How Can Quantum Computing Technology Help In Pharmaceutical R&D?

The early stages of research related to drug discovery, including the identification of a relevant biological target and a viable lead compound, play a crucial role in the overall success of a drug candidate in preclinical and clinical studies. It is also worth noting that the process of drug discovery is extremely demanding, both in terms of capital requirements and time. Moreover, there is always a high risk of failure associated with research and development (R&D) programs and, considering the increasing regulatory stringency, the approval of new drugs has become significantly more difficult. In recent years, quantum computing technology potential has evolved to revolutionize various industries. One such field that stands which aims to get benefited from quantum computing technology is drug discovery. Traditional methods used for drug discovery are time-consuming and resource intensive. On the other hand, quantum technology has capability to process large and complex problems in a shorter period of time. Presently, quantum physics is used for the discovery and development of drugs owing to its capability of screening billions of molecules for specific targets in a short span of time. This procedure reduces the complexity and helps in saving time and cost associated with the drug discovery process. Quantum computing technology is supporting several steps within drug discovery from target identification to lead optimization.

Historical Evolution Of Computational Drug Discovery Approaches

Ancient physicians relied heavily on serendipitous discoveries for identifying ways to successfully treat diseases. Moreover, traditional medicine was primarily derived from natural sources and the knowledge of such therapeutic remedies was passed down either through verbal communication or written records. In the 1950s, synthetic chemistry techniques were introduced, and pharmaceutical researchers could not synthesize / modify therapeutic substances to suit their drug development needs. This approach involved various technologies which significantly accelerated the discovery process and provided the opportunity to identify novel molecules as well. Despite the use of synthetic chemistry techniques, drug discovery still required significant cost and time investments. Further, owing to lack of understanding of how drug molecules were likely to behave in vivo, many lead molecules that progressed into the clinical stages of development had to be discontinued when they failed to demonstrate adequate therapeutic benefit. Advances in computational technologies led to the emergence of various digital approaches for drug discovery. Most of these next generation techniques were based on the integration of computational tools with conventional stages of early-stage pharmaceutical research. One such approach that managed to gain significant popularity within the pharmaceutical industry was the use of high-throughput screening (HTS) and combinatorial chemistry, involving the use of automation technologies and certain software solutions. However, a significant proportion of molecules identified via this process failed to demonstrate therapeutic viability upon further experimentation, often displaying poor absorption, distribution, metabolism, excretion and toxicity (ADME) properties.

Cadd Vs Quantum Computing Technology

The advancements has enabled the development of more advanced in silico approaches, which showed better potential in identifying new drug molecules at a faster rate, enabling significant cost savings compared to the HTS and combinatorial chemistry approach. For instance, the concept of CADD (computer aided drug discovery) was first introduced in the early 21st century, when a particular pharmacological lead candidate was identified using a virtual screening process, wherein various candidate molecules having favorable chemical composition and displaying biological activity were evaluated. Further, it was based on insights obtained from its chemical structure and using molecular docking techniques to figure out its interaction with the relevant biological target. However, these were still time and cost investing techniques. This would take more time to process large and complex molecules.

In order to overcome these problems quantum technology has emerged and became prominent. It is worth mentioning that this approach resulted in the generation of valuable information that had the potential to aid in the development of alternative product candidates. If the lead molecule failed to demonstrate therapeutic benefit at any stage of development. It is estimated that the use of quantum computing in drug discovery has potential to save up to 50% of the expenses incurred on traditional drug discovery.

Quantum Computing Technology In Drug Discovery Overview

Quantum physics is based on the principles of quantum mechanics, a branch of physics that deals with the behavior of particles at the smallest scales. Unlike traditional binary computers which operates either at 0 or 1, quantum computers have quantum bits or qubits which can exist in multiple states simultaneously due to a phenomenon known as superposition. Additionally, qubits can be entangled, allowing the state of one qubit to influence the state of another regardless of the distance between them. These properties enable quantum computers to solve certain problems much faster than classical computers. Currently, quantum computers operate using a hybrid algorithm in which classical computers complete the bulk of the calculations, and quantum processors take few seconds to resolve the problem. With its ability to solve highly complex problems, quantum computing is overcoming the limitations of traditional computers, and is likely to enable significant advances in fields such as pharmaceutical industry.

How much cost is being saved using quantum technologies?

Over the years, various computational tools and services have emerged, enabling the selection, modeling, analysis and optimization of potential lead candidates. The predictive power of quantum technology has proven to be extremely advantageous, allowing researchers to bypass the random screening of billions of molecules across hundreds of biological targets. As a result, players offering quantum computing technology have now become an integral part of the pharmaceutical industry. According to industry experts, almost 30% of the total cost and time invested in developing a new drug can be saved by utilizing such services. Owing to the significant cost benefits offered by such approaches, the adoption of quantum computing software and quantum computing hardware is anticipated to increase in the coming years. Furthermore, the growing number of drug discovery projects, coupled to their rapid progression through various stages of drug discovery, is expected to continue to create an increasing demand for computational services.
