Seattle Genetics and Takeda Present Positive Data from Phase 3 ECHELON-2 Clinical Trial for ADCETRIS® (Brentuximab Vedotin) in Frontline Treatment of CD30-Expressing Peripheral T-Cell Lymphomas
Seattle Genetics, Inc. (Nasdaq:SGEN) and Takeda Pharmaceutical Company Limited (TSE:4502) announced that data from the ECHELON-2 phase 3 clinical trial will be presented today in an oral session at the 60th American Society of Hematology (ASH) Annual Meeting. The data demonstrated that frontline treatment with ADCETRIS (brentuximab vedotin) in combination with CHP (cyclophosphamide, doxorubicin, prednisone) is effective in extending progression-free survival (PFS) and overall survival (OS) with a safety profile comparable to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), a current standard of care in patients with CD30-expressing peripheral T-cell lymphomas (PTCL). These data were also simultaneously published online in The Lancet. ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30, which is expressed on the surface of several types of PTCL.

The positive topline results of the ECHELON-2 phase 3 clinical trial were previously reported in October 2018. In November 2018, ADCETRIS was approved by the U.S. Food and Drug Administration (FDA) for adults with previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing PTCL, including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with CHP. The ECHELON-2 data were the basis of a supplemental Biologics License Application (BLA), which was reviewed by the FDA under its Real-Time Oncology Review Pilot Program and approved less than two weeks after complete submission of the supplemental BLA.
“As clinicians, we are always searching for new strategies to address unmet needs in aggressive blood cancers, and ADCETRIS has proven to be one of those agents that has shown benefit for patients in multiple types of lymphoma and now in frontline PTCL,” said Steven Horwitz, M.D., Department of Medicine, Lymphoma Service, Memorial Sloan Kettering Cancer Center, New York. “This research is important for patients because clinicians now have a novel approach for treating newly diagnosed patients with CD30-expressing PTCL, a group of aggressive cancers. The ECHELON-2 data demonstrates that ADCETRIS plus CHP is superior in extending both progression-free survival and overall survival compared to a current standard of care, CHOP, a multi-agent chemotherapy regimen we have been using in practice for several decades.”
“This is the sixth FDA-approved indication for ADCETRIS in lymphoid malignancies and the second as a frontline treatment in combination with chemotherapy,” said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics. “The data presented today at ASH underscores that the ADCETRIS combination provides clinically meaningful benefit to patients with previously untreated PTCL and has the potential to be practice changing for these patients.”
“We are pleased to share these impressive results from the ECHELON-2 trial, which build on the efficacy and safety observed with ADCETRIS in a variety of CD30-positive lymphomas,” said Jesús Gómez-Navarro, M.D., Vice President and Head, Oncology Clinical Research and Development, Takeda. “The study demonstrated clinically meaningful outcomes and was the first randomized phase 3 trial in frontline PTCL to show improvement in overall survival. Establishing an optimal therapy for PTCL has been a challenge for physicians, and these findings represent the progress in addressing the unmet needs of people living with this serious disease. We look forward to working with regulatory authorities in our territory to bring a potential new treatment option to patients with PTCL.”
The ECHELON-2 Trial: Results of a Randomized, Double-Blind, Active-Controlled Phase 3 Study of Brentuximab Vedotin and CHP (A+CHP) Versus CHOP in the Frontline Treatment of Patients with CD30+ Peripheral T-Cell Lymphomas (Abstract #997, oral presentation on Monday, December 3, 2018 at 6:15 p.m. PT at the San Diego Convention Center, Room 6F)
ECHELON-2 is a global, randomized, double-blind, multi-center trial evaluating ADCETRIS as part of a frontline combination chemotherapy regimen in patients with previously untreated CD30-expressing PTCL. The primary endpoint is PFS per Blinded Independent Central Review (BICR), with events defined as progression, death, or receipt of chemotherapy for residual or progressive disease. Key secondary endpoints include PFS in patients with sALCL, complete remission (CR) rate, OS and objective response rate (ORR). ECHELON-2 enrolled 452 patients (226 in each arm) at 132 sites in 17 countries across North America, Europe, Asia Pacific and the Middle East. The median age of patients was 58 years. The study enrolled patients with advanced disease (80 percent) and most patients had sALCL (48 percent ALK-negative and 22 percent ALK-positive).
