Eligibility Criteria

• Age: 18 Years - 45 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy volunteers (Participants) will be eligible for enrollment in the study only if they meet ALL the following criteria at time of Screening and pre-dosing:
• Healthy male or female between the ages of 18 and 45 years (inclusive) at the time of Screening. Healthy status will be determined by the Investigator based on medical history, clinical laboratory results, vital sign and electrocardiogram measurements, and physical examination at screening.
• Willingness and ability to give personal signed informed consent and comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures.
• Weight of at least 45 kg and a body mass index (BMI) ≥ 19.0 and ≤ 32.0 kg/m2 at Screening.
• Male participants who are non-sterilized and sexually active with a female partner of childbearing potential must agree to use adequate contraception from the signing of informed consent, throughout the duration of the study, and for 90 days after completion of the study. Male participants must use barrier contraception (e.g., condom). In addition to the male participant using a condom, the female partner of childbearing potential must also be using a highly effective form of contraception (hormonal or non-hormonal). The male participant must be advised and agree not to donate sperm during this period.
• Female participants of childbearing potential who are sexually active with a non-sterilized male partner must agree to routinely use highly effective contraception from signing of informed consent, throughout the duration of the study, and for 30 days after completion of the study. A highly effective method of contraception for women of childbearing potential is defined as one that has no higher than a 1% failure rate per year. The acceptable methods of contraception are:
• Intrauterine device (IUD), Bilateral tubal occlusion, Vasectomised partner (provided that the partner(s) absence of sperm in the ejaculate has been confirmed and documented), and Sexual abstinence (if it is the preferred and usual lifestyle of the participant).

You may not qualify if:

• Participants meeting ANY of the following criteria at time of Screening and/or pre-dosing will be excluded from enrollment:
• Any concomitant disease, condition, or treatment that could interfere with the conduct of the study, or that would, in the opinion of the Investigator or Sponsor, pose an unacceptable risk to the participant in the study or interfere with the interpretation of study data.
• Has received any investigational compound within 30 days or 5 half-lives, whichever is longer, prior to the first dose of study drug.
• Participant who is a study site employee or who is an immediate family member of a study site employee, (e.g., spouse, parent, child, sibling). Any participant under duress during the consent process.
• Participant has any clinically significant illness, such as cardiovascular, neurologic, pulmonary, hepatic, renal (estimated or actual GFR less than 90 mL/minute), metabolic, gastrointestinal, urologic, immunologic, endocrine, or psychiatric disease or disorder, or other abnormality, which may affect safety, or potentially confound the study results. It is the responsibility of the Investigator to assess the clinical significance; however, consultation with the Sponsor and/or CRO MM may be warranted.
• Participant has a known hypersensitivity to any component of the formulation of BF844.
• Participant has a positive urine result for drugs of abuse (defined as any illicit drug use) at Screening or Check-in (Day -1).
• Participant who, in the opinion of the Investigator, has a history of excessive alcohol or drug abuse within one year of Screening.
• Use of or plans to use medications (e.g., S-warfarin, NSAIDs, phenytoin, omeprazole, and clopidogrel) that are significantly metabolized by CYP2C19/ CYP2C9. Additionally, the use of any medications that could have a significant impact on organ function (e.g., barbiturates, omeprazole, and cimetidine). These drugs are prohibited during the study and within 5 half-lives of the individual agent or within 28 days (whichever is longer) prior to enrollment.
• Use or intended use of prescription or non-prescription medications (including vitamins or supplements) from 7 days prior to dosing or 5 half-lives (whichever is greater), unless the Investigator or medical delegate considers that such use would not significantly impact participant safety or study data.
• Participant is pregnant or lactating or intending to become pregnant before, during, or within 30 days since the last dose of the study drug; or intending to donate ova during such time.
• If male, the participant intends to donate sperm during the course of this study or within 90 days after the last dose of the study drug.
• Participant has current or recent (within 6 months) gastrointestinal disease that would be expected to influence the absorption of drugs (i.e., a history of malabsorption, any surgical intervention known to impact absorption \[e.g., bariatric surgery or bowel resection\], esophageal reflux, peptic ulcer disease, erosive esophagitis, or frequent \[more than once per week\] occurrence of heartburn).
• Participant has a positive test result for: (i) hepatitis B surface antigen (HBsAg), (ii) hepatitis C virus (HCV) antibody, or (iii) human immunodeficiency virus (HIV) infection at Screening.
• Participant has used nicotine-containing products (including but not limited to cigarettes, pipes, cigars, chewing tobacco, nicotine patches, or nicotine gum) within 28 days prior to Check-in (Day -1). The cotinine test is positive at Screening or Check-in (Day -1) or if the participant is unwilling to abstain from nicotine-containing products throughout the study.

Model Details: This is a first-in-human, single center, randomized, double-blinded, single and multiple ascending doses (SAD and MAD) and food effect Phase I study in healthy adult volunteers (HV). The SAD cohorts will consist of five cohorts of eight participants (6 randomized to treatment + 2 randomized to placebo) in each cohort (Total 40 HV). Additional cohorts may be added. The food effect (FE) cohort will consist of 12 participants who receive a single dose of BF844 in a cross-over manner. Each participants will receive the same single dose of BF844 under two separate conditions: one after an overnight fast, and the second following a high-fat breakfast 30 minutes prior to dosing. The MAD cohorts will consist of 3 cohorts of eight participants (6 randomized to treatment + 2 randomized to placebo) in each cohort (Total 24 HV). The subjects in MAD cohorts will be dosed once daily for 7 consecutive days. Additional cohorts may be added.
