1. Adults =18 years of age;
2. Patient population:
Cohort 1 (R/R DLBCL):
a) Histologically confirmed diagnosis of de novo TP53^wt ABC (non-GCB) or GCB DLBCL based on 2016 WHO Classification;
i) Phase 2: 25 or more subjects with non-GCB and 10 or more subjects with double-expressor lymphoma will be enrolled as described in Section 10.2 of the study protocol;
b) R/R DLBCL after treatment with at least 2 prior lines of systemic therapy or at least 1 prior line of systemic therapy in subjects who are ineligible for hematopoietic stem cell transplantation (autologous or allogeneic) for reasons other than active disease;
c) At least 1 measurable site of disease on computed tomography (CT) (defined as >1.5 cm in longest transverse diameter of a lesion [LDi]) and clearly measurable in 2 perpendicular dimensions);
Cohort 2 (R/R CLL):
d) Histologically confirmed diagnosis of TP53^wt CLL according to iwCLL criteria;
e) Previously treated with at least 1 prior regimen according to
current guidelines;
f) Active disease meeting at least 1 of the iwCLL 2008 criteria for
requiring treatment;
3. ECOG performance status of 0 to 2;
4. Adequate hematologic function independent of growth factor support for at least 7 days with the exception of pegylated G-CSF and darbepoetin which require at least 14 days, defined as:
a) Absolute neutrophil count (ANC) =1,000/mm^3;
b) Platelet count =50,000/mm^3;
5. Adequate hepatic function within 28 days prior to first dose defined as:
a) Total bilirubin within normal limits (WNL); if total bilirubin is > upper limit of normal (ULN) then patients are eligible if the direct bilirubin is =2.0 x ULN;
b) Aspartate transaminase/serum glutamic oxaloacetic transaminase (AST/SGOT) and alanine transaminase/serum glutamic pyruvic transaminase (ALT/SGPT) =2.5 ULN;
6. Adequate renal function within 28 days prior to the first dose defined as an estimated creatinine clearance =30 mL/min by Cockcroft Gault;
7. Female subjects of childbearing potential and their male partners, or male subjects who have female partners of childbearing potential must both use an effective contraception method during the study. In addition, both male and female subjects must continue to use contraception for 6 months after the last dose of study drug. Effective birth control for males includes either vasectomy or use of condoms. Effective birth control for females includes (a) combined estrogen- and progestogen-containing hormonal contraception (oral, intravaginal, transdermal); (b) intrauterine device combined with a barrier method; (c) intrauterine hormone-releasing system combined with a barrier method; (d) bilateral tubal occlusion or ligation; (e) vasectomized partner; and (f) sexual abstinence, when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
Note: Marketed drugs administered concomitantly in this study may have
different contraception requirements, including required duration of
contraception use. The contraception requirements in the prescribing
information (PI) or summary of product characteristics (SmPC) must be
followed for all concomitant drugs administered in this study.

10. Subjects with uncontrolled bacterial, fungal, parasitic, or viral infection. Subjects with acute bacterial infections requiring antibiotic use should not enroll until the infection is stable in the judgement of the treating physician; these subjects may be on antibiotics at time of enrollment;

15. Phase 2 only: Requires treatment with a strong CYP3A inhibitor/inducer within 7 days prior to first dose of study drug;
16. Requires treatment with proton-pump inhibitors (eg, omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, or pantoprazole). Subjects receiving proton-pump inhibitors who switch to H2-receptor antagonists or antacids are eligible for enrollment to this study provided the proton pump inhibitor is discontinued at least 5 days prior to first dose of study drug;
