Biosimilar Cyltezo® demonstrates clinical equivalence to Humira® in patients with moderate-to-severe plaque psoriasis

RIDGEFIELD, Conn., Sept. 12, 2018 /PRNewswire/ -- Boehringer Ingelheim today announced results from a phase III study, confirming that Cyltezo^® is equivalent to Humira^®*, with no clinically meaningful differences in efficacy, safety and immunogenicity in people with moderate-to-severe chronic plaque psoriasis.¹ The 16-week data was presented at the European Association of Dermatology and Venereology Annual Meeting (EADV 2018) in Paris.

"This phase III study builds on recent evidence that demonstrates Cyltezo^® is equivalent to Humira^® for the treatment of moderately-to-severely active rheumatoid arthritis," said Key Tetzlaff, Vice President and Medical Head of Therapeutic Area Biosimilars at Boehringer Ingelheim. "These data reinforce the robust body of evidence that Boehringer Ingelheim is collecting to provide safe and effective treatment options that will contribute to the quality and sustainability of healthcare systems."

In the phase III study (NCT 02850965), 318 patients between 18 and 78 years of age with moderate-to-severe chronic plaque psoriasis, who had not previously received treatment with one or more biologic, were randomized to receive Cyltezo^® or Humira^® at 80 mg on day 1, 40 mg on day 7 and 40 mg every other week thereafter.

The primary endpoint, which measured the proportion of patients achieving a 75 percent reduction in PASI (Psoriasis Area and Severity Index) at week 16, was met. The 24-week data from this study are expected to be presented next year.

These clinical data in the psoriasis population continue to build on the strong existing analytical, pharmacological, non-clinical similarity data as well as the clinically similar data in the rheumatoid arthritis population, which were used to support the approval of Cyltezo^® by the U.S. Food and Drug Administration (FDA). In addition, Boehringer Ingelheim is conducting a clinical trial to demonstrate the interchangeability between Cyltezo^® and Humira^®. This is the first study in the U.S. to investigate an interchangeability designation for an adalimumab biosimilar.

Citrate-free Cyltezo^® is not commercially available in the U.S. at this time. Boehringer Ingelheim is currently engaged in patent litigation with AbbVie in the U.S.

Rheumatoid Arthritis: CYLTEZO is indicated, alone or in combination with methotrexate or other non-biologic disease-modifying anti-rheumatic drugs (DMARDs), for reducing signs and symptoms, inducing major clinical response, inhibiting the progression of structural damage, and improving physical function in adult patients with moderately to severely active rheumatoid arthritis. 

Juvenile Idiopathic Arthritis: CYLTEZO is indicated, alone or in combination with methotrexate, for reducing signs and symptoms of moderately to severely active polyarticular juvenile idiopathic arthritis in patients 4 years of age and older. 

Psoriatic Arthritis: CYLTEZO is indicated, alone or in combination with non-biologic DMARDs, for reducing signs and symptoms, inhibiting the progression of structural damage, and improving physical function in adult patients with active psoriatic arthritis.

Ankylosing Spondylitis: CYLTEZO is indicated for reducing signs and symptoms in adult patients with active ankylosing spondylitis.

Adult Crohn's Disease: CYLTEZO is indicated for reducing signs and symptoms and inducing and maintaining clinical remission in adult patients with moderately to severely active Crohn's disease who have had an inadequate response to conventional therapy, and reducing signs and symptoms and inducing clinical remission in these patients if they have also lost response to or are intolerant to infliximab.

Ulcerative Colitis: CYLTEZO is indicated for inducing and sustaining clinical remission in adult patients with moderately to severely active ulcerative colitis who have had an inadequate response to immunosuppressants such as corticosteroids, azathioprine or 6-mercaptopurine (6-MP). The effectiveness of CYLTEZO has not been established in patients who have lost response to or were intolerant to TNF blockers.

Plaque Psoriasis: CYLTEZO is indicated for the treatment of adult patients with moderate to severe chronic plaque psoriasis who are candidates for systemic therapy or phototherapy, and when other systemic therapies are medically less appropriate. CYLTEZO should only be administered to patients who will be closely monitored and have regular follow-up visits with a physician.

IMPORTANT SAFETY INFORMATION FOR CYLTEZO^®
WARNING: SERIOUS INFECTIONS and MALIGNANCY

SERIOUS INFECTIONS

Patients treated with adalimumab products, including CYLTEZO, are at increased risk for developing serious infections that may lead to hospitalization or death. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids.

Discontinue CYLTEZO if a patient develops a serious infection or sepsis.

Reported infections include:

• Active tuberculosis (TB), including reactivation of latent TB. Patients with TB have frequently presented with disseminated or extrapulmonary disease. Test patients for latent TB before CYLTEZO use and during therapy. Initiate treatment for latent TB prior to CYLTEZO use.

• Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Consider empiric anti-fungal therapy in patients at risk for invasive fungal infections who develop severe systemic illness.

• Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.

