Description

This guidance was developed to help protect clinical trial participants and patients receiving marketed products from potential adverse effects of pharmaceuticals, while avoiding unnecessary use of animals and other resources.

Key Topics

Terms and concepts identified from this document

Scope & Applicability

Product Classes

5
New Chemical Entities

NCE products requiring structural characterization; Defined in the scope of ICH Q6A

Biotechnology-derived products

dose selection principles described in ICH S6

Finished product formulations

conducted only for formulations that substantially alter pharmacokinetics

locally applied agents

Safety pharmacology studies may not be needed for locally applied agents

cytotoxic agents

Safety pharmacology studies prior to the first administration in humans may not be needed for cytotoxic agents

Stakeholders

2
Clinical trial participants

Guidance developed to help protect clinical trial participants

Patients

Primary source of experience data

Regulatory Context

Regulatory Activities

1
marketing application

sponsors should obtain advice from FDA prior to initiating trials for marketing applications; Clinical trials designed to support a marketing application

Attributes

1
Dose-response relationship

Nature of the PD effect dependency

Technical Details

Substances

3
Active metabolites

Metabolites that exhibit dose-proportional and time-independent PK; redistribution of drug or active metabolites from peripheral tissues

test substance

Effects of the test substance on the autonomic nervous system

Isomeric mixture

testing of individual isomers should be considered

Testing Methods

9
Ligand binding assay

Non-cell-based format that may be appropriate for certain mechanisms of action.

Enzyme assay

Measurement method for enzymes mentioned in comments

Telemetry

Additional ECG assessment for drugs with large QTc prolongation effects

Functional observation battery

used to assess central nervous system effects

Modified Irwin's

test for central nervous system assessment

Electrocardiogram

Used to measure cardiac rhythm

baroreflex testing

used to assess autonomic nervous system effects

heart rate variability

used to assess autonomic nervous system effects

gastric pH measurement

used to assess gastrointestinal system effects

Processes

5
Safety Pharmacology Studies

Studies that investigate potential undesirable pharmacodynamic effects

Toxicology Studies

Pivotal toxicology studies considering disease biology and pharmacology

Comparative metabolism

used to rationally select or design studies

primary pharmacodynamics

Primary pharmacodynamic studies do not need to be conducted in compliance with GLP.

secondary pharmacodynamics

secondary pharmacodynamic studies do not need to be conducted in compliance with GLP

Clinical Concepts

8
Adverse effects

Reported outcomes following the use of a drug or drug class.; provide information to predict potential adverse effects in the target species

Proarrhythmia

common feature of antiarrhythmic agents

QT prolongation

Potential safety concern/adverse effect of some antiemetic drugs.

Crohn's disease

chronic, relapsing, and remitting inflammatory bowel disease; Target disease for drug development; The primary disease state addressed by the guidance.

Primary renal hypertension

patient population consideration for renal function

Autonomic Nervous System

Effects of the test substance on the autonomic nervous system should be assessed.

Gastrointestinal System

Effects of the test substance on the gastrointestinal system should be assessed.

Torsade de Pointes

The thorough QT study is not intended to assess the risk of TdP directly
