"Joining BioNTech is a privilege, especially during this decisive phase in which we aim to capitalize on our innovative pipeline with clear strategic focus. While we continue to significantly invest into the execution of our strategy, our commitment to operational and financial discipline is starting to show tangible results," said Ramón Zapata, Chief Financial Officer at BioNTech. "With the strategic BMS collaboration we will further strengthen our topline and cash position. As such, we will receive an upfront cash-payment of $1.5 billion in Q3 that we anticipate to be recognized as revenue over the development phase of BNT327."

Anticipated Financial Effect4 of the BMS Partnership

As part of the agreement with BMS, BioNTech expects to receive $1.5 billion in an upfront cash payment this year, and for this payment to be reflected in the Company’s reported cash position as of the third quarter 2025. BioNTech also expects to receive $2.0 billion in total non-contingent anniversary cash payments from 2026 through 2028. The upfront and non-contingent cash payments, amounting to $3.5 billion, are expected to be recognized as revenues over the development phase of BNT327.

In addition, BioNTech will be eligible to receive up to $7.6 billion in development, regulatory and commercial milestones, with the majority of milestone payments expected to be triggered upon approvals and during commercialization. All milestones payments are anticipated to be reflected in the Company’s cash position and to be recognized as revenues following milestone achievement.

Under the agreement, BioNTech and BMS will share joint development and manufacturing costs of BNT327 on a 50:50 basis, subject to certain exceptions. Global profits and losses will be equally shared between BioNTech and BMS.

2025 Financial Year Guidance Reaffirmed5:

Revenues for the 2025 financial year €1,700 million – €2,200 million

BioNTech expects its revenues for the full 2025 financial year to be in the range of €1,700 – €2,200 million and revenue phasing primarily concentrated in the last three to four months, driving the full year revenue figure. The revenue guidance assumes: relatively stable pricing and market share as compared to 2024; inventory write-downs and other charges estimated to be approximately 15% of BioNTech’s share of gross profit from COVID-19 vaccines sales in Pfizer Inc.’s ("Pfizer") territory; anticipated revenues from a pandemic preparedness contract with the German government, from collaborations and from the BioNTech Group service businesses. Current and potential further developments in law, public policy, international trade, and public sentiment as they continue to evolve could further negatively impact the anticipated COVID-19 vaccine revenues and expenses.

Planned 2025 Financial Year Expenses and Capex

R&D expenses €2,600 million – €2,800 million
SG&A expenses €650 million – €750 million
Capital expenditures for operating activities €250 million – €350 million

BioNTech expects to continuously focus investments on R&D and scaling the business for late-stage development and commercial readiness in oncology, while remaining cost-disciplined. Strategic capital allocation will continue to be a key driver of the Company’s trajectory. As part of BioNTech’s strategy, the Company may continue to evaluate appropriate corporate development opportunities with the aim of driving sustainable long-term growth and create future value.

"While initial therapy for MZL can be effective, multiple relapses over the course of several years are common, leaving patients in need of a new treatment option that can provide high, lasting response rates," said Rosanna Ricafort, vice president, Senior Global Program Lead for Hematology and Cell Therapy, Bristol Myers Squibb. "This FDA acceptance brings us one step closer to potentially standardizing CAR T cell therapy as a treatment option for MZL, while building on our commitment to bring this personalized therapy to as many eligible patients as possible."

The application is based on results from the primary analysis of the MZL cohort in TRANSCEND FL, an open-label, multicenter, Phase 2, single-arm study, which was shared in an oral presentation during the 2025 International Conference on Malignant Lymphoma (ICML) in June 2025.

The development progress of Breyanzi reflects BMS’ continued efforts to collaborate across the healthcare ecosystem, with the ultimate goal of reaching more patients and democratizing access to cell therapy. Recently, the FDA approved streamlined patient monitoring requirements and the removal of the REMS program for Breyanzi, easing known barriers to treatment and administration while maintaining patient safety.

