Arm && Interventions

Group	Intervention	Description
BP1002 monotherapy	L-Bcl-2 antisense oligonucleotide	L-Bcl-2 Antisense oligonucleotide (BP1002) is given in a sequential, dose escalation design. Starting dose is 20mg/m\^2.

Primary Outcome Measures

Name	Time	Method
Recommended Phase 2 dose (RP2D) of BP1002	210 days	Determine RP2D by evaluating Maximally Tolerated Dose (MTD) data: Any Dose Limiting Toxicity (DLT) observed will trigger an expansion of a cohort from 3 to 6 patients. A second DLT at any dose level will identify the Maximum Dose. The dose below that will be the MTD.
Determine plasma pharmacokinetics (PK) of BP1002 using maximum plasma drug concentration	30 days	Evaluate in vivo PK of BP1002 using maximum plasma drug concentration (Cmax)
Determine plasma pharmacokinetics (PK) of BP1002 using volume of distribution	30 days	Evaluate in vivo PK of BP1002 volume of distribution (Vd)
Determine half-life plasma pharmacokinetics (PK) of BP1002	30 days	Evaluate in vivo PK of BP1002 half-life (t1/2)
Identify Dose Limiting Toxicity (DLT) of BP1002	30 days	Identify DLT of BP1002 using non-hematologic and hematologic measures per NCI CTCAE criteria
Identify and grade treatment-emergent laboratory abnormalities of escalating doses of BP1002 by identification and grading of	30 days	Identify and grade treatment-emergent laboratory abnormalities of BP1002 using non-hematologic and hematologic measures per NCI CTCAE criteria
Identify conduction and rhythm changes (treatment emergent QTc elevations or other treatment emergent changes in EKG intervals) of escalating doses of BP1002	30 days	Collection of 12-lead EKGs at defined intervals to identify conduction and rhythm changes (treatment emergent QTc elevations or other treatment emergent changes in EKG intervals)
Determine plasma pharmacokinetics (PK) of BP1002 using elimination rate constant	30 days	Evaluate in vivo PK of BP1002 elimination rate constant
Identify and grade treatment-emergent adverse events (TEAE) of escalating doses of BP1002	30 days	Identify TEAE of BP1002 using non-hematologic and hematologic measures per NCI CTCAE criteria
Determine pharmacokinetics (PK) of BP1002	30 days	12-lead EKG assessments will be collected and analyzed for conduction and rhythm changes (treatment emergent QTc elevations or other treatment emergent changes in EKG intervals) from those the EKG obtained immediately before the first BP1002 dose, and after BP1002 dose, and will mirror the time points used to collect the plasma PK assessments

Secondary Outcome Measures

Name	Time	Method
Determine estimates for progression-free survival (PFS)	30 days	Measured from treatment start date to date of progression or death by CBC and/or bone marrow aspirate
Determine estimates for time to progression (TTP)	30 days	Measured from treatment start date to date of progression by CBC and/or bone marrow aspirate
Activity of BP1002 on Bcl-2 expression in tumor samples	30 days	Flow cytometric assays to determine the effects of BP1002 on Bcl-2 protein expression using patient blood samples
Determine evidence of tumor response by Complete Blood Count (CBC)	30 days	Assess tumor response by evaluating CBC measurements to determine complete response (CR), partial response (PR), or minor response (MR) using appropriate uniform response criteria as published by Response Evaluation Criteria in Lymphoma (RECIL) 2017, CLL guidelines, and International Workshop on Waldenström's Macroglobulinemia (IWWM 6th)
Determine evidence of tumor response by bone marrow aspirate	30 days	Assess tumor response by evaluating bone marrow aspirate to determine complete response (CR), partial response (PR), or minor response (MR) using appropriate uniform response criteria as published by Response Evaluation Criteria in Lymphoma (RECIL) 2017, CLL guidelines, and International Workshop on Waldenström's Macroglobulinemia (IWWM 6th)
