In the event of any questions, comments or concerns, please write to us at Legal Department, Exelixis, Inc., 1851 Harbor Bay Parkway, Alameda, CA 94502, or at Or, you can call us at 1 (650) 837-7000.

Exelixis appreciates that visitors to our websites may have concerns over their privacy, so we want to share information with you concerning the information we collect and how visitors can limit the use of personally identifiable information beyond the purposes for which they first provided it. We do, however, reserve the right to disclose information during emergencies if safety is at risk, if we are required to do so by law or to comply with valid legal processes (such as a search warrant, subpoena, or court order), or to protect Exelixis’ rights or property, including in the event of a transfer of control of Exelixis or the sale of substantially all its assets.

Please read this entire Statement before using or submitting information to this website. By using this website, you agree with the terms of this Statement and you consent to the collection, use and the disclosure of any information you share in accordance with this Statement. Your use of this website is also subject to its Terms of Use , which are incorporated by reference herein.

Data We Collect And How We Use It

Personally Identifiable Information

Personally identifiable information includes your name, address, email, telephone number, survey information, website registrations or any other information that might reasonably be used to identify you individually. Exelixis collects personally identifiable information from website visitors only when it is voluntarily provided. We may use this information to respond to an email or other inquiry, to help improve our websites and our services, or to send updates or notices about our company that we think may be of interest to you. Except as necessary to operate our websites or respond to Medical Information requests or other specific inquiries, or in the event of a transfer of control of Exelixis or the sale of substantially all its assets (and in all these cases with appropriate confidentiality protections), personally identifiable information will not be sold, rented or exchanged with unaffiliated entities unless you are first notified and expressly consent to such transfer.

Exelixis may also combine the personally identifiable information you provide with other generally or publicly available information to help us identify visitors’ preferences or interests. We may use the information to improve the content of our websites or our products and services. Again, except as necessary to operate our websites or respond to Medical Information requests or other specific inquiries, or in the event of a transfer of control of Exelixis or the sale of substantially all its assets, we do not sell, rent, or otherwise share with unaffiliated entities any personally identifiable information we collect unless you are first notified and expressly consent to such transfer.

Non-Personally Identifiable Information

Separate from the Personally Identifiable Information described above, the Exelixis web server captures the Internet Protocol (IP) addresses of each connection to our websites and the specific web pages visited during that connection. An IP address is a number assigned to your computer by your Internet Service Provider so you can access the Internet. IP addresses may be used to diagnose problems with our server, report aggregate information, determine the fastest route for your computer to use in connecting to the website, and administer and improve the website. Although the IP address and related information collected is stored in the server log files, no individual is authorized to access those files for any purpose other than system maintenance. In addition to IP address, we may also collect information about a visitor’s internet browser, operating system, device used to access our websites, and usage details such as the date and times our websites are accessed. This information may be collected automatically, and may involve the use of cookies, web beacons, and other tracking technologies, as described further below.

We may use this information to help improve our websites and our services by better understanding our audience and by personalizing our website, services, or advertisements. Exelixis may also collect non-personally identifiable information in aggregate form to track data such as the total number of visitors to each page of our websites, and the domain names of our visitors’ Internet Service Providers. We may use this information, which remains in aggregate form, to understand how our visitors use our websites so that we may make them better.


Exelixis does not knowingly collect any personally identifiable information from or about children under 13 years old through this website. However, if the parent or the guardian of a child under 13 believes that the child has provided us with personally identifiable information, the parent or guardian of that child should contact us at if they want this information deleted from our files. Anyone under 18 years old should seek their parent’s or guardian’s permission prior to using or disclosing any personal information on this website.

Cookies, Web Beacons and Online Advertising

As described under “Non-Personally Identifiable Information” above, we or our service providers may use cookies, web beacons or other tracking technologies to collect information passively. Cookies are small data files stored on your device. Web beacons are electronic images that we may use on our websites or communications, and which may be used to deliver cookies, count users who have visited our websites or otherwise understand how you interact with our websites or services.

We may use these technologies to collect information about how you interact with our websites or our communications, and to improve and personalize our websites, services and advertising, including by targeting advertisements to you on third-party websites.

Do Not Track Requests

Your browser may allow you to transmit a “Do Not Track” signal to online services. There is no consensus as to what these “Do Not Track” signals mean, or how to respond to them. Like many other online services, we do not alter any of our online practices when a “Do Not Track” signal is received. For more information about “Do Not Track,” please visit

Data Integrity and Security

Exelixis takes reasonable steps to protect your personally identifiable information as you transmit your information from your computer to our website and to protect your information from loss, misuse and unauthorized access, disclosure, alteration or destruction. We endeavor to keep information transmitted to this website secure to the extent possible using existing and appropriate technology. You should keep in mind, however, that no internet transmission is ever 100% secure or error free. In particular, email sent to or from this website may not be secure, and you should therefore take special care in deciding what information you send to us via email. Moreover, where you use passwords, ID numbers, or other special access features on this website, it is your responsibility to safeguard them.


This website may provide links to other websites as a service to our visitors. These are websites we believe may have helpful information. However, Exelixis does not endorse and is not responsible for the content of third-party websites. Similarly, Exelixis does not have any control over information you may choose to provide to those websites.

The privacy policy described here does not apply to third-party websites, even if they are linked to Exelixis websites. Other Internet websites you visit may have their own privacy policies or no policy at all. Other websites might use personal information differently than our policy permits. We strongly encourage you to review the privacy policies of any website before providing any personal information.

Cross-Border Data Transfers

This website and other websites that link to this Statement are controlled and operated by Exelixis from the United States and are not intended to subject us to the laws or jurisdiction of any state, country or territory other than that of the United States. Any information you provide to us through use of our websites may be stored and processed, transferred between and accessed from the United States and other countries that may not guarantee the same level of protection of personal data as the one in which you reside. However, we will handle your personal data in accordance with this Statement regardless of where your personal data is stored or accessed.

Your California Privacy Rights

California law permits users of our websites who are California residents to request certain information about how their information is shared with third parties for direct marketing purposes.
