Main results

TECOS study

Meta-analysis of the data from the TECOS, SAVOR-TIMI 53, and the EXAMINE studies


In the TECOS study, pancreatitis and pancreatic cancer were uncommon events with rates that were not statistically significantly different between the sitagliptin and placebo groups, although numerically more sitagliptin-treated participants developed pancreatitis and fewer developed pancreatic cancer. The meta-analysis of the TECOS, SAVOR-TIMI 53, and the EXAMINE studies suggests a small increased risk for pancreatitis with DPP-4i therapy.

Editorial comment

In their editorial article [9], DeVries and Rosenstock discuss the topic of pancreatitis as a difficult to assess safety issue, because of controversial and conflicting reports. Reliable evaluations of the association between the disease and the use of DPP-4is are lacking, due to methodological limitations. They state that: ‘It is probably better to acknowledge that we cannot be sure about the relative contribution of different risk factors in an individual developing pancreatitis, and conceivably an incretin-based drug could be an important contributing factor affecting precisely those at risk for developing pancreatitis.’ On the other hand, they point out that there are no data to justify the avoidance of DPP-4is in patients with risk factors for pancreatitis, given the effectiveness and safety profile of these agents.

They conclude as follows: ‘Thus, we can conclude that pancreatitis is an established but rare side effect of DPP-4 inhibitors that occurs at a very low frequency. We should inform patients on this potential side effect, and in people on DPP-4 inhibitors having even mild gastrointestinal symptoms suggestive of pancreatitis, it would be justified to measure pancreatic enzymes and appropriate to perform an abdominal ultrasound to exclude gallstones. On the basis of the evidence so far, perhaps in some patients when gallstones are present (even if asymptomatic) and/or when lipase levels are >3 times normal (even if fluctuating), there may be enough basis to consider replacing an incretin-based agent used and consider an alternative therapy.’
