Description

Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery.Preclinical research on microbes and animals is part of this process, as is requesting regulatory status, such as through the US Food and Drug Administration, to begin human clinical trials for an investigational new drug. Additionally, it can involve submitting a new drug application to obtain regulatory approval before marketing the medication [1]. It normally takes more than ten years to produce a vaccine or medication from concept to approval, including preclinical research in the lab, clinical trial development, and Phase I to III trials.

New chemical entity development

Pre-clinical: New chemical entities are the substances that are found while developing new drugs. These show promising outcomes against a particular biological target that is important in disease. However, little is known about this NCE's pharmacokinetics, metabolism, toxicity, safety, or pharmacodynamics in people. Drug development is accountable for analyzing each of these aspects before human clinical trials. Another crucial objective of drug development is the suggestion of the dosage and timing for a medicine's first use in a human clinical research [2].

During the drug development process, it is also necessary to establish the NCE's physical properties, such as its chemical composition, stability, and solubility. Producers must optimize they use to make the chemical in order to move from a medical chemist making milligram to manufacturing on a kilogram and tones scale. They also check whether the medicine may be packaged as capsules, tablets, aerosol, and intramuscular, subcutaneous, or intravenous forms. In preclinical and clinical research, these procedures are together referred to as "Chemistry Manufacturing and Control" (CMC).

For many drug development procedures, meeting the regulatory requirements for a new drug application is of utmost importance. Before a novel drug is used on humans for the first time, these usually take the form of a series of studies designed to pinpoint its primary toxicities. Law requires that major organ toxicity be assessed, including how the medicine may affect the heart, lungs, brain, kidney, liver, and digestive system, as well as other bodily systems (e.g., new drug is to be delivered on or through the skin). These early studies are carried out in vitro (for example, with isolated cells), but many of them are limited to employing experimental animals to show the complicated interaction between metabolism and drug exposure on toxicity [3,4].

This preclinical testing's data, along with data on CMC, are gathered and submitted as an Investigational New Drug (IND) application to regulatory bodies. The development process moves to the clinical phase if the IND is certified.

Clinical phase

Clinical trials involve four steps: Phase I trials, frequently involving healthy individuals, establish safety and dose. Phase II studies are used to determine initial efficacy and further investigate safety in a small number of patients with the ailment that the NCE is aiming to treat. Phase III trials are significant, critical studies that must evaluate safety and efficacy in a sufficient number of patients with the targeted ailment. If safety and efficacy have been sufficiently established, clinical testing may come to an end at this point, and the NCE will go on to the New Drug Application (NDA) stage. Phase IV trials, also referred to as post-market monitoring studies, are post-approval trials to which the FDA may from time to time attach requirements. Once an NCE is advanced into human clinical trials, the process of specifying the properties of the medicine continues. Manufacturers must make sure that any long-term or chronic toxicity are well-defined, including impacts on systems not previously tracked, in addition to the tests necessary to introduce a novel vaccine or antiviral medication into the clinic for the first time [5].

Valuation

A drug development project's nature is defined by high attrition rates, significant upfront costs, and protracted schedules. This makes it difficult to value these initiatives and businesses. Not all valuation techniques can account for these specifics. The most popular valuation techniques include decision trees, real options, Risk-adjusted Net Present Value (rNPV), and similar.

The cost of capital or discount rate, phase parameters like duration, success rates, and costs, and expected sales, which includes cost of goods and marketing and sales expenses, are the most significant value drivers. Less objective factors like management quality or technological innovation should be taken into account when estimating cash flows [6-8].

Conclusion

Only 21.5% of medication candidates that started Phase I trials and were covered by a study on clinical research in the 1980s and 1990s were finally approved for marketing. The average success rate from Phase I to successful Phase III trials from 2006 to 2015 was less than 10%, and it was notably 16% for vaccines. The high failure rates involved in pharmaceutical development are referred to as attrition rates, and they force early programme termination in order to avoid major failures.
