Brief summary: This study will be conducted in healthy male or female subjects using a double-blind, randomized, placebo-controlled, single-dose design. Up to 30 subjects will be enrolled; 3 healthy subjects in Cohorts 1 and 2 (2 active, 1 placebo) and 8 healthy subjects in Cohorts 3 to 5 (6 active, 2 placebo). The following CPSI-2364 doses are proposed: 1 mg, 10 mg, 30 mg, 90 mg, and 270 mg.Safety will be evaluated throughout the study and include physical examinations, vital signs assessments, 12-lead electrocardiograms (ECGs), routine clinical laboratory tests (including blood chemistry, hematology, coagulation, and urinalysis), and adverse event (AE) assessments. Vital sign assessments and 12-lead ECGs will be performed repeatedly over the 24-hour observation period. Venous blood samples will be taken at specified intervals and tested for the presence of CPSI-2364.

Detailed description: This study will be conducted in healthy male or female subjects using a double-blind, randomized, placebo-controlled, single-dose design. Up to 30 subjects will be enrolled; 3 healthy subjects in Cohorts 1 and 2 (2 active, 1 placebo) and 8 healthy subjects in Cohorts 3 to 5 (6 active, 2 placebo). The following CPSI-2364 doses are proposed: 1 mg, 10 mg, 30 mg, 90 mg, and 270 mg. In Cohort 1 (1 mg) and Cohort 2 (10 mg), the three subjects will all be dosed on the same day, with at least 60 minute intervals between dosing. In Cohorts 3 to 5, the first two subjects of each cohort (one active, one placebo) will receive their drug on the same day with at least a 60-minute interval between dosing, with the remainder of the cohort being dosed the next day once these subjects have been assessed. Safety labs, physical examination findings, and adverse events available up to and including Day 5 data of each cohort will be reviewed by the Investigator, the Study Manager, and the Sponsor (or designee) in order to determine the progression of dose escalation. Subjects will not be enrolled in the next higher cohort until the dose in the preceding cohort is deemed safe and tolerable. Doses will continue to be escalated in subsequent groups until a maximum tolerated dose (MTD) is reached, or until a top dose of 270 mg is reached, whichever is sooner. Intermediate and repeat dose levels may be administered in addition to or in place of the planned dose levels, if it is deemed appropriate to increase the safety or scientific value of this Phase 1 exploratory study.Safety will be evaluated throughout the study and include physical examinations, vital signs assessments, 12-lead electrocardiograms (ECGs), routine clinical laboratory tests (including blood chemistry, hematology, coagulation, and urinalysis), and adverse event (AE) assessments. Vital sign assessments and 12-lead ECGs will be performed repeatedly over the 24-hour observation period.Venous blood samples will be taken at specified intervals and tested for the presence of CPSI-2364.

Eligibility criteria: Inclusion Criteria:

Subjects meeting all of the following criteria will be considered for admission to the study:

* male or female between 18 and 55 years old inclusive;
* for females, the following conditions are to be met: all female subjects must be confirmed as not pregnant via serum pregnancy test; females must be of non-childbearing potential (defined as either surgically sterile or at least 1 year postmenopausal); or female subjects of childbearing potential must use 2 of the 3 following acceptable birth control methods from the time specified prior to the study through 60 days following the last dose of study drug: intrauterine contraceptive device (IUD) in place for at least 2 months prior to study; barrier method (condom or diaphragm) with spermicide for at least 14 days prior to screening; stable hormonal contraceptive for at least 3 months prior to study;
* in good health as determined by the Investigator based on medical history, physical examination, ECG, and clinical laboratory tests;
* with a body mass index (BMI) of 19 to 30 kg/m2, inclusive;
* nonsmokers (refrained from any tobacco usage, including smokeless tobacco, nicotine patches, etc., for 6 months prior to the administration of the study medication), subjects must have nicotine levels below those measured for smokers (less than 400 ng/mL);
* agrees to abstain from alcohol intake 48 hours before each administration of study agent and during inpatient portion of the study (Days -1 to 2);
* agrees to limit caffeine/methylxanthine (e.g., coffee, tea, chocolate, or caffeine-containing soft drinks) intake to less than 300 mg/day for the duration of the study (300 mg of caffeine is equal to approximately 3 cups of coffee or 6 cola drinks);
* agrees not to consume food or beverages containing grapefruit juice, Seville oranges, or quinine (e.g., tonic water) from 72 hours prior to study Day -1 until after the last PK sample is collected;
* capable of understanding and complying with the protocol; willing and able to adhere to the study visit schedule and other protocol requirements;

* abnormal clinical laboratory evaluations, particularly abnormal creatinine, calculated GFR (abnormal defined as \> 60 mL/min), and liver function tests. (Minor excursions from the normal range may be allowed if the clinical picture is otherwise normal and they are considered clinically insignificant by the Investigator and Sponsor \[or designee\]) ;
