Safety and Efficacy of NA-931 and Tirzepatide in Adults Who Are Overweight or Obese

Официальное название

A Randomized, Double-Blind, Placebo-Controlled Multi-Center Study of Oral NA-931, Alone or in Addition to Open Label Subcutaneous Tirzepatide , to Investigate the Efficacy and Safety in Overweight or Obese Men and Women

Обзор

A phase 2 study to assess the efficacy of NA-931 alone or in addition to Tirzepatide to assess efficacy and safety in overweight or obese men and women

Подробное описание

This Phase 2 study investigates if NA-931 in addition to Tirzepatide can demonstrate synergic effects by enhancing efficacy and reducing adverse events including preserve/increase muscle mass in the presence of weight and/or fat mass loss.

Критерии участия

Критерии включения

• 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)
• Stable body weight (± 5 kg) within 90 days of screening, and body weight <150 kg
• Have a history of at least one self-reported unsuccessful behavioral effort to lose body weight
• Able to communicate well with the Investigator, comply with the study requirements and adhere to the diet and activity programs for the study duration

Критерии исключения

• • 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.
• Donation or loss of 400 mL or more of blood within 8 weeks prior to initial dosing, or longer if required by local regulation, or plasma donation (> 250 mL) within 14 days prior to the first dose
• Any disorder, unwillingness, or inability not covered by any of the other exclusion criteria, which in the Investigator's opinion, might jeopardize the participant's safety or compliance with the protocol
