Who can join

Age: 18 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Male or female subjects 18 to 55 years of age, inclusive, at the time of signing the informed consent form (ICF).
• Subjects must be in generally reasonable health with clinically insignificant screening and admission results (medical history, 12-lead electrocardiogram [ECG], physical examination, and laboratory tests), as determined by the Investigator.
• Subjects must have a body mass index (BMI) >18 kg/m2 or <32 kg/m2
• Subjects must have aspartate transaminase (AST), alanine transaminase (ALT), total bilirubin (TBIL), alkaline phosphatase (ALP), and glucose within upper limit of normal (ULN) range per reference laboratory reference ranges at Screening and Day -1 (Admission); one repeat laboratory analysis allowed per Investigator discretion.
• Women of childbearing potential must have a negative serum pregnancy test at Screening and negative urine pregnancy test at Day -1 (Admission), must not be actively breastfeeding, or planning to become pregnant during the study, and if not practicing abstinence from heterosexual activity that could result in conception (if this is the preferred and usual lifestyle of the subject), must agree to use 2 approved methods of birth control, during the study and for at least 60 days after the last dose of study drug, from the list below:
• Condom plus diaphragm.
• Condom plus cervical cap or female condom.
• Hormonal contraceptives (stable dose for 28 days [4 weeks] prior to Screening) plus condom.
• Intrauterine device (in place for 28 days [4 weeks] prior to Screening) plus condom.
• Condom plus spermicide.
• Partner vasectomy and use of barrier contraception methods (e.g., male condom, diaphragm, or sponge with spermicide).
• Women of nonchildbearing potential must be either surgically sterile (hysterectomy, bilateral oophorectomy, or bilateral tubal ligation/salpingectomy) or >1 year postmenopausal with follicle-stimulating hormone (FSH) in the postmenopausal range and not actively breastfeeding.
• Men must agree to use barrier contraception (condom with spermicide) and refrain from sperm donation from the first dose of study drug until at least 90 days after the last dose of study drug. Post vasectomy, men must agree to use a barrier method (or partner barrier method) from the first dose of study drug until at least 90 days after the last dose of study drug.
• Subjects must be informed of the nature of the study and must have agreed to and be able to read, review, and sign the study ICF prior to any study related procedure being performed.

You may not qualify if…

• Current or previous cancer, excluding basal cell carcinoma that has been in remission for >5 years prior to dosing and in situ cervical carcinoma; diabetes or known diagnosis of prediabetes; or any clinically significant cardiovascular (including ECG disturbances or history of rhythm disturbance/abnormality), endocrine, renal, hepatic, gastrointestinal, hematologic, respiratory, dermatological, neurological, psychiatric, or other disorder.
• Hypertension, defined as blood pressure >140/90 mmHg (2 separate readings at least 15 minutes apart if first reading is not within normal range).
• a. NOTE: For the Screening blood pressure measurement, subjects should avoid smoking, caffeine, or exercise within 30 minutes prior to measurement; empty his or her bladder; then sit quietly in a comfortable chair with back support for at least 5 minutes prior to blood pressure measurement; and remain still during the measurement. Blood pressure should be measured with the subject's limb supported, with the blood pressure cuff at heart level, and with the correct cuff size. The measurement should not be taken over clothes.
• Hyperlipidemia defined as
• Cholesterol >300 mg/dL.
• Low-density lipoprotein cholesterol >190 mg/dL.
• And/or triglycerides >500 mg/dL. Note: Abnormal laboratory values may be repeated once at Investigator discretion.
• Hemoglobin A1c (HbA1c) >6.5% at Screening. Note: Abnormal laboratory values may be repeated once at Investigator discretion.
• Hemoglobin or hematocrit outside upper and lower limits of normal range per reference laboratory range at both Screening and Day -1 (Admission).
• Creatinine kinase (CK) > ULN at Screening and Day-1 (Admission).
• Serum creatinine above upper limit of normal range per reference laboratory reference ranges at both Screening and Day -1 (Admission). Note: Abnormal laboratory values may be repeated once at Investigator discretion.
• Estimated glomerular filtration rate < 90 mL/min/1.73 m2 (calculated using the Chronic Kidney Disease Epidemiology Collaboration equation) at Screening and Day-1 (Admission). One retest of the exclusionary eGFR value is allowed at the discretion of the Investigator.
• Known sensitivity or allergies to Trehalose; history of severe hypersensitivity to IV infusion.
• Unwillingness to abstain from alcohol for 72 hours prior to dosing through EOS/ET.
• Use of prescription or nonprescription drugs (excluding hormonal contraceptives), if clinically applicable, including vitamins, supplements, herbal preparations, and medicines that prolong QT/QTc within 7 days or 5 times longer than the half-life (whichever is longer) prior to the first dose of study drug through EOS (approximately 60 days).
• Blood or plasma donation within 60 days prior to dosing.
• Use of live and non-live vaccine within 30 days prior to the first dose of study drug or an intention to receive such a vaccine at any time during the study.
• Received an investigational agent in another clinical study within 30 days prior to the first dose of study drug, or within 10 times longer than the half-life of the compound with which the subject was treated, whichever is longer.
• Positive results of any of the virology tests (human immunodeficiency virus (HIV test), hepatitis B virus (HBsAg test) or hepatitis C virus (hepatitis C antibody test).
• Diagnosed to be COVID-19 positive by polymerase chain reaction testing (SARS CoV 2 RT PCR positive) of a respiratory specimen (preferably a nasopharyngeal swab) on Day -2.
• NOTE: Rapid Antigen Test may be used if PCR testing is unavailable
• Personal or family history of vascular aneurysms and disorders.
• Personal or family history of long QT syndrome.
• Personal or family history of hypokalemia.
• Corrected QT interval using Fridericia's formula (> 450 msec) based on the average of triplicate ECGs.
