• Patient enrolled into the eprenetapopt + venetoclax study should use an effective form of contraception for up to 30 days after the last dose of eprenetapopt in combination with venetoclax, whichever time period is longer. Recommended methods of highly effective birth control are:
• * Hormonal contraception (birth control pills, patches, or rings)
• * Intrauterine device (IUD)
• * Birth control injections
• * Double barrier methods (diaphragm with spermicidal gel or condoms with birth control foam)
• * Sterilization of participant or partner ("tubes tied" or vasectomy)
• Disease free of prior malignancies with exception of currently treated basal cell, squamous cell carcinoma of the skin, carcinoma "in situ" of the cervix or breast, or other malignancies in remission (including prostate cancer patients in remission from radiation therapy, surgery or brachytherapy), not actively being treated, with a life expectancy \> 3 years. Principal investigator (PI) could use judgment in the best interests of patients
• Any serious uncontrolled medical condition including but not limited to, uncontrolled hypertension, diabetes mellitus, active/symptomatic coronary artery disease, chronic obstructive pulmonary disease (COPD), renal failure, active infection, active hemorrhage, laboratory abnormality, or psychiatric illness that places the patient at unacceptable risk and would prevent the subject from signing the informed consent form

Washout period for targeted agents is 2 weeks or 5 half-lives (t1/2) (whichever is shorter). Washout period for antibody-based immunotherapies or cellular therapies is 4 weeks.
