NCT ID NCT06711523

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 3 trial tests a long-acting injection called PEG-G-CSF to prevent severe neutropenia (dangerously low white blood cell counts) after chemotherapy in 250 women with breast cancer. Participants receive either the test drug or the already-approved Neulasta. The goal is to see if the new injection works as well and is safe, potentially offering another option to reduce infection risk during cancer treatment.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

PEG-G-CSF (a long-acting injection to boost white blood cell counts)

What this could lead to

If successful, this could offer a similar option to Neulasta for preventing dangerous drops in white blood cells after chemotherapy, reducing infection risk.

What could go wrong

This is a late-stage trial, but it only includes breast cancer patients on specific chemo regimens. Results may not apply to all cancers or treatments. Side effects like bone pain or allergic reactions are possible.
