Dipeptidyl peptidase-4 inhibitor

Inhibitors of dipeptidyl peptidase 4 (DPP-4 inhibitors or gliptins) are a class of oral hypoglycemics that block the enzyme dipeptidyl peptidase-4 (DPP-4). They can be used to treat diabetes mellitus type 2.

DPP-4 inhibitors and GLP-1

The first agent of the class – sitagliptin – was approved by the FDA in 2006.[1]

Glucagon increases blood glucose levels, and DPP-4 inhibitors reduce glucagon and blood glucose levels. The mechanism of DPP-4 inhibitors is to increase incretin levels (GLP-1 and GIP),[2][3][4] which inhibit glucagon release, which in turn increases insulin secretion, decreases gastric emptying, and decreases blood glucose levels.

A 2018 meta-analysis found no favorable effect of DPP-4 inhibitors on all-cause mortality, cardiovascular mortality, myocardial infarction or stroke in patients with type 2 diabetes.[5]

Examples

Drugs belonging to this class are:

  • Sitagliptin[6] (FDA approved 2006, marketed by Merck & Co. as Januvia)
  • Vildagliptin[7] (EU approved 2007, marketed in the EU by Novartis as Galvus)
  • Saxagliptin (FDA approved in 2009, marketed as Onglyza)
  • Linagliptin (FDA approved in 2011, marketed as Tradjenta by Eli Lilly and Company and Boehringer Ingelheim)[8]
  • Gemigliptin (approved in Korea in 2012, marketed by LG Life Sciences)[9] Marketed as Zemiglo
  • Anagliptin (approved in Japan in 2012, marketed by Sanwa Kagaku Kenkyusho Co., Ltd. and Kowa Company, Ltd.)[10]
  • Teneligliptin (approved in Japan in 2012[11])
  • Alogliptin (FDA approved 2013, marketed by Takeda Pharmaceutical Company)
  • Trelagliptin (approved for use in Japan in 2015)
  • Omarigliptin (MK-3102) (approved in Japan in 2015,[12] developed by Merck & Co.; research showed that omarigliptin can be used as once-weekly treatment and generally well-tolerated throughout the base and extension studies[13])
  • Evogliptin (approved for use in South Korea[14])
  • Gosogliptin (approved for use in Russia[15])
  • Dutogliptin (being developed by Phenomix Corporation), Phase III[16]

Other chemicals which may inhibit DPP-4 include:

  • Berberine, an alkaloid found in plants of the genus Berberis, inhibits dipeptidyl peptidase-4 which may at least partly explains its antihyperglycemic activity.[17]

Adverse effects

In those taking sulphonylureas, there is an increased risk of low blood sugar.[18]

Adverse effects, including nasopharyngitis, headache, nausea, heart failure, hypersensitivity and skin reactions.

The U.S. Food and Drug Administration (FDA) is warning that the type 2 diabetes medicines like sitagliptin, saxagliptin, linagliptin, and alogliptin may cause joint pain that can be severe and disabling. FDA has added a new Warning and Precaution about this risk to the labels of all medicines in this drug class, called dipeptidyl peptidase-4 (DPP-4) inhibitors.[19] However, studies assessing risk of rheumatoid arthritis among DPP-4 inhibitor users have been inconclusive.[20]

A 2014 review found increased risk of heart failure with saxagliptin and alogliptin, prompting the FDA in 2016 to add warnings to the relevant drug labels.[21]

A 2018 meta analysis showed that use of DPP-4 inhibitors was associated with a 58% increased risk of developing acute pancreatitis compared with placebo or no treatment.[22]

A 2018 observational study suggested an elevated risk of developing inflammatory bowel disease (specifically, ulcerative colitis), reaching a peak after three to four years of use and decreasing after more than four years of use.[23]

Cancer

In response to a report of precancerous changes in the pancreases of rats and organ donors treated with the DPP-4 inhibitor sitagliptin,[24][25] the United States FDA and the European Medicines Agency each undertook independent reviews of all clinical and preclinical data related to the possible association of DPP-4 inhibitors with pancreatic cancer. In a joint letter to the New England Journal of Medicine, the agencies stated that they had not yet reached a final conclusion regarding a possible causative relationship.[26]

A 2014 meta-analysis found no evidence for increased pancreatic cancer risk in people treated with DPP-4 inhibitors, but owing to the modest amount of data available, was not able to completely exclude possible risk.[27]

Combination drugs

Some DPP-4 inhibitor drugs have received approval from the FDA to be used with metformin concomitantly with additive effect to increase the level of glucagon-like peptide 1 (GLP-1) which also decreases hepatic glucose production.
