ICH S7A PDF

Key aims of safety pharmacology[ edit ] The aims of nonclinical safety pharmacology evaluations are three-fold: To protect Phase I clinical trial volunteers from acute adverse effects of drugs To protect patients including patients participating in Phase II and III clinical trials To minimize risks of failure during drug development and post-marketing phases due to undesirable pharmacodynamic effects The following key issues have to be considered within safety pharmacology: [4] The detection of adverse effects liability i. The only detailed guidelines indicating the requirements from drug regulatory authorities for general pharmacology studies were from the Ministry of Health, Labour, and Welfare. Early compound profiling can flag for receptor-, enzyme-, transporter-, and ion channel-related liabilities of NCEs e. Classically in vivo investigations comprise the use of young adult conscious animals. Study design[ edit ] Safety pharmacology studies have to be designed for defining the dose-response relationship of the adverse effect observed.

The only detailed guidelines indicating the requirements from drug regulatory authorities for general pharmacology studies were from the Ministry of Health, Labour, and Welfare. Early compound profiling can flag for receptor-, enzyme-, transporter-, and ion channel-related liabilities of NCEs e. Classically in vivo investigations comprise the use of young adult conscious animals. Study design[ edit ] Safety pharmacology studies have to be designed for defining the dose-response relationship of the adverse effect observed.

Justification should be provided for the selection of the particular animal model or test system. The time course e. Generally, the doses eliciting the adverse effect have to be compared to the doses eliciting the primary pharmacodynamic effect in the test species or the proposed therapeutic effect in humans. Regulatory guidance documents current versions [ edit ] The primary reference document for safety pharmacology is ICH S7A, followed by many key regulatory documents which either focus on or mention safety pharmacology: ICH S7A: Safety pharmacology studies for human pharmaceuticals.

ICH S7B: Nonclinical evaluation of the potential for delayed ventricular repolarization QT interval prolongation by human pharmaceuticals.

ICH S9: Nonclinical evaluation for anticancer pharmaceuticals [4]. ICH M3 R2 : Guidance on nonclinical safety studies for the conduct of human clinical trials and marketing authorisation for pharmaceuticals. Adopted by CHMP. FDA U. Guidance for Industry. Assessment of abuse potential of drugs. Final Guidance. Exploratory IND studies. See also[ edit ] SPS: There is a global scientific society fostering best practice within the discipline of safety pharmacology. This Safety Pharmacology Society SPS promotes knowledge, development, application, and training in safety pharmacology.

CiPA: Comprehensive in vitro Proarrhythmia Assay [10] : In the coming years, the FDA plans to update the current regulatory documents for preclinical and clinical safety evaluation of proarrhythmic risk in human i. The Comprehensive in vitro Proarrhythmia Assay CiPA is a novel safety pharmacology paradigm intending to provide a more accurate assessment of cardiac safety testing for potential proarrhythmic events in human.

The CiPA includes in vitro assays coupled to in silico reconstructions of cellular cardiac electrophysiological activity with verification of relevance through comparison of drug effects in human stem cell-derived cardiomyocytes. If these evaluation efforts succeed, CiPA will become a Safety Pharmacology screening tool for drug research and development purposes.

In conscious or anesthetized animals HERG and Purkinje studies in vitro Respiratory system studies: whole body plethysmography Vivotecnia continuously incorporates improvements, always trying to deliver optimum service to its customers at a competitive price. This philosophy has led Vivotecnia to further expand its portfolio of safety pharmacology services by adding cardiovascular safety evaluation in conscious telemetry-implanted animals to the already well-established Irwin test. Telemetry systems allow the animal under study to move freely while data are monitored and collected. The effects of each new substance on other important physiological functions in addition to the three principal physiological systems must also be tested. Our in-house colonies of preimplanted animals allow you to start studies quickly and meet optimal deadlines.
