Sibling 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.

Long Term Minor Sibling Donor Well-Being

Start date: April 2008
Phase: N/A
Study type: Observational

The goal of this research study is to understand what it is like for a young person to have a sick family member and what it is like to donate bone marrow or stem cells for a sick family member. Primary Aims: 1. Compare minor donor adjustment to minor non-donor adjustment, including anxiety, self-esteem, traumatic stress, achievement, and behavior. 2. Evaluate minor donor adjustment across time, including self -esteem, traumatic stress, anxiety, achievement, and behavior. 3. Investigate the effect of the following on donor well-being: - Donor variables: 1) the impact of the harvest, including type of harvest (needle aspiration of bone marrow or peripheral blood stem cell collection by apheresis after injection of G-CSF), pre-procedural anxiety and perceived pain; 2) age of donor at time of transplant, 3) gender, 4) preparedness for transplant, 5) sibling order (for sibling participants), and 6) donor's decision-making and ambivalence regarding donation. - Recipient variables: 1) the recipient's level of well-being or death, 2) genetic versus acquired disease types, and 3) familial relationship of donor to recipient. - Family support variables: 1) the distress of the family, 2) the quality of the relationship between the potential donor and the recipient, and 3) parent's well-being (post-traumatic stress disorder or PTSD, depression). Secondary Aim: Evaluate satisfaction with the donor program.
