TREMFYA® (guselkumab) studies underscore its potential to be the only IL-23 inhibitor to offer both subcutaneous and intravenous induction

TREMFYA® Phase 3 Crohn's disease study achieves all primary and secondary endpoints

SPRING HOUSE, Pa. (June 20, 2024) /PR Newswire/ – Johnson & Johnson (NYSE: JNJ) today announced positive topline results from the pivotal Phase 3 GRAVITI investigational study of TREMFYA® (guselkumab) subcutaneous (SC) induction therapy in adult patients with moderately to severely active Crohn's disease.¹ The study met both co-primary endpoints, achieving statistically significant and clinically meaningful outcomes for clinical remission at Week 12 as well as endoscopic response at Week 12. All remaining multiplicity-controlled endpoints at Week 12, Week 24 and Week 48 were statistically significant compared to placebo. GRAVITI adds to the robust results demonstrated in GALAXI 2 and GALAXI 3, the first-ever double-blind registrational head-to-head clinical trials to demonstrate superiority versus STELARA® (ustekinumab) in key endoscopic endpoints in Crohn's disease, which together show the potential of TREMFYA® to become the only IL-23 inhibitor to offer both SC or IV induction options.^3,4 Safety data from GRAVITI were consistent with the well-characterized safety profile of TREMFYA® in its approved indications.^2,a

“The Phase 3 GRAVITI study showed promising results with SC induction and provides similar clinical benefit to what was seen with IV induction in the GALAXI studies,” said David Lee, M.D., Ph.D., Global Therapeutic Area Head Immunology, Johnson & Johnson Innovative Medicine. “Having both SC and IV induction options provides choice and versatility for patients and providers. TREMFYA is poised to be the only IL-23 inhibitor to offer a full SC therapy for both induction and maintenance in Crohn's disease.”

Results from the GRAVITI study are being prepared for presentation at upcoming medical meetings and will be shared with health authorities in planned submissions. A separate Johnson & Johnson study evaluating the efficacy and safety of TREMFYA® SC induction therapy in ulcerative colitis is ongoing.  

Editor's Notes:

a. TREMFYA® is not approved for the treatment of ulcerative colitis or Crohn's disease.

ABOUT THE GRAVITI PROGRAM (NCT05197049)

GRAVITI is a randomized, double-blind, placebo-controlled Phase 3 study to evaluate guselkumab SC induction therapy (400 mg at Weeks 0, 4, and 8) in patients with moderately to severely active Crohn's disease who experienced an inadequate response or failed to tolerate conventional therapy (i.e., corticosteroids or immunomodulators) or biologic therapy (TNF antagonists or vedolizumab).¹ The maintenance doses in GRAVITI are the same as those evaluated in GALAXI (200 mg SC q4w and 100 mg SC q8w).¹ The study employed a treat-through design, in which patients are randomized to guselkumab at Week 0 and remain on that regimen throughout the study, regardless of clinical response status at the end of induction.¹ Participants randomized to placebo were able to receive guselkumab (400 mg SC q4w x3 ➔ 100 mg SC q8w) if rescue criteria were met at Week 16.¹

ABOUT THE GALAXI PROGRAM (NCT03466411)

GALAXI is a randomized, double-blind, placebo-controlled, active-controlled (ustekinumab), global, multicenter Phase 2/3 program designed to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active Crohn's disease with inadequate response/intolerance to conventional therapies (corticosteroids or immunomodulators) and/or biologics (TNF antagonists or vedolizumab).³ GALAXI includes a Phase 2 dose-ranging study (GALAXI 1) and two independent, identically designed confirmatory Phase 3 studies (GALAXI 2 and 3).³ Each GALAXI study employed a treat-through design in which participants remained on the treatment to which they were initially randomized and includes a long-term extension study that will assess clinical, endoscopic, and safety outcomes with guselkumab through a total of five years. Participants randomized to placebo were able to receive ustekinumab if clinical response was not met at Week 12.³

ABOUT CROHN'S DISEASE

Crohn's disease is one of the two main forms of inflammatory bowel disease, which affects an estimated three million Americans and an estimated four million people across Europe.^5,6 Crohn's disease is a chronic inflammatory condition of the gastrointestinal tract with no known cause, but the disease is associated with abnormalities of the immune system that could be triggered by a genetic predisposition, diet, or other environmental factors.⁷ Symptoms of Crohn's disease can vary, but often include abdominal pain and tenderness, frequent diarrhea, rectal bleeding, weight loss, and fever. Currently no cure is available for Crohn's disease.⁸

ABOUT TREMFYA® (guselkumab)

Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human, dual-acting monoclonal antibody that blocks IL-23 by binding to the p19 subunit of IL-23 and binding to CD64, a receptor on cells that produce IL-23.⁹ IL-23 is an important driver of the pathogenesis of inflammatory diseases.¹⁰ 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.^11,12,13,14

TREMFYA® is approved in the U.S.,⁹ Canada,¹⁵ Japan¹⁶ and a number of other countries for the treatment of adults with moderate-to-severe plaque psoriasis (PsO) who are candidates for injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light) and for the treatment of adult patients with active psoriatic arthritis (PsA).¹⁷ It is also approved in the EU for the treatment of moderate-to-severe plaque PsO in adults who are candidates for systemic therapy and for the treatment of active PsA in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.¹⁷

IMPORTANT SAFETY INFORMATION

STELARA® is a prescription medicine that affects your immune system. STELARA® can increase your chance of having serious side effects including:

Serious Infections

STELARA® may lower your ability to fight infections and may increase your risk of infections. While taking STELARA®, some people have serious infections, which may require hospitalization, including tuberculosis (TB), and infections caused by bacteria, fungi, or viruses. 