About TRANSCEND FL
TRANSCEND FL (NCT04245839) is an open-label, global, multicenter, Phase 2, single-arm study to determine the efficacy and safety of Breyanzi in patients with relapsed or refractory indolent B-cell non-Hodgkin lymphoma, including follicular lymphoma and marginal zone lymphoma. The primary outcome measure is overall response rate. Secondary outcome measures include complete response rate, duration of response, and progression-free survival.

About MZL
Marginal zone lymphoma (MZL) is the third most common lymphoma, accounting for about 7% of all non-Hodgkin lymphoma cases. Most patients with MZL are at a median age of 67 years when they are diagnosed. MZL develops when white blood cells cluster together to form lumps in a person’s lymph nodes or organs. Initial therapy often leads to remission, but relapse is common, sometimes occurring several times over many years. A small portion of MZL cases transform into diffuse large-B-cell lymphoma, a more aggressive lymphoma.

About Breyanzi
Breyanzi is a CD19-directed CAR T cell therapy with a 4-1BB costimulatory domain, which enhances the expansion and persistence of the CAR T cells. Breyanzi is made from a patient’s own T cells, which are collected and genetically reengineered to become CAR T cells that are then delivered via infusion as a one-time treatment. The treatment process includes blood collection, CAR T-cell creation, potential bridging therapy, lymphodepletion, administration, and side-effect monitoring.

Breyanzi is approved in the U.S. for the treatment of relapsed or refractory large B-cell lymphoma (LBCL) after at least one prior line of therapy, has received accelerated approval for the treatment of relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) after at least two prior lines of therapy and relapsed or refractory follicular lymphoma (FL) in the third-line plus setting, and is approved for the treatment of relapsed or refractory mantle cell lymphoma (MCL) in the third-line plus setting. Breyanzi is also approved in Japan, the European Union (EU), Switzerland, the United Kingdom, and Canada for the treatment of relapsed or refractory LBCL after at least one prior line of therapy; in Japan for the treatment of patients with relapsed or refractory high-risk FL after one prior line of systemic therapy, and in patients with relapsed or refractory FL after two or more lines of systemic therapy; and in the EU for the treatment of relapsed or refractory FL after two or more lines of systemic therapy.

Bristol Myers Squibb’s clinical development program for Breyanzi includes clinical studies in several types of lymphoma. For more information, visit clinicaltrials.gov.

Breyanzi U.S. Important Safety Information

WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES, AND SECONDARY HEMATOLOGICAL MALIGNANCIES

Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving BREYANZI. Do not administer BREYANZI to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab with or without corticosteroids.
Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving BREYANZI, including concurrently with CRS, after CRS resolution, or in the absence of CRS. Monitor for neurologic events after treatment with BREYANZI. Provide supportive care and/or corticosteroids as needed.
T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including BREYANZI.
Cytokine Release Syndrome

Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred following treatment with BREYANZI. In clinical trials of BREYANZI, which enrolled a total of 702 patients with non-Hodgkin lymphoma (NHL), CRS occurred in 54% of patients, including ≥ Grade 3 CRS in 3.2% of patients. The median time to onset was 5 days (range: 1 to 63 days). CRS resolved in 98% of patients with a median duration of 5 days (range: 1 to 37 days). One patient had fatal CRS and 5 patients had ongoing CRS at the time of death. The most common manifestations of CRS (≥10%) were fever, hypotension, tachycardia, chills, hypoxia, and headache.

Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), cardiac arrest, cardiac failure, diffuse alveolar damage, renal insufficiency, capillary leak syndrome, hypotension, hypoxia, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS).

Ensure that 2 doses of tocilizumab are available prior to infusion of BREYANZI.

Neurologic Toxicities

Neurologic toxicities that were fatal or life-threatening, including immune effector cell-associated neurotoxicity syndrome (ICANS), occurred following treatment with BREYANZI. Serious events including cerebral edema and seizures occurred with BREYANZI. Fatal and serious cases of leukoencephalopathy, some attributable to fludarabine, also occurred.

In clinical trials of BREYANZI, CAR T cell-associated neurologic toxicities occurred in 31% of patients, including ≥ Grade 3 cases in 10% of patients. The median time to onset of neurotoxicity was 8 days (range: 1 to 63 days). Neurologic toxicities resolved in 88% of patients with a median duration of 7 days (range: 1 to 119 days). Of patients developing neurotoxicity, 82% also developed CRS.

