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 compare two ways of using anti-HIV drugs to help health care providers and patients decide how to best use anti-HIV treatments over many years. Many health care providers now treat patients with daily drugs to keep the viral load as low as possible. This approach helps patients with CD4 counts less than 200-250 cells/mm3 live longer without serious diseases. But it is not known if this is the best way to treat patients with higher CD4 counts. There is information suggesting that these patients may be able to wait to use anti-HIV drugs while CD4 counts are above 250 cells/mm3. Because this study will be carried out over several years, it will provide information on the long-term advantages and disadvantages of these two treatment strategies.
This phase II trial studies the effectiveness of paclitaxel in treating patients who have ovarian stromal cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells and prevent the spread of cancer to the brain. It is not yet known if standard-dose radiation therapy is more effective than high-dose radiation therapy in preventing the spread of limited-stage small cell lung cancer cells to the brain. PURPOSE: This randomized phase III trial is comparing two different regimens of radiation therapy to see how well they work in treating patients with limited-stage small cell lung cancer in complete remission.
The purpose of this study is to see if it is effective to give HIV positive patients recombinant interleukin-2 (rIL-2) in addition to anti-HIV therapy. Patients will be followed over a minimum of 4 years to study the long-term effects of rIL-2 on their HIV disease progression. Anti-HIV therapy has been very successful in treating HIV positive patients and in keeping viral load (level of HIV in the blood) low. However, anti-HIV drugs cannot completely rid the body of the virus, and the immune system is never completely restored in HIV positive patients. Doctors hope that giving patients recombinant interleukin-2 (rIL-2) in addition to their anti-HIV therapy will help improve their immune systems and keep them healthier over a longer period of time. rIL-2 is a hormone naturally produced by the body during an immune response to a microbial infection.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether receiving combined carboplatin and paclitaxel plus continued low-dose paclitaxel is more effective than carboplatin and paclitaxel alone for early-stage ovarian cancer. PURPOSE: This randomized phase III trial is studying carboplatin and paclitaxel alone too see how well they work compared to carboplatin and paclitaxel together with continued low-dose paclitaxel in treating patients with early-stage ovarian cancer.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if combination chemotherapy given after surgery is more effective than surgery alone for non-small cell lung cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy following surgery with that of surgery alone in treating patients who have stage I, stage II, or stage IIIA non-small cell lung cancer.
Stuttering is an abnormality in speech that affects the rhythm of speech. People who stutter know what they wish to say, but at the time are unable to say it because of involuntary repetition, unnecessary lengthening (prolongation), or early stopping (cessation). Stuttering is characterized by repetitions or prolongation of the first syllable, or silent prolongations, sometimes known as blocks. Researcher intend on studying the genetic basis for stuttering. The goal of the study is to find the genes that help cause stuttering and determine regions of the human genetic make-up (genome) that are linked to stuttering.. To do this researchers will study the patterns of inheritance in families who have had members who stutter. The study has two objectives. The first objective is to develop a large collection of DNA samples from individuals in stuttering families, that will include both members that stutter and who do not stutter. The second objective of the study will be to find out the basic combination of genes (genotype) making up all of the participants DNA. Once this is completed researchers hope to map out and find areas or regions of DNA that are linked to stuttering. Genetic linkage is the initial step in positional cloning, and the cloning of genes which predispose individuals to stuttering is a long term goal of this research study.<TAB>