• Your doctor should check you for TB before starting STELARA® and watch you closely for signs and symptoms of TB during treatment with STELARA®. 
• If your doctor feels that you are at risk for TB, you may be treated for TB before and during treatment with STELARA®. 

You should not start taking STELARA® if you have any kind of infection unless your doctor says it is okay.

Before starting STELARA®, tell your doctor if you: 

• think you have an infection or have symptoms of an infection such as: 
• fever, sweats, or chills
• muscle aches
• cough
• shortness of breath
• blood in phlegm
• weight loss
• warm, red, or painful skin or sores on your body
• diarrhea or stomach pain
• burning when you urinate or urinate more often than normal
• feel very tired
• are being treated for an infection or have any open cuts. 
• get a lot of infections or have infections that keep coming back. 
• have TB, or have been in close contact with someone with TB. 

After starting STELARA®, call your doctor right away if you have any symptoms of an infection (see above). These may be signs of infections such as chest infections, or skin infections or shingles that could have serious complications. STELARA® can make you more likely to get infections or make an infection that you have worse. People who have a genetic problem where the body does not make any of the proteins interleukin 12 (IL‐12) and interleukin 23 (IL‐23) are at a higher risk for certain serious infections that can spread throughout the body and cause death. People who take STELARA® may also be more likely to get these infections.

Cancers

STELARA® may decrease the activity of your immune system and increase your risk for certain types of cancer. Tell your doctor if you have ever had any type of cancer. Some people who had risk factors for skin cancer developed certain types of skin cancers while receiving STELARA®. Tell your doctor if you have any new skin growths.

Posterior Reversible Encephalopathy Syndrome (PRES)

PRES is a rare condition that affects the brain and can cause death. The cause of PRES is not known. If PRES is found early and treated, most people recover. Tell your doctor right away if you have any new or worsening medical problems including: headache, seizures, confusion, and vision problems.

Serious Allergic Reactions

Serious allergic reactions can occur. Stop using STELARA® and get medical help right away if you have any symptoms of a serious allergic reaction such as: feeling faint, swelling of your face, eyelids, tongue, or throat, chest tightness, or skin rash.

Lung Inflammation

Cases of lung inflammation have happened in some people who receive STELARA® and may be serious. These lung problems may need to be treated in a hospital. Tell your doctor right away if you develop shortness of breath or a cough that doesn't go away during treatment with STELARA®.

Before receiving STELARA®, tell your doctor about all of your medical conditions, including if you: 

• have any of the conditions or symptoms listed above for serious infections, cancers, or PRES. 
• ever had an allergic reaction to STELARA® or any of its ingredients. Ask your doctor if you are not sure. 
• are allergic to latex. The needle cover on the prefilled syringe contains latex. 
• have recently received or are scheduled to receive an immunization (vaccine). People who take STELARA® should not receive live vaccines. Tell your doctor if anyone in your house needs a live vaccine. The viruses used in some types of live vaccines can spread to people with a weakened immune system, and can cause serious problems. You should not receive the BCG vaccine during the one year before receiving STELARA® or one year after you stop receiving STELARA®. 
• have any new or changing lesions within psoriasis areas or on normal skin. 
• are receiving or have received allergy shots, especially for serious allergic reactions. 
• receive or have received phototherapy for your psoriasis. 
• are pregnant or plan to become pregnant. It is not known if STELARA® can harm your unborn baby. You and your doctor should decide if you will receive STELARA® if you are breastfeeding or plan to breastfeed. It is thought that STELARA® passes into your breast milk. 
• talk to your doctor about the best way to feed your baby if you receive STELARA®.

Tell your doctor about all the medicines you take, including prescription and over‐the‐counter medicines, vitamins, and herbal supplements. Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

When prescribed STELARA®: 

• Use STELARA® exactly as your doctor tells you to. 
• STELARA® is intended for use under the guidance and supervision of your 
  doctor. In children 6 years and older, it is recommended that STELARA® be administered by a healthcare provider. If your doctor decides that you or a caregiver may give your injections of STELARA® at home, you should receive training on the right way to prepare and inject STELARA®. Your doctor will determine the right dose of STELARA® for you, the amount for each injection, and how often you should receive it. Do not try to inject STELARA® yourself until you or your caregiver have been shown how to inject STELARA® by your doctor or nurse. 

Common side effects of STELARA® include: nasal congestion, sore throat, and runny nose, upper respiratory infections, fever, headache, tiredness, itching, nausea and vomiting, redness at the injection site, vaginal yeast infections, urinary tract infections, sinus infection, bronchitis, diarrhea, stomach pain, and joint pain. These are not all of the possible side effects with STELARA®. Tell your doctor about any side effect that you experience. Ask your doctor or pharmacist for more information.
