About this trial

This study will evaluate the safety, tolerability, and preliminary effectiveness of AMXT 1501 and DFMO when combined with standard treatments for advanced solid tumors. The trial includes two groups:

* Cohort 1: Patients with ER+ / HER2- breast cancer receiving fulvestrant and capivasertib * Cohort 2: Patients with unresectable or metastatic cutaneous melanoma receiving pembrolizumab

The Phase 1b portion will find the recommended Phase 2 dose (RP2D). The Phase 2 portion will further evaluate clinical activity at the RP2D using response criteria for solid tumors (RECIST 1.1).

The study will also evaluate pharmacokinetics, pharmacodynamics, disease control, and overall safety.

Eligibility criteria

Qualifiers

Understand and sign the informed consent form (ICF) and be willing to comply with all study procedures before any study specific procedures are conducted.

≥18 years old at the time of signing the informed consent.

Diagnosed with unresectable, locally advanced, or metastatic solid tumors including ER+ HER2- breast cancer (Cohort 1) or melanoma (Cohort 2)

Patients must be willing to undergo a fresh tumor biopsy at Screening and during treatment if safe and clinically feasible. An archival sample is allowed if obtained within 1 year prior to the first dose of study drug. However, lack of tumor biopsy by itself will not preclude patients from enrollment.

Disqualifiers

Intolerant to any component of combination or standard of care therapies.

History or presence of clinically relevant central nervous system (CNS) pathology such as epilepsy, seizure, paresis, aphasia, stroke, severe brain injury, dementia, Parkinson's disease, cerebellar disease, organic brain syndrome, or psychosis. Patient has known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable, i.e., without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study treatment.

Active inflammatory neurological disorders (e.g., Guillain-Barre Syndrome, amyotrophic lateral sclerosis, multiple sclerosis).

Treatment with radiation therapy, surgery, chemotherapy, or immunotherapy within 4 weeks prior to study entry (6 weeks for nitrosoureas or Mitomycin C). No prior use of Adriamycin is allowed. Limited prior palliative radiation may be permissible no less than 2 weeks prior to C1D1 with approval from the Sponsor Medical Monitor or designee.
