Anaplastic Large-Cell Lymphoma

ECHELON-3 trial of ADCETRIS in combination with lenalidomide and rituximab showed significant improvement in primary endpoint of overall survival and in secondary endpoints of progression free survival and overall response rate versus lenalidomide and rituximab plus placebo, regardless of CD30 expression Pfizer to discuss regulatory submission with FDA, potentially leading to eighth indication for ADCETRIS NEW YORK--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE) today announced that a Phase 3 study of the antibody-drug conjugate ADCETRIS® (brentuximab vedotin) in combination with lenalidomide and rituximab for the treatment of patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) showed a statistically significant and clinically meaningful improvement in overall survival (OS) compared to lenalidomide and rituximab plus placebo. Positive outcomes were also observed in key secondary endpoints, including progression free survival (PFS) and overall response rate (ORR). The safety and tolerability of ADCETRIS in the ECHELON-3 trial were consistent with what has been previously presented for patients with relapsed/refractory DLBCL treated with ADCETRIS in clinical trials. Full data will be submitted for presentation at an upcoming medical meeting. “This is the third Phase 3 study in a type of lymphoma to demonstrate an overall survival benefit for an ADCETRIS combination. Based on the strong results from ECHELON-3, we’re excited that ADCETRIS could address an area of high unmet need in patients with relapsed or refractory DLBCL irrespective of CD30 expression,” said Roger Dansey, M.D., Chief Development Officer, Oncology, Pfizer. “The results are particularly encouraging because the study evaluated heavily pre-treated patients, including some who received prior CAR-T therapy.” DLBCL is the most common type of lymphoma and is a fast-growing, aggressive blood cancer. Approximately 40% of patients with DLBCL do not respond to initial treatment or develop relapsed disease after first-line treatment. ADCETRIS is a standard of care for patients with certain lymphomas and is approved for seven indications in the U.S with more than 55,000 patients treated since its first U.S. approval in 2011. More than 140,000 patients have been treated with ADCETRIS globally. Pfizer plans to share the ECHELON-3 data with the U.S. Food and Drug Administration (FDA) to potentially support regulatory filing in the U.S. About ECHELON-3 ECHELON-3 is an ongoing, randomized, double-blind, multicenter Phase 3 study evaluating ADCETRIS plus lenalidomide and rituximab versus lenalidomide and rituximab plus placebo in adult patients with relapsed/refractory DLBCL, regardless of CD30 expression, who have received two or more prior lines of therapy and are ineligible for stem cell transplant or CAR-T therapy. In this global study, 230 patients were randomized across North America, Europe and Asia-Pacific. The primary endpoint is OS in the intent to treat population, with key secondary endpoints of PFS and ORR as assessed by investigator. Other secondary endpoints include complete response rate, duration of response, safety and tolerability. About Diffuse Large B-cell Lymphoma Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of lymphoma and is an aggressive, difficult to treat disease.1 More than 25,000 cases of DLBCL are diagnosed each year in the United States, accounting for more than 25 percent of all lymphoma cases.2 DLBCL can develop spontaneously or as a result of diseases such as chronic lymphocytic lymphoma/small lymphocytic lymphoma, follicular lymphoma, or marginal zone lymphoma.3 Up to 40 percent of patients relapse or have refractory disease after frontline treatment. About ADCETRIS ADCETRIS is an antibody-drug conjugate (ADC) comprised of a CD30-directed monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE), utilizing Seagen's 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 is approved in seven indications in the U.S.: Adult patients with previously untreated Stage III/IV classical Hodkin lymphoma (cHL) in combination with doxorubicin, vinblastine, and dacarbazine (2018) Pediatric patients 2 years and older with previously untreated high risk cHL in combination with doxorubicin, vincristine, etoposide, prednisone and cyclophosphamide (2022) Adult patients with cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation (2015) Adult patients with cHL after failure of auto-HSCT or after failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates (2011) Adult patients with 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 (2018) Adult patients with sALCL after failure of at least one prior multi-agent chemotherapy regimen. (2011) Adult patients with primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) after prior systemic therapy (2017) Pfizer and Takeda jointly develop ADCETRIS. Under the terms of the collaboration agreement, Pfizer has U.S. and Canadian commercialization rights, and Takeda has rights to commercialize ADCETRIS in the rest of the world. Pfizer 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) for injection U.S. Important Safety Information BOXED WARNING PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML): JC virus infection resulting in PML, and death can occur in ADCETRIS-treated patients. CONTRAINDICATION Contraindicated with concomitant 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. Patients experiencing new or worsening PN may require a delay, change in dose, or discontinuation of ADCETRIS. 