About this study
Official title: An Open-Label Extension Study to Evaluate the Long-Term Safety, Tolerability, and Biological Activity of ATYR1940 in Patients With Limb Girdle and Facioscapulohumeral Muscular Dystrophy
ATYR1940-C-006 is a multi-national, multicenter study being conducted at centers in the United States (US) and Europe who participated in Study ATYR1940-C-003 (Stage 1 only) or Study ATYR1940-C-004 (that is, the parent studies).
Read the detailed description
Study ATYR1940-C-006 is a multi-national, multi-center, open-label extension study designed to evaluate the long-term safety, effects on muscle, and pharmacodynamics of ATYR1940 in participants with Limb-girdle muscular dystrophy (LGMD) or FSHD previously treated in the Study ATYR1940-C-003 (Stage 1 only) or Study ATYR1940-C-004 that is, the parent studies). This study will be conducted at the same study centers at which participants were enrolled in the parent studies.
Participants who completed the treatment period in the parent study and, in the Investigator's opinion, demonstrated acceptable tolerability of ATYR1940, are considered by the Investigator to be compliant with ATYR1940 and the study procedures, and do not meet any criterion for ATYR1940 discontinuation are eligible for participation in the current study, contingent upon Investigator and participant agreement to continue ATYR1940 treatment.
For the first 12 weeks in this extension study, participants will receive ATYR1940 at the highest tolerated dose received in the parent study; no dose adjustments are allowed during this 12-week period. After 12 weeks, if the participant is demonstrating good tolerability, the ATYR1940 dose may be increased on a participant-specific basis at the Investigator's discretion, in consultation with the Sponsor and Medical Monitor. ATYR1940 dose increases to >3.0 mg/kg are not permissible.
All participants will receive ATYR1940 on a weekly basis in this study, regardless of the frequency of dosing in the parent study. ATYR1940 will be administered via intravenous (IV) infusion over 90 minutes. If medically indicated, the infusion duration and volume may be adjusted at the Investigator's discretion in consultation with the Medical Monitor and Sponsor.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
TEAEs were defined as adverse events (AEs) with an onset following administration of the first dose of study drug. AEs were defined as any untoward medical occurrence in a participant administered study drug and that does not necessarily have a causal relationship with the study drug. Worsening of a pre-existing medical condition should have been considered an AE if there was either an increase in severity, frequency, or duration of the condition or an association with significantly worse outcomes. SAEs were defined as any AE that, in the view of either the Investigator or Sponsor, resulted in any of the following outcomes as fatal, life-threatening, required in-participant hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, an important medical event. A summary of all SAEs and Other AEs (nonserious) regardless of causality is located in 'Reported Adverse Events' Section.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With Positive Anti-Drug Antibodies (ADA)
Summarized titers are reported below.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With a Jo-1 Antibody (Ab) Test Result ≥1.5 Units/Milliliter (U/mL)
Participants with Jo-1 Ab levels ≥1.5 U/mL were to be discontinued from dosing of the study drug.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With a Clinical Laboratory Abnormality Leading to an AE
Laboratory parameters included hematology (hematocrit, hemoglobin, red blood cell count, white blood cell count neutrophils, lymphocytes, monocytes, eosinophils, basophils, and platelet count); serum chemistries (blood urea nitrogen, creatinine, total bilirubin, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, total protein, sodium, potassium, bicarbonate, calcium, chloride, magnesium, inorganic phosphate, creatine kinase, lactate dehydrogenase, C-reactive protein, troponin, myoglobin, insulin-like growth factor 1, and cholesterol [nonfasting]); and urinalysis (color, pH, specific gravity, protein, glucose, ketones, and blood). Clinically significant laboratory abnormalities were based upon Investigator's discretion. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With a Clinically Significant Pulmonary Function Event Resulting in a TEAE
Pulmonary evaluations included pulmonary function tests and pulse oximetry. Clinically significant changes were to be reported as adverse events. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With a Clinically Significant Electrocardiogram (ECG) Abnormality Leading to a TEAE
ECG parameters that were evaluated included heart rate and PR, QR, and QT intervals. A clinically significant ECG abnormality was based upon the Investigator's discretion. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
Measured: Up to End of Study (up to approximately Week 39)
Number of Participants With Vital Sign Abnormality Resulting in a TEAE
The vital sign parameters that were evaluated included heart rate, systolic and diastolic blood pressure, and respiration rate as well as temperature. A summary of all Serious Adverse Events and Other Adverse Events (nonserious) regardless of causality is located in the 'Reported Adverse Events' Section.
Measured: Up to End of Study (up to approximately Week 39)
Change From Baseline in Manual Muscle Testing (MMT) Score at Week 12
MMT (muscle strength) will be graded using a modified Medical Research Council scale. Scores were converted to 13-point scale (range from 0 [on contraction palpable] to 12 [normal strength]). An overall total score was calculated by summing all scores for a total possible score of 336. Decreased muscle strength was indicated by a decreased score. An overall total score was calculated as long as 24 of the 28 individual scores were non-missing.
Measured: Baseline, Week 12

A Phase 1/2 study testing ATYR1940 in people with Facioscapulohumeral Muscular Dystrophy and Limb Girdle Muscular Dystrophy, run by aTyr Pharma, Inc. at 5 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United States, Denmark, Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 22 Dec 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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 Participants With Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) (time frame: Up to End of Study (up to approximately Week 39)). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Dec 2023.
