Aim:
In renal cell carcinoma (RCC), tumor heterogeneity generated challenges to biomarker development and therapeutic management, often becoming responsible
Methods:
The RIVELATOR study was a monocenter retrospective analysis of biological samples from 25 cases of primary RCC and their paired pulmonary metastases. The biomarkers analyzed included MET, mTOR, PD-1/PD-L1 pathways and the immune context.
Results:
High multi-level heterogeneity was demonstrated. MET was the most reliable biomarker, with the lowest intratumor heterogeneity: the positive mutual correlation between MET expression in primary tumors and their metastases had a significantly proportional intensity (P = 0.038). The intratumor heterogeneity grade was significantly higher
Conclusions:
In mRCC, multiple and multi-level assays of potentially predictive biomarkers are needed

Lynch syndrome is a hereditary cancer predisposition syndrome caused by germline alterations in mismatch repair (MMR) genes leading to increased risk of colon cancer as well as other cancer types. Non-small cell lung cancer (NSCLC) is not among typical Lynch syndrome-associated tumors: pembrolizumab, an immune checkpoint inhibitor, is actually approved

Aim:
As the primary response antibody with increasing use as a therapeutic immunoglobulin (Ig)
Methods:
Through a panel of 14 recombinant complementarity determining regions (CDRs)-grafted trastuzumab and pertuzumab VH1-7 IgMs subjected to bio-layer interferometry measurements, the interactions with the antigen human epidermal growth factor receptor 2 (Her2), Fc-mu receptor (FcμR), and superantigen Protein L (PpL) were investigated.
Results:
Significant effects from the V-regions to mitigate FcμR binding and the IgM C-region bidirectional effect modulating Her2 antigen engagements at the V-regions were found. Additional modulatory effects from superantigen PpL binding on the V-region of the kappa chain (Vκ) mitigating antigen binding were also found, revealing possible novel mechanisms of antibody superantigens that can be moderated by the antibody VH frameworks.
Conclusions:
These findings show that the oligomerisation of IgMs plays a significant role in FcμR, antigen, and superantigen binding that made IgM distinct from the other antibody isotypes and how these features should be considered during further development and protein engineering of IgM therapeutics.

Aim:
The role of tumor burden (TB)
Methods:
Sixty-five consecutive patients with advanced NSCLC treated with immunotherapy as first or second line therapy were retrospectively analyzed between August 2015 and February 2018. TB was recorded at baseline considering sites and number of metastases, thoracic vs. extrathoracic disease, measurable disease (MD) vs. not-MD (NMD) and evaluating dimensional aspects as maximum lesion diameter (cut-off = 6.3 cm), sum of the 5 major lesions diameters (cut-off = 14.3 cm), and number of sites of metastases (cut-off > 4). All cut-offs were calculated by receiver operating characteristic curves. Median overall survival (OS) was estimated using Kaplan-Meier method. A Cox regression model was carried out
Results:
Median age was 70 years and most patients (86.2%) had a good per
Conclusions:
This study underlines the negative prognostic impact of specific metastatic sites, presence of NMD and extrathoracic disease in advanced NSCLC patients treated with immunotherapy. However, TB does not appear to affect the outcome of these patients.

Aim:
The clinical symptoms of autoantibody (AAb)-mediated autoimmune diseases (AID) usually correlate with the AAb-titer. Immunoglobulins (Igs) of the IgG type are actively recycled by the neonatal crystallizable fragment receptor (FcRn). The most common Ig type of AAb is IgG. This explorative study evaluates the safety and tolerability of a fully human anti-FcRn monoclonal antibody (mAb) in patients with thyroid autoimmunity (TA).
Methods:
Adverse events (AEs) and serious AEs (SAEs) were documented and coded according to the standardized Medical Dictionary
Results:
Of 31 patients with TA, 19 were administered the anti-FcRn mAb subcutaneously once weekly
Conclusions:
The anti-FcRn mAb is a safe and well-tolerated therapy

Methods:
We systematically searched PubMed and ClinicalTrials.Gov databases utilizing specific terms to identify placebo-controlled or head-to-head RCTs (last research on March 1, 2020) involving NAFLD patients with the aim of evaluating the efficacy of GLP-1 RAs to treat NAFLD/NASH. Primary outcomes were changes in serum liver enzymes, liver fat content, or histologic resolution of NASH. Weighted mean differences (WMD) were used to test the differences between the treatment arms.
Results:
Overall, we found 7 placebo-controlled or head-to-head RCTs involving 472 middle-aged individuals (66% men; 77% with established diabetes) followed
