The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Objectives The study is a prospective, non-randomized open-label concurrent control study of NovoTTF-100A in recurrent GBM patients. A prospective, international, multi-center study, will include 30 centers in the US, EU and Israel, at least 15 centers in the US.

The study will include 2 groups: an Investigational Group composed of patients treated with the NovoTTF-100A and a Control Group of concurrent best standard of care chemotherapy.
Patients in the NovoTTF-100A group will be treated continuously until disease progression and then followed by telephone interview until death. Minimal recommended treatment duration is 4 weeks and minimal recommended treatment compliance is 18h/day (monthly average).
Study Population The NovoTTF-100A System is intended as a treatment for adult
patients (22 years of age or older) with histologically-confirmed
glioblastoma multiforme (GBM), following histologically- or
radiologically-confirmed recurrence in the supra-tentorial
region of the brain after receiving chemotherapy.

NovoTTF-100A Group
¿ Patients treated with the NovoTTF-100A
¿ Patients will be treated continuously until disease
progression
¿ Minimal recommended treatment duration ¿ 4 weeks
¿ Minimal recommended treatment compliance ¿ 18h a day
(monthly average)

Control Group
¿ Concurrent best standard of care chemotherapy (control) group
Sample Size 30 centers in the US, EU and Israel. At least 15 centers in the
US.

Test arm: N1=243 NovoTTF-100A patients
Comparator arm: N2=243 Concurrent best standard of care
control patients

Definitions:
λ1 = hazard of death in the test arm
λ2 = hazard of death in the comparator arm
Primary Statistical Hypothesis:
H0: λ1 / λ2 > 1.375
H1: λ1 / λ2 ≤ 1.375
Assumptions:
Type I error: 0.05
Power: 0.80
Test statistics: Log-rank test
Lost to follow-up: 10%
Key Study Endpoints Primary
¿ Overall survival (months)

Secondary
¿ Change in neuro-cognitive function from baseline based on the MMSE
¿ Genetic profiling of tumors and correlation with response
to NovoTTF-100A treatment, specifically:
o MGMT promoter methylation status
o EGFR amplification, over expression or rearrangement
o Chromosomes 1p/19q deletion status
o IDH1 mutation
¿ Adverse event incidence by body system and term,
including:
o Incidence of seizures and headaches
o Anticonvulsant use
Follow-up Visits and Length of Follow-up ¿ Recruitment: 48 months
¿ Follow-up: 12 months from recruitment of last patient
¿ NovoTTF-100A treatment until clinical disease progression.
¿ Patients will continue to be followed until death
Baseline:
¿ Eligibility assessment
¿ MMSE
¿ Genetic profiling of tumor tissue
¿ Adverse event symptoms
¿ Concomitant medication
Monthly until clinical disease progression:
¿ Vital status
¿ MMSE
¿ Adverse event record
¿ Concomitant medication (including steroid and anticonvulsant
dosing)
¿ Evaluation of progression
Monthly after disease progression:
¿ Vital status
