What the trial was testing
The ACHIEVE-1 enrolled 559 patients with type 2 diabetes. The study was sponsored by Eli Lilly and Company and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was a large trial designed to confirm whether the treatment works well enough for wider use. Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
People taking orforglipron lowered their A1C by up to 1.5 percentage points after 40 weeks.
The New England journal of medicine · 2025 · NCT05971940
These findings — that orforglipron lowered A1C by about 1 to 1.5 points more than placebo — were published in the The New England journal of medicine and represent the headline result of the study.
Researchers tracked outcomes across 559 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with type 2 diabetes, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
This was a large-scale study and the results were positive. Orforglipron is not yet FDA-approved but is in late-stage testing. If you have type 2 diabetes and are interested in new treatment options, talk with your doctor about this medication or similar GLP-1 treatments that are already available.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.
Open type 2 diabetes trials
Integrated Hyperglycaemia Incentivised Postnatal Surveillance Study (I-HIPS)
This study aims to test the following hypotheses in a randomized controlled trial of post-partum women with a history of gestational diabetes mellitus (GDM) that will be followed up for up to 4 years: 1. Post-partum pregnancy is ideal for behavioural modification and adopting a healthy lifestyle. Using the continous glucose monitoring (CGM) sensor and an exercise tracker will promote self-motivation and awareness by positive reinforcement and behavioural changes to improve diet, control body weight and increase physical activity in this group of post-partum women who are at high risk for developing Type II Diabetes. 2. The use of the continous glycose monitoring (CGM) sensor and exercise tracker will motivate women to modify their dietary food intake and physical activity over time, reducing their cardiovascular risk factors for developing metabolic syndrome by lowering their baseline blood pressure, BMI, reducing their waist circumference and body fat mass, glycaemic levels and fasting lipids within the targeted healthy range. 3. There will be an increase in the quality adjusted life years (QALYs) gained based on improvements in HbA1C and other proximal outcomes at the end of the trial.
NT-ProBNP-based Heart Failure Screening and Prevention Trial in Patients With Type 2 Diabetes: STRONG-DM Study
A pragmatic, randomized clinical trial to evaluate the effect of a heart failure (HF) risk assessment and prevention strategy incorporating HF clinical risk scores (WATCH-DM) with cardiac biomarker (NT-proBNP) paired with a clinical decision support tool to implement an intensive prevention strategy among patients with high risk focused on implementation of evidence-based HF preventive therapies.
