Switch from intravenous to subcutaneous immunoglobulin in patients with myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP): A single-arm, open-label, prospective pilot study to determine efficacy, treatment satisfaction, health care resource utilization and tolerability

The aim of this study will investigate efficacy, treatment satisfaction, health care resource utilization and tolerability of SCIg in MG and CIDP patients previously treated with IVIg. . The data gathered during the study may also be useful for medical professionals and researchers in the future.

A Study of Nipocalimab Administered to Adults With Generalized Myasthenia Gravis

Myasthenia gravis (MG) is a rare, heterogeneous, neuromuscular disease characterized by fluctuating, fatigable muscle weakness. MG is caused by pathogenic autoantibodies that impair cholinergic transmission in the postsynaptic membrane at the neuromuscular junction and impair or prevent muscle contraction.

Nipocalimab (also referred to as JNJ-80202135 or M281) is a fully human, aglycosylated immunoglobulin (Ig)G1 monoclonal antibody (mAb) designed to selectively bind, saturate, and block the IgG binding site on the endogenous neonatal Fc receptor (FcRn).

This study will consist of a screening phase (up to 4 weeks), treatment phase (a 24-week double-blind placebo-controlled phase, and an open-label extension [OLE] phase [up to 2 years]) and a follow-up safety visit (up to 8 weeks after last infusion of study intervention). Efficacy evaluations will include assessments such as Myasthenia Gravis – Activities of Daily Living (MG-ADL) score.

The overall duration of study will be up to 4 years and 8 months.

A Phase III, Randomized, Double-Blind, Placebo-Controlled, Multicenter Study To Evaluate Efficacy, Safety, Pharmacokinetics, And Pharmacodynamics Of Satralizumab In Patients With Generalized Myasthenia Gravis 

The purpose of this study is to compare the effects, good or bad, of subcutaneous (under the skin) injections of satralizumab in combination with current treatment (background therapy) in patients with gMG. 

This study will also collect more data on the long-term safety and efficacy of satralizumab and continue providing you with satralizumab treatment during an open label extension period. 

For this study, 240 male and female participants, including 20 adolescents, will be recruited at 120 sites. The rest of the participants will be aged 18+ years. The Montreal Neurological Institute-Hospital will only recruit adult patients aged 18 years and older.

Safety and Efficacy of Pitolisant on Excessive Daytime Sleepiness and Other Non-Muscular Symptoms in Patients With Myotonic Dystrophy Type 1

The primary objective of this study is to evaluate the safety and efficacy of pitolisant compared with placebo in treating excessive daytime sleepiness (EDS) in patients with Myotonic Dystrophy Type 1 ages 18 to 65 years.

The secondary objectives of this study are to assess the impact of pitolisant on fatigue, cognitive function and the burden of disease along with assessing the long-term safety and effectiveness of pitolisant in patients with Myotonic Dystrophy Type 1 ages 18 to 65 years.

A Phase 2, Randomized, Double-Blind, Placebo-Controlled, 48-Week, Parallel-Group Study of the Efficacy and Safety of Losmapimod in Treating Subjects with Facioscapulohumeral Muscular Dystrophy (FSHD) with Open-Label Extension (OLE)

The purpose of the 48 week placebo-controlled treatment period of this study is is to determine whether losmapimod may slow down or stop the progression of the disease in individuals with FSHD by preventing or decreasing DUX4 expression in skeletal muscle and other affected organs. This study will also evaluate how you feel when you are taking the study drug and assess how you think the study drug may be affecting the progression of your disease.

A Phase 3 Global, Randomized, Open-label Study to Evaluate the Efficacy and Safety of ALN-TTRSC02 in Patients With Hereditary Transthyretin Amyloidosis (hATTR Amyloidosis)

The purpose of this study is to evaluate the efficacy and safety of vutrisiran (ALN-TTRSC02) in patients with hereditary transthyretin amyloidosis (hATTR amyloidosis). Participants will receive vutrisiran or the reference comparator patisiran during the Treatment Period. The Treatment Period is followed by a Treatment Extension Period during which all participants in the patisiran group will switch to vutrisiran. This study will use the placebo arm of the APOLLO study (NCT01960348) as an external comparator for the primary and most other efficacy endpoints.

A phase 3, randomized, double-blind, placebo-controlled study evaluating efficacy and safety of rozanolixizumab in adult patients with generalized myasthenia gravis

From clinicaltrials.gov:

The purpose of the MycarinGstudy is to demonstrate the clinical efficacy and to assess safety and tolerability of rozanolixizumab in patients with generalized myasthenia gravis (MG).

A Phase III trial of pamrevlumab or placebo in combination with systemic corticosteroids in subjects with non-ambulatory Duchenne Muscular Dystrophy

From clinicaltrials.gov:

This is a global, randomized, double-blind trial of pamrevlumab or placebo in combination with systemic corticosteroids in subjects with non-ambulatory Duchenne muscular dystrophy, aged 12 years and older. Approximately 90 male subjects will be randomized at a 1:1 ratio to Arm A (pamrevlumab + systemic corticosteroid) or Arm B (placebo+ systemic corticosteroid), respectively.

Subjects will be randomized in a 1:1 ratio to one of the two study treatment arms; pamrevlumab or placebo in combination with systemic steroids.

This trial has three study periods:

• Screening period: Up to 4 weeks
• Treatment period: 52 weeks
• Safety Follow-up period/final assessment: 4 weeks (Week 56 (+/-3 days))

The purpose of this study is to investigate how effective PXT3003 is when compared to a placebo on the disease progression and symptoms of CMT1A. PXT3003 consists of a combination of very low doses of 3 currently approved pharmaceutical ingredients: (RS)-baclofen, naltrexone HCl, and D-sorbitol, which are thought to act in different ways to treat CMT1A. 

The placebo used in this study looks exactly like PXT3003 but it does not contain any active medication. Placebos are sometimes called sugar pills, dummy treatments, or shams. We are using a placebo to compare with PXT3003, and to ensure that the changes you report in your health, good or bad, are not only due to chance.  In this information and consent form, the use of “study drug” refers either to PXT3003 or to the placebo. 

The study also aims to assess the safety and tolerability (whether side effects of a medication can be handled by patients) of PXT3003. 

For this study, 350 male and female participants will be recruited at 50 sites globally. The participants will be aged between 16 to 65 years. Only adults 18 years and older will be recruited at the Montreal Neurological Institute-Hospital.
