简要总结
The purpose of the study is to evaluate the pharmacokinetics (PK) of mirabegron oral suspension after single dose administration in children with neurogenic detrusor overactivity (NDO) or overactive bladder (OAB).
This study will also evaluate the safety and tolerability as well as the acceptability and palatability of mirabegron oral suspension after single dose administration in children with NDO or OAB.

- •Idiopathic OAB
- •Subject's weight/height:
- •Subject must have a body weight of ≥ 15.0 kg
- •For NDO: subject is not suffering from malnutrition or is not grossly overweight, in the opinion of the Investigator
- •For OAB: subject's weight and height are within the normal percentiles (3rd to 97th percentile) according to Centers for Disease Control and Prevention (CDC) growth charts.
- •Subject is able to swallow the study medication in accordance with the protocol.
- •Subject and subject's parent(s)/legal guardian agree that the subject will not participate in another interventional study while on treatment.
- •Subject and subject's parent(s)/legal guardian are willing and able to comply with the study requirements and with the concomitant medication restrictions.
- •Female subject must:
- •Be of non-childbearing potential: Clearly pre-menarchal or in the judgment of the Investigator is pre-menarchal.
- •Or the following inclusion criteria are to be followed, if applicable (rare cases): Female subject that reached puberty must: Agree not to try to become pregnant during the study and for 28 days after the final study drug administration, And have a negative urine pregnancy test predose Day 1, And, if heterosexually active agree to consistently use 2 forms of highly effective form of birth control starting at screening and throughout the study period and for28 days after the final study drug administration.
排除标准
- •Subject has a known history of QTc prolongation or risk of QT prolongation (e.g. hypokalemia, family history of Long QT Syndrome) and/or QTcB of > 460 ms.
- •Subject has a (mean) resting pulse rate > 99th percentile [Fleming et al, 2011].
- •Subject has any clinically significant ECG (electrocardiogram) abnormality.
- •Subject has established hypertension and a systolic or diastolic blood pressure greater than the 99th percentile of the normal range determined by sex, age and height, plus 5mmHg [NIH 2005].
- •Subject has any clinically significant or unstable medical condition or disorder which, in the opinion of the Investigator, precludes the subject from participating in the study.
- •Subject has current, untreated constipation (or fecal impaction for NDO subjects). If the constipation is being consistently treated for the last month, the subject can be included.
- •Subject has been administered intradetrusor botulinum toxin injections; except if given > 4 months prior to screening and symptoms reappeared comparable to those before botulinum toxin injections.
- •Subject has aspartate aminotransferase (AST) or alanine aminotransferase (ALT) greater than or equal to 2 times the ULN or total bilirubin greater than or equal to 1.5 times the ULN.

- •Any anticholinergic/antimuscarinic drugs within 5 half-lives prior to planned Reference Day (Day -4 to Day -1).
- •Any drugs that are sensitive CYP2D6 substrates with a narrow therapeutic index (such as thioridazine, flecainide, propafenone, imipramine, desipramine) and sensitive P-gp substrates (such as digoxin, dabigatran) within 5 half-lives prior to the planned Reference Day (Day -4 to Day -1).
- •Any moderate or strong cytochrome CYP3A4/5 or P-gp inhibitors or inducers including natural and herbal remedies (such as itraconazole, rifampicin, phenytoin, carbamazepine, St. John's Wort, grapefruit, Seville orange) within 4 weeks (inducers only) or 5 half-lives (inhibitors only) prior to the planned Reference Day (Day -4 to Day -1).
- •Subject has participated in another clinical trial and/or has taken an investigational drug within 30 days (or 5 half-lives of the investigational drug, whichever is longer) prior to the planned Reference Day (Day -4 to Day -1).
- •Subject's parent(s)/legal guardian is an employee of the Astellas Group, any Contract Research Organization (CRO) involved, or the Investigator site executing the study.
