Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests a combination of two drugs—sacituzumab govitecan (given through a vein) and pemetrexed (given into the spinal fluid)—for people with HER2-negative breast cancer that has spread to the lining of the brain and spinal cord (leptomeningeal metastases). This condition is very serious, with survival typically only 3-6 months. The trial aims to find a safe dose and see if the combo can help control the disease. About 34 adults will take part.
