Emerging safety concerns thrombosis, cardiovascular events, memo Thrombophlebitis progression, Krampfadern in den Beinen Video reduced survival derived from clinical trials in several cancer and non-cancer populations prompted CMS to review its coverage of erythropoiesis stimulating agents ESAs.
We reviewed a large volume of scientific literature, Thrombophlebitis Betrieb y, including basic science http: In memo Thrombophlebitis so we proposed conditions of coverage based on expression of erythropoietin receptors. The scientific understanding of this mechanism is a subject of continuing debate among stakeholders, continues to evolve, and can only be resolved through additional studies.
We also reviewed a memo Thrombophlebitis volume memo Thrombophlebitis comments on the use of ESAs in myelodysplastic syndrome MDSa pre-malignant syndrome that transforms into acute myeloid leukemia AML in many patients.
Though we continue to be interested in these specific issues, this final decision does not differentiate ESA coverage by memo Thrombophlebitis Betrieb y erythropoietin receptor status of the underlying disease, and we have narrowed the scope of this final decision to make no national memo Thrombophlebitis determination NCD at this time on the use of ESAs in MDS.
CMS has determined that there is sufficient evidence to conclude that erythropoiesis stimulating Varizen in Maikop ESA treatment is not reasonable and necessary for beneficiaries with certain clinical conditions, either because of Thrombophlebitis Betrieb y deleterious effect of the ESA memo Thrombophlebitis their underlying disease or because the underlying disease increases their risk of adverse effects related to ESA use.
We have also determined that ESA treatment Thrombophlebitis Betrieb y the anemia secondary to myelosuppressive anticancer chemotherapy in solid tumors, multiple myeloma, lymphoma and lymphocytic leukemia is only Thrombophlebitis Betrieb y and necessary under the following specified conditions: Local Medicare contractors may continue to make reasonable and necessary determinations on all uses of ESAs that are not determined by NCD.
In this section in our proposed decision memorandum, we described the technological developments that gave rise to the use of genetically engineered memo Thrombophlebitis erythropoietin and related ESAs see appendix A.
We then described the anemias for which ESAs are prescribed in oncologic conditions, Thrombophlebitis Betrieb y, with an emphasis on solid tumors that constituted the majority of tumors in the studies upon which FDA approval was based. We refer memo Thrombophlebitis reader to Appendix A for a detailed discussion of the biochemical background of ESAs and their current memo Thrombophlebitis. We will summarize these points here.
Erythropoietin is a glycoprotein produced primarily memo Thrombophlebitis the kidney and to a lesser extent in the liver. In the classic hormone pathway, erythropoietin regulates erythrocyte production by stimulating red cell production in the bone marrow.
Suppression of erythropoietin production or suppression of the bone marrow response to erythropoietin has resulted in anemias in several disease processes to include renal disease, Thrombophlebitis Betrieb y, cancer treatment, other chronic diseases and use of certain drugs. To combat these anemias, several forms of recombinant human Thrombophlebitis Betrieb y have been developed. The two currently available in the US are epoetin and darbepoetin alpha. Recombinant erythropoietin was initially used as a replacement for missing hormone in select memo Thrombophlebitis with anemia of memo Thrombophlebitis renal disease.
Use of ESAs has been extended to a variety memo Thrombophlebitis anemic conditions including the anemia of chronic renal disease not yet on dialysis memo Thrombophlebitis, anemia secondary to chemotherapy of memo Thrombophlebitis Thrombophlebitis Betrieb y, anemia secondary to AZT therapy, Thrombophlebitis Betrieb y, anemia in myelodysplastic disorders memo Thrombophlebitis prophylactic use during the perioperative Thrombophlebitis Betrieb y to reduce the need for allogenic blood transfusions.
Memo Thrombophlebitis cancer, anemia occurs with varying degrees of frequency and severity. It is most frequent in genitourinary, Thrombophlebitis Betrieb y, gynecologic, lung, and hematologic malignancies. Anemia may be directly related to cancer type or to its treatment. Oncologic anemia occurs by a variety of mechanisms, Thrombophlebitis Betrieb y. Poor oral intake or altered metabolism may Forschung Thrombophlebitis nutrients folate, iron, Thrombophlebitis Betrieb y, vitamin Thrombophlebitis Betrieb y essential for the red cell production.
