We present an 88-year-old male with simultaneous T-cell prolymphocytic leukemia and stable smoldering myeloma with excellent initial response to three months of alemtuzumab. The patient relapsed at twelve months with severe cutaneous disease. Biopsy of a representative plaque demonstrated CD30 positivity in rare malignant lymphocytes. The patient demonstrated no response to reintroduction with a full course of alemtuzumab. He was therefore treated with brentuximab vedotin, resulting in partial remission of skin involvement that persisted for three months...

Hodgkin lymphoma is a unique disease entity characterized by a low number of neoplastic tumor cells surrounded by an inflammatory microenvironment composed of dysfunctional immune cells. Recent molecular and genetic studies have revealed that upregulation of the immune checkpoint pathway programmed death 1/programmed death ligand 1 is a key oncogenic driver of Hodgkin lymphoma. Corroborating these mechanistic studies, early-phase clinical trials using the checkpoint inhibitors nivolumab and pembrolizumab in treatment regimens for relapsed and/or refractory Hodgkin lymphoma have demonstrated impressive response rates, a promising durability of response, and a favorable side-effect profile...

High-dose chemotherapy with autologous stem cell transplantation remains the current standard of treatment for young patients with Hodgkin lymphoma in first relapse or in those who are refractory to first-line treatment. The most important prognostic factors in relapses are clinical stage IV, poor performance status, bulky mass, and less than partial remission after salvage chemotherapy. Standard salvage chemotherapy in relapse before autologous transplantation has not been defined; however, DHAP and ICE are most frequently used in this setting...

Marine natural products are served as attractive source of anticancer therapeutics, with the great success of "first-in-class" drugs, such as Yondelis, Halaven, and Brentuximab vendotin. Lagunamides A-C from marine cyanobacterium, Lyngbya majuscula, exhibit exquisite growth inhibitory activities against cancer cells. In this study, we have systematically investigated the structure-activity relationships (SAR) of a concise collection of lagunamide A and its analogs constructed by total chemical synthesis against a broad panel of cancer cells derived from various tissues or organs, including A549, HeLa, U2OS, HepG2, BEL-7404, BGC-823, HCT116, MCR-7, HL-60, and A375...

Hodgkin lymphoma (HL) is a highly curable hematologic malignancy, and ~70% of cases can be cured with combination chemotherapy with or without radiation. However, patients with primary resistant disease have a cure rate of <30%. For such patients, high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered to be the standard treatment. If patients fail to respond to ASCT or relapse soon thereafter, they usually receive another ASCT, allogeneic stem cell transplantation or treatment with novel agents...

Brentuximab vedotin (BV) significantly improved progression-free survival in a phase 3 study in patients with relapsed or refractory Hodgkin lymphoma (RR-HL) post-autologous-haematopoietic stem cell transplant (auto-HSCT); we report the impact of BV on quality of life (QOL) from this trial. The European Quality of Life five dimensions questionnaire was administered at the beginning of each cycle, end of treatment, and every 3 months during follow-up; index value scores were calculated using the time trade-off (TTO) method for UK-weighted value sets...

Evolution of cancer therapeutics has resulted in the development of agents with varying mechanisms of selective target inhibition. One such therapeutic approach is utilizing antibody-drug conjugates (ADCs), the combination of a cytotoxic agent linked with a monoclonal antibody, to achieve localization of the target and internalization of the cytotoxic agent in order to maximize efficacy with fewer toxicities. This review focuses on CD30 as a therapeutic target and the development and clinical activity of the ADC brentuximab vedotin in Hodgkin lymphoma (HL) and other B cell lymphomas...

The CD30 antigen is strongly expressed on neoplastic cells in classical Hodgkin lymphoma (HL), anaplastic large cell lymphoma (ALCL) and other hematologic malignancies (such as DLBCL and cutaneous TCL), while is almost undetectable on healthy tissues, representing an ideal immunotherapeutic target. Since unconjugated anti-CD30 antibody (SGN-30) demonstrated limited clinical activity, researchers' effort aimed to create an antibody-drug conjugate (ADC), leading to discovery of SGN-35 (brentuximab vedotin), in which an anti-CD30 antibody is linked to the antimitotic agent monomethyl auristatin E (MMAE)...

