Brief Summary

The purpose of this survey is to evaluate the long-term safety and efficacy of leuprorelin acetate injection kit 11.25 mg in patients with spinal and bulbar muscular atrophy (SBMA) in the routine clinical setting.

Conditions

Spinal and Bulbar Muscular Atrophy

Outcome Measures

Primary Outcomes (2)

• Percentage of Participants who had One or More Adverse Drug Reactions

  Adverse drug reaction refers to adverse events related to administered drug. Percentage of participants who have the adverse drug reactions that occurred between initiation of treatment with the drug and 1 year after the start of treatment with the drug (or 3 months after the last dose of the drug if the treatment was discontinued within the first four doses) will be reported.

  Up to 1 Year

• Percentage of Participants who had One or More Serious Adverse Events

  Percentage of participants who have the serious adverse events that occurred between initiation of treatment with the drug and 1 year after the start of treatment with the drug (or 3 months after the last dose of the drug if the treatment was discontinued within the first four doses) will be reported.

  Up to 1 Year

Secondary Outcomes (4)

• Percentage of Participants without Death Event

  At final assessment point (up to 8 years)

• Percentage of Participants without Pneumonia Requiring Hospitalization Event

  At final assessment point (up to 8 years)

• Percentage of Participants without Composite Events of Death and Pneumonia Requiring Hospitalization

  At final assessment point (up to 8 years)

• Percentage of Participants without Dysphagia Events

  At final assessment point (up to 8 years)
