The Current Landscape of Diabetes Research in America
Across the country, from university medical centers to community research clinics, diabetes trials are running at a pace that would have been hard to imagine a decade ago. Some of the most active areas include GLP-1 and combination therapies for type 2 diabetes, stem cell-derived islet cell transplantation for type 1 diabetes, hybrid closed-loop insulin delivery systems, and dietary intervention studies testing whether remission is realistic for people with type 2 diabetes.
A two-year trial published in Frontiers in Endocrinology followed participants who used nutritional ketosis through a continuous remote care model and found meaningful improvements in glycemic control and medication reduction compared with usual care. Meanwhile, the CAPTAIN-T2D study, a Phase 2 trial enrolling about 1,500 participants across more than 60 locations, is examining a new compound aimed at cortisol excess in people with type 2 diabetes who have not responded well to existing treatments.
For type 1 diabetes, the VX-880 program has drawn international attention after early participants achieved periods of insulin independence following stem cell-derived islet transplantation. Real-world analyses of hybrid closed-loop systems, including data from more than 100,000 U.S. users of the Medtronic MiniMed 670G, show that time-in-range outcomes in everyday life track closely with results seen in pivotal trials.
What stands out is that not all trials are about drugs. The CREATE trial and other dietary studies have focused on whether carbohydrate restriction can lead to diabetes reversal. A low-carbohydrate Mediterranean diet caused remission in about 15% of newly diagnosed patients at one year in one study, compared with roughly 4% on a low-fat diet. That kind of data matters for the millions of Americans who prefer lifestyle approaches over adding another prescription.
What Participation Really Looks Like
Before you are accepted into any trial, you go through screening. Blood tests, a review of your medical history, sometimes imaging, and a careful look at your current medications. The screening visit itself is usually compensated, and it gives the research team a chance to confirm you meet the eligibility criteria.
Compensation varies widely. The Boston Children's Hospital type 1 diabetes diet study, for example, offers up to $1,300 for a 12-week commitment, with all meals provided at no cost. Industry-sponsored Phase 2 and Phase 3 trials often compensate in the range of $50 per visit up to several thousand dollars total, depending on the study's length and how much it demands of your schedule.
One point worth repeating: compensation is meant to offset your time, travel, and inconvenience. Institutional Review Boards keep payment levels reasonable so that financial pressure never becomes coercion. A legitimate study will never promise you a life-changing payout for enrolling.
Most trials cover study-related procedures and treatments. If the study requires an investigational drug, you do not pay for it. If the study involves CGMs, insulin pumps, or other devices, those are typically provided. You should ask specifically about travel reimbursement, lodging if the study requires overnight visits, and whether your routine diabetes care continues with your usual doctor during the trial.
A Closer Look at the Main Types of Trials
| Trial Category | Example | What It Tests | Typical Commitment | Who It Suits |
|---|
| GLP-1 and combination therapies | Next-generation incretin trials | New weight loss and glucose control drugs, some monthly dosing | 6–18 months, monthly visits | Adults with type 2 diabetes, often those with excess weight |
| Cell therapy for type 1 | VX-880, VX-264 | Stem cell-derived islet cells with or without immunosuppression | Multi-year follow-up | People with type 1 diabetes and severe hypoglycemia |
| Closed-loop insulin delivery | Hybrid closed-loop algorithm studies | Automated insulin dosing systems | 3–12 months | People with type 1 diabetes already using pumps |
| Dietary and lifestyle interventions | Nutritional ketosis, low-carb trials | Whether diet alone can improve or reverse type 2 diabetes | 3–24 months | People with type 2 diabetes preferring non-drug approaches |
| Adjunct metabolic therapies | CAPTAIN-T2D (clofutriben) | Targeting cortisol pathways in hard-to-treat type 2 diabetes | 12+ months with frequent monitoring | People with elevated cortisol risk factors |
Finding the Right Trial Near You
ClinicalTrials.gov is the official registry maintained by the National Institutes of Health, and it is the single most reliable place to search for active diabetes studies. The site is free, and you can filter by condition, recruiting status, and distance from your ZIP code. Many trials now also offer remote or virtual participation, which has expanded access considerably for people in rural areas.
When you search, keep these steps in mind. Start by entering your specific diabetes type, whether type 1 or type 2. Filter for studies marked "Recruiting." Read the eligibility criteria carefully, because trials are strict about age, diabetes duration, A1C range, and current medications. If you are on insulin, many type 2 trials will not accept you. If you are newly diagnosed with type 1 diabetes, immune therapy trials may be highly relevant.