Key findings, which will be presented by Dr. Steven Horwitz and published in The Lancet, include:
- The ECHELON-2 study met its primary endpoint with ADCETRIS plus CHP demonstrating a statistically significant improvement in PFS as assessed by a BICR (hazard ratio [HR]=0.71; p-value=0.0110). This corresponds to a 29 percent reduction in the risk of progression, death or need for additional anticancer therapy for residual or progressive disease.
- After a median follow-up time of 36.2 months, the median PFS in the ADCETRIS plus CHP arm was 48.2 months (95% CI, 35.2-not evaluable) compared to 20.8 months (95% CI, 12.7-47.6) in the control arm per BICR assessment. The three-year PFS was 57.1 percent for ADCETRIS plus CHP compared to 44.4 percent in the control arm.
- Per investigator assessment, ADCETRIS plus CHP demonstrated a statistically significant improvement in PFS (HR=0.70; p-value=0.0096).
- OS in the ADCETRIS plus CHP arm was statistically significant compared to CHOP (HR=0.66; p-value=0.0244). This corresponds to a 34 percent reduction in the risk of death.
- After a median follow-up of 42.1 months, the median OS was not reached for either arm of the study. The estimated three-year OS was 76.8 percent for ADCETRIS plus CHP compared to 69.1 percent for CHOP.
- All other key secondary endpoints, including CR rate and ORR, in addition to PFS in patients with sALCL, were statistically significant in favor of the ADCETRIS plus CHP arm. Per BICR assessment, the CR rate (68 percent versus 56 percent, respectively) and ORR (83 percent versus 72 percent, respectively) for the ADCETRIS plus CHP arm were significantly higher than those treated with CHOP (p-value=0.0066 and p-value=0.0032, respectively). Per investigator assessment, the CR rate and ORR showed a similar benefit for the ADCETRIS plus CHP arm versus CHOP (p-value=0.0043 and p-value=0.0018, respectively).
- Excluding consolidative stem cell transplant or radiotherapy for consolidation of response to initial therapy, 74 percent of patients in the ADCETRIS plus CHP arm versus 58 percent of patients in the CHOP arm did not require subsequent anticancer therapies for residual or progressive disease. Of the 226 patients who received CHOP, 49 patients (22 percent) received subsequent treatment with an ADCETRIS-containing therapy.
The safety profile of ADCETRIS plus CHP in the ECHELON-2 trial was
comparable to CHOP and consistent with the established safety profile
of ADCETRIS in combination with chemotherapy.
- The most common treatment-related adverse events of any grade occurring in 20 percent or more of patients in the ADCETRIS plus CHP and CHOP arm were: nausea (46 and 38 percent, respectively), peripheral sensory neuropathy (45 and 41 percent, respectively), neutropenia (38 percent each), diarrhea (38 and 20 percent, respectively), constipation (29 and 30 percent, respectively), alopecia (26 and 25 percent, respectively), pyrexia (26 and 19 percent, respectively), vomiting (26 and 17 percent, respectively), fatigue (24 and 20 percent, respectively) and anaemia (21 and 16 percent, respectively).
- The most common Grade 3 or higher adverse events occurring in the ADCETRIS plus CHP and CHOP arms were neutropenia (35 and 34 percent, respectively) and anaemia (13 and 10 percent, respectively).
- The incidence and severity of neutropenia was similar between study arms, and lower in the subset of patients who received primary prophylaxis with granulocyte-colony stimulating factor. Febrile neutropenia was reported in 41 patients (18 percent) in the ADCETRIS plus CHP arm and 33 patients (15 percent) in the CHOP arm.
