There are about 5012 clinical studies being (or have been) conducted in Mexico. 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 is to evaluate the biomarker effect, safety, and tolerability of investigational study drugs in participants who are known to have an Alzheimer's disease (AD)-causing mutation. Part 1 will determine if treatment with the study drug prevents or slows the rate of amyloid beta (Aβ) pathological disease accumulation demonstrated by Aβ positron emission tomography (PET) imaging. Part 2 will evaluate the effect of early Aβ plaque reduction/prevention on disease progression by assessing downstream non-Aβ biomarkers of AD (e.g., CSF total tau, p-tau, NfL) compared to an external control group from the DIAN-OBS natural history study and the DIAN-TU-001 placebo-treated participants.
A proof-of-concept study of a prototype CloudCath device designed to detect peritonitis using the effluent dialysate from patients undergoing peritoneal dialysis.
This study will evaluate the efficacy, safety, antiviral activity, and pharmacokinetics of study drug RO7496998 (AT-527) compared to placebo in non-hospitalized adult and adolescent participants with mild to moderate coronavirus disease 2019 (COVID-19) in the outpatient setting.
This is a multi-center feasibility study to assess the in vitro function of the CloudCath Device that is being developed to derive clinically-relevant information from the optical characteristics of urine.
Phase III study to evaluate the efficacy and safety of the treatment. Two-arm, prospective, longitudinal, double-blind, multicenter randomized clinical trial.
Dental caries (coronal and root) is highly prevalent in older adults. It is important to identify and implement the most effective methods that prevent the formation of root caries lesions and inhibit existing lesions at the community level. A clinical trial will be conducted in three groups of adults 60 years old and older, comparing the application of silver diamine fluoride solution and sodium fluoride varnish in dental root surfaces with caries and sound root surfaces. The objectives are to determine over a 30-month period which of the two agents is most effective in reducing the incidence of root caries, and which is most effective in arresting active root caries lesions. Hypothesis: the incidence of root caries will be lower in the group of subjects treated with silver diamine fluoride compared to sodium fluoride varnish. The arrest of active root lesions will be higher when using silver diamine fluoride compared to sodium fluoride varnish. Signed informed consent will be requested from persons 60 years and over, residents of four long-term care centers and attendees of a day care center in four central states of Mexico: Mexico City, Cuernavaca City, Oaxaca City and Toluca City. All facilities are administered by the National System for Integral Family Development (IFD), a public welfare institution that works at the federal and state levels. Three groups will be formed (60 participants in each), two groups will be administered each of the agents, the third group will be the control group. All groups will receive dental health education (oral hygiene, instructions for care and hygiene of removable dental prosthesis, information on prevention of coronal and root caries and periodontal diseases). The preventive agents will be administered according to the manufacturer's instructions. Clinical evaluations will be carried out at baseline 6, 12, 18, 24 and 30 months. The incidence of root caries among the groups will be compared with the percentage of active root lesions that were arrested and that remained inactive. If the greater efficacy of silver diamine fluoride is proven, it can be proposed for use in caries preventive programs for older persons, reducing the risk of tooth loss and improving quality of life. It will also serve as a guide for dental surgeon in-office decision-making regarding the method to use to prevent and limit root caries lesions in older adults at risk.
Human immunodeficiency virus (HIV) infection is characterized by persistent immune activation and a constant turnover of T cells. This leads to a precipitous fall in the number of T cells, as well as to an early immunosenescence. This results in increased susceptibility to opportunistic infections. In these patients, modulation of the immune response represents a promising mechanism to maintain immunological homeostasis and prevent the development of pathology. We hypothesize that the addition of pyridostigmine to the regular combined antiretroviral therapy will result in a decrease in T cell overactivation and a reduction in circulating inflammatory markers.
Clinical trial, multicenter, double-blind, placebo-controlled, comparative of three parallel groups, randomized treatment to assess the efficacy and safety using a fixed dose combination of metformin hydrochloride with fluoxetine as adjunctive treatment in patient with obesity or overweight in order to generate new knowledge and give a greater number of therapeutic options to the clinicians, one group will receive metformin 1700 mg and 40 mg of fluoxetine; Another group will receive metformin 1000 mg with 40 mg of fluoxetine, and a third group called control will receive placebo. The above described treatments will be administered according to the "Dosage Schedule" The three groups will receive tablets of physical characteristics equal to the reference drug to preserve the blinding.
Worldwide, the incidence of preeclampsia ranges from 2 to 10% of pregnancies. The World Health Organization (WHO) estimates that the incidence of preeclampsia is seven times higher in developing countries than in developed (2.8% and 0.4%). In Mexico it is estimated that preeclampsia - eclampsia is a major cause of maternal and perinatal morbidity and mortality. Because it is an idiopathic heterogeneous syndrome associated with endothelial damage, so far there is no effective treatment to decrease the morbidity and mortality of this entity, so it is necessary to strengthen prevention; the use of aspirin alone is inconclusive, in addition to the information the investigators have reduced the effect of these strategies on arterial stiffness; Moreover, it has been observed that L-arginine lowers blood pressure in this population. It is for this that is of interest to know the efficacy and safety of the combination of L-arginine low dose, which is known as an important eNOS in NO production substrate, and aspirin for its qualities of antiinflammatory and anticoagulant in the prevention of preeclampsia and also determine their effect on arterial stiffness as a noninvasive method, as is the applanation tonometry.
Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder in reproductive age women. PCOS is usually characterized by an excessive androgen production, menstrual irregularities, and polycystic ovaries. Women with PCOS are often obese and have a varying degree of insulin resistance (IR). Weight reduction constitutes the initial treatment for these patients. Metformin has proven to be useful in IR and is frequently used in PCOS. However metformin use may be accompanied by gastrointestinal discomfort, and a high abandon rate. Other therapeutic alternatives such as magnesium and polyunsaturated fatty acids have been used in other IR states and may be useful in PCOS. The aim of this study is to asses the efficacy of these alternatives in obese PCOS patients.
