TITACIPPI: Tirofiban Plus Intravenous Thrombolysis in Acute Anterior Choroidal Infarction or Paramedian Pontine Infarction
Study Details
Study Description
Brief Summary
TITACIPPI (Tirofiban with Intravenous Thrombolysis in Acute Anterior Choroidal Infarction [ACI] and Paramedian Pontine Infarction [IPP]) study aimed to evaluate the efficacy and safety of simultaneous infusion of tirofiban with intravenous thrombolysis (IVT + tirofiban group) compared to IVT alone (IVT alone group) in patients with ACI or PPI. TITACIPPI study is a retrospective, single-center observational study conducted from March 01, 2014, to December 31, 2022.

Detailed Description
ACI and PPI are frequently associated with clinical fluctuations, characterized by recurrent transient more or less regressive stereotyped episodes of focal motor deficits affecting the face, arm, and leg, and finally with a risk of lasting neurological worsening that can lead to definite residual neurological disability. These ischemic strokes (ACI and PPI) are not very sensitive to IVT, thus 26% to 48% will experience neurological aggravation despite the administration of this treatment. Studies in Asia have shown a possible clinical benefit of simultaneous infusion of tirofiban with IVT in patients with ischemic stroke of atheromatous or microatheromatous origin without additional bleeding risk. To date, no studies have tested the efficacy of simultaneous infusion of tirofiban and IVT in the well-defined subgroup of ACI and PPI and a non-Asian population.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Intravenous thrombolysis (IVT) group of patients treated with IVT alone |
Procedure: IVT with tenecteplase or alteplase
Patients received intravenous tenecteplase 0.25mg/kg (maximum dose: 25mg), administered as a bolus over 5 to 10 seconds or intravenous alteplase 0.9 mg/kg (maximum dose: 90mg), 10% as bolus and the remainder as continuous perfusion over 1 hour.

Tirofiban + IVT groups of patients treated with simultaneous infusion of tirofiban and IVT |
Procedure: Intervention Name : Tirofiban and IVT with tenecteplase or alteplase
IVT with tenecteplase or alteplase with continuous infusion of tirofiban 0.4µg/kg/min continued for 24 to 48 hours.

Outcome Measures
Primary Outcome Measures
- Volume of the ischemic lesion [at 24 hours]
Evolution of the volume of the ischemic lesion in diffusion-weighted imaging between initial MRI and post-therapy MRI
Secondary Outcome Measures
- NIHSS [at day 7]
NIHSS (from 0=favorable to 42=unfavorable)
- Modified Rankin Scale (mRS) [at 3 months]
Proportion of the patients with mRS 0-2
- Secondary neurological deterioration [at 72 hours]
Rate of secondary neurological deterioration (fluctuations or neurological progression defined as an increase of at least 1 point in NIHSS).
- Cerebral hemorrhages [at 24 hours]
Rates of cerebral hemorrhages defined according to the Heidelberg Bleeding Classification
- Systemic bleedings [at 24 hours]
Rate of significant systemic bleeding (i.e., requiring specific treatment).
