研究概览
简要总结
The purpose of this research study is to see if loncastuximab tesirine has any benefits at dose levels researchers found acceptable in earlier studies in patients with related forms of immune cell cancers. The researchers want to find out the effects (good and bad) that loncastuximab tesirine has on the participant and the participant's condition.

Subjects with H. pylori-positive gastric extranodal MZL who received an initial treatment with currently accepted antibiotics may be considered eligible if, after antibiotic regimen, subject has histologically confirmed MZL and was subsequently treated with at least 1 line of systemic therapy.

At least one of these lesions needs be histologically confirmed as MZL.

Subjects with splenic MZL who do not have a tumor to biopsy or an archival tumor tissue sample are eligible for participation provided subject is willing to undergo a bone marrow biopsy or provide an archival bone marrow biopsy that was obtained before the date of the first dose of study treatment; bone marrow sample must show histologically confirmed infiltration of MZL.
