• Intervention Model: SEQUENTIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

ORT247

Single ascending dose of intravenous ORT247 administered as a infusion over 60 minutes. Subjects enrolled into 1 of 5 planned cohorts will receive 75mg, 150mg, 300mg, 600mg, and 1200mg with dosing being conducted in a staggered fashion, separated by at least 30 minutes of an infusion in one subject and the start of an infusion in another subject.

Group Type: EXPERIMENTAL

ORT247

Intervention Type: DRUG

ORT247 will be provided to study sites in single-use, sterile vials for infusion. Each dose will be prepared with normal saline for infusion.

Placebo

Single intravenous dose of vehicle with dosing being conducted in a staggered fashion, separated by at least 30 minutes of an infusion in one subject and the start of an infusion in another subject.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

Placebo consists of normal saline

Female subjects of childbearing potential who are heterosexual must agree to use a method of contraception considered to be highly effective (i.e., results in <1% failure rate when used consistently and correctly) from screening through 120 days after the last dose of study drug

2. Female subjects of non-childbearing potential must have evidence from their medical history indicating that they are not of childbearing potential and must not currently be breastfeeding.

• Any non-vasectomized male subjects must have agreed to use barrier contraceptives plus spermicide for 200 days after dosing.
• Male subjects must agree not to donate sperm for 200 days after dosing
• Female subjects must agree not to preserve eggs (ova) for 120 days after dosing
• Has not participated in a clinical drug study within 30 days of study start, or within 5 half-lives, unless study blind has been broken and the subject was known to be on placebo

• Any significant acute or chronic medical illness
• Any history of cancer within 5 years of enrollment with the exception of resected skin basal cell carcinoma
• Any major surgery within 4 weeks of study drug administration
• Donation of blood or serum >500 mL to a blood bank or in a clinical study (except screening visit) within 3 months of study drug administration
• Inability to undergo venipuncture or tolerate venous access
• Has smoked or used tobacco products within 3 months before study drug administration
• Positive drug screen for alcohol, drugs of abuse, or tobacco
• Recent (within 6 months of study drug administration) drug or alcohol abuse as defined in Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-V), Diagnostic Criteria for Drug and Alcohol Abuse
• Evidence of any clinically significant neurological or psychiatric disorder that could interfere with study assessments as determined by investigator and sponsor
• History of or currently has schizophrenia, schizoaffective disorder or bipolar disorder, untreated major depression (DSM-V or International Statistical Classification of Diseases and Related Health Problems, 10th edition [ICD-10] criteria)
• Significant illness or infection requiring intervention within the prior 30 days as determined by investigator and sponsor (must test negative for active coronavirus disease 2019 [COVID-19])
• Indication of potential suicidality risk
• Any of the following abnormalities at screening: serum creatinine > upper limit of normal (ULN), hepatic transaminases (aspartate aminotransferase or alanine aminotransferase) > ULN, abnormal blood pressure based on the clinical judgment of the investigator, QTcF >470 msec
• Known history of hypersensitivity to any component of the ORT247 drug product or placebo
• Currently taking, or planning to take, any medication (prescription or over-the-counter) that would potentially affect the assessment of pharmacokinetics (PK), pharmacodynamics (PD), or immunogenicity of ORT247.
