Opinions on drugs - Posted on Feb 25 2015

Reason for request

Inclusion

No clinical benefit demonstrated in the management of patients with type 2 diabetes

 

  • INVOKANA has Marketing Authorisation in the treatment of type 2 diabetes:

- in monotherapy when diet and exercise alone do not provide adequate glycaemic control in patients for whom use of metformin is considered inappropriate due to intolerance or a contraindication.

- in combination with other blood glucose-lowering medicinal products including insulin, when these, together with diet and exercise, do not provide adequate glycaemic control.

  • Its efficacy has been demonstrated in patients insufficiently controlled in dual therapy with metformin, in triple therapy with metformin and a sulfonylurea and in triple therapy with insulin and metformin.
  • Because of its diuretic mechanism of action, caution is recommended in patients for whom a drop in blood pressure could constitute a risk. 
  • VOKANAMET has Marketing Authorisation in the treatment of type 2 diabetes:

- in patients not adequately controlled by metformin alone at the maximum tolerated dose.

- in patients who have insufficient glycaemic control at the maximum dose of metformin combined with other blood glucose-lowering medicines including insulin.

- in patients already being treated with the combination of canagliflozin and metformin as separate tablets.

  • The fixed-dose combination of canagliflozin/metformin has not shown any clinical benefit by comparison with the free combination of canagliflozin and metformin.

Clinical Benefit

Substantial
  • substantial in patients not adequately controlled on their maximally tolerated doses of metformin alone, or in combination with a sulfonylurea;

  • substantial as replacement of the free combination of canagliflozin and metformin, at the same doses.

Moderate
  • moderate in patients on their maximally tolerated doses of metformin along with insulin, when these do not provide adequate glycaemic control.


Clinical Added Value

no clinical added value

Taking into account the lack of clinical benefit shown by the fixed-dose combination compared with the free combination of metformin and canagliflozin or other oral blood glucose lowering drugs, the Committee considers that the VOKANAMET proprietary medicinal products do not provide any improvement in actual benefit (level V, non-existent) in the treatment of patients with type 2 diabetes, whose treatment includes the free association of canagliflozin and metformin, or as part of a triple therapy in patients not adequately controlled on their maximum doses of metformin in combination with a sulfonylurea or an insulin.
