NEW PHASE 3 DATA SHOW SINGLE DOSE OF STELARA® (USTEKINUMAB) INDUCES CLINICAL REMISSION AND RESPONSE IN ADULTS WITH MODERATE TO SEVERE ULCERATIVE COLITIS

Janssen presents 8-week induction data from pivotal Phase 3 UNIFI study during plenary session at the American College of Gastroenterology Annual Scientific Meeting 2018

PHILADELPHIA, PENNSYLVANIA, October 9, 2018 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new data showing treatment with a single intravenous (IV) dose of STELARA^® (ustekinumab) induces clinical remission and response in adults with moderate to severe ulcerative colitis (UC) who previously experienced an inadequate response or were intolerant to conventional or biologic therapies. The findings will be presented today at 2:00 pm EDT as part of the Late Breaking Abstract Plenary at the American College of Gastroenterology (ACG) Scientific Meeting 2018.

Results from the induction phase of the Phase 3 UNIFI study show that treatment with a single IV dose of STELARA induced clinical remission in a significantly greater proportion of UC patients at week 8, compared with placebo, at both doses studied. Major secondary endpoints including the proportion of patients in clinical response, endoscopic healing, as well as improvement in health-related quality of life, were also significantly higher at week 8 among patients receiving STELARA compared with patients receiving placebo. About 50 percent of study participants are considered biologic refractory, and 17 percent have a history of inadequate response or intolerance to an anti-TNF and/or Entyvio* (vedolizumab).

“Ulcerative colitis is a complex immune disease, and more than half of UC patients have not experienced remission with currently available conventional or biologic treatment options,” said lead investigator Bruce E. Sands, MD, Dr. Burrill B. Crohn Professor of Medicine and Chief of the Dr. Henry D. Janowitz Division of Gastroenterology at the Icahn School of Medicine at Mount Sinai. “The significant rates of remission observed through the 8-week induction, coupled with a safety profile that is well-documented through years of research and use in other immune diseases, demonstrate the potential for ustekinumab as an effective treatment for UC.”

Patients participating in the Phase 3 UNIFI study were randomized 1:1:1 at week 0 and received a single IV dose of placebo, STELARA 130 mg, or STELARA ~6 mg/kg (weight tiered dosing: patients weighing less than or equal to 55 kg received 260 mg; patients weighing more than 55 kg and less than or equal to 85 kg received 390 mg; and patients weighing more than 85 kg received 520 mg). At week 8, patients (n=961) were evaluated for clinical remission, endoscopic healing, clinical response, change from baseline in the IBDQ score, and mucosal healing (an endpoint that includes both endoscopic healing and histologic healing).

At week 8:

• 15.6 percent of patients receiving STELARA 130 mg and 15.5 percent of patients receiving STELARA ~6 mg/kg achieved clinical remission compared with 5.3 percent of patients receiving placebo (p < 0.001). Remission was defined as a Mayo score ≤2 points, with no individual subscore >1.

• 26.3 percent of patients receiving STELARA 130 mg and 27 percent of patients receiving STELARA ~6 mg/kg experienced endoscopic healing compared with 13.8 percent of patient receiving placebo (p<0.001). Endoscopic healing was defined as a Mayo endoscopy subscore of 0 (normal mucosa or inactive disease) or 1 (mild disease activity).

• 51.3 percent and 61.8 percent of patients receiving STELARA 130 mg and STELARA ~6 mg/kg achieved clinical response compared with 31.3 percent of patients receiving placebo (p < 0.001). Clinical response was defined as a decrease from baseline in the Mayo score by ≥30% and ≥3 points, with either a decrease from baseline in the rectal bleeding subscore ≥1 or a rectal bleeding subscore of 0 or 1.

