What is this study?
Blood sugar levels are controlled by insulin, a hormone made by cells in the pancreas. After a meal, carbohydrates are broken down into glucose which is absorbed from the intestine into the blood leading to a rise in glucose (blood sugar) which triggers the secretion of insulin.
It is , overseen by an independent and licensed medical staff.
Read the full clinical description
Blood sugar levels are controlled by insulin, a hormone made by cells in the pancreas. After a meal, carbohydrates are broken down into glucose which is absorbed from the intestine into the blood leading to a rise in glucose (blood sugar) which triggers the secretion of insulin. Insulin binds to cells in several tissues including liver, muscle, and fat, triggering cells to take up glucose and bring the blood glucose level back to normal. A high blood sugar level is known as diabetes. The most common form of diabetes, type 2 diabetes, is caused by insulin resistance; that is, a reduced ability of insulin to stimulate glucose uptake into cells. The body compensates for insulin resistance by making more insulin; type 2 diabetes occurs when the pancreas can no longer make enough insulin to control blood glucose. The high blood glucose and insulin levels lead to long-term complications such as heart attacks, kidney failure, reduced sensation and poor circulation in the feet and legs. High insulin levels also increase the incidence of cancers, stroke, and dementia. Reducing blood glucose levels with oral medications and insulin reduces risk of diabetic complications. There are several types of oral medications available for treating diabetes; however, they do not always control blood glucose adequately. In addition, these drugs have complications and are not used to treat insulin resistance and prediabetes - a condition when blood glucose is higher than normal but not high enough to be classified as diabetes. Prediabetes often progresses to diabetes over a period of months or years. Effective and safe treatments for insulin resistance may prevent the onset of diabetes or even reverse diabetes if diagnosed in its early stages before substantial damage to the pancreas has occurred. HP-211 is a botanical extract whose active ingredients are derived from herbs and vegetables present in normal diets. HP-211 has been shown in laboratory studies in cell culture, in animal studies, and in a previous Phase 1 study to enhance the ability of insulin to stimulate glucose uptake into cells. Thus, HP-211 may reduce the blood glucose and circulating insulin levels of subjects with type 2 diabetes after a meal. HP-211 may also reduce glucose and insulin responses to a greater extent in insulin-resistant as compared to insulin-sensitive subjects. Subjects will take 0, 1, 2 or 3 tablets of HP-211 in the morning and evening for 90 days. Hemoglobin A1c (HbA1c, or "A1c"), a measure of the average amount of glucose present in the blood, will be measured during the trial period.
Who this study is looking for
In plain language, from the study's own rules. The study team confirms the full details with you — this isn't a final yes or no.
✅ You may be able to join if…
- •Adults with type 2 diabetes for more than 3 months and no longer than 5 years (per ADA diagnostic criteria).
- •A1c must be greater than 6.5% and at most 10% based on the central lab at screening (Visit 1).
- •Either (1) stable, maximum dose metformin for at least 3 months before the study, with no dose or treatment changes in the last 3 months, or (2) stable diet and exercise only for at least 3 months.
🚫 You may not be able to join if…
- •People with known type 1 diabetes.
- •People with diabetic complications.
- •People currently taking (or who took within the last 4 weeks) other diabetes medicines besides metformin, including insulin or GLP-1 receptor agonists (GLP-1 RAs) — prior treatment must have been stopped at least 3 months before screening.
- •People with high blood pressure at screening (systolic >150 mmHg or diastolic >100 mmHg), on average after three supine measurements, or with a known history of renal artery stenosis.
- •People with an ECG heart rhythm/structure problem at screening, including QTcF above the sex-specific limits (males >450 msec, females >470 msec), left bundle branch block, or a cardiac arrhythmia that required medical or surgical treatment within 6 months before Visit 1.
Are you a good fit?
Simplified highlights. The study team always confirms the full details with you.
- ✓Adults roughly 18–any age
- ✓Have Type 2 diabetes
- !May require a break from current GLP-1 medications
What to expect, step by step
- 1
Usually a few weeks
The study team checks whether the study is a good fit for you, with a visit and sometimes lab tests. You can ask any questions before deciding.
- 2
Treatment
If you join and choose to continue, you receive the study treatment and are watched closely by medical staff.
- 3
Follow-up
After treatment, the team checks on your health and confirms the visit schedule with you. You can leave the study at any point.
Has this treatment been tested before?
Yes. This treatment has already been through earlier human studies for safety before reaching this stage.
What you need to know before you apply
What is this study testing?+
Blood sugar levels are controlled by insulin, a hormone made by cells in the pancreas. After a meal, carbohydrates are broken down into glucose which is absorbed from the intestine into the blood leading to a rise in glucose (blood sugar) which triggers the secretion of insulin.
Is it safe? Who makes sure of that?+
This is a mid-stage study (Phase 2), looking at safety and whether the treatment works. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
I take a GLP-1 medication (like Ozempic or Wegovy). Can I still join?+
Maybe. This study may ask you to pause certain weight or diabetes medications for a period of time (a 'washout') before joining, or it may be looking for people not currently on them. The coordinator will review your medications with you — don't stop any medication on your own.
Does it cost anything? Will I be paid?+
The study treatment and study-related visits are provided at no cost to you. This study may also compensate you for your time and travel — the team will tell you the amount before you join. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