- New or worsening treatment-emergent peripheral neuropathy events occurred in 117 patients (52 percent) in the ADCETRIS plus CHP arm and 124 patients (55 percent) in the CHOP arm, with a majority at a maximum severity of Grade 1 (64 and 71 percent, respectively). At last follow-up, peripheral neuropathy returned to baseline or lower in 50 percent of the patients in the ADCETRIS plus CHP arm versus 64 percent in the CHOP arm, and the median time to resolution was 17 weeks and 11.4 weeks, respectively.
- Adverse events leading to death occurred in seven patients (three percent) in the ADCETRIS plus CHP arm and nine patients (four percent) in the CHOP arm.

About T-Cell Lymphomas
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. There are more than 60 subtypes of non-Hodgkin lymphomas which are broadly divided into two major groups: B-cell lymphomas, which develop from abnormal B-lymphocytes, and T-cell lymphomas, which develop from abnormal T-lymphocytes. There are many different forms of T-cell lymphomas, some of which are extremely rare. T-cell lymphomas can be aggressive (fast-growing) or indolent (slow-growing). PTCL accounts for approximately 10 percent of non-Hodgkin lymphoma cases in the U.S. and Europe and may be as high as 24 percent in parts of Asia.
About ADCETRIS (brentuximab vedotin)
ADCETRIS is being evaluated broadly in more than 70 clinical trials in CD30-expressing lymphomas. These include the completed phase 3 ECHELON-2 trial in frontline peripheral T-cell lymphomas (also known as mature T-cell lymphoma), the completed phase 3 ECHELON-1 trial in previously untreated Hodgkin lymphoma, the completed phase 3 ALCANZA trial in cutaneous T-cell lymphoma.
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 injection for intravenous infusion has received FDA approval for six indications in adult patients with: (1) previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with cyclophosphamide, doxorubicin, and prednisone, (2) previously untreated Stage III or IV classical Hodgkin lymphoma (cHL), in combination with doxorubicin, vinblastine, and dacarbazine, (3) cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation, (4) cHL after failure of auto-HSCT or failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (5) sALCL after failure of at least one prior multi-agent chemotherapy regimen, and (6) primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.
Health Canada granted ADCETRIS approval with conditions for relapsed or refractory Hodgkin lymphoma and sALCL in 2013, and non-conditional approval for post-autologous stem cell transplantation (ASCT) consolidation treatment of Hodgkin lymphoma patients at increased risk of relapse or progression.
ADCETRIS received conditional marketing authorization from the European Commission in October 2012. The approved indications in Europe are: (1) for the treatment of adult patients with relapsed or refractory CD30-positive Hodgkin lymphoma following ASCT, or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option, (2) the treatment of adult patients with relapsed or refractory sALCL, (3) for the treatment of adult patients with CD30-positive Hodgkin lymphoma at increased risk of relapse or progression following ASCT, and (4) for the treatment of adult patients with CD30-positive cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy.
ADCETRIS has received marketing authorization by regulatory authorities in 72 countries for relapsed or refractory Hodgkin lymphoma and sALCL. See select important safety information, including Boxed Warning, below.

ADCETRIS (brentuximab vedotin) Important Safety Information
BOXED WARNING: PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML):
JC virus infection resulting in PML and death can occur in ADCETRIS-treated patients.
ADCETRIS concomitant with bleomycin due to pulmonary toxicity (e.g., interstitial infiltration and/or inflammation).
Warnings and Precautions
- Peripheral neuropathy (PN): ADCETRIS causes PN that is predominantly sensory. Cases of motor PN have also been reported. ADCETRIS-induced PN is cumulative. Monitor for symptoms such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain, or weakness. Institute dose modifications accordingly.
- Anaphylaxis and infusion reactions: Infusion-related reactions (IRR), including anaphylaxis, have occurred with ADCETRIS. Monitor patients during infusion. If an IRR occurs, interrupt the infusion and institute appropriate medical management. If anaphylaxis occurs, immediately and permanently discontinue the infusion and administer appropriate medical therapy. Premedicate patients with a prior IRR before subsequent infusions. Premedication may include acetaminophen, an antihistamine, and a corticosteroid.
