Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a study of TAK-951 in participants with cyclic vomiting syndrome (CVS).

The main aims of this study are as follows:

* To check for side effects from treatment with TAK-951.
* To learn how much TAK-951 participants can receive without getting side effects from it.
* To check how much TAK-951 stays in the blood over time to work out the best dose.
* The dose of TAK-951 will be checked to see how much stays in their blood over time.
* To see if it is possible to give treatment at home. Participants will be given TAK-951 injected just under the skin (subcutaneous or SC).
