APS & Related Diseases Research and Clinical Trials
At this time, the APS Foundation of America does not fund research, however we do plan on doing so in the near future. Please see our donate page for details
The following organizations are currently doing research on APS or related diseases. We encourage anyone who qualifies to participate in these clinical studies. By doing so, you could potentially help APS patients in the future!
Clinical Study 5806: Genetics of antiphospholipid antibody syndrome (APS)
Now Recruiting: We know very little about what causes antiphospholipid antibody syndrome (APS). Sometimes several family members have APS. Other times, one person has APS and other relatives have a different autoimmune disease like lupus or diabetes. Because APS sometimes runs in families, we think that certain genes may cause APS. The purpose of this study is to find the genes that cause
Participants will be recruited for this study using brief diagnostic inclusion criteria for antiphospholipid antibody syndrome. This includes: (1) Persistent presence of an antiphospholipid antibody (aPL), defined as: (a) Elevated anticardiolipin antibody level in the blood, present in medium or high titer, on 2 or more occasions, at least 6 weeks apart; and/or (b) Lupus anticoagulant present in plasma, on 2 or more occasions at least 6 week apart and (2) Presence of clinical symptoms seen in patients with APS.

Genetic Risk Factors Associated With Antiphospholipid Antibody Syndrome (APS)
Antiphospholipid antibody syndrome (APS) is characterized by the presence of antiphospholipid antibodies, which are proteins in the blood that interfere with the body's ability to perform normal blood clotting. Clinical problems associated with antiphospholipid antibodies include an increased risk for the formation of blood clots in the lungs or deep veins of the legs, stroke, heart attack, and recurrent miscarriages. It is possible that some people with APS have a genetic predisposition for developing the syndrome. This study will use a genetic strategy to identify potential inherited risk factors for the development of APS by recruiting people with APS who have family members also affected by the syndrome or by another autoimmune disorder, such as lupus or rheumatoid arthritis.
Nonmyeloablative Allo Stem Cell Transplant for Severe Autoimmune Diseases
Autoimmune diseases present a special challenge to clinicians and the aim of this protocol is to serve as a last-line effort for patients with unmanageable disease. The primary purpose of this study is to assess feasibility in terms of toxicity and engraftment of a less toxic, nonablative conditioning regimen of Campath-1H, moderate dose fludarabine, and cyclophosphamide for patients with severe autoimmune diseases.

Eculizumab to Enable Renal Transplantation in Patients With History of Catastrophic Antiphospholipid Antibody Syndrome
Catastrophic Antiphospholipid Antibody Syndrome (CAPS) is a rare condition in which life-threatening blood clots form in multiple organs simultaneously and can lead to multi-organ system failure and death. The causes of CAPS are not entirely understood, but CAPS episodes are often triggered by stressful events such as infections, surgery, or trauma. For patients who survive an episode of CAPS, permanent kidney failure is not uncommon because the kidneys are the organ system most frequently affected in CAPS. Kidney transplantation is the treatment of choice for end-stage kidney disease, but patients with a history of CAPS are exceptionally high-risk kidney transplant recipients because the chance that surgery itself could trigger a life-threatening or transplant-threatening episode of CAPS is significant. As a result, patients with CAPS are not generally considered candidates for transplantation. Despite this, these patients have a severely decreased life-expectancy on dialysis and their long-term survival and quality of life would be greatly increased by a successful kidney transplant. In this trial, a drug called eculizumab will be tested for its ability to prevent CAPS after kidney transplantation in patients with a prior history of CAPS. Eculizumab is an inhibitor of the complement system, which is believed to be important in generating the inflammatory environment that leads to diffuse clotting of blood vessels in CAPS. The investigators hypothesize that by blocking the complement cascade using eculizumab, in conjunction with blocking the coagulation system, that kidney transplantation can be safely and successfully performed in patients with a history of CAPS.
Predictors of Pregnancy Outcome in Systemic Lupus Erythematosus (SLE) and Antiphospholipid Syndrome (APS) (PROMISSE)
The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregnancy outcome in patients with systemic lupus erythematosus (SLE) and anti-phospholipid syndrome (APS), and/or 2) to determine whether elevated levels of circulating antiangiogenic factors predict pregnancy complications in patients with aPL antibodies and/or SLE.
Hematopoietic Stem Cell Transplantation in Patients With Antiphospholipid Syndrome
Antiphospholipid syndrome is disease believed to be due to immune cells, cells which normally protect the body, but are now producing the protein which leads to abnormal clotting in the body. This study is designed to examine whether treating patients with high dose cyclophosphamide together with CAMPATH (drugs which reduce the function of the immune system), followed by return of the previously collected stem cells will result in improvement in the disease. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the intense chemotherapy is to destroy the cells in the immune system which may be causing the disease. The purpose of the stem cell infusion is to produce a normal immune system that will no longer attack the body. The study purpose is to examine whether this treatment will result in improvement in the disease. The drugs used in this study treatment are drugs for commonly used for immune suppression.
Pharmacokinetics of Low Molecular Weight and Unfractionated Heparin in Pregnancy
To determine, through pharmacokinetic parameters, the ideal dosing protocol for dalteparin (a low molecular weight heparin) and unfractionated heparin for women desiring pregnancy who have evidence of an acquired (specifically, antiphospholipid syndrome) or inherited thrombophilia.
Effectiveness of Bridging Anticoagulation for Surgery (The BRIDGE Study)
Blood thinners, such as warfarin, prevent blood clots from forming, thereby reducing the risk of a stroke or heart attack. When people undergo surgery or certain procedures, they must stop using warfarin to prevent too much bleeding during and after the surgery or procedure. Some doctors prescribe a different blood thinner, one that works more quickly and wears off more quickly, to bridge the gap between starting and stopping warfarin. However, this short-term treatment is expensive, may increase the risk of bleeding, and has not been proven effective. This study will determine whether a bridging blood thinner called dalteparin is helpful or harmful for people with atrial fibrillation who stop taking warfarin in preparation for surgery or a procedure.

