– If Authorized in Europe, ADCETRIS in Combination with AVD (Adriamycin, Vinblastine and Dacarbazine) Will Be the First New Treatment Regimen Available for Adult Patients with Previously Untreated CD30+ Stage IV Hodgkin Lymphoma in Decades
– Opinion Based on Positive Phase 3 ECHELON-1 Study Results, Which Demonstrated ADCETRIS Combination Improved Outcomes and Reduced the Need for Additional Treatment in Adult Patients Versus ABVD (Adriamycin, Bleomycin, Vinblastine and Dacarbazine), a Current Standard of Care
Cambridge, Mass. and Osaka, Japan, December 14, 2018 – Takeda Pharmaceutical Company Limited (TSE: 4502) today announced that the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for the extension of the marketing authorization of ADCETRIS (brentuximab vedotin) and recommended its approval in combination with AVD in adult patients with previously untreated CD30+ Stage IV Hodgkin lymphoma. ADCETRIS is an antibody-drug conjugate (ADC) directed at CD30, a defining marker of Hodgkin lymphoma. ADCETRIS is currently not approved as a therapy for previously untreated Hodgkin lymphoma in Europe.
“For a large number of previously untreated Hodgkin lymphoma patients diagnosed with Stage IV disease, progression will occur with current treatments, highlighting a true unmet need in this population,” said Anna Sureda, M.D., Ph.D., Head of the Hematology Department and Hematopoietic Stem Cell Transplant Programme, Institut Català d'Oncologia - Hospital Duran i Reynals. “In the ECHELON-1 clinical trial, ADCETRIS in combination with AVD reduced the risk of progression, death or need for subsequent anticancer therapy in patients with Stage IV disease by 29 percent versus ABVD, a standard of care. If approved in this indication, ADCETRIS may offer an important novel treatment option for previously untreated patients with Stage IV Hodgkin lymphoma in Europe.”
“Today’s positive CHMP opinion represents a significant step forward for the European Hodgkin lymphoma community,” said Jesús Gómez-Navarro, M.D., Vice President, Head of Oncology Clinical Research and Development, Takeda. “The results of the ECHELON-1 trial demonstrated a statistically significant improvement in modified progression-free survival of in patients who received ADCETRIS in combination with AVD compared to the control arm. In addition to demonstrating a safety profile that was generally consistent with that known for the single-agent components of the regimen, in the ADCETRIS containing arm, 35 percent fewer patients with Stage IV disease received subsequent salvage chemotherapy or high-dose chemotherapy and transplant. We look forward to the European Commission’s review of this CHMP positive opinion and hope to offer ADCETRIS as a treatment option to appropriate European Hodgkin lymphoma patients in the future.”
The submission for ADCETRIS will now be reviewed by the European Commission (EC), which has the authority to approve medicines for use in the 28-member states of the European Union (EU). Decisions by the EC are also applicable in Norway, Liechtenstein and Iceland.
The positive CHMP opinion is based on the results of the Phase 3 ECHELON-1 study designed to compare ADCETRIS plus AVD to ABVD as a therapy in adult patients with previously untreated Hodgkin lymphoma. The trial achieved its primary endpoint resulting in a statistically significant improvement in modified progression-free survival (PFS) versus the control arm (HR 0.77; p-value=0.035). Key subgroup analyses, such as modified PFS by disease stage, showed a larger effect in patients with Stage IV Hodgkin lymphoma in the ADCETRIS plus AVD arm versus the control arm (HR 0.71; p-value = 0.023). This corresponds to a 29 percent reduction in the risk of progression, death or need for additional anticancer therapy for Stage IV patients.
About the ECHELON-1 Trial
The randomized, open-label, two-arm, multi-center Phase 3 ECHELON-1 trial achieved its primary endpoint with the combination of ADCETRIS+AVD resulting in a statistically significant improvement in modified progression-free survival (PFS) versus the control arm of ABVD as assessed by an Independent Review Facility (IRF) (HR 0.77; p-value=0.035). This corresponds to a 23 percent reduction in the risk of progression, death or need for additional anticancer therapy.
About Hodgkin 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. Hodgkin lymphoma is distinguished from other types of lymphoma by the presence of one characteristic type of cell, known as the Reed-Sternberg cell. The Reed-Sternberg cell expresses CD30.
According to the Lymphoma Coalition, approximately 67,000 people worldwide are diagnosed with Hodgkin lymphoma each year and more than 25,000 people die each year from this cancer.
Up to 30 percent of previously untreated Hodgkin lymphoma patients progress following their first therapy depending on the stage of the disease. Only 50 percent of patients with relapsed or refractory Hodgkin lymphoma achieve long-term remission with high-dose chemotherapy and an autologous stem cell transplant (ASCT), a historically used treatment regimen, highlighting the need for successful treatments for previously untreated patients.
ADCETRIS is an antibody-drug conjugate (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-positive 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 transplant (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 more than 70 countries for relapsed or refractory Hodgkin lymphoma and sALCL. See important safety information below.
ADCETRIS is being evaluated broadly in more than 70 clinical trials, including a Phase 3 study in first-line Hodgkin lymphoma (ECHELON-1) and another Phase 3 study in first-line CD30-positive peripheral T-cell lymphomas (ECHELON-2), as well as trials in many additional types of CD30-positive malignancies.
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.
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%.
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
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.
