6. In the case of subjects who have lymphoma for which high-dose chemotherapy and autologous stem cell transplantation (HDASCT) is considered a standard curative therapy, eligibility for this study requires that the subject's disease has relapsed after HDASCT, that the subject is not eligible for HD-ASCT, or that the subject has refused HD-ASCT.
7. In the case of subjects who have lymphoma for which CAR-T therapy is considered a standard therapy, eligibility for this study requires that the subjects disease has relapsed after CAR-T, or that the subject has refused CAR-T, or that the CAR-T therapy is not accessible to the patient.
8. Evidence of measurable disease as per Lugano Criteria for Lymphoma (Cheson BD et al, 2014).
9. Standard curative measures do not exist, and patient must have exhausted all effective therapies, available locally.
1. At a minimum, the patients must have received at least 2 prior lines of systemic therapies. These systemic therapies could be either in the stage II, III or IV.
2. Any cancer patient with access to any effective therapy must not be enrolled.
Exclusion Criteria:
1. Systemic anti-cancer therapy, such as chemotherapy, or biological therapy, immunomodulatory drug therapy, received within the past 28 days or 5 half-lives, whichever is longer, from the Cycle 1 Day 1 of the study.
Note: Concomitant use of low dose prednisone (up to 10 mg/day) is allowed.

5. Patients with cutaneous lymphomas, mycosis fungoides (MF) or Sézary syndrome (SS).
6. Primary CNS lymphoma
7. Known symptomatic or untreated or recently treated (≤ 6 months of screening) central nervous system (CNS) lymphoma. Patients with previously treated (\> 6 months of screening) CNS lymphoma and are now stable and asymptomatic, from CNS perspective, are allowed
8. Patients with lymphoma that requires immediate cytoreductive therapy
9. Patients with lymphoma that requires immediate cytoreductive therapy
10. Patients on the drugs which are sensitive substrates of CYP2C8 and cannot be discontinued at least one week prior to Cycle 1 Day 1
11. Patients on the drugs which are sensitive substrates of either Poglycoprotein (P-gp) or breast cancer resistance protein (BCRP) and cannot be discontinued at least one week prior to Cycle 1 Day 1
12. Major surgery ≤ 28 days from Cycle 1 Day 1 (major surgery is defined as a procedure requiring general anesthesia)
13. Active infection requiring systemic therapy. Note: Prophylactic use of antibiotics is allowed. Any infection detected during screening period which is resolved adequately according to investigator before the Cycle 1 Day 1, is allowed.
14. Known to be human immunodeficiency virus (HIV) positive or have an acquired immunodeficiency syndrome-related illness
15. Known active or chronic hepatitis B (HbsAg +ve) or hepatitis C infection (HCV antibody +ve)
16. The patient who is expected to require any other form of antineoplastic therapy or targeted therapy while on study.
17. Uncontrolled congestive heart failure (New York Heart Association (NYHA) Class 2-4), angina, myocardial infarction, cerebrovascular accident, coronary/peripheral artery bypass graft surgery, or transient ischemic attack, or pulmonary embolism within 3 months prior to Cycle 1 Day 1
18. Ongoing cardiac dysrhythmias requiring treatment of any grade or treatment of cardiac dysrhythmias in past 3 months, before Cycle 1 Day 1.
19. QTc (Bazzett) interval \>460 ms on ECG at screening and/or at Cycle 1 Day 1 pre-dose.
20. Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, active peptic ulcer disease or significant gastritis, active bleeding diatheses, presence of any major medical illness (e.g. renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, or psychiatric illness/social situations or clinically significant laboratory / ECG abnormalities at screening, any or a combination of illnesses, which, in the opinion of the PI, may either put the patient at risk because of participation in the study, or influence the results or the patient's ability to participate in the study
