Trial Based on Encouraging Data in CD30-Expressing Relapsed/Refractory DLBCL, the Most Common Type of Aggressive Non-Hodgkin Lymphoma
BOTHELL, WA, USA I October 19, 2015 I Seattle Genetics, Inc. (NASDAQ: SGEN) today announced the initiation of a randomized phase 2 clinical trial of Rituxan (rituximab) and bendamustine with or without ADCETRIS (brentuximab vedotin) in relapsed or refractory patients with CD30-expressing diffuse large B-cell lymphoma (DLBCL). The study is intended to evaluate the activity and safety of the combination regimen. ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30, a protein found on the surface of certain types of cells. CD30 is expressed in several types of non-Hodgkin lymphoma, including at least 25 percent of patients with DLBCL. ADCETRIS is currently not approved for the treatment of DLBCL.
“Diffuse large B-cell lymphoma, or DLBCL, is the most common type of aggressive non-Hodgkin lymphoma. DLBCL patients who relapse following initial treatment often receive salvage therapy sometimes followed by an autologous stem cell transplant, after which most patients will eventually relapse,” said Jonathan Drachman, M.D., Chief Medical Officer and Executive Vice President, Research and Development at Seattle Genetics. “This trial is designed to build on the single-agent activity we have observed with ADCETRIS in CD30-expressing DLBCL, including both relapsed and refractory status. Our goal is to improve long-term outcomes for relapsed and refractory DLBCL patients who express CD30 at detectable levels by combining ADCETRIS with Rituxan and bendamustine, two agents that are commonly used in this disease setting.”
In this phase 2 randomized, open-label, multi-center clinical trial, approximately 110 relapsed/refractory CD30-expressing DLBCL patients will receive Rituxan and bendamustine either with or without ADCETRIS every three weeks for six cycles. Patients in the ADCETRIS combination arm who respond to treatment with a manageable safety profile may continue to receive single-agent ADCETRIS treatment for up to 10 additional cycles. The primary endpoint is to compare the objective response rates between the two study arms. Secondary endpoints include progression-free survival, complete remission rate, duration of response and overall survival. The study is being conducted at approximately 50 sites across North America and Europe.
At the 2015 International Conference on Malignant Lymphoma (ICML), data were presented from an ongoing phase 2 trial for relapsed/refractory CD30-positive non-Hodgkin lymphoma that included DLBCL patients who received single-agent ADCETRIS or in combination with Rituxan every three weeks. Of the 48 patients treated in the single-agent arm, the objective response rate was 44 percent, including 19 percent complete remissions and 25 percent partial remissions. Of the 13 patients treated in the combination arm, the objective response rate was 46 percent, including 15 percent complete remissions and 31 percent partial remissions. The most common treatment-emergent adverse events of any grade occurring in more than 15 percent of all patients enrolled were fatigue, nausea, neutropenia, diarrhea, peripheral sensory neuropathy, fever and vomiting. The most common treatment-emergent adverse event Grade 3 or higher was neutropenia.
Seattle Genetics is also evaluating ADCETRIS in newly diagnosed DLBCL patients through an ongoing phase 2 clinical trial evaluating ADCETRIS in combination with RCHP (rituximab, cyclophosphamide, doxorubicin and prednisone).

About Lymphoma
Lymphoma is a general term for a group of cancers that originate in the lymphatic system. There are two major categories of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. Non-Hodgkin lymphoma represents a diverse group of cancers that develop in the lymphatic system and are characterized by uncontrolled growth and accumulation of abnormal lymphocytes. Lymphocytes are a type of blood cells that are responsible for defending the body against infection. The most common forms of non-Hodgkin lymphoma are diffuse large B-cell lymphoma (an aggressive subtype) and follicular lymphoma (an indolent subtype).
About ADCETRIS
ADCETRIS is being evaluated broadly in more than 30 ongoing clinical trials, including the phase 3 ALCANZA trial and two additional phase 3 studies, one in frontline classical HL and one in frontline mature T-cell lymphomas, as well as trials in many additional types of CD30-expressing malignancies, including B-cell lymphomas.
ADCETRIS is an ADC comprising an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE), utilizing Seattle Genetics’ proprietary technology. The ADC employs a linker system that is designed to be stable in the bloodstream but to release MMAE upon internalization into CD30-expressing tumor cells.
ADCETRIS for intravenous injection has received approval from the FDA for three indications: (1) regular approval for the treatment of patients with classical HL after failure of autologous hematopoietic stem cell transplantation (auto-HSCT) or after failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (2) regular approval for the treatment of classical HL patients at high risk of relapse or progression as post-auto-HSCT consolidation, and (3) accelerated approval for the treatment of patients with systemic anaplastic large cell lymphoma (sALCL) after failure of at least one prior multi-agent chemotherapy regimen. The sALCL indication is approved under accelerated approval based on overall response rate. Continued approval for the sALCL indication may be contingent upon verification and description of clinical benefit in confirmatory trials. Health Canada granted ADCETRIS approval with conditions for relapsed or refractory HL and sALCL.
ADCETRIS was granted conditional marketing authorization by the European Commission in October 2012 for two indications: (1) for the treatment of adult patients with relapsed or refractory CD30-positive HL following autologous stem cell transplant (ASCT), or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option, and (2) the treatment of adult patients with relapsed or refractory sALCL. ADCETRIS has received marketing authorization by regulatory authorities in more than 55 countries. See important safety information below.
Seattle Genetics and Takeda are jointly developing ADCETRIS. Under the terms of the collaboration agreement, Seattle Genetics has U.S. and Canadian commercialization rights and Takeda has rights to commercialize ADCETRIS in the rest of the world. Seattle Genetics and Takeda are funding joint development costs for ADCETRIS on a 50:50 basis, except in Japan where Takeda is solely responsible for development costs.

