Chugai and NTT DATA Demonstrate AI for Clinical Trial Efficiency

Support for Clinical Trial- Documentation and Seamless Data Integration into the Subsequent Process

Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) and NTT DATA Corporation (TOKYO: 9613) have conducted a demonstration test of a solution for improving the efficiency of clinical trial-related document preparation using AI technology from January to June, 2020.

Clinical trial operations require the creation of a variety of documents and procedures from planning to implementation and application for drug approval. NTT DATA has been developing a solution based on the concept of improving the process efficiency of documentation, for example, by automatically creating clinical trial-related documents from a clinical trial protocol1). In this demonstration, Chugai and NTT DATA are collaborating by conducting concept verification, evaluating the usefulness of this solution and identifying future system issues.

Based on the results of this demonstration, NTT DATA aims to provide commercial services of this solution in FY2021. Furthermore, based on the cooperative relationship between the two companies obtained through this demonstration, we will collaborate and accelerate our efforts toward digital transformation of clinical development operations.


New drug development is a process that involves research, collection and analysis of clinical data in clinical trials, and evaluation of efficacy and safety. It usually takes about 9 to 17 years on average to launch a new drug2). Both pharmaceutical companies and medical institutions participating in clinical studies have expended so much effort to ensure the quality of clinical trial activities and data. In addition, efficient development of high-quality clinical trial-related documents is a common challenge among pharmaceutical companies.

NTT DATA is developing a cross-pharmaceutical company/clinical site total solution platform for clinical trials to connect a wide range of clinical trial processes through the most advanced IT technology to help accelerate new drug development.

Under the goal of optimization of all value chains, one of the basic strategies of CHUGAI DIGITAL VISION 20303), Chugai aims at further acceleration of clinical trial processes. Chugai supports NTT DATA’s initiative and conducted the demonstration test jointly with NTT DATA to develop a new solution using AI technology, leveraging Chugai’s extensive experience.

The solution, as one of total solution platforms for clinical trials, allow sequential and comprehensive generation of various clinical trial-related documents (such as informed consent form for patients, statistical analysis plan, case report form to enter patients’ clinical trial data, and clinical study report summarizing the clinical trial results), using data from the protocol as input information, through AI technology, as well as technology components such as ontology4) and semantics5).

Purpose: To identify requirements for solving the challenges in efficient development of high-quality clinical trial-related document, aiming at digital transformation in clinical development activities.

Procedure: To validate the usefulness of the concept to sequentially and automatically generate clinical trial-related documents required for clinical development activities, and to evaluate technology components for realization. Specifically, we compared time required for the preparation of the informed consent form and the case report form (blank) from Chugai’s protocol as input information, using the prototype of the solution, with the actual time spent for the comparable activities in the past.


Period: From January to June 2020

Validation Results: The usefulness of this solution’s concept was successfully validated identifying tasks ahead. The validation results of the effectiveness are as follows:

  • Reduction in time required for the preparation of the informed consent form and the case report form (blank) was 61% and 40% on average, respectively.
  • In both documents, successful automatic generation was demonstrated mostly as planned. In certain parts of the documents where automatic generation was expected to be difficult, reduction in time was proven to be small as predicted.
  • The case report form (blank) had to be corrected manually as appropriate after the automatic generation, which was one of the factors that reduced the reduction effect rate.


Leveraging the technology components validated in the demonstration test, NTT DATA will expand the applicable clinical trial-related documents, provide a standardized template, and implement suggest functions with AI6) and multiple language support functions sequentially in the solution. In addition to the solution, NTT DATA will seek to provide a total solution platform for clinical trials, including the solution for supporting collection and structuring of clinical data. Chugai and NTT DATA are working together toward the digital transformation of clinical development operations and contributing to the creation of a new framework for more efficient drug development.


“Efficient development of high-quality clinical trial-related documents is a common challenge among pharmaceutical companies. We are very pleased that Chugai’s expertise and experience accumulated in clinical development may contribute to the initiative to accelerate new drug development by building a shared clinical trial platform for pharmaceutical companies and medical institutions with the use of AI technology. Under CHUGAI DIGITAL VISION 2030, Chugai has set its goal to be a top innovator that will provide society-changing healthcare solutions by transforming our business. We will continue to actively work with external partners to lead innovation in the healthcare industry.”

Satoko Shisai, Chugai’s Vice President, Head of Digital & IT Supervisory Division


“We sincerely appreciate that we have successfully completed the demonstration test with Chugai aiming toward digital transformation in clinical development activities. We hope that our innovative solutions developed through our collaboration will resolve the common challenge in clinical development activities in the pharmaceutical industry and help build a foundation to ensure the swift delivery of new drugs to patients. NTT DATA is committed to realizing a healthy longevity society and secure and safe living, as well as contributing to the creation of the future society with customers, using advanced IT technology.”
