Budgeting is one of the most critical steps when planning a clinical trial. Clinical trials are complex, multi-phase studies that require significant resources, and understanding the costs associated with each phase is crucial for an accurate clinical trial budget. In this post, we’ll explore the different phases of clinical trials and the key factors that influence their costs, providing insights into how to prepare a comprehensive budget that aligns with your trial’s needs.
Clinical trials progress through phases, each serving a specific purpose, lasting a particular duration, and carrying distinct cost implications. Let’s break down the cost for each phase:
Phase 1 Trials: These trials are designed to assess a drug’s safety and typically involve a small sample of 15-20 participants. The average cost of a Phase 1 clinical trial is around $4 million.
Phase 2 Trials: The drug’s efficacy is tested, often with a larger group of participants. The costs rise considerably, with Phase 2 trials averaging $13 million.
Phase 3 Trials: These pivotal studies involve hundreds or thousands of patients and aim to confirm the drug’s effectiveness across a large, diverse population. They are the most expensive, averaging $20 million or more.
Pivotal Trials: Some pivotal Phase 3 trials, particularly those required for FDA approval, may cost a median of $41,117 per patient.
Each phase of a clinical trial carries its own financial demands, and it is important to allocate funds accordingly based on the trial’s scope.
Aylin Sertkaya and colleagues from Eastern Research Group, Inc., provided these cost estimates in a report submitted to the U.S. Department of Health and Human Services.
The cost of a clinical trial does not solely depend on the phase. Several factors significantly influence the overall budget, making it essential to account for these when planning your clinical trial budget:
Study Size and Recruitment
Geographical Scope
Therapeutic Area
Trial Complexity
Duration and Timeline
Commercial vs. Academic Trials
When preparing your clinical trial budget, it’s vital to forecast the expenses based on the factors outlined above. Here are some key considerations to ensure an accurate budget:
Accurately Estimate Costs by Phase: Start by understanding the average costs of each clinical trial phase and ensure your budget reflects these costs.
Forecast Recruitment and Site Costs: Ensure your budget accounts for the number of patients you plan to recruit and the number of sites involved. Remember to underestimate the costs of recruitment, as slow recruitment can lead to additional infrastructure costs.
Account for Trial Complexity: Trials that involve personalised treatments, rare diseases, or advanced procedures may require more specialised staff, equipment, and longer monitoring periods, which can increase the costs.
Include Regulatory and Logistical Costs: Ensure that your budget includes regulatory submissions, monitoring visits, data management, and patient follow-up costs, which vary depending on the number of countries and sites involved.
Plan for Hidden Costs: Always include a contingency for unexpected costs, such as protocol amendments, regulatory changes, or patient attrition.
Understanding the phases of clinical trials and the factors influencing costs is essential for preparing an accurate clinical trial budget. By taking into account study size, geographical scope, therapeutic area, and trial complexity, you can develop a budget that reflects your study’s true scope and requirements. Accurate budgeting ensures the trial runs smoothly and maximises the likelihood of achieving its objectives within the available resources.
Whether you are conducting an industry-sponsored trial or an academic study, careful financial planning is the key to success in clinical research.

Over the years, the overall cost of the drug development process has been exponentially increasing, prompting the adoption and use of adaptive clinical trial design software. Though there are practical difficulties and barriers in implementing clinical trial solutions, these problems are adequately addressed to overcome these issues as they arise. With advancements in software technologies, further improvements are being made to the software’s adaptive clinical trial design. Despite these progresses, just only a handful of well-established software with various types of clinical trial adaptations is currently available.
A clinical trial protocol is a document which serves as the step-by-step playbook for running the trial. The clinical trial protocol guides the study researchers to run the clinical trial effectively within a stipulated period. The prime focus of the clinical trial protocol is to ensure patients’ safety and data security. [1, 2] As the clinical trial protocol is an essential document for the seamless execution of the clinical trial, reviewing (peer-reviewing) the protocol is essential to ensure the scientific validity/viability/quality of the protocol.
Guest post by Safeer Khan, Lecturer at Department of Pharmaceutical Sciences, Government College University, Lahore, Pakistan Introduction As we move toward 2025, clinical trial regulations are undergoing significant transformation. This shift is being fueled by technological advancements, changing healthcare needs, and an increasing emphasis on transparency and patient safety. In this post, we will explore the key clinical trial regulations shaping the clinical trial landscape, the challenges professionals face, and the strategies they must adopt to navigate this ever-evolving environment.
