Adverse events (AEs) are defined as any untoward medical occurrence regardless of its causal relationship to study treatment. Number of participants with an AE are summarized by MedDRA System Organ Class (SOC). Each subject was counted once per SOC. If a condition was present at screening, it was not considered an AE unless the severity worsened.

Laboratory parameters and associated thresholds include albumin <=3.4 g/dL, glucose <= 69 mg/dL or >=106 mg/dL, blood urea nitrogen (BUN) >= 21 mg/dL, potassium >=5.2 mEq/L or <=3.4 mEq/L, calcium < 8.7 mg/dL or >=10.3 mg/dL, sodium <=132 mEq/L or >=144 mEq/L, total protein <=5.9 g/dL, creatinine >=1.3 mg/dL (male) or >= 1.0 mg/dL (female), creatine phosphokinase >= 308 U/L (male) or >=192 U/L (female), phosphorus <=2.4 mg/dL, alkaline phosphatase >= 130 IU/L (males) or >= 105 IU/L (female), aspartate aminotransferase >= 39.9 U/L (male) or >= 31.9 U/L (female), alanine aminotransferase >=40.9 U/L (male) or >= 32.9 U/L (female), total bilirubin >=1.2 mg/dL, direct bilirubin >=0.2 mg/dL, magnesium <=1.6 mg/dL, and serum cortisol <= 4 ug/dL. If a clinical chemistry laboratory value met the threshold for an AE at baseline, subsequent safety laboratory results were only considered to be an AE if the grading worsened in severity.
Number of Participants With Abnormal Hematology Laboratory Toxicity Results
Laboratory parameters and associated thresholds for adverse events include hemoglobin <= 12.2 g/dL (male) or <= 10.8 g/dL (female), hematocrit <= 36.1 % (male) or <= 32.6 % (female), lymphocyte count <= 799 cell/mm3, neutrophil count <= 1,299 cell/mm3 (African Americans) or <= 1,699 cell/mm3 (all others), monocyte count >= 1001 cell/mm3, eosinophil count >= 871 cell/mm3, basophil count >= 101 cell/mm3, platelet count <= 150 x 10^3/mm3, red blood cell (RBC) count <= 4.1 x 10^6/uL (male) or <= 3.7 x 10^6/uL (female), and white blood cell (WBC) count >= 9,001 cell/mm3 or <= 2,499 cell/mm3 (African American Males) or >= 11,001 cell/mm3 or <= 2,499 cell/mm3 (African American Females) or >= 10,001 cell/mm3 or <= 3,999 cell/mm3 (all others).

Laboratory parameters include prothrombin time (PT), activated partial prothrombin time (PTT), and prothrombin international normalized ratio (INR). Thresholds for adverse events were considered as PT >= 11.6 s, PTT >= 30.1 s, INR >= 1.2. If a coagulation laboratory value met the threshold for an AE at baseline, subsequent safety laboratory results were only considered to be an AE if the grading worsened in severity.
Number of Participants With Abnormal Urinalysis Laboratory Toxicity Results
The only graded urinalysis laboratory parameter was red blood cells (RBC) by complete urinalysis. The threshold for adverse events was considered as >=3. If a urinalysis laboratory value met the threshold for an AE at baseline, subsequent safety laboratory results were only considered to be an AE if the grading worsened in severity.
Number of Participants With Abnormal Electrocardiogram (ECG) Toxicity Results
Each participant is only counted once per toxicity grade for the worst severity recorded. The only ECG parameter graded was QTcF interval with a threshold of >= 30 msec. If an ECG value met the threshold for an AE at baseline, subsequent safety ECG results were only considered to be an AE if the grading worsened in severity.
Number of Participants With Abnormal Vital Signs
Each participant is only counted once per toxicity grade for the worst severity recorded. Vital sign parameters include systolic blood pressure (BP), diastolic BP, pulse, respiratory rate, and temperature. Thresholds for abnormal vital signs were considered as systolic BP >= 141 mmHg or <= 89 mmHg, diastolic BP >= 91 mmHg, pulse <= 54 bpm (baseline > 60 bpm) or <=50 (baseline <= 60 bpm) or >= 101 bpm, respiratory rate >= 17 breaths per minute, and temperature >= 38.0 degrees Celsius. If a vital sign result met the threshold for an AE at baseline, subsequent vital sign results were only considered to be an AE if the grading worsened in severity.

