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.
The purpose of this randomized withdrawal study is to evaluate the safety, tolerability, and efficacy of memantine compared with placebo in pediatric patients with autism, Asperger's Disorder, or Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS).
This study is a randomized clinical trial designed to compare the susceptibility of naive and pre-immune volunteers to infectious challenge with viable Plasmodium vivax sporozoites. The term preimmune hereafter denoted only previous experience with infection by this parasite and not a definite state of immunity to malaria infection. The study hypothesis is that pre-immune volunteers present a delayed onset of malaria clinical and parasitological manifestations when compared to naive individuals. The development of this study will establish a protocol for evaluating the effectiveness of vaccine candidates against P. vivax in subsequent Phases IIa and IIb clinical trials.
Haemophilia A is an inherited disorder in which one of the proteins, Factor VIII, needed to form blood clots is missing or not present in sufficient levels. In a person with haemophilia A, the clotting process is slowed and the person experiences bleeds that can result in serious problems and potential disability. The current standard treatment for severe haemophilia A is regularly scheduled infusion of FVIII to keep levels high enough to prevent bleeding. Due to the short half-life of FVIII, prophylaxis may require treatment as often as every other day. In this trial safety and efficacy of a long-acting recombinant factor VIII molecule is evaluated in subjects with severe Hemophilia A. 120-140 patients will receive open label treatment with long-acting rFVIII either on-demand to treat bleeds or prophylactically for 36 weeks in the main trial plus an optional extension to continue treatment for at least 100 total exposure days (ED). Patients on prophylactic treatment will receive study drug at dosing intervals between once and twice a week depending on their observed bleeding. Patients will attend the treatment centre for routine blood samples and be required to keep an electronic diary. Male patients aged 12-65, with severe hemophilia A, previously treated with FVIII for at least 50 exposure days may be eligible for this study.
To compare the maintenance of efficacy of the combination of etanercept 50 mg once weekly plus methotrexate with or without other disease modifying antirheumatic drugs therapy with that of methotrexate with or without other disease modifying antirheumatic drugs therapy at Week 52 in subjects with moderately to severely active rheumatoid arthritis who have achieved low disease activity after 24 weeks of therapy with open label etanercept 50 mg once weekly plus MTX with or without other disease modifying antirheumatic drugs therapy.
The purpose of this study is to determine the effect of three times a day mastication, during a follow-up period of 4 weeks, of two sugar-substituted chewing gums on various factors associated with dental caries and gingivitis.
RATIONAL is a multinational, multicentre, observational, cross sectional study of adult patients in treatment with NSAID therapy for OA, RA or AS during for at least 2 weeks before study visit (at least one dose).
This is a 2-year study to evaluate the effect of denosumab versus risedronate in adults with glucocorticoid-induced osteoporosis.
The purpose of this study is to determine if treatment with romosozumab is effective in preventing fractures in women with postmenopausal osteoporosis
This multicenter, two-cohort, non-randomized, open-label study will evaluate the safety and tolerability of assisted and self-administered SC Herceptin as adjuvant therapy in participants with early HER2-positive breast cancer following tumor excision. Participants will receive Herceptin 600 milligrams (mg) SC every 3 weeks for 18 cycles, either by an assisted administration using a conventional syringe and needle/vial formulation (Cohort A) or with assisted and self-administration using a single-use injection device (SID) in selected participants (Cohort B).
This multicenter, prospective, observational study will assess the efficacy of MabThera/Rituxan (rituximab) and alternative TNF-inhibitors in patients with rheumatoid arthritis who are non-responders or intolerant to a single previous TNF-inhibitor. Data will be collected from each patient from the time of change in biologic therapy for 12 months.
