Rat models mimic human disease owing to certain similarities in their pathology to disease conditions that are similar in humans. Under specific conditions, the recurrence and progression of rat diseases are identical to that of humans. The notable anatomical and physiological similarities between rats and humans have encouraged researchers to investigate a broad spectrum of mechanisms and evaluate novel therapies in these research models.

For instance, in oncology research, the rat model-based research assists in understanding the genetic basis of cancer and the role of different genes & gene mutations in the development and progression of cancer that further facilitates the development of antineoplastic medications. These models are employed to study diseases such as hypertension, diabetes, Parkinson's disease, Alzheimer's disease, an acquired immunodeficiency syndrome (AIDS), and muscular dystrophy among other diseases. Thus, the similarities between rats and humans increase their acceptance in disease studies, further fuelling the rat model market growth.

Rat model can be defined as a non-human and living, a genetic-engineered animal that is used for the scientific research purpose and investigation of human diseases. Also, these rat models are used for the purpose of better understanding of the human disease process without harming an actual human.

However, several regulatory bodies are highlighting concerns regarding rat testing that in turn has led to the development of guidelines for optimal rat welfare and usage during biomedical research. The regulatory bodies were established after the pressure from several animal protection organizations and enacted several laws to facilitate the care and usage of laboratory rat testing.

Furthermore, animal organizations such as People for The Ethical Treatment of Animals (PETA), Cruelty Free International, and others are opposing the use of rat models in research. Also, this opposition has led to the establishment of animal welfare acts including the Cruelty to Animals Act that aids in the prevention of unnecessary animal pain and suffering. Thus, the growing opposition to the use of rat testing in biomedical research may reduce the usage of rats.

The emergence of COVID-19 is an unprecedented public health concern that has positively impacted the rat model market share. The coronavirus outbreak has affected the healthcare industry through financial adversities on the health facilities as well. The healthcare sector was also largely affected by the increasing prevalence of COVID-19 cases. Although, heavy investments in research activities related to COVID-19 and the increased funding towards R&D activities to innovate novel therapeutics have promoted the use of rat testing despite the pandemic.

Several pharmaceuticals, biotechnology companies and clinical research organizations revised their R&D spending for clinical trials in comparison to earlier spending, demonstrating the magnitude of disruption caused by the pandemic. While the clinical trials concerning COVID-19 were booming, rapid recovery was observed due to the proliferation of new clinical trial approaches to promote antiviral drug and vaccine development.

Furthermore, to minimize the adverse effect of the pandemic, the organizations that operate traditionally have enabled themselves for collaboration opportunities to expand the capability to support hybrid models. These developments helped to continue clinical research & development activities, ensuring the inflow and the use of rat models, further facilitating the rat model market growth.

Rat Model Market Analysis

The increasing number of pharmaceutical research and development activities is anticipated to drive the rat model market in the coming years. Innovative medications serving to meet the unmet therapeutic requirements are amongst the significant value drivers of research-based pharmaceutical & biotechnology companies.

The pharmaceutical sector develops several innovative medicines that deliver valuable clinical advantages. The growing number of investments by government as well as private players are amongst the key factors boosting the number of pharmaceutical R&D activities. For instance, the Congressional Budget Office evaluates trends in expenditure for drug research and development (R&D) and the commercialization of novel molecules.

According to the Congressional Budget Office, in 2019, the pharmaceutical sector spent USD 83 billion on R&D activities. Those expenditures encompass a comprehensive spectrum of activities, such as discovering & testing novel medications, developing incremental improvements including product extensions, and testing for safety-parameters or regulatory purposes. This amount associated with pharmaceutical R&D activities is approximately 10-fold times higher as compared to the industry spending in the 1980s, further highlighting the increased R&D volume and investments. As a result, the rising research volume and investments in pharmaceutical R&D are set to drive the adoption of rat models in these activities.

The research & development segment held the largest market share in 2021 and is expected to grow at a notable pace to reach over USD 1,648 million by 2028 owing to the increasing number of research & development projects, rise in the investment to innovate novel therapeutics, etc. Rat models are developed to feature some of the earliest developments related to the disease and to detect potential drug targets.

Furthermore, the pharmacokinetic and pharmacodynamic experiments are conducted for evaluating gastrointestinal absorption, distribution, metabolism, and drug excretion (ADME) parameters for every candidate drug. Rat model-based research is extensively employed in these ADME studies that aid in screening these lead candidates to move forward to the next step in safety and efficacy studies. This assists to eliminate some candidate drugs, further helping in substantial costs savings. Thus, the increased use of rat models in R&D is expected to drive the rat model market growth.