- Hematologic toxicities: Fatal and serious cases of febrile neutropenia have been reported with ADCETRIS. Prolonged (≥1 week) severe neutropenia and Grade 3 or 4 thrombocytopenia or anemia can occur with ADCETRIS. Start primary prophylaxis with G-CSF beginning with Cycle 1 for patients who receive ADCETRIS in combination with chemotherapy for previously untreated Stage III or IV classical HL or previously untreated PTCL. Monitor complete blood counts prior to each ADCETRIS dose. Monitor more frequently 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 ADCETRIS doses.
- Serious infections and opportunistic infections: Infections such as pneumonia, bacteremia, and sepsis or septic shock (including fatal outcomes) have been reported in ADCETRIS-treated patients. Closely monitor patients during treatment for 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 use 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 use in patients with moderate or severe hepatic impairment.
- Hepatotoxicity: Fatal and serious cases have occurred in ADCETRIS-treated patients. Cases were consistent with hepatocellular injury, including elevations of transaminases and/or bilirubin, and occurred after the first ADCETRIS dose or rechallenge. Preexisting liver disease, elevated baseline liver enzymes, and concomitant medications may increase the risk. Monitor liver enzymes and bilirubin. Patients with new, worsening, or recurrent hepatotoxicity may require a delay, change in dose, or discontinuation of ADCETRIS.
- PML: Fatal cases of JC virus infection resulting in PML and death have 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. Other possible contributory factors other than ADCETRIS include prior therapies and underlying disease that may cause immunosuppression. Consider PML diagnosis in patients 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: Fatal and serious events of noninfectious pulmonary toxicity including pneumonitis, interstitial lung disease, and acute respiratory distress syndrome have been reported. Monitor patients for signs and symptoms, 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: Fatal and serious cases of Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with ADCETRIS. If SJS or TEN occurs, discontinue ADCETRIS and administer appropriate medical therapy.
- Gastrointestinal (GI) complications: Fatal and serious cases of acute pancreatitis have been reported. Other fatal and serious GI complications include perforation, hemorrhage, erosion, ulcer, intestinal obstruction, enterocolitis, neutropenic colitis, and ileus. Lymphoma with preexisting GI involvement may increase the risk of perforation. In the event of new or worsening GI symptoms, perform a prompt diagnostic evaluation and treat appropriately.
- Embryo-fetal toxicity: Based on the mechanism of action and animal studies, ADCETRIS can cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus, and to avoid pregnancy during ADCETRIS treatment and for at least 6 months after the final dose of ADCETRIS.
Most Common (≥20% in any study) Adverse Reactions: Peripheral neuropathy, fatigue, nausea, diarrhea, neutropenia, upper respiratory tract infection, pyrexia, constipation, vomiting, alopecia, decreased weight, abdominal pain, anemia, stomatitis, lymphopenia and mucositis.
Concomitant use of strong CYP3A4 inhibitors or inducers has the potential to affect the exposure to monomethyl auristatin E (MMAE).
Use in Specific Populations
Moderate or severe hepatic impairment or severe renal impairment: MMAE exposure and adverse reactions are increased. Avoid use.
Advise males with female sexual partners of reproductive potential to use effective contraception during ADCETRIS treatment and for at least 6 months after the final dose of ADCETRIS.
Advise patients to report pregnancy immediately and avoid breastfeeding while receiving ADCETRIS.
ADCETRIS (brentuximab vedotin) Important Safety Information (European Union)
Please refer to Summary of Product Characteristics (SmPC) before prescribing.
ADCETRIS is contraindicated for patients with hypersensitivity to brentuximab vedotin and its excipients. In addition, combined use of ADCETRIS with bleomycin causes pulmonary toxicity.
SPECIAL WARNINGS & PRECAUTIONS
Progressive multifocal leukoencephalopathy (PML): John Cunningham virus (JCV) reactivation resulting in progressive multifocal leukoencephalopathy (PML) and death can occur in patients treated with ADCETRIS. PML has been reported in patients who received ADCETRIS after receiving multiple prior chemotherapy regimens. PML is a rare demyelinating disease of the central nervous system that results from reactivation of latent JCV and is often fatal.
