Inclusion Criteria

• HIV-1 infection.

• No change in ART regimen within the 12 weeks prior to study entry (except as noted below).

NOTE: Modifications of ART dosing during within the 12 weeks prior to entry are permitted. In addition, the change in formulation (eg, from standard formulation to fixed dose combination or single tablet regimen) or dosing (eg, from once a day to twice a day) is allowed within 12 weeks prior to entry. Within-class single drug substitution (eg, switch from nevirapine to efavirenz or from atazanavir to darunavir), are not allowed within 12 weeks prior to entry. No other changes in ART in the 12 weeks prior to entry are permitted.

• Screening HIV-1 RNA must be 100,000/mm^3
• Prothrombin time (PT) /= 70 within 45 days prior to study entry
• Ability and willingness of subject or legal guardian/representative to provide written informed consent.
• Willingness to refrain from the use of aspirin or any aspirin-related product (other than the study drug), including NSAIDs, from time of screening visit through the end of the 16 week trial.

NOTE: Acetaminophen-based products may be used before and during the trial when analgesics are required.

• Completion of the pre-entry FMD assessment NOTE: The FMD must be performed at the site and confirmed as acceptable by the University of Wisconsin Atherosclerosis Imaging Research Program (UW AIRP) core lab prior to study entry.
• Confirmation of the availability of the stored pre-entry fasting specimens (plasma and serum); the site must confirm that these specimens have been entered into the Laboratory Data Management System (LDMS).

Exclusion Criteria

• Current malignancy (except non-melanoma cancer of the skin not requiring systemic chemotherapy or radiation therapy).

NOTE: Carcinoma in situ of the cervix or anus is not considered exclusionary.

• Prior history of malignancy if the subject is not disease free for 24 or more weeks prior to study entry.
• Current use or indication for use of non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin that cannot be interrupted for clinical reasons. Examples of clinical reasons include, but are not limited to, known and documented cardiovascular disease (history of MI, coronary artery bypass graft surgery, percutaneous coronary intervention, stroke, transient ischemic attack, peripheral arterial disease with ABI 1000 mg of marine oils daily).
• Known cirrhosis
• Known chronic active hepatitis B NOTE: Active hepatitis B is defined as hepatitis B surface antigen positive and hepatitis B DNA positive within 24 weeks prior to study entry; subjects with hepatitis B virus (HBV) DNA BLQ for greater than 24 weeks prior to study entry are eligible.
• Known chronic active hepatitis C NOTE: Active hepatitis C is defined as a detectable plasma HCV RNA level within 24 weeks prior to study entry; subjects with HCV RNA BLQ for greater than 24 weeks prior to study entry are eligible.
• Known inflammatory conditions, such as, but not limited to, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), sarcoidosis, inflammatory bowel disease (IBD), chronic pancreatitis, autoimmune hepatitis, Adult Stills disease, Rheumatic heart disease, bursitis.
• Breastfeeding or pregnant
• Previous intolerance or allergy to aspirin or any aspirin products.
• Frequent use of aspirin or aspirin products (NSAIDs), defined as an average of 2 or more times per week in the last 12 weeks prior to study entry.
• Immunosuppressant use, such as, but not limited to, systemic or potentially systemic glucocorticoids (including injected, ie, intra-articular, nasal or inhaled steroids), azathioprine, tacrolimus, mycophenolate, sirolimus, rapamycin, methotrexate, or cyclosporine wit
