Patients who are randomized to this group will take a low-dose aspirin 81mg pill once per day (standard-of-care) for at least 6 months along with cytoreductive therapy, if applicable. Patients will then be treated and followed up as per standard of care at the discretion of his or her treating physician after the completion of the study.

Patients who are randomized to this group will receive apixaban 2.5mg twice daily for at least 6 months along with standard intervention, cytoreductive therapy, if applicable.

Myeloproliferative neoplasms (MPNs) are blood disorders that occur when the body makes too many white or red blood cells, or platelets. This overproduction of blood cells in the bone marrow can create problems for blood flow and lead to various symptoms. One of the major problems is the formation of blood clots. These may form in the veins of a patient's legs or arms where they cause leg or arm pain, swelling or difficulty walking. These clots may travel to the lung and then cause chest pain, shortness of breath and sometimes death. Blood clots can also lead to poor or no blood flow to one's heart, brain, or other organs, causing damages that cannot be easily or ever repaired, such as stroke or heart attack.

Patients diagnosed with certain types of MPN are associated with a higher risk of developing blood clots and related complications. For this reason, MPN patients are usually treated with low-dose aspirin, a common drug used for blood clot prevention, on long-term basis to prevent the formation of blood clots and other complications. However, recent studies also show that the risk of blood clots remains elevated in MPN patients treated with aspirin, and there may not be improvement or reduction in fatal or other events that are associated with blood clots. In addition, since this medical condition is rare, so there's a lack of studies done with high quality results to help physicians decide the best treatment plan for these patients.

The study drug, apixaban, is a new type of orally-taken blood thinner that has been shown to be effective and safe for prevention and treatment of blood clots in various patient populations. The investigators will evaluate whether apixaban is safer and/or better at preventing blood clots and other complications in MPN patients compared to aspirin.

Assessing Feasibility of Thromboprophylaxis With Apixaban in JAK2-positive Myeloproliferative Neoplasm Patients

A Phase 2 Pilot Randomized Controlled Trial Assessing Feasibility of Thromboprophylaxis With Apixaban in JAK2-positive Myeloproliferative Neoplasm Patients

Feasibility of recruitment efforts will be determined by the proportion of patients contacted for screening versus those who are consented

Feasibility of enrollment will be determined by the proportion of patients consented vs those were enrolled and randomized

This will be defined as the proportion of patients who started study intervention versus those who completed each of the study follow-up visits.

This will be defined as the total number of arterial and venous thrombotic events developed relative to the total number of patients who received study treatment

This will be defined as the total number of adjudicated major bleeding events relative to the total number of patients who received study treatment

This will be defined as the total number of adjudicated non-major clinically relevant bleeding events relative to the total number of patients who received study treatment

This will be defined as the total number of adjudicated deaths relative to the total number of patients who received study treatment

Subjects will take 81mg tablets of aspirin daily for 14 days prior to surgery for removal of fallopian tubes.

Subjects will take aspirin daily for 14 days leading up to surgery to determine whether it impacts inflammation of fallopian tubes.

This study will evaluate the impact of low dose aspirin on normal fallopian tube fimbriae in women who have surgery to have their fallopian tubes removed. Participants will take a low dose of aspirin for 2 weeks before their surgery. A portion of the removed fallopian tubes will also be collected for future research and routine pathology purposes.

Subjects in this study will receive low dose aspirin for 14 days before undergoing surgery to remove fallopian tubes removed to determine whether aspirin decreases inflammation in the fallopian tube. Subjects will also submit blood samples at their initial visit with their oncologist, at the time of surgery and at the pre-operative visit to measure inflammation markers and blood counts. A portion of the subject's fallopian tube will be collected for future research studies.

Short Term Aspirin on the Biologic and Immunologic Changes of the Fallopian Tube

A Surgical Window Pilot Investigation of Short Term Aspirin on the Biologic and Immunologic Changes of the Fallopian Tube

Immuno-cellular assays and percentages of specific immune cells will be compared to control tissue samples.

Ciliate cells from specimens will be isolated and the number of colony forming units will be compared to control samples.

Normal fallopian tube fibria will be compared to ovarian cancer specimens to identify novel biomarkers for diagnosis, targets for prevention and better treatment strategies.

This is a phase II placebo-controlled intervention trial assessing aspirin (ASA) as a UV protectant in patients at risk for melanoma.

While melanoma risk is largely genetically determined, exposure to ultraviolet (UV) radiation in sunlight is the major environmental risk factor. Although sunscreen use can reduce melanoma risk 2-fold, its efficacy has been questioned, and most patients do not apply sunscreens properly.

This study will evaluate the downstream effects of aspirin (ASA) in human blood and skin moles (nevi) following oral ingestion. We will determine if chronic ingestion of ASA can modulate UV-sensitivity of the skin, UV-induced damage in nevi, and PGE2 levels in blood and nevi.

A Phase II Placebo-controlled Intervention Trial of Oral Aspirin (ASA) as a UV Protectant in Vivo

Baseline minimal erythemal dose (MED) measurements will will be compared to MED results at day 60. We will use the conventional definition of MED as the lowest UV dose resulting in erythema that completely fills the 8-mm irradiated site (homogeneous erythema).

Baseline PGE2 levels in plasma specimens will be compared to PGE2 levels at day 60.

Baseline PGE2 levels in tissue specimens will be compared to PGE2 levels at day 60.

Baseline 2-HG levels in plasma specimens will be compared to 2-HG levels at day 60.

Baseline 8-OG levels in plasma specimens will be compared to 8-OG levels at day 60.

Baseline 2-HG levels in tissue specimens will be compared to 2-HG levels at day 60.

Baseline 8-OG levels in tissue specimens will be compared to 8-OG levels at day 60.
