NCT07688746

Brief Summary

The researchers are investigating a new treatment for white matter injury, which is a common type of brain injury in premature babies. The drug, clemastine, is experimental. This means that the drug is not approved by the Food and Drug Administration (FDA) for the treatment of white matter injury. The main purpose of this study is to learn whether clemastine is safe to give to infants with white matter injury. The researchers also want to understand how much clemastine gets into an infant's body when the medication is taken by mouth, and how long it stays in the body.

Outcome Measures

Primary Outcomes (1)

  • Number of subjects who experience dose limiting toxicity

    The primary objective is to assess the safety of oral clemastine in preterm neonates with white matter injury (WMI) who have reached at least 35 weeks postmenstrual age (PMA), as measured by the number of subjects who experience dose limiting toxicity (DLT). PMA equals the gestational age (GA) at birth plus chronological age.

    From study drug administration through 30 days after the last dose

Secondary Outcomes (7)

  • Number of patients who experience any adverse events related to the study drug

    From study drug administration through 30 days after the last dose

  • Pharmacokinetics of Clemastine in Preterm Neonates

    From day 1 through day 15

  • Pharmacokinetics of Clemastine in Preterm Neonates

    From day 1 through day 15

  • Pharmacokinetics of Clemastine in Preterm Neonates

    From day 1 through day 15

  • Pharmacokinetics of Clemastine in Preterm Neonates

    From day 1 through day 15

  • +2 more secondary outcomes

Other Outcomes (7)

  • Auditory brainstem response (ABR) at 0-6 months corrected age (CA)

    0-6 months corrected age

  • Brain magnetic resonance imaging (MRI) at 2-3 months corrected age (CA)

    2-3 months corrected age (CA)

  • General Movements Assessment (GMA) at 3-5 months corrected age (CA)

    3-5 months corrected age (CA)

  • +4 more other outcomes

Eligibility Criteria

Age3 Weeks - 20 Weeks
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Born at ≤32 weeks gestational age based on prenatal ultrasound or last menstrual period (LMP).
  • Current age of between 35-41 weeks PMA.
  • Imaging evidence of white matter injury on any scan as defined by either brain MRI or cUS criteria:
  • Brain MRI with Grade Ib WMI or higher based on the Martinez-Biarge et al 2016 criteria.
  • cUS with Grade 3 or higher white matter abnormalities based on Miller et al 2003 criteria.
  • Currently hospitalized in a participating intensive care nursery.

You may not qualify if:

  • Known or suspected metabolic or chromosomal disorder or major congenital anomalies
  • Major intracranial hemorrhage within the last 1 week or intracranial hemorrhage of any age that is not controlled or continuing to cause significant mass effect or midline shift.
  • History of cardiac arrhythmia or current ongoing tachycardia with baseline heart rate \>10% age expected norms.
  • Hypotension requiring ongoing vasopressor or inotropic support.
  • Not able to receive enteral medications.
  • Clinically significant sedation due to critical illness or medications.
  • Concomitant use of any other putative neuroprotective or myelination promoting therapy as determined by the investigator.
  • Serum creatinine, aspartate aminotransferase (AST), or alanine aminotransferase (ALT) \>2x the upper limit of normal for age.
  • Family history of epilepsy due to a confirmed or suspected genetic cause.
  • History of confirmed seizure activity.
  • If ≥36 weeks postmenstrual age, required respiratory support greater than 2L/min, noninvasive positive airway pressure, or mechanical ventilation upon reaching 36 weeks postmenstrual age due to diagnosis of moderate or severe BPD.
  • If less than 36 weeks postmenstrual age, currently requiring respiratory support greater than 2L/min, noninvasive positive airway pressure, or mechanical ventilation, unless respiratory support is being given to promote lung development and not due to clinical need.
  • Major medical conditions, laboratory abnormalities, or concurrent treatments that, in opinion of the investigator, may affect interpretation of study results or patient safety.

Model Details: This is an open-label dose-escalation and dose-expansion study. The Phase I component will employ a conventional "3+3" design with a minimum of three and a maximum of six patients in each of up to three dose levels (Dose level 1, 2, and 3). This is an adaptive, PK-guided trial and a fourth dose will be added if needed to reach the target exposure for the final dose.
