Ph I/II Study of Subcutaneously Administered Veltuzumab (hA20) in NHL and CLL
The purpose of this study is to determine if a subcutaneous (SC) dosing schedule of veltuzumab can be established in NHL or CLL patients and to confirm the safety and efficacy of veltuzumab that was previously established when administered intravenously.
|Condition or Disease||Intervention/Treatment||Phase|
||Phase 1/Phase 2|
The first study of veltuzumab given IV weekly in NHL patients (IM-T-hA20-01) has shown excellent tolerability and even efficacy at weekly intravenous doses as low as 80-120 mg/m2 over 4 consecutive weeks. These clinical results confirm experiments laboratory studies. Laboratory studies using Veltuzumab administered subcutaneously showed potent activity based on B-cell depletion. The current study's goal is to determine if a subcutaneous (SC) dosing schedule of veltuzumab can be established in patients with NHL or CLL
Arms and Interventions
veltuzumab is a humanized CD20 antibody administered subcutaneously in this study.
veltuzumab (hA20) will be studied at different dose levels, administered subcutaneously once a week for 4 weeks.
Primary Outcome Measures
- Safety/tolerability [over 2 years after treatment]
safety will be assessed by monitoring lab results and adverse events, which will be assessed every 3 months for up to 2 years.
Histologically confirmed diagnosis of CD20 positive chronic lymphocytic leukemia (CLL)
Either previously untreated or relapsed
Measurable disease (at least one lesion > 1.5 cm for NHL, or ALC > 5,000 for CLL) see full protocol for additional criteria
Previously untreated NHL patients with Stage I and II disease (Ann Arbor classification)
Previously untreated CLL patients with Stage 0-2 disease (Rai classification) unless specific treatment indications by NCCN guidelines exist (symptomatic, recurrent infections, end-organ function, cytopenias and steady disease progression).
