Uno studio per valutare la sicurezza e l'efficacia a lungo termine di una formulazione sottocutanea di Efgartigimod negli adulti con miopatia infiammatoria idiopatica attiva (ALKIVIA+)

15 ottobre 2026 aggiornato da: argenx

Un'estensione dello studio ARGX-113-2007 di fase 3, a braccio singolo, multicentrico, in aperto per studiare la sicurezza, la tollerabilità e l'efficacia a lungo termine di Efgartigimod PH20 SC nei partecipanti di età pari o superiore a 18 anni con miopatia infiammatoria idiopatica attiva

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.

Fino a 51 mesi
C-GTI comprising the AIS over time
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Lasso di tempo: 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
Percentage of participants with remission during the study
Lasso di tempo: Up to 51 months

Remission is defined as a clinically inactive disease for at least 24 weeks

Up to 51 months
PGI-S over time
Lasso di tempo: 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
Lasso di tempo: 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".

Up to 51 months
Physical Functioning subscale and Physical Component Summary scores of the SF-36v2 over time
Lasso di tempo: Up to 51 months

The 36-Item Short Form Survey version 2 (SF-36v2) is a 36-item scale constructed to survey health-related quality of life in 8 domains.

Up to 51 months
EQ-5D-5L utilities over time
Lasso di tempo: 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
Lasso di tempo: 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
Incidence of ADA against efgartigimod (serum levels) over time
Lasso di tempo: Up to 53 months

ADA : anti-drug antibodies.

Up to 53 months
Proportion of participants achieving sustained low disease activity while on IMP, over time
Lasso di tempo: Up to 51 months

Sustained low disease activity is defined as a CGI-S score of "mild" or "no activity" and a PGI-S score of "mild" or "no symptoms" for at least 12 weeks.

Up to 51 months
Proportion of participants with low disease activity over time, while on IMP
Lasso di tempo: Up to 51 months

Low disease activity is defined as a CGI-S score of "mild" or "no activity" and a PGI-S score of "mild" or "no symptoms"

Up to 51 months
Proportion of participants with low disease activity who continue dosing every 2 weeks at week 52 and every 24 weeks thereafter
Lasso di tempo: Up to 51 months

Low disease activity is defined as a CGI-S score of "mild" or "no activity" and a PGI-S score of "mild" or "no symptoms"

Up to 51 months
Proportion of participants who have marked worsening during the period of dosing every 2 weeks
Lasso di tempo: Up to 51 months

Marked worsening is defined as a CGI-S score of "moderate" or "severe" and a PGI-S score of "moderate" or "severe"

Up to 51 months