Closely monitor patients for new or worsening neurological, cognitive, or behavioral signs or symptoms, which may be suggestive of PML. Suggested evaluation of PML includes neurology consultation, gadolinium-enhanced magnetic resonance imaging of the brain, and cerebrospinal fluid analysis for JCV DNA by polymerase chain reaction or a brain biopsy with evidence of JCV. A negative JCV PCR does not exclude PML. Additional follow up and evaluation may be warranted if no alternative diagnosis can be established Hold dosing for any suspected case of PML and permanently discontinue ADCETRIS if a diagnosis of PML is confirmed. Be alert to PML symptoms that the patient may not notice (e.g., cognitive, neurological, or psychiatric symptoms).
Pancreatitis: Acute pancreatitis has been observed in patients treated with ADCETRIS. Fatal outcomes have been reported. Closely monitor patients for new or worsening abdominal pain, which may be suggestive of acute pancreatitis. Patient evaluation may include physical examination, laboratory evaluation for serum amylase and serum lipase, and abdominal imaging, such as ultrasound and other appropriate diagnostic measures. Hold ADCETRIS for any suspected case of acute pancreatitis. ADCETRIS should be discontinued if a diagnosis of acute pancreatitis is confirmed.
Pulmonary Toxicity: Cases of pulmonary toxicity, some with fatal outcomes, including pneumonitis, interstitial lung disease, and acute respiratory distress syndrome (ARDS), have been reported in patients receiving ADCETRIS. Although a causal association with ADCETRIS has not been established, the risk of pulmonary toxicity cannot be ruled out. Promptly evaluate and treat new or worsening pulmonary symptoms appropriately. Consider holding dosing during evaluation and until symptomatic improvement.
Serious infections and opportunistic infections: Serious infections such as pneumonia, staphylococcal bacteremia, sepsis/septic shock (including fatal outcomes), and herpes zoster, and opportunistic infections such as Pneumocystis jiroveci pneumonia and oral candidiasis have been reported in patients treated with ADCETRIS. Carefully monitor patients during treatment for emergence of possible serious and opportunistic infections.
Infusion-related reactions (IRR): Immediate and delayed IRR, as well as anaphylaxis, have occurred with ADCETRIS. Carefully monitor patients during and after an infusion. If anaphylaxis occurs, immediately and permanently discontinue administration of ADCETRIS Appropriate medical therapy should be administered. If an IRR occurs, interrupt the infusion and institute appropriate medical management. The infusion may be restarted at a slower rate after symptom resolution. Patients who have experienced a prior IRR should be premedicated for subsequent infusions. IRRs are more frequent and more severe in patients with antibodies to ADCETRIS.
Tumor lysis syndrome (TLS): TLS has been reported with ADCETRIS. Patients with rapidly proliferating tumor and high tumor burden are at risk of TLS. Monitor these patients closely and managed according to best medical practice.
Peripheral neuropathy (PN): ADCETRIS treatment may cause PN, both sensory and motor. ADCETRIS-induced PN is typically cumulative and reversible in most cases. Monitor patients for symptoms of PN, such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain, or weakness. Patients experiencing new or worsening PN may require a delay and a dose reduction or discontinuation of ADCETRIS.
Hematological toxicities: Grade 3 or Grade 4 anemia, thrombocytopenia, and prolonged (equal to or greater than one week) Grade 3 or Grade 4 neutropenia can occur with ADCETRIS. Monitor complete blood counts prior to administration of each dose.
Febrile neutropenia: Febrile neutropenia has been reported. Closely monitor patients for fever and manage according to best medical practice if febrile neutropenia develops.
Stevens-Johnson syndrome (SJS): SJS and toxic epidermal necrolysis (TEN) have been reported with ADCETRIS. Fatal outcomes have been reported. Discontinue treatment with ADCETRIS if SJS or TEN occurs and administer appropriate medical therapy.
