RoACTEMRA recommended for approval in Europe for the reduction of joint damage and improvement in physical function in rheumatoid arthritis

Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today that RoACTEMRA has received a recommendation for approval from the European Medicines Agency (EMA) Committee for Medicinal Products for Human Use (CHMP) to extend its indication to reduce the rate of progression of joint damage and improve physical function in patients with rheumatoid arthritis (RA), when given in combination with methotrexate. Joint damage in RA often begins early in the disease and can lead to permanent disability, so inhibiting this structural damage to patients’ joints is a critical measure of the effectiveness of an RA treatment.

“We are delighted by the positive opinion granted by the CHMP,” said Hal Barron, M.D., executive vice president, Global Development and chief medical officer. “The significant effect of RoACTEMRA on joint damage will allow many patients to continue to enjoy their lives without the worsening disability usually associated with the disease. Combined with RoACTEMRA’s consistently high signs and symptoms remission rates across patient types and well characterised safety profile, this further demonstrates the benefits of RoACTEMRA as a comprehensive RA treatment.”

The announcement from the CHMP follows positive two-year data from the phase III LITHE1 trial which showed that patients receiving RoACTEMRA in combination with methotrexate (MTX) had significantly less damage to their joints at two years, compared to patients who received MTX in the control group.  The outcome was determined by x-rays which measured over time the progression of bone erosions and narrowing of joint spaces. The data showed that with long-term use, patients with RA treated with RoACTEMRA 8mg/kg plus MTX suffered 81% less damage to their joints compared to those treated in the control group at week 104.

RoACTEMRA is currently licensed in Europe for use in combination with MTX, to treat adult patients with moderate to severe RA who responded inadequately to, or who were intolerant to, previous therapy with one or more disease-modifying anti-rheumatic drugs (DMARDs) or tumour necrosis factor antagonists (anti-TNFs).2 In these patients, RoACTEMRA can be given as monotherapy in cases of intolerance to MTX, or where continued treatment with MTX is inappropriate.2 Of the RA patients treated with current biologic therapy, up to 40% do not have a satisfactory outcome and at present have few treatment alternatives.3 Therefore there is a significant unmet need for effective treatment options for patients whose quality of life continues to be impacted by this serious disease.

ACTEMRA was filed in the US in March 2010 for the prevention of structural joint damage and to improve physical function in adults with moderately to severely active RA. This filing followed ACTEMRA’s approval by the FDA in January 2010 as the first humanized interleukin-6 (IL-6) receptor-inhibiting monoclonal antibody to treat adult patients with moderately to severely active RA who have had an inadequate response to one or more tumor necrosis factor (TNF) antagonist therapies.

About the LITHE (TociLIzumab Safety and THE Prevention of Structural Joint Damage) study

The LITHE study, a randomised, double-blind, placebo-controlled trial was designed to evaluate the efficacy of TCZ plus MTX in preventing structural joint damage and improving physical function over two years. LITHE was an international study, including 15 countries and 1196 patients with moderate to severe RA who had an inadequate response to MTX. In this randomised study, patients received either RoACTEMRA (4 mg/kg or 8 mg/kg, one infusion every four weeks) in combination with MTX or MTX alone. Results from the 24-month analysis showed that at 104 weeks, total Genant-modified Sharp Score change from baseline for the RoACTEMRA 8mg + MTX, 4mg +MTX, and MTX alone groups were: 0.37, 0.58 and 1.96 respectively.  The HAQ-DI AUC change from baseline, adjusted mean scores were:  -320.8, -287.5 and -139.4 respectively at 24 months.1

About RoACTEMRA/ACTEMRA

RoACTEMRA/ACTEMRA is the result of research collaboration by Chugai and is also being co-developed globally with Chugai. RoACTEMRA/ACTEMRA is the first humanised interleukin-6 (IL-6) receptor-inhibiting monoclonal antibody. An extensive clinical development programme of five Phase III trials was designed to evaluate clinical findings of RoACTEMRA/ACTEMRA, all of which met their primary endpoints. RoACTEMRA/ACTEMRA was first approved in Japan, and launched by Chugai in June 2005 as a therapy for Castleman's disease; in April 2008, additional indications for rheumatoid arthritis (RA), juvenile idiopathic arthritis and systemic-onset juvenile idiopathic arthritis were also approved in Japan. RoACTEMRA/ACTEMRA was approved in the European Union in January 2009 for the treatment of RA in patients who have either responded inadequately to, or who were intolerant to, previous therapy with one or more disease modifying anti-rheumatic drugs (DMARDs) or tumour necrosis factor (TNF) inhibitors. It is also approved for use in several other countries, including India, Brazil, Switzerland, and Australia. RoACTEMRA/ACTEMRA was most recently (January 2010) approved in the United States for the treatment of adult patients with moderately to severely active RA who have had an inadequate response to one or more TNF inhibitors.

The overall safety profile of RoACTEMRA/ACTEMRA is consistent across all global clinical studies. The serious adverse events reported in RoACTEMRA/ACTEMRA/ACTEMRA clinical studies include serious infections, gastrointestinal perforations and hypersensitivity reactions including anaphylaxis.  The most common adverse events reported in clinical studies were upper respiratory tract infection, nasopharyngitis, headache, hypertension and increased ALT.  Increases in liver enzymes (ALT and AST) were seen in some patients; these increases were generally mild and reversible, with no evidence of hepatic injuries or any observed impact on liver function.  Laboratory changes, including increases in lipids (total cholesterol, LDL, HDL, triglycerides) and decreases in neutrophils and platelets, were seen in some patients without association with clinical outcomes. Treatments that suppress the immune system, such as ACTEMRA, may cause an increase in the risk of malignancies.
