The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the European Commission (EC) has granted approval to update the INVOKANA® (canagliflozin) and VOKANAMET® (canagliflozin and metformin) labeling to include changes to the indication statement for the treatment of adults with insufficiently controlled type 2 diabetes mellitus (T2DM) as an adjunct to diet and exercise. The decision means that the product information now includes data on the reduction in major adverse cardiovascular (CV) events (cardiovascular mortality, non-fatal myocardial infarction, or non-fatal stroke) in patients with type 2 diabetes mellitus (T2DM) who had either a history of CV disease or at least two CV risk factors, in addition to the existing study results on improving glycemic control.
"We hope this approval will not only provide clinicians with a more detailed overview of canagliflozin but also help them when making informed treatment decisions which are most appropriate for their patients. Type 2 diabetes mellitus is one of the most common forms of diabetes and accounts for the majority of diabetes cases worldwide so it is extremely important that we continue improving outcomes for these patients," said Dr. Jose Antonio Buron, Vice-President Medical Affairs EMEA, Janssen-Cilag Farmacêutica, Lda.
The EC's decision follows a recommendation from the Committee for Medical Products for Human Use (CHMP) that was based on data from the CANVAS Program, the largest completed CV outcomes trial to date for an SGLT2 inhibitor. The study, which included over 10,000 patients started in 2009, met its primary endpoint and showed canagliflozin significantly reduced the combined risk of CV death, myocardial infarction and non-fatal stroke, versus placebo in adult patients with T2DM who had either a history of CV disease or at least two CV risk factors.
Canagliflozin also significantly lowered the risk of hospitalization for heart failure and demonstrated improved renal outcomes. Adverse events reported in the CANVAS Program were generally consistent with the known safety profile of canagliflozin. However, the study found that, in patients with T2DM who had established CV disease or at least two risk factors for CV disease, canagliflozin was associated with an approximately 2-fold increased risk of lower limb amputation with the rate of amputation over standard of care being 0.63/100 patient years for canagliflozin versus 0.34/100 patient years for placebo which corresponds to an additional risk of 0.29/100 patient years. The risk of amputations across the class has previously been investigated by the EMA, and this is reflected in a warning in the labeling of SGLT2 inhibitors.
Canagliflozin was approved in the European Union by the European Commission in November 2013 and is indicated for the treatment of adults with insufficiently controlled type 2 diabetes mellitus. Approval was based on a comprehensive global Phase 3 clinical trial program.
