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.
Alzheimer's disease (AD) is a fatal degenerative disease of the brain for which there is no cure. AD causes brain cells to die. AD is thought to be caused by an excess of beta amyloid (β-amyloid), a sticky protein in the brain that forms amyloid plaques. At autopsy, AD patients are required to have these amyloid plaques in the brain in order to have a definitive diagnosis of AD. Inhibiting the enzyme gamma-secretase (γ-secretase) lowers the production of β-amyloid. Semagacestat (LY450139) is a functional γ-secretase inhibitor and was shown to lower β-amyloid in blood and spinal fluid in humans tested thus far and in blood, spinal fluid and brain in animals tested thus far. This study used several different tests to measure the effect of semagacestat on both β-amyloid and amyloid plaques for some patients. The buildup of amyloid plaques was measured by a brain scan that takes a picture of amyloid plaques in the brain. Other tests measured the overall function of the brain and brain size in some patients. In this trial, patients who initially received placebo (inactive sugar pill) were, at a certain point in the study, switched over to active drug, semagacestat. In other words, all patients could eventually receive active drug. Each patient's participation could last approximately 2 years. Patients taking approved AD medications were permitted to participate in this study and continue taking these medications during the study. All patients who completed this study had the option to continue receiving semagacestat by participating in an open label study. Preliminary results from this study (LFBC) (and another similar study LFAN [NCT00594568]) showed semagacestat did not slow disease progression and was associated with worsening of clinical measures of cognition and the ability to perform activities of daily living. Study drug was stopped in all studies. LFBC, LFAN and open label LFBF (NCT01035138) have been amended to continue collecting safety data, including cognitive scores, for at least seven months. The CT-Registry will reflect results of analyses from the original protocol in addition to those from the amended protocol.
The purpose of this study is to compare the effectiveness of teriparatide versus therapies that decrease bone loss to prevent new or worsening back pain in patients with osteoporosis seen in clinical practice.
In this multinational Phase III study the efficacy and safety of 10 µM AP 12009 is compared to standard chemotherapy (temozolomide or BCNU or CCNU) in adult patients with confirmed recurrent or refractory anaplastic astrocytoma (WHO grade III) or secondary glioblastoma (WHO grade IV).
This study is an international, multi-center, randomized, double-blind, placebo-controlled study in subjects with PAH who are currently receiving approved therapy for their PAH (i.e., endothelin receptor antagonist and/or phosphodiesterase-5 inhibitor)or as a monotherapy treatment. Study visits will occur at 4 week intervals for 12 weeks with the key measure of efficacy being the 6-minute walk test. Study procedures include routine blood tests, medical history, physical exams, disease evaluation, and exercise tests. At the end of the first 12-weeks, the patient will be un-blinded. Patients will continue with another 12-Week open label portion with visits occuring at 4-week intervals. Patients who complete all assessments for 24-weeks will also be eligible to enter a 36 month open-label, extension phase study (FREEDOM - EXT).
Children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) who are not tolerating or not responding well to stimulant therapy will be included in this study. Two different strategies for transition from Stimulant to Atomoxetine will be used: Slow (10 weeks) and fast (2 weeks). Changes in ADHD symptoms and tolerability of medication will be compared between the two different switching approaches.
The purpose of this study is to determine the efficacy and safety of SYR-472, once daily (QD), in subjects with type 2 diabetes mellitus who have not achieved glycemic control with diet and exercise, or by taking metformin.
The purpose of this study is to determine whether plasma levels of lipopolysaccharide binding protein (LBP) are correlated with PBMN pro- and anti-inflammatory cytokine secretion, as well as with the development of severe infectious events in cirrhotic patients with ascites. As a secondary purpose, the study will evaluate the effect of a prophylactic administration of ciprofloxacin on LBP, cytokines and infections in the same patients.
The purpose of the study is to determine the safety and efficacy of AN2728 Ointment, 5%, compared to Ointment Vehicle in the treatment of plaque type psoriasis.
The purpose of this study is to demonstrate, in 12-23 months old subjects, the non-inferiority of meningococcal vaccine GSK134612 and pneumococcal vaccine GSK1024850A when co-administered, compared to each vaccine administered individually.
The purpose of this study is to evaluate the lot-to-lot consistency of three production lots of GSK Biologicals' HRV vaccine in terms of immunogenicity and safety in healthy infants aged 2 months at the time of first vaccination.
