Immunological Effect of Increasing Doses of Natural Peptide

June 7, 2022 updated by: Gitte Jensen, Ph.D., Natural Immune Systems Inc

Clinical Proof-of-concept Study on Immunological Effects of Consuming Increasing Doses of a Natural Peptide in Healthy Volunteers

A trial monitoring the immune effects in 24 people with 4 different doses (1 gram per day, 2 grams per day, 4 grams per day, 8 grams per day) of a natural plant-based protein hydrolysate.

Study Overview

Detailed Description

The goal for this clinical proof-of-concept study is to compare immune effects of a novel plant-based peptide on IL-17, Th17 and related immunological mechanisms.

An open-label, escalating dose study design monitoring immune effects in which healthy men and women take doses of a natural protein hydrolysate daily for 6 weeks.

During the first 2 weeks, participants will consume 1 gram/day. For the next 2 weeks, participants will consume 2 grams/day. For the final 2 weeks, participants will be randomly assigned to consume either 4 grams/day or 8 grams/day.

Blood samples are collected at baseline and every 2 weeks. The blood will be used for testing of the numbers of T lymphocytes that secrete Interleukin-17 after ex vivo cell cultures.
