A Phase II Trial of Avelumab or Hydroxychloroquine With or Without Palbociclib to Eliminate Dormant Breast Cancer (PALAVY)
Abramson Cancer Center at Penn Medicine
Summary
This clinical trial will assess the safety and early efficacy of Hydroxychloroquine or Avelumab, with or without Palbociclib, in early-stage ER+ breast cancer patients who are found to harbor disseminated tumor cells (DTCs) in the bone marrow after definitive surgery and standard adjuvant therapy.
Description
The overarching goal of this clinical trial is to reduce the incidence of incurable recurrent metastatic breast cancer by targeting the precursors of these recurrences, bone marrow disseminated tumor cells (DTCs) present after definitive treatment. This trial targets unique mechanisms by which DTCs maintain a dormant phenotype (autophagy) and by which they escape dormancy (upregulation of the cyclin-dependent kinase4/6 (CDK4/6) pathway and microenvironmental factors such as immune evasion). The selection of these agents is based upon strong preclinical data demonstrating the relevance of autop…