The goal of this study was to better understand the chromatographic conditions in which monoclonal antibodies (mAbs) of broad hydrophobicity scale and a cysteine conjugated antibody-drug conjugate (ADCs), namely brentuximab-vedotin, could denaturate. For this purpose, some experiments were carried out in HIC conditions using various organic modifier in natures and proportions, different mobile phase temperatures and also different pHs. Indeed, improper analytical conditions in hydrophobic interaction chromatography (HIC) may create reversed-phase (RP) like harsh conditions and therefore protein denaturation...

Hodgkin lymphoma (HL) is a lymphoid malignancy that is typically derived from germinal-center B cells. EBV infection, mutations in NF-κB pathway genes, and genetic susceptibility are known risk factors for developing HL. CD30 and NF-κB have been identified as potential biomarkers in pediatric HL patients, and these molecules may represent therapeutic targets. Although current risk adapted and response based treatment approaches yield overall survival rates of >95%, treatment of relapse or refractory patients remains challenging...

Despite the many advances in the treatment of hematological malignancies over the past decade, outcomes in refractory lymphomas remain poor. One potential strategy in this patient population is the specific targeting of IL-2R-α (CD25), which is over-expressed on many lymphoma and leukemic cells, using antibody drug conjugates (ADCs). ADCT-301 is an ADC composed of human IgG1 HuMax®-TAC against CD25, stochastically conjugated through a dipeptide cleavable linker to a pyrrolobenzodiazepine (PBD) dimer warhead with a drug-antibody ratio (DAR) of 2...

Anaplastic large cell lymphoma (ALCL) is an aggressive T-cell lymphoma characterized by strong and uniform expression of CD30. Brentuximab Vedotin (BV), an anti-CD30 antibody-drug conjugate has been approved by the U.S.FDA for relapsed/refractory systemic ALCL and achieves improved outcomes. We report a 44-year-old African-American man who presented with lymphadenopathy, lip, and chest nodules diagnosed as CD30+, ALK-negative ALCL. The patient was treated with BV upon recurrence. While on treatment, the patient developed new-onset nodules on the chest and back...

BACKGROUND: US Food and Drug Administration approval of brentuximab vedotin for treatment of CD30-positive relapsed/refractory lymphomas, including classical Hodgkin lymphoma and anaplastic large cell lymphoma, initiated significant interest in researching CD30 expression in other therapy-resistant or relapsed lymphomas. We evaluated CD30 expression in 116 cases of aggressive B-cell lymphomas diagnosed at Penn State Milton S. Hershey Medical Center between 2000 and 2012 with the purpose of assessing the benefit of treatment with brentuximab...

CD30 is a novel therapeutic target in human mast cell (MC) neoplasms. In this 'comparative oncology' study, we examined CD30 expression and regulation in neoplastic canine MC using a panel of immunomodulatory cytokines [interleukin-2 (IL-2), IL-4, IL-5, IL-6, IL-13 and stem cell factor (SCF)] and the canine mastocytoma cell lines NI-1 and C2. Of all cytokines tested IL-4 was found to downregulate expression of CD30 in NI-1 and C2 cells. We also found that the CD30-targeting antibody-conjugate brentuximab vedotin induces growth inhibition and apoptosis in both MC lines...

Despite the high first-line cure rates in patients with Hodgkin Lymphoma (HL) still 10%-20% of patients suffer from relapsed or refractory disease. High-dose chemotherapy (HDCT) followed by autologous stem cell transplant (ASCT) is standard of care for suitable patients with relapsed or refractory HL and allows for cure in approximately 50%. Due to the poor prognosis of high-risk patients even with HDCT and ASCT, consolidation strategies have been evaluated to improve the cure rates. For patients with recurrence after HDCT and ASCT, treatment is palliative in most cases...
