Scientific title

ASPEN-09: A Phase 1b/2, Multicenter, Multi Arm Study of Evorpacept in Combination With Anti-cancer Therapies in Advanced / Metastatic Malignancies

Summary

The purpose of this study is to evaluate evorpacept with anti-cancer therapies in advanced/metastatic malignancies. The study is comprised of the following substudies: * Metastatic HER2+ breast cancer (MBC) - single-arm substudy 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. * Metastatic colorectal cancer (CRC) - dose escalation phase to evaluate evorpacept in combination with other drugs. This substudy is not recruiting. * Recurrent/metastatic head and neck cancer (HNSCC) - dose escalation phase to evaluate evorpacept in combination with other drugs. This substudy is not recruiting.

(all substudies):

* Participants must have at least one measurable lesion as defined by RECIST v1.1.* Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) must be 0 to 1. * Life expectancy of at least 3 months * Participants must have recovered from all AEs due to previous therapies, procedures, and surgeries to baseline severity or ≤Grade 1 per NCI CTCAE v5.0 except for AEs not deemed reversible which do not constitute a safety risk by Investigator judgment

MBC substudy:

* Histologically confirmed invasive HER2 positive breast cancer* Available tumor tissue (FFPE slides or block). A fresh biopsy is preferred but optional. * Received at least one prior line of therapy including T-DXd for locally advanced/metastatic HER2 positive 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. * 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) * LVEF ≥50% * Adequate renal function (estimated creatinine clearance ≥30 mL/min as calculated using the Cockroft-Gault 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).
