A Phase 2, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group, Dose-range-finding Study to Evaluate the Efficacy and Safety of TF0023 Spray Versus Placebo in Functional Improvement of Patients With Ischemic Strokes

This is a phase 2, multicenter, randomized, double-blind (within dose), placebo controlled, parallel-group, dose-range finding study to evaluate the efficacy and safety of TF0023 spray versus placebo in functional improvement of patients with ischemic strokes under standard of care.

Study Overview

• Status: Suspended
• Conditions: Ischemic Stroke
• Intervention / Treatment: Drug: TF0023

Detailed Description

This randomized, double-blind (within dose), placebo-controlled, parallel group study will be conducted in 2 parts to evaluate the efficacy and safety of TF0023 spray versus placebo in functional improvement in patients with ischemic strokes. Part A will evaluate the safety and efficacy of TF0023 spray in a higher dose . Efficacy will be assessed by the change in modified Rankin Scale (mRS) score from baseline to Week 16. At Week 16, a blinded interim analysis will be performed to determine if TF0023 shows positive results with a higher proportion of patients in the TF0023 group showing a more favorable outcome compared with the placebo group. If the results are positive, then Part B will be initiated to further evaluate safety and efficacy of TF0023 spray as well as to determine the best dosing regimen for the signs and symptoms and functional improvement of patients with ischemic strokes.

Part A In Part A , approximately 200 patients who are stable per the NIHSS will be screened as early as 3 days (72 hours) after the onset of stroke symptoms and approximately 75 will be randomized to active or placebo treatment in a 2:1 ratio (TF0023 [50 patients] and placebo [25 patients]).

Each patient enrolled in Group A will receive study treatment in a double-blind manner for 16 weeks starting between 3 and 60 days after the onset of stroke symptoms (Day 1 of the study). Qualified study personnel will instruct the patients and/or caregivers how to apply the study treatment accurately so that patients or caregivers will administer high dose of either TF0023 or placebo twice daily (approximately every 12 hours).

Patients will return to the study site at Weeks 4, 8, 12, and 16 for efficacy and safety assessments. After the Week 16 assessments have been performed, patients will receive active treatment in an open-label manner starting the next day through the end of the study (EOS) at Week 32. Patients will return to the study site at Week 24 and Week 32 (EOS) for efficacy and safety assessments. An Early Termination visit will occur if the patient is discontinued from the study prematurely. Patients will have a follow-up visit approximately 14 days after the Early Termination visit or the Week 32 (EOS) visit.

An interim analysis will be performed using the data collected through the study up to and including the Week 16 visit. If the analysis of the mRS shows that treatment with TF0023 is positive compared with placebo (mRS score of 0 to 2 indicates functional independence), Part B will start to enroll patients. If the analysis shows that treatment with TF0023 is not positive compared with placebo (mRS score >2), Part B will not enroll any patients.

Part B In Part B, approximately 400 patients who are stable per the NIHSS will be screened as early as 3 days (72 hours) after the onset of stroke symptoms and approximately 150 will be randomized in a 1:1 ratio to Group B (middle dose of TF0023 or placebo twice daily) or Group C (low dose of TF0023 or placebo twice daily ). Patients will be further randomized in a 2:1 ratio within each treatment group: Group B - TF0023 middle dose bid [50 patients] or placebo [25 patients]) and Group C (TF0023 low dose bid [50 patients] or placebo [25 patients]). The study design in Part B will be the same as used in Part A.

Each patient enrolled in either Group B or Group C will receive study treatment in a double blind manner for 16 weeks starting between 3 and 60 days after the onset of stroke symptoms (Day 1 of the study).

