Evaluate the Effects of Itraconazole and Ciprofloxacin on Single-Dose PK of Pracinostat in Healthy Nonsmoking Subjects
Study Details
Study Description
Brief Summary
This study is designed as a 2-part, open-label study to assess the effect of pracinostat with itraconazole (part 1) and pracinostat with ciprofloxacin (part 2) on the bioavailability of pracinostat. Secondarily to evaluate the safety and tolerability of pracinostat administered with itraconazole or ciprofloxacin.

Outcome Measures
Primary Outcome Measures
- Peak plasma concentration Cmax in healthy nonsmoking subjects given a single-dose of pracinostat [pre-dose, 0.25, 0.5, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, 72, 96 hours]
Plasma PK parameter Cmax to describe bioavailability of pracinostat
Secondary Outcome Measures
- Number of participants with Adverse Events as a measure of safety and tolerability of single-dose pracinostat when administered with itraconazole or with ciprofloxacin in healthy nonsmoking adult subjects. [1 month]
Safety will be monitored through physical examinations, vital sign measurements, electrocardiograms, adverse events, and clinical laboratory tests.
- Peak plasma PK concentration Area Under the Curve (AUC)AUC 0-t, AUC 0-inf in healthy nonsmoking subjects given a single dose of pracinostat [pre-dose, 0.25, 0.5, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 16, 24, 36, 48, 72, 96 hours]
Plasma PK parameter AUC 0-t, AUC 0-inf for pracinostat

-
A non vasectomized, male subject must agree to use a condom with spermicide or abstain from sexual intercourse during the study until 90 days beyond the last dose of study medication.
-
Understands the study procedures in the informed consent form (ICF), and be willing and able to comply with the protocol.
Exclusion Criteria:
-
Subject is mentally or legally incapacitated or has significant emotional problems at the time of screening visit or expected during the conduct of the study.
-
History or presence of clinically significant medical or psychiatric condition or disease in the opinion of the PI.
-
History of any illness that, in the opinion of the PI, might confound the results of the study or poses an additional risk to the subject by their participation in the study.
-
History or presence of alcoholism or drug abuse within the past 2 years prior to screening.
-
History or presence of hypersensitivity or idiosyncratic reaction to the study medication or related compounds.
-
History of prolonged QT syndrome or require any current medications which may prolong QTc.
-
History or presence of:
-
myasthenia gravis;
-
convulsions.
-
Female subjects who are pregnant or lactating.
-
Positive urine cotinine, drug and alcohol results at screening or check-in.
-
Positive results at screening for HIV, HBsAg or HCV.
-
Seated blood pressure is less than 90/40 mgHg or greater than 140/90 mmHg at screening.
-
Seated heart rate is lower than 40 bpm or higher than 99 bpm at screening.
-
QTcF interval, is >430 msec (males) or >450 msec (females) or deemed clinical abnormal by the PI at screening or prior to dosing.
-
Unable to refrain from or anticipates the use of:
-
Any drug, including prescription and non-prescription medications, tobacco, antacids, herbal remedies, or vitamin supplements beginning approximately 14 days prior to the first dose of study medication and throughout the study. Hormone replacement therapy will be allowed if postmenopausal females are on a stable treatment for at least 1 month prior to dosing on Day 1 of Period 1. Acetaminophen (up to 2 g per 24 hour period) may be permitted during the study.
-
