Brief summary

Stroke is the third leading cause of death in Australia. Ischaemic stroke accounts for ~80% of all stroke cases and is caused by a narrowing or obstruction of the blood vessels resulting in oxygen and nutrient deprivation. Conventional post-stroke management involves combining pharmacotherapy and rehabilitative therapies. Nao Xin Qing (NXQ) is a TGA-approved product (AUSTL196297) in Australia. NXQ is a novel herbal formula made from the standardised extract of persimmon leaves. NXQ has been used clinically in China for numerous years in the treatment of apoplexy, coronary heart disease and enhance recovery from ischemic stroke. The aim of this randomised double-blind controlled study is to assess the clinical effectiveness of NXQ for ischaemic stroke patients during rehabilitation phase. This will provide preliminary data whether NXQ can be used as an effective treatment of ischaemic stroke recovery, to prevent recurrence of stroke and improve quality of life of stroke survivors.

Interventions

This study will be conducted as a two-arm randomized, double-blind, placebo controlled clinical trial of 36 weeks, including a 12-week intervention and 26-week follow-up. For a two-arm trial, participants will be randomized after informed consent is obtained, into two parallel treatment groups: a. Intervention group taking NXQ (Active) b. Placebo control group (Placebo) Intervention Active NXQ 0.41g tablet, composition: • Diospyros Kaki leaf extract 50 mg (active component) • Starch • Sucrose

At each appointment, an allocation of medication will be dispensed to participants by research personnel according to the pre-coded container labelling. Participants will be required to return the original containers and any unused medication for monitoring and adherence to the intervention. Any unused medication will then be destroyed locally with approval of the coordinating chief investigator. All delivered and dispensed, unused and returned quantities will be recorded in a medication log.
