Time-to-market (TTM) for a drug is a critical performance metric in the pharmaceutical sector. Despite decades of scientific research and technological advancements, TTM has not significantly improved, leading to prolonged development cycles that diminish a drug’s market value and impact. Reducing TTM not only provides a competitive edge to pharmaceutical companies but also ensures faster access to innovative therapies for patients in need.
Several phases of drug development offer opportunities for accelerating TTM, such as target identification, target-disease mapping, and druggability predictions. Nevertheless, these efficiency gains do not guarantee success at the clinical trials stage. In fact, despite advancements in drug discovery stages, clinical trials remain the biggest bottleneck in drug development pipelines. With up to 90% of drugs failing at this stage, improving clinical trial success rates is the most pressing challenge.
To accelerate progress, the industry is embracing AI-driven clinical research as a solution to improve trial success rates, streamline workflows, and manage multi-modal data at scale.
In this blog, we explore how AI and machine learning (ML) are reshaping clinical research, the key challenges that come with its adoption, and how Elucidata’s AI-ready platform is at the forefront of providing scalable biomedical solutions to mitigate these challenges.
Clinical trials are the cornerstone of drug development, ensuring that new therapies are both safe and effective before widespread use. As soon as a drug is designed and preclinically tested for efficacy and optimization on animal models, it is ready for the clinical trial phase. Typically, the clinical trial process is divided into four key phases, each serving a distinct purpose.
The primary goal of this phase is to determine the safe dosage levels and identify side effects in a small group (20-100) of healthy volunteers. The focus is to evaluate key properties such as how the drug is absorbed, metabolized and excreted.
The main aim of this phase is to assess whether the drug has the intended therapeutic effect by testing on hundreds of patients with the targeted condition. It is typically divided into phase IIa, to measure dose response, and Phase IIb to evaluate drug efficacy.
In this phase, the new drug is compared against existing treatments or placebos, by conducting randomized, controlled, and often double-blind trials on thousands of patients. This stage helps establish clinical benefit and safety at scale, and its successful completion is required for regulatory approval from authorities such as the FDA and EMA.
Even after approval, it is essential to track the drug’s performance in real-world settings to identify long-term side effects, safety concerns, and effectiveness across diverse populations. This step often involves real-world evidence (RWE) collection from patient records, insurance claims, and registries.
Despite the structured approach described above, clinical trials are notoriously slow, costly, and prone to failure, primarily for the following reasons.
Study Design Challenges
Clinical trial success depends heavily on robust study design, yet many trials struggle with hindrances which ultimately contribute to high failure rates and extended timelines.
Patient Recruitment & Retention
Recruiting eligible participants is time-consuming, taking up nearly one-third of the total time of clinical testing. Manual identification using unstructured medical notes, as well as strict selection criteria keep many eligible participants out of testing groups. In fact, many clinical trials struggle to recruit a sufficient number of participants to achieve the statistical power necessary for meaningful and reliable results.
Even after recruitment, high dropout rates extend trial durations and increase overall costs. Retention challenges arise due to long trial durations, logistical difficulties, and lack of patient engagement. Additionally, underrepresentation of diverse populations can impact drug effectiveness across demographics, leading to inequitable treatment outcomes and limiting the generalizability of trial results.
Data Fragmentation & Integration Issues
Clinical trials generate vast amounts of multi-modal data, including Electronic Health Records (EHRs), genomics, imaging, and patient-reported outcomes. However, these datasets are often stored in silos across different systems, making data harmonization and real-time access difficult.
Without AI-ready, harmonized datasets, inefficiencies arise in trial design, patient selection, and data analysis. As a result, many promising drugs fail due to poor patient stratification or inadequate biomarker-driven insights. The inability to efficiently integrate and analyze multi-source clinical data limits the predictive power of trials, contributing to the high failure rate in drug development.
Regulatory & Compliance Hurdles
Navigating complex global regulatory frameworks can significantly delay trial approvals. Researchers must document extensive patient data, often entering dozens of data fields per participant to comply with FDA, EMA, and ICH regulations. While ensuring data integrity, transparency, and auditability is critical, the manual processes involved in regulatory submissions are time-consuming and prone to errors.
Moreover, many clinical trials fail due to regulatory roadblocks, such as:
These inefficiencies add to the already high costs of clinical trials, making drug development financially unsustainable for many promising therapies.
AI and data-driven technologies enable pharmaceutical companies to reduce time-to-market, increase trial success rates, and cut costs.

AI is already improving trial design, patient recruitment, data integration, and regulatory compliance, but its future will be shaped by expanding regulatory acceptance, RWE adoption, and decentralized trials. Regulatory agencies like the FDA and EMA are increasingly relying on RWE for drug approvals, with AI improving real-time patient monitoring, predicting long-term drug safety risks, and accelerating post-market surveillance by detecting adverse events faster. AI is also enabling decentralized and adaptive trials, allowing remote patient monitoring via wearables and supporting dynamic trial adjustments based on interim results. However, widespread adoption will require greater AI explainability and regulatory trust, with a growing emphasis on interpretable models and standardized validation frameworks to ensure compliance and transparency.
As AI in clinical research continues to evolve, the integration of multi-modal data, foundation models, and federated learning will define the next phase of drug development. Companies that invest in scalable, AI-powered data solutions today will be positioned to accelerate time-to-market and drive clinical breakthroughs.
