Eligibility
Key inclusion criteria
1. Age = 18 years on the day of signing informed consent.

2. Based on pathology review at the local institution, using the most recent edition of
the World Health Organization (WHO) Classification of Tumors of Hematopoietic and
Lymphoid Tissues as guidance, leading to the diagnosis of one of the following
diseases and their histological subtypes: PTCL, CTCL, and B-cell NHL.

3. Patients must have relapsed or refractory disease after at least one prior systemic
anti-tumor treatment.

4. The patients enrolled in Phase II of the study should have received NOT more than five
lines of prior systemic therapies.

5. Patients must have at least one evaluable lesion per Lugano 2014 Criteria. Measurable
lesions are defined as those that can be accurately measured in at least two
dimensions with conventional techniques (positron emission tomography/Computed
tomography [PET/CT], magnetic resonance imaging [MRI]) or as > 1.5 cm with spiral CT
scan. Patients with non-measurable lesions but assessable diseases (e.g., marrow
disease without other radiographically measurable diseases) may be enrolled on a
case-by-case basis in discussion with the Sponsor.

6. ECOG performance status 0 to 2.

7. At least 3 months of expected survival.

8. Adequate organ functions, further defined as:

- Hemoglobin = 9 g/dL.

- Absolute neutrophil count (ANC) = 1 × 10E+09/L.

- Platelets = 50 × 10E+09/L (patient without bone marrow [BM] involvement) and = 30
× 10E+09/L (patient with BM involvement).

- Total bilirubin = 1.5 times the upper limit of normal (ULN).

- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 2.5 × ULN
if known liver involvement. The ALT and AST should be = 1.5 × ULN in absence of
liver involvement/metastasis.

- Serum creatinine = 2.0 mg/dL or calculated creatinine clearance = 50 mL/min (as
calculated by the Cockcroft-Gault method).

- Activated partial thromboplastin time (APTT) or international normalized ratio
(INR) = 1.5 × ULN (unless patient is receiving anticoagulants).

Key exclusion criteria
1. Received any anti-tumour treatment (i.e., chemotherapy, radiotherapy, immunotherapy,
biologic therapy, endocrine therapy, etc.,) within four weeks (or five half-lives of
the agent, whichever is shorter) prior to the first dose of study drugs, with the
following exceptions:

1. Palliative radiation therapy within 2 weeks.

2. Oral small molecule targeted therapies within 2 weeks prior to the first dose of
study drugs or within 5 half-lives of the drug, whichever is shorter.

3. Herbal medications within 7 days prior to the first dose.

2. Received other investigational agents (not yet approved by any regulatory agency)
within four weeks prior to the first dose of any study drugs.

3. Immunosuppressive medication > 10 mg prednisolone per day or equivalent within 14 days
prior to the first dose of the study drug. Note: Use of immunosuppressive medications
as prophylaxis in subjects with contrast allergies are acceptable. In addition,
temporary uses of corticosteroids considered non-clinically significant may be
approved on a case-by-case basis in discussion with the Sponsor.

4. Known clinically active central nervous system (CNS) or meningeal involvement. In the
absence of symptoms, investigation into CNS involvement is not required. Patients are
eligible if metastases have been treated, patients are neurologically returned to
baseline or neurologically stable for at least four weeks and not requiring steroid
therapy for at least one week prior to Cycle 1 Day 1.

5. Active infection and in current need of, or likely to need, intravenous (IV)
anti-infective therapy.

6. History of immunodeficiency, including history of any positive test result for human
immunodeficiency virus (HIV) antibody.

7. Patients who are known to be hepatitis B or C positive (positive HBsAg and/or
detectable level of HBV DNA or positive HCV antibody).

8. Active Epstein Barr virus (EBV) unrelated to underlying lymphoma (positive serology
for anti-EBV VCA IgM antibody and negative for anti-EBV EBNA IgG antibody, or clinical
manifestations and positive EBV polymerase chain reaction [PCR] consistent with active
EBV infection).

9. Active CMV (positive serology for anti-CMV IgM antibody, negative for anti-CMV IgG
antibody, and positive CMV PCR with clinical manifestations consistent with active CMV
infection) and requiring therapy.

10. Current history of a serious uncontrolled medical disorder, metabolic dysfunction,
physical examination findings, or clinical laboratory findings giving reasonable
suspicion of a disease or condition that contraindicates use of an investigational
drug or render the patient at high risk from treatment complications.
