NCT06768658

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • Number of Participants Who Experience at Least One Treatment-emergent Adverse Event (TEAE)

    A TEAE was defined as an adverse event (AE) with an onset that occurs after receiving study drug. An AE was defined as any untoward medical occurrence in a clinical investigation participant who has signed informed consent to participate in a study; it does not necessarily have to have a causal relationship with the treatment. An AE could therefore be any unfavorable and unintended sign (example, a clinically significant abnormal vital sign or laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it was considered related to the drug.

    Up to end of study (up to 44 weeks)

Secondary Outcomes (8)

  • Number of Participants With Total Response

    Within 2, 4, and 8 hours post-dose

  • Number of Participants With Absence of Emesis

    Within 2, 4, and 8 hours post-dose

  • Number of Participants With Absence of Significant Nausea

    Within 2, 4, and 8 hours post-dose

  • Peak Nausea VRS Score in All Participants

    At 0, 1 and 2 hours post-dose

  • Peak Nausea VRS Score in Participants Who Did Not Receive the Rescue Medication Before the Evaluation Timepoint

    At 4 and 8 hours post-dose

  • +3 more secondary outcomes

Study Arms (2)

Sequence 1 (ABBA): Placebo + TAK-951 4 mg + TAK-951 4 mg + Placebo

EXPERIMENTAL

Participants will receive TAK-951 placebo-matching injection (Treatment A), subcutaneously, single dose on Day 1 in CVS Episode 1 (Period 1), followed by TAK-951 4 milligram (mg) (Treatment B), injection, subcutaneously, single dose, on Day 1 in CVS Episode 2 (Period 2), further followed by TAK-951 4 mg (Treatment B), injection, subcutaneously, single dose on Day 1 in CVS Episode 3 (Period 3), and further followed by TAK-951 placebo-matching injection (Treatment A), subcutaneously, single dose on Day 1 in CVS Episode 4 (Period 4). A washout period of at least 14 days will be maintained between each Period.

Limitations and Caveats

This study was terminated early and only enrolled one participant that received no treatment. Due to concerns that the participant would be at risk of being re-identified and received no treatment, no data were evaluated and collected to be reported in this study.
