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.
RATIONALE: Studying quality-of-life in patients undergoing cancer treatment may help identify the intermediate and long-term effects of treatment on patients with cancer. PURPOSE: This clinical trial is studying quality of life in patients who are receiving either vinorelbine, gemcitabine, and docetaxel or paclitaxel and carboplatin for advanced non-small cell lung cancer.
A randomized controlled study is conducted on patients with histological stage III colorectal cancer assigned to postoperative adjuvant therapy of uracil-tegafur plus leucovorin (UFT+LV), UFT+LV / UFT, or UFT+LV+PSK / UFT+PSK. The usefulness of the three regimens was evaluated by comparing the disease-free survival rate, overall survival rate, incidence and severity of adverse event, and quality of life.
To assess the usefulness of irinotecan plus S-1 therapy based on the antitumor effect and survival period. by performing a phase II study of this combination in patients with inoperable or with postoperative colorectal cancer.
Several clinical studies in Western countries have revealed that the prevalence of HIT is 0.5 to 5%, varying depending on the clinical setting. Thirty to 50% of HIT patients suffer from thromboembolic events, and the mortality of HIT is 10 to 20%. In contrast, many physicians in Japan report no experience in treating HIT, although approximately 200,000 patients per year receive heparin. This raises the possibility that the prevalence of HIT might be much lower in Japan than in Western countries. In fact, neither the drug for HIT treatment nor the laboratory test for HIT diagnosis has been approved by the Pharmaceutical Affairs Law in Japan. We have therefore conducted a multi-center, prospective cohort study to determine the prevalence and profile of HIT in patients undergoing cardiovascular surgery or percutaneous coronary intervention. Approximately 1,500 patients will be enrolled in this study.
The aim of this trial is to study the effects of antihypertensive therapy based on home systolic blood pressure (BP) with different target levels using two classes of drugs. The HOSP study is a multicenter, prospective, randomized, open, blinded endpoint study. The study subjects are 40-79 years old hypertensive patients. After a 4 weeks of baseline period, subjects are randomly assigned to (1) modest control group (morning home BP <140 mmHg) or (2) strict control group (morning home BP <130 mmHg), and to (a) amlodipine group or (b) losartan group. Additional antihypertensive drugs can be used if home BP is not controlled. Home BP is measured in the early morning and late evening. The participants will be followed up for 5 years.
The purpose of this study is exploiting the new drugs for androgenetic alopecia because there are still no effective and safe topical drug for androgenetic alopecia. Roxithomycin is one of the macrolide antibiotics that has immunomodulatory effects. We firstly found that roxithromycin increases the rate of murine and human hair follicle elongation in vitro. Therefore, we apply this drug on this disease therapy.
The antihypertensive effect of the increased dose of angiotensin II receptor blocker (AII antagonist) is compared with that of the additional combined use of amlodipine in hypertensive patients with Type 2 diabetes mellitus, who have been treated with AII antagonist, the antihypertensive effect of which has been inadequate.
RATIONALE: Drugs used in chemotherapy, such as S-1 and irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving chemotherapy before surgery may shrink the tumor so that it can be completely removed. PURPOSE: This phase II trial is studying how well giving S-1 together with irinotecan works in treating patients who are undergoing surgery for locally advanced stomach cancer.
The JIKEI HEART Study has been designed to investigate whether concomitant treatment with valsartan, an angiotensin II receptor blocker (ARB), in addition to conventional treatment, will improve the prognosis of 3000 Japanese patients with cardiovascular diseases.
The purpose of this study is to compare an angiotensin II receptor antagonist (candesartan cilexetil– Blopress®) and a calcium channel blocker (amlodipine besilate– Norvasc®/Amlodin®) in terms of the incidence of cardiovascular events among high-risk hypertensive patients.