Carefully consider the risks and benefits of treatment with CYLTEZO prior to initiating therapy in patients: 1. with chronic or recurrent infection, 2. who have been exposed to TB, 3. with a history of opportunistic infection, 4. who resided in or traveled in regions where mycoses are endemic, 5. with underlying conditions that may predispose them to infection. Monitor patients closely for the development of signs and symptoms of infection during and after treatment with CYLTEZO, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. 

• Do not start CYLTEZO during an active infection, including localized infections.
• Patients older than 65 years, patients with co-morbid conditions, and/or patients taking concomitant immunosuppressants may be at greater risk of infection.
• If an infection develops, monitor carefully and initiate appropriate therapy.
• Drug interactions with biologic products: A higher rate of serious infections has been observed in RA patients treated with rituximab who received subsequent treatment with a TNF blocker. An increased risk of serious infections has been seen with the combination of TNF blockers with anakinra or abatacept, with no demonstrated added benefit in patients with RA. Concomitant administration of CYLTEZO with other biologic DMARDS (e.g., anakinra or abatacept) or other TNF blockers is not recommended based on the possible increased risk for infections and other potential pharmacological interactions.

MALIGNANCY

Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers including adalimumab products. Post-marketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including adalimumab products. These cases have had a very aggressive disease course and have been fatal. The majority of reported TNF blocker cases have occurred in patients with Crohn's disease or ulcerative colitis and the majority were in adolescent and young adult males. Almost all these patients had received treatment with azathioprine or 6-mercaptopurine (6-MP) concomitantly with a TNF blocker at or prior to diagnosis. It is uncertain whether the occurrence of HSTCL is related to use of a TNF blocker or a TNF blocker in combination with these other immunosuppressants.

• Consider the risks and benefits of TNF-blocker treatment prior to initiating or continuing therapy in a patient with known malignancy.
• In clinical trials of some TNF-blockers, including adalimumab products, more cases of malignancies were observed among TNF-blocker-treated patients compared to control patients.
• Non-melanoma skin cancer (NMSC) was reported during clinical trials for adalimumab-treated patients. Examine all patients, particularly those with a history of prolonged immunosuppressant or PUVA therapy, for the presence of NMSC prior to and during treatment with CYLTEZO.
• In adalimumab clinical trials, there was an approximate 3-fold higher rate of lymphoma than expected in the general U.S. population. Patients with chronic inflammatory diseases, particularly those with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at higher risk of lymphoma than the general population, even in the absence of TNF blockers.
• Postmarketing cases of acute and chronic leukemia were reported with TNF blocker use. Approximately half of the postmarketing cases of malignancies in children, adolescents, and young adults receiving TNF blockers were lymphomas; other cases included rare malignancies associated with immunosuppression and malignancies not usually observed in children and adolescents.

Hypersensitivity Reactions

• Anaphylaxis and angioneurotic edema have been reported following administration of adalimumab products. If a serious allergic reaction occurs, stop CYLTEZO and institute appropriate therapy.

Hepatitis B Virus Reactivation

• Use of TNF blockers, including CYLTEZO, may increase the risk of reactivation of hepatitis B virus (HBV) in patients who are chronic carriers. Some cases have been fatal. Evaluate patients at risk for HBV infection for prior evidence of HBV infection before initiating TNF blocker therapy. Exercise caution in patients who are carriers of HBV and monitor them during and after CYLTEZO treatment. Discontinue CYLTEZO and begin antiviral therapy in patients who develop HBV reactivation. Exercise caution when resuming CYLTEZO after HBV treatment.

Neurologic Reactions

• TNF blockers, including adalimumab products, have been associated with rare cases of new onset or exacerbation of central nervous system and peripheral demyelinating diseases, including multiple sclerosis, optic neuritis, and Guillain-Barré syndrome. Exercise caution when considering CYLTEZO for patients with these disorders; discontinuation of CYLTEZO should be considered if any of these disorders develop.

Hematological Reactions

• Rare reports of pancytopenia, including aplastic anemia, have been reported with TNF blockers. Medically significant cytopenia has been infrequently reported with adalimumab products. Consider stopping CYLTEZO if significant hematologic abnormalities occur.

Congestive Heart Failure

• Cases of worsening congestive heart failure (CHF) and new onset CHF have been reported with TNF blockers. Cases of worsening CHF have also been observed with adalimumab.  Exercise caution when using CYLTEZO in patients who have heart failure and monitor them carefully.

Autoimmunity

• Treatment with adalimumab products may result in the formation of autoantibodies and, rarely, in development of a lupus-like syndrome. Discontinue treatment if symptoms of a lupus-like syndrome develop.

Immunizations

• Patients on CYLTEZO should not receive live vaccines. Pediatric patients, if possible, should be brought up to date with all immunizations before initiating CYLTEZO therapy. The safety of administering live or live-attenuated vaccines in infants exposed to adalimumab products in utero is unknown. Risks and benefits should be considered prior to vaccinating (live or live-attenuated) exposed infants.

ADVERSE REACTIONS

• The most common adverse reactions in adalimumab clinical trials (>10%) were: infections (e.g., upper respiratory, sinusitis), injection site reactions, headache, and rash.
