Participants with chronic HBV on antiviral therapy or HCV participants who have completed curative anti-viral therapy can be included.
For women of childbearing potential: agrees to remain abstinent (refrain from heterosexual intercourse) or to use contraceptive methods, and agrees to refrain from donating eggs, 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 6 months after the final dose of atezolizumab/pemigatinib/bevacizumab. Women must refrain from donating eggs during this same period.
A woman is considered to be of childbearing potential if she is postmenarchal, has not reached a postmenopausal state (≥ 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 participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of contraception.
For men: agrees to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agrees to refrain from donating sperm, as defined below:
With a female partner of childbearing potential or pregnant female partner, men must remain abstinent or use a condom during the treatment period and for 6 months after the final dose of atezolizumab/pemigatinib/ bevacizumab to avoid exposing the embryo. Men must refrain from donating sperm during this same period.
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 participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not adequate methods of preventing drug exposure.
