    • 2. Negative hepatitis B surface antigen (HBsAg) test at screening. Positive hepatitis B surface antibody (HBsAb) test at screening, or negative HBsAb at screening accompanied by either of the following
      • * Negative total hepatitis B core antibody (HBcAb).
      • * Positive total HBcAb test followed by quantitative hepatitis B virus (HBV) DNA \<500 IU/mL. NOTE: The HBV DNA test will be performed only for patients who have a negative HBsAg test, a negative HBsAb test, and a positive total HBcAb test.

      • 8. The effects of tiragolumab and atezolizumab on the developing human fetus are unknown. For this reason and because tiragolumab and atezolizumab as well as other therapeutic agents used in this trial are known to be teratogenic, WOCBP must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of the study treatment period, and for 90 days after the final dose of tiragolumab and 5 months after the final dose of atezolizumab. (Refer to Pregnancy Assessment Policy MDACC Institutional Policy # CLN1114).

        • * Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), intrauterine device, tubal ligation or hysterectomy, subject/partner post vasectomy, implantable or injectable contraceptives, and condoms plus spermicide. Not engaging in sexual activity for the total duration of the study and the drug washout period is an acceptable practice; however, periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.
