What are the difficulties in conducting randomised controlled trials of thromboprophylaxis in myeloma patients and how can we address these? Lessons from apixaban versus LMWH or aspirin as thromboprophylaxis in newly diagnosed multiple myeloma (TiMM) feasibility clinical trial

AbstractRoutine thromboprophylaxis (TP) in newly-diagnosed multiple myeloma (NDMM) patients comprises either aspirin for standard risk patients or low molecular weight heparin for high risk patients. Studies using DOACs in cancer patients include few with myeloma. The aim of this feasibility clinical trial was to establish the foundations for creating a multicentre trial and identify any safety concerns with apixaban. Patient perspectives were sought. NDMM patients were stratified according to VTE risk and randomised to either standard TP or apixaban 2.5  mg BD and reviewed every 3 weeks throughout their chemotherapy. Two focus groups were carried out on 2 occasions at King’s College Hospital and Guy’s Hospital, London. Each lasted an hour, were recorded, transcribed and themes explored using NVivo 11. Ten patients were recruited, 2 considered high risk and received apixaban and 8 standard risk; 4 randomised to aspirin and 4 to apixaban. Five patients and 2 carers participated in the focus groups. There were no major bleeding or VTE events. Patients were not aware of the thrombotic risk associated with cancer. There is a lack of both wri tten and verbal information on this topic. Myeloma patients were happy to be included in more than one trial simultaneously. Our study provides information on the difficulties facing physicians and patients on obtaining evidence of the safety of DOACs in the context of myeloma. Despite patients bein g happy to co-recruit...

Hematological cancer has risk of venous thromboembolism of 28 fold compared to sex and age adjusted incidence in general population (JAMA 2005;293:715-722). This risk increases in patients with MM receiving dexamethasone and immunomodulatory drug. Thus, thromboprophylaxis with aspirin in low risk patients and LMWH or warfarin in high risk patients are recommended (Leukemia 2008;22:414-423). Direct oral anticoagulants are promising due to their convenience and costs-effectiveness in preventing VTE in other settings. They have not been extensively studied in myeloma therapy.From January of 2010 to December of 2017, 105 with ...

Conclusion: This study provided laboratory evidence of hemostatic dysfunction which may be associated with thrombotic or bleeding complications at diagnosis in all MM patients. Hence, screening for these abnormalities at the time of diagnosis should help improved prognosis in such cases. PMID: 29373903 [PubMed - as supplied by publisher]

CONCLUSIONS: In this second update, we confirmed that primary thromboprophylaxis with LMWH significantly reduced the incidence of symptomatic VTE in ambulatory cancer patients treated with chemotherapy. In addition, the uLMWH semuloparin, which is not commercially available, significantly reduced the incidence of symptomatic VTE. The risk of major bleeding associated with LMWH, while not reaching statistical significance, suggest caution and mandate additional studies to determine the risk-to-benefit ratio of LMWH in this setting. Despite the encouraging results of this review, routine prophylaxis in ambulatory cancer pati...

Conclusion: Duration of anticoagulation should comply with guidelines. Prophylaxis with LMWH is mandatory for hospitalized patients with previous VTE history. Major bleeding risk is low and shouldn't be a reason for inadequate treatment or prophylaxis.

This article discusses hematologic diseases in adult patients, and categorizes them into benign and malignant conditions. The more common benign hematologic diseases associated with neurologic manifestations include anemias, particularly caused by B12 deficiency and sickle cell disease, and a variety of disorders of hemostasis causing bleeding or thrombosis, including thrombotic microangiopathy. Malignant conditions like multiple myeloma, leukemias, and lymphomas can have neurologic complications resulting from direct involvement, or caused by the different therapies to treat these cancers.

Conclusion Ambulatory patients with multiple myeloma who are considered for immunomodulatory drug therapy should be placed on pharmacologic thromboprophylaxis based on individual venous thromboembolism and bleeding risk factors. This study identified the need for increased adherence to national guidelines for venous thromboembolism prevention in patients with multiple myeloma receiving immunomodulatory drug therapy so as to increase the quality of care provided at UC Health.
