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.
The purpose of the study is to identify the bacterial aetiology of acute otitis media episodes in young children aged ≥ 3 months to < 5 years in Saudi Arabia.
Primary Objective: To evaluate the efficacy of an intensive insulin regimen with insulin glargine and insulin glulisine in terms of change in Hemoglobin A1c (HbA1c) level from week 12 (visit 7) to week 24 (visit 10). Secondary Objectives: 1. Percentage of patients with HbA1c < 7% at week 24. 2. Percentage of patients with HbA1c < 7% and no symptomatic nocturnal hypoglycemia event at week 24. 3. Fasting Plasma Glucose (FPG) and 7-point Self Monitoring of Blood Glucose (SMBG) at week 0, week 12 and week 24. 4. Doses of insulin glargine and insulin glulisine: the daily dose (U) and the daily dose / kg (U/kg) will be calculated at week 24. 5. Systolic and diastolic blood pressure, heart rate, weight change will be measured at week 0, week 12 and week 24. 6. Number of patients suffering hypoglycemias (asymptomatic, symptomatic, nocturnal symptomatic, severe and nocturnal severe) will be evaluated during the treatment period. 7-Adverse events.
The investigators hypothesize that the lung resection would be associated with lower jugular bulb oxygen saturation in patients with severe pulmonary dysfunction than in patients with healthy lung functions.
The investigators postulated that the use of hyperventilation after induction of anesthesia before CO2 insufflation for laparoscopic surgery in Trendelenburg position would maintain normocapnia and reduce the hemodynamic percussion response of CO2 insufflation.
This clinical trial was conducted to study hypophosphatasia (HPP), a bone disorder caused by gene mutations or changes. These gene mutations cause low levels of an enzyme needed to harden bone. The purpose of this study was to test the safety and efficacy of a study drug called asfotase alfa (human recombinant tissue non-specific alkaline phosphate fusion protein) to see what effects it has on patients 5 years of age or less with HPP.
GISTs are the most common mesenchymal tumors of the gastrointestinal tract. Approximately 95% of GISTs are positive for KIT (CD117)-the receptor for stem cell factor (SCF). GISTs are not responsive to conventional cytotoxic chemotherapy and disease often recurs even after complete resection with wide margins. Imatinib mesylate (trade names: Glivec® and Gleevec®, imatinib, formerly STI571) is a signal transduction inhibitor targeting several protein-tyrosine kinases that are believed to play a role in the proliferation of tumor cells. In the Phase II study of imatinib [CSTI571B 2222] in 147 patients with recurrent or metastatic GIST, the partial response rates were 67% and 66% in patients treated at 400 mg/d and 600 mg/d, respectively. Skin rash and elevated transaminases were the most common reason for drug discontinuation. The most frequently reported AEs were mild nausea, vomiting, diarrhea, superficial edema (primarily periorbital or lower limb), myalgia and muscle cramps. Grade 3/4 events included fluid retention (pleural or pericardial effusions, ascites, and pulmonary edema), skin rash, liver toxicity and gastrointestinal (GI) hemorrhage. Myelosuppression (neutropenia and thrombocytopenia) was a consistent finding. Also, a tumor lysis-like syndrome occurred in some patients leading to gastrointestinal (GI) and/or intratumoral hemorrhage. In a Phase 3, American College of Surgeons Oncology Group trial (ACOSOG Z9001) of adjuvant imatinib, imatinib significantly improved 1-year recurrence-free survival (RFS) compared with placebo. In summary, clinical trials have shown that imatinib produces clinical benefit in most patients with unresectable or metastatic GIST and extends median survival from 19 to 57 months. Imatinib is the standard of care for advanced GIST and has received regulatory approval for the treatment of unresectable or metastatic GIST. Studies suggest that adjuvant imatinib for 1 year prolongs RFS in patients at high risk of recurrent disease and metastases following complete surgical resection of the primary GIST. Imatinib is an appealing adjuvant therapy for resected GIST because: 1. Patients with primary GIST have a high chance of tumor recurrence 2. Conventional adjuvant treatment modalities are ineffective 3. Imatinib specifically inhibits the Kit receptor which is constitutively activated in most GISTs 4. Imatinib inhibits the growth of Kit positive cells in vitro 5. Imatinib is highly effective in many patients with advanced GIST in a Phase II trial 6. Imatinib has been associated with minimal toxicity in patients with advanced GIST and in patients with chronic myelogenous leukemia (CML) 7. Imatinib may have its greatest impact on survival when there is minimal disease. Primary - To assess Recurrence Free Survival Rate in patients with resected primary GIST who are treated with adjuvant imatinib for a duration of 2 years Secondary - To compare Recurrence Free Survival, Overall Survival, and Time to Recurrence of patients with resected primary GIST who are treated with adjuvant imatinib for a duration of 2 years with historical data To assess the safety of imatinib given as adjuvant therapy for 2 years in patients with resected primary GIST
Vitamin D deficiency is common world wide. 25 OH vitamin D level is the best indicator of vitamin D status. Vitamin D supplements are available as vitamin D2 or D3, in small daily or large weekly/monthly doses. Controversy continues on the relative potency of vitamin D2 compared to D3 and of daily compared to weekly or monthly doses, in increasing/maintaining total 25 OH vitamin D level. The investigators plan to conduct a controlled trial to compare the effect of various vitamin D supplements on 25 OH vitamin D levels in healthy adults with starting 25 OH vitamin D level between 20 to 50 nmol/L.
Systemic Pulse Glucocorticoids have been shown to be effective in widespread Alopecia areata but not the totalis, universalis or ophiasic type. Whether the failure is due to inadequate dosing, inadequate frequency or other factors is a matter of debate. The investigators decided to conduct this study using the oral pulse steroid, however with higher doses and more frequent pulses to patients with severe forms of Alopecia areata.
It will be conducted as an international multicenter prospective observational cohort study in a population of ErbB2 positive metastatic breast cancer patients, whose disease has progressed after trastuzumab-containing regimen, comparing outcomes in two groups: Group 1: patients receiving Lapatinib-capecitabine immediately after 1st Trastuzumab progression (second line treatment), and Group 2: patients receiving Lapatinib-capecitabine after 2 or more lines of treatment after 1st trastuzumab progression (third line or greater).
