Pathogenic HNF1A Variant in an Indonesian Family: Atypical Management of MODY3 Guided by Patient Comorbidity. (PubMed, AACE Endocrinol Diabetes) - "During the current admission, glycemic control was achieved, allowing gradual reduction of insulin dose and transition to oral sitagliptin/metformin XR upon discharge. dipeptidyl peptidase-4 inhibitor therapy provided effective glycemic control and offered potential neurocognitive benefits. This case underscores that while genetic confirmation of HNF1A-MODY guides therapy, treatment should be individualized based on comorbidities and prior medication history to optimize glycemic control."

Emerging Trends in List Price Adjustment Strategies Following Implementation of the Inflation Reduction Act (ISPOR 2025) - "Among products analyzed, Pfizer’s Atgam experienced the largest price increase at +15%. In contrast, significant price decreases were observed for Boehringer Ingelheim’s Atrovent (-35%) and Merck’s Januvia and Janumet/Janumet XR (-42.4%)...Excluding Januvia, the year-over-year (YoY) percent change in price for the six other IRA negotiation products with 2025 data declined from +4.0% in 2024 to +2.4% in 2025; Eliquis had the largest shift YoY from +6% in 2024 to +2% in 2025... List price adjustments reflect both product-specific and broader industry dynamics. In anticipation of IRA negotiations, IRA products are experiencing lower than average price increases. As government regulations evolve and pricing pressure on pharmaceuticals increase, assessing price adjustments in the context of anticipated payer management and government penalties will be a key consideration for manufacturers."

Pharmacokinetic comparison of sitagliptin and metformin HCl extended-release tablets versus JANUMET XR in healthy volunteers under fasting and fed conditions. (PubMed, Front Pharmacol) - "The 90% CIs of C, AUC, and AUC in both studies were all within acceptance limits (80.00%-125.00%). The results demonstrated for the first time that sitagliptin 100 mg and metformin 1000 mg produced by Nanjing Chia-Tai Tianqing Pharmaceutical Company was bioequivalent to the branded Janumet XR, and both drugs were well tolerated."

Although further studies are necessary to adapt this to common practice, providers can consider SGLT2 inhibitors as an initial treatment option in metformin intolerant patients."

[VIRTUAL] Cost-Effectiveness of Dipeptidylpeptidase-4 Inhibitors Added to Metformin in Patients with Type 2 Diabetes in China (ISPOR-EU 2020) - "OBJECTIVES : Agents that inhibit the dipeptidylpeptidase-4 (DPP-4) enzyme, including linagliptin, alogliptin, saxagliptin, sitagliptin and vildagliptin, become available for the treatment of Chinese patients with type 2 diabetes mellitus (T2DM)...Sensitivity analyses showed that the most influential parameters were the cost of DPP-4 inhibitors and their treatment efficacy. CONCLUSIONS : These results suggested that alogliptin was a preferred treatment option compared with other DPP-4 inhibitors for Chinese patients with T2DM inadequately controlled on metformin monotherapy."

Efficacy and safety with exenatide once weekly: clinical trial results from 10 randomised trials (the DURATION programme) (EASD 2018) - "...The DURATION-1 study was extended to 7 years of follow-up; currently, this is the longest duration that any GLP-1RA has been studied in a clinical trial.Materials and Patients received ExQWS-AI or ExQW as monotherapy or in combination with other antidiabetic drugs (e.g. metformin, sulphonylurea, a thiazolidinedione [pioglitazone], dapagliflozin [DAPA] and insulin glargine). Efficacy and safety data were summarised from individual studies. In total, 2251 patients received ExQW 2 mg (n=1841) or ExQWS-AI 2 mg (n=410); 2870 patients received comparators (non-GLP-1RAs, n=1481 [metformin, sitagliptin, pioglitazone, insulin glargine, and DAPA], ExBID [n=416], liraglutide [n=450], ExQW+DAPA [n=231], or placebo [n=292])...
