Eligibility | Inclusion Criteria: 1. Healthy, adult, male or female (non-lactating and not of childbearing potential) subjects age 19 to 55 inclusive. 2. Females must have undergone one of the following sterilization procedures at least 6 months prior to the first dosing: 1. hysteroscopic sterilization 2. bilateral tubal ligation or bilateral salpingectomy 3. hysterectomy 4. bilateral oophorectomy; or be postmenopausal with amenorrhea for at least 1 year prior to the first dosing and follicle-stimulating hormone (FSH) serum levels consistent with postmenopausal status. 3. Good general health, with no significant medical history. Subjects must have no clinically significant abnormalities at screening, and/or before administration of the initial dose of study drug. 4. Body weight = 50 kg at the screening visit. 5. Body Mass Index (BMI) between 18 and 32 kg/m2 inclusive. 6. Laboratory values (clinical chemistry and hematology) within the normal reference range. Deviations from this range may be acceptable if they are considered 'not clinically significant' (NCS) by the PI, however, AST and ALT shall be <1.5x ULN. 7. Males who have not been vasectomized prior to participating in the study must agree to use at least 2 approved methods of contraception, or to abstain from sexual intercourse, from randomization until 90 days after their last dose of VLX-1005 and should refrain from donating sperm during that period. 8. Is a non-smoker and must not have used any nicotine products within three months prior to screening. 9. Able and willing to attend the necessary visits to the study center. Exclusion Criteria: 1. Blood donation or recipient of blood transfusion in previous 12 weeks. 2. History of clinically significant endocrine, neurological, gastrointestinal, cardiovascular, hematological, hepatobiliary, immunological, renal, respiratory, or genitourinary abnormalities or diseases. 3. History of neoplastic disease (with the exception of adequately treated nonmelanomatous skin carcinoma). 4. Mentally or legally incapacitated (e.g. has significant emotional problems at the time of Screening Visit or expected during the conduct of the study, or has a history of a clinically significant psychiatric disorder within the last 5 years). 5. Fever (body temperature >38 C) or symptomatic viral/bacterial infection or use of antibiotics within 2 weeks prior to Screening. 6. Supine resting blood pressure (BP) >140/90 mmHg or heart rate (HR) >100 beats per minute at Screening and at Day -2. 7. Clinically significant abnormality on ECG performed at the Screening Visit or prior to administration of the initial dose of study drug. (Abnormalities include not being in sinus rhythm, IVCD/BBB or QTcF>450 ms for males (470 ms for females)). 8. Out of range (on repeat) testing for coagulation tests. 9. Clinically significant laboratory abnormalities including: Impaired renal function (estimated creatinine clearance (CrCl) of <80 mL/minute based on CrCl = (140-age [years])(body weight [kg])/(72)(serum creatinine [mg/dL])). 10. Positive test for hepatitis C antibody, hepatitis B surface antigen, or human immunodeficiency virus (HIV) antibody at Screening. 11. Participants with a positive toxicology screening panel (urine test including qualitative identification of barbiturates, tetrahydrocannabinol, amphetamines, benzodiazepines, opiates, cocaine, cotinine and ethanol). 12. Participants with a history of substance abuse or dependency or history of recreational IV drug use (by self-declaration).13. Participant has a suspected history of alcohol abuse in the 6 months prior to screening. 14. Use of NSAIDs, aspirin or aspirin-containing medications (and other medications affecting platelet function [for example cilostazol, clopidogrel, ticagrelor, prasugrel, dipyridamole]) in the 14 days prior to dosing with study medication. VerifyNow testing will be performed at check-in to exclude possible use of medications that affect platelet function. 15. Unable to refrain from or anticipates the use of any medications, including prescription and non-prescription drugs and herbal remedies (such as St. John's Wort [Hypericum perforatum]), beginning 14 days (or 5 half-lives, whichever is longer) before administration of the initial dose of study drug and continuing throughout the study until the final study visit. There may be certain medications that are permitted at the discretion of the PI and Sponsor (including paracetamol/acetaminophen, medications for the treatment of AEs following administration of study drug). 16. Subjects who are unlikely to comply with the study protocol or, in the opinion of the PI, would not be a suitable candidate for participation in the study. 17. Have participated in any other investigational drug trial within 30 days of dosing in the present study. |
