Protection of trial subjects |
Pediatric Subjects: The study was conducted by investigators experienced in the treatment of pediatric subjects. The parent(s) or guardian(s) as well as the children were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time. In addition to the consent form for the parent(s)/guardian(s), an assent form in child-appropriate language was provided and explained to the child.
Adult Subjects: Subjects were fully informed of all pertinent aspects of the clinical trial as well as the possibility to discontinue at any time in language and terms appropriate for the subject and considering the local culture. During the course of the trial, subjects were provided with individual subject cards indicating the nature of the trial the subject is participating, contact details and any information needed in the event of a medical emergency.
Collected personal data and human biological samples were processed in compliance with the Sanofi-Aventis Group Personal Data Protection Charter ensuring that the Group abides by the laws governing personal data protection in force in all countries in which it operates.

Recruitment
|
|||||||||||||||||||||||||||||||||
Recruitment details |
The study was conducted at 33 centers in 7 countries. A total of 144 subjects were enrolled in the study. 1 subject never received study drug. 2 of the enrolled subjects came from a phase 2 study and its extension and consequently had very different treatment from the other treated subjects, and thus were excluded from all summary tables. | ||||||||||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||||||||||
Screening details |
Subjects who successfully completed ISIS 301012-CS5 (NCT00607373), ISIS 301012- CS7 (NCT00706849), ISIS 301012-CS17 (NCT00694109) or MIPO3500108 (NCT00794664) with an acceptable safety profile were eligible for study. | ||||||||||||||||||||||||||||||||

Amendment |

24 Aug 2007 |
It included the following changes:
- The dose regimen was changed from 200 mg every other week with dose-titration to effect to 200 mg once a week without the option to dose-titrate to effect. - In addition, it reduced the treatment period from 2 years to 6 months in accordance with the extension of the
treatment period in the studies that were to roll into this open-label extension study. - It also modified the protocol to include subjects who completed study ISIS 301012-CS7. - Other modifications were made to maintain consistency between this study and other ongoing mipomersen clinical trials. The background information for the drug was updated to reflect the status of the mipomersen development program and to be consistent with the Investigator’s Brochure. - Minor changes were also made to improve the overall clarity of the original protocol. |
||
17 Jul 2008 |
It included the following changes: - This amendment indicated that sponsorship was transferred from Isis Pharmaceuticals, Inc. to the Genzyme Corporation. - The safety reporting information was updated to provide contact information for the Genzyme Pharmacovigilance Department. - Modifications were made to extend dosing of mipomersen from 26 weeks to 52 weeks for the purpose of obtaining additional long-term safety and efficacy data. - Minor changes were also made to improve the overall clarity of the protocol and to align the text with the Investigator’s Brochure. |
||
24 Aug 2009 |
It included the following changes: Dosing of mipomersen was extended from 52 weeks to 104 weeks for the purpose of obtaining additional long-term safety and efficacy data. - Included subjects who completed study MIPO3500108, which expanded the population to include subjects with severe hypercholesterolemia. The title of the study was updated to reflect this change. - Safety monitoring and stopping rules were revised to reflect information from the larger safety database. - This amendment also allowed for temporary dose adjustment for liver chemistry elevations, as well as for injection site reactions and constitutional symptoms leading the subject to consider discontinuation from the study. - Added a new section to the protocol recommending magnetic resonance imaging (MRI) or computed tomography (CT) scanning if clinically indicated. - This amendment noted that additional pharmacokinetic (PK) samples were to be drawn (not just for trough levels), in order to determine peak mipomersen levels after dosing. - Minor changes were also made to improve the overall clarity of the protocol and to align the text with the Investigator’s Brochure. |
||
17 Feb 2010 |
It included the following changes: - Included MRI assessments of liver fat fraction at approximately 6-month intervals during the study. These MRI assessments were added to provide further characterization of potential changes in liver fat with long-term treatment with mipomersen. - In addition, it included a metabolomics analysis, which was added to help in understanding the cellular mechanisms underlying any imaging findings observed. - Other changes included minor changes to safety monitoring rules and clarifications made to study conduct and corrections to minor inconsistencies. |
||
18 May 2011 |
It included the following changes: - Extended dosing from 2 years to 4 years or until mipomersen was commercially available (whichever came first) for the purpose of obtaining additional long-term safety and efficacy data.
- Included that subjects must establish sufficient sustained efficacy throughout the treatment period per Investigator judgment, such as ≥15% LDL-C reduction from the subject's primary study baseline value, regardless of dosing regimen.
- Dose adjustment instructions were modified to align with current development plans for mipomersen, specifically, to offer an alternative dosing regimen (70 mg thrice per week) for subjects with intolerable injection site reactions or flu-like symptoms with the 200 mg per week
injections and to extend the dose interval for subjects with liver enzyme elevations (200 mg every other week).
- Included additional post-dose serial PK blood samples for the purpose of further exploring the PK profile after mipomersen administration. |
||
12 Sep 2011 |
It included following changes:- Biopsy data collected in order to evaluate whether hepatic abnormalities were present in subjects
who had already completed, or were expected to complete, more than 2 years of treatment.
- Blood samples collected at the visits specified on the schedule of events and stored specifically for hepatic biomarker testing. |
