ABOUT BRIUMVI® (ublituximab-xiiy) 150 mg/6 mL Injection for IVBRIUMVI is a novel monoclonal antibody that targets a unique epitope on CD20-expressing B-cells. Targeting CD20 using monoclonal antibodies has proven to be an important therapeutic approach for the management of autoimmune disorders, such as RMS. BRIUMVI is uniquely designed to lack certain sugar molecules normally expressed on the antibody. Removal of these sugar molecules, a process called glycoengineering, allows for efficient B-cell depletion at low doses. BRIUMVI is indicated in the U.S. for the treatment of adults with RMS, including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease and in the EU and UK for the treatment of adult patients with RMS with active disease defined by clinical or imaging features. A list of authorized specialty distributors can be found at www.briumvi.com. IMPORTANT SAFETY INFORMATIONContraindications: BRIUMVI is contraindicated in patients with: Active Hepatitis B Virus infection A history of life-threatening infusion reaction to BRIUMVI WARNINGS AND PRECAUTIONS Infusion Reactions: BRIUMVI can cause infusion reactions, which can include pyrexia, chills, headache, influenza-like illness, tachycardia, nausea, throat irritation, erythema, and an anaphylactic reaction. In MS clinical trials, the incidence of infusion reactions in BRIUMVI-treated patients who received infusion reaction-limiting premedication prior to each infusion was 48%, with the highest incidence within 24 hours of the first infusion. 0.6% of BRIUMVI-treated patients experienced infusion reactions that were serious, some requiring hospitalization. Observe treated patients for infusion reactions during the infusion and for at least one hour after the completion of the first two infusions unless infusion reaction and/or hypersensitivity has been observed in association with the current or any prior infusion. Inform patients that infusion reactions can occur up to 24 hours after the infusion. Administer the recommended pre-medication to reduce the frequency and severity of infusion reactions. If life-threatening, stop the infusion immediately, permanently discontinue BRIUMVI, and administer appropriate supportive treatment. Less severe infusion reactions may involve temporarily stopping the infusion, reducing the infusion rate, and/or administering symptomatic treatment. Infections: Serious, life-threatening or fatal, bacterial and viral infections have been reported in BRIUMVI-treated patients. In MS clinical trials, the overall rate of infections in BRIUMVI-treated patients was 56% compared to 54% in teriflunomide-treated patients. The rate of serious infections was 5% compared to 3% respectively. There were 3 infection-related deaths in BRIUMVI-treated patients. The most common infections in BRIUMVI-treated patients included upper respiratory tract infection (45%) and urinary tract infection (10%). Delay BRIUMVI administration in patients with an active infection until the infection is resolved. Consider the potential for increased immunosuppressive effects when initiating BRIUMVI after immunosuppressive therapy or initiating an immunosuppressive therapy after BRIUMVI. Hepatitis B Virus (HBV) Reactivation: HBV reactivation occurred in an MS patient treated with BRIUMVI in clinical trials. Fulminant hepatitis, hepatic failure, and death caused by HBV reactivation have occurred in patients treated with anti-CD20 antibodies. Perform HBV screening in all patients before initiation of treatment with BRIUMVI. Do not start treatment with BRIUMVI in patients with active HBV confirmed by positive results for HB surface antigen (HBsAg) and anti-HB tests. For patients who are negative for HBsAg and positive for HB core antibody [HBcAb+] or are carriers of HBV [HBsAg+], consult a liver disease expert before starting and during treatment. Progressive Multifocal Leukoencephalopathy (PML): Although no cases of PML have occurred in BRIUMVI-treated MS patients, JC virus infection resulting in PML has been observed in patients treated with other anti-CD20 antibodies and other MS therapies. If PML is suspected, withhold BRIUMVI and perform an appropriate diagnostic evaluation. Typical symptoms associated with PML are diverse, progress over days to weeks, and include progressive weakness on one side of the body or clumsiness of limbs, disturbance of vision, and changes in thinking, memory, and orientation leading to confusion and personality changes. MRI findings may be apparent before clinical signs or symptoms; monitoring