There are about 2320 clinical studies being (or have been) conducted in Chile. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of V116 compared to PPSV23 in children 2 through 17 years of age. Researchers want to learn if V116 is as good as, or is better than the PPSV23 vaccine in terms of the antibody immune response. V116 and PPSV23 will be studied in children and teenagers who have a higher risk of getting invasive pneumococcal disease (IPD).
Post-herpetic neuralgia (PHN) is the most frequent complications related to herpes zoster, and can persist for months or even years, and require extensive treatment. For this purpose, pharmacological therapies based on tricyclic antidepressants (amitriptyline), central nervous system depressants (pregabalin) and also opioids, have been stablished. However, all the drugs mentioned can cause serious systemic adverse effects that worsen the patient's quality of life. To avoid these complications, topical therapies based on Capsaicin or Lidocaine 5% patches have been developed. However, these treatments have shown dissimilar results in controlling PHN, so a mixed formulation of lidocaine/tetracaine could show better results. For these reasons, the main objective of our work is to evaluate the plasma levels of lidocaine derived from the application of a topical formulation of lidocaine derived from the application of a topical formulation of lidocaine 23%/tetracaine 7% in patients with neuropathic pain.
The primary objective of the study is to compare sacituzumab tirumotecan combined with pembrolizumab to pembrolizumab alone with respect to overall survival (OS). The primary hypothesis is that the combination of sacituzumab tirumotecan and pembrolizumab is superior to pembrolizumab alone with respect to OS. All participants who have completed the first course of pembrolizumab may be eligible for up to an additional 9 cycles of pembrolizumab monotherapy if there is blinded independent central review (BICR)-verified progressive disease by Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) after initial treatment.
The objective of this clinical trial is to know if boldo oral powder capsules works well in the management of urinary symptoms in women with overactive bladder. The main questions it aims to answer are: - Is boldo supplementation safe? - Does boldo improve urinary parameters and body stability? 5 participants will be treated with an oral antimuscarinic (oxybutynin) and supplemented with oral spray bolus. The urinary chart will be applied to measure urinary frequency and voiding intervals. In addition, urinary symptoms and the level of discomfort they generate will be measured. Finally, the MiniBest test will be applied using a portable device which acts as an inertial sensor to record the movements made. For comparative purposes, 5 women who will only be treated with the oral antimuscarinic (oxybutynin) will be measured to see if there are significant differences between the medication alone versus the supplemented medication.
The purpose of this study is to evaluate the efficacy and safety of MK-6194 in adult participants with Systemic Lupus Erythematosus. The primary hypothesis is that at least 1 of the MK-6194 arms is superior to placebo in the primary endpoint of percentage of participants with systemic lupus erythematosus responder index (SRI-4) response at Week 28.
There is no a reliable marker of intraoperative fluid excess or overload. The use of lung ultrasound in other settings, such as emergency room and critical care patients, helps us to determine if a patient has a condition of augmented intrathoracic fluid, that could be related to several circumstances, such as fluid overload, but also to heart failure, in example. Nevertheless, there is no information regarding the basal incidence of this finding, to ascertain if could be eventually used as a potential marker of fluid overload. This protocol looks for the incidence of the finding of B-Lines, which are related to fluid overload, in patients undergoing open abdominal surgery.
This prospective placebo-controlled trial will enroll 20 patients with SSc and at least one calcinotic lesion of the hands that is palpable on physical examination and measurable on hand radiographs. Each subject will undergo a screening evaluation 1 month before treatment with the study drug is initiated. Each subject will be instructed to blindly self-apply either topical 25% sodium metabisulfite or placebo cream twice daily. In-person follow-up evaluations will be performed after 4-months, with monthly telehealth follow-up visits to ensure adherence and arrange study drug refill deliveries.
