Reporting Groups

	Description
Placebo/Fabrazyme	Patients who had been randomized to placebo during AGAL-008-00 (NCT00074984) and were then transitioned to open-label Fabrazyme (1.0 mg/kg every 2 weeks) prior to or at entry to AGAL02503 (NCT00081497).
Fabrazyme/Fabrazyme	Patients who had been randomized to Fabrazyme in AGAL-008-00 (NCT00074984) and were then transitioned to open-label Fabrazyme (1.0 mg/kg every 2 weeks) prior to or at entry into AGAL02503 (NCT00081497).

Certain Agreements:

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: In multi-site studies, Principal Investigator (PI) can publish after Genzyme publishes or 18 months after study completion. PI gives Genzyme a draft 60 days before publication. Genzyme can ask that confidential information be removed, and can defer publication another 60 days upon notifying PI that it will file a patent application on inventions contained in the draft.

Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
No valid conclusions can be made from the predefined primary efficacy analysis. The sponsor believes that it is more statistically appropriate to compare placebo patients with Fabrazyme patients as they were randomized in the original Phase 4 trial.
