Brief summary:
The primary objectives of this study are to determine the maximum tolerated dose (MTD) or optimal biologic dose (OBD) and safety profile of CAT-8015 in participants with relapsed or refractory advanced B-cell NHL (diffuse large B-cell lymphoma \[DLBCL\], follicular lymphoma \[FL\], mantle cell lymphoma \[MCL\]) or CLL.

Detailed description:
To determine the maximum tolerated dose (MTD) or optimal biologic dose (OBD) of CAT-8015 in participants with relapsed or refractory advanced B-cell NHL (DLBCL, FL, MCL) or CLL.

Arms:
arm 1: Participants will receive 20 mcg/kg Moxetumomab pasudotox (CAT-8015) as an intravenous (IV) infusion over 30 minutes on Days 1, 3, and 5 of every 28-day cycle. Dose escalation is to be continued to the Maximum tolerated dose (MTD) or Optimal biologic dose (OBD). Subsequent dose levels with a 10 mcg/kg increase from the previous dose level are possible if an MTD or OBD is not reached by 60 mcg/kg. arm 2: Participants will receive 30 mcg/kg Moxetumomab pasudotox (CAT-8015) as an intravenous (IV) infusion over 30 minutes on Days 1, 3, and 5 of every 28-day cycle. Dose escalation is to be continued to the Maximum tolerated dose (MTD) or Optimal biologic dose (OBD). Subsequent dose levels with a 10 mcg/kg increase from the previous dose level are possible if an MTD or OBD is not reached by 60 mcg/kg. arm 3: Participants will receive 40 mcg/kg Moxetumomab pasudotox (CAT-8015) as an intravenous (IV) infusion over 30 minutes on Days 1, 3, and 5 of every 28-day cycle. Dose escalation is to be continued to the Maximum tolerated dose (MTD) or Optimal biologic dose (OBD). Subsequent dose levels with a 10 mcg/kg increase from the previous dose level are possible if an MTD or OBD is not reached by 60 mcg/kg. arm 4: Participants will receive 50 mcg/kg Moxetumomab pasudotox (CAT-8015) as an intravenous (IV) infusion over 30 minutes on Days 1, 3, and 5 of every 28-day cycle. Dose escalation is to be continued to the Maximum tolerated dose (MTD) or Optimal biologic dose (OBD). Subsequent dose levels with a 10 mcg/kg increase from the previous dose level are possible if an MTD or OBD is not reached by 60 mcg/kg. arm 5: Participants will receive 60 mcg/kg Moxetumomab pasudotox (CAT-8015) as an intravenous (IV) infusion over 30 minutes on Days 1, 3, and 5 of every 28-day cycle. Dose escalation is to be continued to the Maximum tolerated dose (MTD) or Optimal biologic dose (OBD). Subsequent dose levels with a 10 mcg/kg increase from the previous dose level are possible if an MTD or OBD is not reached by 60 mcg/kg.

Interventions: intervention 1: CAT-8015 20 mcg/kg intervention 2: CAT-8015 30 mcg/kg intervention 3: CAT-8015 40 mcg/kg intervention 4: CAT-8015 50 mcg/kg intervention 5: CAT-8015 60 mcg/kg
