Lympocytic, Follicular clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Study of Lymphoma in Asia

Start date: July 5, 2011
Phase:
Study type: Observational

Background: - Lymphoma rates in Asia have been lower than in the West, but rates have been rising in recent years. Most studies of lymphoma patients have been conducted in the West. Less information is available about the factors that might contribute to the rise of lymphoma in Asia. Researchers want to collect medical and personal histories and samples from people who have recently been diagnosed with lymphoma. This information will help them study possible reasons for this increase. Objectives: - To collect samples and histories as part of an introductory study of lymphoma in Asia. Eligibility: - People between 18 and 79 years of age who have entered study hospitals in Hong Kong, Taiwan, and mainland China for treatment for any type of lymphoma. - Healthy volunteers between 18 and 79 who have never had lymphoma. Design: - Participants will be screened with a physical exam and medical history. - They will provide blood samples and cheek cell samples for testing. - Participants will complete a questionnaire about their personal health history. They will answer questions about exposures to chemicals like pesticides. They will also be asked about family medical history and work and residential history. Finally they will answer questions about lifestyle factors like diet and exercise. - They will give permission for the researchers to see their medical records. Researchers will also have access to any tumor samples collected as part of treatment.
