Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has approved a subcutaneous (SC) formulation of Actemra ® (tocilizumab) for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have used one or more disease-modifying antirheumatic drugs (DMARDs), such as methotrexate (MTX), that did not provide enough relief. Like the intravenous (IV) formulation, the SC formulation can be used both as a single-agent therapy and in combination with MTX or other non-biologic DMARDs. The Actemra pre-filled syringe (PFS) injection formulation will be available in November. “People with moderately to severely active rheumatoid arthritis can suffer irreversible joint damage that may be prevented by earlier treatment with a medicine such as Actemra,” said Hal Barron, M.D., chief medical officer and head, Global Product Development. “We're pleased that these patients will now have the option of Actemra as a subcutaneous injection or an IV infusion.” Actemra, originally approved by the FDA as an IV medicine in 2010, is the first and only humanized interleukin-6 (IL-6) receptor-antagonist monoclonal antibody approved by the FDA for both SC and IV administration. “Because some patients prefer a subcutaneous injection, it is important for physicians to have this new option,” said Alan J. Kivitz, M.D., FACR, President of Altoona Center for Clinical Research, Duncansville, Pa. 1 “In clinical trials, Actemra was shown to be effective and have a consistent safety profile – with the exception of injection site reactions for the subcutaneous formulation – when administered either intravenously or subcutaneously and may be used with or without methotrexate.” The approval is based on data from the Phase III clinical trials SUMMACTA and BREVACTA. For Actemra SC, the FDA recommended dosage is 162 mg administered subcutaneously every other week, followed by an increase to 162 mg every week based on clinical response for patients less than 100 kg (220 lbs) in weight. For patients at or above 100 kg (220 lbs), the dosing is 162 mg administered subcutaneously every week.
About SUMMACTASUMMACTA is a randomized, double-blind, active-controlled, parallel-group, multicenter study with a double-blind period of 24 weeks in 1,262 patients with moderately to severely active RA. SUMMACTA demonstrated comparable efficacy (non-inferiority) of the SC formulation of Actemra 162 mg given weekly plus DMARDs compared to 8 mg/kg of Actemra given intravenously every four weeks plus DMARDs in patients with moderately to severely active RA in the DMARD-IR population (20 percent of whom had inadequate response to anti-tumor necrosis factor [anti-TNF] therapy). A similar proportion of RA patients in each group experienced at least a 20 percent improvement in tender and swollen joints (American College of Rheumatology [ACR] 20 response) at Week 24 (69 percent with Actemra SC formulation vs. 73 percent with Actemra IV). Analysis of safety at Week 24 showed that the adverse event profile of the SC and IV groups were comparable, except for SC injection site reactions. About BREVACTA BREVACTA is a randomized, double-blind, parallel-group study of Actemra SC versus placebo SC in combination with traditional DMARDs in patients with moderately to severely active RA who had an inadequate response to DMARD therapy. In the study, 656 patients were randomly assigned in a 2:1 ratio to two treatment groups receiving Actemra SC every two weeks administered with a PFS and placebo SC every two weeks with a PFS. All patients continued their background DMARD therapy. Results from BREVACTA showed RA patients who received the SC formulation of Actemra every two weeks plus DMARDs were significantly more likely to have achieved ACR20 response than those given placebo SC plus DMARDs at 24 weeks (61 percent vs. 32 percent, respectively). At Week 24, significantly less structural joint damage progression was observed in patients receiving Actemra SC plus DMARDs compared to placebo plus DMARDs as assessed radiographically and expressed as a change from baseline in the van der Heijde modified total Sharp score (mTSS) (mean change from baseline in mTSS of 0.62 vs. 1.23, respectively, with an adjusted mean difference of -0.60 [-1.1, -0.1]). No new clinically meaningful safety signals for Actemra, except SC injection site reactions, were observed in this study.
About ACR20ACR20 score represents a 20 percent reduction in tender and swollen joint counts in addition to a corresponding improvement in three of the following five parameters:
- Acute phase reactant (such as erythrocyte sedimentation rate)
- Patients Global Assessment of Disease Activity
- Physicians Global Assessment of Disease Activity
- Pain scale
- Health Assessment Questionnaire (HAQ)
- stomach tears
- changes in blood test results, including low neutrophil (white blood cells) and platelet (platelets help the blood to clot) counts, and increases in certain liver function test levels and blood cholesterol levels
- an increased risk of certain cancers by changing the way a patient’s immune system works
- hepatitis B infection
- serious allergic reactions, including death. These may happen with Actemra infusions or injections, even if they did not occur with an earlier infusion or injection.
- nervous system problems
- Upper respiratory tract infections (like common cold and sinus infections)
- Increased blood pressure (also called hypertension)
- Injection site reactions
