This document provides an overview of product development from a regulatory perspective. It discusses the steps required to prove a product is safe and effective, including preclinical studies, investigational new drug application, clinical trials in phases 1-3, and the marketing application. The target product profile and good practices for manufacturing, clinical research, and laboratories are also covered. The goal is to help maintain high ethical standards and show favorable risk-benefit analysis for approval.
2. Product Development Overview
Prove the product is safe and effective for the proposed indication
Pharmaceutical products are developed to help treat patients. Always
remember that the patients are people and product development
must maintain a very high ethical standard.
Risk/benefit
You also have to remember
~$1 - $5 billion taking into account failed products
Highly variable
Drugs for large populations cost more than drugs for rare diseases
Novelty
Hurry up and fail
5. An API before and after development
10 years,
$1 bil later
An API into preclinical studies API after obtaining marketing approval
Products do not change during the course of development, you
are just learning more about it.
6. Target Product Profile (TPP)
The TPP is a document describing the goals and objectives of a
product.
It includes a lot of information that will end up on the final label:
Indication and usage
Intended population
Dosage and administration
Dosage form/strengths
Acceptable adverse reactions
Expected or acceptable efficacy
Risk/benefit analyses
It is a living document and expected to be changed as testing
progresses

GLP - Good Laboratory Practices
GCP - Good Clinical Practices
GMP - Good Manufacturing Practices
GDP - Good Documentation Practices (more common in the US)
Lesser used GXP
GDP Good Distribution Practices (more common in Europe)
GRP - Good Review Practices (used by FDA)
GCLP Good Clinical Laboratory Practices

31. Good Manufacturing Practices (GMP)
GMPs are meant primarily for the manufacturing process, testing,
packaging, and labeling of pharmaceutical substances and products.
GMPs are defined in the regulations under 21 CFR 211 for finished
pharmaceuticals. Ensure products are manufactured as to be safe and
effective.
Helps prevent products from getting contaminated and helps to
ensure products do what they are supposed to do.
32. Examples of FDA GMP Guidance Documents

33. Good Clinical Practices (GCP)
Good Clinical Practices (GCP) are meant primarily for the conduct of
clinical studies using any pharmaceutical products.
GCP principles are stated in the laws and regulations which govern
clinical studies. All clinical studies must comply with these GCPs.
An international organization known as ICH published the most
popular and most used GCP guidance (ICH E6)
Ensures clinical studies are conducted ethically and human subjects
are protected
Ensures the scientific integrity of the study
http://www.fda.gov/scienceresearch/specialtopics/runningclinicaltrials/default.htm
34. Examples of FDA GCP Guidance Documents
ICH E6 Good Clinical Practice
ICH E3 Structure and Content of Clinical Study Reports
ICH E9 Statistical Principles for Clinical Trials
Adaptive Design Clinical Trials for Drugs and Biologics
Alzheimers Disease: Developing Drugs for the Treatment of Early
Stage Disease
Standards for Clinical Trial Imaging Endpoints
35. Good Laboratory Practices (GLP)
Good Laboratory Practices are mentioned by name in the regulations
(21 CFR 58)
Meant primarily for animal (in vivo) studies, but may also be
referenced for the isolated cell (in vitro) studies
Ensures quality study design and the study is conducted in an ethical
and appropriate matter
Ensure scientific integrity of the data collected
36. Examples of FDA Preclinical Development
Guidance Documents
Good Laboratory Practices Q&A
ICH S1A The Need for Long-term Rodent Carcinogenicity Studies
ICH S2 Genotoxicity
ICH S3 Toxicokinetics/pharmacokinetics
ICH S4 Chronic Toxicity

Immunogenicity Evaluation of INDs
Nonclinical Safety Evaluation of Drug or Biologic Combinations
Safety Testing of Drug Metabolites
37. Good Documentation Practices (GDP)
GDPs is an industry term used to define how documentation should
be done in a regulated environment
Applies to all disciplines: manufacturing, preclinical, and clinical
Ensures all information is captured accurately and all changes are
captured and traced.
Mostly applies to handwritten documents (batch records,
handwritten medical records, or handwritten results from assays).
For electronic documentation, a different term is usedPart 11
ALCOA (attributable, legible, contemporaneous, original and accurate)
38. Other Examples Useful Guidance Documents
