Purpose: This study was undertaken to evaluate the effects of MDX-1401, a nonfucosylated fully human monoclonal antibody that binds to human CD30, and to determine whether it exhibits greater in vitro and in vivo activity than its parental antibody. Experimental Design: Assaysmeasuring antibody binding to CD30-expressing cells and FcγRIIIa (CD16) transfectants as well as antibody-dependent cell...

CD40 is a member of the nerve growth factor receptor family, showing a significant homology to the Hodgkin's disease (HD)-associated antigen CD30 and is capable of transduce growth signals in a number of cell types. A series of 312 lymphoma samples, including 139 cases of HD, 32 cases of CD30+ anaplastic large cell (ALC) lymphomas, 141 cases of other non-Hodgkin's lymphomas (NHLs), and a panel ...

The spectrum of CD30+ lymphoproliferative diseases of the skin includes CD30+ cutaneous anaplastic large cell lymphoma, lymphomatoidpapulosis, as well as borderline cases. These entities constitute the second most common group of cutaneous lymphomas according to the newly revised World Health Organization and European Organisation for Research and Treatment of Cancer consensus classification. R...

Eosinophilic ulcer of the oral mucosa (EUOM) is a very rare, benign, self-limiting ulcerative lesion of the oral cavity of unknown pathogenesis, and belongs to the same spectrum of CD30(+) T-cell lymphoproliferative disease (LPD) of the oral mucosa. The etiology and pathogenesis of the disease are unknown. We report two cases in children who were initially diagnosed with EUOM and CD30(+) T-cell...

Today, most approved therapeutic antibodies are provided as immunoglobulin G (IgG), whereas small recombinant antibody formats are required for in vitro antibody generation and engineering during drug development. Particularly,single chain (sc) antibody fragments like scFv or scFab are well suited for phage display and bacterial expression, but some have been found to lose affinity during conve...

Brentuximab vedotin (SGN-35) is an antibody-drug conjugate (ADC) directed against the CD30 antigen expressed on Hodgkin lymphoma and anaplastic large cell lymphoma. SGN-35 consists of the cAC10 chimerized IgG1 monoclonal antibody SGN30, modified by the addition of a valine-citrulline dipeptide linker to permit attachment of the potent inhibitor of microtubule polymerization monomethylauristatin...

Successful immunotherapy of Hodgkin's disease is so far hampered by the striking unresponsiveness of lymphoma infiltrating immune cells. To mobilize both adoptive and innate immune cells for an anti-tumor attack we fused the pro-inflammatory cytokines IL2 and IL12 to an anti-CD30 scFv antibody in a dual cytokine fusion protein to accumulate both cytokines at the malignant CD30(+) Hodgkin/Reed-S...

Brentuximab vedotin (SGN-35) is an antibody-drug conjugate with a high selectivity against CD30⁺ cell lines and more than 300-fold less activity against antigen-negative cells. In the last years, the results of many in vitro and in vivo studies have led to the fast approval of this drug to treat lymphoma patients. Another innovative method to treat tumor cells including lymphoma cells is the us...

AIMS To determine the cellular origin of the most potent cytokine present in Hodgkin's disease, transforming growth factor (TGF) beta, the polycellular population of Hodgkin's tissue was studied using in situ hybridisation. METHODS A biotin labelled oligo-complementary DNA (cDNA) was constructed according to the previously determined sequence for TGF beta 1 cDNA. Forty three frozen and paraff...

Although the majority of patients with Hodgkin lymphoma attain a complete response with initial combination chemotherapy and/or radiotherapy, 20–40% of patients with newly diagnosed, advanced-stage Hodgkin lymphoma are refractory to initial therapy or relapse following a response.1,2 The optimal second-line treatment approach for these patients is high-dose chemotherapy followed by autologous s...
