Type 2 diabetes is one of the most active areas of clinical research in the country. New medications, combination therapies, continuous glucose monitoring devices, digital health tools, and lifestyle-intervention studies enroll thousands of participants every year. Here's what to know if you're considering one.
Why so much research?
Roughly 1 in 10 U.S. adults lives with type 2 diabetes, and the toll — cardiovascular disease, kidney disease, vision loss, neuropathy — makes it one of the most consequential chronic conditions in the world. That drives research investment, which drives trial opportunities for patients.
What's being studied right now
Common categories of open trials include:
- Next-generation GLP-1 and dual-mechanism drugs aiming for better blood sugar control with less injection burden and improved weight and cardiovascular outcomes
- New oral therapies for people who don't do well on the current standard first-line options
- Combination therapy studies testing whether two existing drug classes work better together
- Continuous glucose monitor (CGM) studies looking at whether real-time glucose data changes outcomes for people not on insulin
- Digital health and coaching platforms studying whether app-based coaching improves A1C
- Prevention studies for people with prediabetes
Who typically qualifies
Eligibility varies wildly. Common criteria you'll see:
- A specific A1C range (often 7.0–10.0%)
- Diagnosed with type 2 diabetes for a minimum period (often 6+ months)
- On a specific existing medication regimen (or, sometimes, on none)
- Certain lab values within a defined range
- No history of certain complications, or specifically *with* certain complications for studies targeting those
What to expect
Diabetes trials are almost always outpatient. A typical schedule looks like:
- Screening visit — full lab panel, physical, medical history, consent
- Baseline visit to establish your starting point
- Follow-up visits every 2 to 12 weeks over 6 to 24 months
- Lab draws at most visits for A1C, fasting glucose, kidney function, and lipids
- Sometimes a CGM to wear for a portion of the trial
Compensation is usually per-visit (often $50–$150) plus travel reimbursement. Study medications, study labs, and study visits are free.
What you keep
- Your regular endocrinologist or primary care doctor stays on your care team
- Your existing insurance continues to cover care unrelated to the study
- You can withdraw at any time and return to your usual regimen
- You often get earlier-than-market access to a promising new therapy
What to weigh
- Time: Frequent visits add up. Make sure the schedule fits your life.
- Blinding: In many trials you won't know whether you're on the study drug or the comparator. The study will still be closely monitored.
- Medication changes: Some trials require pausing certain medications during a "washout" period. Make sure you understand what changes when.
- Fit with your goals: If you're happy with your current regimen and A1C, the risk-benefit calculation is different than if you've been struggling to hit your targets.
Talking to your care team
Before enrolling, tell your regular doctor. They may know the trial already, may have context on the study drug, and can help you think through whether the trial fits your overall care plan. The trial team is also expected to communicate with your regular provider throughout.
Questions to ask the trial coordinator
- What's the primary endpoint the study is measuring?
- What's the placebo or comparator, and what percentage of participants get it?
- How does this differ from what I'm on now?
- What's happened in earlier phases?
- What's the biggest known side effect?
- How is the study drug supplied — pill, injection, infusion?
- Who covers care if I develop a complication during the trial?
