KP-10 and Insulin Secretion in Men

December 10, 2018 updated by: Ghulam Nabi, Quaid-e-Azam University

Preliminary Evidence Suggesting That Acute Administration of KP-10 Induces Insulin Secretion in Normal Weight But Not in Obese Men

Induction of insulin secretion by kisspeptin is observed in mouse, pig, rat, and human islets in vitro and in rats, mice and monkeys in vivo, but its mechanism is not fully clear. The present study was designed to investigate the role of KP-10 on insulin secretion in adult healthy and obese men with insulin resistance. The aim of selection of obese persons for the present study was to investigate the effect of acute KP-10 administration in a metabolically challenged condition where the pancreatic beta cells are already highly activated. The long-term objective of this study was to understand the physiological role of kisspeptin signalling in the regulation of insulin secretion in human health and disease.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: obese men
To the 7 obese men, kisspeptin-10 was intravenously administered (0.5µg/kg BW, prepared under sterile conditions), as a bolus in a volume of 1ml. Blood samples from all the individuals were collected for 30 minutes pre and 120 minutes post-KP-10 administration, at 30 minutes interval. The obtained blood was centrifuged and the plasma insulin was measured by ELISA.
Biological: Kisspeptin-10

Experimental: Normal men
To the 7 normal BMI mean, kisspeptin-10 was intravenously administered (0.5µg/kg BW, prepared under sterile conditions), as a bolus in a volume of 1ml. Blood samples from all the individuals were collected for 30 minutes pre and 120 minutes post-KP-10 administration, at 30 minutes interval. The obtained blood was centrifuged and the plasma insulin was measured by ELISA.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in the response of insulin secretion to acute exogenous kisspeptin administration
Time Frame: Each participant was studied up to 4 hours. Blood samples from each individual was collected for 30 minutes pre and 120 minutes post KP-10 administration, at 30 minutes interval.
The blood samples were obtained and analysed for insulin by Enzyme Linked Immunosorbent Assay to know the differential response of insulin secretion to exogenous kisspeptin-10 administration in healthy and obese men.
Each participant was studied up to 4 hours. Blood samples from each individual was collected for 30 minutes pre and 120 minutes post KP-10 administration, at 30 minutes interval.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
