E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluate the safety, tolerability, and immunogenicity of long-term treatment with intravenous (IV) ATYR1940 in adult patients with facioscapulohumeral muscular dystrophy (FSHD) previously enrolled in clinical study ATYR1940-C-002 |
|
E.2.2 | Secondary objectives of the trial |
• Evaluate the effects of long-term ATYR1940 treatment on clinically relevant measures of muscle strength and function, including: Quantitative Muscle Testing (QMT) and Manual muscle testing (MMT), as determined by the Investigator • Evaluate the effects of long-term ATYR1940 treatment on patient-reported quality of life (QoL) • Evaluate the effects of long-term ATYR1940 treatment on muscle disease burden, based on skeletal muscle magnetic resonance imaging (MRI) • Explore biological and pharmacodynamic (PD) changes in the inflammatory immune state in peripheral blood • Determine the long-term systemic exposure to ATYR1940 through pharmacokinetic (PK) sampling |

In the Investigator’s opinion, patient has shown acceptable compliance with study drug and the study procedures in the parent study and is willing and able to comply with all procedures in the current study. 4. Is, in the opinion of the Investigator and Sponsor, a suitable candidate for continued study drug treatment. 5. Provided written informed consent after the nature of the study has been explained and prior to the performance of any research-related procedures. |

E.4 | Principal exclusion criteria |
1. At any time during participation in the parent study, met a study drug discontinuation criterion, including, but not limited to: a. Jo-1 Ab levels ≥1.5 U/mL. b. Clinical evidence of a generalized infusion-related reaction (IRR). c. Clinical evidence of a National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) (version 4.03) ≥Grade 2, study-drug-related SAE. d. Pregnancy. e. Progression of disease that, in the opinion of the Investigator, precluded further participation in the study. f. Withdrawal of consent. g. Other findings that, at the discretion of the Investigator and/or Sponsor, indicated that study drug administration should be discontinued. 2. Is expected to require treatment with curcumin or systemic albuterol (intermittent inhaled albuterol is permissible) during study participation; or use of a product that putatively enhances muscle growth (e.g., insulin-like growth factor, growth hormone) or activity (e.g., Coenzyme Q, Coenzyme A, creatine, L-carnitine) on a chronic basis; or statin treatment initiation or significant adjustment to statin regimen (stable, chronic statin use is permissible). 3. Planned to receive any vaccination during study participation. 4. Abnormal baseline findings, medical condition(s), or laboratory findings that, in the Investigator’s opinion, might jeopardize the patient's safety or decrease the chance of obtaining satisfactory data needed to achieve the objectives of the study. 5. Evidence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematological, metabolic, dermatological, or gastrointestinal disease, or has a condition that requires immediate surgical intervention or other treatment or may not allow safe participation. 6. If female and of childbearing potential (premenopausal and not surgically sterile), has a positive pregnancy test at entry or is unwilling to use contraception from the time of entry through the 1-month Follow-up visit. Acceptable methods of birth control include abstinence, barrier methods, hormones, or intra-uterine device. 7. If male, is unwilling to use a condom plus spermicide during sexual intercourse from the time of entry through the 1 month Follow-up visit" |
