There are about 1933 clinical studies being (or have been) conducted in Colombia. 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.
Using gene therapy to express active telomerase (hTERT) in human cells has the potential to treat many diseases related to aging, including critical limb ischemia (CLI). This study will entail treating subjects with hTERT delivered via transduction using AAV. The goal is to extend the telomeres to prevent, delay, or even reverse the development of the pathology of CLI. It is expected to have a direct consequence on function and quality of life in patients with Peripheral artery disease (PAD); in this case a subgroup of patients with CLI, the worst presentation of PAD.
Cross-sectional epidemiological study in patients with diagnosis of osteoarthritis (OA) in order to evaluate risk factors associated with the use / prescription of non-steroidal anti-inflammatory drugs (NSAID).
Epidemiological study (cross-sectional study) in order to determine the patients who present an adequate control of the Blood Pressure (BP), in a population of Colombian patients diagnosed with Arterial Hypertension (AH) and who are under pharmacological treatment.
Cross-sectional epidemiological study in patients with diagnosis of GERD (Gastroesophageal Reflux Disease) and with current treatment or with a history of recent treatment with some PPI (Proton Pump Inhibitor), in order to evaluate the persistence and / or relapse of symptoms of GERD.
OBJECTIVE: To evaluate the effects of different time intervals activations on the non-surgical maxillary expansion in adults. Methods: This study will include two groups, 10 adult patients each (mean age 20-35) with maxillary transverse deficiency and unilateral or bilateral crossbite. In the first group, the expansion is going to be activated every four days. In the second group, activation will occur every eight days. The primary outcomes are transverse dimension, the buccal cortical bone formation, and the upper premolar and molar labial inclination. Dentoalveolar changes will be evaluated using CBCT images and digital models.
This study will evaluate the efficacy and safety of ocrelizumab ( Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study focuses on upper limit disability progression. This study will consist of the following phases: screening, double-blind treatment, follow-up 1 (FU1), an optional open-label extension (OLE), follow-up 2 (FU2), and B-cell monitoring (BCM).
The study is aimed to determine the potential of volatile marker testing for gastric cancer screening. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.
Prospective data will be collected in approximately 200 patients treated with an TMJ replacement. Patients will be followed up according to the standard (routine) for up to 5 years after the treatment. Data collection will include underlying disease, treatment details, functional and patient reported outcomes (PRO)s and anticipated or procedure-related adverse events (i.e. complications). This registry is designed to be able to assess the number of patients who refuse alloplastic total TMJ replacement. Therefore, the participating sites are asked to register all cases of refused TMJ replacements too.
The investigators' main objective is to determine the prevalence of pre-treatment of resistance-associated mutations (RAMs) in a naïve and recently diagnosed HIV infection in 18 centers from 12 cities in Colombia. This evaluation will include the genotyping of all three enzymes, reverse transcriptase, protease, and integrase. This type of complete primary resistance profile has not yet been reported in Colombia and there is only scanty data regarding resistance-associated mutations to NRTIs, NNRTIs, and PIs in the country
To evaluate the efficacy of romiplostim for the treatment of CIT in patients receiving chemotherapy for the treatment of NSCLC, ovarian cancer, or breast cancer measured by the ability to administer on-time, full-dose chemotherapy