for signs consistent with PML may be useful. Further investigate suspicious findings to allow for an early diagnosis of PML, if present. Following discontinuation of another MS medication associated with PML, lower PML-related mortality and morbidity have been reported in patients who were initially asymptomatic at diagnosis compared to patients who had characteristic clinical signs and symptoms at diagnosis. If PML is confirmed, treatment with BRIUMVI should be discontinued. Vaccinations: Administer all immunizations according to immunization guidelines: for live or live-attenuated vaccines, at least 4 weeks and, whenever possible, at least 2 weeks prior to initiation of BRIUMVI for non-live vaccines. BRIUMVI may interfere with the effectiveness of non-live vaccines. The safety of immunization with live or live-attenuated vaccines during or following administration of BRIUMVI has not been studied. Vaccination with live virus vaccines is not recommended during treatment and until B-cell repletion. Vaccination of Infants Born to Mothers Treated with BRIUMVI During Pregnancy: In infants of mothers exposed to BRIUMVI during pregnancy, assess B-cell counts prior to administration of live or live-attenuated vaccines as measured by CD19+ B-cells. Depletion of B-cells in these infants may increase the risks from live or live-attenuated vaccines. Inactivated or non-live vaccines may be administered prior to B-cell recovery. Assessment of vaccine immune responses, including consultation with a qualified specialist, should be considered to determine whether a protective immune response was mounted. Fetal Risk: Based on data from animal studies, BRIUMVI may cause fetal harm when administered to a pregnant woman. Transient peripheral B-cell depletion and lymphocytopenia have been reported in infants born to mothers exposed to other anti-CD20 B-cell depleting antibodies during pregnancy. A pregnancy test is recommended in females of reproductive potential prior to each infusion. Advise females of reproductive potential to use effective contraception during BRIUMVI treatment and for 6 months after the last dose. Reduction in Immunoglobulins: As expected with any B-cell depleting therapy, decreased immunoglobulin levels were observed. Decrease in immunoglobulin M (IgM) was reported in 0.6% of BRIUMVI-treated patients compared to none of the patients treated with teriflunomide in RMS clinical trials. Monitor the levels of quantitative serum immunoglobulins during treatment, especially in patients with opportunistic or recurrent infections, and after discontinuation of therapy, until B-cell repletion. Consider discontinuing BRIUMVI therapy if a patient with low immunoglobulins develops a serious opportunistic infection or recurrent infections, or if prolonged hypogammaglobulinemia requires treatment with intravenous immunoglobulins. Most Common Adverse Reactions: The most common adverse reactions in RMS trials (incidence of at least 10%) were infusion reactions and upper respiratory tract infections.

Châtillon, France, April 30, 2025 DBV Technologies Reports First Quarter 2025 Financial Results DBV Technologies (Euronext: DBV – ISIN: FR0010417345 – Nasdaq Stock Market: DBVT – CUSIP: 23306J309), a clinical-stage biopharmaceutical company, today reported financial results for the First Quarter of 2025. The quarterly and three months financial statements were approved by the Board of Directors on April 30, 2025. Financial Highlights for the First Quarter Ended March 31, 2025 The Company’s interim condensed consolidated financial statements for the three months ended March 31, 2025, are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). Cash and Cash Equivalents Our Condensed Consolidated Financial Statements have been prepared assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business. Cash and cash equivalents amounted to $13.0 million as of March 31, 2025, compared to $32.5 million as of December 31, 2024, a net decrease of $19.5 million. This decrease includes $19.7 million of cash used in operating activities, mainly in external clinical trial related expenses, notably progress on subject enrollment in the VITESSE Phase 3 clinical trial, as well as Regulatory and Manufacturing activities to support ongoing clinical trials. On March 27, 2025, the company announced a financing of up to $306.9 million (€284.5 million), to Advance Viaskin® Peanut Patch through Biologics License Application submission (BLA) and U.S. Commercial Launch, if approved. The financing included