Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Any age
  • Women only
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: Pregnant women with MS or CD who were exposed to Tysabri® in the US, Canada, and the Rest of World within 90 days prior to their last menstrual period.

Who may be able to join

  • Females who become pregnant while they are taking TYSABRI® as part of the TYGRIS program, during a clinical trial with TYSABRI® that is sponsored by Biogen-Idec, or in the post-marketing setting may enroll in this Registry, as follows:
  • Documentation that the patient was exposed to TYSABRI® within 90 days prior to first day of Last Menstrual Period (LMP) or during pregnancy. (If exposure dates are unknown, the reporter must be able to specify or estimate trimester of exposure).
  • The outcome of the pregnancy must not be known at the time of enrollment. For pregnancies for which the outcomes are known at the time of enrollment, the information will be collected as retrospective reports and analyzed separately.
  • For US patients, verbal informed consent must be collected at the time of enrollment. The Coordinating Center (CC) obtains verbal informed consent (if verbal consent has not already been obtained by the physician). The CC then mails the patient a Release of Medical Information form to sign and return. If the patient is a minor, verbal consent must be obtained from the parent or legal guardian and verbal assent must be obtained from the patient.
  • For Canadian patients, a written informed consent must be collected by the TYGRIS investigator at the time of enrollment. A Release of Medical Information form will also be signed by the patient and returned to the CC.
  • NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

What are the possible benefits and risks?

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of spontaneous abortions, fetal losses including stillbirths, and ectopic pregnancies (time frame: Approximately 9 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00472992, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
