ATX-101 Trial Summary

This trial is testing a new drug, ATX-101, to see if it's effective in treating two types of cancer, dedifferentiated liposarcoma (LPS) and leiomyosarcoma (LMS). ATX-101 is an IV drug that's thought to work by blocking the interaction of a protein called PCNA with other proteins involved in the stress response. This trial will see if ATX-101 can disrupt these interactions and help treat the cancer.

Eligible Conditions
  • Liposarcoma
  • Leiomyosarcoma

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Has ATX-101 been granted clearance by the Food and Drug Administration?

Answered by AI

What qualifications are necessary to be enrolled in this clinical experiment?

"34 individuals aged 18 to 99, with leiomyosarcoma and an ECOG performance status of ≤2 are eligible for this trial. Additionally, they must have received previous systemic treatment within the last 6 months that aligns with the type of sarcoma (LMS: Anthracycline-based chemotherapy or gemcitabine/docetaxel; LPS: No specification as to prior treatment). As safety data on ATX-101 in minors is unavailable, children cannot participate."
