• •WOCBP must agree to use a combination of a hormonal and a non-hormonal contraceptive method or a non-hormonal method alone that is highly effective (with a failure rate of \< 1% per year) during the intervention period and for at least 9 months after the last dose of study intervention, or according to approved local product label requirements for individual chemotherapy agents, whichever is longer.
• •* WOCBP are not permitted to use hormonal contraceptive methods alone as a highly effective method of contraception and must use an additional non-hormonal highly effective method of contraception.
• •* WOCBP participants must also agree not to donate eggs (ova, oocytes) for the purpose of reproduction for the same period. Participants should be advised to seek advice about egg donation and cryopreservation of germ cells before treatment.
• •* Approved methods of birth control are as follows: Hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), Intrauterine device (IUD), Tubal Ligation or hysterectomy, Subject/Partner post vasectomy, and Implantable or injectable contraceptives. . Not engaging in sexual activity for the entire period of risk associated with the study intervention 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.
• •2 Male (as assigned at birth) participants
• •Male (as assigned at birth) participants will be required to always use a latex or other synthetic condom during any sexual activity (eg, vaginal, anal, oral) with WOCBP, even if the participant has undergone a successful vasectomy or if the partner is pregnant or breastfeeding. Male (as assigned at birth) participants should continue to use a condom during the intervention period and for at least 6 months after the last dose of study intervention, or according to approved local product label requirements for individual chemotherapy agents, whichever is longer.
• •Male (as assigned at birth) participants with a pregnant or breastfeeding partner must agree to remain abstinent from sexual activity or use a male condom during any sexual activity (eg, vaginal, anal, oral), even if the participant has undergone a successful vasectomy, during the intervention period and for at least 6 months after the last dose of study intervention or according to approved local product label requirements for individual chemotherapy agents, whichever is longer.
• •Male (as assigned at birth) participants must refrain from donating sperm during the intervention period and for at least 6 months after the last dose of study intervention, or according to approved local product label requirements for individual chemotherapy agents, whichever is longer. Participants should be advised to seek advice about sperm donation and cryopreservation of germ cells before treatment.
• •WOCBP partners of male (as assigned at birth) participants should be advised to use a highly effective method of contraception during the intervention period and for at least 6 months after the last dose of study intervention, or according to approved local product label requirements for individual chemotherapy agents, whichever is longer, for the male participant.
• •Cohort 1 specific criteria:
