• The effects of ibrutinib and PD 0332991 (palbociclib) on the developing human fetus are unknown; for this reason and because tyrosine kinase inhibitors as well as other therapeutic agents used in this trial may be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; female patients who are of non-reproductive potential include the following: post-menopausal by history - no menses for >= 1 year; OR history of hysterectomy; OR history of bilateral tubal ligation; OR history of bilateral oophorectomy); female patients of childbearing potential must have a negative serum pregnancy test upon study entry; male and female patients who agree to use highly effective methods of birth control (e.g., condoms, implants, injectables, combined oral contraceptives, some intrauterine devices [IUDs], complete sexual abstinence, or sterilized partner) during the period of therapy and for 90 days after the last dose of study drug

• 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; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of ibrutinib administration; subjects should be offered the opportunity to bank sperm or eggs prior to initiation of study drug

• Subjects with currently active, clinically significant hepatic impairment (> moderate hepatic impairment according to the National Cancer Institute (NCI)/Child Pugh classification)

(PCR-positive patients will be excluded.)

• Subjects with uncontrolled human immunodeficiency virus (HIV) are not eligible; controlled HIV is defined as a CD4 count > institutional lower limit of normal and no current co-infection; uncontrolled HIV is all other HIV infection; note that patients with controlled infection should be allowed to participate only if they are not receiving prohibited cytochrome P450 (CYP) interactive medications
