iCP-NI - Safety, Tolerability, Pharmacokinetic, and Immunogenicity Study in Healthy Male and Female Subjects

iCP-NI - A Phase 1, Double Blind, Placebo Controlled, Single and Multiple Intravenous Infusion, Safety, Tolerability, Pharmacokinetic, and Immunogenicity Study in Healthy Male and Female Subjects

This is a Phase 1, double-blind, randomized, placebo-controlled study to investigate single and multiple intravenous infusions of improved cell-permeable nuclear import inhibitor (iCP NI) in healthy subjects.

Study Overview

• Status: Terminated
• Conditions: Healthy Volunteers
• Intervention / Treatment: Drug: iCP-NI; Drug: Placebo

Detailed Description

Improved cell-permeable nuclear import inhibitor (iCP-NI) is a synthetically manufactured, cell-penetrating peptide which has been developed by fusion of advanced macromolecule transduction domain of hydrophobic cell-permeable peptide and nuclear factor kappa-light- chain-enhancer of activated B cells (NF-κB)-derived nuclear localization sequence.

The production and secretion of cytokines from innate immune cells are critical responses to inflammation and infection in the body.

iCP-NI is a binding competitor that inhibits the interaction of nuclear transfer material proteins such as IATF (NF-BB, STAT, AP-1, NFAT) and importin alpha5, inhibiting the nuclear transport of IATF to prevent inflammatory cytokine transcription.

This study is the first-human clinical trial for iCP-NI which is intended to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of iCP-NI.

Prior/concurrent clinical study experience

• Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 30 days (or 5 half-lives, whichever is longer) prior to dosing.
• Have previously completed or withdrawn from this study or any other study investigating iCP-NI, and have previously received iCP-NI.

Diet and lifestyle

• Alcohol consumption of >21 units per week for males and >14 units per week for females. One unit of alcohol equals 12 oz (360 mL) beer, 1½ oz (45 mL) liquor, or 5 oz (150 mL) wine.
• Positive urine drug screen at screening or check-in or positive alcohol urine or breath test result at check in.
• History of alcoholism or drug/chemical abuse within 2 years prior to check in.
• Use of tobacco or nicotine containing products within 3 months prior to check in.
• Ingestion of poppy seed containing foods or beverages within 7 days prior to check-in.

Other exclusions

• Receipt of blood products within 2 months prior to check in.
• Donation of blood from 3 months prior to screening, plasma from 2 weeks prior to screening, or platelets from 6 weeks prior to screening.
• Poor peripheral venous access.
• Subjects who, in the opinion of the investigator (or designee), should not participate in this study.
