The goal of the Diabetes Patient Progress Documentation (DPV) Initiative is to improve outcomes for people with diabetes in routine care through standardized documentation, objective comparison of quality indications, and multicenter treatment research. Data from the anonymized DPV registry are used for therapy research on practice-relevant questions. The network is anchored at the University of Ulm.

The Dopamine genetics study will investigate the influence of the drug Bromocriptine on weight loss in relation to the fat mass and obesity (FTO) genotype. Furthermore, effects on body fat content, insulin action in the brain, and other metabolic processes will be investigated. Bromocriptine will be compared to a placebo (preparation without active ingredient).

General requirements for study participation: (recruitment ended)

• Women and men between 18 - 70 years of age
• BMI ≥30 kg/m²

ATTAIN-2 is a drug trial evaluating the safety and efficacy of a once-daily oral regimen of orforglipron compared to a placebo (preparation without active ingredient) in addition to a healthy diet and physical activity on body weight in overweight or obese people with type 2 diabetes. The study will last approximately 77 weeks and is initiated by Eli Lilly. 

General requirements for study participation: (recruitment ended)

• Women and men between the ages of ≥18 years
• BMI ≥27 kg/m²
• At least one unsuccessful diet attempt in the past
• Diagnosis of type 2 diabetes with an HbA1c value of ≥7% to ≤10% and stable therapy for at least 90 days before study entry

The study is sponsored by Novo Nordisk, and participants will participate for a total of 5 years. They will be randomly assigned to receive Semaglutide or a placebo (preparation without active ingredient).

Both study drugs act in the liver. The study is also investigating a combination of Semaglutide and another weight-loss drug (NNC0174-0833), which may provide another treatment option for NASH. The study duration for participants is approximately 19 months.

In 2002, the German Acromegaly Registry was established by the German Society of Endocrinology with the aim of improving the medical care of patients with acromegaly. For this rare disease, only a few data on epidemiology, diagnostics, therapy, and long-term prognosis are available. This information gap will be closed with the help of the registry.

The Acromegaly Registry systematically collects clinical data of patients with acromegaly diagnosed and treated in Germany. To date, the data of more than 3,500 patients have been recorded in a structured manner. The Institute of Endocrinology and Diabetes in Lübeck is one of currently 57 active centers. The data are entered pseudonymously web-based into the database of the German Acromegaly Registry.
