ATLAS-101 is a Phase I/II clinical trial of AMXI-5001 in adult participants with advanced malignancies who have previously failed other therapies. The study has two phases. The purpose of Phase I (Dose Escalation) is to confirm the appropriate treatment dose and Phase II (Dose Expansion) is to characterize the safety and efficacy of AMXI-5001.

Official Title

A Phase I/II, Open Label, Multi-center, Non-randomized Dose Escalation and Dose Expansion Study of AMXI-5001 in Patients With Advanced Malignancies


AMXI-5001 is an orally available dual PARP (poly adenosine diphosphate [ADP] ribose polymerase) and microtubule polymerization inhibitor. ATLAS-101 is a Phase I/II, open label, multi-center, non-randomized Dose Escalation and Dose Expansion study in participants with advanced malignancies. Study enrollment is approximately 122 participants. All participants receive oral AMXI-5001, twice daily, as monotherapy. Following Phase I (Dose Escalation) to identify the Maximum Tolerated Dose and the Recommended Dose for use in Phase II, additional participants will be enrolled into the Dose Expansion Phase to further characterize the safety, pharmacology, and clinical efficacy of AMXI-5001.
