scientific Advisory Committees

Assisted the FDA in developing guidelines.

Advisory Committees

Specific processes found on the GRP website

Biostatistical consultation

Regulatory Context

Regulatory Activities

6
Phase I

Cancer clinical trials involving dose escalation

Phase II

Advanced stage of environmental impact assessment for higher risk products

Phase III

pertain to Phases I through III of the investigation; Extended trials to confirm efficacy and safety in heterogeneous populations; Clinical testing phases for hypnotic drugs.

Phase I studies

Early clinical trials focused on safety evaluations of new compounds.

Phase II studies

Clinical trials involving patients with incomplete control of seizure disorders.; Studies to demonstrate relative safety and efficacy before extension.

Phase III studies

Large scale trials involving ambulatory and institutionalized patients.

Document Types

1
Study Design

Rigidity varies between Phase I, II, and III.

Attributes

3
safety

evaluating pubertal development for evaluation of safety

effectiveness

alternative would better ensure the effectiveness of the device

Biological availability

Evidence required during Phase I to show the drug is available at the administered dosage.

Technical Details

Substances

1
Barbiturates

Commonly used anesthetic class

Testing Methods

7
Electroencephalography

Adjunctive neurological assessment; Neurophysiologic testing for safety signals

Telemetry

Additional ECG assessment for drugs with large QTc prolongation effects

Absorption and excretion studies

Methods used to present evidence of biological availability during Phase I.

Psychological testing

Suggested if prior studies indicate emotional factors may be affected.

Serum level determinations

Highly recommended for pretest and test drugs to observe interactions.

Hematopoietic tests

Usual safety laboratory tests including platelet estimation.

Pharmacokinetic studies

Used to quantify systemic exposure

Processes

1
Enzyme Induction

Possibility when investigational drug is given with barbiturates.

Clinical Concepts

6
Seizure disorders

The primary medical condition addressed by the antiepileptic drug therapy.

Children

Subject population requiring additional safeguards in research

Adults

Target population for the prevention of PONV in this guidance.

Status epilepticus

An acute seizure situation that may require modification of the guidelines.; Adequate safety precautions must be taken to prevent and treat this.

Generalized tonic-clonic seizures

A specific seizure type also referred to as grand mal seizures.

Infantile spasms

Seizure type restricted to the young-age period.

Standards & References

External Standards

1
International Classification of Epileptic Seizures

The standard used for the classification of seizures in patient selection.; Used for classification of seizure types in trials.

Specifications