gross proceeds of $125.5 million (€116.3 million) received on April 7, 2025. With the receipt of the aforementioned proceeds, and based on its current operations, plans, and assumptions examined by the Board on March 23, 2025, the Company estimates that its cash and cash equivalents are sufficient to fund its operations into June 2026. The Company has incurred operating losses and negative cash flows from operations since inception. The Company does not generate product revenue and continues to prepare for the potential launch of its first product in the United States and in the European Union, if approved. These condensed consolidated financial statements do not include any adjustments to the carrying amounts and classification of assets, liabilities, and reported expenses that may be necessary if the Company was unable to continue as a going concern. Operating Income Operating income amounted to $0.8 million for the three months ended March 31, 2025, compared with $1.4 million for the same period in 2024 due to a lower French Research Tax Credit entitlement as a greater proportion of study activities were carried out in North America and are therefore not eligible for this tax credit. Operating Expenses Operating expenses amounted to $27.4 million for the three months ended March 31, 2025, compared with $30 million for the three months ended March 31, 2024, a decrease of $2.6 million. This decrease is primarily driven by lower General & Administrative expenses, notably $2.2 million expenses associated with office moves in France and the U.S that occurred in 2024. Net Loss and Net Loss Per Share The Company recorded a net loss of $27.1 million for the three months ended March 31, 2025, compared to a net loss of $27.3 million for the three months ended March 31, 2024. On a per share basis, net loss (based on the weighted average number of shares outstanding over the period) was $(0.26) for the three months ended March 31, 2025 vs. $(0.28) for the three months ended March 31, 2024.

TEPYLUTE® (thiotepa) Injection for Intravenous Use INDICATION TEPYLUTE is an alkylating drug indicated for the treatment of adenocarcinoma of the breast or ovary. IMPORTANT SAFETY INFORMATION WARNING: SEVERE MYELOSUPPRESSION and CARCINOGENICITY • TEPYLUTE may cause severe marrow suppression, and high doses may cause marrow ablation with resulting infection or bleeding. Monitor hematologic laboratory parameters. • TEPYLUTE should be considered potentially carcinogenic in humans. CONTRAINDICATIONS TEPYLUTE is contraindicated in patients with severe hypersensitivity to thiotepa and in concomitant use with live or attenuated vaccines. WARNINGS AND PRECAUTIONS Myelosuppression : For patients receiving TEPYLUTE for treatment of adenocarcinoma of the breast or adenocarcinoma of the ovary, if the bone marrow has been compromised by prior irradiation or chemotherapy, or is recovering from chemotherapy, the risk of severe myelosuppression with TEPYLUTE may be increased. Perform periodic complete blood counts during the course of treatment with TEPYLUTE. Provide supportive care for infections, bleeding, and symptomatic anemia. Inform patients of the possibility of developing low blood cell counts and the need for hematopoietic progenitor cell infusion. Instruct patients to immediately report to their healthcare provider if bleeding or fever occurs. Hypersensitivity: Clinically significant hypersensitivity reactions, including anaphylaxis, have occurred following administration of thiotepa. If anaphylactic or other clinically significant allergic reaction occurs, discontinue treatment with TEPYLUTE, initiate appropriate therapy, and monitor until signs and symptoms resolve. Counsel patients on the signs and symptoms of hypersensitivity and to seek immediate emergency assistance if they develop any of these signs and symptoms. Cutaneous Toxicity: TEPYLUTE and/or its active metabolites may be excreted in part via skin in patients receiving high-dose therapy. Treatment with TEPYLUTE may cause skin discoloration, pruritus, blistering, desquamation, and peeling that may be more severe in the groin, axillae, skin folds, in the neck area, and under dressings. Instruct patients to shower or bathe with water at least twice daily through 48 hours after administration of TEPYLUTE. Change the occlusive dressing and clean the covered skin at least twice daily through 48 hours after administration of TEPYLUTE. Change bed sheets daily during treatment. Skin reactions associated with accidental exposure to TEPYLUTE may