There are about 1320 clinical studies being (or have been) conducted in Saudi Arabia. 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.
This phase II trial studies how well reduced doses of radiation therapy to the brain and spine (craniospinal) and chemotherapy work in treating patients with newly diagnosed type of brain tumor called WNT)/Wingless (WNT)-driven medulloblastoma. Recent studies using chemotherapy and radiation therapy have been shown to be effective in treating patients with WNT-driven medulloblastoma. However, there is a concern about the late side effects of treatment, such as learning difficulties, lower amounts of hormones, or other problems in performing daily activities. Radiotherapy uses high-energy radiation from x-rays to kill cancer cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, vincristine sulfate, cyclophosphamide and lomustine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving reduced craniospinal radiation therapy and chemotherapy may kill tumor cells and may also reduce the late side effects of treatment.
The purpose of this study is to estimate the proportion of participants fulfilling criteria for symptomatic remission following a transition to 12 months treatment with flexible-dose paliperidone palmitate 3 month formulation (PP3M) in participants with schizophrenia previously adequately treated with paliperidone palmitate 1 month formulation (PP1M) for at least 4 months.
The purpose of this study is to evaluate the efficacy of probiotic products on caries-associated salivary bacterial counts (Streptococcus mutans and Lactobacillus) and its effect on dental plaque accumulation in a group of preschool children in Saudi Arabia.
This study consists of two parts (Part 1 and Part 2). The purpose of Part 1 is to evaluate the way the body absorbs, distributes, metabolizes and removes the drug LCZ696. This will help determine the proper dose of LCZ696 for Part 2 of the study. The purpose for Part 2 is to compare the effectiveness and safety of LCZ696 with enalapril in a double-blind manner, in pediatric heart failure patients over 52 weeks of treatment.
A prospective randomized parallel trial will be carried out on 100 patients who have extraction of single molar tooth. Teeth extractions will be done under local anesthesia. The patients will be divided randomly into two parallel groups. Group 1: The patients will start using Chlorhexidine mouthwash on the second day of extraction twice daily for 7 days. Group 2: After extraction, Manuka Honey will be applied topically into the extraction socket. Postoperative instructions will be given for all patients in addition to the prescription of ibuprofen 600 mg every 8 hours for 3 days. Re-evaluation: Postoperative day 3: tenderness with probing the socket, empty socket, food debris, halitosis and assessment of pain. For group 2, the intra-alveolar application of honey will be repeated. Re-evaluation will be repeated in the seventh post-operative day. Acute alveolar osteitis, (dry socket) is diagnosed if the patient presented between the 2nd and 4th days with pain or tenderness in the socket with probing, empty socket and food debris with or without halitosis.
Children in their seventh year of life (age range of 6 to 7 years) will be included in the study. All children included in the study would have to classified according to the Wright behavior classification as potentially co-operative and rated as per the Frankl behavior rating scale as positive (++) Group A and negative (-) Group B . All children included must have had no prior experience of dental anesthesia and must have at least one tooth requiring restorative procedure on either side of the maxillary arch. Intervention Description 1. Regular Anesthesia All the subjects received local anesthesia injection in maxillary arch as is commonly practiced in dental clinics. Information obtained before assignment of intervention or standard care included age, gender, type of injection given alongside the vibration device will be recorded beforehand. During the delivery of anesthesia for all the groups, anticipated and actual pain will be recorded to show the impact of anxiety on the experience of participants. During the entire process, all participants will use standard needles with confirmed specification to control for any potential confounders 2. Buzzy® The use of the external cold and a vibrating Device will follow the manufacturer's recommendations to ensure that normal clinical scenario is created.
Autologous Fat Derived Stem Cell treatment of ED. To assess safety and primary efficacy of stem cell infusion in refractory ED. To investigate the success rate and durability of success of using this new therapy in management of moderate and sever cases of erectile dysfunction.
Depression is a serious mental health disease. It is generally characterized by sadness, loss of interest in activities, and decreased energy. Globally, it is estimated that almost 350 million people suffer from depression. In Saudi Arabia, literature suggested that prevalence of depression among boy's secondary school students in Abha city was 38.2%. Another study found that the prevalence of depression was 22.4 % as moderate, 7.3 % as severe and 3.7% as very severe, with a clear predominance prevalence of depression in girls as in boys (1.5 times). It is important to assess depression literacy including knowledge and beliefs about mental disorders among adolescent. A high level of mental health literacy on depression leads to a better understanding and outcomes of depressive disorders. Schools are a typical venue in which to embed mental health literacy because the school students are more familiar with educational activities. Studies concluded that educational intervention about depression literacy and destigmatization improves knowledge and may decrease stigma. Further research, intervention and activism are needed in the field of mental health in Arab countries to improve awareness of mental health problems. Objectives: This study is aimed to measure the effect of educational intervention program about depression among secondary schools in Jazan city on depression literacy and stigma during the academic year 2015-2016. The intervention: the intervention will held at each selected intervention school separately. The program will be over 2 weeks intervention as the following: - Educational strategies: 2 Lecture about depression 30 minutes supported by group discussion, brochures and display of posters with mental-health slogans on depression in the schools. - Contact strategies: the investigators will show a video of a young male who had been diagnosed (i.e., not an actor) with depression. Benefits: * The intervention group will join educational intervention program they expected to benefit from the program through increase their depression literacy and improve depression stigma, and control group will not join any form of intervention. Risk: There is no expected risk for participating in the study. Consent: Three Informed Consents forms will be signed from students, guardians and school manager.
To explore two modalities of treatment initiation (Pre-discharge, and Post-discharge) with LCZ696 in HFrEF patients following stabilization after an ADHF episode.
The purpose of this study was to evaluate the long term efficacy and safety of intravitreal ranibizumab compared with laser ablation therapy in patients who were treated for retinopathy of prematurity (ROP) in the core study CRFB002H2301 (NCT02375971)
