Female subjects of childbearing potential must have a negative serum pregnancy test result within 72 hours prior to initiation of trial treatment.

Female subjects of childbearing potential must agree to use a highly effective form of contraception during treatment and for at least 90 days after the final dose of VB10.NEO, and for 5 months after the final dose of atezolizumab, whichever occurs later.

intrauterine device

intrauterine hormone-releasing system

bilateral tubal occlusion

vasectomized partner

sexual abstinence (defined as refraining from heterosexual intercourse during the entire period of risk associated with the trial treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence [calendar, symptothermal, post-ovulation methods], withdrawal [coitus interruptus], spermicides only, and the lactational amenorrhea method are not acceptable methods of contraception).

For men with a female partner of childbearing potential or pregnant female partner: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom during the treatment period and for at least 28 days after the final dose of trial treatment to avoid exposing the embryo, and agreement to refrain from donating sperm.