occur. Wash the skin thoroughly with soap and water in case the TEPYLUTE solution contacts the skin. Flush mucous membranes in case of TEPYLUTE contact with mucous membranes. Concomitant Use of Live and Attenuated Vaccines: Do not administer live or attenuated viral or bacterial vaccines to a patient treated with TEPYLUTE until the immunosuppressive effects have resolved. Hepatic Veno-Occlusive Disease: Monitor by physical examination, serum transaminases, and bilirubin, and provide supportive care to patients who develop hepatic veno-occlusive disease. Central Nervous System Toxicity: Fatal encephalopathy has occurred in patients treated with high doses of thiotepa. Other central nervous system toxicities, such as headache, apathy, psychomotor retardation, disorientation, confusion, amnesia, hallucinations, drowsiness, somnolence, seizures, coma, inappropriate behavior, and forgetfulness have been reported to occur in a dose-dependent manner during or shortly after administration of high-dose thiotepa. Do not exceed the recommended dose of TEPYLUTE. If severe or life-threatening central nervous system toxicity occurs, discontinue administration of TEPYLUTE and provide supportive care. Carcinogenicity: Like many alkylating agents, thiotepa has been reported to be carcinogenic when administered to laboratory animals. Carcinogenicity is shown most clearly in studies using mice, but there is some evidence of carcinogenicity in man. There is an increased risk of secondary malignancy with the use of TEPYLUTE. Inform patients that TEPYLUTE can increase the risk of secondary malignancy. Polyethylene glycol (PEG) 400 toxicity : TEPYLUTE contains a high concentration of PEG 400. Based on findings in animals, administration of high amounts of PEG 400 may cause damage to the kidneys and liver at dosages higher than recommended. When prescribing TEPYLUTE, take into consideration the PEG 400 load from concomitant medications. Embryo-Fetal Toxicity: Based on the mechanism of action and findings in animals, TEPYLUTE can cause fetal harm when administered to a pregnant woman. There are no adequate and well-controlled studies of TEPYLUTE in pregnant women. Thiotepa given by the intraperitoneal (IP) route was teratogenic in mice at doses ≥1 mg/kg (3.2 mg/m 2 ), approximately 8-fold less than the maximum recommended human therapeutic dose (0.8 mg/kg, 27 mg/m 2 ), based on body-surface area. Thiotepa given by the IP route was teratogenic in rats at doses ≥3 mg/kg (21 mg/m 2 ), approximately equal to the maximum recommended human therapeutic dose, based on body-surface area. Thiotepa was lethal to rabbit fetuses at a dose of 3 mg/kg (41 mg/m 2 ), approximately two times the maximum recommended human therapeutic dose based on body-surface area. Advise pregnant women and females of reproductive potential of the potential risk to the fetus. Advise females of reproductive potential to use highly effective contraception during TEPYLUTE treatment and for 6 months after therapy/the last dose. Advise females of reproductive potential to inform their healthcare provider if they are pregnant or become pregnant. Advise males with female partners of reproductive potential to use effective contraception during TEPYLUTE treatment and for 1 year after therapy/the last dose. ADVERSE REACTIONS The most common adverse reactions (incidence greater than 10%) are neutropenia, anemia, thrombocytopenia, elevated alanine aminotransferase, elevated aspartate aminotransferase (AST), elevated bilirubin, mucositis, cytomegalovirus infection, hemorrhage, diarrhea, hematuria, and rash. The clinically significant adverse reactions include myelosuppression, infection, hypersensitivity, cutaneous toxicity, hepatic veno-occlusive disease, central nervous system toxicity, and carcinogenicity. DRUG INTERACTIONS Effect of Cytochrome CYP3A Inhibitors and Inducers: In vitro studies suggest that thiotepa is metabolized by CYP3A4 and CYP2B6 to its active metabolite triethylene phosphoramide (TEPA). Avoid coadministration of strong CYP3A4 inhibitors (e.g., itraconazole, clarithromycin, ritonavir) and strong CYP3A4 inducers (e.g., rifampin, phenytoin) with thiotepa due to the potential effects on efficacy and toxicity. Consider alternative medications with no or minimal potential to inhibit or induce CYP3A4. If concomitant use of strong CYP3A4 modulators cannot be avoided, closely monitor for adverse drug reactions. Effect of TEPYLUTE on Cytochrome CYP2B6 Substrates: In vitro studies suggest that thiotepa inhibits CYP2B6. Thiotepa