Gastrointestinal (GI) Complications: GI complications, some with fatal outcomes, including intestinal obstruction, ileus, enterocolitis, neutropenic colitis, erosion, ulcer, perforation and haemorraghe, have been reported. Promptly evaluate and treat patients if new or worsening GI symptoms occur.
Hepatotoxicity: Elevations in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) have been reported. Serious cases of hepatotoxicity, including fatal outcomes, have also occurred. Test liver function prior to treatment initiation and routinely monitor patients receiving ADCETRIS for liver elevations. Patients experiencing hepatotoxicity may require a delay, dose modification, or discontinuation of ADCETRIS.
Hyperglycemia: Hyperglycemia has been reported during trials in patients with an elevated body mass index (BMI) with or without a history of diabetes mellitus. Closely monitor serum glucose for patients who experiences an event of hyperglycemia. Administer anti-diabetic treatment as appropriate.
Renal and Hepatic Impairment: There is limited experience in patients with renal and hepatic impairment. Available data indicate that MMAE clearance might be affected by severe renal impairment, hepatic impairment, and by low serum albumin concentrations.
CD30+ CTCL: The size of the treatment effect in CD30 + CTCL subtypes other than mycosis fungoides (MF) and primary cutaneous anaplastic large cell lymphoma (pcALCL) is not clear due to lack of high level evidence. In two single arm phase II studies of ADCETRIS, disease activity has been shown in the subtypes Sézary syndrome (SS), lymphomatoid papulosis (LyP) and mixed CTCL histology. These data suggest that efficacy and safety can be extrapolated to other CTCL CD30+ subtypes. Carefully consider the benefit-risk per patient and use caution in other CD30+ CTCL patient types.
Sodium content in excipients: ADCETRIS contains a maximum of 2.1 mmol (or 47 mg) of sodium per dose. Take this into consideration for patients on a controlled sodium diet.
Patients who are receiving a strong CYP3A4 and P-gp inhibitor, concomitantly with ADCETRIS may have an increased risk of neutropenia and should be closely monitored. Co-administration of ADCETRIS with a CYP3A4 inducer did not alter the plasma exposure of ADCETRIS but it appeared to reduce plasma concentrations of MMAE metabolites that could be assayed. ADCETRIS is not expected to alter the exposure to drugs that are metabolized by CYP3A4 enzymes.
PREGNANCY: Advise women of childbearing potential to use two methods of effective contraception during treatment with ADCETRIS and until 6 months after treatment. There are no data from the use of ADCETRIS in pregnant women, although studies in animals have shown reproductive toxicity. Do not use ADCETRIS during pregnancy unless the benefit to the mother outweighs the potential risks to the fetus.
LACTATION (breast-feeding): There are no data as to whether ADCETRIS or its metabolites are excreted in human milk, therefore a risk to the newborn/infant cannot be excluded. With the potential risk, a decision should be made whether to discontinue breast-feeding or discontinue/abstain from therapy with ADCETRIS.
FERTILITY: In nonclinical studies, ADCETRIS treatment has resulted in testicular toxicity, and may alter male fertility. Advise men being treated with ADCETRIS not to father a child during treatment and for up to 6 months following the last dose.
Effects on ability to drive and use machines: ADCETRIS may have a minor influence on the ability to drive and use machines.
The most frequent adverse reactions (≥10%) were infections, peripheral sensory neuropathy, nausea, fatigue, diarrhoea, pyrexia, upper respiratory tract infection, neutropenia, rash, cough, vomiting, arthralgia, peripheral motor neuropathy, infusion-related reactions, pruritus, constipation, dyspnoea, weight decreased, myalgia and abdominal pain.
Serious adverse drug reactions were: pneumonia, acute respiratory distress syndrome, headache, neutropenia, thrombocytopenia, constipation, diarrhea, vomiting, nausea, pyrexia, peripheral motor neuropathy, peripheral sensory neuropathy, hyperglycemia, demyelinating polyneuropathy, tumor lysis syndrome, and Stevens-Johnson syndrome. Serious adverse drug reactions occurred in 12% of patients. The frequency of unique serious adverse drug reactions was ≤1%.
