumab in advanced urothelial and non-small cell lung cancers, and suggest benefit in several other tumor types. This agent has a tolerable toxicity profile and seems more effective in patients with a higher PDL-1 expression, although this correlation is not perfect. An improved method to predict a response to durvalumab would be beneficial to best tailor therapy and minimize medical care costs. More research is needed to establish its efficacy in different disease stages and applicability in other tumor types. Hopefully, prospective, randomized trials of durvalumab, alone and/or in combination with other agents, will bring answers to these questions in the near future.

TL;DR: The findings for advanced disease and in the pilot phase II study in early-stage colon cancer open a new avenue for the applicability of immunotherapy in neoadjuvant and adjuvant settings, which are currently under investigation.
Abstract: Introduction: Metastatic colorectal cancer (mCRC) is a challenging disease, whose systemic therapy has traditionally been based on a generalized population of patients, with unsatisfactory clinical outcomes. Immunotherapy has been shown to be efficacious in hypermutated tumors, such as those with microsatellite-instability (MSI-H). Nivolumab, and other immune checkpoint inhibitors (ICI), have recently been evaluated in MSI-H mCRC, with remarkable results.Areas covered: Focused on nivolumab, we aim to present the rationale for the applicability of ICI in MSI-H CRC, and the results of completed phase I/II studies. Ongoing studies, including randomized clinical trials, and perspectives of immunotherapy in clinical scenarios in CRC will be discussed.Expert opinion: Phase I and II clinical trials provide strong evidence for the use of nivolumab and other ICI in the systemic therapy of MSI-H mCRC. Regulatory approvals are restricted to subsequent lines of therapy, but preliminary results in treatment-naive patients are encouraging. The findings for advanced disease and in the pilot phase II study in early-stage colon cancer open a new avenue for the applicability of immunotherapy in neoadjuvant and adjuvant settings, which are currently under investigation. With the exception of POLE-mutated patients, there is little evidence for the use of immunotherapy in MSS patients.
