For the treatment of Hodgkin lymphoma, bispecific monoclonal antibodies (bi-mAbs) were established which recognize the Hodgkin-associated CD30 antigen with one arm and the CD3 or CD28 antigen on T lymphocytes or the CD16 antigen on natural killer (NK) cells with the second arm. The NK cell-activating alpha-CD16/CD30 antibody was able to retarget human NK cells toward CD30- target cells and induce their lysis. Sixty percent of Hodgkin tumor-bearing severe combined immunodeficient mice responded to a combined treatment with bi-mAb and human NK cells, leading to a final cure rate of 20%. T cell-activating bi-mAbs were more effective, resulting in the cure of all mice treated. The in vivo administration of both alpha-CD3/CD30 and alpha-CD28/CD30 antibodies resulted in the specific activation of resting human T cells infiltrating the CD30+ Hodgkin tumors. Tumor-infiltrating lymphocytes in the group of mice treated with both T cell-activating bi-mAbs expressed high levels of cytokines and cytotoxic molecules such as perforin and the cytotoxic serine esterases granzyme A and B. More importantly, activated T cells did not home to CD30 tissue and did not enter the circulation. Encouraged by these preclinical data, 15 patients with treatment-refractory Hodgkin lymphoma were included in a phase I/II dose-escalation study and treated four times every 3 or 4 days with increasing doses of the alpha-CD16/CD30 bi-mAb ranging from 1 mg/m2 to 128 mg/m2. No dose-limiting toxicity occurred even at the highest doses. Of these 15 patients, one had a complete response, one a partial response, three a mixed response, two stable disease, and eight patients had progressive disease. Treatment with immunological effector cell-recruiting bi-mAbs is a promising new approach to the treatment of Hodgkin disease refractory to standard therapy.

Anaplastic large cell lymphoma (ALCL) represents approximately 2% of all non-Hodgkin lymphomas according to the recent Non-Hodgkin Lymphoma Classification Project. As defined in the revised European-American classification of lymphoid neoplasms (REAL), ALCL is a neoplasm of T-cell or null-cell lineage; 20% to 60% of cases are associated with the t(2;5)(p23;q35) translocation. ALCL commonly involves nodal as well as a wide variety of extranodal sites, although primary or secondary involvement of bone is rare. We describe the case of a 71-year-old man with stage IE T-cell ALCL, monomorphic variant, arising in the left anterior fifth rib and involving adjacent soft tissue without other sites of disease. The monomorphic histologic features hindered the initial recognition of this neoplasm as ALCL. However, strong uniform CD30 antigen expression and subsequent demonstration of the t(2;5)(p23;q35) translocation and anaplastic lymphoma kinase (ALK) immunoreactivity led to the correct diagnosis. We identified only 5 reported cases of T-cell and null-cell ALCL arising in bone and only 2 of these cases involved a single bone site. All 5 previously reported cases were ALCL of the classic type. We report a case of ALCL that is unique to our knowledge. This case of monomorphic ALCL was localized to bone and tumor cells contained the t(2;5)(p23;q35) translocation.

One of the most peculiar immunohistological characteristics of the tumour cells of Hodgkin's lymphoma, anaplastic large cell lymphoma (ALCL), and embryonal carcinoma of the testis is the expression of the CD30 antigen. Physiologically, CD30 expression is restricted to a few activated lymphocytes in normal lymphoid tissue and a small population of decidual cells. To clarify the reasons behind this highly restricted expression pattern and to learn about the combination of transcription factors involved in this regulation in Hodgkin's lymphoma and other CD30(+) malignancies, the 5'-flanking regulatory region of the cd30 gene was analysed. The major transcription start site was determined to be 270 bases upstream of the translational start codon in the Hodgkin's lymphoma-derived cell lines L591 and L428. Reporter gene assays revealed that the CD30 promoter (-413 to 84) induces a 50- to 1000-fold higher luciferase expression in CD30(+) human lymphoid cell lines (Co, Jurkat, and the Hodgkin's lymphoma-derived cell line L540) than in CD30(-) human lymphoid cell lines (DG75, SUP-T1, and U698M), CD30(-) human carcinoma cell lines (HeLa and MCF-7), or COS1 cells. Deletion analysis defined a TATA-less, minimal promoter sequence from -164 to 84. The transcription factor Sp1 and members of the Ets family induce CD30 expression, whereas the transcription factor Sp3 diminishes its induction. These data suggest that a high Sp1/Sp3 expression ratio and a peculiar expression pattern of the Ets transcription factors are involved in the overexpression of CD30 and might contribute to the transformation of CD30(+) tumour cells.

