Active clinical trials for "Polycythemia"

This phase I trial is studying the side effects and best dose of vorinostat when given together with cytarabine and etoposide in treating patients with relapsed or refractory acute leukemia or myelodysplastic syndromes or myeloproliferative disorders. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cytarabine and etoposide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving vorinostat together with cytarabine and etoposide may kill more cancer cells.

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of imatinib mesylate in treating patients who have advanced cancer and liver dysfunction

The purpose of the RELIEF study is to compare symptoms in polycythemia vera (PV) subjects treated with ruxolitinib versus subjects treated with hydroxyurea (HU) as measured by the percent of subjects who achieve a clinically meaningful symptom improvement (ie, total symptom score reduction of ≥ 50% reduction) at Week 16 compared to Baseline. The study is also designed to demonstrate that these responses are durable with continued treatment.

Chronic mountain sickness is characterized by excessive red blood cell production which causes sludging of the vascular system. This high viscosity blood causes heart failure, cognitive dysfunction, and strokes. The investigators hypothesize that cobalt which has been previously been shown to be an environmental pollutant worsens the overproduction of red blood cells. The investigators plan to conduct a 6 week trial in which acetazolamide (already shown to improve chronic mountain sickness) and N-acetylcysteine (a drug that removes cobalt from the blood) are evaluated in their potential to improve chronic mountain sickness.

This study will evaluate the transfusion independence response rate in transfusion-dependent adults with myelofibrosis after treatment with momelotinib (MMB).

The purpose of this study is to determine a dose of LY2784544 that may be safely administered to participants with myeloproliferative neoplasms.

Hypogonadism (low testosterone) is becoming an increasingly recognized problem that affects numerous men in the United States. Symptoms may be always feeling tired, lower sex drive, and loss of muscle mass. Treatment typically involves testosterone in either injections or a topical gel form. However, administration of testosterone is not without side effects of its own. Testosterone supplementation therapy is known to cause a variety of side effects including high blood pressure and high lipids (fats) and an increased proportion of red blood cells. Side effects of increased red blood cells can include an increased risk of developing a blood clot. The increase in the red blood cells is related to dihydrotestosterone (DHT - a male sex hormone) activity. It is normal for the testosterone to become DHT. DHT has various effects on the body including growth of the prostate gland, baldness, and others and DHT levels have been linked to elevated red blood cell counts in men on testosterone. Finasteride is an FDA approved medication used in the treatment of benign prostatic hypertrophy (BPH) in men with enlarged prostate to improve symptoms and to reduce the risk of the need for surgery. Finasteride may prevent elevations in or reduce elevated red blood cell levels in men on testosterone.

The main purpose of this investigational research study is to determine how safe and tolerable the study drug siltuximab is in patients with myelofibrosis (MF). This medication has been approved by the FDA for another condition (multicentric castleman's disease (MCD), but not for myelofibrosis (MF). In MCD, siltuximab resulted in improvement in symptoms and anemia. While MCD and MF are different diseases, they share some common features including a protein call interleukin-6 (IL-6) that may be important in causing symptoms of MCD and MF.

The purpose of this study is to investigate the safety, pharmacokinetics (PK) and preliminary efficacy of both the combination of MBG453 and NIS793 with or without decitabine or spartalizumab as well as single agent MBG453 and/or NIS793 single agent in myelofibrosis (MF) subjects post treatment with a Janus Kinase (JAK) inhibitor. In this study, combination therapies with novel agents including immune therapy will focus on determining the promising combinations that provide acceptable safety and efficacy independent of JAK inhibitors. Immune therapy combinations, such as MBG453 in combination with NIS793, might offer the potential to target MF across genetic heterogeneity. The primary objective of this study is to characterize the safety, tolerability and recomended dose for each treatment combination (MBG453 + NIS793, MBG453 + NIS793 + decitabine, and MBG453 + NIS793 + spartalizumab)
