Frequently asked questions about ZIO-101

What is ZIO-101 used for?

ZIO-101 is an investigational small molecule developed for oncology indications, including acute leukemia, multiple myeloma, and solid tumors. It has been studied in Phase 1 clinical trials in patients with hematologic cancers such as acute leukemia, chronic myeloproliferative disease, chronic lymphoproliferative disease, multiple myeloma, lymphoma, and poor-risk myelodysplasia, as well as in solid tumors.

What does ZIO-101 target?

ZIO-101 targets the hedgehog signaling pathway. The hedgehog pathway is involved in cell growth and differentiation, and its dysregulation is implicated in several cancers. By targeting this pathway, ZIO-101 is designed to interfere with signaling that may promote tumor growth.

Who is developing ZIO-101?

ZIO-101 is being developed by Alaunos Therapeutics, Inc., which trades under the ticker symbol TCRT. The company is responsible for the clinical development of the drug.

What phase is ZIO-101 in?

ZIO-101 is in Phase 1 clinical development. It has completed Phase 1 trials and is not approved by the FDA for any indication. The drug remains investigational.

What clinical trials is ZIO-101 in?

ZIO-101 has been evaluated in three completed Phase 1 trials: NCT00592046 in hematologic cancers, NCT00591396 in solid tumors, and NCT00303199 in multiple myeloma. All trials are completed, and no active trials are currently listed.

Is ZIO-101 the same as darinaparsin?

Yes, ZIO-101 is also known as darinaparsin. The two names refer to the same investigational drug.
