Frequently asked questions about Erythromycin

What is Erythromycin used for?

Erythromycin is a small molecule being studied in healthy volunteers. It is being evaluated in a Phase 1 clinical trial to assess its effects on the pharmacokinetics of relugolix, estradiol, and norethindrone in healthy postmenopausal women, and on the pharmacokinetics of relugolix in healthy adult men.

What does Erythromycin target?

Erythromycin is a macrolide antibiotic that targets bacterial protein synthesis. In the context of the Phase 1 trial, it is used as a potential inhibitor of drug-metabolizing enzymes to study its interaction with relugolix, estradiol, and norethindrone.

Who makes Erythromycin?

Erythromycin is being developed by Roivant Sciences Ltd., a biopharmaceutical company traded on the NASDAQ under the ticker ROIV. The company is conducting a Phase 1 clinical trial to evaluate the drug's effects on the pharmacokinetics of other medications in healthy subjects.

What phase is Erythromycin in?

Erythromycin is in Phase 1 clinical development. The Phase 1 trial, NCT04714554, has been completed. The study enrolled 43 participants and was conducted in the United States. Erythromycin is an investigational drug in this context and is not approved for this use.

What clinical trials is Erythromycin in?

Erythromycin is associated with one completed Phase 1 clinical trial, NCT04714554. The trial studied the effects of erythromycin on the pharmacokinetics of relugolix, estradiol, and norethindrone in healthy postmenopausal women, and on relugolix in healthy adult men. It enrolled 43 participants in the United States.

Is Erythromycin the same as other drugs?

Erythromycin is a well-known macrolide antibiotic, but in this clinical trial context, it is being studied as a pharmacokinetic probe. No alternative names for this specific use are provided. The trial focuses on its interaction with relugolix, estradiol, and norethindrone.
