Pfizer

About	Pfizer has had a longstanding commitment to ensure that access to clinical trial data is available to regulators, researchers, and trial participants.
How we share on the Vivli Platform	To obtain Pfizer data for analysis on the Vivli platform, data requestors must complete a data request on the Vivli platform. If the request is approved and a Data Use Agreement signed, Pfizer will upload the de-identified data into the Vivli platform for use by researchers in the secure Vivli research environment. For more information about the secure research environment sizes, software and no charge period click here.
Studies available for sharing	Data from Pfizer-sponsored global interventional clinical studies are available from: Trials conducted for medicines, vaccines, and medical devices for indications that have been approved in the US and/or EU. Trials conducted for medicines, vaccines, and medical devices that have been terminated (i.e. development for all indications has been discontinued).
Exceptions	The following are reasons that would preclude granting access in response to a data request: Patient privacy – For example, the request seeks clinical data for which patient de-identification is difficult or for which there is a reasonable likelihood of re-identification, or where there are limitations or restrictions due to privacy rights of individuals in accordance with applicable privacy laws. Permissions – Where the request seeks clinical data that was collected subject to legal, contractual, and/or consent provisions that prohibit transfer to third parties; where the request seeks data from locally conducted studies in which data and results are only available in languages other than English. Where the request is for case narratives, documentation for adjudication, imaging data (e.g. x-rays, MRI scans, etc.), genetic data and exploratory biomarker data. Where there are substantial practical constraints to providing access via the Vivli platform. Data will not be provided to requesters with potential or actual conflicts of interest, including individuals requesting access for commercial, competitive or legal purposes.
When Studies are Available for sharing	Data from trials that meet the criteria above are available 18 months after study completion.
Additional Conditions for Access	Data requests must be from qualified researchers with the appropriate competencies to perform the proposed analyses. Research teams must include a biostatistician.
What information will be provided	Based upon the specific request, the following information may be provided: 🗹 De-identified Individual Patient Data (IPD) 🗹 Protocol 🗹 Statistical analysis plan 🗹 Data dictionary 🗹 Annotated case report forms 🗹 Redacted clinical study reports 🗹 Analytic code

Review Criteria for Data Requests	In addition to taking into account the exceptions and the additional conditions for access noted above, Pfizer will evaluate the following: Is the research question clearly defined with a scientifically valid rationale? Is there a well-documented and rigorous statistical analysis plan? If the proposal includes combining data across different Pfizer trials, is there a clear plan to standardize data sets to ensure they are comparable? Is there an adequate publication plan to disseminate findings in a peer reviewed journal or scientific meeting? Has the applicant certified that the stated research purpose has been declared fully and openly and that the research as described will be conducted and reported in good faith? Is the applicant willing to declare all professional interests, affiliations, possible conflicts of interest, and all sources of support for the research as part of the dissemination of their results? Does the research team have sufficient expertise and qualifications to perform the proposed investigation?
Data Request Review Process	To request access to patient-level data, researchers should submit a scientifically valid research proposal via the Vivli platform.
Access to study documents without participant-level data	Pfizer makes electronic synopses of CSRs publicly available on its website. The electronic synopses include a synopsis of the CSR submitted to regulatory authorities, with data that could be used to identify individual patients removed. Synopses will be posted for trials either initiated after Sept. 27, 2007, or trials initiated on or before that date that were still ongoing as of Dec. 26, 2007. To access the synopses that have been posted to date, please visit https://www.pfizer.com/science/research_clinical_trials/trial_results.
Anonymization Standards	Data will be de-identified in line with the Safe Harbor method pursuant to HIPAA. The basic data sets researchers will access may look different from those submitted to regulators or used in publication(s) due to de-identification. As such, in some cases, researchers may not be able to completely duplicate the results of Pfizer analyses.
