AMXI-5001:Dose Escalation Phase I, AMXI-5001:Dose Expansion Phase II

Summary

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.

Detailed Description

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.

Study Plan

AMXI-5001 Treatment

EXPERIMENTAL

Single Arm Study, all participants will receive AMXI-5001.

  • DRUG:

    AMXI-5001:Dose Escalation Phase I

    Description:

    Phase I will enroll up to 70 participants to identify the Recommended Phase II daily dose in the treatment of various cancers and to characterize the safety, pharmacology, and clinical efficacy of AMXI-5001. AMXI-5001 is administered orally twice daily, with food. AMXI-5001 is administered weekly on a continuous 7-day schedule. Each cycle is 28 days.
  • DRUG:

    AMXI-5001:Dose Expansion Phase II

    Description:

    Phase II will enroll up to 52 study participants to further characterize the safety, pharmacology, and clinical efficacy of AMXI-5001. AMXI-5001 is administered orally twice daily, with food. AMXI-5001 is administered weekly on a continuous 7-day schedule. Each cycle is 28 days.
