Report

Regulations in Israel
Israel
Regulated by the Ministry of Health
(MoH); Legislated by national laws
 MoH has two departments:
• Device – ISO 14155 for the conduct of
clinical trials
• Drug
trials
– ICH GCP for conduct of clinical
Combination products are usually reviewed by the drug
department of the MoH

Site Selection
 Site selection is normally an activity of the
sponsor although it is discussed with the
CRO.
 In this case study, based on their
experience, the sponsor identifies good
centers and investigators who can provide
reasonable patient numbers.

Patient Enrollment

Poor patient enrollment in the US

Europe and Israel enrolled 72% of patients

Conclusion: site selection, patient enrollment
can be difficult – proper site assessment,
qualification, ability to generate good quality
data and experience is necessary.
40
Monitoring Visits
Follow-Up Visits Required:
 1, 6, 12 months, and then yearly up to 5 years
total, for all patients undergoing at least
primary randomization
 Angiography at 13 months for 1,500 stent
randomized patients only
41
Study Close Out
 The study was terminated early (truncating the
study from 5 years to 3 years). The FDA, IRB,
competent authorities, and ethics committees
were informed.
 The study outcome was achieved within 3 years.
42
Final Report
 The database was locked on 4 November 2010.
 The final report was submitted to the FDA
on 11 November 2010.

Study Conclusions
 A significant 34% reduction in major bleeding
and a significant 24% reduction in reinfarction,
with comparable rates of stent thrombosis, target
vessel revascularization and stroke is
maintained to three years.
46
Study Conclusions
 The improvement in survival in patients treated
with anticoagulant B is maintained to three years
with a significant 44% reduction in cardiac
mortality and a 25% reduction in all-cause
mortality.
47
Study Conclusions
 The DES group continues to show superiority for
the primary efficacy endpoint of ischemic target
lesion revascularization (TLR) with a 40%
reduction and no evidence of late catch-up at
three years.
48
Study Conclusions
 The DES showed superiority over the
BMS when used in combination with
anticoagulant B.

Importance of Clinical Investigations to
establish evidence based medicine
50
Clinical Regime
This has resulted in a change in clinical
regime for patients with ST Elevated MI and
incorporated into:
“ACC/AHA Guidelines for the Management
of Patients With ST-Elevation Myocardial
Infarction.”
51
The Lancet
 December 2011 Volume 378, Issue 9807,
 Bivalirudin for patients with ST-elevation
myocardial infarction
 Gregg Stone and colleagues assessed the sustained benefit of
bivalirudin monotherapy at 3 years for patients with ST-elevation
myocardial infarction (STEMI) who underwent primary percutaneous
coronary intervention. Stone and colleagues report that the long-term
benefit in the bivalirudin group was consistent with delayed effects from
reduction in major bleeding.
52
Combining mechanical reperfusion and
pharmacologic therapy to improve
myocardial perfusion
 Establishes Primary Percutaneous Coronary Intervention (PCI) to
restore coronary blood flow as the current standard of care for STelevation myocardial infarction Now additional resources are utilized by
hospitals and clinicians to achieve this goal.
 Door-to-balloon time of less than 90 minutes as one of the core
performance measure to motivate clinicians and hospitals to adhere to
this important class IA recommendation of American College of
Cardiology (ACC)/ American Heart Association (AHA) guidelines.
