Drug Development Life Cycle
Transcript of Drug Development Life Cycle
Drug Development Life Cycle
the study of the distribution and determinants of health-related states or events (inc. disease)
the application of this study to the control of diseases and other health problems.
surveillance and descriptive studies can be used to study distribution
analytical studies are used to study determinants.
efficiency, effectiveness, value and behavior in the production and consumption of health and health care
US increase in antidepressant sales
carried out trials while at sea, 1747
scurvy patients were given the same general diet but this was supplemented with cider, elixir vitriol, vinegar, seawater, nutmeg and (crucially) oranges and lemons
six days later patients taking citrus fruits were fit for duty.
nearly 50 years before the Navy eventually made lemon juice a compulsory part of the seafarer's diet (this was soon replaced by lime juice because it was cheaper)
Selection of Lead Compound
Methodology follows GLP
Drug Delivery Systems
Clinical Trials in Humans:
protocols following GCP

Compliance with regulatory requirements necessary
1. The Pharmaceutical Industry
2. Key Job Roles
3. Product Development Process
Lots of time and money!
can take 12–15 years
costs can be upwards of £1/2bn
ideas for a target can come from a variety of sources
takes years to build up a body of supporting evidence before selecting a target for a costly drug discovery programme.
pharmaceutical companies and academic centres have identify molecules which possess suitable characteristics to make acceptable drugs.

People who are forced by legislation to wear a bicycle helmet, meanwhile, may be different again. Firstly, they may not wear the helmet correctly, seeking only to comply with the law and avoid a fine. Secondly, their behaviour may change as a consequence of wearing a helmet through “risk compensation,” a phenomenon that has been documented in many fields.4 5 One study—albeit with a single author and subject—suggests that drivers give larger clearance to cyclists without a helmet.6
Even if helmets do have an effect on head injury rates, it would not necessarily follow that legislation would have public health benefits overall. This is because of “second round” effects, such as changes in cycling rates, which may affect individual and population health. Modelling studies have generally concluded that regular cyclists live longer because the health effects of cycling far outweigh the risk of crashes.7 This trade-off depends crucially, however, on the absolute risk of an accident: any true reduction in the relative risk of head injury will have a greater impact where crashes are more common, such as for children.8
The impact on all cause mortality, and on head injuries, may be even further complicated if such legislation has varying effects on different groups. For example, a recent study identified two broad subpopulations of cyclist: “one speed-happy group that cycle fast and have lots of cycle equipment including helmets, and one traditional kind of cyclist without much equipment, cycling slowly.” The study concluded that compulsory cycle helmet legislation may selectively reduce cycling in the second group.9 There are even more complex second round effects if each individual cyclist’s safety is improved by increased cyclist density through “safety in numbers,” a phenomenon known as Smeed’s law.10 Statistical models for the overall impact of helmet habits are therefore inevitably complex and based on speculative assumptions.11 This complexity seems at odds with the current official BMA policy, which confidently calls for compulsory helmet legislation.
Lead compound(s) has been optimized and tested and pharmacological studies have been conducted to show it has the potential to become a drug.
Any investigation in human subjects intended to discover or verify the clinical, pharmacological and/or other pharmacodynamic effects of an investigational product, and/or to identify any adverse reactions to an investigational product, and/or to study absorption, distribution, metabolism, and excretion of an

clinical trial application
• Sponsors must apply to and receive approval
from the Medicines and Healthcare products
Regulatory Agency (MHRA) for a Clinical
Trial Authorisation (CTA), and for substantial
• Investigators must apply to and receive
approval from a REC for the protocol and
substantial amendments; the type of REC
depends on whether the trial is in healthy
subjects (Type 1) or patients (Type 2 or 3).
Previously, any REC could review a
phase 1 trial.
• The MHRA and REC must respond to
applicants within 30 and 60 days
respectively. Both must respond to protocol
amendments within 35 days.
Key Opinion Leaders
physicians who influence their peers' medical practice, including but not limited to prescribing behavior
pharmaceutical companies generally engage key opinion leaders early in the drug development process to provide advocacy activity and key marketing feedback.
often KOLs are chosen more for their high prescribing habits than for their knowledge or other attribute that would enable them to influence their peers
physicians are more interested in true thought leaders who have credentials such as
and/or have performed clinical trials.

▼ This medicinal product is subject to additional monitoring.
it contains a new active substance; new medicines or vaccines authorised on or after January 2011 are assigned a Black Triangle
it is a biological medicine, such as a vaccine or a medicine derived from plasma (blood);
it has been given a conditional approval (where the company that markets the medicine must provide more data about it) or approved under exceptional circumstances (where there are specific reasons why the company cannot provide a comprehensive set of data);
the company that markets the medicine is required to carry out additional studies: for instance, to provide more data on long-term use of the medicine, or on a rare side effect seen during clinical trials.
has been in place in the UK for many years to signify medicines that are subject to intensive monitoring
now used in all EU Member States and the list has been agreed Europe-wide
the Black Triangle will start appearing in the package leaflets of the medicines concerned from the autumn of 2013
The MHRA and the Commission on Human Medicines (CHM) run the UK's spontaneous adverse drug reaction (ADR) reporting scheme - called the
Yellow Card Scheme
. This receives reports of suspected adverse drug reactions (ADRs) or side effects from healthcare professionals and patients for medicines and vaccines.
The Yellow Card Scheme is the main ADR reporting scheme in the UK and was introduced in 1964 after the thalidomide tragedy highlighted the urgent need for routine monitoring of medicines. It receives about 25,000 reports of possible side effects each year.

In the European Union (EU), a company may submit a single application to the European Medicines Agency (EMA) for a marketing authorisation (licence) that is valid simultaneously in all EU Member States, plus Iceland, Liechtenstein and Norway. This is called the centralised (or community) authorisation procedure, and is mandatory for certain types of medicines and optional for others.
Each EU Member State has its own procedures for the authorisation of medicines that fall outside the scope of the centralised procedure. Applicants must submit an application to the competent authority of the Member State. In the UK, this is the
Mutual recognition procedure
In the mutual recognition procedure, a medicine is first authorised in one EU Member State.
Countries concerned agree to recognise the validity of the original, national marketing authorisation.
Using the decentralised procedure, companies may apply for simultaneous authorisation in more than one EU country of products that have not yet been authorised in any EU country and that do not fall within the mandatory scope of the centralised procedure.
