Brief Summary
This is a 3-arm, parallel-group, active- and placebo-controlled, double-blind, randomized study, to compare treatment with intravenous custirsen at 640 mg (highest intended therapeutic dose) with plac...
Detailed Description
The effects of custirsen will be evaluated following administration of a single dose following dose-titration period combined with dexamethasone pretreatment. On days -1 and 7, subjects will undergo a...
Eligibility Criteria
Inclusion
- The subject is a man aged 18 through 45 years of age with a body mass index (BMI) of 18 through 30 kg/m2 at screening.
- The subject is in good health as determined by medical history, ECG, vital signs measurements, physical examination, and clinical laboratory tests.
- The subject must be able to understand and comply with the requirements of the study (eg, all medication, dietary, exercise, tobacco, and alcohol restrictions).
- The subject must provide written informed consent to participate in the study after reading the information and consent form, and after having an opportunity to discuss the study with the investigator or delegate.
- Other inclusion criteria apply.
Exclusion
- Exclusion criteria related to ECG findings include the following:
- The subject has an ECG abnormality that may interfere with the accurate assessment of the QT interval, including intraventricular conduction delays (QRS \>120 msec or PR \>200 as measured at the screening and check-in visits) and complete or incomplete bundle branch blocks.
- The subject has a resting QTcF interval of ≤360 msec and/or ≥450 msec measured at screening or day -2.
- Exclusion criteria related to cardiac function include the following:
- The subject has a known clinically significant (in the opinion of the investigator) cardiovascular disorder, including coronary artery disease, valvular heart disease, cardiomyopathies, or an ECG abnormality suggestive of prior myocardial infarction, angina pectoris, chamber enlargement, or hypertrophy. Notwithstanding, subjects with known significant disorders will be excluded.
- The subject has a known clinically significant arrhythmia or rhythm disturbance observed on the screening and/or day -2 12-lead ECG.
- The subject has a supine pulse rate outside of the range of 40 to 100 bpm (following at least a 10-minute rest) measured at screening or day -2.
- The subject has a supine blood pressure outside of the range of 90 to 139 mm Hg systolic or 50 to 89 mm Hg diastolic (following at least a 10-minute rest) measured at screening and on day -2. Note: The blood pressure measurement may be repeated up to 3 times to meet eligibility requirements. In this case, the average of these 3 measurements must meet eligibility criteria.
- The subject reports a history of, or risk factors for, Torsades de Pointes (eg, congestive heart failure, serum electrolyte abnormalities) including a family history of arrhythmia, sudden unexplained death at a young age (before 40 years) in a first-degree relative, or long QT syndrome, or a personal history of syncope.
- The subject has low serum potassium and/or magnesium and/or corrected calcium blood levels (less than 3.5 milliequivalent/liter (mEq/L), 1.8 mEq/L, and 8.9 mg/dL, respectively) at screening and/or day-2.
- The subject has any condition that may possibly interfere with drug absorption, distribution, metabolism, or excretion (eg, previous surgery on the gastrointestinal tract \[including removal of parts of stomach, bowel, liver, gall bladder, or pancreas\] or stomach banding).
- The subject has an abnormality in medical history, physical examination, biochemistry, hematology, coagulation, serology, or urinalysis at the screening or admission visit that is considered clinically significant by the investigator or meets grades 2-4 Common Terminology Criteria for Adverse Events (CTCAE) v.4 criteria, or in the opinion of the investigator, could interfere with the objective of the study or the safety of the subject. Notwithstanding, the following values must remain within the normal range values (as determined by the Physician Reference Laboratory \[PRL\]) in order for a subject to be eligible for the study: calcium, magnesium, potassium, creatinine, ALT, AST, GGT, hemoglobin, absolute lymphocyte count, absolute 50 mg/dL in asymptomatic subjects and absolute leukocyte count values as low as 3.1x109/L in African American subjects will be considered for enrollment at the investigator's discretion. Lastly, the upper limit value for exclusion is modified for the following values and is as follows: INR\>1.2, total bilirubin\>1.2 mg/dL, serum amylase \>143 U/L, LDH\>261 U/L, and CPK\>367 U/L, which do not normalize upon repeat testing, will be exclusionary.
- The subject has used one of the prohibited drugs, substances or foods as follows:
- any investigational product within 60 days (or 5 half-lives, whichever is longer) preceding the study
- any prescription or nonprescription medication (including herbal remedies, vitamins, or dietary supplements) or vaccine within 14 days of the first day of study drug administration (day 1) or within 5 half-lives before the first day of study drug administration, whichever is longer. Exceptions are locally acting medications (eg, topical creams), which are not allowed within 5 days of study drug administration, and the occasional use of acetaminophen (up to 3 g/day) and ibuprofen (up to 1200 mg/day).
- consumption of grapefruit, grapefruit juice, Seville oranges, pomelo-containing products, within the 14 days prior to day -1 and then throughout the entire study
- consumption of excessive amounts of alcoholic beverages, defined as more than 3 drinks per day (beer, wine, or distilled spirits), or unwillingness to comply with the restricted use of alcohol during the study (96 hours prior to admission and until 48 hours after the last study drug administration), history of alcoholism, or evidence of drug/chemical abuse
- positive urine drug (cocaine, amphetamines, barbiturates, opiates, phencyclidine, benzodiazepines, tetrahydrocannabinol), cotinine, or alcohol screen at the screening visit or admission
- consumption of quinine (eg, tonic water) within 7 days prior to admission
- The subject has any other condition, which, in the opinion of the investigator, makes the subject inappropriate for the study.
- Other exclusion criteria apply.
