•  Studies where there is reasonable likelihood that patients’ anonymity cannot be maintained. For example in very rare diseases, studies with very low patient numbers or studies performed at a single center.
• When necessary to restrict information to protect commercially confidential information and intellectual property rights on rare occasions.
• Data collected subject to legal, contractual or consent provisions that prevent further sharing of clinical data will be excluded.
• A data request proposal competes with, and/or is in conflict with our publication plan for the research.

The external research request must not extend beyond the limitation of participants’ consent.

🗹 Raw dataset. This is the data collected for each patient in the clinical study.

🗹 Analysis-ready dataset. This is the dataset used for Daiichi Sankyo’s analysis.

🗹 Protocols with any amendments. This describes the objectives, design, methodology, statistical considerations, and organization of a clinical trial and information about all amendments.

🗹 Annotated case report form. This is a blank case report form with descriptions of the data collected and how they are described in the dataset.

🗹 Dataset specifications. This is the meta-data which describes the datasets e.g., variable labels, variable descriptions, code lists, formats.

🗹 Clinical study report. This is the report of efficacy and safety data from the study. It forms the basis of submissions to regulatory authorities such as the Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Pharmaceuticals and Medical Device Agency (PMDA). Documents will be redacted to protect personal data of study participants, study personnel, and Daiichi Sankyo employees, and to protect Daiichi Sankyo’s commercially confidential information and intellectual property rights. Appendices which include patient level data are not included. Daiichi Sankyo will not share case narratives.

• The primary manuscript of the study has been published or accepted for publication.
• Daiichi Sankyo must be able to provide the requested data. For example, some non-interventional (or observational) studies use data from third party databases under license agreements which prevent Daiichi Sankyo from providing access to the data. Researchers may seek access to data directly from these third party databases under similar agreements.
• Daiichi Sankyo must have the legal authority to provide the data. For example, Daiichi Sankyo may not have the legal authority because the medicine has been out-licensed to another company.
• Daiichi Sankyo must consider it feasible to anonymize the data without compromising the privacy and confidentiality of research participants. For example, anonymization of data from studies of rare diseases is more difficult to achieve and will be reviewed on a case-by-case basis.
• There must not be any considerable operational constraints (costs, resource) to providing access to the data.

• Access to data is determined by the Independent Review Panel based on the scientific merit of the research proposal.
• In exceptional circumstances, access to data may be declined by Daiichi Sankyo, for example, where there is a potential conflict of interest or an actual or potential competitive risk.