The most common neurologic toxicities (≥5%) included encephalopathy, tremor, aphasia, headache, dizziness, and delirium.

CRS and Neurologic Toxicities Monitoring

Monitor patients daily for at least 7 days following BREYANZI infusion for signs and symptoms of CRS and neurologic toxicities and assess for other causes of neurological symptoms. Continue to monitor patients for signs and symptoms of CRS and neurologic toxicities for at least 2 weeks after infusion and treat promptly. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated. Manage neurologic toxicity with supportive care and/or corticosteroid as needed. Advise patients to avoid driving for at least 2 weeks following infusion. Counsel patients to seek immediate medical attention should signs or symptoms of CRS or neurologic toxicity occur at any time.

Hypersensitivity Reactions

Allergic reactions may occur with the infusion of BREYANZI. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO).

Serious Infections

Severe infections, including life-threatening or fatal infections, have occurred in patients after BREYANZI infusion. In clinical trials of BREYANZI, infections of any grade occurred in 34% of patients, with Grade 3 or higher infections occurring in 12% of all patients. Grade 3 or higher infections with an unspecified pathogen occurred in 7%, bacterial infections in 3.7%, viral infections in 2%, and fungal infections in 0.7% of patients. One patient who received 4 prior lines of therapy developed a fatal case of John Cunningham (JC) virus progressive multifocal leukoencephalopathy 4 months after treatment with BREYANZI. One patient who received 3 prior lines of therapy developed a fatal case of cryptococcal meningoencephalitis 35 days after treatment with BREYANZI.

Febrile neutropenia developed after BREYANZI infusion in 8% of patients. Febrile neutropenia may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad- spectrum antibiotics, fluids, and other supportive care as medically indicated.

Monitor patients for signs and symptoms of infection before and after BREYANZI administration and treat appropriately. Administer prophylactic antimicrobials according to standard institutional guidelines. Avoid administration of BREYANZI in patients with clinically significant, active systemic infections.

Viral reactivation: Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells. In clinical trials of BREYANZI, 35 of 38 patients with a prior history of HBV were treated with concurrent antiviral suppressive therapy. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing. In patients with prior history of HBV, consider concurrent antiviral suppressive therapy to prevent HBV reactivation per standard guidelines. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing. In patients with prior history of HBV, consider concurrent antiviral suppressive therapy to prevent HBV reactivation per standard guidelines.

Prolonged Cytopenias

Patients may exhibit cytopenias not resolved for several weeks following lymphodepleting chemotherapy and BREYANZI infusion. In clinical trials of BREYANZI, Grade 3 or higher cytopenias persisted at Day 29 following BREYANZI infusion in 35% of patients, and included thrombocytopenia in 25%, neutropenia in 22%, and anemia in 6% of patients. Monitor complete blood counts prior to and after BREYANZI administration.

Hypogammaglobulinemia

B-cell aplasia and hypogammaglobulinemia can occur in patients receiving BREYANZI. In clinical trials of BREYANZI, hypogammaglobulinemia was reported as an adverse reaction in 10% of patients. Hypogammaglobulinemia, either as an adverse reaction or laboratory IgG level below 500 mg/dL after infusion, was reported in 30% of patients. Monitor immunoglobulin levels after treatment with BREYANZI and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement as clinically indicated.

Live vaccines: The safety of immunization with live viral vaccines during or following BREYANZI treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during BREYANZI treatment, and until immune recovery following treatment with BREYANZI.

Secondary Malignancies

Patients treated with BREYANZI may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including BREYANZI. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes. Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Bristol Myers Squibb at 1-888-805-4555 for reporting and to obtain instructions on collection of patient samples for testing.

