This site is intended for use by residents of the United States only.
We reserve the right to change this Policy without prior notice. You can determine when this Policy was last revised by referring to the “Last Updated” legend at the top of this page. Any changes to our Policy will become effective upon our posting of the revised Policy on the Site. Use of the Site following such changes constitutes your acceptance of the revised Policy then in effect.
1. What Types of Information Does Eisai Collect?
Eisai gathers three basic types of information: “Personally Identifiable Information” (or “PII”), “Non-Personally Identifiable Information” (or “Non-PII”) and “IP Addresses”. Personally Identifiable Information is information that identifies you as an individual, such as your name, postal address, telephone number, email address, financial account number, etc.). Non-Personally Identifiable Information is aggregated information, demographic information and any other information that does not reveal your specific identity. An IP Address is the Internet Protocol address of the computer that you use to access the Site.
a. Personally Identifiable Information. You may explore the Site without providing us with PII, but in order for you to use and benefit from certain features of the Site (such as to request information or to contact us through the Site), we will need to collect certain of your PII. We may also collect PII from you if you participate in our surveys or research, and we may collect similar information from third parties.
b. Non-Personally Identifiable Information. We may collect Non-PII that you submit or that we receive (such as aggregated demographic information, including age or gender, and information on your interests and professional activities) from our customers and from third parties. Eisai and third parties with whom Eisai has contracted to provide services to Eisai also may collect Non-PII from you through browser navigational tools; cookies; pixel tags and other similar technologies.
i. Browser Navigational Tools. We and our service providers may certain technology data, such as your computer type (Windows or Macintosh), screen resolution, Operating System (“OS”) version, Internet browser, and Internet browser version. This type of Non-PII is collected by most browsers, and can be used to optimize your experience on the Site.
ii. Cookies. We and our service providers may use “cookies” on the Site. A cookie is a bit of information that a Website sends to your Web browser that helps the site remember information about you and your preferences. There are two principle types of cookies:
• “Session” cookies are temporary bits of information that are used to improve Website navigation, block Website visitors from providing information where inappropriate and to collect aggregate statistical information on a Website. These cookies are erased once you exit your Web browser or otherwise turn off your computer.
• “Persistent” cookies are more permanent bits of information that are placed on the hard drive of your computer and stay there unless you delete the cookie. Persistent cookies store information on your computer so that we can, for example, retrieve information you have previously provided (such as passwords); better determine what areas of the Site you find most valuable; and customize the Site based on your preferences on an ongoing basis.
You can set your browser to accept all cookies, to reject all cookies, or to notify you whenever a cookie is offered so that you can decide each time whether to accept it. To learn more about cookies, please visit
iii. Pixel Tags. We and our service providers may also use so-called “pixel tags,” “web beacons,” “clear GIFs” or similar technologies (collectively, “Pixel Tags”) in connection with some Site pages and HTML-formatted email messages to, among other things: track the online activity of Site users and email recipients (including activity on other Websites); determine the success of marketing campaigns; and compile aggregate statistics about Site usage and response rates.
iv. Other Sources. Eisai also may collect Non-PII (such as indications of your interests, your geographic location, and other demographic Non-PII) that you or others provide, and we also may aggregate PII in a manner such that the end-product does not personally identify you or any other individual and so is Non-PII. For example, we might aggregate PII to calculate the percentage of our users who have a particular telephone area code, or to better understand certain medical usage patterns. Such aggregate information is considered Non-PII for purposes of this Policy.
c. IP Addresses. Your IP Address is a number that is automatically assigned to the computer that you are using by your Internet Service Provider (“ISP”). This number is identified and logged automatically in our server log files whenever users visit the Site, along with the time(s) of such visit(s) and the page(s) that were visited. Collecting IP Addresses is standard practice on the Internet and is done automatically by many Websites.
2. How Does Eisai Use Information Collected Through the Site?
a. Personally Identifiable Information. We may use PII about you for any or all of the following purposes:
i. Fulfillment of Requests. We may use PII about you to fulfill your requests, such as to send you information, fulfill a purchase order, or set up and conduct interviews.
ii. Administrative Communications. We may use your PII to send you important information, such as changes to our terms, conditions, and policies and/or other administrative information. Because this information may be important, you may not opt out of receiving such communications.
iii. Other Communications. We may use your PII to inform you of products, programs, services and surveys that we believe may be of interest to you. You may opt out of receiving such communications, as described in the Section 4 (“Choices”) below.
iv. Research. We may use the information we collect to conduct surveys, to identify and recruit individuals to participate in our research programs, to interview individuals relating to our research, to create directories and compile databases of contact information, and to provide payment to individuals who receive honoraria.
v. Careers. If you apply for employment with Eisai, any PII about you which is obtained by us during the application process may be used and retained by us for purposes of considering your application for employment, as well as for more general management and research purposes.
vi. Internal Business Purposes. We may also use PII about you for our internal business purposes, such as data analysis, audits, developing new products, enhancing our website, improving our services, identifying usage trends and determining the effectiveness of our promotional campaigns.
b. Non-Personally Identifiable Information. As noted above, we and our service providers may use tracking technologies, such as cookies and Pixel Tags, to improve the usefulness and value to you of our site, as well as to gauge the success of marketing initiatives and to improve our marketing campaigns, by tracking your online visits to our Websites and other Websites not operated by us. For example, we may use such technologies to remind you of Eisai products when you are browsing another Website or may collect aggregate information about other Websites you have browsed. We reserve the right to use non-PII for any other purpose as well. For example, we may use aggregated health information to publish reports on particular topics. In some instances, we may combine Non-PII with PII (such as embedding email addresses in cookies). If we do combine any Non-PII with PII, the combined information will be treated by us as PII for so long as it is so combined.
c. IP Addresses. We use IP addresses for purposes such as calculating Site usage levels, helping diagnose server problems, ensuring appropriate access rights by authorized users, facilitating Site security, and administering the Site. We treat IP Addresses, server log files and related information as Non-PII, except where otherwise required under applicable law.
