Post-Market Clinical Follow-up Study With the ASPIREX®S Endovascular System to Assess the Safety and Effectiveness in the Treatment of DVT Patients and Special Patient Groups

The ASPIREX®S Endovascular System is a rotating and aspirating catheter system. It is intended to be used for the percutaneous transluminal removal of fresh thrombotic or thromboembolic material from native blood vessels (or vessels fitted with stents, stent grafts or native or artificial bypasses) outside the cardiopulmonary, coronary and cerebral circulations.
CAPTUREX® , a catheter with a filter basket, is intended to be used for the filtering of emboli from blood vessels during potentially embolizing procedures on the patient.
ASPIREX®S and CAPTUREX® are CE-marked (Class III) medical devices. In this study the effectiveness and safety in the removal of thrombi in veins is assessed under real life setting.

DT-0111: a novel P2X3 receptor antagonist.

Article

作者: Mahadevan, Anu ; Rolland, Jean-Francois ; Sirtori, Elena ; Pelleg, Amir

Extracellular ATP (ATP) acts as an autocrine and paracrine agent, the actions of which on affected cells are mediated by P2 receptors (P2R), which include trans cell-membrane cationic channels (P2XRs), and G protein coupled receptors (P2YRs).The mammalian P2X receptors form homotrimeric or heterotrimeric cationic channels, each of which contains three ATP-binding sites.There are seven homotrimeric P2X receptors (P2X1-7) and three heteromeric (P2X2/P2X3, P2X4/P2X6, P2X1/P2X5).In the lungs and airways, ATP activates P2X3 and P2X2/3 receptors (P2X3R, P2X2/3R, resp.) localized on vagal sensory nerve terminals resulting in bronchoconstriction, and cough, and probably also localized release of pro-inflammatory neuropeptides via the axon reflex.Currently, several P2X3R and P2X2/3R antagonists are being developed as drug-candidates for the treatment of chronic cough.This report presents the receptor affinity data of a novel water-soluble small mol., DT-0111, that acts as a selective P2X3R antagonist.

OBJECTIVEThis is a retrospective study on Pharmacomechanical Catheter-Directed Thrombolysis (PCDT) in the treatment of acute iliofemoral Deep Vein Thrombosis (DVT).PATIENTS AND METHODSFrom March 2013 to November 2016, 22 patients (26 limbs), median age 46.7 years with acute (<21 days) extensive iliofemoral DVT underwent Percutaneous Mechanical Thrombectomy (PMT) with Aspirex (Straub Medical, Wangs, Switzerland), followed by Catheter-Directed Thrombolysis (CDT). Subsequent endovascular stenting was performed for underlying obstruction. The follow-ups were conducted up to 1 year, in two Centers by experienced operators. Post-Thrombotic Syndrome (PTS) was evaluated by assessing the Villalta Scale (VS) and measuring orthostatic venous pressure.RESULTSPost-operative iliofemoral vein patency was restored in almost all cases (95.5%). Standard urokinase dose was 80.000 IU per hour; mean infusion time was 32.5 hours. Stenting was performed in 15 cases (68%). Median follow-up was 19.9 months (6-48 months); 21/22 patients completed the 12 months follow-up. At 30 days follow-up symptoms disappeared in 21/22 cases (95.5%), with one case (4.5%) of DVT recurrence. At 1-year follow-up there were 3 cases (14.2%) of mild PTS; 18 patients (85.8%) were free from PTS. At 1-year follow-up venous pressure measurement showed normal values in 11 cases (52.4%), mild hypertension in 7 patients (33.3%), moderate hypertension (80-100 mmHg) in 2 cases (9.5%) and severe hypertension (110 mmHg) in one case (4.8%). Neither major nor minor complications were observed.CONCLUSIONSPMT with Aspirex combined with CDT with urokinase seems to be a safe and effective treatment for acute iliofemoral DVT and it shows promising results in reducing the risk of PTS. Thus, we suggest a controlled trial with this treatment strategy.

DT-0111: a novel drug-candidate for the treatment of COPD and chronic cough

Background: Extracellular adenosine 5′-triphosphate (ATP) plays important mechanistic roles in pulmonary disorders in general and chronic obstructive pulmonary disease (COPD) and cough in particular. The effects of ATP in the lungs are mediated to a large extent by P2X2/3 receptors (P2X2/3R) localized on vagal sensory nerve terminals (both C and Aδ fibers). The activation of these receptors by ATP triggers a pulmonary-pulmonary central reflex, which results in bronchoconstriction and cough, and is also proinflammatory due to the release of neuropeptides from these nerve terminals via the axon reflex. These actions of ATP in the lungs constitute a strong rationale for the development of a new class of drugs targeting P2X2/3R. DT-0111 is a novel, small, water-soluble molecule that acts as an antagonist at P2X2/3R sites. Methods: Experiments using receptor-binding functional assays, rat nodose ganglionic cells, perfused innervated guinea pig lung preparation ex vivo, and anesthetized and conscious guinea pigs in vivo were performed. Results: DT-0111 acted as a selective and effective antagonist at P2X2/3R, that is, it did not activate or block P2YR; markedly inhibited the activation by ATP of nodose pulmonary vagal afferents in vitro; and, given as an aerosol, inhibited aerosolized ATP-induced bronchoconstriction and cough in vivo. Conclusions: These results indicate that DT-0111 is an attractive drug-candidate for the treatment of COPD and chronic cough, both of which still constitute major unmet clinical needs. The reviews of this paper are available via the supplementary material section.
