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 randomized phase II/III trial studies how well standard of care therapy with stereotactic radiosurgery and/or surgery works and compares it to standard of care therapy alone in treating patients with breast cancer that has spread to one or two locations in the body (limited metastatic) that are previously untreated. Standard of care therapy comprising chemotherapy, hormonal therapy, biological therapy, and others may help stop the spread of tumor cells. Radiation therapy and/or surgery is usually only given with standard of care therapy to relieve pain; however, in patients with limited metastatic breast cancer, stereotactic radiosurgery, also known as stereotactic body radiation therapy, may be able to send x-rays directly to the tumor and cause less damage to normal tissue and surgery may be able to effectively remove the metastatic tumor cells. It is not yet known whether standard of care therapy is more effective with stereotactic radiosurgery and/or surgery in treating limited metastatic breast cancer.
This phase III trial studies tretinoin and arsenic trioxide in treating patients with newly diagnosed acute promyelocytic leukemia. Standard treatment for acute promyelocytic leukemia involves high doses of a common class of chemotherapy drugs called anthracyclines, which are known to cause long-term side effects, especially to the heart. Tretinoin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Arsenic trioxide may stop the growth of cancer cells by either killing the cells, by stopping them from dividing, or by stopping them from spreading. Completely removing or reducing the amount of anthracycline chemotherapy and giving tretinoin together with arsenic trioxide may be an effective treatment for acute promyelocytic leukemia and may reduce some of the long-term side effects.
The purpose of Phase 1b of this study is to: - Asses the safety, tolerability and activity of carfilzomib, alone and in combination with induction chemotherapy, in children with relapsed or refractory acute lymphoblastic leukemia (ALL). - Determine the maximum tolerated dose (MTD) and to recommend a phase 2 dose of carfilzomib in combination with induction chemotherapy. The purpose of Phase 2 of this study is to compare the rate of complete remission (CR) of carfilzomib in combination with vincristine, dexamethasone, PEG asparaginase, daunorubicin (VXLD) at the end of induction therapy to an appropriate external control.
During LA in retinal surgery there is some problem as regard the lack of anaesthesia duration and unexpected globe movement .so many adjuvant was added to LA to overcome this disadvantages of LA such as clonidine and fentanyl . The investigators hypothesis is adding dexmedetomidine to pribulbal blocking LA will prolong anaesthesia duration and improve globe akinesia and decrease intraoperative supplementation of LA.There are Many studies had described the effects of dexmedetomidine on peripheral nerve blocks, spinal but up to date no knowledge is available on the impact of dexmedetomidine adjuvant to local anaesthetic in ophthalmic surgery
This randomized phase II trial studies the side effects and how well modestly reduced-dose intensity-modulated radiation therapy (IMRT) with or without cisplatin works in treating patients with oropharyngeal cancer that has spread to other places in the body (advanced). Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, 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. It is not yet known whether IMRT is more effective with or without cisplatin in treating patients with oropharyngeal cancer.
The e-Ultimaster will further validate the safety and efficacy of Ultimaster DES system in unselected patients representing everyday clinical practice. Also the study will assess the impact of non-compliance with dual antiplatelet therapy, one month after stent implementation (frequently observed in every day clinical practice), on stent thrombosis.
This phase III trial studies how well response and biology-based risk factor-guided therapy works in treating younger patients with non-high risk neuroblastoma. Sometimes a tumor may not need treatment until it progresses. In this case, observation may be sufficient. Measuring biomarkers in tumor cells may help plan when effective treatment is necessary and what the best treatment is. Response and biology-based risk factor-guided therapy may be effective in treating patients with non-high risk neuroblastoma and may help to avoid some of the risks and side effects related to standard treatment.
The purpose of the Evera MRI™ study is to confirm safety and efficacy of the Evera MRI ICD (Implantable cardioverter-defibrillator) System in the clinical MRI (Magnetic Resonance Imaging) environment when subjects receive MRI scans without positioning restrictions (MRI scans may occur anywhere on the body).
Narrowing of coronary arteries interferes with blood flow and can cause chest pain. But patients may have more than one narrowing and studies have shown that not all narrowings need to be treated. To identify the narrowings that need treating cardiologists sometimes quantify the extent of the narrowing by measuring fractional flow reserve (FFR, the ratio of the pressure in the aorta to the pressure downstream of the narrowing).This technique requires the administration of drugs that add cost and time to the procedure and in some countries are simply unavailable. As a result despite the clear health and healthcare costs benefits of FFR its use is limited to less than 5% of procedure. We have developed a new technique called the instantaneous wave-free ratio (iFR) that does not require the administration of drugs for its accurate assessment. It has been approved for use in this indication. This study aims to compare clinical outcomes of patients whose treatment has been guided by iFR to those whose treatment has been guided by FFR. If iFR is found to provide the same clinical outcomes as FFR its adoption will permit the clear benefits of this approach of identifying the coronary narrowings that really need treatment to be applicable to a much larger patient population and further improve healthcare costs.
