A Phase 2 Study Evaluating the Co-Administration of Bremelanotide With Tirzepatide for the Treatment of Obesity

Korábbi kezelés

• Subjects with active alcohol dependence and/or drug use (with Cannabis exception) as assessed by the Investigator will be excluded from the study.
• Has been on bremelanotide therapy (Vyleesi) within the past 6 months prior to screening date.
• Within the past three month, has used cyclosporine A, adrenocorticotropic hormones, long-term corticosteroids (> 20 mg qd or its equivalent for > 3 months), or cytotoxic agents.
• Has had clinically significant body weight change (≥5%) or dieting attempts in the prior 90 days (per subject reported information) and Treatment Period 1.
• Use of Anti-Obesity Medication (AOM) within a 90-day period prior to screening (Note: subjects who have taken or are still taking tirzepatide may participate in study if exclusion criteria #8 has not been met. AOM medications will also include medications that are being used off-label for weight loss).
• Prior obesity or weight loss surgery or presence of gastrointestinal implant or bariatric surgery or other weight loss procedures within 2 years of screening (i.e. liposuction, abdominoplasty, intragastric balloon, cholecystectomy, etc.)
• Has taken any experimental drug or therapy within 28 days / 5 half-lives of trial treatment or concurrently participating in another clinical trial.
• Planned bariatric surgery or planned major surgeries during the study time period.
• Prior hypersensitivity to tirzepatide component.
• Is taking concomitant oral drugs that are dependent on threshold concentrations for efficacy (e.g., antibiotics) since bremelanotide slows gastric emptying and thus has the potential to reduce the rate and extent of absorption of concomitantly administered oral medications

Más betegség

• Have a known allergy or intolerance to Melanocortin peptides.
• Have significant medical illnesses that cannot be adequately controlled with appropriate therapy and may obscure toxicity, dangerously alter drug metabolism, or compromise the subject's ability to participate in the trial, as determined by the Investigator, such as endocrinologic disorders accounting for obesity such as Cushing Disease, syndrome or monogenic obesity and exclusions of organ transplant recipients, those on wait lists, or those on anti-rejection medication as the potential effect on gastric emptying effecting pharmacokinetics.
• Has type 1 diabetes.
• Has a history of clinically significant bradycardia and/or a heart rate less than 50 bpm at screening.
• Has multiple endocrine neoplasia syndrome type 2.
• Has personal or family history of MEN 2 syndromes or Medullary Thyroid Cancer.
• Has hypertension (by medical history or by screening vital signs) and/or known cardiovascular disease.
  • Note: If subject presents at screening with elevated blood pressure and no supporting evidence of hypertension; subject may wait approximately 1 hour to have blood pressure rechecked; if readings are still elevated, subject may return to the site approximately 24 hours later to have blood pressure rechecked.
• Has a diagnosis of type 2 diabetes

Laborértékek

• Subjects with a positive Serum Antigen/Antibody Hepatitis Panel (Hep B and C) and HIV antibody test Human Immunodeficiency Virus (HIV) antibody.
  • Note: subject with positive hepatitis C antibody but negative PCR test for active Hepatitis C viral shedding will be allowed to participate in the study. Subjects with a positive Hepatitis B surface antigen antibody or core antigen antibody will be allowed to participate in the study. Subjects with circulating hepatitis B surface antigen or have a positive PCR test for active hepatitis B virus will NOT be allowed to participate in the study.
• Has HbA1c ≥ 6.5 % or fasting glucose ≥126.0 mg/dL. (either test can be used to establish eligibility).

Egyéb

• Females who are pregnant, breastfeeding or plan to become pregnant.
• Plan for blood donations during the study and within 30 days following completion of or early discontinuation from the trial.
• Has Clinically significant ECG abnormalities on ECG at Screening

• Male or female aged between 18-65 years of age, inclusive at the time of consent.
• Have a body mass index (BMI) of 30.0 to 45.0 kg/m\^2 (inclusive) at screening.
• Female subjects must have a negative urine pregnancy test at screening, if of childbearing potential or be of non-childbearing potential. If the urine test is positive or cannot be confirmed as negative, then the subject must have a negative serum pregnancy test (hCG). Non-childbearing potential is defined as (by other than medical reasons):
  • Age ≥ 50 years, no menses for at least one year, per subject self-report.
  • Documented hysterectomy, bilateral tubal ligation, or bilateral oophorectomy.
• For female subjects who are Women of childbearing potential (WOCBP), subject must agree to abstain from heterosexual intercourse or use a highly effective contraceptive(s) (with a failure rate of <1% per year), as described in the protocol, during the treatment and follow-up and for at least 90 days after the last dose of bremelanotide. Hormonal-based contraception is to be employed for a minimum of 28 days prior to Day 0. Oral hormonal contraceptives should be combined estrogen and progesterone. If a progesterone-only oral contraceptive is used, then a second method of birth control should be used as well. Acceptable forms of contraception include:
  • Surgical sterilization of the subject or male partner;
  • FDA- or Health Canada-approved female hormonal contraceptives;
  • An IUD;
  • Essure® (transcervical sterilization);
  • "Double-barrier" contraception defined as:
  • condom + spermicide, or
  • condom + diaphragm (which is used with a spermicide).
• Female subjects must agree not to donate eggs (ova, oocytes) for any purpose during the treatment and follow-up and for at least 30 days after the last dose of BMT.
• Male subjects must agree to abstain from heterosexual intercourse or use double barrier protection with condom and spermicide with any WOCBP sexual partner from screening and continuing for at least 30 days after the last dose of BMT:
  • Alternatively, documented sterilization confirmed by the absence of sperm in the ejaculate or ≥ one-year post-operative from vasectomy.
• Male subjects must agree not to donate sperm for at least 30 days after the last dose of BMT.
• Subjects must be willing to self-inject.
• Subjects must have the ability to complete the study in compliance with the protocol and all instructions.
• Subjects must have the ability to understand and provide written informed consent.