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. Administer G-CSF primary prophylaxis beginning with Cycle 1 for adult patients who receive ADCETRIS in combination with chemotherapy for previously untreated Stage III/IV cHL or previously untreated PTCL, and pediatric patients who receive ADCETRIS in combination with chemotherapy for previously untreated high risk cHL. 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 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 infections. Tumor lysis syndrome: Patients with rapidly proliferating tumor and high tumor burden may be at increased risk. Monitor closely and take appropriate measures. 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. 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. 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 have been reported in ADCETRIS-treated patients. First onset of symptoms occurred at various times from initiation of ADCETRIS, 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 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 pre-existing GI involvement may increase the risk of perforation. In the event of new or worsening GI symptoms, including severe abdominal pain, perform a prompt diagnostic evaluation and treat appropriately. Hyperglycemia: Serious cases, such as new-onset hyperglycemia, exacerbation of pre-existing diabetes mellitus, and ketoacidosis (including fatal outcomes) have been reported with ADCETRIS. Hyperglycemia occurred more frequently in patients with high body mass index or diabetes. Monitor serum glucose and if hyperglycemia develops, administer anti-hyperglycemic medications as clinically indicated. Embryo-fetal toxicity: Based on the mechanism of action and animal studies, ADCETRIS can cause fetal harm. Advise females of reproductive potential of this potential risk, and to use effective contraception during ADCETRIS treatment and for 2 months after the last dose of ADCETRIS. Advise male patients with female partners of reproductive potential to use effective contraception during ADCETRIS treatment and for 4 months after the last dose of ADCETRIS. ADVERSE REACTIONS The most common adverse reactions (≥20% in any study) are peripheral neuropathy, fatigue, nausea, diarrhea, neutropenia, upper respiratory tract infection, pyrexia, constipation, vomiting, alopecia, decreased weight, abdominal pain, anemia, stomatitis, lymphopenia, mucositis, thrombocytopenia, and febrile neutropenia. DRUG INTERACTIONS Concomitant use of strong CYP3A4 inhibitors has the potential to affect the exposure to monomethyl auristatin E (MMAE). Closely monitor adverse reactions.

Pictured: Exterior view of Pfizer's office in Belgium/iStock, Alexandros Michailidis Pfizer on Tuesday released results for the Phase III ECHELON-3 study, demonstrating that the antibody-drug conjugate Adcetris (brentuximab vedotin) significantly boosted survival in patients with relapsed/refractory diffuse large B-cell lymphoma when used with lenalidomide and rituximab. The pharma did not provide specific data in its announcement, disclosing only that the Adcetris-based regimen led to a “statistically significant and clinically meaningful” improvement in overall survival versus lenalidomide and rituximab plus placebo. The Adcetris combo also led to “positive outcomes” in various key secondary endpoints, including overall response rate and progression-free survival. In terms of safety, Adcetris’ tolerability and adverse event pro consistent with what had previously been established for the antibody-drug conjugate (ADC) in relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Roger Dansey, chief development officer of oncology at Pfizer, in a statement said that these data from ECHELON-3 indicate that Adcetris “could address an area of high unmet need in patients with relapsed or refractory DLBCL irrespective of CD30 expression.” “These results are particularly encouraging because the study evaluated heavily pre-treated patients, including some who received prior CAR-T therapy,” Dansey added. Originally developed by Seagen in collaboration with Takeda, Adcetris is an ADC that targets the CD30 surface protein, which is commonly expressed by certain blood cancers but not healthy cells. According to Seagen’s website, Adcetris carries a toxic payload called monomethyl auristatin E, which it releases inside the malignant cells triggering cell death. Pfizer secured access to Adcetris in March 2023, when it bought Seagen for $43 billion. Adcetris was first approved in August 2011 for the treatment of Hodgkin lymphoma and the rare systemic anaplastic large cell lymphoma. The ADC has since picked up several other approvals, allowing its use in other treatment settings and patient populations for these cancers. The pharma partners are continuing to develop Adcetris in other subtypes and stages of Hodgkin lymphoma, peripheral T-cell lymphoma, non-small cell lung cancer and melanoma. Tuesday’s readout will help Pfizer further deepen its expertise in ADC technology and expand its footprint in the space. Earlier this month, the pharma laid out its plans for its oncology franchise in the coming years. Key to its new strategy is a refined focus on four cancer types, which include hematologic malignancies such as lymphomas and multiple myeloma. Pfizer is also looking to build up its biologics business, which it expects to comprise approximately 65% of its cancer franchise by 2030, up from its current 6% mix. The Seagen acquisition, with its deep ADC portfolio, will contribute heavily to potentially meeting this target. Beyond Seagen, Pfizer in December 2023 also inked a potential $1.05 billion contract with Nona Biosciences to develop the Massachusetts-based biotech’s early-stage mesothelin-targeting ADC HBM9033 in solid tumors.

