Frequently asked questions about Eribulin

What is Eribulin used for in Metastatic Breast Cancer?

Eribulin is a small molecule oncology drug being studied for use in metastatic breast cancer. It is currently in Phase 2 clinical development as an investigational therapy. Eribulin is administered as an injection and is being evaluated for its effects on patients with this condition.

What does Eribulin target?

Eribulin targets tubulin proteins, including TUBB4B, TUBB1, TUBA3C, TUBA4A, TUBB3, and TUBA1A. It acts as an inhibitor of these molecular targets, which are components of microtubules, structures essential for cell division. By inhibiting these targets, Eribulin may interfere with cancer cell proliferation.

Who makes Eribulin?

Eribulin is being developed by Gilead Sciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol GILD. The company is conducting clinical research on Eribulin for the treatment of metastatic breast cancer.

What phase is Eribulin in?

Eribulin is currently in Phase 2 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 2 trial is actively recruiting participants to evaluate Eribulin in patients with metastatic breast cancer.

What clinical trials is Eribulin in?

Eribulin is being studied in one active Phase 2 clinical trial with the identifier NCT04986579. This trial, titled 'Scalp Cooling in MBC,' is investigating Eribulin in patients with metastatic breast cancer and chemotherapy-induced alopecia. The study is recruiting 120 participants in the United States.

Is Eribulin the same as Eribulin Mesylate Injection?

Yes, Eribulin is also known as Eribulin Mesylate Injection. These names refer to the same drug product. Eribulin Mesylate Injection is the formulation name, while Eribulin is the generic drug name used in clinical and research contexts.
