Oxysterols for Treatment of Perinatal Brain Injury: A First-In-Class Therapy to Prevent Cerebral Palsy in Premature Infants

A Translational Science Benefits Model Case Study

Project in a Nutshell

Premature infants are at higher risk for brain injuries that can cause lifelong impairments, such as cerebral palsy. This research is developing the first treatment to reverse the damage of these brain injuries, using a molecule found in human breast milk.

Significance of the Project

Diffuse white matter injury is the most common brain injury leading to poor neurologic outcomes in survivors of premature birth. The clinical outcomes are diverse depending on severity and its precise location but may include motor disabilities such as cerebral palsy (CP), which is the most common motor disability in childhood.

Population based studies have estimated that~3 per 1,000 children in the United States are affected and this number is higher in developing countries. The greatest risk factor for the development of CP is premature birth, with an inverse relationship between CP risk and gestational age and birth weight.

Per the CDC, CP hasbeen reported in upto 10% of survivors of premature birth. The economic impact of this injury is high with lifetime costs of care for one child with CP estimated at 1.5 million U.S. dollars. Other outcomes of neonatal WMI include permanent cognitive and/or neurosensory impairment.

There are no treatment options for infants with this injury, only supportive care. Therefore, the development of an effective therapy would constitute a major medical breakthrough in this underserved patient population.

Summary of the Project

The goal of this work is to develop anintravenous formulation of an oxysterol (TT-20), which was found in human breast milk, for the treatment of white matter injury (WMI) in preterm infants to preclude CP.

TT-20 is a small molecule that reverses WMI and motor abnormalities in preclinical animal models. Unlike current palliative care options, TT-20 is a first-in-class remyelination treatment that can preclude CP and reduce lifetime costs.

WMI results from the loss of preoligodendrocytes subsequent to inflammation or hypoxic injury experienced by premature infants in the NICU. The loss of these myelinating precursors results in significant and permanent hypomyelination and associated clinical deficits.

Dr. Benner and his team have identified multiple oxysterols in human maternal breast milk that promote the production of new oligodendrocytes from postnatal neural stem cells. In a mouse model of neonatal inflammatory WMI, administration of TT-20 promoted the production of new periventricular oligodendrocytes, improved myelination in the white matter regions most commonly injured in premature babies, and rescued associated motor deficits.


Impact of the Project

Clinical

Dr. Benner and his team are developing an intravenous formulation of a drug to treat WMI in preterm infants, to preclude CP.

Currently, there is no treatment for WMI in pre-term infants, and no treatment or prevention for CP. As of April 2020, pilot data have been collected in rodent models, and early IND-enabling studies are on track with the aim of submitting a pre-IND meeting request to the FDA in Q3 2021.

By Q4 2022, results of a phase 1b clinical trial (n = 30) will be assessed to obtain initial safety data and determine optimal drug dosing for this population. The end result will be the availability of an intravenous formulation for preterm infants that is a first-in-class remyelination treatment able to prevent CP and reduce lifetime costs.

Economic

Shorter term economic benefits include license agreements and patents to protect the intellectual property of the use of TT-20. A startup company, Tellus Therapeutics Inc., was established in October 2018 and is leading the efforts to translate the technology for clinical use in the pediatric population.

Longer-term economic benefits include cost savings and effectiveness, including the potential to avoid the approximately $1.5 million U.S. lifetime costs for caring for one child with CP, decreasing caregiver burden, and improving quality of life of patients.

This technology doesn’t just have the capacity to lower healthcare costs, however: this technology is designed to save lives and improve the quality of life of patients.

Community

One of the benefits of this technology is the potential for preventing CP, which will greatly improve the quality of life for patients and those around them, while significantly reducing lifetime care costs and the associated caregivers’ burden.

Prevention of CP or the reduction of severity will be a lifelong benefit for affected infants and their communities.
