Trelagliptin (trade name Zafatek) is a pharmaceutical drug used for the treatment of type 2 diabetes (diabetes mellitus).[1]


It is a highly selective dipeptidyl peptidase-4 inhibitor that is typically used as an add on treatment when the first line treatment of metformin is not achieving the expected glycemic goals; though it has been approved for use as a first line treatment when metformin cannot be used.[1]


DPP-4 inhibitors activate T-cells and are more commonly known as T-cell activation antigens (specifically CD26).[1][2] Chemically, it is a fluorinated derivative of alogliptin.


Formulated as the salt trelagliptin succinate, it was approved for use in Japan in March 2015.[3] Takeda, the company that developed trelagliptin, chose to not get approval for the drug in the US and EU.[1] The licensing rights that Takeda purchased from Furiex Pharmaceuticals for DPP-4 inhibitors included a clause specific to development of this drug in the US and EU.[1] The clause required that all services done for phase II and phase III clinical studies in the US and EU be purchased through Furiex.[1] Takeda chose to cease development of this drug in the US and EU because of the high costs quoted by Furiex for these services.[1] Gliptins have been on the market since 2006 and there are 8 gliptins currently registered as drugs (worldwide).[4] Gliptins are an emerging market and are thus being developed at an increasing rate; there are currently two gliptins in advanced stages of development that are expected to be on the market in the coming year.[4]

Gliptins are thought to have cardiovascular protective abilities though the extent of these effects is still being studied.[4] They are also being studied for the ability that this class of drugs has at promoting B-cell survival.[4]

Administration and dosing[edit]

Chemical structure of trelagliptin succinate

Similar drugs in the same class as trelagliptin are administered once daily while trelagliptin is administered once weekly.[1][5] Alogliptin (Nesina) is the other major DPP-4 inhibitor on the market. It is also owned by Takeda and is administered once daily. A dosing of once per week is advantageous as a reduction in the frequency of required dosing is known to increase patient compliance.[1][2]

Brand names[edit]

In Bangladesh it is marketed under the trade name Wedica.
