- What you take
- NA-931, given as part of the study. Check ClinicalTrials.gov for this trial's study groups, including any placebo or comparison medicine.
- How long it lasts
- The study runs about 16 months.
- What you get
- Many clinical trials pay for the study medication and the study visits. Some also pay for travel. Ask the study team what this one covers before you sign the consent form.
What this study is for
Primary condition: Obesity and Overweight.
Full scientific study title: Safety and Efficacy of NA-931 and Tirzepatide in Adults Who Are Overweight or Obese.
Who can join
Adults 19 to 80, have obesity or are overweight, BMI 27+. A site coordinator confirms whether you qualify during a free screening visit. The exact medical requirements are below.
Full medical eligibility (for you and your doctor)verbatim from the registry
This is the exact wording from ClinicalTrials.gov, including clinical measures (lab values, imaging scores). Bring it to your doctor if any of it is unclear.
Key inclusion criteria
- A written informed consent must be obtained before any study-related assessments are performed.
- Men and women between 18 and 80 years, inclusive; women of child-bearing potential (defined as those who are not post-menopausal or post-surgical sterilization) must meet both of the following criteria:
- Two negative pregnancy tests (at screening and at randomization, prior to dosing)
- Use of intrauterine device, from at least 3 months before the baseline visit through at least 4 months after the last dose of NA-931/placebo oral, and an additional contraceptive (barrier) method from screening through at least 4 months after the last dose of NA-931/placebo oral.
- Body mass index (BMI) ≥ 30 or BMI ≥ 27 with one or more obesity-associated comorbidities (e.g., hypertension, insulin resistance, sleep apnea, or dyslipidemia)
Key exclusion criteria
- • History of, or known hypersensitivity to, monoclonal antibody drugs or a contraindication to Tirzepatide (Zepbound® or Mounjaro®)
- Use of other investigational drugs at the time of enrollment or within 30 days or 5 half-lives of enrollment, whichever is longer, or longer if required by local regulations
- Treatment with any medication for the indication of obesity within the past 30 days before screening
- Diagnosis of diabetes requiring current use of any antidiabetic drug or HbA1c ≥ 6.5% Note: Metabolic syndrome is not an exclusion, even if managed with an anti-diabetic drug such as metformin or an SGLT2 inhibitor. A diagnosis of prediabetes or impaired glucose tolerance managed exclusively with non-pharmacologic approaches (e.g., diet and exercise) is not an exclusion.
- Any chronic infections likely to interfere with study conduct or interpretation such as hepatitis B (HBV), hepatitis C (HCV), or human immunodeficiency virus (HIV). History of hepatitis A or hepatitis C successfully treated is not exclusionary. Active COVID-19 infection.