In 32 patients with relapsed/refractory (r/r) Hodgkin lymphoma (HL) treated at the recommended phase 2 dose level (RP2D), the objective response rate (ORR) was 97% and the complete response (CR) rate was 78%In this cohort median EFS was 9.8 months with 84% patients alive at 12 months, and median duration of response (DoR) was 8.8 monthsPatients were heavily pretreated (median of 7 prior lines), all had previously received CPIs and BV, and were refractory to their most recent line of therapyPatients received up to four cycles of therapy and the treatment was well tolerated with no instances of cytokine release syndrome (CRS), graft versus host disease (GvHD) or immune effector cell-associated neurotoxicity syndrome (ICANS) MANNHEIM, Germany, Dec. 11, 2023 (GLOBE NEWSWIRE) -- Affimed N.V. (Nasdaq: AFMD) (“Affimed” or the “Company”), a clinical-stage immuno-oncology company committed to giving patients back their innate ability to fight cancer, announced updated data on its lead innate cell engager (ICE®) acimtamig. Data from the investigator-initiated trial is being presented today at the American Society of Hematology (ASH) 2023 Annual Meeting by Yago Nieto, M.D., Ph.D., Professor of Stem Cell Transplantation and Cellular Therapy at The University of Texas MD Anderson Cancer Center and principal investigator of the study. Affimed will host a webcast following the presentation to review the data and provide a strategic update on acimtamig’s future development. A total of 42 patients were enrolled in the study with 36 patients treated at the RP2D. 32 of the 36 patients treated at the RP2D were HL patients. All 32 HL patients were heavily pretreated with multiple lines of chemotherapy, all had previously received CPIs and BV, and were refractory to their most recent line of therapy with active progressive disease at the time of enrollment. Across all dose levels, the treatment regimen achieved an ORR of 93% with a CR rate of 67%; among the 32 HL patients treated at the RP2D the treatment regimen achieved an ORR of 97% and a CR rate of 78%. In addition, the treatment regimen demonstrated a good safety and tolerability profile with no cases of CRS, ICANS or GvHD of any grade. Mild to moderate infusion related reactions (IRRs) were seen in 7.7% of the acimtamig infusions. Across all dose levels, median event free survival (EFS) was 8.8 months and median overall survival (OS) was not reached. For the HL patients treated at the RP2D, median EFS was 9.8 months - with 84% patients alive at 12 months. The median DoR was 8.8 months and 72% CR assessed at 6 months for HL patients treated at the RP2D; 30% of patients with complete response remained in CR beyond 12 months. “When we conduct studies in a patient population that has failed their previous line of therapy, demonstrating even a modest response is encouraging. To see this magnitude of responses in terms of ORR (97%) and CR (78%) is remarkable and fuels our commitment to bring this therapy to more patients,” said Dr. Andreas Harstrick, Chief Medical Officer at Affimed. “Building on these results, we are well underway with our Phase 2 LuminICE-203 study. We have enrolled and dosed patients in the first two cohorts and we look forward to sharing data in the first half of 2024.” The Company will host a call today at 1:30 p.m. PST / 4:30 p.m. EST / 22:30 CET to discuss the data presented at ASH and provide a strategic update. The conference call will be available via phone and webcast.

About the AFM13-104 Phase 1/2 Study The University of Texas MD Anderson Cancer Center is studying acimtamig (AFM13) in an investigator-sponsored phase 1/2 trial in combination with cord blood-derived allogeneic NK cells in patients with recurrent or refractory CD30-positive lymphomas. The study is a dose-escalation trial of precomplexed NK cells, followed by an expansion phase that recruited 36 patients with r/r CD30 positive lymphomas, treated with the RP2D of 1×108 NK cells/kg followed by three weekly doses of 200 mg acimtamig monotherapy. Each treatment cycle consists of lymphodepleting chemotherapy with fludarabine (30 mg/m² per day) and cyclophosphamide (300 mg/m² per day) followed two days later by a single infusion of cytokine-preactivated and expanded cord blood-derived NK cells that are pre-complexed with acimtamig. Three weekly infusions of acimtamig (200 mg) monotherapy are subsequently administered and responses are assessed by the investigator on day 28 by FDG-PET. MD Anderson has an institutional financial conflict of interest with Affimed related to this research and has therefore implemented an Institutional Conflict of Interest Management and Monitoring Plan. Additional information about the study can be found at www.clinicaltrials.gov (NCT04074746).
