About
This is a prospective, randomized, double-blind, placebo-controlled study designed to assess the safety and efficacy of bremelanotide (BMT) used in combination with tirzepatide therapy in the treatment of obesity in subjects with a BMI ranging from 30.0 to 45.0 kg/m2 (inclusive).
Full description
A total of approximately 60 subjects at approximately five to eight (5-8) centers within the United States (US), will be enrolled into the study for 8 weeks of treatment. Subjects who provide written informed consent and meet all initial eligibility criteria will enter into Screening. The subjects' historical and current medical data will be collected, reviewed, and recorded to be used as baseline values.
Enrolled subjects will begin the study and go through 2 treatment periods:

Volunteers
Inclusion criteria
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 patient must have a negative serum pregnancy test (hCG). Non-childbearing potential is defined as (by other than medical reasons):
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:
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:
a. 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.
Exclusion criteria
Females who are pregnant, breastfeeding or plan to become pregnant.
Have a known allergy or intolerance to Melanocortin peptides.
Subjects with a positive Serum Antigen/Antibody Hepatitis Panel (Hep B and C) and HIV antibody test Human Immunodeficiency Virus (HIV) antibody.
Note: Patient with positive hepatitis C antibody but negative PCR test for active Hepatitis C viral shedding will be allowed to participate in the study. Patients with a positive Hepatitis B surface antigen antibody or core antigen antibody will be allowed to participate in the study. Patients 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.
Patients with active alcohol dependence and/or drug use (with Cannabis exception) that would compromise compliance on the study as determined by the Investigator.
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 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 patient 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 HbA1c ≥ 6.5 % or fasting glucose ≥126.0 mg/dL.
Has type 1 diabetes.
Has taken any experimental drug or therapy within 28 days / 5 half-lives of trial treatment or concurrently participating in another clinical trial.
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.
Plan for blood donations during the study and within 30 days following completion of or early discontinuation from the trial.
Planned bariatric surgery or planned major surgeries during the study time period.
Has personal or family history of MEN 2 syndromes or Medullary Thyroid Cancer.
Prior hypersensitivity to tirzepatide component.
Has hypertension (by medical history or by screening vital signs) and/or known cardiovascular disease
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
Has a diagnosis of type 2 diabetes
Has Clinically significant ECG abnormalities on ECG at Screening