In recent years, substantial experience has been accumulated with tumor-specific immunotherapeutics which seem to be effective against minimal residual disease. The coupling of toxins to monoclonal antibodies has indicated promising results in early clinical trials. Recombinant DNA technology makes it possible to genetically fuse coding regions of V genes or cytokines to modified toxin domains. These recombinant immunotoxins can easily be manipulated to increase the cytotoxic potency or affinity. Binding single-chain variable fragments (scFv) expressed as chimeric fusion proteins on the surface of filamentous bacteriophages were selected on Hodgkin-derived cell lines. This technique was also used to create a new humanized anti-CD30 scFv which exhibits similar binding to the CD30 antigen when compared to its murine predecessor. ScFvs were then inserted into a new bacterial expression vector and thus fused to a deletion mutant of Pseudomonas exotoxin. Anti-CD25(scFv)-ETA' and anti-CD30(scFv)-ETA' were isolated from E. coli periplasm and purified by metal chelate affinity and size exclusion chromatography. All immunotoxins produced showed specific cytotoxicity against Hodgkin lymphoma cell lines as documented by competitive assays. In addition, these constructs were highly efficient in the treatment of disseminated human Hodgkin's disease in SCID mice. These in vivo data indicate a possible clinical impact for patients with relapsed CD25- and/or CD30-positive lymphoma.

Anaplastic large cell lymphoma (ALCL) represents a generally recognized group of large cell lymphomas. Defining features consist of a proliferation of predominantly large lymphoid cells with strong expression of the cytokine receptor CD30 and a characteristic growth pattern. With the use of molecular and clinical criteria, 3 entities of ALCL have been identified: primary systemic anaplastic lymphoma kinase (ALK)(+) ALCL, primary systemic ALK(-) ALCL, and primary cutaneous ALCL. ALK expression is caused by chromosomal translocations, most commonly t(2;5). ALK(+) ALCL predominantly affects young male patients and, if treated with chemotherapy, has a favorable prognosis. It shows a broad morphologic spectrum, with the "common type," the small cell variant, and the lymphohistiocytic variant being most commonly observed. The knowledge of the existence of these variants is essential in establishing a correct diagnosis. ALK(-) ALCL occurs in older patients, affecting both genders equally and having an unfavorable prognosis. The morphology and the immunophenotype of primary cutaneous ALCL show an overlap with that of lymphomatoid papulosis. Both diseases have an excellent prognosis, and secondary systemic dissemination is only rarely observed. The described ALCL entities usually derive from cytotoxic T cells. In contrast, large B-cell lymphomas with anaplastic morphology are believed to represent not a separate entity but a morphologic variant of diffuse large B-cell lymphoma. Malignant lymphomas with morphologic features of both Hodgkin disease and ALCL have formerly been classified as Hodgkin-like ALCL. Recent immunohistologic studies, however, suggest that ALCLs Hodgkin-like represent either cases of tumor cell-rich classic Hodgkin disease or (less commonly) ALK(+) ALCL or ALK(-) ALCL.

One of the major characteristics of anaplastic large cell lymphomas (ALCL) is the expression of the Ki-1/CD30 antigen. While the receptor mediates NF-kappaB-activation in Hodgkin's lymphomas, some data suggest the CD30-mediated apoptosis of other CD30-expressing cells. We were able to demonstrate that activation of CD30 leads to different effects regarding cell proliferation of the ALCL-derived cell lines Karpas 299 and JB6. Western and Northern blotting analysis revealed that CD30-induced growth inhibition of Karpas 299 cells correlated with a strong upregulation of the cell cycle inhibitor p21(CIP1/WAF1). We found a non activating point mutation at codon 273 in exon 8 of the p53 gene in Karpas 299 cells which indicates an p53-independent mechanism for induced p21 expression. Abundant p21 protein expression resulted in hypophosphorylation of the retinoblastoma protein (Rb) and inhibition of the proliferating cell nuclear antigen (PCNA). CD30-stimulated cells showed no indications of apoptotic cell death, like genomic DNA fragmentation or cleavage of the caspase-3 target protein poly (ADP-ribose) polymerase (PARP). Our results indicate that CD30 is able to mediate an p21-associated cell cycle arrest in ALCL with possible implications for prognosis and clinical treatment.

The CD30 antigen is a member of the tumor necrosis factor receptor (TNFR) family which is overexpressed on the surface of the tumor cells of Hodgkin's lymphoma, anaplastic large cell lymphoma (ALCL), and embryonal carcinoma of the testis. In this study the entire cd30 gene which is more than 24000 bp long and organized in eight exons was characterized by analyzing cosmid and phage lambda clones from human placental libraries with long-range polymerase chain reaction (PCR) and sequencing. Differences to other genes of the TNFR family were detected in the region encoding the extracellular domain of the cd30 gene. In nearly all other TNFR genes, the coding region of each cysteine-rich repeat is interrupted by one intron, i.e., the 3-4 cysteine-rich repeats of these receptors are encoded by at least 4-5 exons, whereas the six cysteine-rich repeats of the cd30 gene are encoded by two exons, i.e., each of these exons encode three cysteine-rich repeats. In addition, we also found a genetic polymorphism of tetranucleotide ATCC-repeats in the 5' part of the CD30 promoter. This region was amplified by PCR from seven CD30 overexpressing human lymphoid cell lines and five human tissues with an absent or very low CD30 expression. The amplification products showed length differences of more than 550 bp. The number of the ATCC-repeats was higher in CD30(+) cell lines than in normal tissues. Comparison of the individual PCR products in reporter gene assays revealed that the CD30 promoter activity increased with the length of this polymorphic region up to eightfold. The data suggest that the number of ATCC-repeats in the 5' region of the CD30 promoter modulates the regulation of CD30 expression.