• 20.3 percent and 18.4 percent of patients receiving STELARA 130 mg and STELARA ~6 mg/kg achieved mucosal healing compared with 8.9 percent of patients receiving placebo (p < 0.001). Mucosal healing is defined as combined endoscopic healing (Mayo endoscopy subscore of 0 or 1) and histologic healing (defined as 0-<5% neutrophils in epithelium, no crypt destruction, and no erosions or ulcerations or granulations).

In addition, both doses of STELARA resulted in statistically significant improvements in the Inflammatory Bowel Disease Questionnaire (IBDQ), a health-related quality of life measure for patients with IBD, as well as markers of inflammation, including C-reactive protein (CRP), fecal lactoferrin and calprotectin.

Through week 8, adverse events (AEs), serious AEs and infections (including serious infections) were reported in similar proportions across STELARA and placebo treatment groups. No malignancies, opportunistic infections or tuberculosis were reported through week 8. One death from an esophageal varices hemorrhage was reported for a patient with no known history of cirrhosis or portal hypertension in the ~6mg/kg dose group prior to week 8.

“STELARA is the first biologic approved for any indication that targets interleukin (IL)-12 and IL-23 cytokines, which are believed to play a role in immune-mediated diseases, like ulcerative colitis,” said Philippe Szapary, MD, MSCE, Vice President, Clinical Development, Janssen Research & Development, LLC. “These induction data from the Phase 3 UNIFI study underscore the potential for this pathway in the treatment of UC, which may lead to a new effective and safe treatment option for UC patients in the future.”

In addition to the UNIFI study data, Janssen is also presenting results from the IM-UNITI open label long-term extension (LTE) for STELARA in the treatment of adults with moderate to severe Crohn’s disease, including an oral presentation on long-term efficacy of STELARA with and without concomitant immunosuppressants through 2 years. A poster demonstrating the long-term efficacy and safety of STELARA through 3 years of treatment will also be presented.

About the UNIFI Trial

UNIFI is a Phase 3 protocol designed to evaluate the safety and efficacy of STELARA induction and maintenance dosing for the treatment of moderate to severe ulcerative colitis in adults who demonstrated an inadequate response to or were unable to tolerate conventional (i.e., corticosteroids, immunomodulators) or biologic (i.e., one or more TNF blockers or vedolizumab) therapies. Both the induction and maintenance studies are randomized, double-blind, placebo-controlled, parallel group, multi-center studies The Induction study was of at least 8 weeks duration for each participant. Participants achieving clinical response in the Induction study were eligible for the Maintenance study. The Maintenance study was 44 weeks duration. The primary endpoint of the induction study is clinical remission at week 8 and the primary endpoint for the maintenance study is clinical remission at week 44 among responders to a single IV STELARA infusion.

After completion of the maintenance study, a long-term extension will follow eligible participants for an additional 3 years.

About Ulcerative Colitis

More than five million people worldwide are living with Crohn’s disease and ulcerative colitis—collectively known as IBD. Ulcerative colitis, or UC, affects nearly 907,000 people in the United States, with approximately 38,000 new cases diagnosed each year.¹ 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 mucous. It is the result of an abnormal response by your body’s immune system. Symptoms vary but may include loose and more urgent bowel movements, persistent diarrhea, abdominal pain, bloody stool, loss of appetite, weight loss and fatigue.²

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
• 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). 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.

Reversible posterior leukoencephalopathy syndrome (RPLS)

RPLS is a rare condition that affects the brain and can cause death. The cause of RPLS is not known. If RPLS 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 RPLS.
• 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^®.
• 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.
• STELARA^® is intended for use under the guidance and supervision of your doctor. In children 12 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: upper respiratory infections, headache, and tiredness in psoriasis patients; joint pain and nausea in psoriatic arthritis patients; and upper respiratory infections, redness at the injection site, vaginal yeast infections, itching, urinary tract infections, and vomiting in Crohn’s disease patients. 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.

Please read the Full Prescribing Information, including the Medication Guide for STELARA^®, and discuss any questions you have with your doctor.
