Unit 4: Laboratory Techniques and their Application
D: Understand how scientific information may be stored and
communicated in a workplace laboratory.
Pfizer:
One of the most creative biopharmaceutical companies in the world, Pfizer has produced over
150 drugs and vaccines that have improved the lives of millions of people in the UK and around the
world. The business sells drugs to treat a range of conditions, including as cancer, inflammation,
immunological disorders, and rare diseases, as well as problems with the heart, metabolism, and pain.
Contract manufacturing, sterile injectable drugs, biosimilars, active pharmaceutical ingredients (APIs),
and sterile injectable drugs are a few of the services it provides.
Collection of samples and final reports:
A clinical trial is a research study that looks into whether or not a
medical therapy or equipment is safe and effective in humans. It's crucial when it comes to presenting a
new medicine to a patient. A possible new therapy takes an average of 12 years to develop and be
approved for use in a patient, however this period varies substantially depending on the complexity and
effectiveness of the new treatment. Although the creation of a vaccination to treat COVID-19 was
accomplished in an extraordinary time period of less than a year, it is based on research and
development that began 20 years ago, and the EU authorised the first gene therapy. Thousands of data
are generated during clinical development studies and are used by regulatory agencies to assess
whether the drug is approved for use and under what conditions.
Hundreds of thousands to millions of participants are needed for clinical trials. Enrolling in a clinical trial
could give people with incurable diseases access to potentially life-saving treatments. Volunteers are
routinely watched by trial researchers while engaging in such trials, and their involvement will help
others by contributing to medical research. To guarantee participant safety, each study is regulated by
well-defined ethical principles and standards. Computer simulations (in silico studies), cell-based tests (in
vitro studies), and animal experiments are used to evaluate the most promising medications before they
are tested on people (in vivo studies). Only if a chemical satisfies specific safety criteria and shows
promise as a possible new medication can it move on to human clinical testing, often known as 'Phases.'
Phase 1 trials are usually more concerned with ensuring that the drug is safe for human use than
determining its therapeutic efficacy for a particular condition. During this phase, a limited number of
study participants receive increased doses of the investigational drug, allowing researchers to assess the
body's response, including how it is absorbed, how long it stays in the bloodstream, and safely
, acceptable doses. Phase 2 trials evaluate the effectiveness of experimental treatment in the treatment
of specific diseases or conditions. The experimental treatment's safety, side effects, and possible hazards
are also evaluated. Researchers are now attempting to determine the most effective dosages of an
experimental medicine as well as the most successful delivery methods, such as tablets, prolonged
release capsules, infusions, or injections. Phase 2 clinical studies often include a significant number of
patients, perhaps hundreds, who are suffering from the ailment that the experimental medicine is
intended to treat.
Phase 3 trials reproduce the results of previous trials in a large number of populations, allowing
researchers to learn more about the efficacy and safety of experimental medicine. This phase, which
takes place at many research sites, typically involves hundreds to thousands of people. These studies are
frequently randomised, with participants being allocated to either the experimental therapy, a placebo,
or an existing treatment at random. Studies are frequently "double-blind," which means that neither the
investigator nor the participant knows whether the therapy given is an experimental treatment, a
placebo, or an already available medicine. Means. Phase 3 studies frequently give a wealth of
fundamental data for assessing the benefit-risk profile of a new medicine and the therapy that will be
included in the final label if the regulatory body approves it.
The results of clinical trials are submitted to regulatory organisations in order to get a licence before a
medicine is made available to patients. The regulatory approval of new pharmaceuticals is handled by
the UK's Medicines and Healthcare Products Regulatory Agency (MHRA) and the European Union's (EU)
European Medicines Agency (EMA). Following EMA or MHRA approval, health assessment organisations
like the Scottish Medicines Consortium (SMC) and the National Institute for Health and Care Excellence
(NICE) regularly evaluate the accessibility of pharmaceuticals at the NHS. After Phase 4 regulatory
approval, continuous monitoring, also known as "post-marketing surveillance," is required to signal
continued use of treatment. Researchers can participate in these studies and complete the final report
after FDA approval to learn more about long-term risks, benefits, and best practices. Thousands of
people can be involved in these studies, which can extend the life of the drug.
How is data managed/stored:
Information Gathering In general, scientists seek knowledge in the form
of verifiable explanations that can be used to predict the outcome of future research. Information
obtained through observations and experiments is called empirical evidence. This information is
collected and analysed by scientists. Progression is an important aspect of the scientific method, as it
leads to the proof or disproof of the hypothesis and thus to a deeper understanding of the world. The
benefits of collecting scientific knowledge include the ability to spread new ideas faster and more
widely, leading to new research. Scientific knowledge allows us to develop new technologies, tackle
practical problems, and make informed decisions individually and collectively. The scientific approach is
intertwined with the application because the product is so useful. New scientific discoveries can lead to
