What This Trial Is Studying

The Substudy Protocol ASPEN-09-03 is a Phase 2, single-arm, multicenter study evaluating the efficacy, safety, and tolerability of evorpacept in combination with trastuzumab and chemotherapy in participants with HER2-positive metastatic breast cancer who have previously received trastuzumab-deruxtecan. This substudy is actively recruiting. ASPEN-09-03 is a substudy under Master Protocol ASPEN-09, and additional substudies are as follows: * Metastatic colorectal cancer (CRC) - dose escalation phase to evaluate evorpacept in combination with other drugs. This substudy is not open. * Recurrent/metastatic head and neck cancer (HNSCC) - dose escalation phase to…

Eligibility Snapshot
  • : * Histologically confirmed invasive HER2+ breast cancer. * Received at least one prior line of therapy including T-DXd (ENHERTU) for locally advanced/metastatic HER2+ breast cancer. Prior neoadjuvant therapy which resulted in relapse within 6 months of completion of T-DXd will be considered a line of treatment for metastatic disease. Participants who discontinue T-DXd due to intolerance are considered eligible. * Progressed on or following the most recent line of therapy. * Eligible to receive one of the following chemotherapy options (capecitabine, eribulin, gemcitabine, paclitaxel or vinorelbine). * Measurable disease as defined by RECIST v1.1. * LVEF ≥50%. * Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) must be 0 to 1. * Life expectancy of at least 3 months. * Adequate renal function (estimated creatinine clearance ≥30 mL/min as calculated using the Cockcroft-Gault equation or Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. * Adequate liver function: * Total bilirubin ≤1.5 x upper limit of normal (ULN) (≤3.0 x ULN if the participant has documented Gilbert syndrome); * Aspartate and alanine transaminase (AST and ALT) ≤3 x ULN (≤5.0 x ULN if liver involved by metastatic disease). * Participants must have recovered from all AEs due to previous therapies,…
