Phase 1 Trial.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07924761). This is a study registration, not published results. Lead sponsor: Kailera. Recruitment status: NOT_YET_RECRUITING. Phase: PHASE1. Study type: INTERVENTIONAL. Enrollment: 60 participants (ESTIMATED). Conditions: Overweight or Obesity. Interventions: DRUG: KAI-4729. Primary outcome measures: Maximum Observed Plasma Concentration (Cmax) of KAI-4729 in the Upper Arm and Thigh Compared to the Abdomen , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Area Under the Concentration-time Curve From Time 0 to Time of Last Quantifiable Concentration (AUC0-t) of KAI-4729 in the Upper Arm and Thigh Compared to the Abdomen , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Area Under the Concentration-time Curve From Time 0 to Infinity (AUC0-inf) of KAI-4729 in the Upper Arm and Thigh Compared to the Abdomen , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Cmax of KAI-4729 in Healthy Non-Asian and Asian Participants , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Treatment Period 1: Pre-dose and up to 29 days post-dose (Asian Participants); AUC0-t of KAI-4729 in Healthy Non-Asian and Asian Participants , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Treatment Period 1: Pre-dose and up to 29 days post-dose (Asian Participants); AUC0-inf of KAI-4729 in Healthy Non-Asian and Asian Participants , Treatment Period 1, 2 and 3: Pre-dose and up to 29 days post-dose; Treatment Period 1: Pre-dose and up to 29 days post-dose (Asian Participants). Brief summary: The main objectives of this study are to assess the relative bioavailability of KAI-4729 subcutaneous (SC) injection in the upper arm and thigh compared with the abdomen and to measure the pharmacokinetics of KAI-4729 in plasma following a single SC dose in healthy non-Asian and Asian participants.
