Brief summary: The purpose of this study is to evaluate the safety and tolerability of single and multiple doses of ISIS 353512, to evaluate the blood concentration and rate elimination of ISIS 353512 from the blood, and to evaluate the effectiveness of ISIS 353512 in lowering a protein in the blood associated with inflammation.

Detailed description: This will be a Phase 1, double blind, placebo-controlled, dose-escalation study conducted at a single center to 1)evaluate the safety and tolerability of single and multiple doses of ISIS 353512 administered intravenously and subcutaneously, 2)evaluate the pharmacokinetic profile of single and multiple doses of ISIS 353512 administered intravenously and subcutaneously, and 3)evaluate the pharmacodynamics of ISIS 353512 in lowering constitutive levels of c-reactive proteins in healthy volunteers.

Exclusion Criteria:

* Pregnant women, nursing mothers or women of childbearing potential

* Clinically significant abnormalities on laboratory examination, other than hsCRP
* Clinically significant abnormalities in coagulation parameters
* Positive test for HIV, TB (PPD test) or hepatitis B or C at Screening
* History of latent or active tuberculosis or exposure to endemic areas within 8 weeks prior to PPD test at Screening
* History of positive PPD test or positive PPD test result (≥ 5 mm) indicating possible tuberculosis infection
* Fasting triglycerides \> 400 mg/dL at Screening
* Malignancy (with the exception of basal or squamous cell carcinoma of the skin if adequately treated and no recurrence for \> 1 year)
* Evidence of ongoing chronic inflammatory condition or infection
* Any other concurrent condition which, in the opinion of the Investigator, would preclude participation in this study or interfere with compliance
* Regular use of alcohol within 6 months prior to Screening (\> 14 units of alcohol per week; 1 unit = 150 mL of wine, 360 mL of beer, or 45 mL of 40% alcohol)

* Smoking \> 10 cigarettes per day
* Use of an investigational drug or participation in an investigational study involving a small molecule with 30 days prior to dosing or participation in an investigational study involving biologic compounds within 90 days prior to dosing
* Regularly taking OTC medications and/or vitamin supplements that may alter CRP, e.g., NSAIDs, aspirin, vitamin E, fish oil, within 14 days prior to Screening
* Receiving prescription medications, including hormone replacement therapy, statins, TNF-α inhibitors, or other anti-inflammatory or immunosuppressive drugs within 30 days prior to Screening
* Immunization with a live attenuated vaccine one month prior to dosing or planned vaccination during the course of the study
* Blood donation of 50 to 499 mL within 30 days of Screening or of \> 499 mL within 60 days of Screening
