Study Overview

A Trial of AMXI-5001 for Treatment in Patients With Advanced Malignancies

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.

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.

Arms and Interventions

Participant Group/ArmIntervention/Treatment
EXPERIMENTAL: AMXI-5001 Treatment

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

DRUG: AMXI-5001:Dose Escalation Phase I

  • 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, w

DRUG: AMXI-5001:Dose Expansion Phase II

  • 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
Primary Outcome MeasuresMeasure DescriptionTime Frame
Determine the Maximum Tolerated Dose (MTD)The highest dose is defined at which no more than 1 of 6 evaluable participants has had a Dose Limiting Toxicity (DLT) according to NCI CTCAE V5.0 criteria and determination by Investigator and Data and Safety Monitoring Committee.Approximately 12 months
Determine the Recommended Phase 2 Dose (RP2D) for AMXI-5001 as monotherapyThe RP2D is based upon the review of all available data including safety, pharmacokinetic, preliminary anti-tumor activity, and MTD.Approximately 12 months
Characterize safety profile of AMXI-5001The safety profile of AMXI-5001 is defined by the incidence of treatment emergent adverse events, laboratory abnormalities, and ECG measurements.Approximately 24 months
Secondary Outcome MeasuresMeasure DescriptionTime Frame
Measure concentration of AMXI-5001 in plasma samplesConcentrations of AMXI-5001 in plasma samples at different time points are measured. Standard pharmacokinetic parameters are calculated.Approximately 24 months
Determine change in anti-tumor activity following administration of AMXI-5001Overall Survival (OS), Objective Response Rate (ORR), Duration of Response (DOR), and Progression-free Survival (PFS) are assessed by RECIST V1.1 criteria.Approximately 24 months
