Data from the QUASAR long-term extension study demonstrate more than 70% of patients were in clinical remission and more than 40% of patients were in endoscopic remission at Week 92 SAN DIEGO, Calif., May 5, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced new data from the TREMFYA® (guselkumab) Phase 3 QUASAR long-term extension (LTE) study in adults with moderately-to-severely active ulcerative colitis (UC). These data are among 24 abstracts highlighting the Company's research being presented at Digestive Disease Week (DDW) 2025. Data from the QUASAR LTE study demonstrate patients treated with TREMFYA® sustained clinical and endoscopic efficacy at Week 92: a, 1 72% of patients were in clinical remissionb with 99% of those patients remaining corticosteroid free for 8 or more weeks through Week 92. 43% of patients were in endoscopic remission.c Among patients achieving endoscopic improvementd at Week 44, 84% maintained endoscopic improvement through Week 92. Patients treated with TREMFYA® sustained clinical and endoscopic remission regardless of prior biologic and/or JAK inhibitor treatment history. "People living with ulcerative colitis seek treatments that both address the challenging symptoms of the disease and provide durable results," said Gary R. Lichtenstein, Vice Chief, Division of Gastroenterology and Hepatology, Development and Philanthropy at the University of Pennsylvania.e "These new data show TREMFYA delivers long-term, sustained clinical and endoscopic remission, marking important progress in UC care." Safety data were consistent with the well-established safety profile of TREMFYA® in inflammatory bowel disease (IBD) with no new safety concerns identified. "With these findings, TREMFYA shows the powerful impact it can have in achieving longer term remission in patients," said Esi Lamousé-Smith, MD, PhD, Vice President, Gastroenterology Disease Area Lead, Immunology, Johnson & Johnson Innovative Medicine. "This is a significant step forward in our mission to reshape the standard of care in inflammatory bowel disease." TREMFYA® is the first and only approved, dual-acting monoclonal antibody that blocks IL-23 while also binding to CD64, a receptor on cells that produce IL-23. IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including UC.2,3,4,5,6 TREMFYA® received FDA approval in September 2024 for the treatment of adult patients with moderately to severely active UC and is currently administered via an IV induction regimen, followed by a SC maintenance regimen. In November 2024, a supplemental Biologics License Application (sBLA) was submitted to the FDA seeking approval of a SC induction regimen of TREMFYA® for the treatment of adults with moderately to severely active UC. TREMFYA® was also approved by the FDA in March 2025 for SC and IV induction options for the treatment of adults with moderately to severely active Crohn's disease (CD). For a full list of all data being presented at DDW visit:   Editor's Notes: a. Nonresponder imputation results. Data were analyzed using 2 methods: 'nonresponder imputation' (NRI) accounting for patients with treatment failure or missing data, and 'as observed'. NRI results were consistent with as observed. b. Clinical remission was defined as a Mayo stool frequency subscore of 0 or 1 and not increased from induction baseline, a Mayo rectal bleeding subscore of 0, and a Mayo endoscopic subscore (MES) of 0 or 1. c. Endoscopic remission (normalization) was defined as a MES of 0. d. Endoscopic improvement was defined as a MES of 0 or 1. e. Dr. Lichtenstein has received honorarium for his role as a consultant to Johnson & Johnson. He has not been compensated for any media work. ABOUT THE QUASAR PROGRAM (NCT04033445) QUASAR is a randomized, double-blind, placebo-controlled, parallel group, multicenter, Phase 2b/3 program designed to evaluate the efficacy and safety of TREMFYA® in adults with moderately to severely active ulcerative colitis who had an inadequate response or intolerance to conventional therapy (e.g., thiopurines or corticosteroids), prior biologics (TNF antagonists or vedolizumab) and/or JAK inhibitors (tofacitinib). QUASAR included a Phase 2b dose-ranging induction study, a confirmatory Phase 3 induction study, and a Phase 3 randomized withdrawal maintenance study. In the Phase 3 induction study, patients received either TREMFYA® 200 mg or placebo by IV infusion at Weeks 0, 4, and 8. In the Phase 3 maintenance study, patients received a SC maintenance regimen of either TREMFYA® 200 mg q4w, TREMFYA® 100 mg q8w, or placebo.7 The ongoing long-term extension study provides an additional 4 years of treatment. Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points. ABOUT ULCERATIVE COLITIS Ulcerative colitis (UC) is a chronic disease of the large intestine, also known as the colon, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers, that produce pus and mucus. It is the result of the immune system's overactive response. Symptoms vary but may typically include loose and more urgent bowel movements, rectal bleeding or bloody stool, persistent diarrhea, abdominal pain, loss of appetite, weight loss, and fatigue.8 ABOUT TREMFYA® (guselkumab) Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human, dual-acting monoclonal antibody designed to neutralize inflammation at the cellular source by blocking IL-23 and binding to CD64 (a receptor on cells that produce IL-23). Findings for dual-acting are limited to in vitro studies that demonstrate guselkumab binds to CD64, which is expressed on the surface of IL-23 producing cells in an inflammatory monocyte model. The clinical significance of this finding is not known.