Immune Effector Cell-Associated Hemophagocytic Lymphohistiocytosis-Like Syndrome (IEC-HS)

Immune Effector Cell-Associated Hemophagocytic Lymphohistiocytosis-Like Syndrome (IEC-HS), including fatal or life-threatening reactions, occurred following treatment with BREYANZI. Three of 89 (3%) safety evaluable patients with R/R CLL/SLL developed IEC-HS. Time to onset of IEC-HS ranged from 7 to 18 days. Two of the 3 patients developed IEC-HS in the setting of ongoing CRS and 1 in the setting of ongoing neurotoxicity. IEC-HS was fatal in 2 of 3 patients. One patient had fatal IEC-HS and one had ongoing IEC-HS at time of death. IEC-HS is a life-threatening condition with a high mortality rate if not recognized and treated early. Treatment of IEC-HS should be administered per current practice guidelines.

Adverse Reactions

The most common adverse reaction(s) (incidence ≥30%) in:

LBCL are fever, cytokine release syndrome, fatigue, musculoskeletal pain, and nausea. The most common Grade 3-4 laboratory abnormalities include lymphocyte count decrease, neutrophil count decrease, platelet count decrease, and hemoglobin decrease.
CLL/SLL are cytokine release syndrome, encephalopathy, fatigue, musculoskeletal pain, nausea, edema, and diarrhea. The most common Grade 3-4 laboratory abnormalities include neutrophil count decrease, white blood cell decrease, hemoglobin decrease, platelet count decrease, and lymphocyte count decrease.
FL is cytokine release syndrome. The most common Grade 3-4 laboratory abnormalities include lymphocyte count decrease, neutrophil count decrease, and white blood cell decrease.
MCL are cytokine release syndrome, fatigue, musculoskeletal pain, and encephalopathy. The most common Grade 3-4 laboratory abnormalities include neutrophil count decrease, white blood cell decrease, and platelet count decrease.

This open-label, multi-center international study plans to enroll 66 patients with proficient mismatch repair (pMMR) or non-microsatellite instability-high (non-MSI-H) mCRC to evaluate the safety and preliminary efficacy of the triplet therapy. Enrollment is planned in Taiwan and Australia. Tislelizumab, a PD-1 monoclonal antibody, used in this trial is provided by BeOne Medicines (formerly known as BeiGene). Further details on this collaboration were disclosed by Anbogen in a press release dated September 27, 2024.

ABT-301 is an oral HDAC1/2/3 inhibitor. Preclinical studies have shown that it promotes CD8+ cytotoxic T cell infiltration and activity, enhances antigen presentation, and inhibits M-MDSCs cells, effectively modulating the tumor microenvironment and converting "cold tumors" into "hot tumors" to improve the efficacy of immune checkpoint inhibitors. ABT-301 also exhibits pro-apoptotic, anti-angiogenic, and tumor metabolic regulation effects. As a single-molecule, multi-modality anti-cancer agent, ABT-301 aims to enhance tumor treatment when combined with the two antibody drugs.

Notably, in a previous Phase 1 monotherapy clinical trial involving 23 participants, ABT-301 did not exhibit neutropenia or cardiac toxicity, which are commonly observed in other HDAC inhibitors—further supporting its suitability for use in combination immunotherapy.

Approximately 95% of mCRC patients are pMMR or non-MSI-H types—commonly referred to as "cold tumors"—which respond poorly to current immunotherapies. Only around 5% of patients with deficient mismatch repair (dMMR) or microsatellite instability-high (MSI-H) "hot tumors" typically benefit from immune checkpoint inhibitors. According to GlobalData, an estimated 370,000 new pMMR/non-MSI-H patients in second-line or later settings are diagnosed annually across the U.S., China, Japan, and the top five European markets (UK, France, Germany, Spain, and Italy), representing a potential market size of USD $9 billion.

Anbogen stated that the FDA’s IND approval marks a key milestone in the development of ABT-301, demonstrating the safety profile of the triplet therapy and advancing it into clinical stages. The company emphasized that the study targets the majority of patients (over 90%) with poor responses to immunotherapy, aiming to provide a novel treatment option and address this unmet clinical need.

Looking ahead, Anbogen will continue to advance the clinical development of ABT-301 while pursuing global licensing and strategic partnerships to accelerate commercialization and market entry. The company is also launching its Series B fundraising to attract strategic partners committed to advancing innovative cancer therapies and global expansion.
