The Overgrowth Study

Currently Recruiting

25 May 2026

Up to $4,970

Melbourne, Australia

Overgrowth conditions are rare disorders where certain parts of the body grow more than they should. This happens because of a change in a gene called PIK3CA, which normally helps control how cells grow. In these conditions, the gene sends too many growth signals, causing extra tissue or abnormal blood vessels to form in specific areas, such as an arm, leg, or part of the body. The change isn’t inherited and only affects some cells, which is why the overgrowth is uneven rather than affecting the whole body. Over time, this extra growth can lead to pain, swelling, movement difficulties, or circulation issues, and may gradually worsen if left untreated. We are looking at a potential new oral treatment for these conditions, due to the limitations in current treatment.
