Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Provided signed written informed consent prior to initiation of any study-related procedures;
  2. Males and females ≥ 18years of age at the time of consent are obtained (or meet the country's regulatory defined adult legal age);
  3. Tumor type criteria:

    1. Relapsed/refractory histologically documented non-Hodgkin's lymphoma (NHL) must have received at least 2 prior systemic therapies and should meet the following criteria:

      • Follicular lymphoma (FL) must meet criteria requiring systemic treatment per the GELF criteria and there is no standard salvage regimen available;
      • Diffuse large B-cell lymphoma NOS (2016 WHO classification of lymphoma neoplasms) relapsed or refractory with at least 2 prior regimen (e.g., rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone [R-CHOP]) and not a candidate for standard salvage regimens or autologous or allogeneic stem cell transplant.

      Patients without treatment options available known to provide clinical benefit are also eligible.

    2. Solid tumors that meet the following criteria: histologically or cytologically documented advanced recurrent or metastatic solid tumor. Measurable disease by RECIST v1.1 in at least 1 site; disease progression with the last line of therapy and at least one prior standard of care regimens, or tumor for which there is no approved therapy, or for which standard therapy is unsuitable or refused. Patients must have disease not amenable to surgery, radiation, or combined modality therapy with curative intent. Patients without treatment options available known to provide clinical benefit are also eligible.
  4. Eastern Cooperative Oncology Group (ECOG) performance status ≤1;
  5. Predicted life expectancy of ≥ 3 months;
  6. Patient must meet the following laboratory values:

    1. Serum total Bilirubin ≤ 1.5 x ULN or 3.0 mg/dL for patients with Gilbert's syndrome
    2. AST/SGOT and ALT/SGPT ≤ 2.5 x ULN or ≤ 5 x ULN if liver metastases are present
    3. 24-hour creatinine clearance (calculated* or measured value**)≥ 50 mL/min

      *For calculated creatinine clearance (Ccr) value, the eligibility should be determined using the Cockcroft-Gault formula:

      1. Male Ccr (mL/mim) = body weight (kg) x (140-age)/[72 x creatinine (mg/dL)]
      2. Female Ccr (mL/min) = male Ccr x 0.85 ** A measured value Ccr value (i.e. not calculated) should meet this criterion.
    4. Platelets ≥ 100 x 109/L (no Platelet transfusion for 7 days prior to screening)
    5. Hemoglobin (Hgb) ≥ 9 g/dL (no RBC transfusion for 7 days prior to screening)

Exclusion Criteria:

  1. Any cancer-directed therapy (chemotherapy, antibody therapy, radiotherapy, hormonal therapy, biologic or immunotherapy, etc.) within 28 days;
  2. Symptomatic CNS metastases that are neurologically unstable or requiring increasing doses of steroids to control CNS disease. Note: Any major surgery, radiotherapy or immunotherapy within the 4 weeks prior to first dose of study drug, or palliative radiotherapy to a single symptomatic lesion within the 2 weeks prior to first dose of study drugs;

However, patients that can be controlled with treatment are eligible;
  7. Concomitant malignancies or previous malignancies with less than 2 years of disease-free interval at the time of enrollment (but basal cell carcinoma skin cancer, cervical CIS (carcinoma in situ), CIS of the breast, localized or low Gleason grade prostate cancer, and < T2 bladder cancer can be included);
  8. Concurrent use of therapeutic warfarin is allowed. However, anticoagulants that do not have reversal agents available are prohibited except low molecular weight heparin and direct oral anticoagulants (see Section 6.4).

    4. Myocardial infarction, severe/unstable angina, symptomatic congestive heart failure (Class III or IV heart failure as defined by the New York Heart Association (NYHA) functional classification system, see Appendix 14.5) within the previous 3 months; if > 3 months, cardiac function must be within normal limits and the patient must be free of cardiac-related symptoms.
  14. Any evidence of serious active infections requiring antibiotics;