TREMFYA® subcutaneous induction demonstrates significant rates of clinical remission and endoscopic improvement at Week 24 in ulcerative colitis Findings build on recent FDA-approval of both routes of administration for induction therapy with TREMFYA® in Crohn's disease SAN DIEGO, May 5, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced new data from the Phase 3 ASTRO study evaluating TREMFYA® (guselkumab) subcutaneous (SC) induction therapy in adults with moderately to severely active ulcerative colitis (UC). The ASTRO Week 24 data build on the Week 12 SC induction data that showed statistically significant and clinically meaningful improvements compared to placebo across all clinical and endoscopic measures consistent with the U.S. Food and Drug Administration (FDA)-approved intravenous (IV) induction regimen evaluated in this population, in the Phase 3 QUASAR study.1,2 TREMFYA® is the first and only IL-23 inhibitor to demonstrate robust results with a fully SC regimen. These findings are among 24 abstracts highlighting the Company's research being presented at Digestive Disease Week (DDW) 2025. Data at Week 24 show patients treated with TREMFYA® 400 mg SC induction followed by SC maintenance dose regimens of either 100 mg every eight weeks (q8w) or 200 mg every four weeks (q4w) demonstrated statistically significant and clinically meaningful improvements across all clinical and endoscopic measures compared with patients receiving placebo.1 "Data from the ASTRO study demonstrate that subcutaneous induction treatment with TREMFYA provides clinically meaningful remission in patients with ulcerative colitis, similar to the effects seen with intravenous induction," said Millie Long, M.D., MPH, Professor of Gastroenterology and Hepatology at the University of North Carolina at Chapel Hill and study investigator.e "The availability of both subcutaneous and intravenous induction options would offer physicians and patients greater flexibility in their treatment approach." Furthermore, at Week 24, in prespecified analyses of subpopulations defined by prior advanced therapy treatment status, TREMFYA® demonstrated statistically significant results across endpoints in both biologic and JAK inhibitor-naïve and biologic and JAK inhibitor-refractory patients. Safety data from the ASTRO study were consistent with the well-established safety profile of TREMFYA®.1 "These results highlight the potential of TREMFYA to redefine ulcerative colitis care with a fully subcutaneous induction and maintenance regimen that offers a convenient option with meaningful clinical and endoscopic improvements," said Esi Lamousé-Smith, MD, PhD, Vice President, Gastroenterology Disease Area Lead, Immunology, Johnson & Johnson Innovative Medicine. "Our goal is to reshape UC care and empower prescribers with a differentiated and effective treatment that offers the option of patient self-administration from day one." TREMFYA® is the first and only approved, dual-acting monoclonal antibody that blocks IL-23 while also binding to CD64, a receptor on cells that produce IL-23. IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including UC.3,4,5,6,7 TREMFYA® received FDA approval in September 2024 for the treatment of adult patients with moderately to severely active UC and is currently administered via an IV induction regimen, followed by a SC maintenance regimen. In November 2024, a supplemental Biologics License Application (sBLA) was submitted to the FDA seeking approval of a SC induction regimen of TREMFYA® for the treatment of adults with moderately to severely active UC. TREMFYA® was also approved by the FDA in March 2025 for SC and IV induction options for the treatment of adults with moderately to severely active Crohn's disease (CD). For a full list of all data being presented at DDW visit: Editor's Notes: a. Clinical remission was defined as a Mayo stool frequency subscore of 0 or 1 and not increased from baseline, a Mayo rectal bleeding subscore of 0, and a Mayo endoscopic subscore of 0, or 1 with no friability present on the endoscopy. b. Symptomatic remission per Mayo score is defined as a stool frequency subscore of 0 (normal number of stools) or 1 (1 to 2 stools more than normal) and a rectal bleeding subscore of 0 (no blood seen). c. Endoscopic improvement was defined as an endoscopy subscore of 0 or 1 with no friability present on the endoscopy. d. Clinical response is defined as decrease from baseline in the modified Mayo score by greater than or equal to (>=) 30 percent (%) and >=2 points, with either a >=1-point decrease from baseline in the rectal bleeding subscore or a rectal bleeding subscore of 0 or 1. e.

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.

More information about the BRIUMVI Patient Support program can be accessed at www.briumvipatientsupport.com.ABOUT MULTIPLE SCLEROSIS Relapsing multiple sclerosis (RMS) is a chronic demyelinating disease of the central nervous system (CNS) and includes people with relapsing-remitting multiple sclerosis (RRMS) and people with secondary progressive multiple sclerosis (SPMS) who continue to experience relapses. RRMS is the most common form of multiple sclerosis (MS) and is characterized by episodes of new or worsening signs or symptoms (relapses) followed by periods of recovery. It is estimated that nearly 1 million people are living with MS in the United States and approximately 85% are initially diagnosed with RRMS.1,2 The majority of people who are diagnosed with RRMS will eventually transition to SPMS, in which they experience steadily worsening disability over time. Worldwide, more than 2.3 million people have a diagnosis of MS.1 ABOUT TG THERAPEUTICSTG Therapeutics is a fully integrated, commercial stage, biopharmaceutical company focused on the acquisition, development and commercialization of novel treatments for B-cell diseases.
