Active clinical trials for "Recurrence"

Recurrent aphthous stomatitis (RAS) is a common recurrent oral disorder with no curative treatment available to date. The challenge remains in patients that do develop drug resistance and/or secondary infection, although topical corticosteroids and antimicrobials are the first therapeutic choice. The aim of the study was to evaluate the efficacy and safety of an herbal extract of Yunnan Baiyao formulated in toothpaste as an alternative therapy for minor RAS. Yunnan Baiyao is a well-known traditional Chinese medicine, formulated in a powder or capsule form. It was initially and widely used in wounds for its anti-hemorrhagic hemostatic function, and further in gastrointestinal bleeding. Yunnan Baiyao powder has been generally applied on RAS among Chinese population. In this study, a randomized, double-blind, placebo-controlled clinical trial (from March 2010 to March 2011) was conducted on a cohort of 227 minor RAS patients. The toothpaste containing Yunnan Baiyao was used twice daily as part of the patient's routine oral hygiene for 5 days. An assessment of ulcerative size and pain was recorded on Day 0 (baseline), Day 3 and Day 5. Any noted adverse reactions were recorded.

The purpose of this phase I study is to determine the highest dose of carboplatin and gemcitabine (gemcitabine hydrochloride) that can be given safely to subjects with gynecologic cancer, in combination with stereotactic body radiation therapy (SBRT). This dose is called the maximum tolerated dose (MTD). To determine the MTD, patients will receive different amounts of carboplatin and gemcitabine.

This phase II trial studies how well alisertib works in treating patients with sarcoma that has spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) or has spread to other places in the body (metastatic). Alisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Recurrent miscarriage (RM) is traditionally defined as three or more consecutive miscarriages occurring before 20 weeks post-menstruation. It is one of the most common clinical problems in reproduction, yet a definite cause can be established in only 50 percent of cases (ACOG practice bulletin, 2002). Many etiological factors have been proposed but none of them has been fully substantiated. RM has been directly associated with maternal thrombophilic disorders, parental chromosomal anomalies, and structural uterine anomalies and indirectly with maternal immune dysfunction and endocrine abnormalities. The association between pregnancy loss and antiphospholipid antibodies (aPL) was first noticed in the latter third of the last century. The antiphospholipid syndrome (APS) is characterized by the presence of antiphospholipid antibodies (APLA), associated with venous and/or arterial thrombosis, and/or pregnancy loss. The adverse pregnancy outcomes associated with the presence of APLAs include: recurrent fetal loss, intrauterine growth restriction (IUGR), and severe pre-eclampsia especially of early onset. Testing the effect of Heparin in treatment of cases with RA but negative for APA has bee done in few animal and clinical studies. Animal studies showed that the subset of cases with disorders suspicious for APS but who had negative test results for LAC and aCL is carrying antibodies pathogenic to murine pregnancy. Testing other immunoglobulin G may provide additional means to identify cases with an yet uncharacterized immune condition. Moreover, the clinical relevance of low levels of APLA in these women remains unproved. Randomized prospective study was done to assess the efficacy of early thromboprophylaxis of Low molecular weight heparin (LMWH) (Enoxaparin sodium 20 mg, once daily subcutaneously) in women with a history of recurrent miscarriages without identifiable causes versus no treatment. The results showed that, there is a significant reduction in the incidence of both early and late miscarriages (8.8% vs 4.1%) (2.3% versus 1.1%) with or without treatment, respectively. Cochrane Database systemic review (2005) shows randomized comparative studies for treating recurrent miscarriage in women without antiphospholipid syndrome. The first group treated by low dose aspirin alone and the second group treated by low dose aspirin + LMWH. The result of these studies shows that no significant differences between the two groups and identify the need of large randomized controlled trial to solve this problem. The above evidence suggests the probability of presence of untested LAC and aCL or very low levels of APLA by commonly used methods in women with recurrent miscarriage. These antibodies may explain recurrent miscarriage in cases with negative antiphospholipid antibodies. It remains to test the efficacy of heparin (proven effective treatment in those with positive antibodies) in the patients with negative antibodies. Finding a solution to this frustrating problem may open the way for an unsolved problem. The proposed study is an open labeled randomized controlled trial (RCT) To evaluate the effect of LMWH versus no heparin in treatment of recurrent miscarriage that is negative for antiphospholipid antibodies testing.

The overall objective of this protocol is to improve the cure rate of relapsed precursor B-cell acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma. This phase II trial is studying risk-directed therapy for B-lymphoblastic leukemia or lymphoma in first relapse. Standard risk (SR) and high risk (HR) participants will receive different therapy. Treatment will consist of chemotherapy for SR participants, and chemotherapy followed by hematopoietic stem cell transplant (HSCT) for HR in first relapse. Induction therapy consists of three blocks of chemotherapy. The first block is a novel immunotherapy regimen that includes chemotherapy, rituximab and infusion of haploidentical natural killer (NK) cells. SR participants will continue to receive chemotherapy for a total duration of approximately 2 years. HR participants will be candidates for HSCT and will proceed to transplant once a suitable donor is found and their minimal residual disease (MRD) is negative.

This Phase 2 study is designed to characterize the objective response rate (defined as complete response (CR) and partial response (PR)) of Etirinotecan pegol administered to subjects with metastatic and recurrent NSCLC after failure of 2nd line therapy. Up to 37 eligible subjects will receive the investigational drug q3 weeks until they are no longer benefiting.

This phase I/II trial studies the side effects and the best dose of brentuximab vedotin when given together with gemcitabine hydrochloride and to see how well they work in treating younger patients with Hodgkin lymphoma that has returned or does not respond to treatment. Monoclonal antibodies, such as brentuximab vedotin, may find cancer cells and help kill them. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving brentuximab vedotin together with gemcitabine hydrochloride may kill more cancer cells.

This trial will be the first study of axitinib in children and adolescents. The primary objective of this Phase 1 trial is to determine a maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of axitinib in pediatric patients with refractory solid tumors. Additional objectives include measurement of pharmacokinetic and pharmacodynamic parameters, description of the toxicity profile of this agent in children and adolescents, and assessment of response within the confines of a Phase 1 trial. A standard rolling 6 design will be used for dose escalation. Further development of axitinib will focus on development of a joint cooperative group (COG/ECOG) Phase 2 study of axitinib in pediatric, adolescent and young adult translocation renal cell carcinoma.

The present survey was conducted to evaluate the efficacy and safety of GB-0998(immunoglobulin) in the treatment of unexplained recurrent miscarriage in comparison to placebo using a multicenter, double-blind, intergroup comparison method.

This phase I trial studies the side effects and best dose of alisertib and romidepsin in treating patients with B-cell or T-cell lymphomas that have returned after a period of improvement (relapsed) or have not responded to treatment (refractory). Alisertib and romidepsin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
