          -  For female patients of childbearing potential and male patients with partners of
             childbearing potential, agreement (by patient and/or partner) to use highly effective

             when used consistently and correctly) and to continue its use for 5 months after the
             last dose of ATEZOLIZUMAB. Women must refrain from donating eggs during this same
             period

               -  A woman is considered to be of childbearing potential if she is postmenarcheal,
                  has not reached a postmenopausal state (>/= 12 continuous months of amenorrhea
                  with no identified cause other than menopause), and is not permanently infertile
                  due to surgery (i.e., removal of ovaries, fallopian tubes, and/or uterus) or
                  another cause as determined by the investigator (e.g., Mullerian agenesis). The
                  definition of childbearing potential may be adapted for alignment with local
                  guidelines or regulations.

               -  Examples of contraceptive methods with a failure rate of <1% per year include
                  bilateral tubal ligation, male sterilization, hormonal contraceptives that
                  inhibit ovulation, hormone-releasing intrauterine devices, and copper
                  intrauterine devices.

               -  The reliability of sexual abstinence should be evaluated in relation to the
                  duration of the clinical trial and the preferred and usual lifestyle of the
                  patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or
                  postovulation methods) and withdrawal are not acceptable methods of
                  contraception. If required per local guidelines or regulations, locally
                  recognized acceptable methods of contraception and information about the
                  reliability of abstinence will be described in the local Informed Consent Form.
