There are about 7997 clinical studies being (or have been) conducted in Japan. 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 study is to evaluate safety and effectiveness of golimumab in Japanese participants with moderately to severely active ulcerative colitis.
The purpose of this study is to collect and assess long-term safety of nilotinib in patients who are on nilotinib treatment in a Novartis-sponsored, Oncology CD&MA study and are benefiting from the treatment as judged by the investigator.
The primary objective of this trial is to demonstrate the non-inferiority of the clinical pregnancy rate per embryo transfer to the historical standard value in in-vitro fertilization (IVF)/embryo transfer (ET) cycles in Japan (Japan Society of Obstetrics and Gynecology [JSOG] 2009 registry data: 24.3 percent [%]). The secondary objectives of this trial are to assess the biochemical pregnancy rate per ET, pharmacokinetics, and safety of COL-1620.
Clinical features, optical coherence tomography findings and surgical outcome in eyes with macular retinoschisis and detachment with normal tension glaucoma but without optic disc pit or high myopia were evaluated.
Elderly patients have poorer preoperative conditions than younger patients. Therefore, minimally invasive surgery should be an effective treatment method for elderly patients. The investigators conducted a randomized trial that compared laparoscopic surgery and conventional open surgery in elderly patients who were 75 years old or over. The purpose of the present study was to clarify the effect of laparoscopic surgery in elderly patients. In our hypothesis of this trial, laparoscopic surgery is superior to conventional open surgery in short-term results, and same outcome in long -term results. Therefore, laparoscopic surgery would be recommended as standard procedure in an elderly colorectal patient.
To investigate the prognosis due to presence or absence of bile duct resection in intrahepatic cholangiocarcinoma that require hepatic lobectomy.
The long-term results of several large-scale prospective randomized trials that compared laparoscopic-assisted and open colectomy for colon cancer were published in the past decade. The oncologic outcomes were nearly similar in patients who underwent laparoscopic or open surgery. In Japan, the Japan Clinical Oncology Group (JCOG) conducted a randomized trial to compare oncological outcomes between patients who underwent laparoscopic or open surgery for advanced colon cancer and recto-sigmoid cancer. However, the exclusion criterion were concerning tumor site in transverse and descending colon. The reason of exclusion was that laparoscopic procedure was difficult in transverse and descending colon cancers. However, laparoscopic surgery for transverse and descending colon cancer was performed clinically. We conducted a randomized trial that compared laparoscopic surgery and conventional open surgery in in transverse and descending colon cancer. The purpose of the present study was to clarify the safety and feasibility of laparoscopic surgery on in transverse and descending colon cancer patients.
The tying at a radix of the inferior mesenteric artery (IMA) is recognized as radical cure technique in a rectal cancer surgery in Japan. In one side, the preserving the left colic artery (LCA) that is the technique to maintain blood flow of proximal sigmoid colon is performed in practice. However, there is no evidence that shows effectiveness of this technique. We conducted a randomized trial that compared between high tie and low tie of the IMA in rectal anterior resection to define an appropriate portion of IMA tying.
The objectives of this study are: to confirm the superiority of TAU-284 over placebo after two weeks of administration to pediatric patients with perennial allergic rhinitis and to investigate safety of TAU-284.
To investigate the vessel resection and reconstruction in biliary tract cancer.
