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 is a Phase II/III randomized study involving non-metastatic rectal cancer patients who are candidates for neoadjuvant chemoradiotherapy. Eligible patients will be randomized between two treatment arms: Experimental arm: Long course CRT is followed by 4 cycles of combination chemotherapy of modified FOLFOX6 or 3 cycles of XELOX and then surgery. After surgery, patients with pT0-2 N0 will not receive adjuvant chemotherapy. Patients with higher pathological stage will receive adjuvant chemotherapy (4 cycles of modified FOLFOX6 or 3 cycles of XELOX). Standard arm: Long course CRT will be followed by surgery 10-12 weeks after the end of CRT. After surgery, patients with pT0-2 N0 will not receive adjuvant chemotherapy. Patients with higher pathological stage will receive adjuvant chemotherapy (8 cycles of modified FOLFOX6 or 6 cycles of XELOX). The study aims to assess the efficacy of consolidation chemotherapy given in the interval between the end of CRT and surgery to allow for early initiation of systemic therapy aiming to decrease distant relapse rate and enhancing pathological response.
The study assesses the effect of a new vibration system on pain reduction during the injection of local anesthesia. Children undergoing dental treatment are allocated to two groups; one receiving the Buzz, a vibration system and another group receiving nothing. Pain during injection of local anesthetic is assessed using a validated tool in addition to assessment of child cooperation during treatment.
A chart review study of patients with haemophilia A with inhibitors treated with rFVIIIFc (Elocta®) for immune tolerance induction.
The exact pathogenesis of PSP is controversial. A few theories has been proposed contributing to the pathogenesity of the PSP as emphysematous like changes (ELCs) which lead to the formation and rupture of the lung bullae or blebs; and increased pleural porosity which is an abnormality of the visceral pleura. The Video-Assisted Thoracoscopic Surgery with bullectomy only is an effective preventive method of PSP recurrence. Adding mechanical pleurodesis to bullectomy is still questionable in the literature. This prospective multicenter study will identify the rate of PSP recurrence after thoracoscopic bullectomy only versus thoracoscopic bullectomy with mechanical pleurodesis.
patients with metastatic colorectal cancer who were initially RAS wild and failed at least 2 lines of chemotherapy will be enrolled. Anti-EGFR must have been given in 1st line. Those who remain RAS-wild upon retesting will receive rechallenge with panitumumab and chemotherapy
Treatment with PF-06741086 is anticipated to demonstrate a clinically relevant advantage and/or a major contribution to patient care in comparison to current methods of treatment for hemophilia A or B because it works differently than factor replacement products and will work in the presence of inhibitors. The potential for once weekly (QW) subcutaneous (SC) administration provides for treatment options in the absence of reliable vascular access, increased convenience and may enable better compliance. Combined, these qualities should result in a reduction of bleeding episodes.
The aim of the HEM-POWR study is to understand better how Damoctocog alfa pegol (Jivi) is used to treat people with Hemophilia A in day-to-day life, how well the treatment is tolerated and how satisfied patients and physicians are with the treatment.
The purpose of this cross-sectional, multicenter study is to determine the prevalence of an eosinophilic phenotype of blood eosinophil count ≥ 300 cells/mm3 among severe asthma patients who attend to sites specialized in the management of severe asthma in several countries in the AstraZeneca International Region. The prevalence of an atopic phenotype and asthma control, will also be studied.
Fluoride products are proven to be cost effective in preventing dental caries. Newer Fluoride products have been released in the market with different components that may have an impact on the clinical and radiographic outcome regarding incipient caries management. The objective of the study is to compare the effectiveness of PreviDent and MI varnish to (1.23%) Acidulated phosphopeptide Fluoride (APF) on remineralisation of non-cavitated proximal incipient lesions.
Transfusions are one of the most overused treatments in modern medicine, and saving blood is one important issue all around the world. Cardiac surgery makes up a large percentage of the overall blood components consumption in surgery. Acute normovolemic hemo-dilution (ANH) is a well-known strategy which has been used for years without the support of high quality evidence based medicine to improve post-cardiopulmonary bypass coagulation and reduce red blood cells (RBC) transfusion. We designed a multicenter randomized controlled trial to investigate the effect of ANH in reducing the number of cardiac surgery patients receiving RBC transfusions during hospital stay. We will randomize 2000 patients to have sufficient power to demonstrate a 20% relative and 7% absolute risk reduction in the number of patients' RBC transfusion. If the results of the study will confirm our hypothesis, this will have a great impact on blood management in cardiac operating room.