Throbmotic Storm (CAPS) Study
Most patients with venous thromboembolism present with either deep vein thrombosis, most commonly affecting the legs, or pulmonary embolism. A subset of these patients may present with a rapidly progressive clinical course that is characterized by multiple, life-threatening thromboembolic events, frequently developing in unusual locations (e.g., dural sinus vein thrombosis or intra-abdominal thrombosis). These patients may be difficult to treat, potentially unresponsive to standard therapeutic protocols, and also may manifest with complex coagulopathies, including disseminated intravascular thrombosis. This phenotype, which has been referred to as 'thrombotic storm', may be associated with an underlying primary hypercoagulable state. It has also been described in patients with antiphospholipid syndrome (referred to as 'catastrophic antiphospholipid syndrome', or catastrophic APS), malignancy, infections, and during pregnancy. Thrombotic storm has also been described in pediatric patients.
The primary purpose of this study is to characterize patients with 'thrombotic storm' syndromes (including patients with the catastrophic APS), track their subsequent clinical course over time, obtain detailed family history information to identify any potentially inherited patterns for thrombotic complications or autoimmune disorders, and identify individual genetic factors that contribute to this rare, but extremely serious manifestation. Participants in the study are asked to provide family history information, answer questions about medical and environmental history, provide demographic information, and provide a blood sample. Participants are also asked to update this information yearly. Travel to the researcher is not required and there is no cost to the participant. In addition, participants are not paid to participate.
Ultimately, we hope that data from this research will lead to improvements in prediction, diagnoses, prevention, and treatment of this serious disorder.

Pharmacogenetics of Warfarin in Puerto Rican Patients Using a Physiogenomics Approach
Warfarin (Coumadin) is a prescribed "blood thinner" medication used to make the blood less thick in people with high risk of forming blood clots. Despite the various methods to monitor this drug, life-threatening bleeding is a common undesired effect and might result in patient death. Patients starting warfarin therapy may require several weeks or even months to reach the appropriate blood level of warfarin. This blind practice could place the patient at high risk. There are several demographic and clinical factors that significantly influence how much warfarin the patient needs to attain the desired response. Genes, which control hereditary traits, are also important. Now, the investigators know that by using the information encoded in patient's genes the investigators are able to individualize the therapy. Two genes are considered to be involved in warfarin response (CYP2C9 and VKORC1). This study proposes to ascertain what CYP2C9 and VKORC1 variants are present in warfarin-treated Puerto Rican patients. To this purpose, a novel physiogenomic array comprising 384 variants in 222 genes of cardio-metabolic relevance will be used so the investigators are able to determine the structure of the Puerto Rican population in terms of ancestral contributions and how the admixture may impact the prevalence of CYP2C9 and VKORC1 variants. Secondly, the investigators will assess the association of these variants to clinical responses in order to develop a better method of dose estimation. The expected result is the improvement of warfarin therapy in Puerto Ricans. The proposed study will fill a gap in the knowledge of warfarin pharmacogenetics, providing new information on the prevalence of CYP2C9 (metabolism) and VKORC1 (sensitivity) polymorphisms in Puerto Ricans as well as their role in the warfarin response variability observed in this admixed population.
A Pilot Study of Rituximab (Rituxan)for the Anticoagulation Resistant Manifestations of Antiphospholipid Syndrome (RITAPS)
RITuximab AntiphosPholipid Syndrome (RITAPS) Study is designed to evaluate whether a medication called rituximab would reduce the signs and symptoms of antiphospholipid antibody (aPL) -related certain clinical problems.
