Metformin after bone cancer treatment to prevent relapse

OsteosarcomaEwing Sarcoma

Treatments studied

Part of Cancer clinical trials.

This Phase 2 study tests whether taking metformin after surgery and chemotherapy can reduce the risk of bone cancer coming back in people at high risk of relapse. You may be eligible if you have osteosarcoma or Ewing sarcoma that is not currently spread and you meet specific lab and health criteria.

Who can take part

  • Have osteosarcoma or Ewing sarcoma, and the cancer is not metastatic (not spread to other body parts)
  • Be at least 14 years old
  • Be in a high-risk situation: after initial chemotherapy with low tumor necrosis or after being disease-free following a first relapse (per the study’s timing rules)
  • Have the right timing: able to start screening and begin metformin within about 30–45 days after finishing chemotherapy or local surgery/relapse
  • Be able to swallow pills and not be in another clinical study
  • Have good kidney and liver function on screening labs (and you should not have certain kidney/liver or oxygen-blood-flow problems)

Regorafenib to help prevent cancer return after treatment

This Phase 2 study tests whether regorafenib, given after your main treatments, can help keep high-grade bone sarcoma from coming back or progressing. It checks safety and whether this “maintenance” approach works better than best supportive care alone.

Surufatinib plus chemotherapy before surgery for osteosarcoma

This Phase 2 trial studies whether surufatinib combined with chemotherapy given before surgery can shrink osteosarcoma and improve outcomes. It may help by attacking the tumor from more than one angle before the main treatment step.

Metformin before chemoradiation for esophageal cancer

This trial tests if taking metformin (a diabetes pill) before standard chemoradiation can make esophageal cancer respond better. You take metformin for 2 weeks before starting standard treatment, and doctors will check your tumor with two endoscopies to see how it changes.
