Brief Summary
Part A of this study evaluates iopofosine I 131 (CLR 131) in patients with select B-cell malignancies (multiple myeloma( MM), indolent chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL), lymphoplasmacytic lymphoma (LPL)/Waldenstrom Macroglobulinemia (WM), marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), diffuse large B-cell lymphoma (DLBCL), and central nervous system lymphoma (CNSL) who have been previously treated with standard therapy for their underlying malignancy. Part B (CLOVER-WaM) is a pivotal efficacy study evaluating IV administration of iopofosine I 131 in patients with WM that have received at least two prior lines of therapy.

Eligibility Criteria
You may qualify if:
- Histologically or cytologically confirmed MM; Patients with primary or secondary CNSL may be enrolled.
- ECOG performance status of 0 to 2
- years of age or older
- Life expectancy of at least 6 months
- Platelets ≥ 75,000/µL (if full-dose anticoagulation therapy is used, platelets ≥ 100,000/µL are required)
- WBC count ≥ 3000/µL
- Absolute neutrophil count ≥ 1500/µL
- Hemoglobin ≥ 9 g/dL (last transfusion, if any, must be at least 1 week prior to study registration, and no transfusions are allowed between registration and dosing)
- Estimated glomerular filtration rate ≥ 30 mL/min/1.73 m2
- Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) ≤ 2.5 × upper limit of normal (ULN)
- Bilirubin \< 1.5 × ULN
- International normalized ratio (INR) \< 2.5
- If patient is on full-dose anticoagulation therapy, the anticoagulation therapy must be reversible and reversal of the anticoagulation therapy must not be life-threatening, as judged by the Investigator
- Patients who have undergone stem cell transplant must be at least 100 days from transplant
- Patients with Multiple Myeloma
- +29 more criteria
You may not qualify if:
- Ongoing Grade 2 or greater toxicities due to previous therapies. Stable, tolerable Grade 2 AEs (eg, neuropathy) may be allowed.
- Prior external-beam RT resulting in greater than 20% of total bone marrow receiving greater than 20 Gy.
- Prior total body or hemi-body irradiation. Patients who have received prior low-dose total body or hemi-body irradiation may be allowed on a case-by-case basis after discussion with Sponsor (considerations may include factors such as time since irradiation, total lifetime accumulated dose, etc.)
- Extradural tumor in contact with the spinal cord or tumor located where swelling in response to therapy may impinge upon the spinal cord
- For patients with CLL/SLL, LPL, or MZL, transformation to a more aggressive form of NHL
- Ongoing chronic immunosuppressive therapy
- Clinically significant bleeding event within prior 6 months
- Ongoing anti-platelet therapy (except low-dose aspirin \[eg, 81 mg daily\] for cardioprotection)
- Anti-cancer therapy within two weeks of initial iopofosine I 131 infusion. Low dose dexamethasone for symptom management is allowed
- Radiation therapy, chemotherapy, immunotherapy, or investigational therapy within 2 weeks of eligibility-defining bone marrow biopsy.
- For patients with primary or secondary CNSL, active bleeding in the tumor bed and/or uncontrolled seizure activity
- Histologically or cytologically confirmed WM. Patients with a diagnosis of LPL may be enrolled with prior Sponsor approval.
- Patient has an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 to 2 (Appendix C)
- Patient is 18 years of age or older
- Life expectancy of at least 6 months
- +8 more criteria
