Een studie om de veiligheid en werkzaamheid op lange termijn te beoordelen van een subcutane formulering van efgartigimod bij volwassenen met actieve idiopathische inflammatoire myopathie (ALKIVIA+)
Een fase 3, eenarmige, multicenter, open-label uitbreiding van onderzoek ARGX-113-2007 om de veiligheid, verdraagbaarheid en werkzaamheid op lange termijn van Efgartigimod PH20 SC te onderzoeken bij deelnemers van 18 jaar en ouder met actieve idiopathische inflammatoire myopathie
The main purpose of this study is to measure the long-term safety and tolerability of efgartigimod PH20 SC in adult participants with Idiopathic Inflammatory Myopathy (IIM) who previously participated in ARGX-113-2007.
The study consists of a treatment period where participants will receive efgartigimod PH20 SC for up to 51 months. The treatment period will be followed by a treatment-free safety follow-up period of 56 days.

C-GTI comprising the AIS over time
Tijdsspanne: Up to 51 months
|
The Composite Glucocorticoid Toxicity Index (C-GTI) serves as a primary instrument to capture toxicities likely caused by glucocorticoid exposure and enables monitoring of long-term tolerability of glucocorticoids during prolonged use. The Aggregate Improvement Score (AIS) is an analytical scores generated from the weighted C-GTI. The AIS can be used to assess whether a new therapy is effective in reducing glucocorticoid toxicity over time; higher AIS scores are associated with less toxicity. |
Up to 51 months
|
|
C-GTI comprising the CWS over time
Tijdsspanne: Up to 51 months
|
The Composite Glucocorticoid Toxicity Index (C-GTI) serves as a primary instrument to capture toxicities likely caused by glucocorticoid exposure and enables monitoring of long-term tolerability of glucocorticoids during prolonged use. The Cumulative Worsening Score (CWS) is an analytical score generated from the weighted C-GTI. The CWS is designed to assess cumulative glucocorticoid toxicity; higher scores indicate increased steroid toxicity. |
Up to 51 months
|
|
C-GTI comprising the GTI-MD over time
Tijdsspanne: Up to 51 months
|
The Composite Glucocorticoid Toxicity Index (C-GTI) serves as a primary instrument to capture toxicities likely caused by glucocorticoid exposure and enables monitoring of long-term tolerability of glucocorticoids during prolonged use. The Glucocorticoid Toxicity Index-Metabolic Domains (GTI-MD) is an abbreviated GTI version limited to the 4 metabolic domains. A GTI-MD score of 0 indicates a low likelihood of toxicity in the assessed metabolic domains. |
Up to 51 months
|
|
TIS over time
Tijdsspanne: Up to 51 months
|
The total improvement score (TIS) assesses minimal, moderate, and major clinical response, and it is assessed using the ACR/EULAR criteria. The total score varies between 0 and 100, with higher scores indicating greater improvement. |
Up to 51 months
|
|
Proportion of TIS responders (minimal, moderate, major) over time
Tijdsspanne: Up to 51 months
|
The total improvement score (TIS) assesses minimal, moderate, and major clinical response, and it is assessed using the ACR/EULAR criteria. The total score varies between 0 and 100, with higher scores indicating greater improvement |
Up to 51 months
|
|
Individual CSMs of the TIS over time
Tijdsspanne: Up to 51 months
|
The total improvement score (TIS) assesses minimal, moderate, and major clinical response, and it is assessed using the ACR/EULAR criteria. The ACR/EULAR criteria calculate TIS using the 6 core set measure (CSMs): MDGA, PGA, MMT8, HAQ-DI, muscle enzymes, and extramuscular global assessment (assessed by the MDAAT). |
Up to 51 months
|
|
Percentage of participants with clinically inactive disease
Tijdsspanne: Up to 51 months
|
Clinically inactive disease is defined as no evidence of disease activity, based on an Physician Global Assessment of Disease Activity (MDGA) and Extramuscular Global Assessment of the Myositis Disease Activity Assessment Tool (MDAAT) of 0 and normal creatine kinase (CK) values for at least 12 weeks (at week 28 and every 24 weeks thereafter). |
Up to 51 months

|
PGI-S over time
Tijdsspanne: Up to 51 months
|
The Patient Global Impression of Severity (PGI-S) asks participants to rate the severity of their disease symptoms over the past 7 days on a 4-point Likert scale, where scores range from "no symptoms" to "severe." |
Up to 51 months
|
|
CGI-S over time
Tijdsspanne: Up to 51 months
|
The Clinical Global Impression of Severity (CGI-S) asks the physician to rate the severity of the participant's disease on a 4-point Likert scale, where scores range from "no activity" to "severe". |

|
EQ-5D-5L utilities over time
Tijdsspanne: Up to 51 months
|
The EQ-5D-5L questionnaire is a standardized test recognized by many health authorities as a generic measure of health status for clinical and economic appraisal. The descriptive system comprises 5 dimensions, each having 5 levels ranging from "No problem" to "Extreme problem". |
Up to 51 months
|
|
EQ-5D-5L VAS over time
Tijdsspanne: Up to 51 months
|
The EQ-5D-5L questionnaire is a standardized test recognized by many health authorities as a generic measure of health status for clinical and economic appraisal. A visual analog scale (VAS) is included in the EQ-5D-5L, where participants will mark their health status from 0 (the worst health you can imagine) to 100 (the best health you can imagine). |

Up to 51 months
|
|
Proportion of participants with low disease activity over time, while on IMP
