PHILADELPHIA (CBS) — Main Line Health is part of a cutting-edge trial to help develop treatments for patients suffering the most from COVID-19.

More than 20 health systems are participating in the I-SPY COVID-19 trial.

Only patients receiving a high volume of oxygen or on a ventilator are eligible.

The trial’s unique setup involves testing four drugs at the same time, in addition to administering existing therapies.
