Inclusion Criteria

1. Diagnosis of relapsed/refractory DLBCL as documented by medical records and with histology based on criteria established by WHO:
a. If a subject has de novo DLBCL, the diagnosis is confirmed by biopsy and is immunohistologically characterized as de novo non-GCB DLBCL or de novo GCB DLBCL. Note that PMBCL is excluded from this protocol. Tumor tissue must also be available for sending to the sponsor for central cell of origin testing.
b. If the subjects has RS, the diagnosis is confirmed by biopsy and is immunohistologically characterized as
transformation to DLBCL. Tumor tissue must also be available for sending to the sponsor for central pathology
testing. This histology applies to Part 1 only.
c. If the subjects has transformed DLBCL, the diagnosis is confirmed by biopsy and is immunohistologically
characterized as transformation to DLBCL from indolent lymphoma (eg, follicular lymphoma). Tumor tissue must also be available for sending to the sponsor for central pathology testing. This histology applies to Part 1 only.
2. Men and women =18 years of age.
3. Prior treatment for lymphoid malignancy:
a. If the subject has DLBCL, there is no curative option with conventional therapy and the prior treatment included = 1 prior combination chemoimmunotherapy regimen (eg, anthracycline based therapy with rituximab such R-CHOP). Also subjects should have relapsed after ASCT or should be noncandidates for ASCT.
b. If the subject has RS, the subject must have had =1 prior treatment with a combination chemoimmunotherapy regimen.
4. Presence of radiographically measurable lymphadenopathy or extranodal lymphoid malignancy (defined as the presence of a =1.5 cm lesion, as measured in the longest dimension by CT scan for all histologies).
5. Documented active disease that is relapsed or refractory defined as:
a. Relapse: disease progression after completion of the treatment regimen preceding entry into the study.
b. Refractory: progressive disease or stable disease as best response at any point during chemotherapy (>4 cycles of first-line or 2 cycles of later-line therapy) or relapsed at =12 months from autologous stem cell
transplantation (Crump et al 2017).
6. ECOG performance status of =2.
7. Adequate hematologic function, independent of transfusion and growth factor support for =14 days before
screening, defined as:
a. ANC >1000 cells/mm3 (1.0 x 109/L)
b. Platelet count >75,000 cells/mm3 (75 x 109/L) or >50,000 cells/mm3 with bone marrow involvement
c. Hemoglobin >8.0 g/dL
8. Adequate hepatic and renal function at screening defined as:
a. Serum AST and ALT =2.5 x ULN if no demonstrable liver involvement or =3 x ULN in the presence of liver
metastases
b. Bilirubin =1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin)
c. Serum creatinine =1.5 times ULN and creatinine clearance >30 mL/min (measured or calculated by Cockcroft and Gault equation [(140-Age) • Mass (kg)/(72 • creatinine mg/dL) • multiply by 0.85 if female])
9. PT/INR <1.5 x ULN and aPTT <1.5 x ULN.

Exclusion Criteria

1. History of prior malignancy except for the following:
a) Malignancy treated with curative intent and with no evidence of active disease present for more than 2 years before screening and felt to be at low risk for recurrence by treating physician.
b) Adequately treated lentigo maligna melanoma without current evidence of disease or adequately controlled nonmelanomatous skin cancer.
c) Adequately treated carcinoma in situ without current evidence of disease.
2. As judged by the Investigator, any evidence of severe or uncontrolled systemic disease, or current unstable or uncompensated respiratory or cardiac conditions, or uncontrolled hypertension, history of, or active, bleeding diatheses or uncontrolled active systemic fungal, bacterial, viral, or other infection, or intravenous anti-infective treatment within 2 weeks before first dose of study drug.
3. Diagnosis of PMBCL.
4. Known history of infection with HIV.
5. Serologic status reflecting active hepatitis B or C infection.
6. Active CMV infection
7. Undergone any of the following procedures or experienced any of the following conditions currently or in the preceding 6 months:
a) coronary artery bypass graft
b) angioplasty
c) vascular stent
d) myocardial infarction
e) angina pectoris
f) congestive heart failure (NYHA Grade =2)
g) ventricular arrhythmias requiring continuous therapy
h) supraventricular arrhythmias, including atrial fibrillation, which are uncontrolled
i) hemorrhagic or thrombotic stroke, including transient ischemic attacks or any other central nervous system
bleeding.
8. Current refractory nausea and vomiting, malabsorption syndrome, disease significantly affecting GI function, resection of the stomach, extensive small bowel resection that is likely to affect absorption, symptomatic inflammatory bowel disease, partial or complete bowel obstruction, or gastric restrictions and bariatric surgery, such as gastric bypass.
9. History of CNS lymphoma, leptomeningeal disease or spinal cord compression.
10. History of severe allergic or anaphylactic reactions to kinase inhibitors or history of hypersensitivity to active or inactive excipients of vistusertib or acalabrutinib or drugs with a similar chemical structure or class to vistusertib or acalabrutinib.
11. Presence of a GI ulcer diagnosed by endoscopy within 3 months before screening.
12. Uncontrolled Type 1 or Type 2 diabetes mellitus.
13. Any clinically significant pre-existing renal disease or high risk of developing renal impairment.
14. Major surgical procedure within 28 days before first dose of study drug. .
15. Unresolved toxicities from prior anticancer therapy, defined as having not resolved to CTCAE, Version 4.03 Grade 0 or 1, or to the levels dictated in the inclusion/exclusion criteria, with the exception of alopecia.
16. Any hematopoietic growth factors within 7 days of the first dose of study drug or pegylated G-CSF (pegfilgrastim) or darbepoetin within 14 days of the first dose of study drug.
17. Vaccinated with live, attenuated