Before contacting a research team, ask yourself a few questions. What phase is the trial? Phase 3 trials carry more safety data than Phase 1 studies. Is there a placebo arm, and if so, what are the chances you will receive the placebo? What happens to your diabetes care during the study? Can you continue your current medications? These questions should be answered transparently before you sign anything.
The Informed Consent Step
Every trial requires an Informed Consent Form, and this document is worth reading slowly. It outlines the study's purpose, the known risks, the potential benefits, and your rights as a participant. Under federal regulations, you have the right to withdraw at any time for any reason without penalty. You have the right to receive new safety information as it emerges. Your medical data is protected under HIPAA. You should never feel pressured to sign.
It helps to bring a family member or a patient advocate to the consent conversation. Ask the study coordinator to walk through each section. If a research team cannot explain the trial in plain language, that is a signal to walk away.
Practical Questions to Ask the Research Team
When you call or email a study coordinator, come prepared. Ask what treatment you will receive and the chance of receiving placebo. Ask about known side effects reported so far. Ask whether your primary care doctor or endocrinologist will be kept informed of your progress. Ask what happens to your diabetes management if you withdraw mid-study. Ask specifically about cost coverage for travel, parking, and any extra visits.
Sarah from Austin, Texas, a 54-year-old with type 2 diabetes, joined a GLP-1 combination trial after her A1C stayed above 8% despite two oral medications. The trial covered her study drug and all lab work, and she received about $900 over eight months for visits and travel. Her A1C dropped to 6.8% by the end of the study period. She still sees her regular endocrinologist, who was sent updates after each study visit.
Mike from Columbus, Ohio, a 41-year-old with type 1 diabetes for 22 years, enrolled in a hybrid closed-loop study after struggling with overnight hypoglycemia. The trial provided the pump system and training, and his time-in-range improved from 52% to 71% over six months. He now uses the same type of system commercially and says the trial gave him confidence to manage his diabetes more aggressively.
Not every story ends in success, and that is part of the honest picture. Some participants experience side effects. Some are randomized to placebo. Some find the visit schedule burdensome. A good trial coordinator will walk you through all of these possibilities before you commit.
Regional Resources Across the U.S.
Diabetes trial activity is not evenly spread. The major research hubs include Birmingham, where the University of Alabama at Birmingham runs multiple metabolic studies; Dallas, where UT Southwestern Medical Center is a regular site for type 2 diabetes trials; and Los Angeles, where the Velocity Clinical Research network operates several locations. Florida has a dense concentration of diabetes research sites, particularly in Orlando, Jacksonville, and Miami.
If you live in a state with fewer academic medical centers, look for community research networks. Velocity Clinical Research, Ark Clinical Research, and the National Clinical Research network have sites across multiple states. Many of these clinics specialize in metabolic and endocrine studies and maintain waitlists for upcoming trials.
For people on Medicare, it is worth knowing that Medicare Part B now covers therapeutic CGMs as durable medical equipment for eligible beneficiaries, including some people with type 2 diabetes who do not use insulin. Approved devices include the Dexcom G7, the Abbott FreeStyle Libre 2 and 3, and the Medtronic Guardian 4. Medicare typically covers 80% after the Part B deductible, leaving 20% coinsurance. If a trial provides a CGM at no cost, that can be a meaningful bridge while you wait for coverage decisions.
A Final Word on Making the Choice
Participating in a diabetes trial is a personal decision that sits somewhere between medical treatment and scientific contribution. For some, it is the only realistic path to a newer therapy. For others, it is a way to get closer monitoring and structured care for a year or more. And for a meaningful number of people, it is simply a way to turn a chronic condition into something they understand on a deeper level.
The research landscape in the U.S. is more active than it has ever been, and the range of options now spans drug therapies, devices, cell transplants, and dietary programs. The key is to search through official channels like ClinicalTrials.gov, ask hard questions about risks and costs, read the informed consent carefully, and make sure your regular diabetes team stays in the loop.
If you have been living with diabetes and feeling like your current plan has hit a ceiling, a clinical trial might offer a different path. Start by searching for studies recruiting in your state. Call a study coordinator. Ask the questions that matter to you. The worst that happens is you learn something about your own condition. The best that happens is you find a treatment that changes how you manage diabetes for the rest of your life.
