   2. Platelet count: For patients with CLL ≥ 50,000/μL; For patients with lymphomas ≥ 75,000/μL without bone marrow involvement and ≥ 50,000/μL with bone marrow involvement. These thresholds should be qualified without platelet transfusion support.
   3. Hemoglobin ≥ 9 g/dL (RBC Transfusion is allowed to achieve this Hb)
   4. Total Bilirubin ≤ 1.5 x ULN; (Patients with known Gilbert's syndrome are allowed with a Total Bilirubin ≤ 2.5 x ULN)

   7. Creatinine clearance (CrCl) ≥ 60 mL/min (either measured or estimated by the Cockcroft-Gault formula). (Cockcroft-Gault formula for estimated creatinine clearance \[eCrCl\]: eCrCl = \[140- Age\] × Weight \[kg\] × \[0.85 if Female\] / \[72 × serum creatinine (mg/dL)\]).
4. Ability to swallow and retain oral medications
5. Histopathological diagnosis of Non-Hodgkin Lymphoma (NHL) or Chronic Lymphocytic Leukemia (CLL) or Hodgkin disease. Note:

5a. The lymphoma should be either in Stage III or IV according to Lugano classification (Cheson et al. 2014) at screening. 5b. The lymphomas included in this study must fall within one of the following 2017 World Health Organization categories except lymphoma mentioned in Exclusion criterion #5:

* Mature B-cell neoplasms (excluding plasma cell neoplasms, heavy chain disease, and primary central nervous system \[CNS\] lymphoma).
* Mature T- and NK-cell neoplasms.
* Hodgkin lymphomas 5c. The CLL should be Binet Stage C/Rai stage III or IV, as per the International Workshop on Chronic Lymphocytic Leukemia (iwCLL) guidelines (Hallek et al. 2018).

  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, or the subject is not eligible for HD-ASCT, or that the subject has refused HD-ASCT.

  7\. In the case of patients who have lymphoid malignancies for which CAR-T therapy is indicated, eligibility for this study requires that the disease has relapsed after CAR-T, or the patient is not eligible for CAR-T, or the patient has refused CAR-T, or the CAR-T is not available locally.

  8\. Evidence of measurable disease as per Lugano Criteria for Lymphoma (Cheson et al. 2014) or evidence of measurable disease as per iwCLL Criteria for CLL (Hallek et al. 2018). Note: Patients with Small Lymphocytic Lymphoma (SLL) alone or in combination with CLL are allowed.

  9\. Standard curative measures do not exist, and the patient must have exhausted all effective therapies available locally. The patients must have relapsed or refractory to at least 2 prior lines of systemic therapies for NHL or CLL, or Hodgkin disease.

Note:

* Any cancer patient with access to any effective therapy locally must not be enrolled.
* Patients with CLL should have documented evidence for progressive or symptomatic disease (active disease) and must have indications for treatment (Hallek et al 2018).
* Patients with indolent lymphomas also must have indications for treatment, such as the GELF (Brice et al 1997) or BNLI criterion (Ardeshna et al 2003)

Exclusion Criteria:

1. Systemic anti-cancer therapy, such as chemotherapy, biological therapy, or 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
2. Presence of an acute or chronic toxicity resulting from prior anticancer treatment, with the exception of alopecia or nail changes, that has not resolved to Grade ≤ 1, as determined by NCI CTCAE v 5.0. 1
3. Definitive Radiotherapy within the last 21 days of Cycle 1 Day 1 (limited field palliative radiation is allowed and no restrictions during the screening period or during the trial).
4. Use of any investigational agent within 28 days or 5 half-lives (whichever is longer) prior to Cycle 1 Day 1
5. Patients with Burkitt's lymphoma, Burkitt-like lymphoma, posttransplant lymphoproliferative disease, primary mediastinal large-B cell lymphoma, cutaneous lymphomas, mycosis fungoides (MF), or Sezary syndrome (SS).
6. 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.
7. Patients with lymphoma that requires immediate cytoreductive therapy.
8. Patients with low-grade lymphoma or indolent lymphoma that does not meet conventional criteria (Jeong SH, 2022) for requiring treatment.
9. Patients on drugs which are inhibitors of P-gp or BCRP or UGT1A1 and when these drugs cannot be discontinued from at least one week prior to Cycle 1 Day 1. Note: These drugs will be prohibited during Cycle 1 of therapy.
10. Major surgery ≤ 28 days from Cycle 1 Day 1 (major surgery is defined as a procedure requiring general anesthesia)
11. 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.