ADCETRIS (brentuximab vedotin) U.S. Important Safety Information
BOXED WARNING
Progressive multifocal leukoencephalopathy (PML): JC virus infection resulting in PML and death can occur in patients receiving ADCETRIS® (brentuximab vedotin).
Contraindication
ADCETRIS is contraindicated with concomitant bleomycin due to pulmonary toxicity (e.g., interstitial infiltration and/or inflammation).
Warnings and Precautions
- Peripheral neuropathy: ADCETRIS treatment causes a peripheral neuropathy that is predominantly sensory. Cases of peripheral motor neuropathy have also been reported. ADCETRIS-induced peripheral neuropathy is cumulative. Monitor patients for symptoms of neuropathy, such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain or weakness and institute dose modifications accordingly.
- Anaphylaxis and infusion reactions: Infusion-related reactions, including anaphylaxis, have occurred with ADCETRIS. Monitor patients during infusion. If an infusion-related reaction occurs, interrupt the infusion and institute appropriate medical management. If anaphylaxis occurs, immediately and permanently discontinue the infusion and administer appropriate medical therapy.
- Hematologic toxicities: Prolonged (≥1 week) severe neutropenia and Grade 3 or 4 thrombocytopenia or anemia can occur with ADCETRIS. Febrile neutropenia has been reported with ADCETRIS. Monitor complete blood counts prior to each dose of ADCETRIS and consider more frequent monitoring for patients with Grade 3 or 4 neutropenia. Monitor patients for fever. If Grade 3 or 4 neutropenia develops, consider dose delays, reductions, discontinuation, or G-CSF prophylaxis with subsequent doses.
- Serious infections and opportunistic infections: Infections such as pneumonia, bacteremia, and sepsis or septic shock (including fatal outcomes) have been reported in patients treated with ADCETRIS. Closely monitor patients during treatment for the emergence of possible bacterial, fungal or viral infections.
- Tumor lysis syndrome: Closely monitor patients with rapidly proliferating tumor and high tumor burden.
- Increased toxicity in the presence of severe renal impairment: The frequency of ≥Grade 3 adverse reactions and deaths was greater in patients with severe renal impairment compared to patients with normal renal function. Avoid the use of ADCETRIS in patients with severe renal impairment.
- Increased toxicity in the presence of moderate or severe hepatic impairment: The frequency of ≥Grade 3 adverse reactions and deaths was greater in patients with moderate or severe hepatic impairment compared to patients with normal hepatic function. Avoid the use of ADCETRIS in patients with moderate or severe hepatic impairment.
- Hepatotoxicity: Serious cases of hepatotoxicity, including fatal outcomes, have occurred with ADCETRIS. Cases were consistent with hepatocellular injury, including elevations of transaminases and/or bilirubin, and occurred after the first dose of ADCETRIS or rechallenge. Preexisting liver disease, elevated baseline liver enzymes, and concomitant medications may also increase the risk. Monitor liver enzymes and bilirubin. Patients experiencing new, worsening, or recurrent hepatotoxicity may require a delay, change in dose, or discontinuation of ADCETRIS.
- Progressive multifocal leukoencephalopathy (PML): JC virus infection resulting in PML and death has been reported in ADCETRIS-treated patients. First onset of symptoms occurred at various times from initiation of ADCETRIS therapy, with some cases occurring within 3 months of initial exposure. In addition to ADCETRIS therapy, other possible contributory factors include prior therapies and underlying disease that may cause immunosuppression. Consider the diagnosis of PML in any patient presenting with new-onset signs and symptoms of central nervous system abnormalities. Hold ADCETRIS if PML is suspected and discontinue ADCETRIS if PML is confirmed.
- Pulmonary Toxicity: Events of noninfectious pulmonary toxicity including pneumonitis, interstitial lung disease, and acute respiratory distress syndrome, some with fatal outcomes, have been reported. Monitor patients for signs and symptoms of pulmonary toxicity, including cough and dyspnea. In the event of new or worsening pulmonary symptoms, hold ADCETRIS dosing during evaluation and until symptomatic improvement.
- Serious dermatologic reactions: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), including fatal outcomes, have been reported with ADCETRIS. If SJS or TEN occurs, discontinue ADCETRIS and administer appropriate medical therapy.
- Embryo-fetal toxicity: Fetal harm can occur. Advise pregnant women of the potential hazard to the fetus.
Most Common Adverse Reactions:
ADCETRIS was studied as monotherapy in 160 patients with relapsed classical HL and sALCL in two uncontrolled single-arm trials. Across both trials, the most common adverse reactions (≥20%), regardless of causality, were neutropenia, peripheral sensory neuropathy, fatigue, nausea, anemia, upper respiratory tract infection, diarrhea, pyrexia, rash, thrombocytopenia, cough and vomiting.
ADCETRIS was studied in 329 patients with classical HL at high risk of relapse or progression post-auto-HSCT in a placebo-controlled randomized trial. The most common adverse reactions (≥20%) in the ADCETRIS-treatment arm (167 patients), regardless of causality, were neutropenia, peripheral sensory neuropathy, thrombocytopenia, anemia, upper respiratory tract infection, fatigue, peripheral motor neuropathy, nausea, cough, and diarrhea.
Drug Interactions:
Concomitant use of strong CYP3A4 inhibitors or inducers, or P-gp inhibitors, has the potential to affect the exposure to monomethyl auristatin E (MMAE).
Use in Specific Populations:
MMAE exposure and adverse reactions are increased in patients with moderate or severe hepatic impairment or severe renal impairment. Avoid use.