Implementing this protocol has its ethical justification in that patients with metastatic melanoma, once tumor invasion has reached beyond the lymph node barrier, cannot possibly be treated satisfactorily with traditional surgery methods, radiotherapy, or conventional available chemotherapy. The disseminated tumor is refractory to all standard treatments. Almost 100% of patients who develop distant metastases will die from their disease, either from complications or cachexia. Therefore, immunotherapy based on immunological stimulation with immunocompetent dendritic cells, added to immunological reinforcement with IL-2, can, according to the evidence emanating from ongoing clinical protocols, produce a prolongation of survival with better quality and, in some cases, with partial or total regression of the tumor. General objective: It is to study the clinical and immunological response of patients treated with vaccines based on autologous dendritic cells loaded with tumor antigens, derived from allogeneic melanoma extracts, in combination or not, with intercalated low doses of recombinant human interleukin 2 (rhIL2) PROLEUKIN ® (aldesleukin). MAIN SPECIFIC OBJECTIVE: - SAFETY: Safety in administering dendritic cell preparation; local and systemic toxicity estimation. Determination of adverse reactions such as fever, nausea, allergy, neurological and cardiovascular symptoms. Local toxicity in the administration area. - MEASUREMENT OF THE IMMUNE RESPONSE: Based on in vivo and in vitro parameters: - In vivo response: Measure the type IV Delayed Hypersensitivity (DTH) response. It consists of a crossover test in which the response is compared to tissue interaction in vivo between dendritic cells sensitized with tumor extracts and their respective control unloaded dendritic cells. - In vitro response: ELISPOT assays, measurement of IFN-γ gamma production in peripheral blood of treated patients. Compare the specific immune response after each cycle of therapy through measurement of IFN-γ production by tumor-specific CTL. Cytotoxic radioactive chromium release assays to measure anti-tumor response mediated by CTL and NK. ELISA assays for quantifying cytokines (IFN-γ, IL-10) in patient serum after each cycle of therapy.
The goal of this prospective, double blind randomized clinical trial is to compare the effectiveness of two interventions in improve frailty (measured by Liver Frailty Index) and quality of life (measured by Chronic Liver Disease Questionnaire - CLDQ) in listed patients with cirrhosis. The main questions it aims to answer are: - if the intervention group (physical and nutritional therapy) could improve LFI over control group (physical and nutritional counseling). - if the intervention group could improve secondary outcomes as CLDQ, hand grip and gait velocity. Participants will be evaluated in a registry of basal variables such as demographic factors, weight, height and brachial circumference, comorbidities, MELD and MELD-Na, Child Pugh classification, general blood exams, etiology of cirrhosis, presence of hepatocellular carcinoma, ascites, or hepatic encephalopathy and their basal LFI, gait velocity, hand grip and CLDQ. The participants will be randomized in an intervention group or in a control group at the same time of their first evaluation and will receive the group instructions depending on what group the participants belong, and will be evaluated at 4 weeks, 8 weeks, and 12 weeks with applying LFI, measuring of gait velocity, hand grip and a nutritional survey with the intake in the last 24 hours. Finally, researchers will compare interventional group with control group if the first group could improve frailty, measured by Liver Frailty Index and the secondary outcomes with the nutritional and physical therapy.
Trismus has been reported as the second most common comorbidity in survivors of head and neck cancer (HNC). It is mainly associated with post-radiotherapy subcutaneous fibrosis, muscular atrophy, damage to neurological structures in the neck, or a combination of all, affecting masticatory musculature. In addition to this, the loss of flexibility and strength in the shoulder has also been shown to be related to deficits in the function and quality of life of these patients. The goal of this clinical trial is to determinate the effectiveness and safety of Manual Therapy (MT) on oral health, as well as the mobility of the upper quarter, the strength of cervical musculature, pain, functionality, and the perception of quality of life in head and neck cancer survivors. Participants will be assigned randomly to the study groups: a) manual therapy program and control motor exercises, b) control motor exercises (usual care) and, c) waiting list. The assessment refers to a baseline form (at the beginning of the study), at 6 weeks and at 6 weeks of patient follow-up.
