Endovenous interventions are keyhole operations for varicose veins that are carried out from within the vein itself. Varicose veins are enlarged veins close to the surface of the skin. They are connected to the bigger deeper veins in the leg (known as deep veins). Because of this, operations to close the varicose veins can increase the chance of a blood clot forming in the deep veins. Blood clots in the deep veins happen in around 1 in 50 people after endovenous operations. A clot in the leg can cause swelling, pain, and other long-term problems. If a clot in the leg breaks off and travels to the lungs, it can cause problems with the lung' ability to move oxygen from the air into the blood and may, in rare cases, be life threatening.
Varicose vein procedures may carry a slightly higher risk of blood clot formation, and we are currently unsure if current clot reducing medicines are beneficial in preventing blood clots in people having varicose vein procedures.
This study will investigate if it is worthwhile prescribing medicines to reduce blood clots after varicose vein procedures.

Prophylaxis of Venous Thromboembolic Disease With Low Molecular Weight (LMWH) (TINzaparin) in Patients With Metastatic Colorectal Cancer Who Start the First Line of Treatment.

Patients with metastatic colorectal cancer (mCRC) who are scheduled to receive systemic cancer therapy have an increased risk for venous thromboembolic (VTE) events compared with the general population.
PROTINCOL is a randomized, open label, non placebo-controlled, low intervention, and phase III clinical trial that will recruit patients with mCRC. The study hypothesizes that prophylaxis with Tinzaparin could prevent the appearance of symptomatic and incidental VTE.
All patients will receive the first-line anticancer treatment deemed more appropriate according to the physician criteria. Enrolled patients are randomized in a 1:1 ratio (stratifying by BRAF/RAS, resection of primary tumor, and anti-angiogenic first-line treatment) to: control arm (no interventions related to VTE risk and no placebo) or experimental arm (prophylactic Tinzaparin at a fixed dose of 4500 IU/day in patients with up to 80kg, 6000 IU/day for those between 80-100 kg, or 8000 IU/day for those >100kg). Treatment is scheduled for a maximum period of 4 months. Treatment could be stopped earlier in case of unacceptable toxicity, patient consent withdrawal, physician criteria or end of study. Patients will undergo tumor and VTE assessments according to standard clinical practice.
The main objective of the study is to evaluate the efficacy of tinzaparin for the prevention of symptomatic or incidental VTE events. Secondary objectives include the associations between VTE events and tumor characteristics (i.e. laterality, RAS/BRAF mutations) or management (i.e. surgery or treatment with anti-angiogenic or anti-EGFR agents), cancer-specific survival outcomes, safety, the incidence of bleeding events, and patient-reported quality of life. The trial includes also a translational exploratory analysis to assess the predictive value of risk assessment models and genetic risk scores, their evolution through the study and microsatellite instability or other biomarkers.

STrategies for Anticoagulation in Patients With thRombocytopenia and Cancer-associated Thrombosis

Patients with cancer are prone to have blood clots, which are usually treated with blood thinners. The main complication of blood thinners is bleeding. This is especially a concern when the number of platelets in the blood is lower than 50,000 per microliter. The role of platelets is to stop bleeding, so when the number of platelets is low, patients are at a higher risk of bleeding. Cancer patients are prone to have lower platelet numbers due to cancer therapies and/or cancer itself. It is not clear what the best treatment is for cancer patients who need blood thinners for a blood clot but have low platelet counts.
The investigators plan to do a small study called a pilot study to help plan for a larger study in such patients. In the pilot study, investigators will include 50 patients with cancer, low platelet counts, and a blood clot diagnosed within 4 weeks. Patients will be randomly assigned to one of the two treatment strategies: the full dose of blood thinners along with platelet transfusion or a reduced dose of blood thinners without platelet transfusion. The investigators will follow all patients for 90 days. If this pilot study is successful, it will help lead to a much larger trial, which will provide important information on the best treatment strategy in these patients.

Tinzaparin, an alternative to subcutaneous unfractionated heparin, in patients with severe and end-stage renal impairment: a retrospective observational single-center study

Article

BACKGROUND:

Tinzaparin could be easier to manage than unfractionated heparin in patients with severe renal impairment. However, clinical and pharmacologic data regarding its use in such patients are lacking.

OBJECTIVES:

The aims of this study were to determine, in patients with estimated glomerular filtration rate (eGFR) of <30 mL.min⁻¹, tinzaparin pharmacokinetics (PK) parameters using a population PK approach and bleeding and thrombotic complications.

