Novel therapeutic strategies are needed to improve the efficacy of chimeric antigen receptor (CAR) T cells as a treatment of solid tumors. Multiple tumor microenvironmental factors are thought to contribute to resistance to CAR T-cell therapy in solid tumors, and appropriate model systems to identify and examine these factors using clinically relevant biospecimens are limited. In this study, we examined the activity of B7-H3-directed CAR T cells (B7-H3.

Background: We sought consensus among practising respiratory physicians on the prediction, identification and monitoring of progression in patients with fibrosing interstitial lung disease (ILD) using a modified Delphi process.

Methods: Following a literature review, statements on the prediction, identification and monitoring of progression of ILD were developed by a panel of physicians with specialist expertise. Practising respiratory physicians were sent a survey asking them to indicate their level of agreement with these statements on a binary scale or 7-point Likert scale (- 3 to 3), or to select answers from a list.

Article Synopsis
  • FGFR inhibitors have shown promise in treating FGFR-altered cholangiocarcinoma, but acquired resistance poses a challenge to their effectiveness.
  • The study utilized diverse investigative methods, including DNA analysis and tissue biopsies, to explore resistance mechanisms in a cohort of patients.
  • Results indicated that a significant number of patients with clinical benefits had specific FGFR2 mutations, but polyclonal resistance was influenced by low drug concentrations and specific mutation types affecting drug efficacy.

Background: Chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF) are debilitating diseases associated with divergent histopathological changes in the lungs. At present, due to cost and technical limitations, profiling cell types is not practical in large epidemiology cohorts (n > 1000). Here, we used computational deconvolution to identify cell types in COPD and IPF lungs whose abundances and cell type-specific gene expression are associated with disease diagnosis and severity.

Article Synopsis
  • - The study explored the risk factors and consequences of acute exacerbations in patients with progressive fibrosing interstitial lung diseases (ILDs), using data from the INBUILD trial, which involved treatments with nintedanib versus placebo.
  • - Results showed that 8.7% of patients experienced acute exacerbations, with lower lung function and older age being significant risk factors, while nintedanib treatment seemed to reduce the risk of these events.
  • - The analysis indicated that acute exacerbations are linked to high mortality rates, with approximately 19% of patients at risk of death within 30 days following such events.

Article Synopsis
  • The introduction of immune checkpoint blockade (ICB) has greatly improved treatment outcomes for advanced melanoma, but many patients still become resistant to it due to unclear reasons.
  • Although combining different ICB therapies has been shown to enhance response rates, it also comes with increased toxicity for patients.
  • An analysis of tumor samples from ICB-naïve patients revealed that high genomic heterogeneity and low ploidy can identify those who are intrinsically resistant to aPD-1, leading to a predictive model that may help tailor treatment strategies.

Purpose: Amplification of cyclin-dependent kinase 4 (CDK4) and CDK6 is a feature of a variety of malignancies, and preclinical evidence suggests that inhibition of CDK4/6 is a plausible treatment strategy in these tumors. Subprotocol Z1C of the NCI-Molecular Analysis for Therapy Choice trial was designed to evaluate the CDK4/6 inhibitor palbociclib in CDK4- or CDK6-amplified tumors.

Patients And Methods: Patients had a solid malignancy or lymphoma with progression on at least one systemic therapy for advanced disease or with no standard-of-care therapy available.

Unlabelled: While a subset of patients with metastatic melanoma achieves durable responses to immune checkpoint blockade (ICB) therapies, the majority ultimately exhibit either innate or acquired resistance to these treatments. However, the molecular mechanisms underlying resistance to ICB therapies remain elusive and are warranted to elucidate. Here, we comprehensively investigated the tumor and tumor immune microenvironment (TIME) of paired pre- and post-treatment tumor specimens from metastatic melanoma patients who were primary or secondary resistance to anti-CTLA-4 and/or anti-PD-1/PD-L1 therapies.

Inhaled nitric oxide (iNO) has been shown to result in benefits in moderate to vigorous physical activity (MVPA) in patients with fibrotic interstitial lung disease (f-ILD) receiving supplemental oxygen in two independent trials. This phase III randomized, double-blind, placebo-controlled study sought to validate the benefit of ambulatory iNO in patients with f-ILD requiring supplemental oxygen. Patients with f-ILD receiving supplemental long-term oxygen were randomized in a 1:1 fashion to iNO at 45 μg/kg ideal body weight per hour or placebo for 16 weeks.

Advances in anticancer therapies have provided crucial benefits for millions of patients who are living long and fulfilling lives. Although these successes should be celebrated, there is certainly room to continue improving cancer care. Increased long-term survival presents additional challenges for determining whether new therapies further extend patients' lives through clinical trials, commonly known as the gold standard endpoint of overall survival (OS).

Article Synopsis
  • - This study evaluated the safety and effectiveness of Debio 1347, a new oral drug targeting FGFR fusions in patients with advanced solid tumors, focusing on its ability to produce objective responses and other outcomes in different cancer types.
  • - A total of 63 patients participated, with only a 5% objective response rate, leading to the trial's early termination due to lower-than-expected effectiveness, despite manageable side effects like hyperphosphatemia and stomatitis.
  • - The findings suggest that while the drug has some tolerance, its lack of significant efficacy means it should not undergo further testing for FGFR fusion tumors; the study also provided insight into the characteristics of FGFR fusions in solid tumors.
