Phase 2 Study of TXA127 in Post-ischemic Stroke Patients

Status Recruiting

Clinical Trial Summary

This is a 50-patient, Phase 2, double-blind, randomized, placebo-controlled, hybrid decentralized study to evaluate the safety and efficacy of daily subcutaneous (SC) injection of TXA127 in post-ischemic stroke patients. Subjects will receive either TXA127 0.5mg/kg or placebo for 12 weeks started 6 to 24 months post ischemic stroke, and they will have a 12 week follow up visit after treatment has ended. The primary efficacy outcome measure is individual patient absolute change from baseline in motor and sensory functions as measured by the Fugl-Meyer Assessment of Upper Extremity (FMA-UE) 12 weeks after start of treatment.

Clinical Trial Description

This is a safety, tolerability, and efficacy study in patients with sensorimotor deficits after confirmed middle cerebral artery ischemic stroke. The study will be double-blinded and placebo-controlled and conducted over a period of approximately 6 months, with treatment starting 6-24 months after stroke. After obtaining informed consent, eligibility will be determined by review of medical history and assessments of patient's condition. To establish a baseline, all assessments will be completed prior to administration of the first dose of study drug. Patients will be randomized (1:1) to receive either subcutaneous (SC) placebo or TXA127 (0.5 mg/kg) injections once daily for 12 weeks. In addition to receiving either the study drug or placebo, patients will be required to undergo physical therapy (PT) or occupational therapy (OT) at least twice a week. Patients will be followed up for 12 weeks after end of treatment. Throughout the study, study visits will be conducted at the medical center and the patient's home. At certain planned study visits, patients will undergo a brief physical examination, and blood will be drawn for safety evaluation and for measuring biomarkers. At the Screening, Week 12, and Week 24 visits, patients will rate their disability and health-related quality of life using the Stroke Impact Scale. In addition, upper and lower extremity motor and sensory function (FMA-UE/LE), and gait velocity (Timed Up and Go) will be evaluated. Patients will be asked to report of any safety events throughout the study and follow up period. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
