About

This is a phase I study of BTK inhibitor CT-1530 in patients with relapsed or refractory B cell non-Hodgkin lymphoma (B-NHL), chronic lymphocytic leukemia (CLL) or Waldenstrom's macroglobulinemia (WM).

The purpose of the study is to determine the MTD/RP2D of CT-1530, and evaluate its safety and tolerability as monotherapy in subjects with relapsed or refractory B cell non-Hodgkin lymphoma (B-NHL), chronic lymphocytic leukemia (CLL) or Waldenstrom's macroglobulinemia (WM).

Enrollment: 200 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Confirmed diagnosis of B cell Non-Hodgkin Lymphoma(according to World Health Organization [WHO] classification)including Chronic Lymphocytic Leukemia/Small cell Lymphocytic Leukemia (International Workshop),or Waldenstrom's Macroglobulinemia(Second International Workshop).
• Have failed ≥1 previous treatment for B-NHL/CLL/WM, and have relapsed or refractory disease following last prior treatment.
• Eastern Cooperative Oncology Group performance status of ≤ 1 and a life expectancy of at least 3 months.
• Measurable disease as per RECIST v1.1
• Availability of tumor sample
• Adequate hematologic function, as defined by neutrophils ≥ 1.0 x 10^9/L and platelets ≥ 50 x 10^9/L; patients with neutrophils < 1.0 x 10^9/L due to marrow infiltration are allowed to receive growth factors to bring pre-treatment neutrophils to ≥ 1.0 x 10^9/L.
• Adequate renal function, as defined by creatinine clearance of ≥ 50 ml/min (as estimated by the Cockcroft-Gault equation or as measured by nuclear medicine scan or 24 hour urine collection).
• Adequate liver function, as defined by AST and ALT ≤ 3 x ULN, and bilirubin ≤ 1.5 x ULN (unless documented Gilbert's syndrome).

Exclusion criteria

• Prior allogeneic bone marrow transplant
• Autologous stem cell transplant within 3 months of screening
• Active central nervous system involvement
• Subjects with autoimmune hemolytic anemia or immune thrombocytopenia
• Prior treatment with a Btk inhibitor
• Active uncontrolled infection
• History of malabsorption
• Uncontrolled illness, i.e cardiac, endocrine, respiratory, etc.

• History of another currently active cancer
• History of major surgery within 4 weeks or minor surgery within 1 week
• Other medical or psychiatric illness or organ dysfunction
• HIV positive
