Comparing Treatments for Multiple Myeloma Clinical Trials Data presented on Clinical Trials Search is not meant to be a substitute for qualified medical advice, visits or professional assistance with a genuine dr.. We are not doctors. Always consult your mD about Comparing Treatments for Multiple Myeloma conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Comparing Treatments for Multiple Myeloma Clinical research trials and Comparing Treatments for Multiple Myeloma medical trials take place in many of places throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectiveness of new does drugs. The purpose of the studies / projects is to solve specific human healthcare questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to find cures for all varieties of conditions, like Comparing Treatments for Multiple Myeloma. Comparing Treatments for Multiple Myeloma Clinical Trials and other clinical trials allow for volunteers to have health treatment options before they are available to the masses. Many times the human subjects acquire professional assistance for free of charge, and sometimes they are compensated for their time. Occasionally there is a cost for a Comparing Treatments for Multiple Myeloma clinical trial. Test subjects typically obtain the finest healthcare available for their Comparing Treatments for Multiple Myeloma condition. Dangers are a reality, nevertheless, and might include additional or frequent doctor trips, medical dangers (possibly life-jeopardising), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials patients.

Comparing Treatments for Multiple Myeloma
For Condition: Multiple Myeloma
Status: Completed
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: Some drugs have the ability to push stem cells (the cells responsible for producing new cell types) out of the bone marrow and into the blood stream. The steps involved in this process are still poorly understood. However, a better understanding of this process could lead to improved results in transplantation, cancer treatment, and contribute to the development of new genetic therapies for a wide variety of disorders. In this study researchers plan to compare two different treatments, both that mobilize (push) stem cells out of the bone marrow into the blood stream. In addition, researchers will attempt to determine which is the most efficient at mobilizing blood cells of patients with multiple myeloma. Information and knowledge gained from this study will help to design future transplantation and genetic therapy research studies.
Details: Some drugs, such as hematopoietic cytokines, result in mobilization of primitive stem cells out of the bone marrow space and into the blood, but the mechanisms of this process are still poorly understood. A better understanding of this process could greatly improve clinical results in transplantation, cancer treatment, and potentially genetic therapy of a wide variety of disorders. In this protocol, we will study two different mobilization treatments and compare how efficient they are at increasing the number of primitive cells in the blood in patients with multiple myeloma. These cells will be collected by apheresis, and used for autologous transplantation following high dose chemotherapy. This aggressive approach to treatment in multiple myeloma has been shown to improve remission rates and survival without active disease. The use of a larger number of blood stem cells may decrease the toxicity associated with the procedure. In the research laboratory, we will study a number of characteristics of the primitive cells in the blood and the bone marrow after treatment with the mobilizing drugs. These studies will help us to design future transplantation and genetic therapy protocols.
Eligibility:
Study Type: Interventional, Treatment, Safety/Efficacy
Minimum Age/Maximum Age: /
Genders: Both
Protocol Entry Criteria: INCLUSION CRITERIA Age 70 or younger at time of pretransplant evaluation. An established diagnosis of multiple myeloma. ECOG performance status of 0 or 1 and a life-expectancy of greater than 6 months. Marrow cellularity greater than 20 percent, with less than or equal to 30 percent plasma cells within one month of study entry. Platelet count greater than 100,000/ul, ANC greater than 1200/ul. Demonstration of a partial or complete response to initial or salvage therapy (a minimum of a 50 percent reduction in the detectable serum paraprotein or at least a 90 percent reduction in the detectable urine monoclonal light chains, stable for at least four weeks prior to entry into study). A cumulative total of less than or equal to 6 cycles of regimens containing alkylating agents. Bilirubin less than 2.0, transaminases less than 2x upper limit of normal, serum creatinine less than 3.0. Ability and willingness to give informed consent. EXCLUSION CRITERIA Prior bone marrow or PBSC transplant. HIV positivity. Extensive marrow fibrosis, non-aspirable marrow, myelodysplastic changes or greater than 30 percent marrow plasma cells. Prior treatment with greater than 6 cycles of chemotherapy regimens containing alkylating agents such as melphalan, cyclophosphamide or BCNU. History of another malignancy within 5 years of protocol entry, with the exception of localized carcinomas cured by surgical resection such as basal cell carcinoma, stage I breast or bladder cancer, or in situ carcinoma of the cervix. Significant nonmalignant disease including uncontrolled hypertension, unstable angina, congestive heart failure, poorly controlled diabetes, coronary angioplasty within 6 months, myocardial infarction within 6 months, uncontrolled arrhythmias, or any other medical condition felt by the principal investigator to unduly increase the risk of autologous transplantation. Significant allergy history: these criteria will be assessed via the Allergy History CRF Screening Form. Patients with any of the following concurrent conditions are not eligible: No history of positive allergy tests to insect venoms (either skin or RAST). No history of seasonal or recurrent asthma within the preceding 10 years. No asthmatic symptoms (e.g. wheezing) related to a current respiratory tract infection. No anaphylactic/anaphylactoid-type event manifested by disseminated urticaria, laryngeal edema, and/or bronchospasm (or for example: food, insect bites, etc.) Patients with drug allergies, manifest solely by rash, and/or urticaria are not excluded. No history of angioedema or recurrent urticaria (an isolated episode of urticaria is not a contraindication). No active infection (including those with current symptoms of bronchoconstriction), or fever greater than or equal to 38.2 degrees Celsius. No known allergy to E. coli-derived products. No concurrent use of beta adrenergic blocking agents. No concurrent use of other investigative agents. No pregnancy or breast-feeding. Men and women of child-bearing potential, admitted to the trial are to be advised to take adequate measures to prevent conception. Patients maintained on interferon, chemotherapy or hematopoietic growth factors must have these treatments discontinued for at least four weeks prior to entry into this study.
