A Study to Evaluate the Long-Term Efficacy and Safety of BMN 110 in Patients With Mucopolysaccharidosis IVA (Morquio A Syndrome)

August 28, 2015 updated by: BioMarin Pharmaceutical

A Multicenter, Multinational, Open-Label, Extension Study to Evaluate the Long-Term Efficacy and Safety of BMN 110 in Patients With Mucopolysaccharidosis IVA (Morquio A Syndrome)

This multicenter, open-label extension study is designed to assess long-term efficacy and safety of 2.0 milligrams (mg)/kilogram(kg)/week of BMN 110 in patients diagnosed with Mucopolysaccharidosis IVA (MPS IVA). Patients with MPS IVA, who enrolled in a prior BioMarin sponsored clinical study of BMN 110 (NCT00884949; Study Identification Number MOR-002), were eligible to enroll in this study (except patients who enrolled in NCT01275066; Study Identification Number MOR-004).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Willing and able to provide written, signed informed consent, or in the case of patients under the age of 18 (or 16 years, depending on the region), provide written assent (if required) and written informed consent by a legally authorized representative after the nature of the study has been explained, and prior to any research-related procedures.
  • Sexually active patients must be willing to use an acceptable method of contraception while participating in the study.
  • Females of childbearing potential must have a negative pregnancy test at Baseline and be willing to have additional pregnancy tests during the study.
  • Must have enrolled in a prior BioMarin sponsored clinical study of BMN 110.

Exclusion Criteria:

  • Pregnant or breastfeeding at Baseline or planning to become pregnant (self or partner) at any time during the study.
  • Use of any investigational product (other than BMN 110 in a prior clinical study) or investigational medical device within 30 days prior to Baseline, or requirement for any investigational agent prior to completion of all scheduled study assessments.
  • Concurrent disease or condition, including but not limited to symptomatic cervical spine instability, clinically significant spinal cord compression, or severe cardiac disease that would interfere with study participation or safety as determined by the Investigator.
  • Any condition that, in the view of the Investigator, places the patient at high risk of poor treatment compliance or of not completing the study.
  • Were enrolled in MOR-004 (patients from MOR-004 may be eligible to participate in a separate, appropriately designed, extension study).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Safety Evaluation
Time Frame: Entire Study Period, up to 240 weeks

The primary objective of the study is to evaluate the safety of weekly infusions of BMN 110; the safety variables included Adverse Events (AEs).

The primary outcome measure data is presented in more detail under the Adverse Events section.
Entire Study Period, up to 240 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
