Who makes PEG asparaginase?

PEG asparaginase is developed by Amgen Inc., a biopharmaceutical company traded on NASDAQ under the ticker AMGN.

What phase is PEG asparaginase in?

PEG asparaginase is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. Two Phase 1 trials are listed, one completed and one recruiting.

What clinical trials is PEG asparaginase in?

PEG asparaginase is associated with two clinical trials. NCT02303821, a completed Phase 1 study of carfilzomib with induction chemotherapy in children with relapsed or refractory ALL, enrolled 141 participants. NCT05848687, a recruiting Phase 1 trial for infants with ALL, plans to enroll 90 participants.

Is PEG asparaginase the same as pegaspargase?

PEG asparaginase is a form of asparaginase that is pegylated. It is also known as pegaspargase, a common name for this drug. The trials listed use PEG asparaginase as part of combination regimens.
