This clinical trial is studying lymphoma. Lymphoma is a cancer that starts in the blood cells that fight infection. There are several types of lymphoma. This study will enroll people who have classical Hodgkin lymphoma (cHL), peripheral T cell lymphoma (PTCL), or diffuse large B cell lymphoma (DLBCL).
This clinical trial uses a drug called SGN-35C . The study drug is in testing and has not been approved for sale. This is the first time SGN -35C will be used in people.
This study will test the safety of SGN-35C in participants with lymphoma. It will also study the side effects of this drug. A side effect is anything a drug does to the body besides treating the disease.
This study will have three parts. Parts A and B of the study will find out the best dose and dosing schedule for SGN-35C. Part C will use the dose found in parts A and B to find out how safe SGN-35C is and if it works to treat select lymphomas.

DNA topoisomerase I (topo I) is the molecular target of the camptothecin group of anticancer drugs. These drugs are S-phase specific and require elevated topo I for tumor cell killing. To determine whether increased topo I expression occurs in testicular seminomas, 20 cases of testicular seminoma were retrieved from the surgical pathology files at the University of Utah Health Sciences Center and stained with an antibody that recognizes topo I in paraffin embedded human tissue sections. Topo I elevation was observed in 30% (6/20) of the seminomas. Because the response to topo I targeted drugs requires cell proliferation, the proliferative index of the seminomas was determined by immunohistochemical staining for DNA topoisomerase II-alpha (topo II-alpha) a new marker of cell proliferation. AU seminomas had easily detectable topo II-alpha. The average topo II-alpha index of the 20 cases was 52.1 +/- 15.3. Seminomas with elevated topo I had an average topo II-alpha proliferative index of 60.8 +/- 17.5 and seminomas with normal topo I expression had a topo II-alpha proliferative index of 48.4 +/- 13.2. This is significantly different at the 0.05% confidence level. Focal expression of CD30 was seen in 60% (12/20) of the neoplasms. None of the cases showed positive staining for CD15 and c-erbB-2. Our results suggest that chemotherapeutic protocols involving topoisomerase targeting drugs might be useful against testicular seminomas.