METHODS:

We performed a retrospective observational single-center study, including in-patients with eGFR of <30 mL.min⁻¹ receiving prophylactic (4500 IU.d⁻¹) or therapeutic (175 IU.kg⁻¹.d⁻¹) tinzaparin. Measured anti-Xa levels were analyzed using a nonlinear mixed-effects modeling approach. Individual predicted tinzaparin exposure markers at steady state were calculated for each patient and dosing regimen. The PK was also evaluated through Monte Carlo simulations based on the final covariate model parameter estimates.

RESULTS:

Over a 22-month period, 802 tinzaparin treatment periods in 623 patients were analyzed: two-thirds received a prophylactic dose, 66% had an eGFR of <20 mL.min⁻¹, and 25% were on renal replacement therapy. In patients for whom anti-Xa measurements were performed (n = 199; 746 values), PK parameters, profiles, and maximum plasma concentrations were comparable with those in patients without renal impairment or in healthy volunteers. In the whole population, major bleeding occurred in 2.4% and 3.5% of patients receiving prophylactic and therapeutic doses over a median 9- and 7-day treatment period, respectively. No patients had thrombotic complications.

CONCLUSION:

Tinzaparin PK parameters and profiles were not affected by renal impairment. This suggests that tinzaparin, at therapeutic or prophylactic dose, could be an alternative to unfractionated heparin in hospitalized patients with severe renal impairment.

Promising Drug Fondaparinux for the Treatment of COVID-19: an In Silico Analysis of Low Molecular Weight Heparin, Direct Oral Anticoagulant, and Antiplatelet Drug Interactions with Host Protease Furin

Article

Author: Bolelli, Kayhan ; Belen-Apak, F Burcu ; Ertan-Bolelli, Tugba ; Elçi, Sıtkı Doga

PURPOSE:

As of July 2022, the COVID-19 pandemic has affected over 555 million worldwide confirmed cases and caused more than 6.3 million deaths. The studies showed that the D-dimer levels were increased in non-survivors compared to survivors and heparin treatment has begun to be administered to the patients in severe clinics. As we knew that the entrance of SARS-CoV-2 to the host cell needs to be facilitated by host proteases; we published our hypothesis that heparin as a serine protease inhibitor may block the interaction between spike protein receptor-binding domain and host proteases. In our study, we aimed to investigate the interactions between not only heparins but also other antiplatelet and anticoagulant drugs including fondaparinux.

METHODS:

In this study, docking studies were carried out to evaluate the interactions between low molecular weight heparins (LMWHs) (enoxaparin, dalteparin, tinzaparin), direct oral anticoagulant, and antiplatelet drugs with host proteases. Molecular docking studies were performed by using Schrödinger molecular modeling software. 3D structures of the ligands were obtained from the 2D structures by assigning the OPLS-2005 force field using the Maestro 12.7. The 3D crystal structure of the furin complexed with an inhibitor, 2,5-dideoksistreptamin derivative, was extracted from the Protein Data Bank (PDB ID: 5MIM). Docking studies were carried out using the Grid-based Ligand Docking with Energetics module of the Schrödinger Software.

RESULTS:

The docking studies revealed that fondaparinux was the most relevant molecule to interact with furin with a docking score of - 12.74. It showed better interaction than the natural ligand of furin with an increased score compared to the docking score of - 8.155 of the natural ligand. AnaGA*IsA structure representing LMWH structure has shown a docking score of - 11.562 which was also better than the score of the natural ligand of furin.

CONCLUSION:

Our findings have shown that LMWHs and fondaparinux can be used for their possible antiviral effects in COVID-19 patients. Our results have shown that in accordance with heparin and LMWH, fondaparinux can also be a candidate for "drug repurposing" in COVID-19 therapy, not only because of their anticoagulant but also possible antiviral effects.

Low molecular weight heparins, such as Fragmin (-11.8%) and Innohep (-14.1%), have seen a significant decrease in the market. The anticoagulant drug market will continue to grow at a slow rate compared to antiplatelet and thrombin inhibitors segment due to the lack of new drug launches since the expiration of the patent on Plavix. The anticoagulant segment is expected to decline soon as prices fall and the market for novel thrombin inhibitors grows. The market for thrombin inhibitors is expected to grow at the highest CAGR of 8.1% over the forecast period of 2023 to 2028. Xarelto (rivaroxaban), Eliquis (apixaban), TNKase (tenecteplase) and Savaysa (edoxaban) are the major contributors to the high growth rate of thrombin inhibitors. An aging population and the increased prevalence of cardiovascular disease worldwide fueled by a Westernized diet and lifestyle have created new opportunities for antithrombotic/ anticoagulant drug products.
