Cardiosonic Begins Enrollment in the TIVUS I Renal Denervation Trial

April 24, 2013

April 24, 2013 — Cardiosonic Inc. announced the completion of the first phase of patient enrollment in its first-in-man (FIM) TIVUS I clinical study. The study is designed to collect data on the safety and performance of the TIVUS System, a high intensity, non-focused therapeutic ultrasound catheter system for remote tissue ablation for the treatment of hypertension by renal denervation (RDN).

The study enrolled the first five patients at Royal Perth Hospital (RPH), Australia and patient screening is continuing. Sharad Shetty, M.D., principal investigator at RPH, completed the procedures with a 100 percent acute success rate in accessing the vessels and delivering therapy. “The performance of renal denervation with an advanced, ultrasonic catheter has been shown to be quick, easy and seems to be associated with minimal pain. The TIVUS System by Cardiosonic has great potential to become an important technology for management of resistant hypertensive patients,” commented Shetty. Shetty will present interim results from the FIM trial at the Euro PCR conference, Paris, May 21 to 24.

The company completed extensive bench and animal studies and following these initial human results is submitting its next human clinical trial to 20 sites worldwide. Krishna Rocha-Singh, an advisor to the company and a leader in the rapidly growing field of RDN, from the Prairie Heart Institute at the St. John’s Hospital in Springfield, Ill., commented that, “The TIVUS system has great potential to improve the process and outcomes of RDN procedures. In addition the TIVUS system may expand the population of patients eligible for RDN therapy by obviating current anatomic and physiologic restrictions and contra-indications.”

Benny Dilmoney, Cardiosonic CEO, commented that, “We are enthusiastic about completing the first phase of enrollment and progressing towards completion of our FIM patients recruitment and follow-up. Cardiosonic has completed the development of our second generation multi-directional catheter and initiated submission for its study at 20 centers worldwide. We believe that this advanced catheter design will further improve RDN procedures.”

Renal Sympathetic Denervation: a Rapidly Evolving Field

Written by Dr. Sebastian Mafeld – Radiology Specialist Registrar, Freeman Hospital, Newcastle upon Tyne, UK and Dr. Gerard S Goh – Consultant Interventional Radiologist, St. George’s Healthcare NHS Trust, London, UK.

The 11/27/2012 paper HAS IGNORED THE ALREADY PUBLISHED LITERATURE IN THE FIELD – nothing of the mentioned in it is NEW or innovative — in 2012 that is intolerable !!

The Scientific Honesty is at Stack

PNAS Study: 2/3 of Retractions in Scientific Journals represents Fraud, Duplicate publication, and Plagiarism (Misconduct).

‘We Have a Problem in Science’

October 02, 2012

A recent study in the Proceedings of the National Academy of Sciences found that more than two-thirds of 2,000 retractions in the life science literature were attributable to some form of misconduct, including fraud, duplicate publication, and plagiarism.

The study, led by Arturo Casadevall of Albert Einstein College of Medicine, estimates that the percentage of scientific papers retracted because of fraud has increased more than 10-fold since 1975.

Carl Zimmer notes in The New York Times that previous studies have concluded that most retractions were attributable to “honest errors,” but the new study “challenges that comforting assumption.”

The authors compiled more than 2,000 retraction notices published before May 3, 2012, and then dug into the reasons behind each retraction. Some reasons were cited by the journals, but the authors also found that the retraction notices for some papers did not cite fraud as the reason for the retraction.

The rise in fraudulent papers “is a sign of a winner-take-all culture in which getting a paper published in a major journal can be the difference between heading a lab and facing unemployment,” Zimmer says.

According to Casadevall, the fact that “some fraction of people are starting to cheat” should not be taken lightly, even if the overall number of fraudulent papers is relatively low. “It convinces me more that we have a problem in science,” he says.
