NCT ID: NCT05920148 Recruiting - Aging Clinical Trials

The Immu-KNEE-ty Study

Start date: March 12, 2024
Phase:
Study type: Observational

The goal of this observational study is to determine changes in immune functioning after total knee replacement surgery in elderly. The study population consists of 14 patients aged 65 years or over undergoing primary total knee replacement surgery. Immune functioning will be assessed at multiple timepoints before and after surgery (i.e., ± 6 weeks before, and 1 day, 1 week, ± 2 weeks, and ± 6 weeks after surgery). Each patient will serve as his/her own control. Immune functioning will primarily be assessed by determining the change from baseline in monocyte-derived TNFα production at 1 week after surgery. Changes in monocyte responsiveness are considered indicative for changes in immune functioning. As secondary objective, additional parameters of immune functioning will be assessed. In addition, the course of immune functioning following total knee replacement surgery will be investigated. Burden and potential risks for the patient are estimated to be minor. During the study, 5 blood samples of 20 mL will be collected over a period of ± 12 weeks, resulting in a total blood draw of 100 mL. During surgery a sample of synovial fluid (± 2 mL) will be taken from surgical waste. Before and after surgery patients will report their pain medication intake and the presence of cold and flu-like symptoms in a diary. Patients do not directly benefit from the study.

NCT ID: NCT05322343 Recruiting - Depression Clinical Trials

Biobank and Brain Health in Bordeaux.

B-cube
Start date: March 22, 2022
Phase:
Study type: Observational [Patient Registry]

B cube is a new generation cohort to study the determinants and natural history of brain aging, using molecular epidemiology, in a representative sample (N=2000) of the general population from the age of 55 (the approximate age of onset of the first cognitive disorders and a target population particularly receptive to prevention messages). Special interest will be given to nutrition, a promising environmental exposure for prevention.

NCT ID: NCT04375657 Recruiting - Immunosenescence Clinical Trials

Thymus Regeneration, Immunorestoration, and Insulin Mitigation Extension Trial

TRIIM-X
Start date: November 23, 2020
Phase: Phase 2
Study type: Interventional

The TRIIM-X trial is an expanded pilot clinical study that will evaluate a personalized combination treatment regimen for thymus regeneration. The thymus is a part of the immune system that declines markedly with age, and regenerating it may prevent or reverse key aspects of immunosenescence (immune system aging) and potentially prevent or reverse key parts of the aging process more generally. The study will evaluate biomarkers for epigenetic aging and immunosenescence, as well as evaluate established clinical measures and risk factors for prevention of physical frailty, cancer, cardiovascular disease, diabetes, dementia, and also infectious diseases, including flu and COVID-19. The study uses multiple agents in combination with personalized doses of recombinant human growth hormone (somatropin), metformin, and DHEA, in a similar manner to how the combination treatment was applied in the earlier TRIIM trial at Stanford, which demonstrated strong statistical significance for the primary efficacy endpoints that will be evaluated in TRIIM-X. Somatropin is approved by the FDA for adult growth hormone deficiency and its use in the study is guided by prior safety data established for that use and also based on safety data available on its prior use in the TRIIM trial and in clinical practice in healthy elderly individuals. There will also be control groups that enable testing of biomarker variability and the contribution of individual medications within the combination treatment. The objective of the study is to obtain information needed for designing an effective personalized and adaptive treatment regimen for a larger and more diverse study population, and to obtain additional proof of principle for the new use of the medications and biomarkers for preventive medicine. The duration of treatment in the TRIIM-X trial will be 12 months.
