JRCT ID: jRCTs031180038

Registered date:12/11/2018

Basic Information

• Recruitment status: Not Recruiting
• Health condition(s) or Problem(s) studied: muscular dystrophy
• Date of first enrollment: 18/12/2018
• Target sample size: 20
• Study type: Interventional

Intervention(s)

Tranilast 300 mg / day is administered three times per minute.
Treatment for 28 weeks (in principle, outpatient administration). As of the 28th week, reconfirmation of consent regarding continuation of administration is confirmed, and if confirmation is obtained, further treatment for 116 weeks is carried out.

Outcome(s)

• Primary Outcome: The change in BNP before the start of administration (using the average of values in the pre-treatment observation period and at the start of administration) to 24 weeks (using the average of values at 20 weeks, 24 weeks and 28 weeks)

Secondary Outcome

1) Cardiac events (change of oral medicine for cardiac failure due to cardiac function exacerbation (ACEI/ARB, Beta blocker, digitalis, diuretic, aldosterone antagonist, cardiotonic agent or antiarrhythmic agent), administration of intravenous drugs (cardiotonic agents, diuretics or antiarrhythmic agent), hospitalization due to heart failure or prolongation of hospitalization)
2) All deaths
3) Left ventricula fractional shortening (FS)
4) Human atrial natriuretic peptide (hANP), cardiac troponin T (cTnT)
5) The expression of transient receptor potential cation channel, subfamily V, member 2 (TRPV2) expression on cytoplasminc membrane of isolated peripheral blood mononuclear cells (PBMCs)
6) Hand finger muscle strength (pinch strength), creatine kinase (CK)
7) Muscular dystrophy quality of life-60 (MDQOL-60), The short form (12) health survey (SF-12)
8) Adverse events

Key inclusion & exclusion criteria

• Age minimum: >= 13age old
• Age maximum: Not applicable
• Gender: Both

Include criteria

1) MD patients aged 13 or more
2) With high value in BNP (100 pg/mL or more)
3) Those introduced with standard myocardium protective drugs (angiotensin converting enzyme inhibitor (ACEI)/angiotensin type II receptor blocker (ARB) and/or beta blocker) who meets both of the following:
taking maintenance doses at the time of consent;
whose dosage regimen and doses are fixed from 2 weeks before the start of administration until the start of administration.
4) To whom intrinsic administration of capsule, fine granules or dry syrup is possible, or who can be reliably administered tranilast by tube
5) Provided written consent by their free will / the representative

Exclude criteria

1) Acute stage heart failure condition (using cardiotonic, diuretic, antiarrhythmic drug intravenously)
2) From 2 weeks before the start of administration to the start of administration Directions of digitalis, diuretic, aldosterone antagonist, cardiotonic agent, antiarrhythmic drug are not fixed
3) With a lethal arrhythmia including ventricular premature contraction of more than four (short run)), excluding those with transplanted implantable defibrillators
4) With serious renal dysfunction (estimated glomerular filtration ratio (eGFR) using cystatin C of less than 30 mL/min/1.73 m2)
Male: eGFR = (104 ^ Cystatin C-1.019^ 0.996age (years)) - 8
Female: eGFR = (104 ^ Cystatin C-1.019 ^ 0.996age (years) ^ 0.929) - 8
For those aged 18 or less, cyctain C of 2.5 mg/L or more is used.
5) With severe liver function disorder (T.

6) Marked white blood cell (WBC) decrease (less than 3000/mm^3), platelet (Plt) decrease (less than 80,000/mm^3)
7) Having a history of hypersensitivity to tranilast
