Study of BMF-219 in Healthy Adult Subjects and in Adult Subjects With Type 2 Diabetes Mellitus (T2DM)

Inclusion Criteria: Healthy Subject: Males or females, age ≥18 and ≤65 years. BMI ≥18 and ≤35 kg/m2. Subjects are healthy on the basis of their medical history, physical examination, ECG, and routine laboratory data. Females are to be not pregnant, non-lactating, and can be postmenopausal (defined as amenorrheic for at least 1 year while not taking oral contraceptives [OCPs] without an alternative cause). Females of childbearing potential must have a negative pregnancy test at screening and be willing to have additional pregnancy tests during the study. They must also agree to commit to either continued abstinence from engaging in reproductive sexual activity or to use 2 adequate forms of contraception methods simultaneously from the time of giving informed consent until 90 days after the last dose of investigational product to avoid pregnancy. Adequate contraception is defined as oral, intravaginal, transdermal, implantable or injectable contraceptives, intrauterine devices, surgical sterilization (achieved through hysterectomy, oophorectomy, bilateral salpingectomy or tubal ligation) in addition to an intrauterine hormone-releasing system (IUS) and/or spermicide. Females must be willing to refrain from egg donation, and in vitro fertilization during treatment and until the end of contraception requirement. If needed, female subjects should be advised to seek advice about egg donation and cryopreservation of germs cells before treatment. Males with partners who are female with reproductive potential must agree to commit to either continued abstinence from sexual intercourse or that they or their partners will use at least 2 effective contraceptive methods when engaging in reproductive sexual activity throughout the study and will avoid conceiving for 90 days after the last dose of BMF-219. Males must be willing to refrain from sperm donation during treatment and until the end of contraception requirement. If needed, male subjects should be advised to seek advice about sperm donation and cryopreservation of germ cells before treatment All subjects must be willing and able to provide written, signed informed consent and be willing and able to comply with all study procedures and tests. Subjects with T2DM: Males or females, age ≥18 and ≤65 years. Diagnosed with T2DM within the last 15 years. Treated with lifestyle management with or without at the most 3 anti-diabetic medications (metformin*, sodium-glucose cotransporter 2 [SGLT2] inhibitor, glucagon-like peptide1 receptor agonists [GLP-1Ra], dipeptidyl peptidase-IV inhibitor [DPP-4I] [alogliptin and sitagliptin only]) with a stable dose for at least 2 months prior to screening. * If on metformin, the subject must be on a minimum stable dose of ≥500mg/day prior to the screening visit. HbA1c ≥7.0% and ≤10% at screening. BMI ≥25 and ≤40 kg/m2. If treated with lipid-lowering therapy, the dose must be stable for at least 30 days prior to screening. Females are to be not pregnant, non-lactating, and can be postmenopausal (defined as amenorrheic for at least 1 year while not taking oral contraceptives [OCPs] without an alternative cause). Females of childbearing potential must have a negative pregnancy test at screening and be willing to have additional pregnancy tests during the study. They must also agree to commit to either continued abstinence from engaging in reproductive sexual activity or to use 2 adequate forms of contraception methods simultaneously from the time of giving informed consent until 90 days after the last dose of investigational product to avoid pregnancy. Adequate contraception is defined as oral, intravaginal, transdermal, implantable or injectable contraceptives, intrauterine devices, surgical sterilization (achieved through hysterectomy, oophorectomy, bilateral salpingectomy or tubal ligation) in addition to an intrauterine hormone-releasing system (IUS) and/or spermicide. Females must be willing to refrain from egg donation, and in vitro fertilization during treatment and until the end of contraception requirement. If needed, female subjects should be advised to seek guidance about egg donation and cryopreservation of germ cells before treatment.
