Long-term safety registry for Increlex in children
This study is a registry that follows children and teens with severe IGF-1 deficiency who use Increlex (or specific GH gene deletion situations) to better track long-term safety and effectiveness. You would likely join if your child is already starting or planning Increlex and is not in other growth-related drug trials.
Orange, CaliforniaAges 2–18 - NCT00981396RecruitingEarly Phase 1

Testing ablation treatment for Barrett’s with precancer changes
This trial studies whether an “ablation” procedure (destroying abnormal esophagus lining) works well for people with Barrett’s esophagus that has high-grade precancer changes or very early cancer. It may help find safer or more effective ways to prevent the condition from worsening.
Rochester, MinnesotaAges 18–90 - NCT01134770Enrolling by invitation
