laboratory test results are within limits acceptable for elective surgery. Laboratory
results that will need to be obtained within 28 days prior to initiation of study
treatment:
- aspartate aminotransferase (AST), alanine aminotransferas (ALT), total bilirubin,
and alkaline phosphatase (ALP) £ 2.5 x upper limit of normal (ULN.).
- Thyroid-stimulating hormone (TSH) < 13, Patients with a history of a high TSH who
are receiving levothyroxine replacement at the time of eligibility evaluation and
have no clinical evidence of hypothyroidism are eligible.
8. For patients receiving therapeutic anticoagulation: stable anticoagulant regimen
9. Negative hepatitis B surface antigen (HBsAg) test at screening
10. For women of childbearing potential: agreement to remain abstinent (refrain from
heterosexual intercourse) or use contraceptive methods, as defined below: Women must
remain abstinent or use contraceptive methods with a failure rate of < 1% per year
during the treatment period and for 5 months after the final dose of atezolizumab.
A woman is considered to be of childbearing potential if she is postmenarchal, has not
reached a postmenopausal state (³ 12 continuous months of amenorrhea with no
identified cause other than menopause), and has not undergone surgical sterilization
(removal of ovaries and/or uterus). The definition of childbearing potential may be
adapted for alignment with local guidelines or requirements.
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
11. For men: Agreement to remain abstinent (refrain from heterosexual intercourse) or use
a condom, and agreement to refrain from donating sperm, as defined below:
With a female partner of childbearing potential or pregnant female partner, men must agree
to remain abstinent or use a condom during the treatment period and for 5 months after the
final dose of atezolizumab to avoid exposing the embryo. Men must agree to refrain from
donating sperm during this same period

disease, metabolic dysfunction, physical examination finding, or clinical laboratory
finding that contraindicates the use of an investigational drug, may affect the
interpretation of the results, or may render the patient at high risk from treatment