Antibodies in certain tumor types may cause increased erythrocyte destruction through hemolysis. Tumors may cause blood loss via tissue invasion, e. Other neoplasms, particularly hematologic malignancies leukemia, lymphoma, multiple myeloma can invade the bone marrow and disrupt the erythropoietic microenvironment.
In more advanced cases, there may be marrow replacement with tumor or amyloid. Marrow dysfunction can occur, however, Thrombophlebitis Betrieb y, even in the absence of frank invasion Faquin ; Mikami Inflammatory proteins memo Thrombophlebitis interactions between the immune system and tumor cells are memo Thrombophlebitis to cause inappropriately low erythropoietin production and poor iron utilization as well as a direct suppression of red cell memo Thrombophlebitis.
The treatment of cancer may also cause anemia. Radical cancer surgery can result in acute blood loss. Radiotherapy and many cytotoxic chemotherapeutic agents cause marrow suppression to some degree. Damage is due to a variety of mechanisms. For example, alkylating agents cause cumulative DNA damage, anti-metabolites damage DNA indirectly, and platinum-containing agents appear to damage erythropoietin-producing renal tubule cells.
Myelodysplastic disorders are a heterogenous group of pre-leukemic diseases characterized by cytopenias due to abnormal hematopoietic differentiation and maturation. The disease may be idiopathic or secondary to chemotherapy or radiation therapy for other disease. The primary defect resides in hematopoietic stem cells. Thrombocytopenic bleeding and neutropenic memo Thrombophlebitis contribute to death. Therapeutic here of MDS related anemia requires treatment of the underlying marrow disorder.
Treatment in younger patients is allogenic bone marrow transplantation. Treatment with cytotoxic agents has demonstrated limited utility. In our proposed memo Thrombophlebitis in May of this year, we restricted our proposal to oncologic uses of ESAs. However, as pointed out to us, MDS is not an oncologic condition.
Thus, we are making no decision on MDS in this final decision. The level at which anemia memo Thrombophlebitis intervention is memo Thrombophlebitis well established.
Most of these practices, however, Thrombophlebitis Betrieb y, are based on empiric observations and not clinical trials. In Thrombophlebitis Betrieb y of the few read article, Carson et al. The British Blood Transfusion Society has delineated the weaknesses in our knowledge base. Although they have done so in the past, the College of American Pathologists CAP no longer issues transfusion practice guidelines. Other groups have developed definitions for anemia and memo Thrombophlebitis been cited for these definitions, but these definitions cannot Thrombophlebitis Betrieb y visit web page into guidelines for oncologic treatment.
The World Health Organization WHO definitions for anemia were developed for surveillance of anemia due to nutritional deficiency and parasitic infections.
Medicare is a defined memo Thrombophlebitis program. An item or service must fall within a benefit category as a prerequisite to Medicare coverage. The initial day comment period opened. Erythropoietin-alpha was the first ESA approved by the FDA for use in renal failure Subsequently two ESAs were approved for the management of the anemia of cancer treatment chemotherapy of non-myeloid neoplastic disease: Concerns regarding an increased rate of tumor progression and increased mortality were incorporated into the Precautions Section of product labeling in The briefing information and transcript for the meeting is available at www.
A "black box" warning is the most serious warning placed in the labeling of a prescription medication. FDA also warned that ESAs are not indicated for anemic cancer patients not undergoing treatment and that mortality is increased when ESAs are used by this population.
Specific warnings on the use of ESAs included that they: When making national coverage determinations, CMS evaluates relevant clinical evidence to determine whether or not the evidence is of sufficient quality to support a finding that an item or service falling within a benefit category is reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member.
Critical appraisal of the evidence memo Thrombophlebitis us to determine to what degree Thrombophlebitis Betrieb y are confident that: An improved health outcome is one memo Thrombophlebitis several considerations in determining whether an memo Thrombophlebitis or service is reasonable and necessary. A detailed account of the methodological principles of study design that are used Krampfadern Volksheilmittel für assess the relevant literature on a therapeutic or diagnostic item or service for specific conditions can be found in Appendix B.
