Abstract / Description of output
LACI-1 will assess the tolerability, safety and efficacy, by dose, of ISMN and cilostazol, alone and in combination, in patients with ischaemic lacunar stroke.
A sample of 60 provides 80+% power (significance 0.05) to detect a difference of 35% (90% versus 55%) between those reaching target dose on one versus both drugs.
Methods and design:
LACI-1 is a phase IIa partial factorial, dose-escalation, prospective, randomised, open label, blinded endpoint (PROBE) trial. Participants are randomised to ISMN and/or cilostazol for 11 weeks with dose escalation to target as tolerated in two centres (Edinburgh, Nottingham). At three visits, tolerability, safety, blood pressure, pulse wave velocity and platelet function are assessed, plus magnetic resonance imaging (MRI) to assess cerebrovascular reactivity in a subgroup.
Primary: proportion of patients completing study achieving target maximum dose.
Secondary: symptoms whilst taking medications; safety (haemorrhage, recurrent vascular events, falls); blood pressure, platelet function, arterial stiffness and cerebrovascular reactivity.
This study will inform the design of a larger phase III trial of ISMN and cilostazol in lacunar stroke, whilst providing data on the drugs’ effects on vascular and platelet function.
