Development of ADCT involved literature review as well as interviews with patients and physicians, and was funded by Sanofi and Regeneron.

The ADCT gives a measure of how controlled your patient’s eczema is. Use these 6 concise questions to evaluate all dimensions of atopic dermatitis control.

Atopic dermatitis, a type of eczema, may be affecting your patient’s life in more ways than you know.

Nexviadyme®▼
(avalglucosidase alfa) evidence

<h2>Explore Nexviadyme® trials</h2>

<h2>NEO1 (Phase 1)1</h2>
A multicentre, multinational, open-label, ascending dose study of Nexviadyme in ERT-experienced and -naïve patients with LOPD.

Outcomes

Key inclusion criteria

<h2>NEO-EXT (Phase 2)2</h2>
A multicentre, multinational, open-label study of Nexviadyme in ERT-experienced and -naïve patients with LOPD.

Key inclusion criteria

<h2>NEO1 (N=14) ERT-experienced5</h2>
Long-term treatment effect of Nexviadyme on FVC and 6MWT has been shown for up to 8 years in an uncontrolled open-label study in patients with LOPD (NEO1/NEO-EXT).5&nbsp;Each line represents an individual patient.

Adapted from Byrne BJ, et al. 2024.5&nbsp;

Adapted from Byrne BJ, et al. 2024.5&nbsp;

<h2>NEO1 (N=10) ERT-naïve5</h2>
Long-term treatment effect of Nexviadyme on FVC and 6MWT has been shown for up to 8 years in an uncontrolled open-label study in patients with LOPD (NEO1/NEO-EXT).5&nbsp;Each line represents an individual patient.

Adapted from Byrne BJ, et al. 2024.5

<h2>COMET trial (Phase 3)3</h2>
A multicentre, multinational, randomised, double-blinded study to compare the efficacy and safety of bi-weekly infusions of Nexviadyme and Myozyme in patients with LOPD.

*Screening phase up to 14 days, may be extended to up to 8 weeks in pre-specified situations&nbsp; 
 †Randomization 1:1 ratio with stratification factors based on Baseline forced vital capacity, sex, age, and country (Japan or ex-Japan)&nbsp; 
 ‡Study drug infusion, safety assessments, and efficacy evaluations&nbsp; 
 §All participants regardless of prior randomization

<h2>FVC (% predicted), primary endpoint6</h2>
LS mean improvement of 1.40% with Nexviadyme and 1.18% in switch arm participants at week 145 vs baseline (statistical significance not reported).6

Adapted from Kishnani PS, et al. 2023.6 
 *1 participant’s FVC % predicted value at Week 97 was excluded due to a physiologically implausible change between Weeks 73 &amp; 97 and 97 &amp; 121.

<h2>6MWT, secondary endpoint6</h2>
LS mean improvement in 6MWT of&nbsp; 20.65 m with Nexviadyme and 0.29 m in switch arm participants at week 145 vs baseline (statistical significance not reported).6

Adapted from Kishnani PS, et al. 2023.6

Baseline chemographics and characteristics3

Respiratory muscle strength data (secondary endpoints)

Strength and motor function data (secondary endpoints)

HRQoL data (secondary endpoints)

Hex4 data (exploratory pharmacodynamic marker)

<h2>Mini-COMET trial4</h2>
Of 22 included patients with IOPD (1 year of age of older, declining or with sub-optimal response on Myozyme), 16 received Nexviadyme and showed improvement or stabilisation based on secondary outcome measures of preliminary efficacy. The primary outcome measure of Mini-COMET was safety.
This was shown in Mini-COMET across cardiac function, motor function and mobility.8 
 &nbsp;

Patients showed stabilisation or improvement in the mobility domain of the Pompe-PEDI.8

Adapted fron Kronn D, et al. 2024.8 
 Patients are represented by separate lines, with the first dot representing the age at inclusion in the trial and last dot at conclusion for this trial period.
The Pompe-PEDI is based on caregiver reports.

<h2>Safety</h2>
In the COMET trial, there were fewer treatment-related SAEs and IARs with Nexviadyme than with Myozyme. During the 49-week primary analysis period, no patients withdrew from the Nexviadyme arm.3

Paediatric population (patients 6 months of age and younger)

<h2>Contraindications</h2>
Life-threatening hypersensitivity to the active substance or to any of the excipients listed in the SmPC.
<h2>Precautions and Warnings</h2>
Hypersensitivity reactions (including anaphylaxis)
Hypersensitivity reactions, including anaphylaxis, have been reported in Nexviadyme-treated patients. Appropriate medical support measures, including cardiopulmonary resuscitation equipment especially for patients with cardiac hypertrophy and patients with significantly compromised respiratory function, should be readily available when Nexviadyme is administered. If severe hypersensitivity or anaphylaxis occur, Nexviadyme should be discontinued immediately, and appropriate medical treatment should be initiated. The risks and benefits of re-administering Nexviadyme following anaphylaxis or severe hypersensitivity reaction should be considered.
IARs
In clinical studies, IARs were reported to occur at any time during and/or within a few hours after the infusion of Nexviadyme and were more likely with higher infusion rates. Patients with an acute underlying illness at the time of Nexviadyme infusion appear to be at greater risk for IARs. Patients with advanced Pompe disease may have compromised cardiac and respiratory function, which may predispose them to a higher risk of severe complications from IARs. If severe IARs occur, immediate discontinuation of the administration of Nexviadyme should be considered and appropriate medical treatment should be initiated. The benefits and risks of readministering Nexviadyme following severe IARs should be considered.
Immunogenicity
Treatment emergent ADA were reported in both treatment naïve and treatment experienced patients. Adverse-event-driven immunologic testing, including IgG and IgE ADA, may be considered for patients who have risk for allergic reaction or previous anaphylactic reaction to alglucosidase alfa.
Risk of acute cardiorespiratory failure
Caution should be exercised when administering Nexviadyme to patients susceptible to fluid volume overload or patients with acute underlying respiratory illness or compromised cardiac and/or respiratory function for whom fluid restriction is indicated. These patients may be at risk of serious exacerbation of their cardiac or respiratory status during infusion. Appropriate medical support and monitoring measures should be readily available during Nexviadyme infusion.
Cardiac arrhythmia and sudden death during general anaesthesia for central venous catheter placement
Cardiac arrhythmia, including ventricular fibrillation, ventricular tachycardia, and bradycardia, resulting in cardiac arrest or death, or requiring cardiac resuscitation or defibrillation, have been associated with the use of general anaesthesia in IOPD patients with cardiac hypertrophy.
Interactions
No interaction studies have been performed. Because it is a recombinant human protein, avalglucosidase alfa is an unlikely candidate for cytochrome P450 mediated drug-drug interactions.
Fertility and Lactation
There are no available data on the use of Nexviadyme in pregnant women. The potential risk for humans is unknown. Nexviadyme should be used during pregnancy only if the potential benefits to the mother outweigh the potential risks, including those to the foetus.&nbsp;
Breast-feeding
There are no available data on the presence of Nexviadyme in human milk or the effects of Nexviadyme on milk production or the breastfed infant.

<h2>Adverse reactions</h2>
