Open-Label Extension of Zilucoplan in Subjects With Generalized Myasthenia Gravis (RAISE-XT)

A Phase 3, Multicenter, Open-Label Extension Study of Zilucoplan in Subjects With Generalized Myasthenia Gravis

The RAISE-XT study is an open-label extension study to evaluate the long-term efficacy, safety, and tolerability of zilucoplan in subjects with gMG who have previously participated in a qualifying Ra Pharmaceuticals sponsored zilucoplan study.

A treatment-emergent adverse event is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study medication, whether or not considered related to the study medication.

The MG-ADL profile provides an assessment of MG symptom severity and measures 8 items on a 0-3 scale, with 0 being the least severe. The total sum of the 8 items represents the ADL score. The ADL score can range from 0 (least severe) to 24 (most severe).

The QMG test is a standardized quantitative strength scoring system and measures 13 items on a 0-3 scale, with 0 being the least severe. The total sum of the 13 items represents the QMG score. The QMG score can range from 0 (least severe) to 39 (most severe).

The MGC is a 10-item scale that has been used to measure the clinical status of patients with Myasthenia Gravis (MG) in order to evaluate treatment response. The MGC has 4-point Likerttype Scale response options ranging from 0 to 2, 3, 4, 5, 6 or 9 according to the item (weighted response options). The total score is the sum of all items (range 0-50) where higher scores indicate more severe impairment due to the disease.

The MG-QOL15r is a 15-item survey that was designed to assess quality of life in patients with MG. The MG-QoL has 3-point Likert Scale response options ranging from 0 to 2. The MGQoL15r score can range from 0 to 30, where higher scores indicate more severe impact of the disease on aspects of the patient's life.

Inclusion Criteria: Completion of a qualifying zilucoplan study Exclusion Criteria: With the exception of a prior zilucoplan trial, participation in another concurrent clinical trial involving an experimental therapeutic intervention (participation in observational studies and/or registry studies is permitted)

Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
