A Bridging Study of Efsubaglutide Alfa in Healthy Adults in Brazil
Brazil48 participantsStarted 2026-06-01
Plain-language summary
This is a Phase I, randomized, double-blind, placebo-controlled, single-dose study in healthy adult participants in Brazil to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of YN-011. Participants will be randomized to receive a single subcutaneous dose of YN-011 1 mg, YN-011 3 mg, or matching placebo. The study includes screening, approximately 2 days of study-site confinement from the day before dosing to 24 hours after dosing, and outpatient follow-up for 4 weeks. Assessments include safety monitoring, PK blood sampling, PD evaluations, and immunogenicity testing.

Inclusion criteria
. Healthy male or female adults, aged 18-45 years (both inclusive) at the time of signing the informed consent form (ICF).
. Body mass index (BMI) between 18-28 kg/m2 (both inclusive). Male participants must weigh no less than 50 kg, and female participants must weigh no less than 45 kg.
. Voluntary participation in this study, as documented by the written signature of two copies of the ICF.
. Negative serum pregnancy test for women of childbearing potential (WOCBP) during screening period. WOCBP and fertile male participants with WOCBP partners must use highly effective contraception methods without planning to become pregnant or to donate sperm or eggs throughout this study (from signing the ICF to at least 3 months after completion of this study).
. Be able to maintain good communication with the investigators and comply with all requirements of protocol to complete all trial procedures.
Exclusion criteria
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

. Known or suspected allergy to the investigational medicinal product, its components or drugs of the same class, or a clinically significant drug allergy, or a history of atopic allergic disease.
. Previously or currently diagnosed diabetes mellitus (T1D or T2D) or prediabetes, according to the diagnostic criteria of the Brazilian Diabetes Society (SBD) guideline, defined by any of the following laboratory findings:
. History of clinically significant endocrine disorders that may affect glucose metabolism, body weight, or drug PK, including but not limited to Cushing's syndrome; acromegaly; pheochromocytoma; untreated or uncontrolled thyroid disorders (hyperthyroidism or hypothyroidism); polycystic ovary syndrome (PCOS) with metabolic abnormalities; adrenal insufficiency or other adrenal disorders; pituitary disorders affecting hormonal regulation.
. History of acute or chronic pancreatitis, symptomatic gallbladder disease (those who have recovered from cholecystectomy and have no sequelae after treatment are allowable to be enrolled), pancreatic injury or other high-risk factors that may lead to pancreatitis, or screening serum amylase or lipase \>2X upper limit of normal (ULN).
. History of significant gastrointestinal (GI) disorders (e.g., gastroparesis, active ulcers within 6 months, or long-term use of medications that directly affect GI motility, or GI surgery within 6 months prior to screening.
. History or presence of hepatic, renal, cardiovascular, neurological, psychiatric, psychological or immunological disorders.
. Clinically significant abnormalities in physical examination, vital signs, laboratory tests, or 12-lead ECG at screening, and investigators consider that these abnormalities may affect participant's safety or study results. ECG abnormalities including but not limited to: second- or third-degree atrioventricular block; long QT syndrome or QTcF \> 450 ms (males) or \> 470 ms (females). (If the QTcF \> 450 ms (males) or \> 470 ms (females), two additional ECG measurements should be repeated, and the mean of the three values should be used to determine the participant's eligibility.); left bundle branch block;Wolff-Parkinson-White syndrome; Or other clinically significant 12-lead ECG abnormalities requiring treatment.
. Use of any prescription or over-the-counter (OTC) medications, traditional Chinese medicine within 12 months prior to screening that may confound PK, PD, or safety assessments.
