Description

Summary

This is a Phase 1, multi-center, randomized, double-blind, placebo-controlled, multiple-ascending- dose trial to evaluate the safety, tolerability, immunogenicity, and pharmacokinetics of intravenous PNT001 in hospitalized patients with traumatic brain injury.

Official Title

Phase 1, Randomized, Double-blind, Placebo-controlled, Multiple-ascending-dose Trial to Evaluate the Safety, Tolerability, Immunogenicity, and Pharmacokinetics of Intravenous PNT001 in Hospitalized Patients With Traumatic Brain Injury (TBI)

Details

The Phase 1 study is a double-blind, multiple ascending dose trial evaluating a total of 64 patients across two dose cohort groups. Each cohort will include 32 patients (24 active; 8 placebo) who will be randomized to receive three doses of either PNT001 or placebo. Doses studied will be 1000mg and 4000mg. Patients admitted to the trauma center who meet entrance criteria will receive their first dose of study drug within 24 hours of documented TBI. They will remain in the facility for at least 24 hours after initial dose. Baseline biomarker collection and cognitive assessments will be completed. Study medication will be administered as an IV infusion over 30 minutes (for 1000mg cohort) or 60 minutes (for 4000mg cohort) followed by collection of safety, tolerability, pharmacokinetic, biomarker, imaging, and cognitive data over 12 weeks. Subsequent dosing visits will be at Days 28 and 56. All visits after initial discharge will be on an outpatient basis.

  2. Duration from documented time of TBI event to time of start of initial dose of study drug will not exceed 24 hours.
  3. Signed informed consent by patient, or where applicable, patient's legally authorized representative.
  4. Male and females, 18- 65 years of age at time of screening (State's legal age of majority is minimum age if higher than 18).

  6. Male must agree to use acceptable contraception and refrain from sperm donation during the entire study and for 200 days after dosing has been completed.
  7. Has not participated in a clinical drug trial within 3 months of study start.
  8. Body Mass Index (BMI) of 18.5-35.0 kg/m2 and for the 4000mg dose group only, weight greater than or equal to 44.8 kg.
  9. Vision, hearing, speech, motor function, and comprehension sufficient for compliance with all testing procedures and assessments.

You CAN'T join if...

  1. TBI that does not require hospitalization.
  2. TBI outside 24-hour window.
  3. GCS < 9 within 2 hours of dosing.
  4. History of TBI in past 12 months that resulted in patient seeking medical attention.
  5. Evidence of penetrating head trauma or depressed skull fracture.
  6. Clinical or radiographic evidence of mass effect, midline shift, or intracranial hypertension, requiring craniotomy/craniectomy.
  7. Evidence of symptomatic cervical, thoracic, lumbar spine injury e.g. paresis, radiculopathy, that can be localized to the injury.
  8. Systemic traumatic injury that would preclude participation in study or is expected to result in long-term disability.
  9. Any other acute or chronic medical illness that in the judgement of the study physician results in functional impairment or impairs neuropsychiatric function.
  10. . Any acute intoxication that in the judgement of the study physician results in significant functional impairment or impairs neuropsychiatric function.
  11. . Any history of cancer within 5 years of enrollment with the exception of resected skin basal cell carcinoma.
  12. . Any major surgery requiring general anesthesia within 4 weeks of study drug administration.
  13. . Donation of blood or serum ≥500 mL to a blood bank or in a clinical study (except screening visit) within 3 months of study drug administration.
  14. . Known recent (within 6 months of study drug administration) drug or alcohol abuse as defined in DSM V, Diagnostic Criteria for Drug and Alcohol Abuse.
  15. . Evidence of any clinically significant neurological or psychiatric disorder that could interfere with study assessments as determined by investigator and sponsor.
  16. . Patient has history or currently has schizophrenia, schizoaffective disorder or bipolar disorder, untreated major depression (DSM-V or ICD-10 criteria).
  17. . Significant illness within the prior 30 days.
  18. . Abnormalities in creatinine, hepatic transaminases, or QT that would preclude entry into the study.
