Small molecular fluorescence dyes for immuno cell analysis.

ABSTRACT: Many diseases, including cancers, AIDS, diabetes, asthma, Parkinson's, and lymphoma, are associated with the immune cell responses of patients suffering from them. Identifying the underlying immune response in such diseases is critical to correctly diagnose their root cause and determine the correct medications to target that root cause for personal therapy and immunotherapy. This work focuses on small molecular CF dyes to conjugate with antibodies, such as CD4 and CD19, for their application in flow cytometry. The CF dyes enable the expansion of flow cytometry reagent panels to support high dimensional flow cytometry analysis of the resulting emissions of 30-40 fluorescent colors, a record in flow cytometry. The CF dyes can be used along with existing flow cytometry dyes to provide a quick, accurate, and cost-effective method for the diagnosis and immunology treatment of diseases such as minimal residual disease (MRD) after cancer therapy. The CF dyes will also be an effective tool for the clinical studies of immune response to SARS-CoV-2 and the related vaccine development.

Project description:IntroductionMany randomized controlled trials have indicated that immuno-chemotherapy could generate clinical benefits, though the cost of immuno-chemotherapy was so prohibitive and the options were varied. This investigation aimed at evaluating effectiveness, safety, and cost-effectiveness for immuno-chemotherapy as a first-line therapeutic option for ES-SCLC patients.MethodsMultiple scientific literature repositories were searched for clinical studies where immuno-chemotherapy was regarded as the first-line treatment for ES-SCLC, which were published in English between Jan 1, 2000, and Nov 30, 2021. This study conducted a network meta-analysis (NMA) and cost-effectiveness analysis (CEA) based upon US-resident payer perspectives. Overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were evaluated through NMA. In addition, costings, life-years (LYs), quality-adjusted life-years (QALYs), and incremental cost-benefit ratio (ICER) were estimated by CEA.ResultsWe identified 200 relevant search records, of which four randomized controlled trials (RCTs) (2,793 patients) were included. NMA demonstrated that the effect of atezolizumab plus chemotherapy was ranked at a more elevated position in comparison to other immuno-chemotherapy options and chemotherapy alone, within the general population. The influence of atezolizumab plus chemotherapy and durvalumab plus chemotherapy was ranked higher within populations experiencing non-brain metastases (NBMs) andbrain metastases (BMs), respectively. The CEA revealed that the ICERs of immuno-chemotherapy over chemotherapyalone were higher than the willingness-to-pay (WTP) threshold of $150,000/QALY in any population. However, treatment with atezolizumab plus chemotherapy and durvalumab plus chemotherapy were more favorable health advantages than other immuno-chemotherapy regimens and chemotherapy alone, and the results were 1.02 QALYs and 0.89 QALYs within overall populations and populations with BMs, respectively.ConclusionThe NMA and cost-effectiveness investigation demonstrated that atezolizumab plus chemotherapy could be an optimal first-line therapeutic option for ES-SCLC when compared with other immuno-chemotherapy regimens. Durvalumab plus chemotherapy is likely to be the most favorable first-line therapeutic option for ES-SCLC with BMs.
