Frequently asked questions about Glycerophosphate

What is Glycerophosphate used for?

Glycerophosphate is an organic phosphate small molecule being developed for parenteral nutrition, where it is intended to supply phosphate to patients who cannot take nutrition by mouth. It is also known as Sodium Glycerophosphate Injection. Baxter International Inc. is developing it, and it has been studied in a single completed Phase 1 trial.

Who makes Glycerophosphate?

Glycerophosphate is being developed by Baxter International Inc., which trades on the New York Stock Exchange under the ticker BAX. The company sponsored the Phase 1 bioequivalence study of Sodium Glycerophosphate Injection conducted in the United States.

What phase is Glycerophosphate in?

Glycerophosphate is in Phase 1 development. One Phase 1 trial has been completed, and no active trials are currently listed. The completed study was a randomized, double-blind, controlled bioequivalence trial that enrolled 42 healthy adult volunteers in the United States.

What clinical trials is Glycerophosphate in?

Glycerophosphate has been evaluated in one completed Phase 1 trial, NCT06842121, titled A Bioequivalence Study Comparing Organic Phosphate (Sodium Glycerophosphate Injection) to Inorganic Phosphate (Sodium Phosphates Injection, USP). The trial enrolled 42 healthy volunteers aged 18 years and older in the United States and compared the two phosphate formulations.

Is Glycerophosphate the same as Sodium Glycerophosphate Injection?

Yes. Sodium Glycerophosphate Injection is another name for Glycerophosphate, the organic phosphate small molecule developed by Baxter International Inc. for parenteral nutrition. The Phase 1 bioequivalence trial NCT06842121 used the Sodium Glycerophosphate Injection name in its title.
