E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the safety and efficacy profile of ISIS 416858, including
incidence of bleeding and VTE, in patients undergoing total knee
arthroplasty
• to compare the efficacy and safety profile of ISIS 416858 in patients
who achieve </= 0.2 U/mL FXI activity levels tothat of enoxaparin |
|
E.2.2 | Secondary objectives of the trial |
To assess a potential dose-response relationship of ISIS 416858 with
respect to the reduction of VTE incidence in patients undergoing
unilateral total knee arthroplasty |
|
E.2.3 | Trial contains a sub-study | No |

2. Males or Females aged 18 to 80 years old at the time of informed consent
3. Females must be non-pregnant and non-lactating, and either surgically sterile (e.g., tubal occlusion such as bilateral tubal ligation, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or post-menopausal (>12 months since last period). Males must be surgically sterile, abstinent or if engaged in sexual relations of child-bearing potential, the patient must be using an acceptable contraceptive method during and for at least 97 days (approximately 5 half-lives of ISIS 416858) after the last dose of Study Drug.

9. History of clinically significant liver disease in the past year
10. Screening laboratory results as follows, or any other clinically
significant abnormalities in screening laboratory values that would
render a patient unsuitable for inclusion
•Urine protein or blood persistently positive by dipstick. In the event of
positive test results, eligibility may be confirmed with urine microscopy
or 24 hour urine protein measurement as applicable
•ALT or AST >1.5 x ULN
•Total bilirubin >ULN
•Platelet count <150,000 (or history of thrombocytopenia)

•Factor VIII activity, vWF antigen or Ristocetin cofactor activity <0.5
U/mL
•FXI activity <0.3 U/mL
11. Uncontrolled hypertension as judged by the Investigator
12. Hypersensitivity to contrast media
13. Hypersensitivity to enoxaparin or any contraindication listed in the
local labeling of enoxaparin
14. Anticipated concomitant use of anticoagulants/antiplatelet agents
(e.g., dabigatran, rivaroxaban, clopidogrel) or the NSAID nimesulide that
may affect study outcome or any other drug influencing coagulation
(except low dose aspirin and short acting NSAIDs with a half-life <20
hours) at least 7 days before surgery or during treatment with ISIS
416858
15. Treatment with another investigational Drug, biological agent, or
device within one month of screening, or 5 half-lives of study agent,
whichever is longer
16. Treatment with any non-ISIS oligonucleotide (including siRNA) at
any time or prior treatment with an ISIS oligonucleotide within 9
months of screening. Patients that have previously received only a
single dose of an ISIS oligonucleotide as part of a clinical study may be
included as long as a duration ≥4 months elapsed since dosing
17. Recent history of, or current drug or alcohol abuse
18. Active infection (e.g., endocarditis, sepsis) requiring systemic
antiviral or antimicrobial therapy
19. Anticipated use of indwelling intrathecal or epidural catheters
20. Anticipated use of intermittent pneumatic compression devices and
electrical/mechanical muscle stimulators
21. History of or clinically significant abnormal ECG as judged by the
Investigator at Screening
22. Allergy to sulfur containing drugs such as Sultrin, Bactrim (sulfonamide) and captopril, pantoprazole (non-sulfonamide). If
necessary, consult with Sponsor Medical Monitor for concomitant
medication review.
23. Known history of or positive test for human immunodeficiency virus
(HIV), hepatitis C or chronic hepatitis B at Screening
24. Anemia during Screening as judged by the Investigator
25. Unwillingness to comply with study procedures, including follow-up,
as specified by this protocol, or unwillingness to cooperate fully with the
Investigator
26. Have any other conditions, which, in the opinion of the Investigator
would make the patient unsuitable for inclusion, or could interfere with
the patient participating in or completing the study |
