Based on historical and recent evidences of anti-inflammatory effects of low dose of ionizing radiation, several healthcare professionals proposed low-dose radiation therapy (LDRT) along with ongoing pharmacological treatment for COVID-19 pneumonia. A positive response in a few initial studies led to systematic trials by increasing the number of patients in the range of 0.5–1.5 Gy. However, the concerns of radiation-induced risks were also raised in parallel. In the present article, we have highlighted the basis of LDRT for COVID-19 therapy. We have reviewed the available literature, specifically for outcomes on various clinical trials carried out with LDRT. Meta-analysis was performed to identify if any survival benefits are offered by addition of LDRT over pharmacological treatment alone among COVID-19 pneumonia patients. Other clinical recovery parameters such as intubation rates, oxygenation status, anti-inflammatory response have also been compared. Overall data trends favored LDRT with standard pharmacological treatment against control cohort which received standard treatment alone at all the endpoints in majority studies. LDRT addition resulted in significantly higher odds of survival than control cohort. Among critical and/or mechanically ventilated patients, LDRT did not show any promising outcomes over the control group. In conclusion, LDRT may serve as a promising complementary treatment modality with a potential of better prognosis, provided the patient selection criteria are critically identified and implemented.</p>","PeriodicalId":50610,"journal":{"name":"Cts-Clinical and Translational Science","volume":"18 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cts.70137","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The botanical product goldenseal was previously shown to decrease metformin systemic exposure in healthy adults. This three-arm, open-label, crossover clinical study assessed the pharmacokinetic goldenseal–metformin interaction in adults with type 2 diabetes stabilized on therapeutic doses of metformin (500–2550 mg daily). The aggregate pharmacokinetic data indicated no clinically meaningful interaction as determined by the metformin area under the plasma concentration-time curve (AUC) geometric mean ratio [90% confidence interval] of 0.93 [0.86–1.01] laying within the predefined no-effect range (0.80–1.25). However, metformin AUC decreased by ~20%, 14%, and 0% after goldenseal coadministration at low (500–750 mg), moderate (1000–1500 mg), and high (2000–2550 mg) metformin doses, respectively; renal clearance and half-life remained unchanged throughout. The exploratory pharmacodynamic endpoint, HbA1c, decreased on average from 6.8% to 6.5%, regardless of the effects of goldenseal on metformin pharmacokinetics. The decreasing effect of goldenseal on metformin systemic exposure with increasing metformin dose, coupled with no changes in renal excretion and elimination half-life, indicated that both the pharmacokinetic goldenseal–metformin interaction and the nonlinear absorption of metformin are governed by saturable, intestinal transport mechanism(s). The disconnect between changes in metformin systemic exposure and therapeutic effects emphasizes the need to evaluate clinical biomarkers to comprehensively assess drug interaction risks, particularly those involving natural products. Healthcare providers may consider cautioning patients about supplementing metformin pharmacotherapy with goldenseal to avoid risks for undesired changes in glycemic control.</p><p><b>Trial Registration:</b> ClinicalTrials.gov identifier: NCT05081583</p>","PeriodicalId":50610,"journal":{"name":"Cts-Clinical and Translational Science","volume":"18 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cts.70120","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143396787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent observations have revealed significant pharmacological effects of CD19 CAR-T cells in patients with systemic lupus erythematosus (SLE), suggesting promising applications in other autoimmune conditions. Consequently, as of December 2024, there are 116 different clinical trials evaluating CAR-T cells against autoimmune conditions. While the field is starting to understand the overall pharmacological actions of CAR-T cells in autoimmune diseases, the dose-exposure-response relationship remains inadequately characterized due to limited clinical data. To address these uncertainties, we have developed a Quantitative Systems Pharmacology (QSP) model using short-term limited clinical data of anti-CD19 CAR-Ts in autoimmune disease patients (<i>n</i> = 5), followed by a model qualification step utilizing an external dataset (<i>n</i> = 13). The developed QSP model integrated and effectively characterized the (1) cellular kinetics of different immunophenotypic population of CAR-T cells, (2) impact of lymphodepletion chemotherapy on host immune cells, (3) CAR-mediated elimination of CD19+ B-cells and (4) dynamic changes in disease surrogate biomarkers and its relationship with clinical score. The key pharmacological biomarkers which were incorporated within the QSP model included anti double stranded DNA (anti-dsDNA) antibodies, proteinuria, C3 protein and IFN-alpha. Later, a linear regression analysis-based relationship was developed between continuous disease biomarkers and the categorical SLE disease activity index (SLE-DAI) determined by the investigators offering a predictive framework for disease progression in SLE patients. This proposed QSP model holds potential to elucidate quantitative pharmacology and expedite clinical advancement of autologous and allogeneic cell therapies in autoimmune diseases.</p>","PeriodicalId":50610,"journal":{"name":"Cts-Clinical and Translational Science","volume":"18 2","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cts.70146","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