5. Study Description

Brief Summary
This is a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose study in healthy adult subjects ages 18 - 45 years inclusive. It is designed to evaluate the safety and PK of single oral doses of VT-1598. Forty-eight subjects will be enrolled in the study at 1 site in the US and randomized to receive either VT-1598 or placebo in 6 dosage cohorts (five fasted cohorts and one fed cohort). Each cohort will have 8 subjects; 6 subjects will receive a single oral dose of VT-1598 and 2 subjects will receive matching placebo. Cohorts 1 - 5 will include 2 sentinel subjects randomized to different treatments. Cohort 6 (receiving treatment after being fed a high-calorie, high-fat meal) will not include sentinel subjects. Subjects will be admitted to the study site before dosing and remain at the study site for safety monitoring and PK assessments for at least 72 hours post-dose. Subjects will return to the study site on study Days 7, 14, and 21 for outpatient safety monitoring and PK assessments. There are no formal hypotheses being tested in this Phase 1 trial study. The primary objectives of this study are 1) to determine the safety of single-ascending oral doses of VT-1598 in healthy adult subjects in a fasted state, and 2) to determine the safety of single oral dose of VT-1598 in healthy adult subjects in a fed state.
Detailed Description
This is a Phase 1, randomized, double-blind, placebo-controlled, single ascending dose study in healthy adult subjects ages 18 - 45 years inclusive. It is designed to evaluate the safety and PK of single oral doses of VT-1598. Forty-eight subjects will be enrolled in the study at 1 site in the US and randomized to receive either VT-1598 or placebo in 6 dosage cohorts (five fasted cohorts and one fed cohort). Cohorts 1 - 4 will run sequentially, but Cohorts 5 and 6 may be started concurrently. Each cohort will have 8 subjects; 6 subjects will receive a single oral dose of VT-1598 and 2 subjects will receive matching placebo. Cohorts 1 - 5 will include 2 sentinel subjects randomized to different treatments. Cohort 6 (receiving treatment after being fed a high-calorie, high-fat meal) will not include sentinel subjects. VT-1598 will be administered in the following escalation schedule: Cohort 1 will receive 40 mg dose, Cohort 2 will receive 80 mg dose, Cohort 3 will receive 160 mg dose, Cohort 4 will receive 320 mg dose, Cohort 5 will receive 640 mg dose, and Cohort 6 (fed cohort) will receive 160 mg dose. Subjects will be admitted to the study site before dosing and remain at the study site for safety monitoring and PK assessments for at least 72 hours post-dose. Subjects will return to the study site on study Days 7, 14, and 21 for outpatient safety monitoring and PK assessments. There are no formal hypotheses being tested in this Phase 1 trial study. The primary objectives of this study are 1) to determine the safety of single-ascending oral doses of VT-1598 in healthy adult subjects in a fasted state, and 2) to determine the safety of single oral dose of VT-1598 in healthy adult subjects in a fed state. The secondary objectives of this study are 1) to determine the pharmacokinetic (PK) profile in plasma and urine of VT-1598 and its primary metabolite, VT-11134, in healthy adult subjects, and 2) to determine the effect of a high-fat, high-calorie meal on the PK profile of VT-1598 and VT-11134 when a single oral dose of VT-1598 is given.

Each participant is only counted once per toxicity grade for the worst severity recorded. The only ECG parameter graded was QTcF interval with a threshold of >= 30 msec. If an ECG value met the threshold for an AE at baseline, subsequent safety ECG results were only considered to be an AE if the grading worsened in severity.
Time Frame
Day 1 through Day 21
Title
Number of Participants With Abnormal Vital Signs
Description
Each participant is only counted once per toxicity grade for the worst severity recorded. Vital sign parameters include systolic blood pressure (BP), diastolic BP, pulse, respiratory rate, and temperature. Thresholds for abnormal vital signs were considered as systolic BP >= 141 mmHg or <= 89 mmHg, diastolic BP >= 91 mmHg, pulse <= 54 bpm (baseline > 60 bpm) or <=50 (baseline <= 60 bpm) or >= 101 bpm, respiratory rate >= 17 breaths per minute, and temperature >= 38.0 degrees Celsius. If a vital sign result met the threshold for an AE at baseline, subsequent vital sign results were only considered to be an AE if the grading worsened in severity.
