The first clinical trial for a CVS drug

The vast majority of drugs for treatment of many conditions and diseases used in children are not specifically licenced for such use. They are give "off label". It is a medico-legal issue and the prescriber does it at his/her own risk. Simplistically, this is because trials in children may pose financial and ethical barriers for companies so they will rarely sponsor them unless the potential return is very high.

The market for drugs to treat CVS is quite small and trials can be very expensive. So no drug used to actually treat CVS has ever been licenced for the specific use to treat CVS. Use to treat vomiting in other conditions and situations, e.g. in cancer chemotherapy-induced vomiting may be licenced in adults.

That is why this is big news. The drug is not new, the method of delivery is. To have a clinical trial of a drug specifically in CVS is a big step. This is a long way from it being licenced specifically for this use but it's progress. The trial is recruiting now, and is USA only. One to watch!


Another differential diagnosis

Some childhood onset symptoms that may be diagnosed as CVS, might be a completely different condition. We know CVS symptoms are common to many conditions, and only when they have been ruled out should someone be diagnosed as having CVS.

Jansen de Vries Syndrome was relatvely recently recognised, 2017, and there are diagnostic tests available. Presentation of symptoms is variable but develpmental delay is the most prevalent and repeated vomiting episodes are common.

Currently there is no "cure" and treatment is largely supportive. There is a support group in the USA who can provide more information. It would be sensible to ask your medical support, if this syndrome has been ruled out in those sufferers who display the symptoms listed on the de Vries website.