In general, features of clinical studies that improve quality and decrease bias include the selection of a clinically relevant cohort, the Thrombophlebitis Betrieb y use of a single good reference standard, the blinding of readers of the index test Thrombophlebitis Betrieb y reference test results. Public comment sometimes cites the published clinical evidence memo Thrombophlebitis gives CMS useful information.
Public comments that give information on unpublished evidence such as the results of individual practitioners or patients are less rigorous and therefore less useful for making a coverage determination. CMS uses the initial public comments to inform its proposed decision. CMS responds in detail to the public comments on a proposed decision when issuing the final decision memorandum. We are providing a summary of the evidence that we considered during memo Thrombophlebitis review.
We refer the reader to Appendix A for a full discussion. This section presents the agency's evaluation of the evidence considered for the assessment questions: Is the evidence sufficient to conclude that erythropoiesis stimulating agent therapy affects health outcomes when used by Medicare beneficiaries with cancer and Thrombophlebitis Betrieb y neoplastic conditions?
If the memo Thrombophlebitis to Question 1 is affirmative, what characteristics of the patient, the disease, Thrombophlebitis Betrieb y, or the treatment regimen reliably predict a favorable or unfavorable health outcome? Memo Thrombophlebitis will review each of the questions in the context of our proposed individual coverage criteria separately, respond memo Thrombophlebitis comments on that recommendation, discuss any new evidence, and provide our response with any proposed changes, Thrombophlebitis Betrieb y.
Our responses to comments on aspects of the proposed decision other than the proposed coverage criteria are summarized in the Comment Section. Multiple studies have raised significant safety concerns about the potential for ESAs to increase tumor progression and decrease survival in cancer patients.
Although some of these were studies Thrombophlebitis Betrieb y ESAs used during radiotherapy or for anemia of cancerboth off-label usesthe data nonetheless raises concerns about the use of Thrombophlebitis Betrieb y for all memo Thrombophlebitis indications to include labeled indications. In concert with our general methodologic principles Appendix Bwe believe that in Varizen besten Moskau Kliniken Thrombophlebitis Betrieb y in instances, this evidence can only be obtained in randomized controlled trials, Thrombophlebitis Betrieb y.
Our review of other literature memo Thrombophlebitis to shed light on the memo Thrombophlebitis underlying biological processes Krampfadern und Behandlungen may account for the trial findings. We remain concerned that a number of memo Thrombophlebitis have been terminated, suspended, or otherwise not completedpossibly due to signals of harmand that the existing fund of published evidence may reflect a bias toward ESA use.
Transparent public access to clinical trial datasets, as opposed memo Thrombophlebitis data summaries, would enhance public confidence in this http: Please refer to the Proposed Decision Memorandum for a review of this matter.
A well-defined strategy or memo Thrombophlebitis established before the results of memo Thrombophlebitis studies are known is optimal. CMS staff extensively searched Medline to memo Thrombophlebitis for primary studies evaluating Memo Thrombophlebitis therapy Thrombophlebitis Betrieb y cancer and related conditions, Thrombophlebitis Betrieb y.
The emphasis was on studies structured to assess adverse events and mortality, Thrombophlebitis Betrieb y. Systematic reviews were used to help locate some of the more obscure publications and abstracts. Preference was given to English publications. Because much of the material remains outside the domain of the published medical literature, additional sources were used. CMS examined FDA reviews of memo Thrombophlebitis registration trials for epoetin and darbepoetin alpha as well as the FDA safety data for epoetin and darbepoetin alpha.
CMS used internet searches to identify websites with clinical trial results, press releases for clinical trial termination, and U. We catalogued these trials in our proposed decision Appendix A. Following the release of the proposed NCD on May 14,we received some additional references, primarily non-Medline publications, Thrombophlebitis Betrieb y. We also updated our search and broadened it to be more inclusive for Memo Thrombophlebitis and multiple myeloma.
We received over additional citations as comments. Many of these addressed memo Thrombophlebitis blood supply, transfusion errors and erythropoietin receptors. We received many articles that duplicated items in our library.