may increase the exposure of drugs that are substrates of CYP2B6 in patients; however, the clinical relevance of this in vitro interaction is unknown. The administration of thiotepa with cyclophosphamide in patients reduces the conversion of cyclophosphamide to the active metabolite, 4‑hydroxycyclophosphamide; the effect appears sequence-dependent with a greater reduction in the conversion to 4-hydroxycyclophosphamide when thiotepa is administered 1.5 hours before the intravenous administration of cyclophosphamide compared to administration of thiotepa after intravenous cyclophosphamide. The reduction in 4-hydroxycyclophosphamide levels may potentially reduce the efficacy of cyclophosphamide treatment. USE IN SPECIFIC POPULATIONS Pregnancy: TEPYLUTE can cause fetal harm when administered to a pregnant woman based on findings from animals and the drug’s mechanism of action. Limited available data on thiotepa use in pregnant women are insufficient to inform a drug-associated risk of major birth defects and miscarriage. In animal reproduction studies, administration of thiotepa to pregnant mice and rats during organogenesis produced teratogenic effects (neural tube defects and malformations of the skeletal system of the fetus) at doses approximately 0.125 and 1 times, respectively, the maximum recommended human daily dose on a mg/m2 basis. Thiotepa was lethal to rabbit fetuses at approximately 2 times the maximum recommended human therapeutic dose based on body-surface area. Consider the benefits and risks of TEPYLUTE for the mother and possible risks to the fetus when prescribing TEPYLUTE to a pregnant woman. Lactation: There is no information regarding the presence of thiotepa in human milk, the effects on the breastfed infant, or the effects on milk production. Because of the potential for serious adverse reactions, including the potential for tumorigenicity shown for thiotepa in animal studies, advise patients not to breastfeed during TEPYLUTE treatment and for 1 week after therapy/the last dose. Females and Males of Reproductive Potential: TEPYLUTE can cause fetal harm when administered to a pregnant woman. Pregnancy Testing - Verify the pregnancy status of females of reproductive potential before initiating TEPYLUTE therapy. Contraception for Females - Advise females of reproductive potential to avoid pregnancy during TEPYLUTE treatment and for 6 months after therapy/the last dose. Advise females to immediately report pregnancy. Contraception for Males - TEPYLUTE may damage spermatozoa and testicular tissue, resulting in possible genetic abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during TEPYLUTE treatment and for 1 year after therapy/the last dose. Infertility - Based on nonclinical findings, male and female fertility may be compromised by treatment with TEPYLUTE. Advise patients that TEPYLUTE can produce infertility. Inform male patients about the possibility of sperm conservation before the start of therapy. Pediatric Use: Safety and effectiveness of TEPYLUTE in neonates have not been established. Safety and effectiveness of TEPYLUTE for the treatment of adenocarcinoma of the breast and adenocarcinoma of the ovary in pediatric patients have not been established. Geriatric Use: Clinical studies of thiotepa for treatment of adenocarcinoma of the breast and adenocarcinoma of the ovary did not include sufficient numbers of subjects aged 65 years and over to determine whether elderly subjects respond differently from younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreasing hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. Renal Impairment: In patients with moderate (creatinine clearance [CLcr] of 30 mL/min to 59 mL/min) renal impairment, decreased renal excretion may result in increased plasma levels of thiotepa and TEPA. This may result in increased toxicity. Monitor patients with moderate to severe (CLcr <30 mL/min) renal impairment for signs and symptoms of toxicity following treatment with TEPYLUTE for an extended period of time. Hepatic Impairment: Thiotepa is extensively metabolized in the liver. Patients with moderate (bilirubin levels greater than 1.5 times to 3 times the upper limit of normal and any AST) hepatic impairment may have increased plasma levels of thiotepa. This may result in toxicity. Monitor patients with moderate to severe (bilirubin levels greater than 3 times the upper limit of normal and any AST) hepatic impairment for signs and symptoms of toxicity following treatment with TEPYLUTE for an extended period of time.