Patients will return to the study site at Weeks 4, 8, 12, and 16 for efficacy and safety assessments. After the Week 16 assessments have been performed, patients will receive active treatment in an open-label manner starting the next day through the EOS at Week 32. That is, patients who were receiving active treatment during the double-blinded period will continue to receive active treatment, and patients who were receiving placebo will switch to active treatment for the remaining 16 weeks of the study. Patients will have a follow-up visit approximately 14 days after the Early Termination visit or the Week 32 (EOS) visit.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The primary efficacy endpoint is the change from baseline in the mRS score for all randomized patients at Week 16 in Part A and Part B.	The mRS score measures the patient's functional level of activity and is dichotomized as a favorable outcome (score = 0 - 2) versus unfavorable (score ≥2). The mRS score ranges from 0 (no symptoms) to 6 (death) as follows: 0 = No symptoms at all; = No significant disability despite symptoms; able to carry out all usual duties and activities; = Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance; = Moderate disability requiring some help, but able to walk unassisted; = Moderate severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance.; = Severe disability; bedridden, incontinent, and requiring constant nursing care and attention.; = Dead.	16 weeks of treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Death due to any cause after signing the informed consent form through Week 16 and Week 32.	Death due to any cause through Week 16 and Week 32 for Part A and Part B.	16 and 32 weeks of treatment
Recurrent stroke after signing the informed consent form through Week 16 and Week 32.	To assess the number of patients with recurrent stroke assessed at Week 16 and Week 32 in Part A and Part B. at Week 16 and Week 32 for Part A and Part B.	16 and 32 weeks of treatment
NIHSS score changes after signing the informed consent form through Week 16 and Week 32.	The NIHSS is a serial measure of neurologic deficit and is used to objectively rate the severity of ischemic strokes. The scale is composed of 11 items summarizing a specific ability with scores ranging from 0 to 4. Increasing scores indicate a more severe stroke and has been shown to correlate with the size of the infarction on CT and MRI evaluations.; Level of consciousness including questions and commands; Best gaze; Visual; Facial palsy; Motor arm; Motor leg; Limb ataxia; Sensory; Best language; Dysarthria	0, 16 and 32 weeks of treatment
Barthel Index (BI) changes after signing the informed consent form through Week 16 and Week 32.	To evaluate the effect of TF0023 spray compared with placebo for functional improvement of patients with ischemic strokes measured by improvement of the The BI is an ordinal scale used to measure a patient's performance in 10 individual activities of daily living (ADL). Each item is scored in increments of 5 points (0, 5, 10, or 15) and the individual items are summed to produce a total score between 0 and 100, where 0 is inferior performance and 100 is optimal. The lowest possible score 0 indicates total dependence on others for ADL, and the highest possible score 100 indicates full independence in ADL. A higher score is associated with a greater likelihood of being able to live at home with a degree of independence. A score of ≥95 is considered excellent. The ADL assessed by the BI include: Feeding; Bathing; Grooming; Dressing; Bowels; Bladder; Toilet use; Transfers (bed to chair and back); Mobility (on level surfaces); Stairs	0, 16 and 32 weeks of treatment
Extended Glasgow Outcome Scale (GOS-E) changes after signing the informed consent form through Week 16 and Week 32.	The GOS is a global scale for functional outcome that rates patient status into one of five categories. The GOS-E further details severe disability, moderate disability, and good recovery into lower and higher categories resulting in a total of 8 categories: Dead; Vegetative state; Lower severe disability; Higher severe disability; Lower moderate disability; Higher moderate disability; Lower good recovery; Higher good recovery	0, 16 and 32 weeks of treatment
Shortening the time for performing the timed Trail-Making Tests	The Trail Making Test is a 2-part assessment (Part A and Part B) used to measure executive function in patients who have had experienced a stroke. Successful performance requires a variety of mental abilities including letter and number recognition, mental flexibility, visual scanning, and motor function. Part A requires the patient to connect numbers 1 - 25 in ascending order and Part B requires the patient to connect numbers and letters in an alternating and ascending fashion. Evaluate the effect of TF0023 spray compared with placebo for functional improvement of patients with ischemic strokes measured by shortening the time for performing the timed Trail-Making Tests (Parts A and B) from baseline to Week 16 and Week 32 for study Part A and study Part B.	16 and 32 weeks of treatment
Volume of new fluid attenuation inversion recovery (FLAIR) lesions by DTI-MRI	Magnetic resonance imaging (MRI) is used in diagnosing acute ischemic stroke and can also be used in detecting changes that occur after a stroke. The high resolution of MRI images provides excellent anatomic details and allows measurement of the volume of infarcts accurately and detection of intracranial hemorrhage. Fluid-attenuated inversion recovery (FLAIR) MRI, has important applications in the imaging of stroke patients. FLAIR sequences offer a sensitive method of detecting lesions in the acute, subacute, and chronic stroke situation. Diffusion tensor imaging (DTI) of stroke patients allows volumetric estimations of cerebral infarctions and lesion volumes correlate with clinical outcomes.	16 and 32 weeks of treatment