CD30 (Ki-1) antigen has been considered to be expressed on hematopoietic cells including the ones of the recently described anaplastic large cell lymphoma (ALCL), the Reed-Sternberg (RS) cells of Hodgkin's disease and the scattered large parafollicular cells in normal lymphoid tissues. Since then, several reports have been published describing CD30 expression in non-hematopoietic and malignant cells, such as cultivated human macrophages, human decidual cells, histiocytic neoplastic cells, mesothelioma cells, embryonal carcinoma, and seminoma cells. In the present study, we investigated the immunohistochemical expression of CD30 antigen in 15 paraffin-embedded placentas from fetuses after spontaneous abortion in the first trimester of gestation (8th, 10th, and 12th week, respectively) using the monoclonal antibody Ber-H2. All the pregnant patients had been given hormonal medication to support gestation. In addition, a panel of monoclonal antibodies for the identification of leukocytes (CD45/LCA), B-lymphocytes (CD20/L-26), and T-lymphocytes (CD45RO/UCHLI) was performed. Our findings were correlated with those found in 15 placentas obtained from 15 fetuses at the same time, after therapeutic or voluntary abortions. This study demonstrates that, 1) decidual endometrial stromal cells are able to express the CD30 (Ki-1) antigen, 2) the expression of CD30 in decidual cells is higher in cases of hormonal administration (to support gestation), than that found in normal gestation. In the former cases (hormonal support of gestation), a mild mononuclear infiltration of the decidua by UCHLI (T marker) positive cells, accompanies the CD30 positive cells.

Ki-l positive anaplastic large cell non-Hodgkin's lymphomas are a recently recognized entity, unusual and characterized by the expression of CD30 antigen. The most usual clinical feature is peripheral lymphadenopathy with mediastinal sparing and extranodal disease which occurs in approximately half of the cases, with the skin as the most common site; lung, bone marrow and central nervous system involvement are uncommon. Therefore primary pulmonary Ki-l positive anaplastic large cell non-Hodgkin's lymphomas are an uncommon clinical entity. Their classification and clinical behaviour look like high grade malignancy lymphomas, that in the most cases are presented in advanced stages disease to the diagnostic. They are presented with higher incidence in young people, where prognostic is more favourable. Clinical, morphologic and inmunophenotypic features of this lymphoma type are reported.

Ki-4.dgA is an anti-CD30 immunotoxin (IT) constructed by coupling the monoclonal antibody Ki-4 via a sterically hindered disulfide linker to deglycosylated ricin A-chain. This IT was efficacious in vitro and in SCID mice with disseminated human Hodgkin's lymphoma. Accordingly, a Phase I trial in patients (pts) with Hodgkin's lymphoma was designed. The objectives of this Phase I trial were to determine the maximum tolerated dose, the dose-limiting toxicities, pharmacokinetics, and antitumor activity. Seventeen pts with relapsed CD30+ lymphoma were treated with escalating doses (5, 7.5, or 10 mg/m(2)/cycle) of the IT as four bolus infusions on days 1, 3, 5, and 7 for one to three cycles. All of the pts had progressive disease and were heavily pretreated. Nine had primary progressive disease and 14 had advanced disease with massive tumor burdens. The mean age was 35 years (24-52 years). Peak serum concentrations of the intact IT varied from 0.23 to 1.1 microg/ml. Side effects and dose-limiting toxicities were related to vascular leak syndrome, i.e., decreases in serum albumin, edema, weight gain, hypotension, tachycardia, myalgia, and weakness. The maximum tolerated dose was 5 mg/m(2). Seven of 17 (40%) pts made human antiricin antibodies (> or =1.0 microg/ml), and 1 pt developed human antimouse antibodies (> or =1.0 microg/ml). Clinical response in the 15 evaluable pts included 1 partial remission, 1 minor response, and 2 stable diseases. In conclusion, the IT was less well tolerated than other ITs of this type. This might be because of the low number of CD30+ peripheral blood mononuclear cells, and in part because of binding of the IT to soluble CD30 antigen and the resulting circulation of IT/sCD30 complexes.
